Dr. Sharma is a polymer chemist making breakthroughs in the use of untreated biomass (cellulose) – the most abundant natural polymer on earth - to sustainably develop carboxy-cellulose nanofibers. Traditional methods of synthesizing carboxycellulose nanofibers require a pretreatment step that can prove to be quite costly based on the time, energy and reagents required and the waste that is produced as a byproduct of the process. However, Dr. Sharma has developed a novel, efficient, single step Nitro-oxidation process that no longer requires pretreatment of the biomass (weeds, grass, and agricultural waste) in the synthesis of the nanofibers and the byproducts of this nitro oxidation process are useful and can be converted into plant fertilizers. These nanofibers have been shown to be quite effective in water purification. They can remove lead, cadmium and mercury ion impurities from water and have maximum adsorption capacities that rival the best reported adsorbents currently available. Other potential applications include drug delivery, the development of fuel cell membranes and gas barrier films.

"Absolute concentration and persistence lead to solution to the problem."
