Nanoscale Phenomena & Low-dimensional Materials
HHX-ray and Neutron Methods for In Situ and Operando Studies of Materials and their Processes
Powerful X-ray and neutron sources at large-scale facilities are considered as the ultimate tools for probing microstructure and electronic properties of functional and engineering materials. This symposium covers basic concepts of these sources, studies of materials’ physical and chemical properties, and impact in industry beyond academia.
Scope:
The fast development of advanced materials demands in-depth understanding of physical mechanisms that drive materials formation, processing, and functionality. Recently, remarkable advances at large-scale facilities have been achieved thanks to emerging techniques developed at spallation neutron sources, 4th generation synchrotrons and free electron lasers. The high brilliances, small beam size, high photon and particle energies, short but controllable pulses allow for probing structural, microstructural, morphological and electronic structure at unprecedented levels.
This symposium will gather experts in the field to explore the state-of-art X-ray and neutron-based research for understanding, design, development and validation of next generation engineering and functional materials. The unique source properties at large-scale facilities enable time resolutions down to picosecond timescales, spatial resolution down to the nanoscale, bulk penetration, phase contrast, and spectroscopic distinctions of different materials. They further facilitate in-situ and operando studies during the formation or functioning of materials. For engineering materials, these techniques provide valuable information about crystal phases, chemical species, microstructure, texture, defects and residual stresses. For functional materials, besides the above information, the global and micro-scale electronic structures can also be unveiled at nanometer scale in cooperating with coherent x-ray imaging and spectro-microscopy studies. The scope of the materials science topics and their applications is extensive, encompassing electronic and optoelectronic devices (including flexible ones), transport properties, photovoltaic applications, catalysis, metallurgy, energy related, bio-inspired and structural materials.

- Monitoring materials processing via spectroscopies, microscopies, and photon and particle diffractions
- Advances in numerical tools for data treatment (AI, ML, …)
- Multiscale computer modeling related to synchrotron or neutron characterization
