Summary: In order to reduce the occurrence of restenosis and thrombosis in stents, it has been clinically proven that using a thinner-strut stent is effective. Therefore, there is a current trend towards using ultrathin-strut (<= 70 μm) designs for durable stents. However, stents made from biodegradable platforms have not been able to achieve breakthroughs across generations due to their excessively thick struts.

Summary: High-temperature nitriding technology was used to prepare TiN coating on Ni-Ti alloy-based braided stents, improving wear and corrosion resistance. TiN coating exhibited good nano-mechanical, tribological, electrochemical corrosion, nickel ion release, and cytotoxicity properties. The feasibility of using TiN coating as a protective layer on braided peripheral vascular stents was explored through systematic evaluation. This study provides valuable insights for the development of more durable and reliable stents.

Summary: This study investigates the effects of hybrid inorganic short-cut carbon fiber and basalt fiber on the rheological and mechanical performances of shale gas well cement. The results show that the combination of carbon fiber and basalt fiber not only does not affect the workability and pumpability of the cement slurry, but also improves its sedimentation stability, tensile strength, flexural strength, and mitigates the brittleness of the cement stone.

Summary: Wearable services based on flexible and conductive hydrogels have rapidly evolved and found numerous applications. However, creating hydrogels that meet all the requirements can be a lengthy and complicated process. In this study, a double network conductive hydrogel (PHTF@DNH) was quickly generated using a double autocatalytic system. The hydrogel exhibited excellent mechanical and electrical properties, as well as desirable toughness and cyclic compression and swelling properties. The hydrogel-based sensors showed exceptional electrical conductivity, sensitivity, and signal stability, even at low temperatures. It is also harmless to human skin. We believe that PHTF@DNH offers a new approach to the manufacture of sensitive wearable electronic devices.

Summary: Articular cartilage is essential for knee joint motion, acting as a connective tissue to distribute loads and withstand high-stress loadings. However, its self-repair capacity is limited due to the absence of vascular, neural, and lymphatic tissues. Therefore, the development of new approaches and materials for cartilage repair is crucial.

Summary: This paper analyzes the tensile properties of 2D braid reinforced composites in relation to process-induced fiber architecture variations. Parametric study and image analysis are conducted to determine the effects of radial braiding parameters on the braid characteristics and mechanical properties. The results show strong correlations between measured fiber architectures and mechanical properties, suggesting the importance of detailed information about the fiber architecture for predicting the properties of 2D braided composites.

Summary: This study designed and manufactured four types of woven vascular grafts and measured their permeability to water, simulated plasma, and anticoagulated whole blood. Correlations among water permeability, simulated plasma permeability, and anticoagulated whole blood permeability were established. Results showed steady correlations between water permeability and anticoagulated whole blood permeability, suggesting that evaluating blood permeability using water permeability is feasible and objective.
