How is a metal formed?

What does it mean to be a metal? How is a metal formed? These seem like textbook questions with a simple answer: Metal is characterized by free electrons that give rise to high electric conductivity. But how, exactly, is ...

Quantum computing boost from vapour stabilising technique

A technique to stabilise alkali metal vapour density using gold nanoparticles, so electrons can be accessed for applications including quantum computing, atom cooling and precision measurements, has been patented by scientists ...

Inorganic perovskite absorbers for use in thin-film solar cells

A team at the Helmholtz-Zentrum Berlin has succeeded in producing inorganic perovskite thin films at moderate temperatures using co-evaporation - making post-tempering at high temperatures unnecessary. The process makes it ...

Solvent-free, catalyst-free way to produce alkali metal hydrides

Researchers at the U.S. Department of Energy's Ames Laboratory have found a way to create alkali metal hydrides without the use of solvents or catalysts.  The process, using room temperature mechanical ball milling, provides ...

New material could advance superconductivity

Scientists have looked for different ways to force hydrogen into a metallic state for decades. A metallic state of hydrogen is a holy grail for materials science because it could be used for superconductors, materials that ...

A water splitter with a double role

(PhysOrg.com) -- There is a lot of hope invested in hydrogen, but it also presents some problems. It is energy-rich, clean and, as a constituent of water, of almost unlimited availability. However, so far it has been difficult ...
