(Royal Society of Chemistry, 2023-04-20) Chincholikar, Preeti; Singh, Kshitij RB; Natarajan, Arunadevi; Kerry, Rout George; Singh, Jay; Malviya, Jitendra; Singh, Ravindra Pratap
To minimize the usage of non-renewable resources and to maintain a sustainable environment, the exploitation of green nanobiopolymers should be enhanced. Biopolymers are generally developed from various microorganisms and plants in the specified condition. This review article discusses the current advances and trends of biopolymers, particularly in the arena of nanotechnology. In addition, discussion on various synthesis steps and structural characterization of green polymer materials like cellulose, chitin, and lignin is also encompassed. This article aims to coordinate the most recent outputs and possible future utilization of nanobiopolymers to the ecosystem with negligible effects by promoting the utilities of polymeric materials like polycaprolactones, starch, and nanocellulose. Additionally, strategic modification of cellulose into nanocellulose via rearrangement of the polymeric compound to serve various industrial and medical purposes has also been highlighted in the review. Specifically, the process of nanoencapsulation and its advancements in terms of nutritional aspects was also presented. The potential utility of green nanobiopolymers is one of the best cost-effective alternatives concerning circular economy and thereby helps to maintain sustainability.

MXENES-BASED BIOSENSORS
(Wiley, 2024-01-01) Thapa, Sushma; Singh Kshitij, R B; Natarajan, Arunadevi; Kerry, Rout George; Singh, Jay; Pandey Shyam, S; Singh, Ravindra Pratap
MXenes are recently developed two-dimensional (2D) inorganic compounds with few atomic layers that have exceptional properties, for instance, thermal, magnetic, optical, electronic, and mechanical. Owing to their excellent properties, chemical composition, and layered structure, MXene is one of the prime materials for the advancement of biosensors, among other latest nanomaterials. Fabricating advanced biosensors with high selectivity and sensitivity is one of the most required concerns in biosensors. Numerous nanomaterials, including MXenes, have been introduced to fabricate biosensors for obtaining high selectivity and sensitivity. Therefore, in this book chapter, advanced biosensors were discussed based on 2D MXene for biomedical, agricultural, and environmental remediation applications

SYNTHESIS AND ADVANCES OF SMART HETEROATOM-SITED COATINGS FOR ANTICORROSION APPLICATIONS (Article)
(Taiwan Institute of Chemical Engineers, 2025-01) Swathika, M; Chandran, Sharmila; Singh Kshitij, RB; Singh, Ravindra Pratap; Pandey Shyam, S; Natarajan, Arunadevi
Recently, there has been a significant interest in nanocomposites with porous structure, excellent thermal stability, and stiffness. The corrosion resistance behavior of epoxy resin-based Ni and Co metal oxides nanocomposite is reported here. The anti-corrosion abilities of mild steel substrates were investigated in different media like bore water, soil, and bacteria. Over 120 days, the inhibitory efficiency of the target compound was tested.The corrosion process was studied under a UV chamber at different wavelengths at 254 nm, 365 nm, and at visible region respectively. The bacterial study was carried out against the gram (+) and gram (-) on the mild steel specimen against Staphylococcus aureus and Escherichia coli. Morphological studies show the effective nanocomposite encapsulation in epoxy resin. The powder XRD method divulges the structure, and the dispersity of the epoxy layer as projected by scanning electron microscopy. Anti-corrosion properties were determined by electrochemical impedance spectroscopy (EIS) and polarization methods.The results display nano CoO has improved anti-corrosion characteristics compared to nano NiO. The metal nano coating effectively protects mild steel due to barrier properties towards ions responsible for rusting, demonstrating its appropriateness as a next-generation anti-corrosive coating for a sustainable environment.
