Summary: This study presents a novel fabrication strategy using silk fibroin to develop hierarchical microchannel scaffolds for biomimetic nerve microenvironments. The scaffolds successfully induced cell infiltration and migration, and effectively stimulated neural stem cells to differentiate into neurons. When implanted in vivo, the scaffolds induced a mild inflammatory response, recruited cells extensively, and showed potential for nerve injury repair and regenerative medicine.

Summary: A simple, efficient and controllable one-step template method for fabricating poly(epsilon-caprolactone) substrates with micro/nanohierarchical patterned structures is proposed. The influence of geometric patterns, island size, island spacing, and patterned nanowires (pNW) on the growth behavior of MG-63 cells is studied. The results show that MG-63 cells prefer to adhere and grow on substrates with smaller island size or spacing. The strip structure can guide cellular alignment on its surface. Microisland structures and pNW play different roles in promoting cell proliferation, distribution, and morphogenesis. Precisely adjusting the micro/nanostructure of the substrate surface allows for well-controlled growth behavior of MG-63 cells.

Summary: This study has demonstrated the deposition of 3D columnar micro-films/coatings on pre-patterned surfaces with sub-micrometer periodic patterns. Four-angle polarisation analysis was conducted on thin Si and SiO2 films deposited via glancing angle deposition (GLAD) using synchrotron infrared microspectroscopy. The research confirmed the angular dependence of absorbance and proposed the use of patterned SiO2 substrate coated by columnar SiO2 for retardance control in UV-visible applications.

Summary: This paper studies the spectral characteristics of biomimetic micro-nano structures in microwave-transmitting thermal control materials, and finds that the tip height and the air gap have a regulatory effect on the spectral characteristics. The biomimetic structures can decrease the solar absorptance and increase the infrared emissivity, which may give suggestions on adjusting the spectral characteristics of aerospace microwave-transmitting thermal control materials.

Summary: The study aimed to investigate the effective cellular interactions and stimulatory effect of surface topology on the differentiation of osteoblast-like cells using in-vitro cell culture. The results showed that MG63 osteoblast-like cells cultured on the MNS and NS substrates had significantly higher expression levels of osteogenesis-related genes, and higher levels of F-actin. These findings suggest that electrochemical anodization after acid etch and powder blasting treatments is a possible process for high-grade osseointegration in-vivo.

Summary: This article investigates the role of Orc6, a component of the origin recognition complex (ORC), in DNA replication. The study discovers that Orc6 localizes at the replication fork and acts as an accessory factor of the mismatch repair (MMR) complex. In response to oxidative damage during the S phase, Orc6 promotes MMR complex assembly and activity, enabling efficient MMR. This suggests that hOrc6 plays a fundamental role in genome surveillance during DNA replication.

Summary: This study presents an innovative approach to improve the photovoltaic conversion characteristics and stability of perovskite solar cells through carbon electrode interface modification. By in-situ polymerization and carbonization on the surface of nano-graphite, a dendritic structure carbon electrode is formed, reducing the work function and aligning the energy levels with perovskite. This leads to improved charge and hole collection efficiency, resulting in increased photovoltaic conversion efficiency. Furthermore, the modified carbon electrode-based perovskite solar cells exhibit exceptional stability, maintaining high efficiency even without encapsulation.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
