Instrumentation & Methodology Symposia

IM-01 - Advances in 3-dimensional image reconstruction

The session will cover the quantitative analysis of X-ray and electron based 3D microscopy data. Electron and X-ray 3D microscopy is widely used in material science and is an emerging field with great potential in bioimaging. With the possibility of imaging 3D structures at high spatial or temporal resolution both ex and in vivo allows structural quantification that has many applications in bioimaging. In situ 3D imaging within materials science and 3D imaging of the interface between biology and materials science often requires imaging at different length scales. The full potential of electron and X-ray 3D microscopy can only be utilized having automated analysis methods and subsequent modeling tools. This session will focus on recent developments within X-ray 3D microscopy for both laboratory and large-scale synchrotron facilities as well as applications of 3D imaging techniques by electron sources.

IM-02 - Innovative, modular and adaptable hardware: design, application and control 

Developments in electronics, manufacturing and modular components have lowered the barrier for microscopists to design, build and test their own innovative instrumentation. Advances in scripting, open control libraries (e.g. Python), have enabled users to control their instruments in more automated, accessible and flexible ways. In parallel, the drive towards inter-operable systems motivates the use of standardised ports, flanges and connectors. This session will explore innovations in low-cost, standardised, modular, and/or retrofitted and repurposed hardware, as well as novel methods of instrument control, acquisition or automation.

IM-03 - Phase-related methods

This session will cover new developments in phase-related imaging techniques across electron microscopy, x-ray imaging and allied techniques. With the proliferation of high-speed detectors, we are increasingly able to (i) make use of phase-structured illumination in the imaging process, and (ii) employ novel reconstruction algorithms to extract both the phase and the amplitude of the transmitted beam – revealing samples in increasingly complex detail. In this session, we look forwards to exploring the synergy of these two approaches. We seek submissions relating to phase retrieval methods (i.e. ptychography, (Lorentz) DPC-STEM, TIE), and submissions relating to phase shaping as employed in the imaging process (holographic and interferometric methods, vortex beams and other probe shapes).

IM-06 - Diffraction Techniques and Structural Analysis

In recent years structural analysis and nanoscale crystallography using electron diffraction and related techniques has been transformed through a series of major developments, including 3D ED/MicroED; the advent of remarkably sensitive, almost noise-free, cameras and detectors; the introduction of automated data collection and big data processing (e.g. machine learning); and the availability of dedicated software that enables robust and reliable structure determination from electron diffraction data. This has led to an explosion of interest in both the physical and life sciences in using these techniques to (i) solve crystal structures not amenable to more conventional x-ray diffraction and (ii) use the high spatial resolution of the electron microscope to reveal hitherto unseen micro- and nano-structure using 4D scanning methods, acquiring diffraction patterns at every real space probe position. This session highlights the progress made in this area using (scanning) transmission electron microscopy including 3D-ED/MicroED, 4D-STEM, SerialED, SED, SPED, PED, CBED, SCBED, HRTEM, time-resolved diffraction and ptychography, and in scanning electron microscopy (with techniques such as EBSD (2D and 3D), ECCI and TKD.

IM-07 - Dynamic studies using micro-nano labs 

Recent significant developments in electron microscopy, x-ray and scanning probe instrumentation with new in situ platforms and fast detectors enable in situ and operando experiments to be performed with high spatial-temporal resolution imaging, diffraction and spectroscopy with unprecedented detail. This provides us the opportunity to glimpse into the state and functionality of materials during synthesis, operation or degradation in a defined environment. In this symposium, we aim to highlight novel approaches to in situ microscopy enabled, e.g., by nanofabricated devices such as microchip systems and 2D material devices. Applications range from material processes studied under various stimuli including gas, temperature, liquid and mechanical, but also from the increasing use of these capabilities in life science and soft matter. We seek contributions illustrating equipment development and novel use of existing equipment both in TEM and SEM, x-ray platforms and scanning probe systems, that can provide new insight into the state of active materials including novel bio-, soft and hard materials, nanoparticles and catalysts.

IM-11 - Advances in Single Particle Analysis (SPA) and Cryo-Electron Tomography (cryo-ET) for Cryo-Electron Microscopy

Cryo-electron microscopy (cryo-EM) has become acrucial technique for analyzing molecular structures. Equally important is theapplication of these structures within their cellular context. This sessionfocuses on innovations in cryo-EM, including advancements in supportinginstrumentation and software analysis tools that are essential for achievinghigh-resolution results in both Single Particle Analysis (SPA) andcryo-electron tomography (cryo-ET) for studying cells in their nativeenvironment. The power of single particle techniques and cryo-ET has driven aresolution revolution in electron microscopy. However, the success of thesemethods relies heavily on sample preparation and quality. Poor sample quality,lack of reproducibility, and the high skill barrier in using supportingtechnologies often limit the potential of cryo-EM. Recent innovations incryo-EM include improved grid preparation, the development of new detectors,STEM imaging, and automated data screening and collection. Additionally, advancementsin methods for handling thick specimens using cryo-FIBSEM, cryo-FIB lift-out,and cryo-fluorescence microscopy have become invaluable tools for preparingsamples before cryo-ET analysis.

IM12 - Development of sample preparation methods, instrumentation, workflows, and data solutions for volume electron microscopy

Volume Electron Microscopy (VolumeEM) refers to a family of techniques that extend traditional 2D cross-section electron microscopy into the third dimension. Techniques within VolumeEM include serial block-face SEM, FIB-SEM, serial section SEM or TEM, grid-tape TEM, and multi-beam SEM. VolumeEM has the potential to revolutionize bio-imaging by providing high-resolution volumetric biological data within the 3D context of cells, tissues, organs, and organisms. Despite its promise, VolumeEM still faces several challenges. These include issues related to throughput, sample preparation that preserves ultrastructure and provides high contrast, producing high-quality 3D resolution images, ROI targeting, system stability during long acquisitions, data consistency, and handling and analyzing massive amounts of data.

This session will explore developments in sample preparation workflows, their strengths and challenges, instrumentation, data handling, and analysis for VolumeEM. Additionally, it will highlight applications of these techniques to uncover new insights in biology and related fields. Given that VolumeEM is often used in a correlative approach, the session will also discuss protocol compatibilities with other imaging modalities such as light microscopy and X-ray imaging.

IM-13 Correlative Microscopy Across the Scales 

Combining complementary imaging modalities can generate a highly informative, composite view of the sample and allows access to both structural and functional parameters across all relevant scales from the same sample. While the correlation of light with transmission electron microscopy (EM) is well established (generally referred to as CLEM), the frontiers of bioimaging are currently being pushed towards the integration of other modalities into correlative workflows, including both super-resolution and large-scale imaging techniques such as light sheet, X-ray or Volume EM to study intercellular relationships and put molecular information into its overall structural context.
