Facing the challenging task of developing lightweight, high-strength ceramic materials, an engineer has turned to an unexpected collaborator for design inspiration: the knobby sea star from the ...

The porous (Ta0.2Nb0.2Ti0.2Zr0.2Hf0.2)C high-entropy ceramic possesses interconnected microspheres, abundant interface in the microspheres, and the severe lattice distortion of the high-entropy ...

Exploiting the open, irregular structure of micro-porous ceramic, the MPCHS heat sinks provide a greater surface area to contact with the air compared to metal. The material structure, in turn, ...

The trick here was to use an “ink” consisting of a stable ceramic emulsion that did not collapse during or after printing. Using this technique, it is possible to manufacture complex porous structures ...

Ceramics often have microstructure and grain sizes that affect material performance. It is possible to optimize microstructure and grain boundaries with ceramic processing parameters for specific ...

Although ceramics are known for being able to withstand high temperatures, they also have a reputation for being brittle – they typically shatter when deformed. That's not the case, however, with a ...

Ceramics are lightweight and hard, but you can’t make jet engines out of them because they’d shatter like dinner plates. So, materials scientists have been trying to mimic natural materials that ...
