Abstract With the global diabetes epidemic, diabetic foot ulcers (DFUs) have become a major health burden, affecting approximately 18 million people worldwide each year, and account for about 80% of diabetes-related amputations. Five-year mortality among DFU patients approaches 30%, which is comparable to that of many malignancies. Yet despite standard wound care, only about 30%–40% of chronic DFUs achieve complete healing within 12 weeks. This persistent failure shows that conventional dressings remain passive supports. They do not counteract underlying pathologies such as ischemia, prolonged inflammation, and infection. Recent advances in polymeric nanofiber scaffolds, particularly electrospun matrices,… More > Graphic Abstract

Abstract The combination of two-step synthesis processes is employed for the fabrication of (NiO)(_0.5)/(Fe₂O₃)(_0.5)@C@MoS₂ (NFCM) nanofibers composite through electrospinning and hydrothermal techniques. This nanofiber composite is designed for tunable dielectric materials and electromagnetic interference (EMI) shielding applications. Using impedance spectroscopy, the electrical properties of an NFCM pellet are analyzed using an equivalent circuit model (R₁1<), with a primary focus on the variation of relaxation time with frequency at different temperatures. Utilizing the Mott. variable range hopping (MVRH) model, and small polaronic hopping model, the localization length of the hoping carriers is determined to be 0.98 Å and More >

Abstract Growing environmental concerns and the need for sustainable alternatives to synthetic materials have led to increased interest in bio-based composites. This study investigates the development and characterization of sustainable egg packaging waste (EPW) biocomposites derived from recycled wood fibers and fungal mycelium filaments as a natural binder. Three formulations were prepared using EPW as the primary substrate, with and without the addition of hemp shives and sawdust as co-substrates. The composites were evaluated for granulometry, density, mechanical strength, hygroscopic behavior, thermal conductivity, and fire performance using cone calorimetry. Biocomposites, composed exclusively of egg packaging waste,… More >

Abstract The growing environmental awareness, the search for alternatives to fossil resources, and the goal of achieving a circular economy have all contributed to the increasing valorization of biowaste to produce bio-based polymers and other high-value products. Among the various biowaste materials, lignin has gained significant attention due to its high aromatic carbon content, low cost, and abundance. Lignin is predominantly sourced as a byproduct from the paper industry, available in large quantities from hardwood and softwood, with variations in chemical structure and susceptibility to hydrolysis. This study focuses on softwood lignin obtained through the LignoForce™… More > Graphic Abstract

Abstract Natural fibers, as a typical renewable and biodegradable material, have shown great potential for many applications (e.g., catalysis, hydrogel, biomedicine) in recent years. Recently, the growing importance of natural fibers in these photo-driven applications is reflected by the increasing number of publications. The utilization of renewable materials in photo-driven applications not only contributes to mitigating the energy crisis but also facilitates the transition of society toward a low-carbon economy, thus enabling harmonious coexistence between humans and the environment within the context of sustainable development. This paper provides an overview of the recent advances of natural… More > Graphic Abstract

Abstract Sugarcane bagasse (SCB) is a promising natural fiber for bio-based composites, but its high moisture absorption and poor interfacial adhesion with polymer matrices limit mechanical performance. While chemical treatments have been extensively explored, limited research has addressed how thermal treatment alone alters the surface properties and reinforcing behavior of SCB fibers. This study aims to fill that gap by investigating the effects of heat treatment on SCB fiber structure and its performance in starch/poly (vinyl alcohol) (PVA) composites. Characterization techniques including Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and scanning… More >

Abstract Long-time fermentation has always been one of the reasons restricting the development of straw biological pulping. This study aimed to develop a novel straw pulp film with shortened solid-state fermentation time with less than 20% mass loss rate by bio-pulping synergistic treatment of straw fibers with deep eutectic solvent (DES) and Streptomyces rochei (S. rochei). Results illustrated that at 3% S. rochei concentration with 7-day fermentation, both cellulose and hemicellulose enzyme activities of the treated rice straw fiber reached peak values with a fiber mass loss rate of 17.01%. Microstructural morphology revealed that S. rochei colonization initiated on straw… More > Graphic Abstract

Abstract With the growing demand for sustainable development in the mining industry, cemented paste backfill (CPB) materials, primarily composed of tailings, play a crucial role in mine backfilling and underground support systems. To enhance the mechanical properties of CPB materials, fiber reinforcement technology has gradually gained attention, though challenges remain in predicting its performance. This study develops a hybrid model based on the adaptive equilibrium optimizer (adap-EO)-enhanced XGBoost method for accurately predicting the uniaxial compressive strength of fiber-reinforced CPB. Through systematic comparison with various other machine learning methods, results demonstrate that the proposed hybrid model exhibits… More >

Abstract The use of agricultural residues in biocomposite production has gained increasing attention, driven by several benefits. Converting agricultural by-products into bio-based materials within a circular economy represents a sustainable strategy to mitigate lignocellulosic waste, reduce reliance on fossil resources, and lower environmental pollution. This approach also creates economic opportunities for rural African communities by generating diverse income sources for workers in collection, processing, and manufacturing. As a result, the integration of agricultural residues into biocomposites production not only addresses environmental concerns but also fosters economic growth and supports rural development. In this review, five biomasses… More > Graphic Abstract
