Graphene and diamonds prove a slippery combination

Scientists at the U.S. Department of Energy's Argonne National Laboratory have found a way to use tiny diamonds and graphene to give friction the slip, creating a new material combination that demonstrates the rare phenomenon ...

Superhard carbon material could crack diamond

(PhysOrg.com) -- By applying extreme pressure to compress and flatten carbon nanotubes, scientists have discovered that they can create a new carbon polymer that simulations show is hard enough to crack diamond. The pressure-induced ...

Scientists make insta-bling at room temperature

An international team of scientists has defied nature to make diamonds in minutes in a laboratory at room temperature—a process that normally requires billions of years, huge amounts of pressure and super-hot temperatures.

Popigai: Russia's vast, untouched diamond crater

In the far north of Siberia, Russian scientists have stepped up research on a once-secret deposit of diamonds whose scale dwarfs anything ever discovered and could turn world markets "upside down".

Some alloys don't change size when heated, and we now know why

Nearly every material, whether it is solid, liquid, or gas, expands when its temperature goes up and contracts when its temperature goes down. This property, called thermal expansion, makes a hot air balloon float, and the ...
