Meteorite diamonds, which could be 58% harder than ordinary diamonds, have finally been made in the lab. Scientists have ...

The paper describes how measurements of the spontaneous magnetization of pure specimens of single-crystal close-packed hexagonal and polycrystalline face-centred cubic cobalt have been made over the ...

A team of Chinese scientists may have cracked the secret behind the strange Canyon Diablo diamonds. Hexagonal in form rather than cubic, the process behind how these diamonds formed has, until now, ...

In chemistry, structure is everything. Compounds with the same chemical formula can have different properties depending on the arrangement of the molecules they’re made of. And compounds with a ...

Carbon is in group IV A of the periodic table with atomic number 6, an atomic weight of 12.011, and a density of 2.26. It melts at 3727 C. The stable form of carbon at room temperature is Graphite ...

Cubic core: what is the crystal structure of iron at the centre of the Earth? (Courtesy: shutterstock/Johan Swanepoel) A long-standing debate about the structure of solid iron at the centre of the ...

A new and stable phase of gold with different physical and optical properties from those of conventional gold has been synthesized and promises to be useful for a wide range of applications, including ...

A consistent set of unit cell parameters at various temperatures is not yet available for ordinary ice, but the mean of the most precise measurements leads to a density of 0· 9164 g/cm3 at 0 ° C ...
