During the ceremony, Technion President Prof. Uri Sivan said that “leadership and personal accountability are the most effective and important responses to the challenges and difficulties that the events of recent days have repeatedly highlighted.”

On May 24th, the Technion awarded Ph.D. diplomas to 199 graduate students in a festive and moving ceremony at the Kellner Amphitheater. The ceremony was attended by the new graduates, their families, Technion management, Faculty deans, and staff.

Approximately 43% of new Ph.D. graduates are women, a new record, and a significant increase over previous years. Most of the graduates (124) are native Israeli, and the rest are from all over the world, including the U.S., Canada, France, Austria, Ukraine, Uruguay, Italy, Belgium, Brazil, Germany, India, and China. 

The faculties with the highest number of graduates are the Rappaport Faculty of Medicine (27), Civil and Environmental Engineering (19), and Physics (16); 205 supervisors oversaw the doctoral candidates throughout their studies. Overseeing the supervisors is Head of the Faculty and Dean of Biotechnology and Food Engineering, Prof. Marcelle Machluf whose five students were among those receiving a Ph.D. degree during the ceremony.

Technion President Prof. Uri Sivan: “This is a celebration for all of you, who today can add ‘Dr.’ to your name, a celebration for your families who have accompanied you along the way, and a celebration for us, your teachers. We’ve accompanied you on the long road, taught you what we know, and just as importantly, we’ve learned from you. We have no doubt that you have acquired the best professional tools here. If you also know how to deal with the professional dilemmas you come across in social, environmental, and ethical contexts if you are a beacon of tolerance, equality, and empathy, and if you continue to ask questions – then we have done our job.”

Dean of the Graduate School Prof. Dan Givoli: “I have always believed that the two most important factors that impact the Technion’s prosperity are faculty members and doctoral students. You and your supervisors are the research foundations of the Technion.” 

In addition, Prof. Givoli presented some data related to the current cohort: “One-third of the graduates took the direct Ph.D. track; three of the graduates are new immigrants, who immediately began their Ph.D. research at the Technion, in 2016; two graduates are a married couple – Dr. Ekhlas Homede Abo Jabal and Dr. Mohammad Abo Jabal, who completed their studies at the Technion and now teach at the Guangdong Technion-Israel Institute of Technology (GTIIT) in China. The ratio of supervisors to students was very high because many of them had more than one supervisor – a result of blurring boundaries between the disciplines and strengthening the interdisciplinary nature of scientific research.”

This trend is reflected in the research of Dr. Gil Wang of the Faculty of Civil and Environmental Engineering, who gave the valedictory speech on behalf of the new graduates. Dr. Wang completed his Ph.D. under the supervision of three Technion faculty members: Prof. Yiska Goldfeld, Prof. Nitai Drimer, and Prof. Yehiel Rosenfeld. “At the Technion, I was exposed to the heterogeneous, diverse, Israeli society, rich in colors and beliefs,” he said at the ceremony. “I look at the Technion – at us – and it gives me hope and fills me with optimism. The Technion model, which emphasizes perseverance, hard work, and the constant pursuit of excellence, makes any polarization in Israeli society irrelevant.”

Dr. Wang added that some of his peers “will continue their research here and overseas, some will go into the industry, others will go into teaching, and others to consulting, management and startups; but all fellow graduates will continue to lead and excel because this is their way, this is the Technion way.”

“Leadership and personal accountability are the most effective response”

Technion President Prof. Uri Sivan said: “In recent weeks, we’ve learned that the Technion plays a major role in dealing with both external and internal threats. The external crisis highlighted the extensive technological role Technion graduates played, and still play. But I want to focus on the other role of the Technion, as a factor in the healing of society’s divisions. Since its inception, the Technion has championed equality and tolerance. For 100 years, it has maintained an apolitical identity and has given male and female students the opportunity to live and learn in an atmosphere of tolerance, equality, and mutual respect, as part of our social commitment. We expect you to continue in this way. Leadership and personal accountability are the most effective and important response to the challenges and difficulties that the events of recent days have repeatedly highlighted.”

Technion’s youngest new Doctor is Arik Girsault, who completed his Ph.D. at the Faculty of Biomedical Engineering under the supervision of Prof. Amit Meller. Arik, 28, holds dual French and Swiss citizenship and is likely to soon be granted Israeli citizenship as well. 

He was born in Paris, the son of a Swiss businessman and a French lawyer, and spent a large part of his childhood and youth moving from city to city due to his parents’ work. He studied at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, from which he received his BSc and MSc in Life Sciences and Bioengineering. As he neared the end of his MSc program, “some of my professors recommended that I continue studying toward a Ph.D. at the Technion, which fitted in perfectly with my Zionist sentiments,” he says. “I wanted to spend time in Israel.”

Arik arrived at the Technion and met with some of the staff members at the Faculty of Biomedical Engineering. He based his decision on his impression of the supervisor and the students in the lab. For four and a half years, he worked on his major project, under Prof. Amit Meller’s supervision: the development of an advanced microscope for monitoring intracellular biomolecular processes at high temporal resolution. According to Prof. Meller, “Arik was an outstanding multidisciplinary student. He developed high skills in building a STED (Stimulated Emission Depletion) optical microscope, in preparing complex biological samples, and in computerized information processing using software that he himself developed.”

