Under normal conditions, pure water is an almost perfect insulator. Water only develops metallic properties under extreme pressure, such as exists deep inside of large planets. Now, an international ...

MIT physicists and colleagues have created a new material with unusual superconducting and metallic properties, thanks to wavy layers of atoms only billionths of a meter thick that repeat themselves ...

Conductive organic materials often derive their electronic properties from highly organized crystal structures. Now, researchers have developed an organic polymer that conducts electricity like a ...

Scientists have used diamond anvils to compress hydrogen into a form they believe is metallic. In Nature, researchers from the French Alternative Energies and Atomic Energy Commission (CEA) describe ...

A computer simulation shows metallic alloy where atoms (colored spheres) are arranged in subtle chemical patterns beneath a network of dislocations (green lines). These tangled defects move during ...

Newly published results offer compelling evidence that hydrogen is a metal at extremely high pressures. But is the research enough to convince the field at large that metallic hydrogen exists?
