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 ...

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 ...

Transparent oxide glass with rubber-like property

Flexible substances that can withstand high temperatures are much sought after for various industrial and engineering applications. Types of glass made from oxides are hard at room temperature and fracture easily, but scientists ...
