title: Topological magnetic heterostructures under moire superpotential

description: Dirac fermions on the surface of topological insulator (TI) are spin-momentum locked and topologically protected, making them perspective for spintronics and quantum computing applications. Creating moiré superlattices could dramatically enrich the physics of TIs, analogously to the new phenomena observed in twisted graphene layers. This project is devoted to the study of moire-modulated electronic structure of MnBi2Te4, Bi2Se3 and Bi2Te3 with transition-metal dichalides trilayers on top. The main aim of the project is to unveil the low energy band structure near the Dirac cone replicas crossing points, study the minigaps opening, reveal the renormalization of the Dirac fermions and possible van Hove singularities. Our observations will provide a new way to correlated topological phases, that may result in topological superconductivity, high-Chern number phases and, finally, topologically-protected quantum computing.

title: Structure of magnetosomes suspensions in the presence and absence of magnetic fields.

description: Using iron oxide nanoparticles (IONPs) for cancer treatment has been proposed for the last twenty years. The goal is to target tumors accurately to avoid damage to healthy cells of patients. Once targeting is achieved, the application of an alternating magnetic field heats nanoparticles locally, a phenomenon referred to as magnetic hyperthermia, which can directly kill tumoral cells. Among the large body of developed IONPs, magnetosomes that are synthesized by magnetotactic bacteria (MTB) present definite advantages: such particles indeed display a homogeneous size distribution and uniform morphology are composed of high crystallinity magnetite and/or maghemite, and their magnetic moment is stable at room temperature. The aim of the proposed experiment is to use the capabilities of the MISTRAL beamline to image the structures formed in various suspensions of CA-coated magnetosomes with increasing volume fractions subjected or not to magnetic fields of increasing intensities. We should be able to quantify with excellent statistics the various chaining features of the magnetosomes, which can structure as flexible chains, rings, branched structures or a combination of them depending on the magnetosome concentration and the evolution of these structures upon application of a magnetic field. This should provide new insights on the relationships between structure and heating power features.

title: Experimental search for spin splitting in the electronic states of a newly discovered Altermagnet Fe1/4NbS2

description: Altermagnetism was recently identified as a new type of magnetic phase beyond the conventional dichotomy of ferromagnetism (FM) and antiferromagnetism (AFM). Its globally compensated magnetization and directional spin polarization promise new properties such as spin-polarized conductivity, anomalous Hall effect, tunneling, and giant magnetoresistance that are highly useful for next-generation memory devices, magnetic detectors, and energy conversion. The layered intercalated transition metal dichalcogenide (ITMD) Fe1/4NbS2 has been recently identified as an altermagnet, exhibiting A-type antiferromagnetic order (TN =150 K) with spin-split bands. Our study aims to utilize high-resolution and spin-resolved angle-resolved photoemission spectroscopy (Spin-ARPES) to directly probe the spin-split electronic band structure and Fermi surface topology of Fe1/4NbS2. These measurements will provide crucial experimental validation of the predicted altermagnetic state and offer insights into its electronic and spin properties, paving the way for novel spintronic applications.

title: Elucidation of the mechanism for the alcohol electrochemical oxidation on Ni-based catalysts: an operando X-ray absorption spectroscopy approach.

description: In Recent years, we have investigated a series of Ni-based electrocatalysts for the alkaline oxygen evolution reaction (OER) and alcohol oxidations reactions (AOR). We have well-stablished that the catalytic activity trend for the OER is NiS2>Ni(OH)2>NiO=NiCo2O4. However, this trend is reversed for the AOR. Based on operando XAS, we have found that all catalysts reconstruct under OER conditions to form the actual catalytic species NiOOH; however, the higher catalytic activity of NiS2 for the OER has been correlated with a smaller Ni-O and Ni-Ni bond length of the in-situ formed NiOOH, which may result from the formation of Ni4+ species. These species have been suggested to play an important role in the AOR in a ‘potential-dependent oxidation’ mechanism proposed for Ni oxide-based catalyst, which contrasts a more traditional ‘indirect oxidation’ mechanism on NiOOH. In this context, we propose conducting operando XAS to gain insights into the formation of NiOOH during the ethanol oxidation reaction on NiS2, Ni(OH)2, NiO and NiCo2O4 electrodes. NEXAFS and EXAFS at the Ni K-edge will be measured to monitor the chemical and structural changes of the in-situ formed NiOOH under OER and EOR conditions, aiming to confirm the potential mechanism of EtOH oxidation in these Ni-based catalysts, and explain the catalytic activity trends observed in our studies.

