This research introduces an innovative waterborne intumescent epoxy coating (P-S-IEC) reinforced by in-situ polymerized polyaniline-silicon carbide (PANI-SiC) hybrids, which simultaneously achieves the dual functions of flame retardancy and corrosion protection. The PANI-SiC hybrids are chemically grafted, synergistically combining the thermal insulation properties of SiC nanosheets with the passivation and char-forming abilities of PANI. Large-scale combustion tests show that the P-S-IEC coating maintains its structural integrity even after being exposed to a 1200 °C flame for 120 min, with an impressively low backside temperature of 289 °C. This performance significantly surpasses that of control coatings containing either PANI or SiC alone. Electrochemical analysis further reveals its outstanding corrosion resistance: after immersion in a 3.5 % NaCl solution for 20 days, the charge transfer resistance ( R ct ) remains as high as 7.43 × 10⁷ Ω·cm², and the corrosion current density is only 2.23 × 10⁻⁸ A/cm². The enhanced flame retardancy of the P-S-IEC coating can be attributed to the thermal insulation provided by SiC and the intumescent char expansion of PANI, which together form a stable three-dimensional carbon layer with reduced microporosity. Regarding corrosion protection, the coating benefits from the tortuous path effect of SiC, which hinders ion penetration, and the electrochemical passivation of the steel substrate induced by PANI. This study offers a scalable approach for developing multifunctional coatings that integrate passive shielding and active protection mechanisms. It effectively addresses key challenges in ensuring structural fire safety and long-term corrosion resistance for various industrial applications.

Densification of silicon carbide (SiC) ceramic membrane typically requires sintering temperatures above 2000 °C, resulting in high energy consumption and substantial fabrication costs, and conventional SiC membrane exhibit limited removal efficiency for small molecules. To address these challenges, a co-sintering method was employed to fabricate cobaltic oxide (Co 2 O 3 ) loaded SiC catalytic membrane, with the Co 2 O 3 content systematically optimized. Co 2 O 3 functions as both a sintering temperature-lowering aid and an active site for catalytic ozonation of pollutants. Compared to pure SiC membrane (water permeability: 1200 L m −2 h −1 bar −1 ; flexural strength: 10.5 MPa), the Co@SiC membrane demonstrated significant improvements in both water permeability (1400 L m −2 h −1 bar −1 ) and mechanical strength (13.0 MPa). Numerical simulation further elucidated the neck formation dynamics. Moreover, Co@SiC membrane effectively degrades 95 % Congo red within 20 min, attributed to the generation of superoxide radicals (•O 2 − ). Density functional theory (DFT) calculations illustrated Co sites can effectively absorb ozone molecules and break O-O bond in ozone to generate •O 2 − . Fukui index analysis further indicated •O 2 − tend to attack N=N double bonds in dye molecules. This study proposes a comprehensive understanding of low-temperature sintering behavior and catalytic ozonation performance of Co 2 O 3 modified composite membrane, offering a sustainable strategy for membrane fabrication and wastewater treatment.

The precise tailoring of bandgap structures as well as carrier separation and transport behavior via heterojunction engineering can provide a practical and viable pathway for enhancing the performance of low-dimensional semiconductor devices. In this study, a highly photosensitive photoelectrochemical (PEC) ultraviolet (UV) photodetector (PD) based on a SiC/ZnO heterojunction is explored. The surfaces of SiC nanowires are successfully modified using high-quality ZnO nanospheres via a simple hydrothermal process. The as-constructed SiC/ZnO heterojunction nanowire PEC UV PD achieves high photodetection performance—high responsivity (15.76 mA W −1 ), high detectivity (1.827 × 10 10 Jones), excellent external quantum efficiency (5.21%), and fast rise/decay times (186/454 ms), under 375-nm UV illumination. Remarkably, the device exhibits a high photoresponse under different solution concentrations, temperature conditions, and excellent aging stability over long-term operation. Its highly sensitive and reliable photodetection performance could be attributed primarily to the synergy among the type-II charge transfer pathways formed at the SiC/ZnO heterojunction, enhanced photogenerated-carrier separation efficiency, and improved light–matter interactions enabled by the large specific surface area of the ZnO nanospheres. Overall, this study establishes a paradigm for developing highly sensitive PEC PDs suitable for optical communication under harsh underwater conditions, thereby advancing heterojunction and interfacial engineering strategies for next-generation optoelectronics.

