title: XRD/DRIFTS measurements of metal catalysts

description: Diffuse-reflectance infrared spectroscopy (DRIFTS) of metal catalyst (Fe) will be carried out in the ID15A sample preparation lab using the high-temperature cell and the gas dosing system. The use of bottles of O2 (size &lt;= B5) and inert gas (Ar, He) is envisaged. The same samples will be measured with X-rays using the same setup as CH-7348.

title: Structural Motifs of High-Performance Propane Dehydrogenation Catalysts

description: Direct propane dehydrogenation (PDH) has emerged as one of the most promising approaches to produce propylene. Pt is a commercially used metal for PDH and Sn is the most commonly used promoter for Pt catalysts. The PDH reaction is known to be structure-sensitive, meaning its kinetics depend on the structure of the Pt. However, the optimal type, loading, and impact of the promoter remain unclear due to the lack of guiding principles. We have developed PtSn loaded Al2O3 catalysts with various Pt:Sn ratio, which showed very different propylene formation rate and deactivation rate. Here we apply for the Pt L3 edge and Sn K edge QXAFS study combined with Raman and UV-Visible spectroscopies. This study will measure the evolution of Pt and Sn coordination under H2 activation, propane dehydrogenation and regeneration. Compared with different Pt:Sn ratio will determine the optimal geometric structure of Pt and Sn, providing fundamental understanding to improve catalysts performance.

title: Enhancing Black Phase Stability of CsPbI3 using Dimethylammonium Iodide: Mechanisms and Insights

description: Inorganic CsPbI3, with its 1.7 eV direct bandgap, shows great promise for photovoltaic applications, but its commercialization is hindered by phase instability under ambient conditions. Several strategies, including doping, particle size reduction, and surface functionalization, have been explored to improve stability. Among these, the use of dimethylammonium iodide (DMAI) has shown significant promise in stabilizing the black phase. The stability is influenced by annealing temperature and dwelling time, making it essential to understand the relationship between phase transformation, temperature, and DMAI’s role in stabilization. This study investigates CsPbI3 thin films with varying DMAI concentrations (x = 0, 0.2, 0.5, 0.8, 1, 1.2, 1.5, 2) through systematic in situ (heating-cooling) GIWAXS analysis, ensuring high-quality data for structural refinement.

title: scanning-3DXRD measurement of crack tip orientation-strain states to elucidate ductile fracture mechanisms in 3D printed steels

description: The proposed research aims to characterize the process of plastic deformation and crack tip blunting in polycrystalline alloys made by laser-based additive manufacturing (LAM) using a combination of 3D imaging techniques. Fracture toughness in LAM alloys can be as much as 70% lower than conventional metals, however a mechanistic basis for these behaviors remains unclear. Both LAM and wrought stainless steel 316L (SS316L) polycrystals will be studied by in-situ scanning X-ray diffraction (s3DXRD) and phase contrast tomography (PCT) using the nanoscope station at ID11. The experimental data will give access to the temporal and spatial evolution of crack tip geometry and orientation-strain states to assess the influence of local grain morphology on plastic deformation and crack tip blunting throughout the 3D microstructure during in-situ crack growth experiments of notched samples.

title: Crystal quality analysis of SAG PbTe/CdTe heteroepitaxy for Majorana quantum bit applications

description: This proposal aims to examine the crystal quality of heteroepitaxial selective area grown (SAG) PbTe on CdTe using molecular beam epitaxy. PbTe is a promising material for detecting Majorana bound states, which are essential for fault-tolerant quantum bits. However, high-quality, low disorder heteroepitaxy is required to achieve this. Scanning X-ray diffraction microscopy at the ID01 beamline will be employed to analyse strain and rotation distributions in PbTe samples. Our findings will address key aspects like mask constriction, crystal reorientation during growth, and lattice mosaicity on the quality of PbTe nanowire networks.

