Abstract This study investigates the valorization of mussel shell waste as a bio-derived filler in poly(L-lactic acid) (PLLA) to promote sustainable materials aligned with circular economy principles. Mussel shells, a seafood industry byproduct rich in biogenic calcium carbonate, were ground into powder and incorporated into PLLA at 10–50 wt%. The resulting composites were thoroughly characterized using scanning electron microscopy and energy dispersive X-ray spectroscopy (SEM-EDX), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), dynamic mechanical thermal analysis (DMTA), and uniaxial tensile testing to assess morphological, chemical, thermal, and mechanical properties.

Abstract During the preparation of carbon fiber reinforced carbon matrix (C/C) composites from resin based precursors, the glassy carbon derived from resin pyrolysis is difficult to graphitize into an ordered structure during carbonization and graphitization, which adversely affects the performance of C/C composites. To enhance the transformation of resin-derived carbon into an ordered structure, we employed a structurally ordered graphene-based material to modify a phenolic resin/carbon fiber precursor and designed two composite modification structures that are straightforward to implement in processing. The internal microstructure of the composites was characterized by XRD and SEM. The results indicate More >

Abstract The structural integrity and longevity of wind turbine blades are critical determinants of the efficiency and reliability of wind energy systems. As the primary components responsible for converting kinetic wind energy into mechanical torque and subsequently electrical power, the aerodynamic, structural, and material characteristics of rotor blades directly influence turbine performance and operational lifespan. This research addresses the limitations of conventional blade designs, often characterized by stress concentration, fatigue damage, and dynamic instability by introducing a novel diamond-lattice internal support structure aimed at improving mechanical strength, fatigue resistance, and dynamic stability. Finite element simulations performed… More >

Abstract Tungsten-copper laminated composites are promising materials for high heat-flux applications, but their performance is often limited by interfacial instability caused by the thermal-mechanical mismatch between tungsten and copper. In this study, W/W-30Cu/CuCrZr three-layer composites are fabricated by high-pressure torsion (HPT) processing. Experimental characterization and molecular dynamics (MD) simulations are used to systematically investigate the influence of HPT process parameters and intermediate-layer composition on the evolution of microstructure and mechanical properties. HPT processing significantly refines the grains of the W-xCu composites and enhances their homogeneity. After applying 15 revolutions of HPT on W-30Cu composites, the crystallite… More >

Abstract The two distinct types of composite materials (5% to 10%) were developed using recycled polyvinyl alcohol fiber (RPA), silicon nitride fiber (SN), and reduced carbon nanoparticles (RCN). Enhanced microstructural properties and mechanical strength were attained through the application of the 3-glycidoxypropyltrimethoxysilane coupling method. The combination of the resin-like properties of RPA-SN fiber resulted in the formation of robust outer strength and a high bonding structure. RPA-RCN composite materials with a weight percentage of 10% exhibited a tensile strength of 42 MPa. In contrast, RPA-SN-RCN composite materials containing 5% to 10% demonstrated enhanced tensile, bending, and… More >

Abstract Oil palm fiber is a natural fiber derived from agricultural biomass and has gained significant attention as an alternative reinforcement material in composite materials due to its abundance, renewability, and environmental benefits. This review explores the various enhancement techniques applied to oil palm fiber to improve its properties for composite material development. Key areas of focus include chemical treatments, physical modifications, and hybridization with other fibers to improve fiber-matrix bonding, mechanical strength, and thermal stability. Integration of nanomaterials and bio-based resins to enhance the performance and sustainability of oil palm fiber composites is also discussed. More > Graphic Abstract

Abstract Inverse design of advanced materials represents a pivotal challenge in materials science. Leveraging the latent space of Variational Autoencoders (VAEs) for material optimization has emerged as a significant advancement in the field of material inverse design. However, VAEs are inherently prone to generating blurred images, posing challenges for precise inverse design and microstructure manufacturing. While increasing the dimensionality of the VAE latent space can mitigate reconstruction blurriness to some extent, it simultaneously imposes a substantial burden on target optimization due to an excessively high search space. To address these limitations, this study adopts a Variational… More >

Abstract Polypropylene (PP) has low inherent susceptibility to common industrial lasers, which poses a significant challenge for laser-based marking. To improve the laser sensitivity of PP, molybdenum disulfide grafted with polystyrene (MoS₂-g-PS) was synthesized via in-situ free radical polymerization and used as a laser-sensitive filler for PP composites prepared by melt blending. The composites were then marked with a 1064 nm semiconductor laser, producing clear and legible patterns. The marked surfaces were characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), colorimetry, Raman spectroscopy, and thermogravimetric analysis (TGA). The results demonstrate that the PP/MoS₂-g-PS composites exhibit significantly More >

Abstract MoS₂ has excellent properties but low conductivity, limiting its use in supercapacitors. Carbon’s high conductivity and stability enhance MoS₂’s electrochemical performance and cycling stability. This study prepared MoS₂/C composites via a one-step hydrothermal method, exploring the effects of solvents and carbon content. Deionized water as a solvent resulted in composites with large specific surface areas and good electrochemical properties. Increasing carbon content improved electrochemical performance, peaking at a glucose content of 0.28 mmol, achieving a specific capacitance of 202.6 F/g. However, excessive carbon content led to decreased performance. More >
