SUMMARY:Joseph KIOSEOGLOU (Department of Physics\, Aristotle University of Thessaloniki\, Greece)
DESCRIPTION:Atomistic & AI Discovery of Functional Nanomaterials & Thin Films\nRésumé : \nFunctional nanomaterials and thin films play a central role in emerging technologies for microelectronics\, optoelectronics\, energy conversion\, sensing\, and health-related applications. Their properties are often governed by atomic-scale mechanisms\, including defects\, dopant incorporation\, surface and interface stability\, strain fields\, morphology evolution\, growth pathways\, and phase transformations. In this seminar\, predictive atomistic modelling strategies will be presented as a way to connect these mechanisms with experimentally measurable properties and data-driven materials design. Selected examples will include semiconductors\, oxide materials\, nanowires\, nanoparticles\, low-dimensional systems\, and bio-related/pharmaceutical materials\, with emphasis on first-principles calculations\, molecular dynamics\, interatomic potentials\, machine-learning interatomic potentials\, and microscopy-informed simulations. Recent opportunities opened by artificial intelligence and generative modelling\, including sustainable-by-design materials discovery\, will also be discussed. These approaches enable the exploration of large chemical and structural spaces\, the simultaneous optimization of multiple properties\, and the proposal of experimentally relevant candidate materials. The broader perspective is to show how computation can move beyond interpretation and become part of a predictive\, collaborative workflow integrating modelling\, synthesis\, characterization\, and materials optimization for next-generation functional materials. \nShort Bio/CV\nPr. Joseph Kioseoglou research focuses on atomistic modelling\, first-principles calculations\, molecular dynamics\, machine-learning interatomic potentials\, and AI-assisted materials design\, with applications to semiconductors\, oxide materials\, nanostructures\, thin films\, surfaces\, interfaces\, defects\, nanoparticles\, and bio-related/pharmaceutical materials. He has coordinated and participated in numerous European and national research projects and has extensive experience in doctoral supervision\, international scientific collaborations and conference organization. He has held visiting professor/research positions in France\, Germany\, Japan\, including Grenoble INP/LMGP. \n_ \nContact : deborah.verger@grenoble-inp.fr

SUMMARY:Klaus ENSSLIN (ETH Zürich)
DESCRIPTION:Bilayer graphene : rich in physics and good for devices\nRésumé : \nElectrons have a charge and a spin degree of freedom. The primitive unit cell in graphene honeycomb lattice has 2 atoms. As a consequence\, there is an additional valley degree of freedom in graphene that can be tuned by gate voltages. For electrostatically-defined quantum dots in bilayer graphene this leads to a particular filling sequence\, with the first 4 electrons in the s-shell and the next 8 electrons in the p-shell. The details of the level spectrum reveals many surprises\, such as a singly-degenerate spin-triplet/valley-singlet states for the two carrier state. When building a qubit\, one can utilize all available degrees of freedom: charge\, spin and valley. For the so-called Kramers qubits\, where spin and valley need to be flipped for relaxation from the excited to the ground state\, lifetimes as long as 100 s have been experimentally observed. For graphene layer twisted at the magic angle one can fabricate superconducting devices such as Josephson junctions\, SQUIDs and Cooper pairs boxes. In this talk I will present the prospects that graphene offers to investigate physics questions related to topology\, superconductivity\, spin-orbit interactions and spin-valley coupling as well as device concepts with unprecedented tuning opportunities. \n_ \n\n\n\nATTENTION : Pour accéder au site du CNRS (sans badge)\, envoyez-nous un e-mail plus de 24 heures avant le séminaire.\nATTENTION : To enter the CNRS site (without a badge)\, send us an email more than 24 hours before the seminar.\n\n\n\nContact : equipe-seminaires-nano@listes.grenoble.cnrs.fr

SUMMARY:Laura B. STEREN (Instituto de Nanociencia y Nanotecnologia CNEA/CONICET\, Buenos Aires\, Argentina)
DESCRIPTION:Emergent phenomena at Oxides surface and Interfaces\nRésumé : \nComplex oxides exhibit a rich variety of optical\, electronic\, and magnetic behaviours. When these materials are confined to the nanoscale\, they can display interfacial and size-dependent effects that are not present in bulk materials. The ability to design and fabricate artificial oxide heterostructures with tailored functionalities has therefore made them an important platform within the broader field of quantum materials. In this talk\, I will present our most recent results in oxide spintronics\, describe the main research directions pursued by our team\, and discuss the experimental challenges of controlling these materials at the nanometre scale\, where structure\, interfaces\, and functionality must be precisely managed to advance future oxide-based spintronic technologies. \n_ \nCollege 5B Secretary \nEdmond CHAN \nExternal visitors may ask for a site access to Brigitte Dubouloz (dubouloz@ill.fr)

SUMMARY:Jérémie POSCHMANN (Université de Nantes)
DESCRIPTION:Functional genomics of brain disease : linking regulatory mechanisms\, circulating immune states and clinical trajectories\nRésumé : \nMy research uses func-onal genomics to characterize disease associated molecular states and to understand how they relate to biological mechanisms\, clinical heterogeneity and patient trajectories. I first used functional genomics directly in human brain tissue to identify regulatory alterations associated with disease. In autism spectrum disorder\, genome wide profiling revealed that clinically and genetically heterogeneous patients nevertheless shared convergent changes in regulatory activity. Subsequent studies in other brain disorders showed that this convergence at the molecular level was a recurrent feature and established functional genomics as a powerful approach to resolve disease-associated regulatory states. I subsequently extended this approach to circulating cells\, with the objective of accessing disease associated molecular states in living patients. In severe brain injury and psychiatric disorders\, our studies identified\nimmune and regulatory signatures associated with clinical trajectories and disease severity. These results support the use of circulating immune states to characterize biological heterogeneity beyond conventional diagnostic categories and provide a basis for patient stratification. A complementary programme in genetically defined neurodevelopmental disorders allows us to investigate these molecular alterations in a causal framework. By profiling patient blood cells carrying pathogenic variants in chromatin and proteostasis regulators\, we can connect a defined genetic alteration to its molecular consequences and to disease-relevant cellular pathways. \nTogether\, these studies establish a func-onal genomics framework that links regulatory mechanisms to accessible biomarkers and clinical trajectories in neurological and psychiatric disease. \n_ \nContact : yury.lages@univ-grenoble-alpes.fr ou sebastien.carnicella@univ-grenoble-alpes.fr \n

