title: Photosynthetic Biohybrid Batteries: A Spectral Energy Transfer Framework

description: The document discusses the design and engineering of artificial photosynthetic systems for energy storage, aiming to create high-efficiency biohybrid batteries. It covers the following key aspects:

 * Theoretical Foundation: The light-to-charge conversion in photosystems is modeled using a Förster-Dexter operator, with a focus on exciton transport and eigenmodes. The dominant mode facilitates coherent exciton delocalization, while the loss mode involves self-trapping at defects.

 * Biohybrid Battery Design: The proposed battery utilizes a cytochrome c_6-coated graphene anode and a Mn_4CaO_5 cluster cathode, with a proton-conducting polymer electrolyte. The design incorporates spectral matching to solar flux to maximize efficiency, with a theoretical maximum of approximately 35%.

 * Degradation Dynamics and Control: The document addresses degradation modes, such as photobleaching, and proposes model predictive control (MPC) strategies to stabilize the system using sensors and adjusting incident photon flux.

 * Performance Metrics: The biohybrid battery is projected to offer advantages over lithium-ion batteries, including higher energy density (500 Wh/kg), faster charging rate (10C), longer cycle life (10^6 cycles), and lower cost ($20/kWh).

 * Experimental Validation: The document includes spectroscopic proof and prototype performance data, showing promising results for current density and stability.

 * Challenges and Solutions: It identifies challenges like exciton recombination, proton leakage, and scalability, and proposes solutions such as plasmonic AuNPs, graphene oxide proton membranes, and roll-to-roll chloroplast deposition.

 * Stability and Scalability Solutions: This section details strategies for stabilizing photosystems outside cells, enhancing bio-abiotic interfaces, preserving quantum coherence, and enabling scalable manufacturing. Techniques include CRISPR-guided mutagenesis, protein encapsulation, graphene quantum dots, and DNA origami scaffolds.

 * Proton-Coupled Electron Transfer (PCET) Optimization: The document explores maximizing energy efficiency by controlling proton-electron synergy, leveraging quantum coherence and operator-theoretic stability analysis.

 * Multi-Proton Tunneling: It discusses leveraging the Coherence Evolution Model (CEM) to exploit collective proton tunneling for ultra-efficient energy conversion.

title: Mechanisms of Se(IV) and U(VI) uptake in chuckanovite (Fe2(OH)2CO3)

description: The aim of the project is to investigate the uptake of Se(IV) and U(VI) in chuckanovite (Fe2(OH)2CO3), an Fe(II)-carbonate hydroxide mineral, which can be formed under redox reducing conditions at the interface between the steel container and the bentonite clay barrier in a high-level radioactive waste repository. The characterisation of synthesised chuckanovite confirmed a 100% of Fe(II) in the structure. Batch sorption experiments, demonstrated that chuckanovite exhibits a high retention capacity for Se(IV) and U(VI) at pH 8.2, even in the presence of carbonates. The high Fe(II) content (which enhances redox reduction) and the presence of structural CO32- (which facilitates anionic exchange) can both contribute to the effective retention of radionuclides (RN). However, the formation of other surface complexes cannot be ruled out. Access to ROBL-BM20 beam line is deemed essential for the surface analysis of Se and U-chuckanovite samples and the understanding of retention mechanisms.

title: In situ Structure Visualization of Direct Air Capture using Metal-Organic Frameworks

description: Implementation of carbon capture technology such as direct air capture (DAC) is highly needed for EU's climate neutral target. The crystalline porous solids, metal-organic frameworks (MOFs), have demonstrated excel potential for DAC. We recently developed a layered copper-based MOF with a crystal structure that features alternating hydrophobic-hydrophilic channels. Our recent simulations on this MOF indicate a unique channel-selective adsorption mechanism of CO2/H2O, where CO2 molecules occupy the water-free hydrophobic channel at high humidity. To evaluate its potential for DAC, it is highly worthy of carrying out in situ adsorption breakthrough experiment coupled with synchrotron X-ray diffraction to understand the binding behavior of competing components in DAC. This information provides direct visualization of the host-guest interactions, and in combination with complementary density functional theory (DFT) calculation can inform the energy profile of adsorption.

