    An important technological solution for plastic pollution is the replacement of traditional biodegradable polymers, biodegradable polymer materials with physico-mechanical properties that cause environmental pollution. An urgent problem is the search for ways to reduce the self-decomposition of biopolymers and waste, as well as to reduce the cost of such materials, including the use for these purposes of substances that can be analogues of biodegradable polymers. The research work is aimed at obtaining a biodegradable biopolymer based on starch raw materials in the presence of various organic acids (citric acid, acetic acid, lactic acid) and plasticizers (glycerin, polyvinyl alcohol, nanomaterial). An effective material was selected from the products obtained from various acids and plasticizers. Measures to improve the technology of bioplastics production are considered. A durable and economical biopolymer capable of processing and biodegrading biological waste, including starch-containing garbage, has been obtained. The resulting products have successfully passed all physico-chemical tests and are ready for mass production. A scanning electron microscope and thermogravimetric analysis with IR spectroscopy were used to study the physicochemical parameters of the obtained biopolymers.

    This study explores the production of microcrystalline cellulose (MCC) through delignification of agricultural biomass and investigates its physicochemical properties.Rice husks and wheat straw served as primary biomass sources.The influence of the biomass-to-peroxyacetic acid ratio on MCC yield was systematically evaluated, with optimal yields of 70% from wheat straw and 85% from rice

    MXene derivatives and composites are becoming fresh and promising two-dimensional (2D) materials because of their unique properties, performance, and multifunctionalities.This review covers the general aspects of MXenes (family of 2D transition metal carbides, nitrides, and carbonitrides), their MAX phase (a diverse class of nanolaminate materials with intriguing properties that have received incredible global research attention because they bridge the divide separating metals and ceramics.)precursors, dissimilarities and similarities between MAX phases and MXenes, and special properties of both materials.The important focuses are made on the methods of MXene synthesis and their stability and conductivity, as well as on synthesizing new MXene composites with desired characteristics.The impacts of MXenes in energy storage systems, especially supercapacitors, are discussed based on the high specific surface area, tunable porosity, and optimized inter-layer spacing.Here, various aspects of MXene materials, including properties, synthesis, and applications, have been discussed to highlight their importance for the development of energy storage systems and material science research.
