Sustainable Methods to Extract Micro to Nano Structured Cellulose.

Cellulose is the most abundant, renewable, sustainable biopolymer on the earth. It can be extracted from all types of plant species, bacteria, tunicates, etc. Especially, in plant species, this polymer exists along with other components (e.g., hemicellulose, lignin). All components have their own importance and role in plant structure. Their extraction in individual form can be a platform to develop a wide range of vital chemical moieties for a variety of applications. Our research is mainly focused on the extraction and application of cellulose polymer for advanced applications (water purification and energy storage). For this, our primarily aim is to develop the processes which can not only perform the extraction of cellulose but also its functionalization together in a one-pot. For example: Recently, we have developed a simpler and cost-effective Nitro-oxidation method that can efficiently cause the pretreatment and oxidation of raw biomass together in a one-pot into the nanostructured carboxylated cellulose.  A particular emphasis will be on upcycling the agricultural waste, invasive grasses into the valuable substrates (e.g.: functionalized micro or nano structured cellulose).  

Sustainable Technologies for Water Purification

Membrane technology remains to be the most energy-efficient process to remove contaminants from water. Instead of this, the current membrane technology including the relatively expensive synthetic substrate is often unaffordable and non-sustainable for the bottom-line community in our society.  It is plausible that cellulose-based membranes developed from inexpensive, abundant, and sustainable resources (such as agriculture residues, underutilized biomass waste) can substantially lower the cost of membrane separation.  Our aim is to develop the different strategies to activate and functionalize the cellulose substrate (this research is planned to extend to other natural polymers e.g., chitin, alginates) to create the surficial charge and to enhance the surface area without scarifying its strength for its utilization in primary and secondary steps of water purification. The primary step involves its use as a coagulant/flocculant and the secondary step includes its utilization as a membrane substrate.


Sustainable Nanomaterials in Energy Storage Application

We are interested in finding the appropriate approaches to develop the micro or nanostructured pure cellulose-based membrane or composite membrane for their utilization in proton-exchange fuel cell membranes. The only commercial proton exchange membrane used is Nafion, a fluoropolymer that conducts protons via sulfonic acid groups. Unfortunately, the limitations associated with Nafion include: (i) high cost; (ii) susceptibility to hydrogen gas crossover; (iii) complex recycling process; (iv) loss of performance (proton conductivity and mechanical stability) at a low relative humidity (RH) and high temperature.   Our aim is to develop a biopolymer-based membrane with high proton conductivity, high wet mechanical strength, and high thermal stability. In this direction, this project requires research in chemical modification of polymer and post-treatment of the membrane.
