Title: Condensed Matter and Materials Research at Sirius: Status, Access, and New Validation Platforms<\/span>
\n<\/strong><\/p>\n

The fourth-generation synchrotron light source Sirius, operated by the Brazilian Center for Research in Energy and Materials (CNPEM), has established itself as a strategic scientific infrastructure for the Brazilian synchrotron user community. With ultra-low emittance, high stability, and high brilliance across a broad photon energy range, Sirius provides unique experimental conditions for advanced studies in diffraction, spectroscopy, imaging, and coherent techniques.<\/span><\/p>\n

This seminar will present an updated overview of the accelerator and beamline portfolio, with emphasis on operational status, performance, and ongoing expansions within Phase II. Key capabilities relevant to condensed matter physics and materials science will be highlighted, including in situ experiments, probes with high spatial and energy resolution, and multimodal approaches.<\/span><\/p>\n

Special emphasis will also be given to the newly developed Experimental and Technical Validation Lines (EVLs and TVLs), which over the past year have played a central role in instrument validation, the development of new experimental methodologies, and the expansion of scientific opportunities available to users.<\/span><\/p>\n

Finally, the new access model to these capabilities will be presented, highlighting how the user community is submitting proposals for experiments on EVLs and TVLs, as well as the future perspectives for integrating these lines into the regular operational portfolio. These initiatives reinforce Sirius\u2019s commitment to expanding user access, fostering experimental innovation, and consolidating its role as a leading platform for condensed matter and materials science research in Brazil.<\/span><\/p>\n

Title: In Situ Ptychographic X-Ray Computed Tomography of Polymer Membranes at the Nanoscale<\/span>
\n<\/strong><\/p>\n

Porous and dense polymer membranes are well-established technologies for applications such as hemodialysis, gas separation, and, predominantly, for water treatment and desalination. Membrane technology is essential for global clean water production worldwide, as about 70% of all water desalination facilities are based on reverse osmosis using thin-film composite membranes.<\/span><\/p>\n

Advancing these technologies requires a detailed understanding of complex membrane morphology under realistic operating conditions. However, conventional characterization techniques, including scanning and transmission electron microscopy, typically require vacuum environments and sample preparation steps that can alter structures sensitive to hydration and swelling.<\/span>\u00a0<\/span><\/p>\n

In this talk, I will present the application of ptychographic X-ray computed tomography (PXCT) at the SIRIUS synchrotron\u2019s Cateret\u00ea beamline for nanoscale 3D visualization of soft matter in unmodified and hydrated states. PXCT enabled 3D imaging at nanometer-scale resolution of polyamide membranes immersed in water. This as achieved without sample modifications, such as staining, vitrification, or separation from the porous support \u2013 steps which are necessary for analyses with the use of electron microscopy, which lead to altering membrane native structures.<\/span><\/p>\n

The PXCT will be compared to the scanning and transmission electron microscopy, and atomic force microscopy measurements to highlight both the capabilities and limitations of each<\/span><\/p>\n

technique. The demonstrated high-resolution PXCT method can be broadly applied across materials science and life sciences to investigate hydrated soft-matter nanostructures realistically, non-destructively, without modifications, and directly in water.<\/span><\/p>\n

Title: Modelling the tumor metallome in vitro reveals manganese as a unique tumor-promoting element <\/span>
\n<\/strong><\/p>\n

The tumor microenvironment (TME) undergoes significant modifications in cancer progression. The TME is comprised of locally secreted molecules, cells, and metal ions. Metals interact with the cell surface or are internalized, modulating downstream pathways related to adhesion, migration, and proliferation. Our group previously showed that tumor-bearing mice present altered Mn distribution. Mn-exposed tumor cells showed higher proliferation and migration in vitro, associated with changes in cell surface adhesion molecules and glycoconjugates\u2019 distribution. In this work, we modulated tumor cells’ metallome, and evaluated metals internalization, cellular distribution and its early effect on migration using an in vitro model. Cell viability and survival were evaluated using the MTT and clonogenic assays. Metal retention and distribution were assessed with inductively coupled plasma optical emission spectroscopy (ICP-OES) and Synchrotron Radiation induced X-Ray Fluorescence (SR-XRF). Cell migration was evaluated with wound healing assay. Our results show that an early interaction between Mn and the cell surface, probably the negatively-charged glycocalyx, induces morphological changes that lead to increased invasiveness.<\/span><\/p>\n

