Cryo-EM has revolutionized structural biology, allowing researchers to study the structure and function of proteins and other macromolecules at an unprecedented level of detail. It has been used to determine the structure of a wide range of biological molecules, including proteins involved in DNA replication and repair, bacterial flagella, and viruses such as Zika and HIV. Cryo-EM has also been instrumental in the development of new drugs and therapeutics, as understanding the structure of a molecule can provide insights into its function and potential vulnerabilities that can be targeted with drugs.
Although cryo-EM has become a powerful tool for determining the structure of biological molecules, there are still important proteins that present challenges for this technique. Some of the main factors include, size, flexibility, heterogeneity, low abundance. Despite these challenges, cryo-EM is still an extremely valuable tool for studying the structure of biological molecules, and researchers continue to develop new techniques and methods to overcome these challenges and push the boundaries of what is possible with this technique. In this session, we will invite several scientists and discuss about methods to overcome these problems and get valuable information how biological molecules operates.

Quantitative imaging of dynamic biological processes has now become mission critical in the molecular and cell biology. Recent research has repeatedly demonstrated that a combination of state-of-the-art optical imaging technology and advanced image analysis are crucial for the understanding of the numerous and complex cellular processes underpinning human health and disease. Novel developments such as advanced super-resolution imaging is currently transforming how the function and behaviour of cells can be observed in a minimally invasive manner while unfolding within their tissue micro-environment across scales of space and time, shaping thus the expectation that these technologies will replace conventional imaging technologies. Crucially, the analysis and interpretation of these new imaging modalities require advanced image analysis expertise. This symposium will bring together leaders in both super-resolution microscopy and appropriate quantitative analysis techniques.

Structure determination of large and rigid biological macromolecules using single-particle electron cryo-microscopy (cryo-EM) has been accelerating at ever increasing speeds and can now be considered routine. The cryo-EM analysis of small and more flexible molecules with conformational and/or compositional heterogeneity still poses a challenge to the structure determination workflow. Therefore, methods in improving all aspects of the structure determination pipeline from sample preparation up to validation are still required to make a larger repertoire of isolated molecules amenable to the cryo-EM method. High-resolution electron imaging of lamellae generated from vitrified biological cells is also becoming established. While electron cryogenic tomography (cryo-ET) is often employed to image the cellular and subcellular structures at intermediate resolution, it can now resolve near-atomic resolution structures of large macromolecular complexes in situ in the genuine native environment.

[ Topic of Interest ]
• Cryo-EM of molecules of high complexity

Physical Science
Over the last two decades, we have witnessed a paradigm change in the way we understand structure-function relationship of diverse classes of nanomaterials by development of advanced TEM. The spatial and energy resolutions have been significantly improved. Aberration-corrected TEM has enabled a large variety of in-situ experiments, multi-modal imagings, and multi-dimensional data acquisitions with high spatial resolution. For example, in-situ imaging and spectroscopy techniques, both in gas and liquid phase, have emerged as primary tools for characterizing the dynamics of nanomaterials, that can not be fully understood via ex-situ bulk measurements. The exploitation of direct electron detectors in combination with novel data analytics and machine learning is now opening the possibilities for studying beam-sensitive nanomaterials.
In this symposium, we will cover a wide range of topics where the use of advanced electron microscopy, such as aberration-corrected TEM, cryo-TEM, in-situ TEM, 4D-STEM, monochromated spectroscopies, and multi-dimensional imaging in a combination of machine learning, elevates fundamental understanding of structure-function relationship of nanomaterials. Material systems focused in the symposium include, but not limited to, nanoparticles, energy-conversion nanomaterials, energy-storage nanomaterials, and soft-nanomaterials.
The goal of this symposium is to bring researchers together from the microscopy community and nanomaterials society to seek for an opportunity to accelerate materials discovery.

[ Topic of Interest ]
• High- spatial/energy resolution and multi-dimensional imaging for nanomaterials
• In situ TEM for structural evolution of nanomaterial
• Development of advanced TEM methodologies for unprecedented characterization
• Nanoparticles, energy-conversion/energy-storage nanomaterials, and soft-nanomaterials

The structural characterization of carbon-based nanomaterials and 2D materials calls for electron microscopy imaging and spectroscopy at low primary voltages to avoid or minimize knock-on damages to the pristine structures. Pushing the spatial resolution to the atomic-scale and the sensitivity to the single-atom level has thus become one of the frontiers of electron microscopy. Thanks to the continuous development of aberration correction, it is now feasible to achieve atomic-resolution with even 15 keV electrons. The recent development of monochromators with ultra-high energy resolution has also opened up new opportunities to explore local spectroscopic properties of these materials at the nanometer-scale or even atomic-scale. This symposium will bring together experts working on electron microscopy studies of carbon-based nanomaterials and 2D materials, with focuses on low-voltage imaging, high resolution spectroscopy, in-situ microscopy and new microscopy techniques suitable for the studies of beam-sensitive materials.