SUMMARY:Alexandre BERNARD (Walter Schottky Institute\, TU Munich)
DESCRIPTION:Remanent anomalous Hall effect from dual spin-orbit and exchange proximity in graphene heterostructure\nRésumé : \nThe coexistence of induced spin-orbit coupling (SOC) and magnetic exchange fields is predicted to drive graphene into topological phases\, such as the quantum anomalous Hall state. In this talk\, I will discuss the prospect of using monolayer graphene proximitized by WSe2 (SOC) and Cr2Ge2Te6 (magnetic exchange) to reach such “ex-so-tic” states. Low-temperature magnetotransport measurements of the heterostructures reveal a large and gate-tunable remanent anomalous Hall effect (AHE) persisting at zero magnetic field. Combining data analysis over various magnetic field ranges and a simple model\, we explain our findings by an intrinsic AHE regime\, where Berry curvature hot-spots from the interplay of SOC and magnetism dominate the Hall response\, but disorder broadening prevents quantization and a full topological phase transition. These results demonstrate the potential of double proximity effects in graphene-based van der Waals heterostructures as a route toward gate-tunable topological graphene phases and devices based on chiral edge states. \n_ \nContact : florence.levy-bertrand@neel.cnrs.fr \n

SUMMARY:Toyoyuki OSE (Hokkaido University\, Japon​)
DESCRIPTION:Viral strategies for immune evasion targeting the JAK-STAT pathway\nRésumé : \n\nThe capacity of viruses to target and inhibit immune signaling by the principal antiviral cytokines\, interferons (IFNs)\, is critical to the outcomes of infection and disease\, and is mediated by viral IFN-antagonist proteins. We have been working on viral IFN-antagonists from the order Mononegavirales such as genus Lyssavirus (e.g.\, rabies virus) and Morbillivirus (e.g.\, measles virus) that counteract the JAK-STAT system. STAT family members mediate signaling in the JAK–STAT pathway and are activated by phosphorylation at a conserved tyrosine residue\, resulting in dimerization through reciprocal interactions between the phosphotyrosine and a SH2 domain.\nTyrosine-phosphorylated STAT (pY-STAT) then translocates to the nucleus to induce the expression of genes encoding antiviral proteins. Although the active and functional forms of STATs are conventionally considered to be dimers\, STATs can undergo higher-order oligomerization\, which is implicated in regulating transcriptional activity. \nWe presented the cryo-EM structures of the tetrameric form of intact pY-STAT1 in complex with DNA or the P protein of rabies viruses [1\,2]. We explained the molecular architecture of the interactions by which P protein selectively antagonizes phosphorylated\, activated STAT1. This novel binding mode explains previously undefined mechanisms by which P protein inhibits importin binding\, DNA binding\, and the conformational transition of activated STAT1 into its DNA-binding form\, thus efficiently shutting down antiviral signaling. We also clarified that the C-terminal domain of the V protein from measles virus selectively binds to the core-region of STAT2 but not STAT13. We were able to monitor that binding of V and IRF9 to STAT2-core is competitive ; V disrupts a preformed STAT2–IRF9 interaction\, suggesting a new mechanism by which V can prevent type I IFN signaling by preventing STAT1–STAT2–IRF9 (the ISGF3 complex) formation [3\,4]. Taken together\, our findings substantially advance molecular understanding of viral evasion of antiviral immunity\, with high resolution molecular insights having the potential to inform novel intervention strategies for a lethal viral disease. \n1.

SUMMARY:Natali PLANK (School of Chemical and Physical Sciences and the MacDiarmid Institute for Advanced Materials and Nanotechnology\, Victoria University of Wellington\, New Zealand)
DESCRIPTION:Nanowire and carbon nanotube device structures for Biosensors and Artificial Neural Networks\nRésumé : \nCarbon nanotube (CNT) networks offer a particularly attractive platform due to their simple fabrication\, tunable electronic properties\, and ability to be interrogated through multiple electrical contacts on a single chip [1]. Functionalised carbon nanotube and graphene field effect transistors (CNTFETs and GFETs) have been used as the active channel in biosensors\, with the future promise of lab-on-a-chip diagnostics strongly motivating the research [2]. The ability to effectively sense analytes depends on multiple factors\, the conductivity of the platform [3]\, the robustness of the functionalisation and the selectivity and function of the receptor [4]. \nCarbon nanotubes also offer an interesting base platform for neuromorphic computing via physical reservoirs. Physical reservoir computing exploits the intrinsic dynamics of complex materials to perform temporal information processing with low power consumption and minimal training requirements. Disordered networks of memristive nanowires have emerged as promising neuromorphic architectures\, as they can host large numbers of nonlinear junctions that collectively generate rich spatiotemporal dynamics [5-7]. \nHere I will present our recent work on the development of the CNTFET and GFET platforms with aptamers and insect odorant receptors and the different challenges and device constraints we have encountered. I will also present our work on the development of the CNT platform for physical reservoir computing applications. \n[1]      Topinka\, M. A\, et al.