Arik devoted the little free time he had during his research to playing on the Technion tennis team and to reading books on Jewish thought. After completing his degree, he returned to visit his parents in Switzerland, but this is by no means his final destination. Arik decided to make Aliya and has already completed most of the formal arrangements. And what will he be doing here? “For the time being, all options are open – academia, industry, everything – but I have a feeling that I will be deciding in favor of the startup world, which seems challenging and interesting, and there is nowhere better than Israel to do this.”

The oldest new Doctor is Dr. Tirza Lauterman, 58, who completed her thesis under the supervision of Prof. Rakefet Ackerman of the Davidson Faculty of Industrial Engineering and Management. Dr. Lauterman first came to the Technion as a soldier-student in 1981, and after completing a BSc in Information Systems Engineering at the Faculty of Industrial Engineering and Management, she enlisted in the Navy, where she served for many years. Over the years, she advanced through the ranks, and her last position was Head of the Information Systems Branch of the Navy. In 2007, she retired with the rank of Lieutenant Colonel. 

In 2010, nearly 30 years after she began her undergraduate studies, she began studying toward her master’s degree that continued into a Ph.D. Her research was in the field of problem-solving, and specifically the first impressions of people on encountering a problem and the consequences of this impression on coping with the problem. “After much research, we have come to the conclusion that first impressions determine a lot, just as they do with meeting people, and it significantly affects the time and effort that they will invest in solving the problem, as well as the final answer that comes after deep thought,” she says. “Acknowledging the existence of primary judgment is important for understanding engineering problems, and it also affects how tests and challenges are designed. If we design them in a way that will create confidence in the person’s ability to solve the problem, we will improve the person’s chances of solving it, and on the other hand, if we transmit an exaggerated impression of ease, the person might waste time trying in vain.”

Dr. Lauterman currently teaches at the Technion and at the Open University, and in the coming academic year, she will also begin teaching at Bar Ilan University. She is married, a mother of three, and a grandmother.

 

In a recent breakthrough, scientists from the Technion Faculty of Biomedical Engineering were able to achieve recognition of specific geometric patterns – for example, letters – by engineered microbe colonies imitating an artificial neural network. The scientists’ method relies on a modification of the way communication occurs within microbe colonies in nature. The study, led by Dr. Ximing Li and Assistant Professor Ramez Daniel, was published in Nature Communications.

The interest of Prof. Daniel’s lab lies in synthetic biology, specifically in generating biological circuits, in essence combining the principles of biology and electronics. Like electronic switches that can be turned on and off, cells are engineered to “turn on” and perform a function, for example, fluorescence, in response to a particular stimulus. Using this technique, the group has already engineered biological sensors that recognize the presence of arsenic and other poisons in water or the presence of blood in urine.

But cells are capable of more complex functions than a simple yes/no switch. Microbial colonies in nature are capable of communication within the colony. For example, they may respond differently when they are alone and when there are many of them together. This phenomenon, called “quorum sensing,” is also at play for example when our immune system mobilizes against an infection – information is passed regarding what the pathogen is, how much of a response is required, and more. One cell alone might be “dumb,” but the colony is “smart.” It is this phenomenon that Prof. Daniel’s group utilized in order to increase the algorithmic complexity of the task by a factor, and, for the first time, generate a biological circuit acting as an artificial neural network, capable of performing the relatively complex task of pattern recognition. Its building blocks: engineered E. coli bacteria.

Geometric patterns are a proof of concept of what biological circuits acting as an artificial neural network can do. In the future, we might see bioengineered systems monitoring toxins, diagnosing cancer, and being used in tissue regeneration. We might even have biological computers. It is interesting to observe how synthetic biology, seeking to imitate electronics in biological systems, has come a full circle, creating a likeness of an artificial neural network, which is of course inspired by the human brain – itself a biological system.

Prof. Daniel started working on biological computing during his postdoctoral fellowship at the Massachusetts Institute of Technology (MIT), initially on analog computation. Biological circuits acting as an artificial neural network are a novel development and a conceptual advancement in the same field. It was made possible with the assistance of Associate Professor Netanel Korin, also from the Technion Faculty of Biomedical Engineering. Dr. Li is a postdoctoral fellow in Prof. Daniel’s laboratory. She completed her Ph.D. in computational neuroscience at the University of Ohio.

Technion and Hospital Israelita Albert Einstein, one of Latin America’s largest hospitals, sign MOU to support student exchange, collaborative research, and clinical trials

The Technion – Israel Institute of Technology has signed a Memorandum of Understanding (MOU) with Hospital Israelita Albert Einstein in Sao Paulo, Brazil, establishing a three-year collaboration between the Technion’s Rappaport Faculty of Medicine and the Brazilian hospital, one of Latin America’s largest. The MOU will support student exchange, clinical trials, and collaborative research projects between the two institutions. 

The ceremony took place via video conferencing on May 6, and the MOU was signed by Technion President Prof. Uri Sivan and President of the Albert Einstein Hospital, Dr. Sidney Klajner. 

Hospital Israelita Albert Einstein specializes in cardiology, oncology, orthopedics, surgery, and neurology. The hospital, which was founded by the Jewish community of Brazil 66 years ago, was named as the best hospital in Brazil in 2020 by Newsweek. As part of the collaboration, students studying at the Technion’s Rappaport Faculty of Medicine will go to the hospital each year for clinical rounds – which most students typically do in hospitals in Israel; similarly, students studying at the hospital in Brazil will be able to do the clinical rotation in the affiliated hospitals of the Technion Faculty of Medicine. In some cases, graduate students studying at the Albert Einstein Hospital will be allowed to spend an extended period at the Technion Faculty of Medicine and its affiliated hospitals.

