This review summarizes recent progress on nanocellulose and its composite materials as emerging biomaterials for orthopedic implant applications. The three main types of - cellulose nanocrystals (CNCs), nanofibrils (CNFs) bacterial (BNC) possess exceptional mechanical properties exceeding traditional like metals, ceramics polymers. Their high strength, stiffness, porosity, surface area, hydrophilicity biocompatibility make well-suited a scaffold material bone regeneration. covers the fabrication nanocellulose-based composites with polymers to further enhance their performance bioactivity. Various methods are utilized develop implants scaffolds controlled architecture optimized ingrowth. In vitro studies demonstrate supports stem cell osteogenic differentiation growth. vivo results in animal models show regeneration critical sized defects, though challenges remain vascularization. While research is required control degradation scale up manufacturing, has strong potential address limitations current next generation biomaterials. provides comprehensive perspective state-of-the-art advanced implants.

Mesoporous Hollow Carbon Sphere-Embedded MXene Architectures Decorated with Ultrafine Rh Nanocrystals toward Methanol Electrooxidation

Inorganic Chemistry, Journal Year: 2024, Volume and Issue: 63(36), P. 16888 - 16896

Published: Aug. 28, 2024

The development of advanced Pt-alternative anode electrocatalysts with high activity and reliable stability is critical to overcoming the technical challenges direct methanol fuel cells. Here, we propose a robust bottom-up strategy for spatial construction mesoporous hollow carbon sphere (HCS)-embedded MXene architectures decorated ultrafine Rh nanocrystals (Rh/HCS-MX) via stereoscopic coassembly reactions. rational intercalation HCS effectively separates nanowalls achieve rapid mass-transfer efficiency, while intimate coupling hybrid carrier enables their electronic structure optimization, thus contributing strong synergistic catalytic effects. Accordingly, resulting Rh/HCS-MX exhibit outstanding electrooxidation properties in terms large electrochemical active surface areas, mass/specific activities, good long-term stability, all which are significantly superior traditional Rh/carbon black, Rh/HCS, Rh/MXene as well commercial Pt/carbon balck Pd/carbon electrocatalysts.
