Quantum interference between dark-excitons and zone-edged acoustic phonons in few-layer WS2
...
Fano resonance which describes a quantum interference between continuum and discrete states, provides a unique method for studying strongly interacting physics. Here, we report a Fano resonance between dark excitons and zone-edged acoustic phonons in few-layer WS 2 by using the resonant Raman technique. The discrete phonons with large momentum at t...
In-situ monitoring of changes in ultrastructure and mechanical properties of flax cell walls during controlled heat trea...
Plant fibres are increasingly used as reinforcements, especially in thermoplastic composites. Understanding the impact of temperature on the properties of these fibres is an important issue for the manufacturing of high-performance materials with minimal defects. In this work, the structural evolution and mechanical behaviour of flax fibre cell wal...
Approaching the minimum lattice thermal conductivity in TiCoSb half-Heusler alloys by intensified point-defect phonon sc...
Half-Heusler (HH) alloys based on TiCoSb are becoming popular semiconducting materials for mid-temperature thermoelectric (TE) applications, due to their superior Seebeck coefficient, moderate electrical conductivity, and excellent mechanical properties. However, their practical applicability is mainly limited by their high lattice thermal conducti...
Test Bench Development and Application to a Parametric Experimental Study on the Dynamic Adsorption Capacity of Noble Ga...
The objective of this work is to develop a dedicated test bench to study the dynamic noble gases trapping by porous materials, and especially by MOF, in a nuclear context. The well-known coppercontaining HKUST-1 material is used to determine the influence of different parameters such as 2 temperature, concentration, humidity, MOF bed height or diam...
Electron Beam Processing as a Promising Tool to Decontaminate Polymers Containing Brominated Flame Retardants
...
Electron Beam (EB) irradiation was utilized to decontaminate model systems of industrial polymers that contain a brominated flame retardant (BFR). Acrylonitrile-butadiene-styrene (ABS) and Polycarbonate (PC) are two types of polymers commonly found in Waste Electrical and Electronic Equipment (WEEE). In this study, these polymers were exposed to EB...

Design Rules for the Nano-Bio Interface of Nanodiamonds: Implications for siRNA Vectorization
The enormous therapeutic potential of selective RNA interference has recently been manifested by the approval of several small interfering RNA (siRNA)-based drugs. However, the efficacy of siRNA delivery is still limited, and an extensive search for alternative and highly effective delivery approaches is ongoing. With this aim, three generations of...
VALORISATION ELECTROCHIMIQUE DE L’AZOTE ET DE L’HYDROGÈNE CONTENU DANS L’URINE
...
La majorité de l’azote présent dans les eaux usées est sous sa forme ammoniacale (NH4+) et a pour origine l’urée provenant de l’urine humaine. Sous cette forme ammoniacale, son traitement est réalisé principalement par voie biologique en station d’épuration, nécessitant un apport d’énergie pour l’aération et produisant des formes intermédiaires tel...
Superdense hexagonal BP and AlP with quartz topology: Crystal chemistry and DFT study
The superdense hexagonal phosphides BP and AlP, whose structures are formed by distorted tetrahedra and characterized by quartz-derived (qtz) topology, were predicted from crystal chemistry and first principles as potential high-pressure phases. From full geometry structure relaxations and ground state energy calculations based on quantum density f...