title: Study of exsolution mechanism in titanate-based materials doped with Ni, Cu and Fe through in-situ diffraction for Rietveld and Pair Distrib

description: The exsolution method for preparing supported nanoparticles is gaining increasing attention due to its enhanced catalytic properties, extended lifetime, and improved resistance to coking. The selection of the metal is crucially for its catalytic application, making the nature of the dopant(s) in the B-site a key factor in understanding nanoparticle formation.
In the light of the results achieved in our previous experiment CH-6703 (see report), hereby, we propose to investigate the exsolution mechanism in a general system (La0.5Sr0.5)0.90Ti1-xMxO3 where x = 0.10. We will investigate both single-metal M (= Fe) and bimetallic (M'_(x/2) M''_(x/2)) systems involving Ni, Cu and Fe. Diffraction data analysed by Rietveld method combined with Pair Distribution Function will be precious to investigate the structure at atomic level of matrix and exsolved nanoparticles giving a more clear picture of the exsolution process using also bimetallic systems.

title: Determining the redox and mechanism for incooperation of Cs into UO2 nanoparticles via HERFD XANES and EXAFS spectroscopy

description: In the present proposal, HERFD-XANES and EXAFS measurements are sort at BM20 to determine the chemical state and 
mechanism of incorporation of caesium in UO2 nanoparticles. Such nanoparticles are found after a high burn-up time of UO2 and referred to 
as high burnup structures (HBS) which is a part of spent nucleal fuel (SNF). Scanning electron microscopy (SEM) and Powder X-ray diffraction 
(PXRD) measurements suggests incorporation of caesium into the crystal lattice. However, the mechanism for incorporation, particularly the 
local chemical structure is unclear and will affect their stability in SNF disposal scenario, hence HERFD-XANES and EXAFS measurement are 
sought on the U M4-edge and Cs L3-edge to determine changes. This work has implications for the storage and safety of SNF particularly in 
the context of the “instance release fraction” in which caesium is a part of and to draw appropriate conclusions for the storage of SNF.

title: Investigating the Role of Strong Metal-Support Interaction in Enhancing Gas Selectivity: A Study of Copper Catalysts on Cobalt Oxide Nanopar

description: This proposal aims to investigate the Strong Metal-Support Interaction between Cu catalysts of sizes varying from single-atoms to nanoparticles and Co3O4 supports in metal oxide-based gas sensors. While metal catalysts are known to improve sensor selectivity, the mechanisms behind this enhancement remain unclear. By using Extended X-ray Absorption Fine Structure at the Cu and Co K-edges, we will analyze how catalyst size influences SMSI, the reducibility of Co₃O₄, and oxygen vacancy formation under different gas environments. The results will advance the understanding of SMSI, providing key insights for designing more selective gas sensors.

title: Multibeam ptychographic tomography of iron-based clean energy carriers

description: We will use multibeam ptychographic tomography to study iron-based materials as candidates for a carbon-free solid fuel. We aim to obtain sub-100nm resolution over an extended scale (&gt;180um). To accomplish our goal, we will upgrade the current scanning set-up of ID 13 with custom-built optics (multi-lens array) and a fast-acquisition detector (DECTRIS Selun). The obtained tomographic sample reconstruction is an essential step toward understanding material heterogeneity and improving the effectiveness of Fe-based energy carriers.

title: Electronic and structural properties of ferropericlase at mantle conditions

description: Ferropericlase (MgxFe1-x)O is one of the main components of the Earth’s lower mantle as well as other rocky planets. At conditions relevant to the Earth’s lower mantle (MgxFe1-x)O is known to undergo a pressure-induced transition from high spin to low spin state, which is at ambient temperatures at 40-70 GPa. This spin crossover is known to be affected by both temperature and Fe content x.Here, we propose to benefit from the recently installed Von Hamos spectrometer at ID27 to perform simultaneous x-ray diffraction and emission spectroscopy experiments at high pressures and high temperatures using double sided laser heating of diamond anvil cells. The obtained data will be extremely relevant for the understanding of planetary interiors and their evolution.

title: Investigation of intracellular speciation of a series organometallic hemilabile gold(III) complexes

description: Chelating carbene-pyridine based organogold(III) complexes of general formula [(C^C)Au(C^N)]+ present antiproliferative activities from the low micromolar to the submicromolar range. Their mechanism of action is currently being investigated as they are potential anti-cancer agents. We observed a clearly different chemical reactivity and cytotoxicity among members of this family, which was related to the nature of the carbene and the N-donor ligands. We previously demonstrated the possibility to identify the speciation of gold(III) phosphine complexes by cryo-X-Ray Absorption Spectroscopy on beamline BM16[2, 3]. We now apply for beamtime on BM16 to perform cryo-XAS measurements on cancer cells treated with three different [(C^C)Au(C^N)]+ complexes to draw relationships between intracellular speciation, anticancer properties and chemical reactivity. This project is financially supported by ITMO Cancer (project Goldspec no. 23CP039-00).

