Scientists are smashing metallic micro-cubes to make them ultrastrong and tough by rearranging their nanostructures upon impact. The team reports that firing a tiny, nearly perfect cube of silver onto ...

ZnO varistor ceramics were synthesised by cold sintering/spark plasma sintering and post-annealing treatment. Intriguingly, the ZnO varistor ceramics present ultrahigh potential gradient, high ...

(Nanowerk Spotlight) The structural materials that are currently used in our human-built environments wear out due to age and damage, and have limited ability to respond to changes in their immediate ...

Ling Li has a lesson in one of his mechanical engineering courses on how brittle materials like calcium carbonate behave under stress. In it, he takes a piece of chalk composed of the compound and ...

For many years, carburising has been amongst the most widely used processes for developing a hard, wear resistant layer on steel components. Fluidised bed furnaces have proven themselves to be very ...
