Where diamond has a regular crystal structure, graphene (or at least the Platonic ideal of graphene) is a flat, single-atom-thick sheet of six-sided carbon rings. The hexagonal rings of six carbon ...

Physicists have successfully created a lab-grown diamond with a hardness exceeding that of natural diamonds. By subjecting ...

The interstitial alloy between carbon and iron has a complex phase diagram. A compound, Fe 3 C with the fixed composition Fe-6.7 wt % C bounds one end of this diagram and pure iron the other end. Pure ...

Seljakow, J. Kurdumoff, and N. Goodtzow (NATURE, 119, 494; 1927), that quenched carbon steels contain a phase with a tetragonal crystal structure, which might be considered as a deformation of the ...

The pioneering nuclear chemist Glenn Seaborg discovered berkelium at Berkeley Lab in 1949. It was one of many achievements ...

A new reagent has moved carbon-atom transfer out of the chemical flatlands, allowing chemists to place a single carbon atom so that it makes bonds to four different substituents. The reagent makes ...

A new carbon material known as monolayer amorphous carbon (MAC ... MAC is a composite material that incorporates both crystalline and amorphous regions. It is this composite structure that gives MAC ...

Hydrogen and carbon monoxide travel at different speeds ... and the entire structure incorporated into a crystal structure. The objective was to elucidate how such a solid, rich in platinum ...
