This internship aims to build upon preliminary work at NIMBE, which confirmed the efficacy of hydrogenated nanodiamonds in the photodegradation of certain PFAS. The project will explore the performance of hydrogenated nanodiamonds of varying sources and elucidate the underlying mechanisms driving the process. Photocatalytic reactions will be conducted using illumination setups equipped with different light sources, and catalytic processes will be mainly monitored via LC-MS.

Le but de ce travail est de synthétiser des matériaux d’électrodes susceptibles d’être utilisés dans les batteries Na-ion. Nous nous intéresserons ici à la famille des NASICON Na3V2(PO4). Les matériaux synthétisés seront finement caractérisés : des techniques classiques telles que la diffraction des rayons X sur poudre (structure cristallographique), des analyses SEM (taille des particules et morphologie). Des mesures par voltamètrie cyclique compléteront ce panel pour étudier les propriétés électrochimiques ces matériaux.

Au sein du LEDNA, des dispositifs miniaturisés intégrant des matériaux poreux ont été développés pour l’enrichissement d’analytes par Extraction sur Phase Solide (SPE). Néanmoins, les systèmes actuellement employés pour la manipulation des fluides au sein du dispositif sont peu compatibles avec des formats miniaturisés et une automatisation, ce qui limite intrinsèquement la simplification et la rapidité d’exécution des protocoles SPE. Dans ce contexte, le stage proposé a pour objectif d’une part de développer un système de contrôle fluidique pour des dispositifs miniaturisés SPE et d’autre part de permettre leur évaluation et optimisation dans des protocoles SPE.

This internship is part of a national project (PEPR “Diadem”) to accelerate the discovery of new materials. The goal is to develop a device for synthesizing nanoparticles in the gas phase, with real-time analysis using Laser-Induced Breakdown Spectroscopy (LIBS) to monitor and optimize their composition during synthesis by Flame Spray Pyrolysis (FSP).
Preliminary tests have already proven the feasibility of analyzing single nanoparticles with LIBS. During this internship, the work will involve improving signal quality, investigating the dependence of the LIBS signal on the size, composition and structure of the nanoparticles, and developing algorithms for automatic identification and quantification.

The subject of this internship is part of a thesis project aimed at finding the best way to integrate carbon nanotubes into laminated composite materials capable of bridging microcracks in the matrix of these composites in order to limit fuel leakage from cryogenic tanks of launch vehicles. Knowing the mechanical and thermal stresses involved, the aim is to demonstrate the effectiveness of CNTs in terms of material damage tolerance. Damage tolerance is directly related to strength and sealing performance.
To achieve this, three ways of integrating carbon nanotubes are considered: 1-Growth of carbon nanotubes (CNTs) directly on carbon fibers by CCVD [2], 2-Transfer of a mat of aligned carbon nanotubes on carbon fiber fabric pre-impregnated with CE, and 3-Random dispersion of carbon nanotubes in the matrix. The materials selected in the three ways will be subjected to mechanical tests.

This project proposes an in-situ study, during the VACNT formation, making it possible to analyze the nature and structure of catalytic nanoparticles, as well as the potential formation of disordered carbon influencing the height limitation of CNTs, is very important. This study will be carried out on a local scale using an environmental TEM (E-TEM NanoMax from the TEMPOS Equipex) to analyze the catalytic nanoparticles and the carbon being formed around individual particles.

This M2 intership aims to develop a bottom-up synthesis of diamond nanoparticles, based on sacrificial templates (silica beads or fibers) on which nanometric diamond seeds will be attached via electrostatic interactions. Diamond growth will be achieved by an exposure of the seeded templates to a micro-wave assisted CVD plasma (MPCVD). Growth parameters will be adjusted to select the size, the shape and the concentration of chemical impurities (nitrogen, boron) in nanodiamonds. After CVD growth, nanoparticles will be collected by dissolution of the templates. Their crystalline structure, morphology and surface chemistry will be characterized at CEA NIMBE by scanning electron microscopy (SEM), X-ray diffraction (XRD) and Raman, infra-red (FTIR) and photoelectrons (XPS) spectroscopies.

The aim of this intership is to investigate the potential of nanodiamonds in producing solar fuels (H2 or CO2 reduction) by photo/electro-catalysis through a collaboration between the NIMBE team (Hugues Girard and Jean-Charles Arnault), which specializes in nanodiamond synthesis and SOLEIL team (Benedikt Lassalle, LUCIA), which has expertise in electrocatalysis and X-ray absorption spectroscopy (XAS) characterizations.

Hierarchical Porous Monoliths (HPMs) have recently proved their relevance to simplify and accelerate sample preparation of glycomics analysis, before detection of oligosaccharides by MALDI-TOF mass spectrometry.
The main purpose of this internship is to standardize the fabrication methods of devices using these materials in a kit form.