Microscopy has always played a key role in both measuring atomic scale detail and connecting it to how they matter for hard or soft science, pure or technology. This symposium will cover different aspects of these two, for instance:

[ Topic of Interest ]

Understanding the nanostructure of polymers and other soft matter is essential for the development of next-generation functional materials ranging from energy-capture to optoelectronics to biomaterials with countless applications across the physical and life sciences. Electron microscopy has unique potential to probe molecular-level organization, nanostructures, phase separation and interfaces in these soft materials and give insight into their formation, properties and function. Recently, there have been technological advances such as new holders, electron phase plates, and sensitive and high-speed direct electron detection cameras. These have driven great progress in the areas of in-situ and spatiotemporal TEM imaging, cryogenic-TEM, 3D reconstruction by tomography, 4D STEM and ultralow dose imaging with enhanced contrast. Coupled to these developments, new computational and algorithmic approaches have given rise to new opportunities for retrieving quantitative and atomic-level information about the pristine structure of electron-dose sensitive and challenging materials. This symposium will bring together leaders in the development of these new electron microscopy approaches (spatiotemporal, in-situ and cryo-TEM imaging, 4D STEM, tomography) to discuss recent progress and outstanding challenges for a broad range of important soft material research areas such as: polymers, liquid crystals, colloids, gels, ionic liquids, metal-organic frameworks, biological materials, hybrid-materials etc. It will be an opportunity for comprehensive understanding and discussion of scientific achievements and related cutting-edge technologies toward the high-resolution imaging of soft materials at the nanoscale and atomic-level.

Phase transformation is closely related to materials' various properties, including mechanical and corrosion properties. The diffusional, displacive, and deformation-induced phase transformation of the matrix and precipitate controls the mechanical properties. On the other hand, oxidation and passivation behaviors, controlling corrosion properties, are dynamic phase transformation phenomena on the metallic surface under gaseous or liquid environments. Current advances in microscopic technique enable us to understand the veiled phenomena related to these phase transformations. This symposium will open for the mutual communication of cutting-edge research on phase transformation and corrosion behavior using microscopic techniques.

Many of the important properties of functional materials used for energy conversion and energy storage are controlled by the details of their microscopic structure from atomic arrangements and bonding to morphology and phase stability at nanoscale up to macroscale. Such materials include novel electrodes and electrolytes in batteries and supercapacitors; materials for photovoltaics like perovskites, organic blends and inorganic semiconductors; materials for catalysis, for example for water splitting, which may comprise metal alloy nanoparticles, complex oxides and metal-organic frameworks, as well as electrodes and membranes for fuel cells. Common challenges across studying these materials are 1) that they often contain light elements leading to low contrast, are 2) generally sensitive to irradiation damage in the microscope, 3) may degrade on exposure to air and 4) are often difficult to study in-situ/in-operando. This session will explore the latest results studying energy materials using imaging, diffraction and spectroscopic methods.

Analytical Science
Electron Optics or, more general speaking, charged particle Optics is the core technology required for any type of instruments of which charged particles are used to image, analyze, modify or measure any property of the object one is interested on. Hence, any development for an improvement of performance of such an instrument either for imaging or analytical methods or for modifications of the object needs theoretical and experimental expertise of charged particle systems. In addition, the dimension of such charged particle optics devices can be from µm range up to m range but the physics behind is always the same. This symposium will be dedicated to developments of charged particle instruments for all sort of applications from investigations of surfaces to basic research at the atomic level as well as from the measurement of various properties to the visualization of chemical processes. However, the instrumentation in general is the main topic and not purely applications of an instrument.

This session focuses on a wide range of techniques that collect more than one data point per image pixel on the (predominantly) elastic scattering within the sample. While holographic techniques (off-axis holography, focal series reconstruction, differential phase contrast, etc.) produce already two data points (a complex number) per image pixel, diffraction mapping (4DSTEM, SNBED, scanning PED; etc ..) produces even more data and may be used to identify the local crystal phase and orientation, strain, etc. or be reduced by various numerical procedures to a holographic signal again. Abstracts focusing on any of the above techniques, techniques related to those, but also electron diffraction carried out for a single location on the sample, are welcome to be submitted to this session.

