First Raman spectrum of Uranium
Dr. Ravindran's recent work on Uranium following its publication in J. Raman Spectroscopy and in IGC-NEWS received wide spread attention of the electronic media.
Congratulations to Dr. Ravindran & his colleagues.
Micro cantilever based sensors
Micro-cantilevers are the most simplified MEMS based device and finds wide range of applications for sensing by detecting changes in cantilever bending or vibrational frequency. Our colleagues did extensive design and simulation of a nano cantilever based mass sensor using Intellisuite - A FEM based CAD tool. Using vibrational mode simulations for a poly silicon nano cantilever they found that the sensitivity of a nano cantilever based mass sensor is highly dependent on the area and the position of the loaded mass and higher modes always gives a better sensitivity.
First-Principles Study of Ground-State Properties and Phase Stability of Vanadium Nitrides
Using a series of density functional electronic structure total energy calculations, Our Colleagues have systematically studied the ground-state properties and phase stability of vanadium nitrides.

Stability of cesium loaded iron phosphate glass : an FTIR study
Currently phosphate glasses are being explored as a potential matrix for high level nuclear waste immobilization owing to their higher waste loading capacity and lower processing temperatures although they exhibit poor chemical durability compared to that of the silicate glasses. Our recent work using FTIR to probe the Iron Phophate glass is highlighted here.
Synthesis and Characterization Of Monolithic Ti1-xAlxN Coatings
TiN and Ti1-xAlxN metastable thin films were synthesized by reactive magnetron co-sputtering technique by our colleagues to explore hard multilayer coatings. maximum hardness of 35 GPa and 38 GPa for as deposited and annealed specimens were achieved.
