Abstract Phenolic resins are widely used in thermal protection, yet achieving simultaneous improvement in thermal stability and mechanical strength remains challenging. In this work, a vinyl-modified silicone resin (VMTQ) was synthesized and incorporated into a boron phenolic resin (BPF) matrix. Three composite ceramic fillers, Al₂O₃–SiO₂–ZrO₂ (ASZ), Al₂O₃–SiO₂–TiO₂ (AST), and Al₂O₃–SiO₂–MgO (ASM), were further introduced to construct a multi-oxide synergistic reinforcement system. Thermogravimetric analysis shows that the maximum decomposition rate decreases by 0.2–0.3%·min⁻¹, while the ASM/V3/BPF-3 composite exhibits a 74.53% increase in char yield at 800°C and a 163.3°C increase in initial decomposition temperature, confirming its significantly enhanced thermal More >

Abstract This study presents a numerical investigation of the transient relaxation dynamics of a near-critical CO₂ droplet immersed in a warmer supercritical environment composed of the same fluid. Three thermodynamic regimes were analysed: quasi-critical (Tr=1.01,Pr=1.01), transitional (Tr=2.01,Pr=1.01), and deep supercritical (Tr=5.01,Pr=3.01). The evolution of density, temperature, and velocity fields was examined to characterize the internal structure and stability of the interfacial transition layer. The evolution of density, temperature, and velocity fields highlights the competition between thermal diffusion, compressibility, and mass confinement in shaping the stability of the interfacial transition layer. Near the critical point, strong More >

Abstract Spikelet filling characteristics in early-season rice in southern China may be distinctive due to its exposure to high temperatures during the ripening period. However, limited information is currently available on these characteristics. This study aimed to characterize spikelet filling in early-season rice and identify the key factors contributing to its improvement. Field experiments were conducted over two years (2021 and 2022) to mainly investigate the proportions of fully-filled, partially-filled, and empty spikelets, along with the biomass-fertilized spikelet ratio and harvest index, in 11 early-season rice varieties. The results revealed significant varietal variation in spikelet filling,… More >

Abstract This study investigates the thermo–mechanical behavior of C40 concrete and reinforced concrete subjected to elevated temperatures up to 700°C by integrating experimental testing and advanced numerical modeling. A temperature-indexed Concrete Damage Plasticity (CDP) framework incorporating bond–slip effects was developed in Abaqus to capture both global stress–strain responses and localized damage evolution. Uniaxial compression tests on thermally exposed cylinders provided residual strength data and failure observations for model calibration and validation. Results demonstrated a distinct two-stage degradation regime: moderate stiffness and strength reduction up to ~400°C, followed by sharp deterioration beyond 500°C–600°C, with residual capacity at… More >

Abstract Considering the high-temperature application environment and quasi-brittle characteristics, the high-temperature fracture toughness of C/SiC composites is of great significance for the safety application of components in service.
In this work, the fracture toughness of PIP-C/SiC composites at 25–1600 ℃ in inert atmosphere was tested. The test results show that the fracture toughness and modes of C/SiC composites have significant temperature dependence and difference in in-plane and out-of-plane orientations. With the rising of temperature, the carrying capacity and KIC of C/SiC composites increase first and then decrease, and an inflection point occurs near the fabrication temperature.… More >

Abstract In deep underground engineering, geological disposal of nuclear waste, and geothermal development, the granite–mortar interface represents a critical weak zone that strongly influences sealing performance under high-temperature conditions. While previous studies have primarily focused on single materials, the dynamic evolution of interface permeability under thermal loading remains insufficiently understood. In this study, time-resolved gas permeability measurements under thermal cycling (20°C → 150°C → 20°C) were conducted, complemented by multi-scale microstructural characterization, to investigate the nonlinear evolution of permeability. Experimental results indicate that interface permeability at room temperature is approximately one order of magnitude higher than… More >

Abstract Summer high temperatures have severely impaired the growth of herbaceous peony (Paeonia lactiflora Pall.) in East China. While compound fertilizer application enhances soil fertility and promotes plant growth, its efficacy in maintaining optimal plant performance under summer heat stress remains poorly understood. This study investigated the effects of compound fertilizer application on herbaceous peony growth during summer thermal stress. Results demonstrated that compound fertilizer supplementation significantly improved plant growth under elevated temperatures, manifesting enhanced phenotypic characteristics, elevated antioxidant enzyme activities, and increased nutrient accumulation. Compared to untreated controls, fertilized plants exhibited three key responses: (1) increased More >

Abstract V-doped CdTe polycrystalline films can achieve both doping activation and defect passivation by high-temperature CdCl₂ heat treatment, but this requires simultaneous modulation of the amount of CdCl₂ introduced to obtain high-quality films. It is found that increasing the CdCl₂ introduction does not change the physical phase structure and lattice constant of CdTe:As thin films, but promotes grain recrystallisation, and can promote the formation of A-center, and inhibit the formation of Cd vacancy (VCd) defects, as well as the formation of deep energy level defects. The results provide guidance for the improvement of high-temperature CdCl₂ heat treatment of More >

Abstract Hot corrosion behavior of GH4169 nickel-based superalloy coated with 95wt.%Na₂SO₄+5wt.%NaCl salt mixture at 650 ℃,800 ℃, and 950 ℃ were investigated by some material characterization methods. The Experimental results showed that hot corrosion kinetics followed a parabolic, linear and exponential laws at 650 ℃, 800 ℃, and 950 ℃ respectively. Notably, as the temperature ascended from 650 ℃ to over 800 ℃, the corrosion mechanisms underwent a transition from pit corrosion to uniform erosion, corresponding to low-temperature hot corrosion (LTHC) and high-temperature hot corrosion (HTHC). At 650 ℃, a large number of semi-ellipsoidal corrosion pits manifested More >

Abstract This study explores the mechanism behind the generation of pressure pulses on the outer surface of a molten metal droplet when immersed in water. The absence of any external trigger is assumed, and the droplet is surrounded by a vapor layer with surface hydrodynamic waves at the vapor-liquid interface. The study examines the heating conditions of a cylindrical column of water used to model a volume of cold liquid interacting with a hot metal surface, which explosively boils upon direct contact. Within the framework of classical homogeneous nucleation theory, the relationship between pressure pulse magnitude… More >
