Nanomaterials & Scattering (O. Paris)
Lab Equipment Research of the Paris group is focused on the physics of nanostructured materials. Activities include experiments and modeling structure-property relationships of carbons, inorganic nanoparticles, nanoporous materials, and hierarchical biological, biomimetic and biogenic structures. We use particularly in-situ scattering techniques to study nanoscale structure and processes in complex systems such ion electrosorption in supercapacitor electrodes or hydrogen storage in nanoporous materials. Recent projects include:
- Fundamental physisorption mechanisms of molecular hydrogen in nanoporous carbons using elastic and inelastic neutron scattering.
- Ion arrangement and dynamics during electrosorption in charged electrodes based on nanoporous materials using in-operando X-ray and neutron scattering.
- Capacitive water de-ionisation using charged nanoporous carbon electrodes by time- and position-resolved X-rays scattering.
- Adsorption and phase-behavior of fluids in confined geometry of nanoporous materials and their sorption induced deformation.
- Hierarchical plant tissues used as a framework to create casting molds for novel nanostructured inorganic materials (Biotemplating)
- Structure-function relations of biomineralized- and cellulosic tissues
- Structural and crystalline properties of colloidal nanoparticles
- Nanostructure and nanomechanical properties of carbons
We focus on the advancement of in-situ and in-operando small-angle scattering techniques using Lab X-ray instruments as well as synchrotron radiation (SAXS) and neutron (SANS) facilities, and we develop new data analysis concepts and data simulation tools. With this we are able to observe changes occurring on the nanometer scale in “real time”, i.e., we are “watching nanomaterials at work”.
