Talks

The advent of quantum beam sources, which can generate high-flux high-energy X-rays/neutrons, and the development of advanced instrumentations make it feasible to probe atomic arrangement in disordered materials at atomistic level with a high real space resolution. A combination of quantum-beam diffraction and data-driven structural modeling such as reverse Monte Carlo enables us to study...

80. Structural characterization and reversible laser-assisted modification of chalcogenide photonic media

The super-bandgap laser irradiation of the in situ prepared As-S chalcogenide films was found to cause drastic structural transformations and unexpected selective diffusion processes, leading to As enrichment on the nanolayer surface. Excitation energy dependent synchrotron radiation photoelectron spectroscopy showed complete reversibility of the molecular transformations and selective...

91. Lithium ion transport environment by molecular vibrations in ion-conducting glasses

Talks

Controlling Li ion transport in glasses at atomic and molecular levels is key to realising all-solid-state batteries, a promising technology for electric vehicles. In this context, Li3PS4 glass, a promising solid electrolyte candidate, exhibits dynamic coupling between the Li+ cation mobility and the PS43− anion libration, which is commonly referred to as the paddlewheel effect1. In addition,...