Carbon fiber-reinforced resin matrix composites have been utilized as structural and bearing parts in aerospace because of their high specific strength and modulus. To improve the mechanical properties and wear resistance of carbon fiber-reinforced epoxy resin composites, we propose the in-situ growth of SiC nanowires on the surface of carbon fiber by a Chemical Vapor Deposition method. The effect of the addition of nanowires on the mechanical strength and wear resistance of carbon fiber-reinforced epoxy resin composites was investigated. The results indicated that the tensile strength and bending strength of SiCnws / Cf / epoxy resin composites increased by 13.8% and 16.2% on the condition that the concentration of Ni(NO3)2 catalyst was 0.1 mol/L, respectively. The improvement of the mechanical properties could be attributed to the mechanical interlocking affection between carbon fiber and SiC nanowires. In addition, due to SiC nanowires with a three-dimensional network structure on the surface of carbon fiber, the stronger adhesive force between epoxy matrix SiC nanowires protected the resin matrix and carbon fiber from abrasion. The wear rate of SiCnws / Cf / epoxy composites was reduced by 98.1%.

To address the poor mechanical properties of hexagonal boron nitride (h-BN) ceramics while maintaining their high directional thermal conduction performance, this study proposes a laminated structure design using h-BN as the soft, thermally anisotropic matrix layer and ZrB 2 -SiC as the hard reinforcing layer. h-BN/ZrB 2 -SiC laminated composite ceramics with different layer thickness ratios were fabricated via tape casting and hot-pressing. The h-BN grains maintain strong preferred orientation with their c-axes aligned parallel to the sintering pressure, even after introducing ZrB 2 -SiC layers. At an optimal layer thickness ratio of 1:1, the laminated ceramic achieves the best mechanical performance, with a flexural strength of 169.09 ± 18.67 MPa and a fracture toughness of 8.32 ± 0.97 MPa·m 1/2 , representing increases of 74% and 169%, respectively, compared with tape casted monolithic h-BN ceramics. These enhancements arise from synergistic toughening mechanisms including crack deflection, branching and delamination. Moreover, the laminated structure preserves strong anisotropic thermal conduction. At a layer thickness ratio of 2:1, the composite exhibits the highest thermal conduction anisotropy, with a temperature difference of ∼5 °C between in-plane and through-plane directions at 150 °C. These results demonstrate that the h-BN/ZrB 2 -SiC laminated architecture effectively combines high directional heat transfer with significantly improved mechanical properties, offering a promising solution for advanced thermal management in microelectronics and high-power devices.

The free silicon content in silicon melt infiltrated ceramic matrix composites (CMC) causes the GPa-range residual microstress in silicon and SiC phases and the MPa-range average residual matrix stress in the Si-SiC matrix. These residual stresses are naturally linked to the matrix cracking stress. The complex effect of free silicon on the matrix cracking behavior in SiC fiber reinforced cross-ply laminate CMCs has been investigated by experiment and thermoelastic analysis. The CMC with the lowest silicon exhibits the highest onset cracking stress. A proposed thermoelastic model, which includes silicon crystallization expansion, reveals that the Si-SiC matrix fracture energy in the low-silicon CMC is nearly doubled due to suppressed elastic potential energy associated with the GPa-range microstresses. This improved fracture energy overturns the effect of matrix residual stress and becomes the dominant factor in determining cracking stress. These results offer an energy-based guideline for improving onset cracking stress.

In this work, AlN whisker-reinforced (Zr, Hf)O 2 coating was prepared on SiC coated carbon/carbon composites by sol-gel and plasma spraying methods. Its cyclic ablation resistance was evaluated using an oxyacetylene torch with a heat flux of 2.38 MW/m 2 . After ablation, the coating showed apparently decreased crack sizes and quantity as compared with the one without AlN whisker addition, pointing out its better crack tolerance. Moreover, the coating had a thinner oxidized region based on the linear ablation rate (−0.042 µm/s), greatly lower than that of pure oxide coating (−0.922 µm/s). After detailed observation and characterization, probable protection mechanism was proposed.

For reactive distillation (RD) process limited by the separation efficiency of gas–liquid mass transfer, if the physical size of the alternating operation in reaction and separation can be further reduced, it would greatly promote the efficiency of the RD process. For this purpose, a structured HY@SiC catalytic packing was developed in which the gas–liquid mass transfer separation process and the catalytic reaction occurred simultaneously on its surface. The HY@SiC catalytic packing was used in a pilot-scale column for experimental study on production of cyclohexyl acetate (CA) by RD to verify the performance of the catalytic packing for the first time. Furthermore, a RD model based on the HY@SiC catalytic packing was established based on the reaction kinetics of HY zeolite catalyst obtained in this work. Finally, a novel RD process with double recycle stream for CA production was proposed, which will be optimized design with TAC minimize as the optimization objective based on sequential iterative algorithm.