The connection between the Technion and the hospital was made through Shaul Shashoua, a member of the Friends of the Technion in Brazil. The ceremony was also attended by Technion Vice President for External Relations and Resource Development Prof. Alon Wolf; President of the Friends of the Technion Society in Brazil Salomao Ioschpe; Prof. Dr. Luiz Vicente Rizzo, VP of R&D at the Albert Einstein Hospital; and Prof. Alexandre Holthausen Campos. From the Rappaport Faculty of Medicine at the Technion attended: The Dean, Prof. Elon Eisenberg; Prof. Yaron Har-Shai, Vice Dean for Strategic Development; Prof. Simone Engelender, senior researcher; and others. 

“The Technion and Albert Einstein are two institutions focused on the betterment of people’s lives, no matter where they live, no matter which language they speak, and no matter what their beliefs are,” Technion President Prof. Uri Sivan said at the signing ceremony. “The essence of our collaboration agreement is bettering the lives of people by promoting and disseminating knowledge.” 

President of the Albert Einstein Hospital, Dr. Sidney Klajner: “Our hospital symbolizes the value of saving lives, which is so important in Jewish tradition. Albert Einstein was founded on four Jewish precepts: mitzvah, refuah, chinuch, and tzedakah (good deeds, healing, education, charity). It is very exciting to be here at this moment of signing an agreement between two institutions that share a common aspiration to improve human life in Brazil and Israel.” 

Dean of the Rappaport Faculty of Medicine, Prof. Elon Eisenberg: “The hospital fully understands the importance of inter-institutional cooperation in promoting science and education in medicine. I look to the future with hope and am confident that this is the beginning of an important scientific and educational relationship.”

Prof. Yaron Har-Shai, Deputy Dean of Strategic Development at the Rappaport Faculty of Medicine: “In science, it is impossible to move forward without cooperation, including international cooperation. Therefore, we established an international center in the faculty a few years ago that deals with the faculty’s global relations. Over time, thanks to the support of the deans and the hard work of Matan Raz and Stephanie Schneor, we have partnered with more than 10 leading university hospitals in the U.S., Germany and Australia, mainly for student exchange.  I have no doubt that the exposure of our students to hospitals abroad gives them not only a great deal of knowledge but also a richer view of health systems overseas and makes them better doctors. In addition, the professional relationships that are forged with the medical staff abroad will accompany them during their medical careers.”

Prof. Simone Englander, a faculty member originally from Brazil, played an important role in creating the collaboration with the hospital. “Shortly before the outbreak of coronavirus, a large team of doctors from the hospital in Brazil came here and introduced us to each other… paving the way for future scientific research and collaboration,” she said. 

“There is nothing more satisfying in a president’s post than unleashing the creativity of young people. I look forward to seeing the fruits of your innovation and free spirit,” said Prof. Uri Sivan, President of the Technion, at the opening of the EuroTech Innovation day, hosted by the Technion on April 28, 2021. 

Indeed, Innovation Day was all about creativity and entrepreneurship. Students from the six universities that constitute the EuroTech Alliance enjoyed a rich program jampacked with informative talks, a biomedical engineering hackathon, and a startup competition. Some 850 students from all six participating universities joined the lectures online; 3,000 people were present to vote on the winners of the startup competition; and 49 students were selected out of numerous applicants to participate in the BioMed hackathon.

The full-day online event program was clustered into 30 short lectures, spanning five different themes: Boosting Entrepreneurship, Students on the Forefront of Academia Innovation, From Product to Market, On the Critical Role of Supporting Environments, and Startups & Ventures – with representatives of all universities speaking on each subject. Keynote Speaker Gilad Japhet, Founder & CEO of MyHeritage, shared practical tips for beginning entrepreneurs from his own experience in establishing and expanding Genetic Ancestry Research company MyHeritage.

Startup competition features wearable device, robotic catheter

The day culminated with a startup competition, presenting budding startups (founded in 2020) born in each of the six institutions. The audience could cast a vote to pick their favorite project. The winner of this popular vote was Technion startup Harmony, a FemTech initiative developing a wearable, continuous, and non-invasive tracker to monitor women’s hormonal levels, aiming to ease the process of IVF, but also relevant for avoiding pregnancy, or alternatively for increasing the chances of getting pregnant. Second place was taken by another Technion startup – Robotip Medical, developing a flexible steerable robotic catheter for vascular catherization. Third place went to the Technical University of Denmark startup USOR Design, which is developing a harvest fire prevention system. 

Parallel to the Innovation Day, Technion’s Faculty of Biomedical Engineering hosted the “BME-HACK,” an online hackathon. Approximately 50 students from participating universities and from different scientific fields got a taste of establishing a biomedical startup: they chose medical challenges to focus on, examined what already exists to tackle those challenges, consulted physicians, proposed novel solutions, and worked with mentors from the scientific and the commercial fields to design a product and plan a business model. 

