    Shervin Fateh Khanshir1, Saeed Dinarvand2,*, Ramtin Fateh Khanshir3

    Frontiers in Heat and Mass Transfer, Vol.23, No.2, pp. 663-684, 2025, DOI:10.32604/fhmt.2025.060559 - 25 April 2025

    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

    Vitalii Chornii1,2,*, Serhii G. Nedilko1, Maxim Lazarenko1, Oleksandr Alekseev1, Mariia Sosnovs’ka1, Valerii Barbash3, Olga Yashchenko3, Syed Shabhi Haider4, Yaroslav Zhydachevskyy4, Andrzej Suchocki4

    Journal of Renewable Materials, Vol.13, No.4, pp. 653-668, 2025, DOI:10.32604/jrm.2025.058211 - 21 April 2025

    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

    Elephant Foot Yam Starch-NCC Bionanocomposite Film Incorporated with Virgin Coconut Oil and Monoglyceride for Hydrophobic and Biodegradable Packaging

    Heni Radiani Arifin1,*, Yoan Christina Angelica1, Bambang Nurhadi1, Herlina Marta1, Rossy Choerun Nissa2

    Journal of Renewable Materials, Vol.13, No.3, pp. 617-635, 2025, DOI:10.32604/jrm.2025.057812 - 20 March 2025

    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 The increasing severity of air pollution necessitates more effective and sustained air filtration technology. Concurrently, the desire for more environmentally friendly, sustainable materials with better filtering performance and less environmental impact drives the move away from conventional synthetic membranes. This review presents lignocellulosic biocomposite (LigBioComp) membranes as an alternative to traditional synthetic membranes. It focuses on their materials, fabrication, and functionalization techniques while exploring challenges and proposing methods for resourceful utilization. Renowned for their abundance and renewable nature, lignocellulosic materials consist of cellulose, hemicellulose, and lignin.

    Microwave-Assisted Acetylated Lignin Loaded into Cellulose Acetate for Efficient UV-Shielding Films

    Ahmed M. Khalil1, Samir Kamel2,*

    Journal of Renewable Materials, Vol.13, No.2, pp. 401-412, 2025, DOI:10.32604/jrm.2024.057419 - 20 February 2025

    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

    A Greener Future: Carbon Nanomaterials from Lignocellulose

    Hebat-Allah S. Tohamy*, Mohamed El-Sakhawy, Samir Kamel

    Journal of Renewable Materials, Vol.13, No.1, pp. 21-47, 2025, DOI:10.32604/jrm.2024.058603 - 20 January 2025

    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

    Dan Wang, Jihuan Song, Qiyuan Wang, Chenmeng Cui, Ying Yang*

    Journal of Renewable Materials, Vol.13, No.1, pp. 49-78, 2025, DOI:10.32604/jrm.2024.056644 - 20 January 2025

    Abstract Upgrading of abundant cellulosic biomass to isosorbide can reduce the dependence on limited fossil resources and provide a sustainable way to produce isosorbide, utilized for polymers, medicine and health care product synthesis. This review comprehensively examines the key steps and catalytic systems involved in the conversion of cellulose to isosorbide. Initially, the reaction pathway from cellulose to isosorbide is elucidated, emphasizing three critical steps: cellulose hydrolysis, glucose hydrogenation, and the two-step dehydration of sorbitol to produce isosorbide. Additionally, the activation energy and acidic sites during cellulose hydrolysis, the impact of metal particle size and catalyst More > Graphic Abstract

    A Review of Piezoelectric Phenomena as a Key Characteristic of Wood

    Zeynep Eda Özan1,*, Gökhan Gündüz2, Deniz Aydemir1,*

    Journal of Renewable Materials, Vol.12, No.12, pp. 1985-2016, 2024, DOI:10.32604/jrm.2024.056000 - 20 December 2024

    Abstract Piezoelectric materials convert mechanical energy into electrical energy, acting as renewable energy sources. As smart materials, they respond to environmental changes by altering their properties. When pressure is applied, their structure separates positive and negative charge centers, producing opposite charges on crystal surfaces. This generates an electric field and a measurable potential. Wood, a natural material, also exhibits piezoelectric behavior. The piezoelectric effect of wood was first discovered by Russian scientists in 1940–1950. Then, in 1955, Fukada analyzed both the direct and inverse piezoelectric effect of wood and scientifically proved that this natural material has… More > Graphic Abstract