title: ENHANCING AUDITORY SKILLS OF NON-PHILOLOGICAL UNIVERSITY STUDENTS THROUGH CLIL: THE CASE OF AGRICULTURAL EDUCATION

description: In non-philological higher education institutions, developing students’ auditory (listening) competence in English remains a significant pedagogical challenge, particularly in professionally oriented contexts. Content and Language Integrated Learning (CLIL) has emerged as an effective approach that combines subject matter instruction with foreign language learning. This article examines the potential of CLIL in enhancing the auditory skills of non-philological university students, with a specific focus on agricultural education. Drawing on CLIL methodology, second language acquisition theory, and ESP principles, the study adopts a qualitative-descriptive research design involving theoretical analysis, classroom observation, and pedagogical experimentation. The findings indicate that CLIL-based instruction using agricultural content significantly improves students’ listening comprehension, terminological awareness, and motivation. The study concludes that CLIL is an effective pedagogical framework for developing auditory competence in non-philological higher education settings.

title: Establishing a multi-scale imaging pipeline on single human cells by correlative cryo-SXT and high-resolution cryo-ET towards understanding of translation regulation

description: Translation is the process of protein synthesis conducted by the ribosome. Ribosomes distributed across the subcellular space exhibit compositionally and functionally heterogeneity, and in association with ribosome-associated proteins, regulate protein production under varying cellular states. Translation regulation is thus critical to cell homeostasis, and when perturbed, can activate stress response pathways that determine cell survival or death. Understanding how cells respond to stressors at multiple scales, from the level of subcellular organelles (including the ER) to the level of conformational states of the translational machinery, is required and demands the development of multi-scale, label-free, correlative imaging pipelines for the characterization of pristinely-preserved specimens.


Here we aim to combine our strong in house expertise in advanced cryogenic electron tomography (cryo-ET) to visualize large macromolecular complexes inside intact cells at near-atomic resolution, with cryogenic soft X-ray tomography (cryo-SXT) for imaging of subcellular volumes at nanometer-scale resolution. While cryo-ET and cryo-SXT can be performed on human cells vitrified on the same cryo-ET grids, it remains unclear whether the dose spent for generation of high signal-to-noise cryo-SXT data is compatible with high-resolution structural analysis by downstream cryo-ET. In this project, we aim to I) systematically characterize and optimize cryo-SXT imaging conditions which minimally deteriorate the resolution in downstream cryo-ET structural analysis of ribosomes in vitrified cells and II) analyze and correlate the volumetric cryo-SXT and cryo-ET captured on native and translationally-perturbed cells. Cryo-SXT experiments at the MISTRAL beamline at ALBA can be conducted on cells frozen on cryo-ET compatible grids, thereby enabling subsequent correlative cryo-ET on the same specimens and for the first systematic characterization of the effect of cryo-SXT beam damage on the attainable resolution in downstream structural analysis by cryo-ET, leading to the establishment of a multi-scale correlative cryogenic imaging pipeline for exploration of fundamental molecular pathways in health and disease states.

title: Electronic and spin properties of the chiral topological semimetal YPt2B

description: Chirality is attracting growing interest in condensed matter physics, as it establishes unconventional magnetic ordering in skyrmions and helimagnets, as well as unique spin textures in reciprocal space. The distinct symmetry combinations exclusive to chiral crystals are at the core of a new chapter in topological materials, where novel Weyl fermions and surface Fermi arcs emerge in the band structure of chiral semimetals. This proposal aims at investigating the electronic and spin properties of a newly synthesized chiral semimetal, YPt₂B. We will leverage the unparalleled experimental capabilities of the LOREA ARPES setup, equipped with a state-of-the-art electron analyzer with efficient spin detection, and a high-photon-flux source with a small spot size, which is crucial for studying non-layered compounds. The feasibility of this project is supported by preliminary results obtained at LOREA.

