SUMMARY:Amaury PATIN (Expert in Organic Chemistry\, Nestlé Institute of Food Safety & Analytical Sciences (NIFSAS)\, Lausanne\, Suisse)
DESCRIPTION:The Journey of an Organic Chemist : What Organic Chemistry trains you for— From Drug Discovery toFood (Safety)\nRésumé : \nOrganic chemistry plays a central but often under-recognized role in addressing complex industrial challenges that extend well beyond molecule synthesis. In this seminar\, I will describe how training in organic chemistry can be leveraged across multiple industrial domains\, based on my career spanning academia\, biotech\, and industrial research within a multinational food company. \nThe talk presents a personal career journey illustrating the diversity of opportunities available to organic chemists. Starting from doctoral and postdoctoral research in organic chemistry\, I moved into medicinal chemistry within a biotech startup before joining Nestlé Research\, where organic chemistry became a central tool for addressing challenges in ingredient innovation and food safety. \nThrough selected case studies\, I will show how the same fundamental chemical concepts — reactivity\, molecular structure\, metabolism — can be applied in very different contexts\, from drug discovery to food safety. The seminar will also address the evolution from hands-on scientist to project manager and group leader\, highlighting the importance of soft skills such as communication\, interdisciplinarity\, and leadership. \n_ \nContact : sandrine.py@univ-grenoble-alpes.fr

SUMMARY:Hamid KELLAY (Laboratoire Ondes et Matière d'Aquitaine\, Bordeaux)
DESCRIPTION:From active particles to flexible\, deformable\, and motile superstructures : a new type of soft robot of robots\nRésumé : \nWe study assemblies of rodlike robots made motile through self-vibration. When confined by circular scaffolds\, dilute assemblies of these rods act as a 2D gas of particles. Above a critical surface fraction\, some of the bots line up in one or more tight clusters along the corral boundary while\, in the bulk\, gas-like behavior is retained. We find that the unified pushing of the clustered bots on the boundary can drive collective motion: by selecting corrals that are deformable but free to move\, we take advantage of surface cluster formation to force the robots to work together. The deformability of the arena allows the assembly to go through narrow slits or to circumvent obstacles. Simple tasks such as pulling a load\, moving through an obstacle course\, or cleaning up an arena are demonstrated. Rudimentary control of these superstructures (robots+scaffold) using light is also proposed. \n_ \nContact : jean-louis.barrat@univ-grenoble-alpes.fr

SUMMARY:Bo PENG (Cavendish Laboratory\, University of Cambridge)
DESCRIPTION:Designing molecular quantum materials from first principles\nRésumé : \nQuantum materials provide the basic building blocks for quantum hardware\, but it remains challenging to design robust\, tuneable and scalable material platforms. In this talk\, I will present strategies for engineering quantum materials based on molecular building blocks using first principles calculations. Molecules provide more tuneable building blocks than atoms [1\,2]\, which can self-assemble into larger structures [3\,4] with richer structural behaviours [5] for practical quantum devices. Using pure-carbon fullerene molecules that were believed to be non-magnetic [6]\, we show that magnetism in this material family can be induced purely by symmetry [7]. We can then use this pure-carbon magnetic material to design various quantum platforms\, based on experimentally synthesised monolayers [8\,9]\, to realise exotic quantum phenomena such as ferromagnetic Chern insulators [10]\, antiferromagnetic spin chain [11]\, altermagnetism and quantum spin liquid [12]\, as well as magnetoelectrics where spins can be controlled by electric fields. If time allows\, I will also discuss my ongoing research that combines both atomic and molecular building blocks. With this approach\, we can unlock even more exciting applications such as portable quantum timekeeping\, robust quantum sensing\, and programmable quantum simulations.\n\nReferences:\n[1] BP*.

