Rubber-soil mixtures are known to have mechanical properties that enable their use in backfills, road construction or geotechnical seismic isolation systems. The complexity of these mixtures comes from adding soft (i.e. rubber) particles that increases the number of particle properties to consider when studying the macroscopic behaviour. The distin...
Vacancies are missing atoms in a crystalline material, and occur both at equilibrium (varying with temperature) and out of equilibrium such as when crystalline materials are damaged with radiation or corrosion. While we know of their importance, particularly regarding diffusive mechanisms, it is not straightforward to experimentally measure their c...
Depuis plusieurs années, l'étude des sels chlorures fondus s'est amplifiée dans le domaine de la production et du stockage énergétique. Leurs propriétés physico-chimiques, associées au développement de réacteurs nucléaires de quatrième génération à combustible liquide, permettraient de concevoir des systèmes plus performants en termes de sécurité i...
To harness all of the benefits of solid-state battery (SSB) architectures in terms of energy density, their negative electrode should be an alkali metal. However, the high chemical potential of alkali metals makes them prone to reduce most solid electrolytes (SE), resulting in a decomposition layer called an interphase at the metal|SE interface. Qu...
Liquid-fueled reactors exhibit unusual and interesting properties compared to solid-fueled reactors, requesting a revision of some well-known conception and safety rules. Emphasis is thus put in this chapter on such differences and the need for innovative approaches with the focus on homogeneous molten salt reactors. The molten salt fast reactor co...
Ni-Mn-Ga based alloys are widely studied due to their potential for practical applications, making use of their martensitic transformations. However, hysteresis is a long-standing drawback that reduces the chance of transferring these alloys from the laboratory to industry. In this work, we studied a Cr-doped Ni2.15Mn0.70Cr0.15Ga alloy. We arrived ...
Chiral magnetic domains are topological spin textures in which the Dzyaloshinskii–Moriya interaction assigns a given chirality to the domain walls. Notably, despite rapid progress in chiral magnetic research, one fundamental issue that remains unclear is how the chirality of chiral magnetic domains change as a magnetic field deforms the spin textur...
Over the years, recycled has become one of the most attractive pavement rehabilitation alternatives. Different recycling methods are now available to address specific pavement distresses and structural needs. Recycle the old material offers multiple environmental advantages: a saving of natural materials, a sharp reduction in the traffic of heavy g...
With the rapid development of wearable technology, flexible dielectric materials with environmental-friendly, low-cost and high-energy efficiency characteristics are in increasing demand. In this work, a flexible dielectric nanocomposite was developed by incorporating two components: cellulose nanofibrils (CNF) and recycled alum sludge, as the rein...
NaTaO3 is a stable and wide bandgap n-type semiconductor material with many different applications. Here, a flux-mediated synthesis method is presented for NaTaO3 resulting in highly distinctive, substrate covering shapes via precursor chemistry variation at comparatively low temperatures. It is found that the microstructure of the resulting NaTaO3...
