“Chemical methods for synthesis of Nano-Particle sized powders”

He is an alumnus of 1971 batch. Prof. Anil Mishra, Head of the Chemistry Department welcomed the guests. He mentioned that such alumni lectures is a boon to the department of chemistry as it provides newer insights into the understanding of varied area of Chemistry to research scholars and faculty members.

He mentioned that this lecture will provide an in-depth understanding of the chemical methods for synthesizing nano-sized powders, focusing on the principles, processes, advantages, limitations, and applications of each technique.Dr. Chandra was introduced to the audience by Dr. Vinod and a memento was given to him by Prof. Abha Bishnoi . 

In his lecture on “Chemical methods for synthesis of Nano-Particle sized powders” Dr. Chandra described various chemical methods used for the preparation of nano sized inorganic powders with illustrations based mostly on the research work done by his research group at CSIR-Advance Materials and Products Research Institute, Bhopal. 

The characteristics of nano sized materials are presented followed by preparation of various metal oxides (manganese oxide, zirconium oxide, titanium dioxide, iron oxide, indium oxide etc.), metal carbides (titanium carbide, zirconium carbide, tungsten carbide etc.) and CdS, using controlled precipitation/aqueous sol-gel/emulsion/solvothermal/solvent-antisolvent and combustion methods. The methods for characterization of synthesized nano powders include powder X-ray diffraction, FTIR, UV-Visible spectrometry, HRSEM and HRTEM. 

For curious audience preparation of nano-sized powders of organic compounds such as curcumin, norfloxacin etc. by solvent-anti solvent method and nano sized silver and gold particles using bio-route were also presented.
Dr. Priyanka Pandey proposed the vote of thanks. The program was attended by all the faculty members and research scholars of the department.