In the end of a long day of ideation and development, after each team presented its solution in a Facebook Live event, four winning teams were chosen to receive a total prize of 2,800 Euros, sponsored by NGT3-VC, Philips and Biosense Webster (J&J). The winning team proposed a solution for the topic of at-home dental caries detection, two teams shared the second place, proposing solutions for the prevention of pressure ulcers and for drug repurposing, and the audience favorite was a proposed treatment for Multiple Sclerosis. The hackathon was organized and supervised by Dr. Yael Rozen, applied research consultant, and Lilach Lorber, Director of External Affairs at the Faculty of Biomedical Engineering.

Celebrating the alliance’s 10th anniversary 

The EuroTech Innovation Day hosted by the Technion marks an important part of EuroTech’s 10th anniversary events. The EuroTech Universities Alliance is a partnership of leading European universities of science and technology, which includes the Technical University of Denmark, the École Polytechnique Fédérale de Lausanne, the École Polytechnique, the Eindhoven University of Technology, the Technical University of Munich, and the Technion – Israel Institute of Technology. It aims to foster both research and entrepreneurship, combining the complementary strengths of its partner universities to jointly achieve multilayered, large-scale initiatives, as well as raising awareness of the opportunities offered by science and technology.

The Innovation Day was organized and managed on behalf of the Technion by Gady Paran, Director of Marketing at t-hub, the Technion’s Entrepreneurship and Innovation Center, and produced by Meital Gotfrid, Head of the Conferences Department at the Technion’s Unit for Continuing Studies.

The Faculty of Electrical Engineering at the Technion will henceforth be known as the Andrew and Erna Viterbi Faculty of Electrical and Computer Engineering – in light of evolving world trends and recent developments in the field 

The Technion Faculty of Electrical Engineering will change its name to The Andrew and Erna Viterbi Faculty of Electrical and Computer Engineering. The addition of the term “Computer” to the title reflects a long process of expansion of the traditional electrical engineering discipline into numerous, diverse spheres related to computer engineering. The Technion Senate recently approved the change of name of the long-standing faculty, which is the largest in the Technion alongside the Henry and Marilyn Taub Faculty of Computer Science.

The Faculty of Electrical Engineering at the Technion was established 86 years ago, in 1935. In 1949, when the State of Israel celebrated its first birthday, the Electrotechnical Department was established under the leadership of Professor Franz Ollendorff, a world-renowned scientist and later recipient of the Israel Prize. In 1956, the faculty was relocated from the historical Technion building in the Hadar neighborhood to today’s campus, and in 1965 it was renamed the Faculty of Electrical Engineering.

Since the faculty’s inception, its alumni have been driving the development of Israeli high-tech. In the words of its Dean Professor Nahum Shimkin, “The title ‘electrical engineering’ has accompanied us for more than five decades. We look back on our past achievements with pride and look ahead to the future and the technological advances yet to come. The present change is designed to reflect the broad fields of research and teaching at the faculty. As a modern, leading academic electrical and computer engineering department, our areas of specialization and research encompass most high-tech related disciplines, including microelectronics and nanoelectronics, electromagnetics and photonics, quantum technology, energy and power systems, electronic circuits and computer chip design, signal and image processing, machine learning and intelligent systems, robotics and control, communication engineering and information theory, computer communication networks, computer systems engineering, and more. Renaming the faculty and expanding its areas of activity are in line with the global trend, and particularly with the U.S., where most of the leading electrical engineering departments have already changed their names similarly.”

Technion President Professor Uri Sivan praised the decision and said, “This is a day of celebration. The change of name reflects the faculty’s most important feature – the ability to innovate and keep abreast of the latest trends and developments. By recruiting outstanding staff members, the faculty has succeeded in continuously broadening its fields of research and teaching, in maintaining its leading position in research in the global arena, and in making a great contribution to the Israeli economy. I know the faculty will not rest on its laurels but will continue to expand its areas of research and teaching into new and future worlds of technology.”

In a video greeting broadcast at the ceremony, Dr. Andrew Viterbi, after whom the faculty is named, said, “I am always happy to congratulate the Technion community – students, professors, and staff, and especially those in the faculty whose name is changing today.” Dr. Viterbi, one of the founders of Qualcomm, inventor of the Viterbi algorithm and past recipient of the IEEE Medal of Honor, made many major contributions to the faculty, the largest of which was $50 million in 2015.

“Electrical engineering and computer science could not exist without each other,” he said. “It’s clear that without the breakthroughs of the electronic engineers and physicists of the 1940s and 50s, there would be no computers in the 19th century, and on the other hand, Professor Charles Begge of Cambridge tried – and failed – to build a computer without electricity, so, today let us rejoice with a Shehecheyanu [prayer] at the recognition of the union between Electrical and Computer Engineering.”

Distinguished Professor Emeritus Jacob Ziv, recipient of the Israel Prize and the EMET Prize for Art, Science and Culture, who recently won the IEEE Medal of Honor – the highest recognition of the International Institute of Electrical and Electronics Engineers – said, “The faculty’s quality is grounded in three foundational pillars that provide reciprocal feedback: a rich study and research program that not only helps graduates to find jobs in industry, but also cultivates their ability to survive in a world of technological innovation; recruitment of the finest students, some of whom will want to progress to graduate studies and pursue research; and recruitment of excellent staff who will conduct future innovative, cutting-edge technology research.”

