Summary: In this study, ordered diamond nanopillar arrays were synthesized through a bottom-up approach using porous anodic aluminium oxide (AAO) templates. Commercial ultrathin AAO membranes were used as the growth template, and a three-step fabrication process involving chemical vapor deposition (CVD) was employed. After removing the AAO template, ordered arrays of submicron and nanoscale diamond pillars with diameters of around 325 nm and 85 nm, respectively, were successfully released.

Summary: The eutectic structure in metals and ceramics is a self-organization phenomenon where multiple solid phases solidify in an ordered structure from a liquid phase. Ordered structures of Y3Al5O12 (YAG)-Al2O3 composites were prepared via chemical vapor deposition in the YAG-Al2O3 eutectic system. This study reveals that ordered structures can be formed not only during the melt-solidification process but also during the vapor deposition process.

Summary: Thin double-layer coatings consisting of alumina top coat and mullite bond coat were deposited on SiC substrates using laser chemical vapor deposition (CVD). The effect of the mullite bond coat and the phases of alumina top coat on the structural integrity against thermal residual stress was examined. The double-layer coatings displayed greater tolerance to surface cracks and interfacial delamination compared to single-layer coatings without mullite layers, as simulated and experimentally verified.

Summary: Artificial dura mater plays a crucial role in brain and spinal cord protection and support, but surgical tears are often unavoidable. This study has developed a multifunctional polyurethane (LSPU-2) with biocompatibility, anti-leakage, and self-healing properties, which matches the mechanical properties of the dura mater. It exhibits extremely low cytotoxicity and does not cause any negative skin lesions, and its anti-leakage properties have been confirmed. LSPU-2 can completely self-heal within 115 minutes at human body temperature, making it one of the most promising potential artificial dura materials.
