Research Projects

Exploring vitrification for the management of Li-ion battery materials

Research deals with exploring the potential of vitrification for managing cathode active materials from Li-ion batteries for producing glasses with potential for different applications. The research ultimately aims for evaluating the route for repurposing cathodes wasted from the spent batteries.

Glasses for applications in optical devices

The synthesis and characterization of novel doped glasses with potential for applications in various photonic applications such as light-emitting devices (LEDs), optical filters, spectral conversion in solar cells, lasers and displays is pursued. Further contemplated is the ability of the glass specimens to embed phosphors or incorporate luminescent nanocrystals/quantum dots for LED and display applications.

Understanding gamma-ray irradiation effects in glasses

Borosilicate glass has been adopted internationally for the treatment of nuclear waste with the object of stabilizing the waste through vitrification for long periods of time encompassing thousands of years. This project, in collaboration with the Savannah River National Lab (SRNL, Aiken, SC), aims to develop an in-depth knowledge of spectroscopic properties of the glass forms, and understand broadly light-matter interactions including the effects of high-energy photons from gamma rays. In addition, the functionalization of doped glasses via gamma irradiation is pursued as a novel approach for producing optical materials for various applications in a reductant-free approach.

Structure-property relationship in glasses with various functionalities

The synthesis and comprehensive characterization of glassy materials with functionalities extending from optical materials to biological applications (e.g., bone tissue regeneration) is pursued. The focus is on increasing current understanding of material properties with respect to the composition-structure-property relationship in connection with various applications in materials science and engineering.
