Magnesium alloys are used or considered for lightweight structures and biodegradable implants, but high electrochemical activity, limited wear resistance, and localized corrosion still limit their service reliability. Plasma electrolytic oxidation (PEO), also called micro-arc oxidation (MAO), forms an adherent ceramic scaffold. Discharge channels, interconnected pores, thermal …

Orthodontic adhesives can accumulate biofilm, which may lead to long-term white-spot lesions; however, incorporating poly (lactic-co-glycolic acid) (PLGA) nanoparticles could improve their anticariogenic properties. Objective: To develop PLGA nanoparticles containing antiseptic agents for orthodontic adhesives, improve antibacterial activity against Streptococcus mutans, and as…

Natural aggregate concrete is prone to crack propagation and overall crushing under impact load, making it difficult to satisfy the service requirements for collapse resistance in building structures. In order to improve the impact resistance of concrete, this study investigated the impact of the mechanical behavior of steel–polypropylene hybrid fiber-reinforced concrete (SPFRC…

Rosin- and castor-oil-derived resins provide a renewable platform for rapidly curable protective coatings, but the effects of formulation and curing route remain insufficiently resolved. Four composite formulations containing modified rosin glycerol ester (MRGE) and modified castor oil anhydride (MCOA) were cured thermally using ultraviolet irradiation or electron beam (EB) irr…

To address the problem of the short service life of relay injection molds caused by erosion of high-temperature glass fibers, AlCrN coatings were deposited on the surface of ELMAX mold steel using multi-arc ion plating technology. The surface morphology, cross-sectional morphology, and elemental composition of the coatings were analyzed using scanning electron microscopy (SEM) …

To address the environmental hazards caused by massive bauxite red mud stockpiles, phase-change unburned bricks have been developed. The slump flow and initial setting time of fresh mortar were tested, while the flexural strength, compressive strength, splitting tensile strength and rebound hardness of hardened mortar specimens were measured. The synergistic influence of steari…

In this study, a lanthanum-modified MgAl double-layer hydroxide (La-LDH) was synthesized and investigated as a novel inorganic consolidant for gypsum, lime and cement-based mortars. The material was characterized by X-ray diffraction, WDXRF, SEM, dispersion stability analyses and DLS. XRD confirmed the formation of a hydrotalcite-like structure with secondary phases of lanthanu…

Coating degradation and corrosion prediction are moving from empirical regression toward scientific machine learning (SciML), which embeds governing equations, geometry, and uncertainty into data-driven models. This critical review examines physics-informed neural networks (PINNs), neural operators, phase-field hybrids, graph neural networks, and probabilistic models relevant t…

This study investigated the antimicrobial efficacy, biodegradability, and cytotoxicity of carvacrol-infused hemicellulose/methylcellulose (HB/MC)-based coating solutions and films for active food packaging applications. Micro-emulsified (M) and coarse (C) HB/MC solutions with 1 or 2% carvacrol (Car) were investigated. Their antimicrobial properties were evaluated by applying th…

This study explores the performance of an ultrathin Cu2ZnSnSe4 (CZTSe) absorber-based solar cell using numerical simulations carried out with SCAPS-1D software (version 3.8). Ultrathin absorber layers, generally thinner than 500 nm, are attractive because they require less material, reduce manufacturing costs, and can improve carrier collection due to the shorter distance that …

As a paradigm-shifting hypervelocity propulsion technology, electromagnetic rail launch (EMRL) is fundamentally constrained by armature/rail (A/R) interface degradation, which directly erodes its service longevity and operational reliability. Small-caliber circular bore electromagnetic launchers (SCCB-EMRL) offer superior structural integration and ballistic stability over trad…

The weak mechanical behavior of recycled aggregate concrete (RAC) stems from microstructural defects in its composition. This study investigates the reinforcement of RAC through steel fiber incorporation. Using RAC replacement ratios and steel fiber contents as variables, this study examined their effects on compressive strength, splitting tensile strength, elastic modulus, and…

Pitting corrosion is a more insidious and dangerous failure mode than uniform corrosion for protective coatings in marine environments, especially when sulfide ions (S2−) are present. In this work, Inconel 625 (IN625) and IN625-5 wt.% yttria-stabilized zirconia (YSZ) composite coatings were fabricated on 20G steel by laser-directed energy deposition (LDED) using optimized param…

Transparent conductive oxides (TCOs) are indispensable core materials for optoelectronic devices, yet the inherent conflict between electrical conductivity and optical transparency, along with the scarcity and brittleness of indium tin oxide (ITO), severely limits their sustainable development. This review systematically summarizes the research progress of next-generation TCOs,…

In this study, a three-dimensional transient multi-physics coupled numerical model of narrow-gap tungsten inert gas (TIG) welding of TC4 alloy is established, and the heat transfer, flow behavior of the liquid metal in the molten pool, and the formation mechanism of sidewall lack-of-fusion defects are quantitatively investigated. The results show that, along the groove width di…

In this study, 8YSZ thermal barrier coatings (TBCs) were deposited on IC21 single-crystal superalloy substrates. Short-term overheating at 1300 °C was conducted for durations of 1, 5, and 10 min under both uniform temperature and simulated service conditions, followed by thermal cycling and thermal shock tests, respectively, to investigate the short-term overheating behavior of…

This study deals with the influence of the pressure steaming process on color changes and acidity development in the heartwood and sapwood zones of pine wood (Pinus sylvestris L.). The hydrothermal treatment was carried out in a pressure autoclave under two different technological modes: Mode I (105 °C) and Mode II (120 °C) with exposure times of 6 and 18 h. The results showed …
