Metallic glasses are novel materials with applications in space technology, but also in medicine and the watch industry. To better understand their properties and improve their production, Empa researchers are conducting various experiments on board the International Space Station (ISS) in collaboration with the European Space Agency (ESA).
Metals are versatile materials that surround us everywhere, whether as large structural elements or tiny components in our electronic devices, as robust tools or elegant jewelry. In most applications, they show an ordered crystalline structure, which they almost always adopt when solidifying from the melt. But what happens when metal atoms do
