Abstract Biocomposites are one of the environmentally friendly materials as a substitute for synthetic plastics used for various applications in the automotive, household appliances industry, and interiors. In this study, biocomposites from Polylactic Acid (PLA) and sugarcane bagasse fibers (SBF) were made using the 3D Printing method. The effect of alkalization with NaOH of 0 (untreated), 4%, 6%, and 8% of the fibers were studied. The SBF in PLA was kept at 2% v/v from the total biocomposite. The characterization of all biocomposite tested using tensile, flexural, impact, scanning electron microscope (SEM), thermogravimetric analysis (TGA), and Fourier… More > Graphic Abstract

Abstract This study explores the bioconvective behavior of a Reiner-Rivlin nanofluid, accounting for spatially varying thermal properties. The flow is considered over a porous, stretching surface with mass suction effects incorporated into the transport analysis. The Reiner-Rivlin nanofluid model includes variable thermal conductivity, mass diffusivity, and motile microorganism density to accurately reflect realistic biological conditions. Radiative heat transfer and internal heat generation are considered in the thermal energy equation, while the Cattaneo-Christov theory is employed to model non-Fourier heat and mass fluxes. The governing equations are non-dimensionalized to reduce complexity, and a numerical solution is obtained More >

Abstract Smart materials with self-healing properties are highly desired. This study investigates graphene-incorporated styrene-isoprene-styrene (SIS) nanocomposites for their self-healing property assisted by Infrared (IR) and microwave radiation. The good thermal conductivity and energy-absorbing capacity of graphene offer self-healing capability to SIS/GnP nanocomposites due to their exposure to IR and microwave radiation. The absorbed energy in graphene is transferred to the SIS matrix, facilitating the diffusion, re-entanglement, and restoration of the SIS polymer chains, resulting in multiple times self-healing capabilities using various external stimuli. All SIS/GnP nanocomposite samples exhibit self-healing behavior, and the healing efficiency rises with… More > Graphic Abstract

Abstract The glass composition (70-x)PbO–(30-y)B₂O₃–(x+y)AlF3, where x and y ranges from 0 to 20 mol%, were prepared using the conventional melt-quenching-annealing technique. The structural and thermal properties of the glasses were comprehensively analyzed using techniques like Differential Thermal Analysis (DTA), Dilatometry, Fourier-Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), and Scanning Electron Microscopy (SEM). XRD confirmed the amorphous, non-crystalline structure of the glasses. The glass network was found to be composed of structural units such as PbO₄, BO₄, BO₃ and AlO₆ using FTIR spectroscopy. FTIR analysis revealed significant structural changes, including the transformation of BO₄ to BO₃ units and the increase… More >

Abstract Pure ZnS and Zn_1-xCr_xS nanoparticles were successfully prepared using the coprecipitation method, where x represents the concentration (x = 0.00, 0.10, and 0.05). There are many analytical methods used, such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and Spectroscopy of energy dispersive (EDS). The magnetism structure of the catalysts was investigated using spectrophotometry (VSM), thermogravimetric analysis (TGA), and differential thermal analysis (DTA). X-ray diffraction studies determine the nanocrystal arrangement and size of microcrystals. As seen in SEM analysis, the particles are agglomerated. The coordination of sulfur ions around zinc ions was examined using FTIR analysis.… More >

Abstract The structural parameter, elastic anisotropy, and thermal properties of cubic MgIn₂S₄ under pressures is examined using first principles techniques. The determined lattice constant exhibits a high level of concurrence with the values reported in existing literature. Based on the mechanical characteristics, there is an observed enhancement in both ductility and anisotropy of MgIn₂S₄ under increased pressure. The investigation focuses on the thermal characteristics, encompassing the impact of temperature and pressure on key parameters such as Debye temperature, Grüneisen constant et al. More >

Abstract The present study focuses on sustainable biopolymer composites created from coconut sheath and basalt fibres, which are biodegradable, environmentally benign, and have low carbon footprints. High specific strength, superior mechanical performance, reduced weight, and improved thermal stability are all displayed by these materials. Four hybrid epoxy composites (C1–C4) were produced utilizing five stacking sequences and compression moulding, demonstrating that hybridization considerably enhances mechanical characteristics. The hybrid and pure basalt fibre composites have larger storage moduli than untreated coconut sheath fibre-reinforced epoxy (2.1 GPa). The greatest glass transition temperature (Tg) for C4 has been determined to More > Graphic Abstract

Abstract The use of polypropylene composites in various industrial fields has expanded considerably in recent years. A number of researches have been carried out to characterize the performance of polypropylene and its composites. However, the effects of ageing on the long-term behaviour of this thermoplastic are not well understood. The purpose of this study is to analyse the consequences of thermal degradation on the thermal and mechanical properties of three distinct materials: virgin Polypropylene (PP), virgin Polypropylene + talc (PP/talc), and virgin Polypropylene + Carbon Black (PP/CB) micro-composites. Specimens of these materials underwent exposure in an… More >

Abstract There are several advantages to the MIG (Metal Inert Gas) process, which explains its increased use in various welding sectors, such as automotive, marine, and construction. A variant of the MIG process, where the same equipment is employed except for the deposition of a thin layer of flux before the welding operation, is the AMIG (Activated Metal Inert Gas) technique. This study focuses on investigating the impact of physical properties of individual metallic oxide fluxes for 304L stainless steel welding joint morphology and to what extent it can help determine a relationship among weld depth… More >

Abstract Lignin, lignosulfonate, and synthesized phosphorylated lignosulfonate were introduced as green fillers in citric acid-sucrose adhesives for bonding particleboard fabricated from areca leaf sheath (ALS). The characteristics of particleboards were compared to that of ultralow emitting formaldehyde (ULEF-UF). The fillers derived from Eucalyptus spp. kraft-lignin were added for flame retardancy enhancement. 10% of each lignin and modified lignin was added into the ULEF-UF and citric acid-sucrose bonded particleboards. Analyses applied to particleboards included thermal characteristics, X-ray diffraction analysis (XRD), morphological properties, Fourier transform infrared spectroscopy (FTIR), as well as physical, mechanical, and fire resistance characteristics of the… More > Graphic Abstract
