SUMMARY:Mechanisms of Pd nanoparticle formation and strong metal-support interaction in Pd/TiO2 revealed by operando XAS
DESCRIPTION:Zoom webinar | Replay on Youtube\nElizaveta KOZYR\,  \nE. Kozyr1\, P. Paciok2\, R. Pellegrini3\, M. Chiesa1\, Elena Groppo1\, L. Mino1\, A. Bugaev4 \n1University of Turin\, Italy; 2Forschungszentrum Jülich GmbH\, Germany; 3ALBAChimet S.p.A\, Italy;\n4Paul Scherrer Institute\, Switzerland; elizaveta.kozyr@unito.it \nUnderstanding the formation of active phases and metal-support interactions is essential for the rational design of efficient photocatalysts. In this work\, Pd/TiO2 catalysts prepared by photodeposition and deposition-precipitation were investigated using a combination of operando synchrotron-based X-ray absorption spectroscopy (XAS) and complementary microscopic and spectroscopic techniques. A custom operando photocatalytic cell enabled in situ monitoring of the Pd photodeposition process\, revealing the formation of single-atom Pd(0) sites as an initial step followed by the growth of ~1 nm Pd nanoparticles with narrow size distribution. Photodeposited catalysts exhibit strong metal-support interaction (SMSI)\, associated with the presence of Ti³⁺ sites at the Pd/TiO2 interface and direct Pd-Ti interactions observed by XAS\, EPR\, and EELS. These features lead to enhanced stabilization of metallic Pd even under oxidizing conditions\, in contrast to catalysts prepared by deposition-precipitation. The results highlight how synthesis pathways govern nanoparticle formation mechanisms and metal-support interactions in Pd/TiO2 photocatalysts. \nAcknowledgements \nWe thank ReMade@ARIE funded by the European Union as part of the Horizon Europe call HORIZON-INFRA-2021-SERV-01 under grant agreement number 101058414 and co-funded by the Swiss State Secretariat for Education\, Research and Innovation (SERI) under contract number 22.00187 for the access to the HR-STEM measurements (ERC\, Julich\, Germany) and XAS measurements at SuperXAS beamline of Swiss Light Source.

SUMMARY:Designing better Metal-Organic Framework catalysts for CO2 conversion:  what characterization teaches us
DESCRIPTION:Zoom webinar | Replay on Youtube (soon)\nAnna LIUTKOVA \nPSI (Switzerland) \nMetal-organic frameworks are increasingly explored as materials that can both interact with CO2 and host catalytic sites for its conversion into useful chemicals. This talk discusses how advanced characterization techniques help reveal how these materials behave under reaction conditions. Using Cu and Zn modified UiO-66 catalysts for CO2-to-methanol conversion as an example\, it illustrates how in situ X-ray methods and microscopy guide the design of better catalytic materials.

SUMMARY:Scalable and longer-lasting bulk metals for public health and infrastructure
DESCRIPTION:Zoom webinar | Replay on Youtube (soon)\nLiliana ROMERO RESENDIZ \nBournemounth University\, UK \nImagine a structural metal that is simultaneously stronger and more ductile (flexible) than conventional options – and can even kill bacteria on contact. This is now possible through heterostructured materials\, which combine soft and hard regions within the same metal to create internal mechanical interactions that enhance overall performance. \nThis talk introduces the design principles of these architectures and explains why they outperform traditional alloys across multiple metrics. Using results from the ReMade@ARI initiative\, I will show how cryogenic deformation triggers a cascade of crystal defect mechanisms that progressively sustain work hardening. \nBeyond mechanical superiority\, heterostructuring can embed antimicrobial functionality into bulk metals without sacrificing durability. These findings open pathways toward scalable\, multifunctional materials for demanding applications: from safer medical devices and water infrastructure to resilient energy systems and cryogenic transport.

SUMMARY:In situ characterization of food and plastic waste carbonized under pressure
DESCRIPTION:Zoom webinar | Replay on Youtube (soon)\nFrancesco D’ACIERNO \nKU Leuven\, Belgium \n  \nIn situ investigations of soft-matter carbonization are essential to connect processing conditions with final carbon structure and function. Here we report time-resolved structural and chemical monitoring of autogenic pressure carbonization of non-recyclable commodity plastics performed directly inside sealed quartz capillaries. We also treated food waste-derived sugars through alkaline and neutral hydrothermal carbonization in water and ionic liquids. By combining synchrotron-grade WAXS and SAXS with in-situ Raman spectroscopy\, and supporting ex-situ XPS surface analysis\, we follow the transformation from disordered organic networks to carbonaceous solids under self-generated pressure in real time.\n\nSAXS reveals the emergence and coarsening of nanoscale porosity and density inhomogeneities early in the heating profile\, while WAXS captures the progressive development of short-range aromatic stacking (broadening and gradual appearance of 002-type scattering). Raman spectra recorded concurrently track the evolution of sp2 domains and defect populations via the D and G bands\, allowing kinetic comparison between plastic and sugar routes. Ex-situ XPS indicates contrasting heteroatom retention: hydrothermal-derived chars retain higher oxygen functionality\, whereas plastic-derived carbons show lower O/C ratios and more pronounced graphitization signatures at equivalent processing stages.\n\nTogether the multimodal dataset supports a unifying mechanism in which precursor chemistry controls the balance between intramolecular rearrangement and intermolecular crosslinking\, setting the pathway for pore formation and aromatic ordering under pressure.