title: Growth of atomically thin silagraphene (graphene-like 2D SiC) using Cu-Si liquid catalysis

description: We investigate the growth of two-dimensional silicon carbide (2D SiC), also known as Silagraphene. Silagraphene features a honeycomb lattice with C and Si atoms and exhibits a direct bandgap, making it suitable for advanced semiconductor devices and silicon photonic integrated circuits. Leveraging the success of Liquid Metal Catalysis (LMCat) in the growth of graphene, we plan to grow for the first time thin graphitic or single layer SiC using liquid CuxSiy. By performing CVD growth on LMCats we have achieved the growth of micron size crystals of SiC inside molten CuxSiy, thus the thickness of the CuxSiy layer affects the thickness of the SiC. We aim to investigate in-situ the growth of SiC in few atomic layers of liquid CuxSiy, by grazing incidence X-ray diffraction (GIXD), Grazing Incidence Small Angle X-Ray Scattering (GISAXS) and X-ray Reflectivity (XRR). This experimental strategy will allow us to delineate the exact growth mechanisms of 2D SiC and fine tune its growth conditions.

title: Controlling Room Temperature Molecular Magnets: from hard to soft magnetism

description: This proposal uses a comprehensive and rational combination of multiple techniques, such as X-ray absorption near-edge structure (XANES) spectroscopy, extended X-ray absorption fine structure (EXAFS) and X-ray magnetic circular dichroism (XMCD) spectroscopy, to study electronic and magnetic ground states of the new coordination compound produced by the reaction of high pressure ammonia (hp-NH3) with Li0.7[Cr(pyz)2]Cl0.7·0.25(THF) (pyz = pyrazine) . Ammonia molecules can diffuse into the layered structure and coordinate with Cr to form a new coordination compound with proposed formula [Cr(pyz)2(NH3)2]∙nNH3, dramatically altering its physical and chemical properties. Therefore, this proposal aims to shed light on structure-property relationships of the system through the mentioned techniques.

title: Collective charge excitations in Ca2RuO4

description: The goal of the proposed experiment is to characterize the electronic dynamics in the correlated 4d oxide
Ca2 RuO4 (CRO) with inelastic X-ray scattering (IXS). We will measure the dynamical structure factor
S(⃗q, ω) of CRO in the low/intermediate and high q ranges. The former range containts excitations that
contribute to the dynamical screening of the Coulomb interaction and hence are a factor determining the
existence and magnitude of the band gap. By comparing the results with theoretical calculations, we will
be able to analyze the influences of the long and short range parts of the Coulomb interaction on the
electronic structure of CRO and obtain results generalizable to other ruthenates. In the high q regime
we probe the on-site spin-conserving crystal field excitations revealing information on the local electronic
structure.

title: In situ GID and XRR characterization of 2D GaN growth on liquid gallium alloys

description: Liquid metal catalysts (LMCats) are a promising platform for the synthesis and growth of large, defect-free and highly crystalline two-dimensional (2D) materials such as graphene and hexagonal boron nitride. More recently, a larger range of 2D materials have been produced this way, including GaN, which is of high interest for applications in nanoelectronics. With the proposed experiments, we aim at investigating the structure of 2D GaN crystals during their growth on liquid gallium alloys. The in-plane lattice constant, crystallite size and strains of the 2D GaN crystals will be tracked in situ using GID and their thickness, roughness and distance from the substrate using XRR. These experiments will enable to unravel the growth mechanism of 2D GaN on the surface of liquid metals and determine optimized conditions for their growth.

title: Low temperature microfluidics for study of iron complex intermediates

description: Microfluidic mixers present a clear opportunity to use the high flux of modern beamlines without experiencing the side effects of radiation damage, and further allow for data collection on reactive intermediates of metalloenzymes or molecular catalysts under the conditions in which they naturally occur. In order to fully exploit the utility of these mixers, it is necessary to have temperature control such that shorter-lived intermediates can be accessed with X-ray absorption and emission spectroscopies. We propose to commission a cryostat compatible microfluidic mixer for measurement of HERFD XAS and XES spectra. Initial experiments will exploit the known temperature dependence of iron spin crossover complexes to confirm sample temperature in the probing regime.