title: RIXS investigation of collective charge excitation dependency with doping level for hole-doped BSCCO

description: The versatility of Resonant Inelastic X-ray Scattering (RIXS) in disentangling the properties of elementary excitations is established to investigate the cuprate high-temperature superconductors (CuSC). In these materials, charge and spin degrees of freedom are intertwined and give rise to a complex phase diagram. Here, we propose RIXS experiments of both Cu L3 and O K-edges for 3 compositions of hole-doped Bi2Sr2CaCu2O8+δ (Bi2212) to examine the evolution of spin and charge excitations across the charge-ordered and Fermi liquid regions of its phase diagram. We will probe paramagnon and charge excitations with a focus on the latter, specifically on the evolution of the recently discovered acoustic plasmon branch of the charge excitations in hole-doped cuprates.

title: Characterization of Antimony catalysts inherited from plastic waste during chemical recycling

description: Plastic waste pollution has become a major environmental issue in modern society, increasing the demand for recycling polyethylene terephthalate (PET). Glycolysis process seems the better compromise to recycle PET in an economical and environmental way.In the frame of a PhD project, we study the activity of inherited species, and more specifically Antimony since it is by far the most used polycondensation catalyst for PET.Indeed, Sb is added as an oxide during polycondensation and converted into an organic species that act as a homogeneous catalyst. Therefore, Sb is present in every PET waste streams, and will affect PET chemical recycling.Studies have found that both oxidation states III and V can be found in waste streams, but the link with both species’ activities has not been thoroughly covered. We aim at establishing a clear link between oxidation state of antimony and the catalytically active forms in a glycolysis reaction.EXAFS and XANES are the most fitting analyses for that.

title: The Evolution of Crystallization and Phase Separation Equilibrium in Multi-Component Systems for Spray-Coated Organic Solar Cells

description: The objective of this proposal experiment lies in using in situ annealing experiments on a temporal scale to clarify the correlation between the morphology evolution of complex multicomponent organic solar cells (OSCs) and their device performance, which aims to precise control the phase separation length scales through the manipulation of crystallization, and seek to identify the optimal balance between crystallization and phase separation to achieve efficient and stable organic solar cells. Our motivation is to integrate kinetic and thermodynamic analyses to uncover the transformation from single-molecular packing to multiple-phase-scale changes for the morphological evolution during thermal annealing treatment of thin films deposited by ultrasonic spray-coating and to reveal the complex structure-performance relationships that connect morphological evolution with device efficiency.

title: X-ray reflectivity measurements of µm-sized electrode particles

description: X-ray reflectivity (XRR) nowadays is limited to model surfaces employing mm-sized samples. The extent of real surfaces in applications (e.g.,
Li-ion batteries), which need improved fundamental understanding, however, is several hundreds of nm to tens of µm. Towards this end, we demonstrated the feasibility of XRR in µm -sized model samples employing the nm-sized X-ray beams uniquely available at ID01 of ESRF-EBS. As a next step, we propose to extend our study to samples closer to application, namely spin-coated Al2O3 platelets coated with Au/Ti as a well-known system with clear Kiessig fringes to simulate the distribution of crystallites in electrodes, and real NMC electrode crystallites spin coated in a similar way. This will help to ultimately use nm-beam XRR for in situ experiments utilizing the high-intensity nm-beams at ESRF-EBS.

title: Subcellular distribution and speciation of iron and manganese in pollen grains

description: Manganese (Mn) and iron (Fe) are essential micronutrients for plants, playing critical roles even in reproductive organs of plants, such as the pollen-bearing anthers. Our team has developed single-cell ICP-MS and metal staining methods, which, along with other researchers' work, have demonstrated that the accumulation of Fe and Mn in flowers is genotype, age and growth condition-dependent. Pollen grains are the organs most strongly accumulating Mn that further increases with flower maturation. We have found that mutations in the NRAMP5 transporter, which mediates the efflux of Mn and Fe from the trans-Golgi network, cause defects in pollen transmission (unpublished data). What remains to be determined is the exact location and species of Mn and Fe before and during flower pollination. Our aim is to investigate the distribution and form of Fe and Mn in wild-type and Mn/Fe transporter mutant flowers of Arabidopsis thaliana plants at tissue and subcellular levels using µXRF and µXANES.

