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 This study focuses on optimizing practical synthesis to produce ultrafine CdS nanoparticles. Three separate chemical synthesis processes, namely microwave, wetchemical, and sonication methods, are used to generate CdS nanoparticles. Moringa oleifera leaf extract employed green syntheses of CdS nanoparticles are also performed for additional discussions. The generated CdS nanoparticles were subjected to a comparative assessment to identify the most effective processing method for synthesizing CdS nanoparticles. Even though the processing parameters were altered over their synthesis, the hexagonal structure was retained in the CdS nanoparticles. The observed results of CdS nanoparticles from XRD, SEM/EDX, and More >

Abstract The total replacement of old fossil fuels poses obstacles, making the production of efficient biogasoline vital. Despite its potential as an environmentally friendly fossil fuel substitute, the life cycle assessment (LCA) of palm oil-derived biogasoline remains underexplored. This study investigated the production of biogasoline from crude palm oil (CPO) based biorefinery using catalytic cracking over mesoporous γ-Al₂O₃ catalyst and LCA analysis. High selectivity of converting CPO into biogasoline was achieved by optimizing catalytic cracking parameters, including catalyst dose, temperature, and contact time. γ-Al₂O₃ and CPO were characterized by several methods to study the physical and chemical… More >

Abstract Food breakdown during storage and transit greatly adds to worldwide food waste. Biodegradable edible coatings derived from natural sources provide a sustainable method to extend the shelf life and preserve the freshness of fresh fruit. This study explores the potential of the readily available and nutrient-rich seaweed, Caulerpa lentillifera, as a base material for edible coatings that can enhance the shelf life and maintain the physicochemical properties of fruits and vegetables. Caulerpa lentillifera, a marine macroalga renowned for its unique biochemical composition, presents a promising avenue for developing sustainable bio-coatings to improve the post-harvest quality of fresh… More >

Abstract This review aims to identify the assets and limitations of Dabema (Piptadeniastrum africanum) as a sustainable alternative to traditional timber species for furniture and construction applications. Dabema is characterized by its high density and dimensional stability, meeting ASTM (American Society for Testing and Materials) standards for mechanical strength, which is essential for promoting its use. However, its limited availability in trade and ingrained habits of use are obstacles to its widespread commercialization. In addition, thermal and oleothermal treatments have shown great potential for improving the characteristics of this wood, although they require ongoing optimization and rigorous More > Graphic Abstract

Abstract Bio-based thermoplastic film from flax fiber and fatty acid (FA) was obtained using trifluoroacetic anhydride (TFAA) as an impelling agent. Different quantities of TFAA/FA, size of flax fiber, and fatty acids were applied to investigate chemical structure in relation to the mechanical properties. Decreasing the quantity of TFAA/FA by almost half from 1:4 to 1:2.5 (flax to TFAA/FA) only reduces by 22% the weight percent gain (WPG) and ester content and reducing flax fiber size slightly increases the WPG and ester content. All the treatments showed significant chemical structure modification, observed by FTIR and… More > Graphic Abstract

Abstract This study explored the thermo-chemical properties of industrial hemp hurd with different provenances, maturity stages, and retting protocols. The findings were then compared to hemp hurd used in the fabrication of citric acid-bonded ultra-low-density hemp hurd particleboard. Pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS), Fourier-transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA) were employed to document the variability of the hurd and comprehend the potential impact on biobased composite applications. The choice of cultivar, maturity stage, and processing modality significantly influenced the chemical composition, presence of functional groups, and thermal stability of the hurd. Py-GC/MS revealed substantial variations… More > Graphic Abstract

Abstract The present study focused on extraction of Lonchocarpus cyanescens (L. cyanescens) fiber (LCF) and the physico-chemical properties of the obtained fiber. The fiber was extracted by manual and traditional rating methods, treated with sodium hydroxide, and characterized to determine its performance properties. The chemical composition of cellulose, hemicellulose, and lignin was determined according to the acid detergent, neutral detergent, and Klason methods, respectively. The results show significant quantities of cellulose (33%), hemicellulose (30%), and lignin (24%) in the studied fibers. LCF exhibited a porous multicellular and poly lamellate network structure (FE-SEM) with a crystallinity index of 56.5%. More >

Abstract The chemical composition and thermal properties of natural fibers are the most critical variables that determine the overall properties of the fibers and influence their processing and use in different sustainable applications, such as their conversion into bioenergy and biocomposites. Their thermal and mechanical properties can be estimated by evaluating the content of cellulose, lignin, and other extractives in the fibers. In this research work, the chemical composition and thermal properties of three fibers, namely bagasse, kenaf bast fibers, and cotton stalks, were evaluated to assess their potential utilization in producing biocomposites and bioenergy materials.… More >

Abstract

Goji berry (Lycium barbarum L.) is substantially dependent on nitrogen fertilizer application, which can significantly enhance fruit yield and Goji berry industrial development in Ningxia, China. This study aimed to analyze the functions of differential nitrogen application rates including low (N1), medium (N2), and high (N3) levels in soil microbial community structure (bacterial and fungal) at 2 diverse soil depths (0–20, 20–40 cm) through high-throughput sequencing technology by targeting 16S RNA gene and ITS1 & ITS2 regions. All the observed physicochemical parameters exhibited significant improvement (p < 0.05) with increased levels of nitrogen and the highest
