Abstract Biodegradable packaging has emerged as a viable alternative to non-biodegradable polymers. This study explores different treatments of agar-carboxymethyl cellulose (CMC) nanocomposites developed via the casting method. We investigated the effects of varying glycerol levels (20%–60%) as a plasticizer and nanocellulose levels (0%–30%) as a filler on the properties of agar-CMC nanocomposites. Key properties analyzed included water vapor permeability, solubility in water, moisture absorption, water contact angle, color properties, and mechanical properties. The films exhibited low water vapor permeability, ranging from 2.50 × 10⁻¹¹ g/msPa to 2.23 × 10⁻¹² g/msPa. Water solubility of the films was below… More > Graphic Abstract

Abstract A stepwise pretreatment process for coconut dregs (CD) has been investigated to enhance availability of hemicellulose. Recently, lignocellulose-rich agricultural waste such as CD has garnered substantial attention as a sustainable raw material for producing value-added bio-products. To optimize the process variables within the stepwise pretreatment using Pulsed Electric Field (PEF) and Solid-State Fermentation (SSF), Response Surface Methodology (RSM) based on Central Composite Design (CCD) was employed. PEF, a non-thermal physical treatment, offers advantages such as low energy consumption and reduced processing times, while SSF utilizes Pleurotus ostreatus to promote biodegradation. A statistical model was constructed using… More > Graphic Abstract

Abstract This article aims to model and analyze the heat and fluid flow characteristics of a carboxymethyl cellulose (CMC) nanofluid within a convergent-divergent shaped microchannel (Two-dimensional). The base fluid, water + CMC (0.5%), is mixed with CuO and Al₂O₃ nanoparticles at volume fractions of 0.5% and 1.5%, respectively. The research is conducted through the conjugate usage of experimental and theoretical models to represent more realistic properties of the non-Newtonian nanofluid. Three types of microchannels including straight, divergent, and convergent are considered, all having the same length and identical inlet cross-sectional area. Using ANSYS FLUENT software, Navier-Stokes equations… More > Graphic Abstract

Abstract The work deals with cellulose paper filled with nanocellulose and SrAl₂O₄:Eu,Dy oxide phosphor. It was found that both nanocellulose and oxide improve the tensile strength of the composites obtained. The samples with the oxide demonstrate a long-lasting photoluminescence (PL) under sunlight and ultra-violet (UV) illumination. Room-temperature the PL spectra reveal a wide multicomponent band spreading over all the visible spectral regions. The short-wavelength part of the band is ascribed to the cellulose-related luminescence, while the long-wavelength PL component with maxima near 540 nm corresponds to the luminescence of the SrAl₂O₄:Eu,Dy phosphor. The dependency of the PL… More > Graphic Abstract

Abstract Bionanocomposite film is produced from renewable and biodegradable natural resources. Although elephant foot yam (EFY) starch (Amorphophallus paeoniifolius) is a promising polymer for bionanocomposite film, the native hydrophilic properties influence the overall performance characteristics. Incorporating virgin coconut oil (VCO) and monoglyceride as hydrophobic components can improve mechanical properties and reduce permeability while increasing the hydrophobicity of the composite. Therefore, this study aimed to determine the effect of adding VCO and monoglyceride on EFY starch-nanocrystalline film at 3 and 5 wt% concentrations. Experimental tests were conducted to evaluate the physical and mechanical properties, water vapor transmission rate… More > Graphic Abstract

Abstract Developing favorable bio-based polymers that replace petroleum-based plastics is an essential environmental demand. Lignin is a by-product of the chemical pulping industry. It is a natural UV protection ingredient in broad-spectrum (UVA and UVB) sunscreens. It could be partially and selectively acetylated in a simple, fast, and more reliable process. In this work, a composite film was prepared with UV-resistant properties through a casting method. Bio-based cellulose acetate (CA) was employed as a major matrix while nano-acetylated kraft lignin (AL-NPs) was used as filler during synthesizing UV-shielding films loaded with various amounts (1–5 wt.%) of… More > Graphic Abstract

Abstract Lignocellulosic materials (LCMs), abundant biomass residues, pose significant environmental challenges when improperly disposed of. LCMs, such as sugarcane bagasse, rice straw, saw dust and agricultural residues, are abundant but often burned, contributing to air pollution and greenhouse gas emissions. This review explores the potential of transforming these materials into high-value carbon nanomaterials (CNMs). We explore the potential of transforming these materials into high-value CNMs. By employing techniques like carbonization and activation, LCMs can be converted into various CNMs, including carbon nanotubes (CNTs), graphene (G), graphene oxide (GO), carbon quantum dots (CQDs), nanodiamonds (NDs), fullerenes… More > Graphic Abstract
