General description

Glassy carbon shows only short range order in its structure. Photoacoustic doppler effect from the suspension of spherical carbon particles was investigated. Glassy carbon exhibits a specific conductivity of 700Scm-1. 4

Application

Amorphous carbon may be used to develop zero temperature coefficient of resistance (TCR) based systems. Glassy carbon has been used as a catalyst support for bimetallic Rh–ReOx. It may be used to enhance the accuracy of infrared (IR) surface temperature measurements on micro-electro-mechanical systems (MEMS).

Recent demand for electric and hybrid vehicles, coupled with a reduction in prices, has caused lithium-ion batteries (LIBs) to become an increasingly popular form of rechargeable battery technology.

Solid oxide fuel cells (SOFC) and solid oxide electrolyzers (SOE) are in the early stages of development; however, the performance that has been achieved shows promise for conversion between chemical and electrical energy.

Li-ion batteries are currently the focus of numerous research efforts with applications designed to reduce carbon-based emissions and improve energy storage capabilities.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
