Strain‐dependent electrical and optical properties of atomically thin transition metal dichalcogenides may be useful in sensing applications. However, the question of how strain relaxes in atomically thin materials remains not well understood. Herein, the strain relaxation of triangular WS2 deposited on polydimethylsi…
(weight-average molecular weight) = 102 kg/mol) and PEO (M (molecular weight) = 1000 kg/mol) were selected to optimize the electrospinning process parameters. The PEO powder was solubilized into chitosan solution at different weight ratios in 0.5 M acetic acid. The physicochemical changes of the nanofibers were determ…
Abstract The first structurally characterized copper cluster with a Cu 13 centered cuboctahedral arrangement, a model of the bulk copper fcc structure, was observed in [Cu 13 (S 2 CN n Bu 2 ) 6 (C≡CR) 4 ](PF 6 ) (R=C(O)OMe, C 6 H 4 F) nanoclusters. Four of the eight triangular faces of the cuboctahedron are capped by…
Solubility is a critical component of physicochemical characterisation of engineered nanomaterials (ENMs) and an important parameter in their risk assessments. Standard testing methodologies are needed to estimate the dissolution behaviour and biodurability (half-life) of ENMs in biological fluids. The effect of pH, p…
Abstract Analysis of new, promising wide-band-gap nonlinear crystals for the mid-IR is given. We focused on ternary and quaternary chalcogenides and based on their physical and chemical properties, which in addition to linear and nonlinear optical properties, determine the efficiency of crystal usage in certain laser…
Composite biomaterials as artificial bone graft materials are pushing the present frontiers of bioengineering. In this study, a biomimetic, osteoconductive tricomposite scaffold made of hydroxyapatite (HA) embedded in non-mulberry Antheraea assama (A. assama) silk fibroin fibers and its fibroin solution is explored fo…
Background: The worldwide medicine research is dedicated towards improvement of patients’ health and diseased state. The use of nanotechnology is an upcoming area which is at present, is highly focused in the filed of medicine. Continuous studies in the area have given rise to the development of a novel field called “…
A study of hybrid inverted quantum-dot (QD) light-emitting diodes constructed with and without Al 2 O 3 interlayers is presented. The Al 2 O 3 interlayers are deposited at ZnO/QDs or/and QDs/4,4′-bis(carbazol-9-yl)biphenyl interfaces, resulting in large improvement of device performance, including luminance, current e…
Two-dimensional (2D) phosphorene, which possesses fascinating physical and chemical properties distinctively different from other 2D materials, calls for a fundamental understanding of thermal transport properties for its rapidly growing applications in nano- and optoelectronics and thermoelectrics. However, even the…
There are emerging opportunities to harness diverse and complex geometric architectures based on nominal two-dimensional atomically layered structures. Herein we report synthesis and properties of a new core–shell heterostructure, termed Au@MoS 2, where the Au nanoparticle is snugly and contiguously encapsulated by fe…

In this review, we have briefly summarized the fundamental theoretical models and characterization methods of textile surfaces with special wettability, various fabrication technologies and potential applications.
This paper presents a combined CFD simulation and experimental validation study of emission control strategies for a single-cylinder direct-injection diesel engine. Focus areas include Exhaust Gas Recirculation (EGR), injection timing, and aftertreatment concepts such as Diesel Particulate Filters (DPF) and Selective…

Conduction de la chaleur au phonon sondée au moyen d'une méthode électrothermique impliquant des micro et nanofils déposés The context of this PhD is the reduction of sizes involved in material development and the confinement of heat in modern devices, which are known to lead to the apparition of hot spots. The goal i…
Le travail s’inscrit dans un cadre interdisciplinaire, à l’interface de la chimie sol-gel, la biologie et la physique des matériaux. Nous nous sommes intéressés en premier lieu à l’étude d’une matrice de silice obtenue par le procédé sol-gel à partir d’un mélange de silice colloïdale et de silicates de sodium. Le but…
Dans le cadre du projet ASTRID, le procédé de fabrication du combustible nucléaire par métallurgie des poudres, pour les RNR, est revisité dans le but d’être simplifié. En particulier, nous cherchons à supprimer l’étape de granulation mécanique de la poudre qui lui confère un bon comportement à l’écoulement. La problé…
L’objectif de ces travaux de thèse porte sur l’élaboration et les études photophysiques et physico-chimiques de nanosystèmes hybrides magnétiques et photocommutables. L’association de ces deux propriétés apparaît pertinente pour des applications dans le domaine du stockage de données reposant sur des modulations de l’…
Ce travail de thèse a pour objectif une meilleure connaissance des formulations filmogènes développées par les Laboratoires URGO. Deux aspects ont été développés.Il a tout d’abord été recherché un système d’encapsulation afin de protéger des molécules d’intérêt dans des solutions filmogènes. Des polymersomes en phase…
Développement d'un concept d'agent compatibilisant-traceur réactif visant à étudier l'évolution de la réaction interfaciale et de la morphologie de mélanges de polymères réactifs Le mélange de polymères est une méthode répandue pour élaborer des matériaux polymères.
