Scientists have synthesized the first transparent sample of a popular industrial ceramic. The result is a super-hard window made of cubic silicon nitride that can potentially be used under extreme ...

The super-hard window made of cubic silicon nitride can potentially be used under extreme conditions like in engines, researchers said. Scientists have synthesised the first transparent sample of a ...

A harder form of diamond that has eluded scientists for decades can now be synthesised in the laboratory, and could be used to make extremely tough cutting and drilling tools. Diamonds as we know them ...

The brilliantly shiny diamond is more than just pretty; it's one of the hardest minerals on Earth, with a name derived from the Greek word adámas, meaning unbreakable. Scientists have now engineered a ...
