Abstract In this study, the casting process is used to fabricate modified polyvinyl alcohol (PVA), starch (S), and carboxymethyl cellulose (CMC) polymer blend films (PVA/S/CMC) loaded with various concentrations of iron-doped carbon quantum dots (Fe-CQDs) and denoted as (PVA/S/CMC@Fe-CQDs). A one-step microwave strategy was employed as a facile method to prepare Fe-CQDs. Through a series of characterization techniques, fourier-transform infrared (FTIR) spectroscopy, x-ray diffraction (XRD) analysis, and scanning electron microscopy (SEM) have been used to show the successful integration of Fe-CQDs into the PVA/S/CMC matrix. Loading the synthesized Fe-CQDs to the polymeric matrix significantly enhanced the… More > Graphic Abstract

Abstract This research aims to investigate the potential of a plant cellulose developed from Opuntia ficus-indica (OFI) cladode as a sustainable and renewable adsorbent for the removal of neutral red (NR), a cationic dye pollutant, from aqueous environments. Analysis of raw and treated OFI using X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier Transform Infrared Spectroscopy (FTIR) demonstrated the successful extraction of type cellulose. The Brunauer–Emmett–Teller (BET) analysis of the nitrogen adsorption-desorption isotherm revealed an improved specific surface area of 12.4 m²/g after treatment. A systematic study of key parameters in batch adsorption experiments revealed removal rates… More > Graphic Abstract

Abstract In the past two decades, nanocellulose has become an innovative material with unique properties. This substance has exceptional mechanical strength, an extensive surface area, and biodegradability. Collaborative integration of nanocellulose offers a more environmentally friendly solution to the current limitations by substituting carbon. Due to its versatility, nanocellulose is commonly employed in various industrial sectors, including paints, adhesives, paper production, and biodegradable polymers. Such versatility enables the creation of customized structures for potential use in emulsion and dispersion applications. Given its biocompatibility and nontoxicity, nanocellulose is particularly well-suited for biomedical purposes such as tissue engineering, 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 Food packaging is becoming popular as the consumption of ready-to-eat food products rises. Easy-to-use, non-biodegradable plastic packaging is commonly used in food packaging, contributing to the deteriorating environmental situation. This issue increases the concern for the environment and encourages the usage of alternative materials. Cellulose nanofibrils (CNF) are abundant and biodegradable, which makes them ideal candidates to replace plastic coatings. The ability to form H-bonds between the hydroxyl groups makes coated paper with CNF have good strength, but poor barrier properties. The barrier properties can be improved by grafting DMAEMA or HEMA onto CNF (CNF-g-PDMAEMA… More > Graphic Abstract

Abstract Petrochemical plastics are widely used for food protection and preservation; however, they exhibit poor biodegradability, resisting natural degradation through physical, chemical, or enzymatic processes. As a sustainable alternative to conventional plastic packaging, edible films offer effective barriers against moisture, gases, and microbial contamination while being biodegradable, biocompatible, and environmentally friendly. In this study, novel active food packaging materials (in film form) were developed by incorporating starch, carrageenan, nanocellulose (NC), Aloe vera, and hibiscus flower extract. The effects of varying the matrix composition (26.5–73.5 wt.% starch/carrageenan), NC concentration (2.77–17.07 wt.%), and particle type (fibers or crystals) on… More > Graphic Abstract

Abstract In this research, the antibacterial properties of a composite material prepared from agave bagasse cellulose fibers doped with silver nanoparticles and chitosan were studied. The development of composite materials with antibacterial properties and environmentally friendly based on cellulose fibers from agave bagasse with silver nanoparticles prepared by green synthesis and chitosan from shrimp waste enhances the value of these agro-industrial wastes and offers the opportunity for them to have biomedical applications since these raw materials have been poorly reported for this application. The antibacterial properties of chitosan and silver nanoparticles are already known. However, the… More > Graphic Abstract

Abstract This study prepared and characterized amphiphilic carboxymethyl cellulose stearate (CMCS) recycled from sugarcane bagasse agro-waste (SB). The Fourier-transform infrared (FTIR) analysis confirmed cellulose, carboxymethyl cellulose (CMC), and CMCS structures, with CMCS showing increased H-bonding. X-ray diffraction analysis (XRD) revealed reduced crystallinity in CMC and CMCS. CMCS exhibited a hydrophobic nature but dispersed in water, enabling nanoemulsion formation. Optimal nanoemulsion was achieved with CMCS1, showing a particle size of 99 nm. Transmission electron microscopy (TEM) images revealed CMC’s honeycomb structure, transforming into spherical particles in CMCS1. Antimicrobial tests demonstrated strong activity of CMCS formulations against Escherichia coli More >

Abstract Alternative methods for biodiesel purification that focus on ease of operation, cost reduction, and elimination of contaminated residues or that are easier to treat have received more attention. The dry wash route was used as an alternative to the wet route in biodiesel production. Filter membranes were developed based on cellulose nanofibers as the matrix and sugarcane bagasse fibers or soy hulls, as reinforcement to the matrix, before and after two chemical treatments (carboxymethylation and regeneration with sulfuric acid). The filters were characterized by permeability capacity, morphology, wettability, porosity, SEM and mechanical properties. The filtered… More > Graphic Abstract
