Abstract With the increasing emphasis on green, low-carbon, and sustainable development in shale gas drilling fluids, the utilization of waste biomass resources to develop high-performance drilling fluid additives has emerged as an important research direction that balances engineering requirements with environmental responsibility. In this study, waste cotton–derived polyanionic cellulose (bio-PAC) was employed as the base material, and sulfonate and carboxylate functional groups were introduced via free-radical graft copolymerization to synthesize a modified cellulose polymer, PAC-g-(sodium vinyl sulfonate, SVS/sodium methallyl sulfonate, SMAS/methacrylic acid, MAA). Structural characterization confirmed the successful grafting of the target functional groups onto the… More >

Abstract It takes centuries for chemically reinforced, short-term designed plastics to decompose naturally. Despite this, there has been a significant surge in plastics production recently, accounting for a considerable part of the total historical output. Forecasts indicate that plastics production could reach unprecedented levels if this trend continues. However, increasing environmental concerns and stricter waste regulations have intensified research into biodegradable alternatives. As a result, there is a growing shift toward sustainable polymeric systems capable of replacing conventional petroleum-based plastics. One such class of promising and renewable materials is cellulose-chitosan bioplastic. This review provides an in-depth… More > Graphic Abstract

Abstract Cellulose-based materials have emerged as promising biomaterials for advanced water remediation technologies due to their bioavailability, non-toxicity, biocompatibility, hydrophilicity, and ease of chemical modification. Cellulose can be prepared in multiple forms, including nanomaterials such as cellulose nanofibrils (CNFs), cellulose nanocrystals (CNCs), and electrospun nanofibers. The abundant surface functional groups, such as hydroxyl and carboxyl groups, enable chemical tailoring, grafting, and composite formation with organic and inorganic additives, including metal–organic frameworks (MOFs), carbon-based materials, and metal oxide nanoparticles. These modifications enhance pollutant removal through adsorption, catalysis, and antimicrobial activity, enabling the treatment of heavy metals, dyes, More >

Abstract Oil palm trunks (OPT), abundantly available during plantation replanting, represent a renewable lignocellulosic resource for sustainable material applications. Although OPT-derived cellulose has been extensively explored, the influence of oil palm age on cellulose properties remains insufficiently understood. In this study, cellulose was isolated from OPT aged 21, 25, and 32 years and characterized by scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). SEM observations indicated more uniform and better-separated fibril structures in cellulose from older OPT, suggesting more effective removal of non-cellulosic components. FTIR confirmed successful cellulose isolation More > Graphic Abstract

Abstract The growing threat of viral pandemics necessitates innovative antiviral strategies that are effective, sustainable, and scalable. This review highlights nanocellulose as a renewable, biocompatible nanomaterial and a promising multifunctional antiviral platform. We examine cellulose nanocrystals, nanofibrils, and bacterial nanocellulose, emphasizing their synergistic antiviral mechanisms, including nanoscale viral entrapment and surface-mediated inactivation via sulfation, cationic groups, and metal nanoparticles. Key advances include photothermally active nanocellulose-graphene composites for on-demand viral deactivation, sulfated nanocellulose mimicking heparin’s virus-trapping properties, and engineered biopolymer hybrids for targeted drug delivery and mucosal immunity. Translational applications span antiviral coatings, self-sterilizing filters, and regenerative More > Graphic Abstract

Abstract Lignocellulosic waste, consisting mainly of cellulose, hemicellulose and lignin, is the most abundant global biomass. Industries generate millions of tonnes of this waste biomass every year. This includes: sugarcane bagasse, corncob, rice straw and husk, oil palm fibres and empty fruit bunches, wheat straw, brewer’s spent grains, among others. These wastes could be valorized to produce high-value industrial lignocellulase enzymes, such as cellulases, hemicellulases and ligninases, by several microorganisms, including bacteria and fungi. Furthermore, the crude or purified lignocellulase enzymes or the microbes producing these enzymes could be used to hydrolyze the lignocellulosic wastes into… More >

Abstract Graphene oxide (GO) has shown great potential in agricultural applications, however, its concentration-dependent effects on cucumber (Cucumis sativus L.) growth, nutrient absorption, and root architecture remain unclear. In the present study, a hydroponic experiment was conducted with different GO concentrations (0.5, 1.0, and 2.0 mg L⁻¹) and setting the non-GO treatment (0.0 mg L⁻¹) as the control for cucumber plants (cv. Qingbaizao). The results showed that low to moderate concentrations (0.5–1.0 mg L⁻¹) significantly promoted cucumber growth, increased shoot and root biomass, enhanced the accumulation of nitrogen, phosphorus, and potassium, and optimized root architecture by increasing cellulose and… More >

Abstract This study characterizes biocomposites derived from jicama starch and reinforced with microfibers obtained from jicama bagasse (JB). The incorporation of jicama bagasse microfibers into the jicama matrix was systematically varied at concentrations of 1, 2, 3, 4, and 5 wt%. The starch film and biocomposite were prepared using solution casting methodologies, employing glycerol as a plasticizing agent. The biocomposites were characterized using Fourier-transform infrared spectroscopy, X-ray diffraction analysis, and scanning electron microscopy. In addition, the moisture absorption and tensile properties were evaluated. The jicama starch contained 44% w/w amylose, whereas the jicama bagasse microfiber contained… More >

Abstract Wound healing is a complex and dynamic process essential for restoring the integrity of damaged skin. It requires wound dressings that actively regulate the wound microenvironment by preventing infection, maintaining moisture balance, allowing gas exchange, and managing exudate. Natural polysaccharides, such as konjac glucomannan (KGM), chitosan, and cellulose, are well suited to this role because of their biocompatibility, biodegradability, and intrinsic bioactivity. Extensive research has focused on developing polysaccharide-based wound dressings with enhanced functionality to promote healing. This review examines recent scientific research published mostly in the past five years on the development and application… More > Graphic Abstract
