Tools coated with diamond film (diamond-coated tools) are used for difficult-to-machine materials such as CFRP. In the manufacture of diamond-coated tools, a pretreatment is required to remove cobalt ...

Research teams from Wuhan University and the China University of Geosciences (Wuhan) have revealed new insights into the formation mechanism of nitrogen-vacancies (NV) centers in type-Ib diamonds, a ...

The graphite found in your favorite pencil could have instead been the diamond your mother always wears. What made the difference? Researchers are finding out. How molten carbon crystallizes into ...

Diamonds form deep within the Earth’s mantle under pressures above 5 GPa and temperatures exceeding 900 °C. Their genesis is governed by interactive processes within peridotitic and eclogitic domains, ...

Friction between amorphous carbon surfaces transforms wear debris into diamond and graphene while maintaining exceptionally ...

Watching Diamond Formation in Real Time Earlier work using mass spectrometry indicated that single-electron ionization could help break C-H bonds, but that method could only infer structures in the ...

Molten carbon can crystallize into diamond or graphite, but it has been difficult to study this process. New simulations show that graphite can sometimes "hijack" the pathway that would lead to ...
