Replacing lithium with sodium in batteries

An international team of scientists from NUST MISIS, Russian Academy of Science and the Helmholtz-Zentrum Dresden-Rossendorf has found that instead of lithium (Li), sodium (Na) "stacked" in a special way can be used for battery ...

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 ...

Unleashing perovskites' potential for solar cells

Perovskites—a broad category of compounds that share a certain crystal structure—have attracted a great deal of attention as potential new solar-cell materials because of their low cost, flexibility, and relatively easy ...

Transparent electronics research gains momentum

Transparent electronics are the future, according to researchers including José A. Flores-Livas and Miglė Graužinytė from the research group headed by Stefan Goedecker, Professor of Computational Physics at the University ...

Why does concrete swell and crack?

Unfortunately, concrete does not last forever. The ravages of time also take their toll on concrete structures in Switzerland. Not only are reinforced structures like bridges affected, but also concrete buildings without ...
