PROFESSIONAL AND RESEARCH EXPERIENCES (1994-2005)

 

·          Carried out research towards Ph.D in the field of Nanostructured Materials from School of Pure & Applied Physics, Mahatma Gandhi University, Kottayam, India under the guidance of Dr. M Abdul Khadar, Professor, presently at Department of Physics, University of Kerala, Thiruvananthapuram. The broad area of research includes the synthesis and characterization of nanoparticles and nanocomposites.

 

·                   Presently, working as Scientist in Centre for Materials for Electronics Technology (C-MET). Current areas of research include the preparation and characterization of nanomaterials , development of polymer ceramic microwave substrates, new ceramic compositions for capacitor applications, development of polymer-ceramic nanocomposites.

 

·                   Developed translucent nanoporous silica aerogels through supercritical drying. An autoclave is designed and indigenously fabricated for the supercritical drying of alcogels. Highly porous translucent aerogels were prepared through a new composition which is under the process of patenting.

 

·                 Well-versed in operating X-ray diffractometer, Mercury Porosimeter, Microhardness Tester, Impedance Analyser, Ultrasonic velocity measurements, TGA/DTA, Microprocesser controlled muffle furnaces etc. Got experience in the alignment and operation of high temperature camera for carrying out temperature dependent structural studies, and gracing angle incidence set up for thin film samples.

 

·                   Investigated the impedance spectroscopic analysis of certain inorganic nanostructured materials and nanocomposites, and studied the grain and grain boundary effects to the electrical conductivity.

 

·                 Awarded DST Fast Track Research Project for Young Scientists in 2005.  The title of the project is Development of polymer-ceramic nanocomposite solid electrolytes for electronic applications.

 

·                 Awarded KSCSTE Young Scientist Award in Physical Sciences in 2006.

 

·                 Worked as Visiting Scientist at the Royal Institute of Technology, Stockholm and got experience in pulse laser deposition of thin films.
