Projet Pressuriz3D (Horizon Europe, appel à projets 2022)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Information Science and Engineering
Statut du projet : CLOSED

Pressuriz3D aims to advance in the field of pressurized protonic ceramic electrolysis cells (PCEC) with the utilization of advanced fabrication techniques such as masked-stereolithography (MSLA) and robocasting. Aiming to reduce the utilization of fossil fuels on a global scale, the design of systems for hydrogen production via steam electrolysis is fundamental to increase the reliability of renewable energy sources. PCECs are high-temperature electrolysers which use ceramic electrolytes characterized by high protonic conductivity. Compared with other HTEs (e.g., solid oxide electrolysis cells, SOEC), this type of conduction mechanism can significantly reduce the operating temperature of the device (e.g., from 700-900 °C to 300-650 °C respectively for SOEC and PCEC). Additionally, PCECs can produce directly pure hydrogen eliminating the purification process to remove steam necessary for SOECs. Fabrication of a PCEC via additive manufacturing (AM) techniques can significantly reduce production costs and the waste of material during processing, thus boosting sustainability and circularity aspects. complex-shaped electrolyte can be produced increasing the mechanical resistance with the joining materials to maintain the gas tightness of the system (i.e., glass-ceramic sealants). Patterned surfaces coupled with glass ceramic sealants will allow the utilization of pressurized gases, which are expected to significantly increase PCEC performances. Furthermore, geometry modification of the electrolyte membranes, thanks to the fabrication via MSLA printing, can further improve the performance and the hydrogen production rate. A high impact on the future career of the candidate is expected by complementing his current background with new skills in the field of hydrogen conversion, in particular, the design and processing of PCEC and the integration of glass-ceramic sealants for the fabrication of pressurized systems.

Projet LinerFun (Horizon Europe, appel à projets 2024)
Action : Postdoctoral Fellowships - Global Fellowships
Panel : Information Science and Engineering
Statut du projet : SIGNED

Aircraft engines generate significant noise during takeoff and landing, prompting the use of acoustic liners (ALs) in engine nacelles for noise reduction. However, conventional ALs are inadequate for modern Ultra-High Bypass Ratio (UHBR) engines, which require thicker liners to cope with lower fan speeds, resulting in increased drag and design trade-offs. LINERFUN tackles the challenge of designing novel ALs that provide the necessary noise attenuation with reduced size without compromising aerodynamic efficiency. This complex task demands innovative solutions and a deep understanding of AL physics. LINERFUN aims to develop a physics-improved TDIBC (piTDIBC) model using scale-resolving simulations to predict sound propagation in turbulent flows within lined ducts. The piTDIBC model addresses the limitations of existing impedance models, which often fail to capture the intricate interaction between acoustic and aerodynamic phenomena. Due to piTDIBC's efficiency, LINERFUN will drive innovation in AL studies in academia and industry, enabling the conceptualization of ALs that meet the aeroacoustic, aerodynamic, and geometric challenges of UHBR engines. The project fosters interdisciplinary collaboration between Politecnico di Torino, the University of Melbourne, and ONERA, ensuring knowledge transfer among partners. Developing a new AL prototype to address UHBR acoustic challenges could be a significant milestone for the aerospace industry, revolutionizing AL technology and offering advanced tools for designing quieter, more efficient engines. LINERFUN contributes to the broader goals of reducing environmental impact and promoting the sustainability of modern air travel.

