A study using neutrons at the MLZ suggests that developing a solid electrolyte, while intentionally leaving the material disordered, will lead to higher battery performance.
A team of German and Dutch scientists synthesised a series of substances, which show bright luminescence under UV light. Therefore the amount of hydrogen in the structure determines the wavelength – and hence the color – of the emitted light. These compounds could be used as illuminants in LEDs or for chemical hydrogen storage.
In a joint publication, scientists from University College London, CEA/University Grenoble Alpes, and LENS members ISIS Neutron and Muon Source, Institut Laue-Langevin (ILL) and Laboratoire Léon Brillouin (LLB), explain how innovations in neutron scattering are enabling researchers to create and test new Polymer Electrolyte Membrane (PEM) formulations for clean-energy applications.
Perovskite oxynitride materials can act as effective photocatalysts for water splitting driven by visible light. A combined neutron and x-ray study now provides unique insight into the underlying processes at the solid–liquid interface and highlights how solar-to-hydrogen conversion can be improved.