Faculty Dean Prof. Shimkin added, “This faculty, under its former name, which is proudly borne by more than fifteen thousand alumni, has a privileged standing in the development of the Israeli high-tech industry, and is world-renowned as a center of excellence in research and teaching. Under our new name, we will continue to aspire to carry out world-class cutting-edge research, providing our graduates with the finest engineering education available in all spheres of electrical engineering, electronics and computer engineering.”

Chairman of the Faculty Students Committee Elad Paritzki said, “We students at the faculty love the change of name because it represents the expansion of the faculty’s activities. This is a faculty that is characterized by a young, entrepreneurial spirit and a broad range of disciplines, and when I look back, I know that I made the right choice. On behalf of the students and alumni, I thank the faculty, which is a second home to us all.” 

Associate Professor Omri Barak of the Technion has won a prestigious grant for an international research project on memory in biology, computing, and materials

Associate Professor Omri Barak, a member of the Rappaport Faculty of Medicine and a partner in the Network Biology Research Laboratories at the Lorry I. Lokey Interdisciplinary Center for Life Sciences & Engineering at Technion, has won an HSFP research grant. The grant will support a collaborative research project between Prof. Barak, who will be responsible for the theoretical aspect, and two experimenters: Prof. Nathan Keim of the Department of Physics at the University of Pennsylvania and Prof. Mathew Diamond of the International School for Advanced Studies (SISSA) in Trieste, Italy.

The goal of the project, which is entitled “Memory – from Material to Mind”, is to find common and connecting properties between different memory systems: biological memory, computational memory, and physical memory (shape-memory materials). According to Prof. Barak, “In our joint research, we will be looking for principles that repeat themselves in these different disciplines, and will examine whether insights from one discipline, physical memory, for example, can be applied to another discipline, such as computational memory.”

The three-way collaboration will be based on the input in physics (materials with memory) provided by the American partner, Prof. Keim, and in biology (memory experiments with rats), provided by the Italian partner, Prof. Diamond, with Prof. Barak’s expertise in neural networks serving as a bridge between the two. “In a certain sense,” he explains, “I will be trying to create a common language between the disciplines. The prevalent approach to theoretical research into neural networks is based on complex connections between simple parts. On the other hand, it’s a known fact that neurons themselves are far from simple. Translating the properties of materials with memory into this network language will provide an understanding of the effect of building blocks of greater complexity on the memory capabilities of neural networks. By carefully examining what is common to the different kinds of memory and how they are different, we will attempt to further our knowledge of all three.”

HFSP – The Human Frontier Science Program – funds international frontier research in the life sciences under the umbrella theme “Complex mechanisms of living organisms”. The program mainly funds risky projects of the kind that are unlikely to be supported by the industry, which are executed by researchers who have not collaborated previously.

This year, grants totaling 33 million dollars were approved to support a small minority (4%) of the 709 groups that applied for a research grant. Each of the recipients will receive around 120,000 dollars per year over the three coming years. According to the announcement by the International Human Frontier Science Program Organization, “The 2021 HFSP investigators display remarkable depth in approach and innovative thinking.”

There is much talk about green energy throughout the world. The Paris Agreement incentivizes switching to renewable energy sources, and indeed, green energy appears very attractive, with its promises of no pollution and no need to extract fossil fuels. The sun and the wind are there, and all we need to do is harness them to produce electricity. On the face of it, those same factors should also make green energy cheaper to produce.

What then stands in the way of shifting our energy production to these sustainable sources? And why hasn’t the world already shifted to renewable energy?

One of the challenges of switching energy production to sun and wind is their irregularity: wind rises or dies down. The sun rises and sets, or it is obscured by clouds. At times, energy production using these sources is effective, but at other times, production falls while consumption does not. A power plant that only provides electricity during the daylight hours, for example, cannot answer a population’s needs. It follows that energy must be produced when it can be, and stored, to be released when it is needed. In essence, a solar power plant would need to charge big batteries during the day, to be used during the night. Batteries of such scale, however, are very expensive, both in initial costs and in maintenance.

Understanding why batteries are so expensive requires a closer look at how they function. For commercial use, flow batteries are used. They differ from dry batteries (commonly used in home devices) and lemon batteries (familiar from school experiments) in that the two electrolytes (liquids with dissolved positively and negatively charged particles) are not static, but pumped through the system. A selective membrane separating the two liquids prevents self-discharging. The interacting chemicals on two counter electrodes produce the electric current. 

The membrane, unfortunately, is the most expensive element of the battery stack. Its price accounts for up to 40% of the initial costs of the battery stack. Furthermore, the membrane requires maintenance and must be replaced continually due to wear. The electrolytes, in contrast, can last 20 years or more. Reducing the price of the membrane, or else finding a way to eliminate it, would provide a significant boost to the cost-effectivity of sustainable energy.

This is exactly what Technion M.Sc. student Lihi Amit set out to achieve, under the supervision of Technion Faculty of Mechanical Engineering Professor Matthew Suss from The Nancy and Stephen Grand Technion Energy Program, and working together with Danny Naar, Dr. Robert Gloukhovski, in collaboration with Dr. Gerardo Jose la O’ from Primus Power Inc. Their recent article in ChemSusChem was featured on the journal’s cover.

