Condensed Matter Research Lab – Bannari Amman Institute of Technology

Condensed Matter Research Laboratory (CMRL) is well established Liquid Crystal Research Lab under the Department of Physics, Bannari Amman Institute of Technology, Sathyamangalam. CMRL consists of sophisticated instrument such as Polarizing Optical Microscope (POM) attached with SONY CCD camera, Differential Scanning Calorimetry (DSC 60Plus), Impedance analyser, etc., This lab had been equipped with help of central Govt. funding agencies (DST, DAE-BRNS) and BIT management. CMRL has been effectively utilized by PhD, BE, B.Tech M.SC and M.Phil students to enhance their knowledge by doing research activities. In CMRL, different kinds of hydrogen bonded liquid crystals are designed, synthesized and characterized for optoelectronic device applications. As a project investigator, Dr V N Vijayakumar/AP Level III/Physics is appointed as CMRL incharge and encompassing with different research activities by publishing more than 60 research articles in various peer reviewed international journals (Elsevier, Springer, Taylor & Francis etc).
