Ceramic metal composites like Narser provide excellent strength and the potential for mass production
Schematic diagram of the preparation process for a knarkar-like ceramette. (Image by Yu et al.). Credit: USTC Mollusks have a sturdy protective shell thanks to the internal knaker structure. A natural nanocomposite, Nacre exhibits excellent mechanical properties through both high strength and toughness. Therefore, Nacre is expected to be applied to fields such as lightweight structural composites and protective equipment.…

Ceramic catalyst uses sodium and boron to drive sustainable industrial reactions
The polymer-derived ceramic method uses transition metal-free, sodium-doped, amorphous SiBN ceramics composed of silicon (Si), boron (B), and nitrogen (N) atoms for small molecule activation and catalysis. was adopted to design and synthesize. The distribution of sodium (Na+) and B sites within amorphous silicon nitride enhances the reactivity of both B and N sites, leading to the formation of frustrated…

‘Living’ ceramic uses bacteria to sense gas and capture carbon
Living porous ceramics for carbon capture and gas sensing. Credit: Advanced Materials (2024). DOI: 10.1002/adma.202412555 A team of materials scientists and chemists at ETH Zurich has developed a way to create a “living” ceramic that can detect traces of formaldehyde and capture carbon dioxide from the air. In their project reported in the journal Advanced Materials, the group developed a…
