102. Characterizing Rare Earth Elements at Aqueous Interfaces

Mark Schlossman (UIC)

15/07/2024, 14:05

Keynote

Rare earth elements are utilized in a diverse range of modern and evolving technologies. Current methods for separating and purifying these elements involve their interactions at liquid interfaces. For example, the primary separations technique in current use, known as solvent extraction, involves molecular binding and assisted transport across liquid-liquid interfaces. Other techniques in...

49. Quantitative determination of rare-earth cations distribution at the electrolyte silica interface using x-ray standing waves and molecular dynamics

Oral

A precise understanding of the distribution of chemical species at interfaces, in particular ions, is crucial in many areas.
For example, the so-called Solid-Electrolyte Interface (SEI) plays a crucial role on battery performance.
In a different area, the interaction between ions, humics and minerals plays a key role in the dispersion of pollutants as the modulation of the effective surface...

77. Polymer brush collapse under shear flow

Javier Carrascosa Tejedor (Institut Laue-Langevin)

Oral

Shear is observed in many natural and technological systems, affecting their structure, dynamics, function and performance. Entangled polymers exhibit unique flow behaviours, as relaxation processes occur on time scales relevant to our daily lives, from milliseconds to hours or even days. Investigating the relation between out-of-equilibrium microscopic structure and dynamics of fluids and...

47. Resonant Tender X-ray Scattering and Diffraction for probing soft matter systems

Guillaume FREYCHET (CEA LETI)

15/07/2024, 15:30

Oral

Resonant x-ray scattering and diffraction is an emerging technique for the nanostructure characterization of soft matter. While these approaches are widely spread for highly ordered material, the amorphous or paracrystalline nature of most of the soft matter systems limits the use of currently developed method such as diffraction anomalous fine structure technique.
In this presentation, we...