Projet SEINE (Horizon Europe, appel à projets 2022)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Chemistry
Statut du projet : CLOSED

Lithium-ion batteries have been known as the main solution to the global demand for energy storage devices. However, the rising cost and limited availability of Li have hindered the further development of these batteries. Hence, the research paradigm has shifted to develop earth-abundant elements-based rechargeable batteries among which, sodium-ion batteries (SIBs) show promising potential. The main challenge in developing SIBs is to prepare anode material with high capacity and long cycle life. The low cost, versatile synthesis methods, and ample interlayer distance of MoS2 (MS) have attracted researchers to investigate the possibility of using it as the anode section of SIBs. SEINE aims to develop two-dimensional-heterostructures using derivatives of MS and graphene (Gr). While the presence of single-layer Gr with low defect density beneath MS enhances the electrical conductivity compared to pure MS, the formation of dopants and defects on N-doped MS and N-doped Gr (a) forms active sites for Na+ adsorption, (b) modifies the interlayer interactions, (c) affects the Solid-Electrolyte Interface evolution mechanism, and (d) promotes the stability of the anode. Each of these effects will be investigated in depth using different physical and electrochemical characterization methods. We believe that SEINE’s outcomes will pave the way to answer fundamental questions regarding the mechanisms which affect the performance of SIBs and hence to develop cost-effective, durable, and high-capacity batteries. Thanks to the experiences obtained in this fellowship, Navid Solati Eskandar will be trained as a scientist with a broad interdisciplinary perspective and expertise in different electrochemical applications. Different steps and tasks of SEINE will be performed via collaboration between Navid and Prof. C. Laberty-Robert at Sorbonne University, Prof. Sarp Kaya at Koç University, and Prof. Ovidiu Ersen at the University of Strasbourg.

Projet NOVITAS (Horizon Europe, appel à projets 2021)
Action : Postdoctoral Fellowships - Global Fellowships
Panel : Information Science and Engineering
Statut du projet : SIGNED

NOVITAS aims to generate novel advances in the mathematical modelling of deployable and ultra-thin structures. They consist of booms and membranes that are first flat and coiled around a cylinder, and then they passively deploy, releasing the elastic strain energy stored during the furling phase. During history, deployable structures were adopted for various space applications, for instance, for telescopes, photovoltaic surfaces and antennas. The adoption of deployable booms allows larger structures to be easily and efficiently packaged for launch and reliably deployed on orbit. Despite the reliability of this kind of structure, there are still some issues to be tackled, including the development of a mathematical model able to deal with the accurate definition of the multiscale three-dimensional stress state and failure identification, the material viscoelastic effects, the effects of new composite materials and the multibody simulation for the deployment phase. We will address these issues with an innovative and interdisciplinary approach that combines theoretical, numerical and experimental investigations. The mathematical models formulated by NOVITAS will be able to accurately describe the nonlinear (mainly geometrical) behaviour that this kind of structure typically show during their services, whereas current models fall short due to their time-consuming analyses. We will compare and validate the numerical results with those obtained by experiments, which consists of the creation of a prototype at the Space Structures Laboratory at Caltech, for the viscoelastic and thermal multiphysics testing and simulation of deployment phases to be simulated with a multibody approach. The developed modelling technique will provide engineers with an efficient way for the design of space structures, consistently with the space-based technological innovation necessary for the always more ambitious needs of our society and to encourage a sustainable European economy.

Projet INTRINSIC (Horizon Europe, appel à projets 2021)
Action : Postdoctoral Fellowships - Global Fellowships
Panel : Information Science and Engineering
Statut du projet : SIGNED

The ability to manipulate excitonic complexes in 2D-materials is of fundamental importance for the development of excitonic based optoelectronic devices operating in low-carrier density, low-power regimes. Correlating locally variable quantities with emission properties of excitonic complexes on sub-diffraction length scale could enable on-demand control of the mutual conversion between excitons and trions. In particular, control over trion density upon photoexcitation in a functionalized 2D-material disclose the possibility to achieve trionic optical gain, that is, a condition of optical gain sustained by the difference between trion and pre-doped electron density. As a peculiarity, trionic optical gain does not require global population inversion common to optical gain mechanisms of conventional semiconductors. Therefore, trion density control could enable optical amplification and lasing at unprecedented low levels of excitation. To this end, we aim to understand the photoexcitation dependent trion formation process, their abundance and stability upon variation of local quantities such as carrier doping, defects density and strain fields in 2D-materials. To pursue this goal we will implement a structural /spectroscopic correlated approach based on hyperspectral nano-imaging and far-field cryo-microscopy of 2D monolayers transferred on a plasmonic nanopillars array with controlled levels of charge doping and strain. Demonstration of trionic optical gain in such conditions will provide the necessary requirement for achieving trionic lasing. Laser feedback will be then realized by engineering the surface lattice resonance of a plasmonic nanopillar cavity to match the trionic peak gain wavelength.

