ICONE (Innovative COmpact NEutrons facility) is a project of a French High-Intensity Compact Accelerator-driven Neutron Source (HiCANS) aimed at delivering an instrument suite for the French scientific community at the 2035 horizon. ICONE will produce neutrons by accelerating protons to an energy 25 MeV and impacting them on a Beryllium target. The resulting neutrons will then be moderated to...
The proximity of SrTiO$_3$ to a ferroelectric quantum critical point (FE QCP) has become a promising new branch of the study of quantum critical phenomena. New forms of quantum order have been reported in SrTiO$_3$, different from the quantum paraelectric state via dielectric measurements. The critical point here is associated with a soft optical phonon mode responsible for the ferroelectric...
Solubilization of hydrophobic compounds in water is commonly performed by the addition of organic solubilizers through (i) micellar or hydrotropic solubilization using amphiphilic molecules[1], (ii) co-solvency using water-soluble solvents, and (iii) host–guest complexation using macrocycles[2]. In this study, we show that the...
Nanoporous materials, such as mesoporous silicas (e.g., MCM-41 and SBA-15) and metal-organic frameworks (MOFs), exhibit unique properties that make them essential for various applications, including catalysis, separation, and energy storage. A key aspect of energy storage in these materials is the intrusion of water into their pores, a process that converts mechanical energy into interfacial...
Underground hydrogen storage (UHS) in coal seams presents a compelling opportunity for scalable, low-carbon energy storage, yet the fundamental understanding of hydrogen transport in such complex porous media remains limited. In this study, we explore hydrogen diffusion in coal using quasielastic neutron scattering (QENS), a technique uniquely suited to capturing molecular-scale dynamics of...
HiCANS, High Current Accelerator-based Neutron Sources, is a concept proposed several years ago which aims at revisiting how neutron sources suitable for neutron scattering could be built [1]. The concept of HiCANS relies on technical progress in accelerator technology, neutron moderator design and neutron instrumentation developments to be able to propose a source using a low energy...
