Item Biodegradable and Biocompatible Polymeric Materials for Dentistry Applications(wiley, 2022) Pallavi, K.C.; Isloor, A.M.; Rao, L.N.The ongoing review assembles particulars regarding the diverse biodegradable polymeric materials, also which are specified by sole criteria of biocompatibility that are utilized for diagnosis and treatment needed in dentistry. Natural polymeric substrates are conjunct with various other bioactive molecules or polymers, which strikes off limitations of the former yielding an emerging composite modeled to attain the form of encapsulated microspheres, hydrogels, membranes, nanofibers, and scaffolds. The sustainability of particular polymeric material in the biomedical stream such as dentistry is decided by evaluating aspects, such as the extent of immunogenicity on employing, degradability time versus functionality time, noncytotoxicity, and performance on respective treatment. Enormous materials have been modeled, which have proven their viability in treating dental conditions, like chronic periodontitis, microbial attacks like bacterial and fungal infections, and bone deterioration, also in the controlled discharge of oral drugs. © 2022 Scrivener Publishing LLC.Item Biopolymeric Nanofibrous Materials for Environmental Remediation(wiley, 2022) Pallavi, K.C.; Isloor, A.M.The present content gathers information regarding the use of nanofibrous materials fabricated out of biopolymers in environmental problems. Biopolymers are environment-friendly and nonhazardous in character. Various conventional methods have been employed so far to solve problems, such as water pollution, air contamination, and soil infertility. Membranes of different types, filtration systems, and various sorbents have been found useful in the removal of contaminants. Apart from all those, nanofibrous materials attain great importance due to their noncomparable high surface area, minute pore size, diameter in the nanorange, and good adsorptive property. Nanofibers can be fabricated out of diverse polymers through various techniques, such as electrospinning. The surface modifications, such as chemical grafting and oxygen plasma treatment induced functional group insertion, can be done, which imparts high potential in respective applications. The present review chapter describes about nanofiber fabrication technique, properties of the resultant nanofiber mat, and their importance in environmental remediation, such as removal of airborne and waterborne contaminants. © 2022 Scrivener Publishing LLC.Item Nonporous polymeric membranes for biohydrogen purification(Elsevier, 2025) Mendonca, N.R.; Isloor, A.M.; A.F., A.F.Biohydrogen generated from biomass is a clean form of hydrogen. The dark fermentation process for the generation of biohydrogen gives a mixture of H2 and CO2 from which biohydrogen needs to be purified. From the available methods for biohydrogen purification, membrane technology is the most viable since it is less energy-intensive and can be combined easily with other processes. Both polymeric as well as inorganic membranes are employed in gas separation processes. Of these, nonporous polymeric membranes are economically viable and are hence used in large-scale gas separations. The use of nonporous polymeric membranes, composed of polymers like polybenzimidazole, polyimide, and polysulfone, for biohydrogen purification is an ongoing area of research which can help to generate hydrogen for use in hydrogen fuel cells, hence reducing the dependence on fossil fuels which pollute the environment. © 2026 Elsevier Inc.
