Abstract Global water pollution is becoming increasingly serious, and compound pollutants such as heavy metals and organic dyes pose multidimensional threats to ecology and human health. Metal-organic skeleton compounds (MOFs) have been proven to be highly efficient in capturing a variety of pollutants by virtue of their large specific surface area, adjustable pore channels, and abundant active sites. However, the easy agglomeration of powders, the difficulty of recycling, and the poor long-term stability have limited their practical applications. Cellulose, as the most abundant renewable polymer in nature, has the characteristics of a three-dimensional network, mechanical flexibility,… More >

Abstract The pursuit of safer energy storage systems is driving the development of advanced electrolytes for lithium-ion batteries. Traditional liquid electrolytes pose flammability risks, while solid-state alternatives often suffer from low ionic conductivity. Gel polymer electrolytes (GPEs) emerge as a promising compromise, combining the safety of solids with the ionic conductivity of liquids. Cellulose, an abundant and eco-friendly polymer, presents an ideal base material for sustainable GPEs due to its biocompatibility and mechanical strength. This study systematically investigates how drying methods affect cellulose-based GPEs. Cellulose hydrogels were synthesized through dissolution-crosslinking and processed using vacuum drying (VD),… More >

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 The development of the bioplastics industry addresses critical issues such as environmental pollution and food safety concerns. However, the industrialization of bioplastics remains underdeveloped due to challenges such as high production costs and suboptimal material characteristics. To enhance these characteristics, this study investigates bioplastics reinforced with Nanocrystalline Cellulose (NCC) derived from Oil Palm Empty Fruit Bunches (OPEFB), incorporating dispersing agents. The research employs a Central Composite Design from the Response Surface Methodology (RSM) with two factors: the type of dispersing agent (KCl and NaCl) and the NCC concentration from OPEFB (1%–5%), along with the dispersing… More >

Abstract The global demand for renewable and sustainable non-petroleum-based resources is rapidly increasing. Lignocellulosic biomass is a valuable resource with broad potential for nanocellulose (NC) production. However, limited studies are available regarding the potential toxicological impact of NC. We provide an overview of the nanosafety implications associated mainly with nanofibrillated cellulose (CNF) and identify knowledge gaps. For this purpose, we present an analysis of the studies published from 2014 to 2025 in which the authors mention aspects related to toxicity in the context of packaging. We also analyze the main methods used for toxicity evaluations and… More > Graphic Abstract

Abstract Polymeric materials have emerged as a promising alternative to electrolytic solutions in energy storage applications. However, high crystallinity and poor ionic conductivity are the main barriers restricting their daily application. In this study, we propose a polymer electrolyte system consisting of methylcellulose-polyvinyl alcohol (MC-PVA) blend as host material and lithium trifluoromethanesulfonate (LiCF₃SO₃) as dopant, which was prepared using the solution-casting method. The electrochemical impedance spectroscopy (EIS) analysis revealed a maximum conductivity of 5.42 × 10⁻⁶ S cm⁻¹ with 40 wt.% LiCF₃SO₃. The key findings demonstrated that the variation in the dielectric loss (ε_i) and dielectric constant (ε_r) was… More >

Abstract Agricultural waste is a potentially interesting resource due to the compounds present. In this study, cellulose was extracted from corn stalks (Zea mays) and subsequently converted into cellulose acetate (CA). Before the extraction process, the waste sample was characterized by pH, moisture, ash, protein content, total reducing sugars (TRS), carbohydrates, cellulose, hemicellulose, and lignin. Acid and alkaline hydrolysis were performed with different reagents, concentrations, and extraction times. Sulfuric acid (H₂SO₄) and acetic acid (CH₃COOH) were used in the acid hydrolysis, while sodium hydroxide (NaOH) was used in the alkaline hydrolysis. Three concentrations (0.62, 1.25, 2.5)% and two… More >

Abstract Under the background of the current energy crisis and environmental pollution, the development of green and sustainable materials has become particularly urgent. As one of the most abundant natural polymers on earth, cellulose has attracted wide attention due to its green recycling, sustainable development, degradability, and low cost. Therefore, cellulose and its derivatives were used as the starting point for comprehensive analysis. First, the basic structural properties of cellulose were discussed, and then the extraction and utilization methods of cellulose were reviewed, including Sodium Hydroxide based solvent system, N, N-Dimethylacetamide/Lithium Chloride System, N-Methylmorpholine-N-Oxide (NMMO) system, More > Graphic Abstract

Abstract In this study, Opuntia ficus-indica cladode powder (OFIC), locally sourced from Rabta in Tunis, was utilized as a novel, eco-friendly adsorbent in both raw and iron(III) chloride-modified forms. The presence of iron in the modified material was confirmed by X-ray fluorescence spectroscopy (XRF). The neat and modified biomass were characterized by X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM), and their usefulness as adsorbent for cationic Neutral Red (NR) and anionic Congo Red (CR) dyes were explored under batch conditions. Equilibrium studies revealed that the iron-modified Fe(OH)_x@Cellulose adsorbent exhibited… More > Graphic Abstract