To ensure the performance of C/C composites, a surface-modified C/C composite was prepared with a C/C composite as the substrate, one-dimensional SiC as the intermediate, and vertically oriented graphene as the modification material without changing the microstructure or composition of the C/C composites. C/C composite surface modifications were prepared in two steps. Its specific surface area is improved from 0.25 m 2 /g to 10.44 m 2 /g, and the electromagnetic interference shielding efficiency is enhanced from 13.08 dB to 23.86 dB. Different from the C/C composites without surface modification, the electromagnetic interference shielding mechanism of surface-modified C/C composites changed from electromagnetic reflection to the interaction of electromagnetic absorption and reflection. The reason is that the increased specific surface area elongates the transmission paths of the electromagnetic waves by multiple reflections, leading to significantly improved electromagnetic interference shielding efficiency.

In this work, TiO 2 nanocones grown on SiC membrane was used as the support of V 2 O 5 -WO 3 species to prepare V 2 O 5 -WO 3 /TiO 2 @SiC (VWTi(C-X)@SiC) catalytic membrane for dust filtration and NH 3 -SCR denitration. On account of the large specific surface area, abundant surface acid sites and prominent redox property, the optimized VWTi(C-550)@SiC catalytic membrane shows >90% NO removal efficiency at the temperature of 280–360 °C, which are much higher than VWTi(P-550)/SiC catalytic membrane (TiO 2 nanoparticles prepared by traditional vacuum coating titanium sol method was used as the support of V 2 O 5 -WO 3 species, NO conversion <80% at whole tested temperature). Additionally, VWTi(C-550)@SiC displays superior stability during the SO 2 + H 2 O resistance and 300 h long-term test at 300 °C, and exhibits an excellent dust filtration performance (2.5 μm SiO 2 particles interception rate exceeded 99.99%) under all test conditions. More importantly, the structure of nanocones decrease the influence of tensile stresses due to the different thermal expansion coefficients of TiO 2 and SiC membranes, which significantly suppress the fall of VWTi catalyst layer from the surface of SiC during pulse-jet cleaning. Among above results, it can be concluded that the optimized VWTi(C-550)@SiC catalytic membrane shows a prosperous application prospect for the simultaneously dust filtration and NH 3 -SCR denitration of medium–high temperature flue gas .

Herein, the SiC-Fe 0 powders were mechanically synthesized and employed for activation of peroxymonosulfate (PMS) to remove florfenicol (FLO). Compared to Fe 0 /PMS system, up to a 3.97-fold increase in degradation rates of 20 mg/L FLO was observed by 25% ( w / w ) SiC-Fe 0 /PMS system in 5 mins, which could be attributed to the increased specific surface area and electron transfer rate of SiC-Fe 0 . Both the radical and non-radical processes were involved in the SiC-Fe 0 /PMS system, in which 1 O 2 and • O 2 − played the dominant role in the FLO degradation and SO 4 •− as well as • OH also participated in the system. ROSs investigation suggested that 1 O 2 , • O 2 − , SO 4 •− were mainly generated from the decomposition of PMS and • OH was mainly derived from the ZVI (or Fe 2+ )-catalyzed activation of O 2 . Meanwhile, H* has a nonnegligible role in PMS activation or the transformation of iron species. Five intermediates of FLO in SiC-Fe 0 /PMS system were identified and a significant removal of the overall toxicity was observed. The degradation pathways of FLO were proposed to be hydrolysis, hydroxylation and dechlorination. Besides, this SiC-Fe 0 /PMS system shows effective removal rate for 2-chlorophenol, acetaminophen, tetrabromobisphenol A and carbamazepine, and the FLO-polluted surface water and artificial wastewater. Overall, this study demonstrated that SiC-Fe 0 was promising in practical application and provided new insights into the generation mechanisms of ROSs in the ZVI/PMS system.

Vat photopolymerization (VPP) technology has shown great application potential in the manufacture of high-precision complex silicon carbide (SiC) based ceramic components. However, in comparison with the conventional fabrication technologies, the SiC ceramics produced by VPP technology have insufficient strengths or relatively larger shrinkage rates to meet the requirements of practical applications. Herein, we develop a novel bimodal SiC material recipe for VPP technology and prepare Si/SiC composites by the consequent liquid silicon infiltration (LSI) method. The addition of fine SiC particles improves the material’s mechanical properties significantly. The final products possess low shrinkage rates (3.52 ± 0.26% in the x-direction, 3.73 ± 0.39% in the y-direction, and 4.69 ± 0.35% in the z-direction) as well as high flexural strength (363.23 ± 14.21 MPa) and low open porosity of 0.097%. The material compositions and fabrication strategies proposed in this work demonstrate an efficient way for the additive manufacturing of high-precision complex Si/SiC ceramic parts (e.g. lightweight space mirrors and structural ceramic parts).
