Rechargeable Silicon Batteries – Sustainable Energy Source
A team of researchers from the Technion – Israel Institute of Technology has developed a proof-of-concept for a novel rechargeable silicon (Si) battery, as well as its design and architecture that enables Si to be reversibly discharged and charged. Led by Professor Yair Ein-Eli of the Faculty of Materials Science and Engineering, the team proved via… Read More
How corals, starfish build their “skeleton”
How do marine organisms produce hard tissues from the materials available to them, and under the hostile conditions that prevail under the waves? That question is the basis of a study by an international group led by Professor Boaz Pokroy, doctoral student Nuphar Bianco-Stein (as part of her Ph.D. thesis), and researcher Dr. Alex Kartsman… Read More
Self-Repairing Electronics Are on the Way
From the Terminator to Spiderman’s suit, self-repairing robots and devices abound in sci-fi movies. In reality, though, wear and tear reduce the effectiveness of electronic devices until they need to be replaced. What if the cracked screen of your mobile phone could heal itself overnight? Or, if the solar panels providing energy to satellites could… Read More
We’re Losing Oxygen, and It’s Great!
What do ultrasound imaging of a fetus, cellular mobile communication, micro motors, and low-energy-consumption computer memories have in common? All of these technologies are based on ferroelectric materials, which are characterized by a strong correlation between their atomic structure and the electrical and mechanical properties. Technion – Israel Institute of Technology researchers have succeeded in… Read More
Defects in Gold as a Template for Nanowire Growth
Technion researchers have presented an innovative method for the formation of nanowires. In it, the nanowires form within line defects that exist in metals. Such defects are known as dislocations. This is the first time that dislocation lines in a material of one kind serve as a template for the growth of a different inorganic… Read More
No Batteries? No Problem
Energy & Environmental Science has reported a scientific breakthrough in the study of hematite, an important and promising material in the conversion of solar energy into hydrogen through photoelectrochemical water splitting. The research project was headed by Professor Avner Rothschild of the Faculty of Materials Science and Engineering at the Technion – Israel Institute of… Read More
Fast-Charging Batteries
Fast charging is considered to be a key requirement for widespread economic success of electric vehicles. Current lithium-ion batteries (LIBs) offer high energy density, but while they enable sufficient driving range, they take considerably longer to recharge than traditional vehicles. Multiple properties of the applied anode, cathode, and electrolyte materials influence the fast-charging ability of… Read More