Projet DigEco (Horizon Europe, appel à projets 2022)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Social Sciences and Humanities
Statut du projet : CLOSED

The DigEco project will construct, enrich, and analyze a corpus of 700 francophone novels (from 2000 to the present day) using tools and methods developed in the Digital Humanities. This innovative approach will provide new insights into the influence of ecological discourse on contemporary fiction. Although recent studies argue that the environmental question is changing the novel beyond the thematic focus on ecology, to date, no formal investigations have been conducted on such large corpora. DigEco will thus propose new critical perspectives on the capacity of literature to bring anthropocentrism into question. In order to achieve this objective, the project will be organized around three research axes: biodiversity, places, and nonhuman agency. These three elements are all bound to a shift in the traditional mimetic paradigm of the contemporary novel, diverting attention from a previously-dominant focus on human actions. For each of these research axes, I will enrich the digitized corpus using named-entity recognition technologies and semantic ontologies in order to encode a lexicon in biodiversity and identify toponymies and names of animals and plants. Then, using various computational approaches, I will leverage semantic, lexicometric, and stylometric approaches to answer research questions elaborated through an ecocritical methodology. Using sentiment analysis, I will also study the emotions that characters express about concepts, places, animals and plants. This project bridges two emerging fields in literary research – Environmental Humanities and Digital Humanities – and will constitute the first major study on the possibilities of dialogue between them. It will provide the largest set of data on biodiversity, toponyms and nonhuman agency in fiction in any language – an unprecedented opportunity to question literature’s relationship to anthropocentrism and to look at the contemporary novel through the prism of new tools and interrogations.

Projet Gene-Self-Expression (Horizon Europe, appel à projets 2024)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Life Sciences
Statut du projet : SIGNED

The development of effective gene therapies is hindered by limitations in current delivery methods, such as the use of lipid nanoparticles (LNPs) and extracellular vesicles (EVs). We propose a novel approach to overcome these limitations by constructing a self-organizing minimal system capable of producing therapeutic mRNA. Our system leverages the power of lipid membrane compartments to control and regulate gene expression, mimicking the sophisticated spatiotemporal control found in living cells. Our research will focus on three main objectives: (1) investigating the activity of transcriptional and translational machinery in the proximity of lipid membranes, (2) designing and constructing a minimal system that exhibits spatiotemporal self-organization of gene expression, and (3) developing self-manufacturing platforms for the delivery and development of gene therapeutics. By combining expertise in chemistry, biology, physics, and engineering, we aim to create a highly reproducible and efficient system for producing therapeutic mRNA. This will pave the way for the development of safer, more targeted, and more effective gene therapies, ultimately revolutionizing the treatment of various diseases.

Projet ProtectNPC (Horizon Europe, appel à projets 2024)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Life Sciences
Statut du projet : SIGNED

