Abstract: To detect pollutants in the air, we are developing compact, high-performance, lightweight measuring devices. These devices probe the chemical reactivity of gaseous pollutants using colored microbeads [see: Mugherli et al, Lab-on-a-Chip 2020; Guittet et al, Journal of Sol-gel Science and Technology 2023].
Abstract: The subject of this internship is part of a thesis project aimed at finding the best way of integrating carbon nanotubes into laminated composite materials, capable of bridging microcracks in the matrix of these composites, in order to limit fuel leaks from launch vehicle cryogenic tanks.
Abstract: The objective of the internship is to adjust the configurations and experimental conditions for the synthesis of carbon nanotubes (CNT) with respect to the constraints imposed by the environment of a transmission electron microscope (TEM) in order to demonstrate the feasibility of growth under these conditions. The envisaged approach is the implementation of our aerosol assisted chemical vapor deposition (AACCVD) process on the microscope.

Abstract: The aim of this internship is to develop coatings for bipolar plates in PEMFC fuel cells. The coating will have to protect the bipolar plate from corrosion and have suitable surface properties (wettability) to ensure gas and water transport.
Abstract: Porphyrins are aromatic tetrapyrrolic macrocycles that exhibit a wide range of optical, optoelectronic and electrochemical properties. The aim of this project is to synthesize new materials based on porphyrins to take advantage of these properties.
Abstract: The term graphene covers a whole family of materials. In this internship, we propose to build by organic synthesis methods graphene nanoparticles for the study of their optical properties and which can serve as a basic brick for the realization of graphene materials.
Abstract: This internship focuses on advancing nanoparticle synthesis through real-time monitoring using in situ small-angle X-ray scattering (SAXS). The goal is to establish a precise control system for nanoparticle properties by creating an automated synthesis setup with a feedback loop between SAXS measurements and synthesis parameters. The intern will work on synthesizing model nanoparticles (SiO2) with sub-nanometer accuracy, analyzing SAXS patterns, understanding the impact of operational parameters on nucleation and aggregation rates, and ultimately building a feedback control loop for producing nanoparticles with predetermined sizes.
Abstract: A hybrid system consisting of a nanotube encapsulating a light-harvesting system in its inner cavity and a metallic catalytic center on its outer surface will be studied in the context of water photolysis.
Abstract: Les micro/nanoplastiques sont une pollution émergente omniprésente sur le globe. La colonisation des microplastiques par des organismes vivants pourrait favoriser leur transport. Ce projet vise à l'étudier et s’appuie sur l’expertise de deux laboratoires de recherche au CEA Saclay et au LNE (Yvelines).
Abstract: The aim of this Master 2 project is to develop a microfluidic approach to surface modification of extracellular vesicles, to make them stable and non-immunogenic when administered in vivo.
Abstract: Parahydrogen hyperpolarisation is a leading method to increase the sensitivity of Nuclear Magnetic Resonance. This method requires a catalyst which, in solution, impairs spectral resolution. The present internship consists in the synthesis of catalysts grafted onto silica and the relationship between their structures and their hyperpolarised NMR properties.
