Scientists fabricate composites that combine high strength and bioactivity inspired by the cortical bone Researchers have created scaffolds with enhanced strength by fabricating 20 vol% polydopamine-modified nano hydroxyapatite (pDA-nHA), featuring a distinctive lamellar structure. These scaffolds were then immersed in a polyetherketoneketone (PEKK) synthesis system for reinforcement, offering an innovative approach to both augment the mechanical robustness of the material and enhance the bioactivity of PEKK.

Alkali-decorated microenvironments aid Cu single atom catalysts in CO₂ hydrogenation Since the advent of industrial revolution, the accumulation of carbon dioxide (CO2) in the Earth's atmosphere has raised significant environmental and climate concerns. As a response to this pressing challenge, the conversion of CO2 into chemicals and/or fuels through direct hydrogenation has emerged as a widely recognized and imperative strategy for mitigating both CO2 emissions and fossil fuel consumption.