Title: Interplay of Structural, Optical, and Vibrational Properties in Halide Perovskites
\n<\/strong><\/p>\n

Halide perovskites have a unique combination of exceptional optoelectronic properties and low-cost processing, positioning them as unique materials for next-generation devices. Their most celebrated feature is their remarkable performance in photovoltaics, exhibiting power conversion efficiencies competitive with traditional silicon, but achieved through simple solution processing. Beyond solar cells, their defect tolerance, strong light absorption\/emission across the visible spectrum (tuneable bandgap), and high charge-carrier mobility make them outstanding candidates for LEDs, photodetectors, and X-ray imaging detectors. One of the fundamental scientific challenge\u2014and opportunity\u2014 in this theme lies in understanding the interplay between their structure and optical properties. Unraveling how structural features influence the electronic band structure and subsequent light emission\/absorption is key to optimizing their performance and long-term device functionality. Synchrotron radiation techniques can be employed to investigate halide perovskites by providing high-resolution observations across multiple length scales , studying structures and dynamics, and in situ monitoring of device functions , which can help address outstanding science problems and push forward technological development. In this talk, we will discuss some results involving structural properties obtained by synchrotron radiation, optical and vibrational properties of halide perovskites investigated\u00a0in\u00a0our\u00a0group.<\/p>\n

Title: Probing atomic events during hydrogen storage through state-of-the-art characterization with Synchrotron radiation
\n<\/strong><\/p>\n

The current energy crisis and climate change impose the replacement of the energy matrix by renewable energy sources that has never been more urgent. The pursuit of a hydrogen-based economy, driven by renewable energy sources, holds tremendous promise for addressing the urgent need for sustainable energy solutions. However, the efficient storage and utilization of hydrogen remain significant hurdles. An alternative is the use of nanoparticles for hydrogen storage, but there is still a long and tedious way to go through in order to unveil the complex atomic mechanism behind its interaction with hydrogen in great details. In this talk, it will be discussed some of these atomic events that were investigated using state-of-the-art techniques with Synchrotron radiation like AP-XPS (Ambient Pressure X-Ray Photoelectron Spectroscopy) and AP-GIXS (Ambient Pressure Grazing Incidence X-Ray Scattering).<\/p>\n

Title: Small-Angle X-ray Scattering as a powerful tool to understand nanostructures: from proteins to drug delivery systems
\n<\/strong><\/p>\n

Small-angle X-ray scattering (SAXS) is a widely used technique to study different kinds of systems, like biological samples, colloids, soft matter, and polymers, among others. It can give information about the size, shape, and overall structure of scattering particles both in solution and in solid form. Using SAXS, one can obtain structural information from scattering particle sizes ranging from 1 to a few hundred nanometers. Due to its usability, SAXS is crucial for researchers in physics, chemistry, biology, and materials science, among others. Thus, in this seminar, we will explore some of the features of the SAXS technique. Our goal is to demonstrate, through examples, that SAXS can be used to study, for instance, protein structure, protein-ligand interactions, as well as colloidal nanostructures. At the end of this seminar, we will also present some examples from the literature on how SAXS can be utilized in 4th-generation synchrotrons, along with some examples from the literature.<\/p>\n

Title: Submission and Evaluation of Proposals at LNLS-Sirius: Double-anonymous Review and Overview of the Last Cycle
\n<\/strong><\/p>\n

In this seminar, we will explore the process of submitting research proposals at LNLS-Sirius, with an emphasis on the double- anonymous review model adopted to ensure greater impartiality and fairness. We will present the dynamics involved in this process, the main rules, and guidelines for proponents.<\/span><\/p>\n

