Overview

Current technological innovations are, to a large extent, connected to materials. Consequently, innovative research tends to seek the characterization of materials through advanced techniques. Material characterization forms the basis for understanding the physical and chemical properties of a material, leading to its potential applications in various domains of science and technology.

Appropriately, the Centre is well equipped with several advanced equipment under a single roof, called Sophisticated Instrumentation Facility (SIF) lab.  The SIF lab houses several spectroscopic, chromatographic, microscopic and thermal instruments as detailed below. It has well experienced operators and subject experts adding value to the facility. This facility is extended to external users.