title: Subcellular mapping of gold in cancer cells treated with gold(III)-based anticancer drug candidates and correlation with organelle fluoresce

description: A wide range of molecular gold compounds display cytotoxic properties and may in turn provide safer and more efficient alternatives to clinically approved platinum based anticancer drugs. In this context, structure-activity relationship studies we performed on an array of cationic biphenyl gold(III) complexes with a carbene-pyridine chelating ligand showed a marked dependence of both the antiproliferative property and the chemical reactivity on the nature of the C^N ligand. We now wish to examine by nano-XRF the impact of the C^N ligand of 3 representative gold complexes on the distribution and concentration of gold in cancer cells shortly exposed to each of these complexes at biologically meaningful concentration. Correlative fluorescence microscopy of cellular organelles with multicolour staining dyes will warrant precise location of gold and other heavy elements in cryo-fixed cancer cells

title: Strain, induced by magnetron sputtering, as a principal descriptor of activity of Ir-Ru catalyst for water electrolyzers probed by Wide Angl

description: Proton exchange membrane water electrolyzers are essential for the hydrogen economy, yet reducing the cost of anode catalysts remains a critical barrier to mass production. Building on our previous work, where we developed efficient low-loading Ir-Ru catalysts on enhanced proton exchange membranes via thin-film magnetron sputtering, we aim to further explore catalyst behavior. Earlier ESRF measurements revealed that in the Ir-Ru system, Ru leaches from the surface, forming an Ir-Ru@IrOx structure, with alloying also observed. This study will examine whether Ir-Ru@IrOx formation depends on the Ir-Ru ratio or microstructure, influenced by sputtering power. We will investigate the structural evolution of Ir-Ru catalysts prepared at varying powers of the magnetron sputtering.

title: Investigating the synergistic effect of a doping and an electrolyte on the charge compensation mechanism in P2-type cathodes for SIBs using

description: Mn-based layered oxides, commonly used as cathodes in sodium-ion batteries, have limited lifespans due to unstable electrode-electrolyte interfaces, particularly at voltages above 4.3 V, which cause oxygen loss. This study presents an ultra-low concentration electrolyte (ULCE, ≤0.5M) to address these challenges and enhance the high-voltage performance of P2-type Mn-rich oxide cathodes. The research will also examine how cation and anion dopants, combined with ULCE, influence the structural evolution and electrode interphase during sodium (de)intercalation.

title: Viewing stressed defects in Silicon Carbide for Power Electronics

description: The wide bandgap semiconductor material Silicon Carbide (SiC) is an attractive proposition to replace Silicon (Si) for the development of efficient, robust power electronic devices, with commonplace devices only introduced into the market within the last 5 years. In development, is 20 years behind development when compared to Si, with defects which are sources of failure and inefficiency. One major issue in SiC power electronics devices is the long-term reliability. One fundamental, major contributor to variation of device performance over time is the presence of basal plane dislocations in the starting substrate and its expansion and conversion to Shockley type stacking faults. During a test session at the XMaS Beamline (IH-ME-34), a methodology was found to image SiC layers in diffraction mode with high resolution. We propose use this method to image defects that have undergone thermal stress ex-situ to replicate this mechanism so that it can be further understood.

title: Momentum-selective phononic response at ultrafast antiferromagnetic dynamics

description: This proposal investigates phonon dynamics following photoexcitation that demagnetizes antiferromagnetic (AFM) CuO. Using time-resolved magnetic diffuse scattering, we recently clarified that the demagnetization leads to magnon creation in a large reciprocal-space volume and that the magnons spontaneously condense at the Γ point with a spin gap. Further relaxation processes to annihilate magnons are likely mediated by phonon emission, which should be exclusive in momentum (q) because of the energy conservation rule. Therefore, we expect q-selective phonon excitation on the timescale of magnon annihilation. To verify this, we propose performing time-resolved diffuse scattering, witch has both time- and q-resolution. The achievement will allow us (1) to establish the reciprocal-space picture of the recovery process from a photo-created non-equilibrium AFM state, which will form the basis of AFM-based spintronics, and (2) to extract the mode-selective magnon-phonon coupling strength.
