12. A combined QENS and NMR study of the dynamics of the deep eutectic solvent ethaline

Mr Mohammad Nadim KAMAR (Institute of Physics of Rennes)

Oral

Over the past decade, Deep Eutectic Solvents (DESs) have garnered significant attention within the scientific community due to their remarkable functional properties. Yet their nanoscale organization remains challenging due to nanoscopic domains and dynamics heterogeneity.

We probed the molecular dynamics of the benchmark deep eutectic solvent ethaline, separating the motions of its two...

14. Effect Surface Chemistry on the Properties of Nanoconfined Water

Denis MORINEAU (Institute of Physics of Rennes, CNRS-University of Rennes 1)

Oral

In many natural and technological settings, water exists not as bulk liquid but as thin interfacial films or within nanopores, where its behavior is strongly influenced by surface chemistry. These constraints can significantly alter hydrogen-bonding compared to bulk water, raising the question of whether surface chemistry can be deliberately tuned to control interfacial water properties.

20. On the origin of the non-dispersive mode in glass-forming liquids: the case of squalane

Arantxa ARBE (Centro de Fisica de Materiales (CSIC-UPV/EHU))

Oral

In spite of its fundamental interest, the collective dynamics of molecular liquids and glass-forming systems at the mesoscale –and its relationship with self-dynamics– is still poorly understood [1,2]. Mesoscale means distances long enough compared to intermolecular dimensions but not yet in the hydrodynamic region. Neutron scattering experiments addressing the coherent dynamic structure...

6. Pressure dependent dynamical investigation of relaxations associated with hydrogen bonding in 1-propanol

Mr Anand Kumar TIWARI (Institut Laue-Langevin)

Oral

Hydrogen bonds are ubiquitous in nature and play a central role in determining the microscopic dynamics of liquids. While water remains the most important hydrogen-bonded liquid, its peculiar behaviour and supercooling challenges motivate the study of simpler systems, such as mono-hydroxy alcohols,where hydrogen-bond dynamics are better separated from structural relaxation. Dielectric...

66. Structural relaxation and nano-domain dynamics in highly concentrated electrolytes for zinc anode batteries

Antonio FARAONE (NIST Center for Neutron Research)

Invited

Due to their intrinsic non-flammable nature, aqueous batteries are regarded as desirable alternatives to lithium-ion batteries which use non-aqueous electrolytes. Metallic zinc has long been regarded as an ideal anode material for aqueous batteries systems. Highly Concentrated Zinc Electrolytes (HCZEs) are a new type of Water in BiSalt Electrolytes (WIBSE) which might enable practical zinc...

28. Universal behavior of mesoscopic dynamics in molecular liquids: spectroscopy with polarized neutrons and MD-simulations

Prof. Juan COLMENERO (Centro de Física de Materiales (CSIC-UPV/EHU))

Invited

In spite of its fundamental interest, the dynamics –collective and self—of molecular liquids and glass-forming systems at the mesoscale is still poorly understood. Quasielastic neutron scattering (QENS) is the ideal technique to carry on this kind investigations in a wide Q-range (Q: momentum transfer) due to the high energy resolution available. The problem is that the measured intensity...