In the second part, we will share an analysis of the results from the last submission period, bringing relevant data on cut-off scores, ranking criteria, regional distribution of proposals, and gender representation among researchers. This will be a crucial moment to reflect on the reach and diversity of access to Sirius facilities.<\/span><\/p>\n

Title<\/strong>: Probing soft matter dynamics using X-ray Photon Correlation Spectroscopy (XPCS)
\n<\/strong><\/p>\n

X-ray Photon Correlation Spectroscopy (XPCS) is a coherent X-ray scattering technique that enables the investigation of dynamics by analyzing temporal fluctuations in the intensity of coherent speckle patterns. XPCS can access a broad range of timescales, making it suitable for probing both fast and slow dynamic processes in complex materials. It has provided valuable insights into key questions in soft matter systems, including phase separation in protein solutions, nanoparticle dynamics in biological fluids, colloidal organization during gelation, structural evolution in thermo-reversible gels and relaxation dynamics in polymer electrolytes. Its ability to capture the evolution of dynamics and structure under non-equilibrium conditions makes XPCS a powerful tool for studying phenomena such as phase separation, gel transitions, and assembly\/disassembly processes. This presentation will highlight recent findings on soft matter dynamics investigated by XPCS at the Cateret\u00ea beamline.<\/span><\/p>\n

Title:<\/strong> The Canadian Light Source Synchrotron: Enabling innovation in environmental and earth sciences research<\/p>\n

Synchrotrons produce tunable beams of light used by researchers to understand the structure (imaging) and nature (spectroscopy) of molecules in samples. Synchrotron imaging and spectroscopy can be applied to soil, plant-root-soil systems, and environmental studies from macro to nano-scale with minimal sample preparation. The synchrotron techniques have high detection sensitivity for the molecules of interest compared to laboratory methods due to a combination of a brilliant light source and state of the art detectors.<\/p>\n

The Canadian Light Source holds uniqueness in its combination of beamlines specifically suited for soil and environmental samples characterization ranging from mid-infrared through soft X-rays to hard X-rays. During this talk, examples will be shown on the novelty of combining several synchrotron techniques for in-situ monitoring of plant-soil-root systems, and studying soil health and accumulation of heavy elements in environmental samples.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=”24 Sep” tab_id=”1742213484425-677044ed-e744″][vc_column_text css=””]Speaker: Tim <\/span>Salditt<\/span><\/span><\/strong><\/p>\n

Title:<\/strong> Cytoarchitecture in <\/span>Brilliant<\/span> Light<\/span><\/span><\/p>\n

Understanding of biological matter in physiological and pathological states requires quantification of structures, shapes and networks over a wide range of scales. High brilliance synchrotron radiation makes it possible to map large tissue volumes at cellular and sub-cellular resolution [1]. This enables a shift from cell culture to tissues, organisms and organoids. Here we use multi-scale phase-contrast imaging, exploiting coherent wavefield propagation and advanced phase retrieval [2,3].\u00a0 This enables a new form of fully digital 3D virtual histology [4]. To this end, we discuss optics, phase retrieval, and reconstruction in view of resolution, dose, throughput, and how to find the \u2018needle in the haystack\u2019?\u00a0 How to best exploit the opportunities of 4<\/span>th<\/span> generation synchrotron sources. We give examples for applications in three-dimensional virtual histology and patho-histology, offering new insights into the cytoarchitecture of human organs [4-6], from lung and heart to brain, and the respective pathological alterations. And finally we discuss: <\/span>how to exploit all this data<\/span><\/i>?\u00a0<\/span>\u00a0<\/span><\/p>\n

Title<\/strong>: The use of in-situ X-ray diffraction on conventional and additive manufactured steels<\/p>\n

In-situ X-ray diffraction using a synchrotron source is not just a theoretical concept but a practical tool that is paramount to developing new thermomechanical treatments of structural materials through the study of phase transformation. This versatile characterization technique provides an excellent opportunity to explore science and materials engineering, and more importantly, it offers real-world applications. In this presentation, we aim to provide examples of these applications in different steels to track the austenite reversion, i.e., during tempering in high-carbon, high-silicon bearing, and maraging steels, inspiring hope for the future of our field.<\/p>\n
