Exploring the structures of xenon-containing crystallites

20-Aug-2024 - Noble gases have a reputation for being unreactive, inert elements, but more than 60 years ago Neil Bartlett demonstrated the first way to bond xenon. He created XePtF6, an orange-yellow solid. Because it’s difficult to grow sufficiently large crystals that contain noble gases, some of their ...

Sodium-ion batteries: How doping works

Three years of experiments at BESSY II, PETRA III, and SOLARIS

23-Feb-2024 - Sodium-ion batteries still have a number of weaknesses that could be remedied by optimising the battery materials. One possibility is to dope the cathode material with foreign elements. A team from HZB and Humboldt-Universität zu Berlin has now investigated the effects of doping with Scandium and ...

AI agent helps identify material properties faster

High-throughput X-ray diffraction measurements generate huge amounts of data - The agent renders them usable more quickly

21-Apr-2021 - Artificial intelligence (AI) can analyse large amounts of data, such as those generated when analysing the properties of potential new materials, faster than humans. However, such systems often tend to make definitive decisions even in the face of uncertainty; they overestimate themselves. An ...