title: Electronic band structure of ABC-stacked trilayer graphene and its tuning

description: Multilayer graphene has attracted intensive investigations since the ground-breaking realisation of superconductivity in magic-angle twisted bilayer graphene. Most recently, people realise that even with the non-twisted multilayer graphene, many interesting complex collective behavior, especially superconductivity, can be achieved upon applying external fields and doping. 


Specifically, the ABC (or Rhombohedral)-stacked trilayer graphene has a cubic dispersion in low energy with a flat band near the Fermi level, which serves as an ideal platform for achieving interaction-driven collective phenomena, including superconductivity and ferromagnetism. However, the ABC-stacking phase is less energy-favored than the ABA-stacking phase. Up to now, most fabricated ABC-stacked trilayer graphene flakes are tiny (less than 5 * 5 μm^2) and usually mixed with the much larger ABA-stacked flakes, making the high-quality ARPES measurement on its band structure difficult. 


Using a specific exfoliation method, our collaborator succeeds in fabricating large area ABC-stacked trilayer graphene (around 50 * 50 μm^2). The thicknesses of different regions are measured with AFM and labeled. The stacking order and sample quality have been characterized with Raman scattering and SNOM.


At LOREA, the spatial scan mode measuring either the band near the Fermi level or core levels combined with big-data analysis techniques (clustering and principle component analysis) has been developed and used to detect regions with different thicknesses.


With the help of the small beam spot size (20 * 15 μm^2) and the spatial scan mode, we hope to identify the ABC-stacked regions and further take high-quality ARPES data on its band structure, understanding better the electron-electron and electron-phonon interactions in this system and providing important insights to its unconventional superconductivity.

title: Strain control of magnetic domain structures in altermagnet hematite

description: In this proposal, we aim to investigate the effect of strain on the domain structures of altermagnetic hematite. Strain is expected to alter the direction of the Néel vector due to magnetoelastic coupling. A key objective of this study is to explore how strain-induced absolute changes in the Néel vector affect the XMCD signal. We anticipate that applying uniaxial strain in a specific direction could induce a transition from an altermagnetic to an uncompensated state in hematite, which would be observable through a comparison of XMLD and XMCD signals. Subsequently, an external magnetic field or current pulses could drive domain wall motion via the net moment in the uncompensated system, ultimately enabling monodomainization in hematite. By analyzing domain structure imaging and XMCD signal variations when applying strain, we aim to gain a comprehensive understanding of how strain influences the Néel vector and different magnetic sublattices in altermagnets. This insight is crucial for advancing the fundamental understanding of altermagnetism and its potential applications.

title: Accurate localization of SARS-CoV-2 ORF3a in cellular sub-compartments

description: Viral accessory proteins are believed to play roles in the viral life cycle and may contribute to the pathogenesis and virulence. We have developed in vitro models and implemented tools that include bronchoalveolar A549 epithelial and monocyte THP1 cells individually expressing accessory proteins by lentivirus transduction. SARS-CoV-2 ORF3a is a unique membrane protein with unclear localization and still under discussion function. Our tomograms obtained at MISTRAL through previous proposals (2022025607, 2023027348) have revealed a catastrophic cellular landscape (in both, A549 and THP1 cells), with a high percentage of seriously affected mitochondria, an unusual increase of lipid drops, almost no signs of Golgi or ER and, an increased number of vesicles (some of them with tubular structures). Here we propose to use cryo correlative microscopy (cryo3DSIM combined with cryo-SXT) for the accurate determination of the topological relationship between GFP-labelled ORF3a with the distribution of organelles inside the cells compared to GFP transduced control cells
