Higher education and research

Public university with strong focus on natural sciences, engineering, and advanced microscopy.

UK EPSRC-funded research programme focused on fundamental science of metal atoms and clusters at surfaces and interfaces for sustainable technologies.

This is an advanced microscopy technique that uses a specially designed transmission electron microscope operating at low accelerating voltages and often with liquid cells or ultrathin supports to image materials and reactions in real time at near‑atomic resolution, while reducing beam‑induced damage.[1][2][4] In the Pt–Ni study, a SALVE‑type low‑voltage TEM with graphene supports was used to directly visualize the mixing, separation, and oxidation of atoms within individual nanoclusters as they evolved toward catalytically active structures.[1][2]

Electrochemical water splitting is a process in which water molecules are split into hydrogen and oxygen gases by applying an electrical potential across two electrodes, with the hydrogen evolution reaction (HER) occurring at the cathode and the oxygen evolution reaction at the anode.[6] It is a cornerstone technology for producing green hydrogen when powered by renewable electricity, and its efficiency strongly depends on the performance of the electrocatalysts used at each electrode.[6]

The process of using electrical current to split water molecules into hydrogen and oxygen, requiring a stable catalyst to function efficiently.
