Mathematics and Physics Department
Facilities
The department has excellent research laboratory facilities for investigations
of electric and magnetic properties of materials. Active research is pursued
by the faculty in the areas of Syngas Conversion Catalysts, Magnetic Thin
Tilms, Hydrogen Separation/Storage Materials, Nonoparticles and Nanocomposites,
Polymers, Corrosion and Wear Inhibition Coatings, Atmospheric Space Science,
to name a few, using several experimental techniques such as Vibrating Sample
Magnetometer (VSM), Superconducting Quantum Interface Device (SQUID) Magnetometer,
Nuclear Quadrupole Resonance / Zero Field NMR, Positron Annihilation Spectroscopy,
Scanning Electron Microscopy, Energy Dispersive X-ray Spectroscopy, Mossbauer
Spectroscopy, X-ray Diffractometry, Scanning Tunneling Microscopy, FTIR
and UV/VIS spectroscopy, and Laser spectroscopy.