SUMMARY:Oded ZILBERBERG (University of Konstanz)
DESCRIPTION:Entanglement-based observables for quantum impurities\nRésumé : \nQuantum impurities exhibit fascinating many-body phenomena when the small interacting impurity changes the physics of a large noninteracting environment. The characterisation of such strongly correlated nonperturbative effects is particularly challenging due to the infinite size of the environment\, and the inability of local correlators to capture the buildup of long-ranged entanglement in the system. Here\, we harness an entanglement-based observable—the purity of the impurity—as a witness for the formation of strong correlations. We showcase the utility of our scheme by exactly solving the open Kondo box model in the small box limit\, and thus describe all-electronic dot-cavity devices. Specifically\, we conclusively characterize the metal-to-insulator phase transition in the system and identify how the (conducting) dot-lead Kondo singlet is quenched by an (insulating) intraimpurity singlet formation. Furthermore\, we propose an experimentally feasible tomography protocol for the measurement of the purity\, which motivates the observation of impurity physics through their entanglement build up. \n– \nContact : simon.zihlmann@cea.fr

SUMMARY:Arnaud CLAUDEL (CNRS - Institut Néel)
DESCRIPTION:Growth of graphene by CVD and transfer on various substrates\nRésumé : \nGraphene is a monolayer of sp² carbon atoms which forms a stable\, continuous and gas-impermeable membrane. It also exhibits several exceptional properties (electrical conductivity\, optical transparency\, …)\, making it a candidate of interest for various research topics and applications (transparent electrodes\, detection of chemical or biochemical compounds\, …). Since its discovery in 2004\, graphene has paved the way for two-dimensional (2D) materials\, which are currently the subject of extensive research. For over 15 years\, Institut Néel has been developing and optimising processes for the growth of graphene by chemical vapour deposition (CVD) as well as for transferring these layers onto foreign substrates for a wide range of fundamental and applied research projects. Graphene growth process by CVD and the different forms of graphene (monolayers\, multilayers\, single crystals\, …) will be described. Graphene transfer onto different types of materials will be presented in the frame of various research projects. \nShort Bio/CV \nArnaud CLAUDEL has a MSc (2006) and PhD (2009) in materials science and engineering from Grenoble INP. With 20 years of R&D experience in materials science\, he has been previously R&D project manager in both a company (ACERDE SAS – 2006-2012) and research institutes (CEA-LITEN – 2012-2013\, LMGP – 2014-2015) within fundamental and applicative research projects with academic and industrial partners. Since 2016\, he is CNRS research engineer and since 2021\, manager of the Epitaxial and thin layers (EpiCM) technological group at Institut Néel. His research activities are dedicated to processes for growing epitaxial and thin layers and are mainly focused on the growth and transfer of graphene layers since 2019. \n_ \nContact : deborah.verger@grenoble-inp.fr

SUMMARY:Julien GABELLI (LPS\, Université Paris-Saclay)
DESCRIPTION:Direct Surface Plasmon Detection using Kinetic Inductance Detectors\nRésumé : \nWe present a new kind of on-chip surface plasmon polariton (SPP) detector based on kinetic inductance detectors (KIDs). Our device combines a hybrid NbTiN-Al microwave resonators architecture\, where aluminum serves not only as a photon absorber but also as a plasmonic material. The characteristics of this new detector are demonstrated by detecting optically excited surface plasmon polaritons (SPPs) at a wavelength of 1.5 µm. Notably\, our detector enables direct observation of quasiparticle diffusion in aluminum\, providing new insights into non-equilibrium dynamics at the nanoscale. By detecting SPPs from inelastic tunneling in Al/Al₂O₃/Al junctions\, this work opens new approaches for probing current fluctuations at optical frequencies. \n_ \nContact : florence.levy-bertrand@neel.cnrs.fr  \n

SUMMARY:Vladimir ZAKHAROV (Leiden University)
DESCRIPTION:Luttinger liquid and mass generation on a lattice\nRésumé : \nThe helical edge of a quantum spin Hall insulator hosts a one-dimensional metallic state with spin-momentum locking\, realizing a helical Luttinger liquid (HLL). While the gapless phase is well understood analytically through bosonization in its simplest form\, more complex questions that demand numerical treatment\, have remained largely inaccessible to address for a long time. The core obstacle is the fermion-doubling problem: any local and symmetry-preserving discretization of the Hamiltonian on a strictly one-dimensional lattice either introduces spurious low-energy modes or lifts the Dirac point\, breaking the topological protection of the cone.\nIn this talk I describe how this obstruction can be circumvented using a tangent fermion discretization. This preserves time-reversal symmetry and spin-momentum locking at the lattice level\, without invoking a two-dimensional bulk. I present the application of this method first to the gapless HLL\, where numerical results are in quantitative agreement with bosonization predictions\, establishing the framework as a reliable numerical tool. And then I turn to interaction-induced mass generation\, including spontaneous time-reversal symmetry breaking in HLL and symmetric mass generation in 3-4-5-0 model\, where full analytical treatment is out of reach. \n_ \nContact : serge.florens@neel.cnrs.fr

