Abstract: L'objectif du stage est d'ajuster les configurations et conditions expérimentales de synthèse de nanotubes de carbone (NTC) au regard des contraintes imposées par l’environnement d'un microscope électronique à transmission (E-TEM) de manière à démontrer la faisabilité de la croissance dans ces conditions. L’approche envisagée est l’implémentation de notre procédé de dépôt chimique en phase vapeur assisté par un aérosol (AACCVD) sur le microscope.

Abstract: Here will consider the study of the optical properties of chirality sorted nanotube devices. First, we will be interested in a drastic reduction of the distribution in chirality. Then, we will study the characteristics of the trapped excitonic states.
Abstract: This project is based on the study of bioleaching processes involved in the recycling of metals found in printed circuit boards (smartphones, laptops, etc.). During this internship, it will be proposed to take control of the current microfluidic platform, on which liquid-liquid extraction processes are tested. The aim will be to integrate the tools and instruments needed to monitor the experimental parameters related to bioleaching processes on the existing platform.
Abstract: The corrosion of metallic structures represents a cost estimated at about 4% of the world GDP. A new strategy based on the analysis of the permeability of anti-corrosion coatings, such as the one developed in our laboratory, can find its place in the many sectors whose products are impacted by corrosion. The proposed internship focuses on the development of this analysis method to make it compatible with the targeted industrial use. Translated with www.DeepL.com/Translator (free version)
Abstract: The main mission of the student will be to integrate in electronic and optoelectronic devices, two-dimensional semiconductor materials (thickness <1 nm) synthesized in the laboratory and to measure their performances. These materials are monolayers of MoS2, WS2 and/or SnS2 synthesized by CVD and analyzed by different techniques (AFM, SEM, XPS, Raman, Photoluminescence). The devices are mainly field-effect transistors based on functionalized 2D materials or based on combinations of several 2D materials.
Abstract: The electrodeposition is widely applied in industry to recover metals from waste electrical and electronic equipment (WEEE). The main objective of this research internship is to demonstrate a viable electrochemical approach to recover metals in a non-aqueous environment.

Abstract: In the context of an European project HARMLESS (for new tools to guide and evaluate the toxicity of new nanomaterials with increasing complexity), this intership aims to optimize the synthesis of metal nanoparticles/clays composites with a safe-by-design approach.
Abstract: Plastic pollution is a major issue, as much for its potential impact on human health as on ecosystems and the environment. Microplastics, non-biodegradable and persistent, are a new global pollution that must be characterized on all size scales, from the nanometer to the millimeter, in order to control and limit the risks of exposure for humans and to allow the implementation of clean-up strategies. There is currently no standard methodology for the identification and characterization of nanoplastics and microplastics smaller than 10 µm in solution. The aim of this internship is to develop a multi-instrument methodology dedicated to the analysis of these sub-micrometer scale objects.
Abstract: The aim of this internship is dedicated to the synthesis of functionalized lipid-polymer nanoparticles by microfluidics.
Abstract: This project in the field of green chemistry proposes to simulate at the atomic scale the hydration mechanism of benzonitrile in aqueous phase at 80 °C in the presence of a non toxic catalyst. The theoretical approach chosen couples ab initio molecular dynamics and metadynamics.