• Holographic EM techniques (e.g. off-axis holography, inline holography)
• Holographic STEM techniques (e.g. DPC, 4DSTEM), Quantitative electron diffraction (e.g. phase/orientation identification, retrieval of structure factors, etc)

Scanning electron microscopy (SEM) is the most common and established electron microscopy technique. Reasons for this are its enormous versatility of observation techniques enabling the study of a vast amount of materials and material states, its high degree of automation, and its relative ease of operation. SEM based techniques span observation of materials from soft biological matter all the way to metals, semiconductors, minerals and ceramics. They cover high resolution imaging with secondary electrons, spectroscopic methods like x-ray spectroscopy for elemental composition measurement, Raman spectroscopy for strain measurements, cathodoluminescence for opto-electronic property measurements and diffraction techniques like electron backscatter diffraction (EBSD) techniques and electron channelling contrast imaging (ECCI) for the investigation of crystalline matter.
The focussed ion beam (FIB) scanning microscopes are usually built in combination with SEMs although they display an independent class of instrumentation. Mostly FIBs are used for target preparation of samples for transmission electron microscopy and atom probe tomography where one profits of simultaneous observation and analysis with the joint SEM. Nevertheless, they are also used for micromachining of samples for SEMs (e.g. for local mechanical testing) or for exposing features for further investigation with SEM e.g. by serial sectioning to perform 3D materials analysis. The combination with mass spectroscopy also allows high resolution elemental analysis. Lately the combination of FIB and SEM with laser beams enables the controlled removal of large amounts of material which offers further powerful preparation and investigation means.
Although SEM and FIB are very well established techniques, they are still strongly developing both in equipment, techniques and applications. The optical system of SEMs allows reaching ever increasing resolutions at lower voltages, femto-second laser sources are added for precise material machining, detectors develop towards higher sensitivity and detection speed and can be placed more flexible in the microscope chamber, in-situ testing equipment has become more versatile and the analysis techniques in spectroscopy and crystallography, for example, are becoming ever more sophisticated. 3D materials analysis techniques by serial sectioning, e.g. with EBSD, EDS and BSE are opening new insights into hard and soft matter, and new data analysis algorithms, including handling of big serial sectioning data sets and machine learning for feature recognition make the SEM and FIB methods even more powerful.
s related to microscopy and its application in the arts from two perspectives. The first perspective involves understanding artwork through the use of microscopic technology. The composition and material properties of layers in works of art are crucial factors in their conservation and valuation, and microscopic and spectroscopic techniques have contributed significantly to uncovering hidden stories and preserving world-class masterpieces. These techniques include the analysis, preservation, and restoration of artworks and artifacts. The second perspective is to provide a comprehensive overview of the intersection between Art and Science, which explores the creative inspiration derived from images obtained through microscopy, as well as the creation of art through microscopic techniques.

This includes the development or advanced use of monochromatic EELS, cathodoluminescence or electron energy gain spectroscopy in the infrared/vis/UV range, phase shaping or polarisation techniques, event-based techniques and electron/photon coincidence. Applications to materials whose properties are determined by low-energy excitations (phonons, excitons, polaritons, plasmons...) are encouraged.

Recently, in the field of additive manufacturing (AM), many researchers have investigated the complex correlations between processing, microstructure and mechanical properties of various metallic alloys. Since additively manufactured materials have very different microstructures from those obtained in conventional manufacturing processes, it is necessary to approach research related to analysis from a different perspective. In particular, different analysis techniques are required for each length scale (Å to cm) corresponding to the characteristics of the microstructure. This symposium aims to introduce the results of research analyzing the development of microstructure in materials produced by various additive manufacturing routes and to create an opportunity to foster technical discussions regarding both microstructure and characterization techniques.

This symposium provides a forum for the presentation of fundamental research advances and technological progress in the understanding, processing, and applications of aperiodic crystals, including quasicrystals, metallic glasses, and related materials. Aperiodic crystals are of technological importance for their performance in extreme environments because of their atomic structure, and crystal chemistry. These novel aperiodic crystals possess a range of advantageous mechanical and functional properties, but a complete understanding of how microstructure relates to properties is still lacking. The study of aperiodic crystals offers exciting opportunities to investigate how microstructures respond to the environment and how this eventually affects the mechanical and physical properties. This symposium provides an opportunity for scientists and engineers to present and discuss the latest theoretical and applied research related to the atomic structure, processing, and properties of aperiodic crystals.
