Research
Research is conducted in all of the traditional fields of chemistry:
physical, theoretical, organic and inorganic - synthetic and mechanistic,
analytical, biochemical, materials, and environmental.
Multidisciplinary research is carried out both within the Department, and
in cooperation with many of the Technion's other scientific and
technological departments, and with other research institutions.
Special emphasis is given to collaborative projects with leading research
groups worldwide.

For a more detailed picture of the research activities the reader is
referred to the brief biographical sketch of each of our
faculty members,
including a concise outline of their research interests.
The analytical facilities at the Department of Chemistry currently include
the following instruments:
NMR spectrometers: Bruker AV500 and AV300 (AM-400 and AC-200 (two units) still in use)
Fourier transform infrared spectrometer, Nicolet, Impact 400
Gas Chromatograph - Mass Spectrometer (GCMS), Finnigan Magnum
X-ray diffractometer, Phillips, equipped for low temperature
measurements
Differential Scanning Calorimeter (DSC)
Atomic Absorption Spectrophotometer (AAS), flame and furnace
The National Center for Mass Spectrometry, which is situated in the
Department of Chemistry, operates the following instruments:
an ion trap GCMS (Finnigan ITS 40)
a triple quadrupole mass spectrometer (Finnigan TSQ-70B)
with various ionization modes
a double focusing high resolution mass spectrometer
(Varian-MAT 711)
These capabilities are complemented by two modern research laboratories,
the first for the crystallography of proteins (operating a Rigaku
R-Axis IIC X-ray diffractometer), and the second comprising a fully
equipped triple-resonance solid state NMR spectrometer (Chemagnetics
Infinity 300-MHz).
Due to the increasing importance of environmental related issues a
modern research laboratory has been established recently.
This laboratory consists of: Laser Plasma Spectroscopy (LPS),
Resonance Enhanced Multiphoton Ionization (REMPI), Reflectron Time of
Flight Mass-Spectrometer (RTOF-MS), Portable Gas Chromatograph,
Time Resolved Laser Induced Fluorimeter (TR-LIF) and other novel
electroanalytical systems.
In recent years the Department of Chemistry has acquired modern equipment
for advanced research
in the fields of solid-state and of surface chemistry and physics.
The laboratories of surface chemistry and physics consist of:
a scanning probe microscope for the studies of physical and
chemical properties of surfaces with nanometer resolution
FTIR spectrometer for IR studies of solid surfaces and adsorbates
AES, LEED, and TPD facilities for the investigation of adsorption
and other physico-chemical properties of surfaces
an apparatus for hyperthermal molecular beam - surface scattering
and thin film growth hemispherical electron energy analyzer for surface
characterization by Auger and Electron Energy Loss (EEL) spectroscopies
In addition, we have at our disposal research facilities at an adjacent
building, the Solid State Institute (SSI), consisting of: facilities
for ion implantation and ion beam analysis, equipment for surface studies
by means of electron spectroscopy and secondary ion mass spectrometry,
equipment for evaluation of semiconductor devices and crystal growth.
Several members of the academic staff of the Chemistry Department have
established research laboratories at the SSI in the areas of optical
spectroscopy and surface science.
Various research groups in the Department study chemistry by lasers,
utilizing them in a broad range of applications. Several powerful pulsed
Nd:YAG lasers are available (up to 220MW/cm2), as well as N2
lasers (up to 2.5MW/cm2) and an Excimer laser. Some are equipped with
harmonic generators and dye units for tuning the output wavelength.
The available spectroscopic systems include classical and imaging
spectrometers equipped with photomultipliers, Charged Coupled Devices
(CCD's), Intensified Photodiode Array (IPDA) and Intensified CCD (ICCD) as
detectors. These systems are utilized for molecular systems in solution
and in supersonic molecular beams. Also available is a modulated beam
mass spectrometer for studies of decay processes in isolated gas-phase
molecules. A magneto-optical spectrometer which combines cryogenic systems,
CW lasers, optical accessories and magnetic fields is utilized for studies
of solid-state materials and devices.
An industrial Near Infra Red (NIR) spectroscopic system is also available
as well as a portable (PC plugged in) UV-Visible fiber optical
spectrometer for environmental applications.
Several advanced research laboratories focus on synthetic organic,
inorganic, organometallic and catalysis chemistry. Gloveboxes, schlenk
lines, high vacuum lines, greaseless vacuum lines, cryogenic spectrometry
equipment, and cryoscopic molecular weight equipment for air-sensitive
materials comprise some of the available equipment in these laboratories.
Several research laboratories in the Department focus on biology-oriented
projects. Specialized equipment present in these laboratories includes
fully computerized FPLC and HPLC protein purification systems, lyophilizer,
spectrophotometers, electrophoresis apparatus, X-ray diffractometer for
for large molecules, triple-resonance solid-state NMR spectrometer,
incubators, shakers, cold rooms and other equipment required for cell
growth, purification and analysis of proteins.
Located in close proximity, the Departments of Biology and of Food
Engineering & Biotechnology offer supplementary facilities to the Chemistry
Department for work on biology-oriented projects.
This equipment includes: a variety of low- and high-speed centrifuges,
high-speed ultracentrifuges, fully computerized FPLC and HPLC protein
purification systems, fully computerized fermenters (2, 10 and 50 liters),
incubators, ultra low temperature freezers and more.
The cutting-edge National Center for Protein and Peptides Microanalysis
situated at the Department of Biology, offers the following services:
sequencing, internal and external radioactive sequencing,
mass spectrometry of proteins and peptides, synthetic peptides, libraries
of proteins and peptides, 2D-gel electrophoresis, database searches and
analysis. Several faculty members of the
Chemistry Department are associated with this center.
The Department of Chemistry is one of the most active in the Technion in
scientific computing and as such is a major consumer of the services of the
Technion's central computer facilities, which include parallel computers
(Silicon Graphics Power Challenge and a 8-processor
Dec Alpha server) as well as several other powerful Unix stations.
Large-scale computation may be performed in the recently established
National Supercomputer Center, which offers access to two different
supercomputers (Cray J932 and IBM SP2).
The Departmental Computer Center is equipped with 4-processor DEC
Alpha Server 4100 5/466, two Dec Alpha 600 5/266
workstations, and three DEC Ultrix workstations.
Nine Silicon Graphics work-stations and dozens of X-terminals and
personal computers are also available. Every office and laboratory in the
department is connected via Ethernet to the Technion Local Area Network
(LAN) and to the national and international networks and databases.
The
Minerva Center for Computational Quantum Chemistryi,
recently established in the Department of Chemistry, includes advanced
computers, state-of-the-art computational software packages and other
resources to support research in this fast-developing field of chemistry.

The technical services are organized into well-equipped mechanical,
electronic and glass-blowing units, as well as a support group for
computer-related activities. These units are staffed by highly
skilled engineers and technicians, who are responsible for all of the
technical work carried out within the department. This includes the
design and construction of new instrumentation, as well as
maintenance of all scientific equipment.
The Chemistry and Biology Library is located in the Chemistry Department
Building. The library owns the complete collection of Chemical Abstracts,
Beilstein and Gmelin as well as numerous encyclopedias, collective series
and books.
The library subscribes to more than 220 periodicals and owns a large
collection of books dealing with a broad spectrum of topics in
chemistry, biology, environmental science and related fields.
A variety of on-line search services are available.
