Research
New theory provides answers to why metals have the structures that they do
The simple concept shows that a metal’s structure results from chemical interactions between localised electrons, challenging the traditional free electron gas model
-
Research
Unique molecular state at ultracold temperatures points way to controlling chemical reactions
Deeper understanding of interactions close to absolute zero could also aid creation of exotic quantum matter

What does AI mean for chemistry?
Phil Ball looks at whether letting machines do our thinking for us will change our understanding of chemistry itself
-
Research
Algorithm produces one of the best solutions to molecules’ Schrödinger equations yet
But aggressive ‘pre-training’ actually damages its predictive powers
-
Research
Machine learning massively speeds up scouring of periodic table for stable structures
Algorithm investigated 31 million crystal structures with calculations taking seconds instead of hours