The nuclear envelope (NE) is a double-membrane structure that encloses and protects the genetic material in eukaryotes. It is intermitted by nuclear pore complexes (NPCs), which form channels across the NE and mediate nucleocytoplasmic exchange. High tension in the NE is known to invoke NPC dilation, involving structural changes of the NPC scaffold. It is unknown to date, which NPC constituents limit maximum dilation to prevent NPC disintegration under high NE tension, and if disintegration of NPCs can result in NE rupture and nucleocytoplasmic mixing. A putative candidate for protecting NPC structure under mechanical strain is the nucleoporin 210 (Nup210). It is upregulated in several cancers, emerging as a biomarker for breast cancer metastasis and important for cellular adhesion and migration. Nup210 mainly resides in the lumen of the NPC-associated NE und forms a luminal ring (LR), which surrounds the entire residual NPC. In the proposed project, I will assess the role of the Nup210 LR in maintaining NPC structure to prevent disintegration and potential NE rupture under mechanical strain. For this, I will apply focused ion beam milling, cryo electron tomography and advanced image processing techniques to control and Nup210 depleted human cells under differing conditions of NE tension. The comparison of NPC structures will reveal how the Nup210 LR contributes to NPC structural integrity on a molecular level. I will further resolve the conformational landscape of the Nup210 LR to determine whether it elastically accommodates NPC dilation and re-constriction. These structural studies will be complemented and functionally validated by analysing nucleocytoplasmic exchange and NE rupture in the presence and absence of Nup210 in cells. The insights into NPC scaffold integrity and the contribution of the Nup210 LR, and the workflows developed in this project will be of great interest to the structural biology, NPC, NE and mechanobiology research communities.

Projet MolPWSupFluid (Horizon Europe, appel à projets 2024)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Physics
Statut du projet : SIGNED

P-wave superfluids of fermionic particles are a crucial subject of study in condensed matter systems, where fermions pair up with nonzero angular momentum and exotic quantum phenomena like Majorana zero mode are predicted to exist. Investigation into the p-wave superfluids not only helps unravel the underlying mechanism of high-T superconductors but also provides insights into the fundamental symmetry of elementary particles. Over the last decade, ultracold quantum gas of polar molecules with controllable long-range dipolar interaction has emerged to be a powerful testbed to investigate such exotic quantum phases. At sufficiently low temperatures, fermionic molecules can pair up with p-wave symmetry and form a many-body BCS state. With the molecular scattering controlled with field-link resonances, the BCS-BEC crossover of diatomic molecules can be achieved. However, cooling of these fermionic molecules to this regime and the detection of their emerging properties remains challenging. The main goal of MolPWSupFluid project is to cool polar fermionic NaK molecules to unprecedentedly low temperatures and study the many-body behavior with strong dipolar interaction including p-wave superfluidity and their crossover to a Bose-Einstein condensate of tetratomic molecules. This project will focus on technical advancements in microwave field control, enabling state-of-the-art evaporative cooling of dipolar molecules and facilitating the precise manipulation of molecular scattering with microwave-induced field-link resonances. With successful cooling of the NaK molecules below the superfluid critical temperature, we will investigate the anisotropic pairing property and the Higgs mode excitation of the molecules with critical velocity and Bragg spectroscopy. Finally, we will investigate the topological property of vortex in the p-wave superfluid and the non-Abelian statistics of Majorana zero modes with braiding operations.

Projet GraPhTra (Horizon Europe, appel à projets 2024)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Mathematics
Statut du projet : SIGNED

GraPhTra aims to advance the rigorous theoretical understanding of phase transitions in random graphs and their universal properties, driven by questions in neuromorphic computing, physics, and epidemiology. We will work on three work packages.  -We introduce a new model for random graphs, that are sampled with local energy considerations, inspired by statistical physics and motivated by material science for neuromorphic computing. We use a Gibbs measure to sample a spanning tree of a graph, and by varying the temperature we thus interpolate between the uniform spanning tree and the minimal spanning tree. We demonstrate that the global structure of Gibbsian trees (in the Gromov-Hausdorff-Prokhorov topology) exhibits a phase transition that is universal across various underlying graphs.  -We find conditions under which the position of the percolation phase transition on random unimodular graphs can be reliably estimated using local information. On the way, we resolve a key conjecture on the limiting threshold for Poisson–Voronoi percolation in hyperbolic space as the density of points goes to 0.  -We prove that the spatial random graph models ‘long-range percolation’ and ‘scale-free percolation’ possess a phase where neighbourhoods grow exponentially, ensuring a well-defined reproductive number for spatial SIR (Susceptible → Infected → Recovered) epidemics, answering a long-standing open question.