SUMMARY:Mark GLOVER (Department of Biochemistry\, University of Alberta\, Edmonton\, Canada)
DESCRIPTION:Mechanism of sRNA recognition and regulation by FinO RNA chaperones\nRésumé : \nThe FinO family of RNA chaperones regulate sRNA function throughout gram negative bacteria. Many of the best characterized family members bind to rho-independent transcription termination structures at the 3’ ends of sRNAs and mediate pairing of the sRNA with their mRNA targets. The crystal structure of the FinO domain of the Legionella pneumophila chaperone RocC bound to its sRNA target reveals a novel interaction that recognizes both the stem and the 3’ end of the terminator structure. The structure suggests a mechanism by which different FinO proteins can selectively bind RNAs with different 3’ tail lengths\, which is likely conserved throughout the FinO family. Biochemical and in vivo studies indicate that intrinsically disordered regions adjacent to the FinO domain are also essential for sRNA regulation\, by remodeling RNA structure to facilitate RNA-RNA association. \n__ \nHôte : Dr Nicolas Coquelle (IBS/Groupe Dynamique et Cinétique des processus moléculaires) \nRappel : L’accès au campus EPN nécessite un avis de rendez-vous.

DESCRIPTION:Development of a Sustainable Passive Atmospheric Water Harvesting Device\nRésumé : \nWater is essential for human life\, yet roughly two billion people worldwide still lack access to safely managed drinking water. With increasing pressure from rapid population growth and climate change\, there is a critical need for water generation technologies that are low-cost\, scalable\, and environmentally sustainable. Passive atmospheric water harvesting offers a promising solution by capturing moisture from the air without continuous energy input\, but current approaches are often limited by low efficiency or high cost. This study aims to optimize a bioinspired mixed-wettability surface to enhance passive water collection by promoting both droplet nucleation and rapid transport of condensed water. The surface is fabricated using superhydrophobic zinc oxide nanowire (NW) arrays synthesized via a scalable sol-gel/chemical bath deposition method\, followed by functionalization with a non-fluorinated silane agent. Hydrophilic silica nanoparticles are then deposited on the superhydrophobic NW arrays to create the mixed wettability effect. Material performance is optimized by varying NW morphology\, surface wettability\, and nanoparticle concentration to maximize water collection rates. To induce condensation without energy input\, this mixed-wettability surface is coupled with a passive daytime radiative cooling (PDRC) coating composed of bicontinuous interfacially jammed emulsion gels (bijels). These porous polymer films exhibit high solar reflectance and strong infrared emissivity\, enabling sub-ambient cooling. The PDRC layer is optimized by adjusting domain size and film thickness to achieve maximum cooling performance. In parallel\, a life cycle assessment (LCA) is conducted to evaluate the environmental impacts of material fabrication and identify key contributors to categories such as global warming potential\, water use\, and ozone depletion. This integrated approach informs design choices that minimize environmental burden. The results of this study show promise in developing a material with the ability to passively collect atmospheric water even in climates with low levels of humidity\, potentially aiding in providing clean water globally in the face of the climate crisis. \nShort Bio/CV \nI am a PhD student at the LMGP lab studying passive atmospheric water harvesting technologies. I hold a Bachelor’s degree in Chemical Engineering and a Master’s degree in Sustainable Engineering for International Development from Villanova University (Pennsylvania\, USA). During my master’s\, my research studied the impact of climate change on drinking water resources in Madagascar\, combining data from the latest IPCC climate models with local stakeholder knowledge and priorities to plan for future climate-related water challenges. In 2025\, I spent four months as an invited researcher at the SMART LAB at the University of Pennsylvania\, where I researched passive daytime radiative cooling coatings. My current research builds on this background\, focusing on the development of environmentally sustainable\, low-cost\, scalable materials for passive water collection. \n_ \nContact : deborah.verger@grenoble-inp.fr

