Abstract The valorization of plant biomass towards high-value chemicals is a global trend aimed at solving the problem of the huge accumulation of lignocellulosic waste. Plant polysaccharides are natural polymers that make up about 20% by weight of biomass, with a unique variety of structures and properties that depend on the type of raw materials and the method of their extraction. In this study, the effect of variability of the oxidative delignification process conditions in the «acetic acid-hydrogen peroxide-water-(NH₄)₆Mo₇O₂₄» on the extraction and properties of aspen (Populus tremula) wood hemicelluloses was investigated for the first time. The developed… More > Graphic Abstract

Abstract Nanocellulose, derived from abundant lignocellulosic biomass, has emerged as a transformative material with unparalleled versatility across industries. This review systematically analyzes its sources, extraction methods, and multidimensional applications. Key findings include: (1) Plant fiber hierarchy dictates nanocellulose properties, with wood-derived cellulose offering high crystallinity and agricultural waste enabling cost-effective production. (2) Acid hydrolysis remains dominant for cellulose nanocrystals (CNCs), while mechanical methods yield high-aspect-ratio cellulose nanofibrils (CNFs). (3) Nanocellulose’s mechanical strength, biocompatibility, and tunable surface chemistry drive innovations in energy storage (e.g., supercapacitors), biosensors (e.g., glucose monitoring), and biomedical engineering (e.g., 3D-printed scaffolds).

Abstract In recent decades, the ozone layer has suffered considerable damage, increasing the entry of ultraviolet (UV) light into the atmosphere and reaching the earth’s surface, negatively affecting life. Accordingly, researchers aimed to solve this problem by synthesizing advanced UV-shielding materials. On the other hand, developing an easy and green strategy to prepare functional materials with outstanding properties based on naturally abundant and environmentally friendly raw materials is highly desirable for sustainable development. Because biomass-derived materials are sustainable and biodegradable, they present a promising substitute for petroleum-based polymers. The three main structural constituents of the plant More > Graphic Abstract