The researchers’ approach was to entirely eliminate the membrane. If the two electrolytes could flow together without intermixing, in a similar way to how oil and water can share a container without mixing, and only interact with each other in a controlled manner to produce an electric current, the need for the membrane would be eliminated. The team constructed a flow battery using bromine and zinc – cheap and readily available materials — and used a non-propriety complexing agent. The complexing agent trapped the bromine in bubble-like droplets, producing an oil-and-water effect, and releasing only as much bromine as was necessary at any given moment for maintaining the electric current. In effect, the expensive membrane of the battery was replaced with the cheap and fluid membrane of each individual droplet.

The study proved the feasibility of this novel approach to flow batteries and characterized its performance – a necessary step on the way to commercial use. One can hope that in the future cheap membrane-less flow batteries will permit the widespread use of sustainable but inconstant energy sources.

Orr Zohar, who is currently completing his master’s degree in the Viterbi Faculty of Electrical and Computer Engineering at the Technion, has been selected to continue his studies at Stanford University after being accepted to the prestigious Knight-Hennessy Scholars program. Zohar, 26, is the first Technion student to win the scholarship and is the first Israeli to be accepted to the program in the engineering discipline. He will use the scholarship to fund his Ph.D. in Electrical Engineering at Stanford University, where he hopes to develop biomedical imaging tools for neuroscience/neurosurgical navigation.

“My interest in neurosurgical navigation is not coincidental”, he says. “Throughout my childhood, my father has undergone several successful neurosurgical procedures. Unfortunately, about two years ago, our luck ran out and he suffered significant motor-speech impairments. The contrast between the outcomes of his past surgeries and this one highlighted for me the importance of building better tools for surgical navigation.” At the end of this summer, Zohar will be leaving to begin his doctorate at Stanford, where he will focus on the connection between computational photography – a technique that enhances or extends digital photography capabilities through the use of digital computation – and biomedical imaging. 

Zohar began his studies at the Technion’s Wolfson Faculty of Chemical Engineering, where, already in the first semester, he became actively involved in research in the university’s laboratories and was thus exposed to a wide variety of research fields. Moreover, he authored and published scientific articles while still studying for his bachelor’s degree – quite a rare achievement – and continued to do so during his graduate studies.

As an undergraduate, Zohar spent a summer at Stanford, working in the laboratory of Technion alumnus Professor Adam de la Zerda, where, for the first time, he was exposed to the connection between image processing, optics, and medical research. “The time I spent at Stanford,” he says, “profoundly impacted my interests – for the first time, I was exposed to research in the fields of biomedical imaging and image processing, which greatly influenced my academic direction.” Thus, while still completing his bachelor’s degree, Zohar began studying towards his master’s, majoring in signal processing, image processing, and machine learning. In parallel, he worked as a researcher in the Laboratory of Nanomaterial-based Devices, led by Professor Hossam Haick of the Wolfson Faculty of Chemical Engineering, where he developed flexible electronics and nanomaterial-based sensors for medical applications. 

The Knight-Hennessy Scholars program aims to develop a community of emerging leaders capable of working across disciplines and cultures while preparing them to address the world’s challenges through innovation and collaboration. The scholarship is considered one of the world’s most prestigious graduate-level scholarships, where outstanding students and promising leaders can pursue the graduate degree of their choice at Stanford. Funding includes tuition and associated fees, a living stipend, and is awarded to up to one hundred candidates from all over the world every year.

 

Three Technion projects will be tested onboard the International Space Station, as part of the Ramon Foundation and the Israeli Ministry of Science and Technology’s “Rakia Mission.” The projects selected for the mission were announced today at the Peres Center for Peace and Innovation. 

Speaking in the name of all winning projects, Prof. Moran Bercovici of the Technion’s Faculty of Mechanical Engineering said this is “an adrenaline shot – there are no other words to describe what this mission does to the Israeli space community. This is an extraordinary opportunity on every scale. The schedule is crazy, the challenges are immense, but we will make it; this is in our Israeli DNA, this is what we’re good at. I want to thank all partners: the Ramon Foundation, the Ministry of Science and Technology’s Israeli Space Agency and Rakia Mission’s scientific-technological committee. And a special thank you to Eytan Stibbe for his choice not to content himself with a personal experience, but to devote to science this amazing journey, on which he is taking us all.”

Eytan Stibbe, one of the founders of the Ramon Foundation, is scheduled to fly to the International Space Station (ISS) in early 2022, as part of the Axiom Space Ax-1 Mission, pending NASA and Axiom approvals – the first private astronaut mission to the space station. This will make him the second Israeli in space, after Ilan Ramon, who perished in the Columbia Space Shuttle accident.

During his time at the International Space Station, Stibbe is expected to carry out several experiments, offering an opportunity for Israeli researchers and entrepreneurs to examine the feasibility and viability of initiatives, and to advance space research and products. The experiments were recently selected by a science and technology committee appointed by the Ramon Foundation. This space mission assists in overcoming one of the main barriers to entering the aerospace industry – the high cost of astronaut hours for carrying out the research. 

