Summary: Chemical vapor infiltration (CVI) at low temperature was used to synthesize the BN interface of SiCf/SiC composites. The structure of the BN interface was adjusted by changing the deposition pressure. The study showed that increasing the deposition pressure enhanced the bonding strength but decreased the fracture toughness of the BN interface.

Summary: This study evaluated the mechanical properties of 2D woven SiCf/SiC composites fabricated via precursor infiltration and pyrolysis (PIP) through a three-point bending test. The failure processes of the composites under different loading directions were monitored using an acoustic emission (AE) system and digital image correlation (DIC) technique. The results showed that the damage process was dominated by compressive stress in composites loaded parallel to the layup direction, while tensile stress primarily affected composites loaded perpendicular to the layup direction. The complementary results obtained from the AE system and DIC technique demonstrate the effectiveness of multiple analytical methods in assessing the mechanical behavior of SiCf/SiC composites.

Summary: The boron nitride (BN) interface of SiC fiber-reinforced SiC matrix (SiCf/SiC) composites was fabricated using chemical vapor infiltration (CVI) with BCl3 and NH3 as precursor. The microstructure and chemical composition of the BN interface were studied. The influence of coating thickness on the tensile behavior of SiCf/SiC composites was evaluated. The BN interface synthesized at 800 degrees C displayed a low degree of crystallization and a quasi-isotropic microstructure. The optimal thickness of the BN interface was found to be about 670 nm.

Summary: SiC fiber/SiC composites modified by in-situ grown SiC nanowires to form a hierarchical structure showed improved matrix infiltration efficiency, enhanced bending test performance, and increased strength with BN-coated SiC nanowires. The nanowires delayed early damage evolution and contributed to hindering and bridging of microcracks, further enhanced by the BN coating.

Summary: This paper investigates the effect of pyrolytic carbon (PyC) interphase on the interface shear behavior of SiCf/SiC composites through molecular dynamics simulations. The results show that the deformation behavior of the interface changes from localized penetrating sliding to large-scale uniform plasticity as the orientation angle (OA) increases. The mechanism of weakening shear resistance through the introduction of amorphous carbon (a-C) component is revealed. Moreover, the strain rate effect on the interfacial shear strength is discussed.

Summary: The tensile test of 2D SiC(f)/BN(i)/(SiC-B4C)((m)) was conducted with acoustic emission (AE) online monitoring to study mechanical properties and failure mechanisms. Pattern recognition technique was used to determine the relationship between AE signals and damage mechanisms, leading to the proposal of an improved sentry function. The loading process was found to consist of four stages with different damage mechanisms dominating each stage.

Summary: In this study, SiC nanowires (SiCNWS) were grown on the surface of PyC interface via chemical vapor infiltration (CVI) to enhance the mechanical characteristics and thermal conductivity of three-dimensional SiCf/SiC composites. The presence of SiCNWS resulted in a 46% increase in flexural strength and significant enhancement of thermal conductivity in the temperature range of 25-1000 degrees C. Analysis of energy release during damage evolution process revealed delayed damage evolution due to decreased porosity, crack deflection, and bridging of SiCNWS. The excellent thermal conductivity was attributed to thermally conductive pathways formed by SiCNWS in the dense structure.

Summary: Introduction of Y2O3 into the SiC matrix improves the wet-oxidation resistance of SiCf/SiC composites. The effects of Y2O3 on the mechanical properties and wet-oxidation resistance were investigated. The results show that Y2O3 has little negative effect on the mechanical properties and effectively improves the wet-oxidation resistance by forming a continuous Y2Si2O7 layer during oxidation. The strength retention rates of SiCf/SiC-Y2O3 composites increase by 5.62%, 17.58% and 23.08% after oxidation at 1400 degrees Celsius for 20 h, 60 h and 100 h respectively.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
