Look Inside a Chemical Reactor

Research Using Synchrotron Light Materials Research Matter and Material

Operando X-ray spectrotomography allows scientists to look inside of functioning chemical reactors. A research team at Karlsruhe Institute of Technology (KIT), at Paul Scherrer Institute PSI and at the European Synchrotron Radiation Facility (ESRF) in France have employed this method successfully.

Operando X-ray diffraction during laser 3D printing

Ultra-fast operando X-ray diffraction experiments reveal the temporal evolution of low and high temperature phases and the formation of residual stresses during laser 3D printing of a Ti-6Al-4V alloy. The profound influence of the length of the laser-scanning vector  on the evolving microstructure is revealed and elucidated.

Inside Batteries

Lithium ion batteries (LIB) are essential in modern everyday life, with increasing interest in enhancing their performance and lifetime. Secondary particles of Li-rich cathode material were examined with correlated ptychographic X-ray tomography and diffraction microscopy at different stages of cycling to probe the aging mechanism.

Moving Atoms by Photodoping

Understanding how and how fast we can drive atoms to create a structural phase transition is of fundamental interest as it directly relates to many processes in nature. Here we show that a photoexcitation can drive a purely structural phase transition before the energy is relaxed in the material that corresponds to a “warmer” equilibrated state.