SUMMARY:Soutenance de Thèse de Thomas BRUN (IRIG / Spintec)
DESCRIPTION:MAROT : Un magnétomètre miniature pour l’exploration spatiale\nRésumé : \nCette thèse porte sur la réalisation d’un magnétomètre dans le but de mesurer les fluctuations de champ magnétique dans les plasmas spatiaux du système solaire. Des magnétomètres de type Search-coil et Fluxgate sont couramment embarqués sur des satellites et produisent des mesures de haute qualité. De nos jours\, la recherche utilise de plus en plus de petits satellites dont l’archétype est le « Cubsat » qui est un cube de 10 cm de côté. Cependant\, l’instrumentation actuelle ne peut pas être miniaturisée sans compromettre les performances. C’est dans ce cadre que le projet MAROT propose l’élaboration d’un magnétomètre miniature utilisant comme élément sensible des jonctions tunnel magnétiques (MTJ)\, pour mesurer des champs de l’ordre du picotesla. Les jonctions tunnel magnétiques sont des éléments convertissant une variation d’aimantation en variation de résistance\, permettant ainsi de mesurer les variations de champ magnétique. Ces magnétomètres sont déjà utilisés comme capteurs dans de nombreuses applications (automobile\, imagerie médicale\, capteurs dans des systèmes électroniques…) de par leur haute sensibilité au champ magnétique. Cependant\, les MTJ souffrent d’une perte de détectivité à basse fréquence car leur bruit évolue inversement à la fréquence du signal mesuré. Or les basses fréquences (< 100 Hz) sont les fréquences pertinentes pour les plasmas spatiaux. Pour compenser cette limitation\, le capteur MAROT contient des concentrateurs de flux (FC) pour amplifier le champ magnétique sur la jonction. L’optimisation du capteur passe d’une part par l’augmentation de sa sensibilité et d’autre part par la diminution du bruit\, afin d’atteindre une détectivité de l’ordre du pT/√Hz à 10 Hz. Les jonctions tunnels sont constituées d’un empilement constitué de plusieurs blocs : couche de référence\, barrière tunnel\, couche libre. Dans ma thèse\, j’ai utilisé et réalisé des jonctions tunnels à réponse symétrique\, présentant un état antiparallèle à champ nul\, obtenu après un recuit sous champ. Cet état\, ainsi que la configuration macrospin de la couche libre\, minimisant l’hystérèse\, est réalisée en piégeant légèrement la couche libre par une couche antiferromagnétique. Lors de cette thèse\, tout d’abord\, j’ai pu avoir accès à une couche libre à base de FeCoSiB\, couche plus amorphe et plus douce que le NiFe précédemment utilisé\, permettant une amélioration du rapport de magnétorésistance (TMR) d’un facteur supérieur à 2\, jusqu’à 250%. Ces optimisations ont permis de gagner un facteur 3 dans la sensibilité des jonctions. Dans un second temps\, j’ai réalisé des simulations de l’amplification du champ magnétique par les concentrateurs de flux (gain) en fonction des dimensions et caractéristiques de l’entrefer. Cette étude m’a permis de dessiner un nouveau design de capteur dans lequel des jonctions en série-parallèle sont ajoutées dans l’entrefer afin d’augmenter le volume magnétique\, pour réduire le bruit\, tout en maintenant un gain suffisant. Des capteurs avec ce design ont été fabriqués. Les premières mesures indiquent des sensibilités très grandes\, de l’ordre de 2000 %/mT. Les mesures de bruit sont en cours\, et semblent indiquer que les FC\, à base de NiFe déposés par électrolyse\, apportent du bruit supplémentaire. La composition de ces FC sera donc à optimiser afin d’améliorer la détectivité\, actuellement autour de quelques centaines de pT/√Hz à 10 Hz. Pour finir\, j’ai commencé à développer une méthode de hachage de champ magnétique pour réduire le bruit. Une couche magnétostrictive\, déposée sur un substrat piézoélectrique soumis à une tension\, peut voir sa direction d’anisotropie modifiée. Ce dispositif pourra être placé au-dessus de l’entrefer des FC et utilisé comme un interrupteur magnétique\, qui alternativement modifie le flux magnétique sur les jonctions. Un gain d’un facteur au moins 10 sur la détectivité est attendu\, ce qui permettra de s’approcher de l’objectif du pT/√Hz à 10 Hz. \nPlus d’information :https://www.spintec.fr/phd-defense-marot-a-miniature-magnetometer-for-space-exploration/ \nPour suivre la soutenance ​​​en visioconférence : https://univ-grenoble-alpes-fr.zoom.us/j/98769867024 \n_ \n\n\nP​resential access to the conference room at CEA in Gre​​noble requires an entry authorization\, request it before may 16th​​ to admin.spintec@cea.fr