Three revolutionary Technion projects were selected to be tested by Stibbe onboard the International Space Station:

The laboratory of Prof. Moran Bercovici at the Faculty of Mechanical Engineering plans to demonstrate the first-ever fabrication of optical components in space. The Fluidic Telescope Experiment (FLUTE) was designed and built by Dr. Valeri Frumkin, Mor Elgarisi, and Omer Luria, under the guidance of Prof. Bercovici, in collaboration with a team of researchers at NASA, led by Dr. Edward Balaban. The experiment onboard ISS will investigate the ability to leverage the microgravity environment to produce high-quality lenses by shaping liquids into a desired form, followed by their solidification. A successful demonstration onboard the ISS will pave the way for fabrication of advanced optical components in space, including the creation of extremely large space telescopes, overcoming today’s launch constraints. 

The teams of Prof. Ehud Behar and Prof. Shlomit Tarem from the Physics Department, spearheaded by Ph.D. student Roi Rahin, are developing a gamma-ray burst localizing instrument – a device they named GALI. Gamma ray bursts are produced by exploding stars going to supernova, as well as by the collision of neutron stars. The same events also produce gravitational waves, bringing the study of the two phenomena into close association. The main challenge facing scientists is being able to localize in the sky where the gamma ray burst is coming from, which would then allow astronomers around the world to point their telescopes towards the event. GALI improves on earlier detectors by utilizing sensors significantly smaller than were previously used, arranged in an innovative 3D array. It is thanks to this unique arrangement that, while being much smaller than previous gamma-ray burst detectors, GALI promises to be more precise in its directionality capabilities.

The third project is a tiny engine for CubeSats – miniature satellites made of cubic modules 10 cm × 10 cm × 10 cm in size – which started its development in the Aerospace Plasma Lab at the Asher Space Research Institute. Headed by Dr. Igal Kronhaus of the Faculty of Aerospace Engineering, the engine is now being commercialized by Space Plasmatics. The lab’s engine, called “Inline-Screw-Feeding Vacuum-Arc-Thruster,” and its fuel supply together, are no bigger than a human finger, but can provide enough impulse to maintain a flight of satellites in a formation for months or more. The fuel, a small titanium wire, is safe to hold in one’s hand. The engine will be placed on the exterior of the International Space Station and be operated under conditions of hard vacuum and extreme temperatures.

Two more of the selected projects have their roots in the Technion: one is by Aleph Farms – a cultured meat startup. Aleph Farms’ technology was developed based on the research of Prof. Shulamit Levenberg of the Technion’s Faculty of Biomedical Engineering. The other is by OncoHost – a personalized cancer treatment startup, based on research conducted by Prof. Yuval Shaked of the Rappaport Faculty of Medicine at the Technion.

All projects must now undergo a rigorous design review process in order to be ready to launch.

Nir Cohen of Moshav Neta’im, an 11th-grade student at the Gymnasia HaRealit High School in Rishon LeZion, won a silver medal at the 55th Mendeleev Chemistry Olympiad, which took place online this year with the participation of 25 countries. The Mendeleev Olympiad has been held for 55 years, and Israel has participated in the event since 2016. The team was trained at the Schulich Faculty of Chemistry at the Technion, under the guidance of Professor Zeev Gross and the team’s head coach, Dr. Izana Nigel-Etinger.

At the end of the process, which included three selection phases and intensive practice sessions, eight students had the privilege of being chosen to participate in the Olympiad: Nir Cohen, an 11th-grade student at the Gymnasia HaRealit High School in Rishon LeZion; Noya Dishon, an 11th-grade student at the Ort Psagot High School in Karmiel; Itamar Steinitz, a 12th-grade student at the Kfar Hayarok School in Ramat Hasharon; Salakh Bshara, a 12th-grade student at the Ibrahim Kassam Amal Multidisciplinary School in Tira; Sean Cherneyev, a 12th-grade student at the Darca Danciger School in Kiryat Shmona; Neta Eiger, a 10th-grade student at the Shaked Darca Secondary School in Sde Eliyahu; Simion Kotliar, a 10th-grade student at the Third Comprehensive School in Ashdod; and Sheli Skop, a 12th-grade student at the Kfar Hayarok School in Ramat Hasharon.

Prof. Gross, who is head of Youth Programs at the Faculty of Chemistry, said, “The importance of participating in the Mendeleev Olympiad goes above and beyond the experience and the privilege because it prepares and seasons the students for the IChO, the International Chemistry Olympiad, in which 84 countries take part.”

This year, the IChO will be held online from July 25 to August 2.

The four International Olympiads in Sciences for Youth are the product of a joint venture between the Future Scientists Center, established by the Maimonides Fund, and the Israeli Ministry of Education, which are also deeply involved in processes of examination, lessons learned, and policy crafting.

PTC has entered into a long-term strategic collaboration agreement with the Technion – Israel Institute of Technology, under which PTC will establish a research and development center and invest NIS 15 million ($5 million USD) into the Technion’s main campus in Haifa. Under the terms of the agreement, PTC and the Technion will jointly research and upgrade learning processes relating to advanced manufacturing technology. PTC’s Haifa development center will relocate to the Technion under the leadership of Dr. Michael Reitman. 

PTC has also allocated an annual budget for joint research in industrial IoT, augmented reality, simulation, and generative design. The allocation supports Technion faculty by providing software products; awarding scholarships and incentives to students and researchers; initiating hackathons and contests, and sponsoring educational programs.

