    Development of Filter Composites Based on Eucalyptus Cellulosic Nanofibers, Sugarcane Bagasse Fibers and Soybean Hulls Applied in Biodiesel Purification

    Flávia Naves Ferreira do Prado1, Michelle Garcia Gomes1, Marcela Piassi Bernardo1, Daniel Pasquini1,*, Anízio Márcio de Faria2, Luís Carlos de Morais3,*

    Journal of Renewable Materials, Vol.13, No.5, pp. 957-980, 2025, DOI:10.32604/jrm.2025.02024-0014 - 20 May 2025

    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

    Oncology Research, Vol.33, No.3, pp. 641-651, 2025, DOI:10.32604/or.2024.050057 - 28 February 2025

    Abstract Background: Cisplatin (DDP) has been used in the treatment of various human cancers. However, DDP alone lacks efficacy in treating triple-negative breast cancer (TNBC), and its clinical application is often hampered by side effects. Astragalus polysaccharide (APS) is one of the active components extracted from Astragalus membranaceus and has gained attention for its various biological properties. This research is aimed to evaluate the effectiveness of a combination of APS and DDP on TNBC and explore the potential mechanisms. Methods: The efficacy and mechanisms of single or combined treatment were evaluated using Cell Counting Kit-8 (CCK8) assay, Annexin… More >

    Journal of Renewable Materials, Vol.13, No.2, pp. 251-272, 2025, DOI:10.32604/jrm.2025.057487 - 20 February 2025

    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. Various applications can benefit from their antibacterial properties,… More > Graphic Abstract

    Influence of Rayleigh-Taylor Instability on Impurity Dynamics during Column Back-Flushing Filtration

    Yanina N. Parshakova*, Andrey Ivantsov

    FDMP-Fluid Dynamics & Materials Processing, Vol.20, No.12, pp. 2709-2720, 2024, DOI:10.32604/fdmp.2024.052396 - 23 December 2024

    Abstract During the manufacturing or processing of materials, large volumes of water of the required quality are often needed. Industrial water treatment and water purification is the process of removing impurities and pollution from the considered medium. To obtain liquid with specified quality parameters, complex systems of filters and treatment facilities are generally used. In this work, the cleaning process for a filtration column is studied. Three-dimensional numerical simulations of flow in a columnar array consisting of a porous medium are conducted. In particular, a model case corresponding to laboratory conditions is examined, with potassium salt… More >

    The Quasi-Static Compressive Properties and Energy Absorption Behavior of Alumina/Aluminum Lattice Structure Composites

    Han Wang1,*

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.31, No.3, pp. 1-1, 2024, DOI:10.32604/icces.2024.012843

    Abstract Aluminum lattice structures have the advantages of lightweight, high specific strength/stiffness and excellent plasticity, while alumina ceramic lattice structures usually show high strength and significant brittleness. Therefore, alumina/aluminum interpenetrating composites can combine two distinct mechanical properties and show superior performance, which is beneficial to applications in aerospace and military industries. In this study, alumina ceramic lattice structures were prepared by additive manufacturing (AM) and used as infiltration skeleton. The molten aluminum was then infiltrated into alumina ceramic lattice structures. By this method, the alumina/aluminum ordered structure composites were prepared. Through mechanical experiments and finite element More >

    A Study of High Volume Fraction SiC/Al Composites Prepared by a Novel Hybrid Additive Manufacturing

    Guizhou Liu1,2, Chunze Yan1,2,*, Yusheng Shi1,2

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.30, No.4, pp. 1-1, 2024, DOI:10.32604/icces.2024.013340

    Abstract High-volume-fraction SiC/Al (HVF-SiC/Al) have a wide range of applications in aerospace, optics, automotive and electronic packaging. However, because the hardness, brittleness and wear resistance increase with the increase in the volume fraction, it is difficult for traditional methods such as machining, to process HVF-SiC/Al composites to complex components. Therefore, in this paper, a novel method of the hybrid additive manufacturing is proposed to fabricate HVF-SiC/Al parts with complex structures. The effect of polymer infiltration and pyrolysis (PIP) on microstructure and properties of HVF-SiC/Al composites is investigated. The results show that the mechanical properties of the… More >

    Abstract Multi-layer membrane filtration is a widely used technology for separating and purifying different components of a liquid mixture. This technique involves passing the liquid mixture through a series of membranes with decreasing pore sizes, which allows for the separation of different components according to their molecular size. This study investigates the filtration process of a fluid through a two-dimensional porous medium designed for seawater desalination. The focus is on understanding the impact of various parameters such as the coefficient of friction, velocity, and the number of layers on filtration efficiency. The results reveal that the More >

    Abstract Objectives: The pro-oncogenic effects of NCAPD2 have been extensively studied across various tumor types; however, its precise role within the context of lung adenocarcinoma (LUAD) remains elusive. This study aims to elucidate the biological functions of NCAPD2 in LUAD and unravel the underlying mechanistic pathways. Methods: Utilizing bioinformatics methodologies, we explored the differential expression of NCAPD2 between normal and tumor samples, along with its correlations with clinical-pathological characteristics, survival prognosis, and immune infiltration. Results: In the TCGA-LUAD dataset, tumor samples demonstrated significantly elevated levels of NCAPD2 expression compared to normal samples (p < 0.001). Clinically, higher… More >

    Numerical Analysis of Permeability of Functionally Graded Scaffolds

    Dmitry Bratsun*, Natalia Elenskaya, Ramil Siraev, Mikhail Tashkinov

    FDMP-Fluid Dynamics & Materials Processing, Vol.20, No.7, pp. 1463-1479, 2024, DOI:10.32604/fdmp.2024.047928 - 23 July 2024

    Abstract In this work, we numerically study the hydrodynamic permeability of new-generation artificial porous materials used as scaffolds for cell growth in a perfusion bioreactor. We consider two popular solid matrix designs based on triply periodic minimal surfaces, the Schwarz P (primitive) and D (diamond) surfaces, which enable the creation of materials with controlled porosity gradients. The latter property is crucial for regulating the shear stress field in the pores of the scaffold, which makes it possible to control the intensity of cell growth. The permeability of functionally graded materials is studied within the framework of… More > Graphic Abstract
