Membrane science: Advancements in Polymer-based membranes for water remediation, the advanced membrane engineering, and science that underlie the separation procedures used in polymer-based composite membrane systems for water remediation. The emphasis has been put on the reduced pressure- and potential-driven membranes, updated with the most recent technological advancements, pertinent polymer materials, and application potential towards sustainable water treatment systems for resolving the global urge.
Energy storage:
Merging the benefits of individual developments of different electrode materials with an intense focus on their precursors and synthesis strategy. While putting efforts to improve supercapacitors to stretch their performance to better them in case of energy density and stability. The research focus includes the electrode materials which are low-cost, less-toxic, and conductive materials maintaining their, structural and morphological stability is found to be challenging still which of course affects the stable capacitance numbers, energy density and cyclic stability as well.

Capacitive Deionization (CDI): Desalination of saline or seawater, which is abundant on earth, has been established as a reliable method of creating fresh water. Due to its low energy consumption, low maintenance costs, and environmental friendliness, capacitive deionization (CDI) is a new technology for the simple removal of charged ionic species from aqueous solutions, including water desalination. The method is based on the surface of two electrically charged electrodes, which are typically made of very porous carbon materials, being electrosorbed by ions. Over the past ten years, the CDI community has evolved dramatically, propelling enormous advancements through new cell topologies and system designs.
Membrane Science: Jyothi M S & Vignesh
Focus is on desalination, brackish water treatment and removal of heavy and toxic metal ions. This extends the research towards preparation of nano and ultra filtration membranes, amphiphilic polymers and chemical modification of polymers, composites and blends, insertion of nanoparticles into membrane matrix and surface modification of membranes by chemical and physical methods. In this pursuit better diagnostic tools, methods, models and designs towards advanced membrane materials for improved performances like antifouling, antimicrobial, reduced cost and mitigation of its environmental impact, associated with water purification are explored. The ion exchange membranes for the dialysis and fuel cells, remediation of oil contaminated waters are our future research targets.