“Today, scientific and technological breakthroughs need both multidisciplinary research and close collaboration between academia and industry. Industry is at the forefront of active implementation and is well acquainted with market needs, whereas academia brings basic scientific knowledge and research depth,” said Prof. Uri Sivan, President, Technion – Israel Institute of Technology. “This is why, in the past few years, Technion has placed greater emphasis on working to tighten its connections with the industry, and the present agreement is the culmination of a long-standing relationship between Technion and PTC. We believe the agreement enables both parties to gain ground, grow, and reap the benefits of each other’s strengths.”

Announced in 2014, the initial agreement between PTC and Technion jumpstarted a robotics and digital content program for the Science and Technology department, including a teaching laboratory for industrial IoT, computer-aided design, manufacturing, and augmented reality, among other STEM topics. As a result of the long-standing collaboration, Technion alumni have joined PTC to lead the company’s Haifa development center, PTC’s second-largest center outside the U.S.

“The importance of collaboration between academia and industry is recognized worldwide,” said Ziv Belfer, Divisional Vice President of Global Research and Development and General Manager, PTC. “PTC has enjoyed 15 years of successful collaboration with Aachen University in Germany, including the construction of a separate campus that also houses R&D laboratories for companies that collaborate with academic staff. Several projects subsequently became success markers for commercial companies, and we look forward to replicating these efforts with the Technion in Israel.”

PTC (NASDAQ: PTC) enables global manufacturers to realize double-digit impact with software solutions that enable them to accelerate product and service innovation, improve operational efficiency, and increase workforce productivity. In combination with an extensive partner network, PTC provides customers flexibility in how its technology can be deployed to drive digital transformation – on premises, in the cloud, or via its pure SaaS platform. 

Substantial tissue loss can be the result from different causes, including cancer, injury, and infection. Reconstructive surgery attempts to mitigate the damage. Currently, the clinical “gold standard” in the field of reconstructive surgery is the autograft, which entails harvesting tissue from one part of the patient’s body, and transferring it to the damaged site. For example, to reconstruct the lower jaw, surgeons may harvest a portion of the fibula bone, together with the soft tissue and blood vessels around it, from the patient’s leg. The soft tissue and blood vessels are necessary for the bone to survive in its new location.

As one might imagine, there are significant disadvantages to taking a large chunk out of one’s body, such as considerable pain or all the usual complications associated with a surgery at the donor site. Scientists are therefore looking for alternatives to tissue harvest and moving towards tissue engineering. Although some progress has been made in the field, there are still major challenges to overcome in the search for tissue replacements. The Holy Grail for the scientists is de novo tissue generation. Instead of taking tissues from one part of the body to implant in another, new tissues for implantation would be grown in a lab.

That is where Professor Shulamit Levenberg and her team come in. In the Faculty of Biomedical Engineering at the Technion, the focus of her tissue regeneration lab has been on the formation of complex blood vessel networks in lab-grown tissues. Recently, her team created vascularized soft tissues for implantation using stem cells derived from the dental pulp, that is the soft tissue inside the tooth, together with capillary forming (endothelial) cells. The addition of the dental pulp stem cells promoted the generation of the blood vessels, eventually leading to enhanced tissue remodeling and repair. The new methodology was then used to repair a bone defect in rats, leading to a complete recovery.

. 

As previously mentioned, bone implanted as part of reconstructive surgery would need soft tissues to support it and blood vessels to feed it. In a recent study conducted in Prof. Levenberg’s lab, Dr. Idan Redenski and his colleagues were able to tackle the issue. In findings recently published in Advanced Functional Materials (link), the team put together their own vascularized tissue technology with biological bone implants developed at Columbia University by Professor Gordana Vunjak-Novakovic to create a de novo tissue flap containing live bone supported by vascularized soft tissue. This took the concept of implantable bone tissue to a whole different level.

That, however, was only the first stage. Having shown that a mixed tissue flap can be grown, the team proceeded to use the new methodology to repair a bone defect in rats, using a two-step approach. First, an engineered soft tissue flap was implanted. Once it was integrated into the body of the rat, the engineered flap was exposed in a second surgery and used to repair a bone defect, while being supported by major blood vessels next to the defect site. The decellularized bone was exposed and inserted to correct the existing defect while the engineered tissue flap supported it. The results were a complete success: the soft tissue with the blood vessels supporting and feeding the bone led to bridging of the bony defect, with the rat’s cells growing in and replenishing the implant. It was, in fact, a complete recovery, better than anything reconstructive surgery can achieve, and not based patient tissue harvest.

Returning to the concept of a jaw implant, one can hope that one day, based on the methods developed by Prof. Levenberg, Dr. Redenski, and the rest of the team, it will be possible for the patient to receive a lab-grown bone perfectly matching the shape of their face, surrounded by lab-grown soft tissues based on their own cells cultivated on 3-dimensional biomaterials. No major damage to other parts of the patient’s body would be necessary.

After finishing his Ph.D., Dr. Redenski will begin a residency in oral and maxillofacial surgery at the Galilee Medical Centre, where he plans to continue his research with the hope of taking the methods developed in Prof. Levenberg’s lab and implementing them in the clinic.

The following people took part in this research: Dr. Idan Redenski, Shaowei Guo, Majd Machour, Ariel Szklanny, Shira Landau, Ben Kaplan, Roberta I. Lock, Yankel Gabet, Dana Egozi, Gordana Vunjak-Novakovic, and Prof. Shulamit Levenberg. Special thanks go to Bruker-Skyscan for their assistance with the microCT studies, allowing non-invasive and precise observation of the healing process.
