Beyond conventional chemical mapping: prospects and challenges of orbital mapping

Aberration correctors, electron energy-loss spectroscopy (EELS) and energy-dispersive X-ray spectroscopy (EDX) are nowadays indispensable tools for obtaining atomic-scale information of chemical composition and bonding in materials. Not only can material phases be identified, but important effects such as interdiffusion between phases, or charge ordering, to name but a few, can be studied. In the past decade, in EELS low energy losses were intensively used to identify surface plasmons in nanomaterials, even in a tomographic approach. This was made possible by the implementation of electron monochromators into the electron gun. Recent technological advances have opened the energy-loss window into the sub-10 meV regime where a range of new phenomena can now be studied. These include phonons, low-energy plasmons, and possibly many more low-energy excitations in materials. The wealth of information generates new grand challenges in understanding and modelling the underlying fundamentals of signal generation and intelligent processing of large data sets. Contributions are invited on hardware and technique developments, theory and simulation, data processing as well as applications covering both physical and biological sciences.

MS 1: Energy-related materials and catalysts

The session is focused on generating insights into the function of materials for energy storage, energy conversion and catalysis. Topics can be – but are not restricted to - charge transport, dynamics at interfaces (electrolyte/electrode or gas-phase/catalyst surface), cycling behavior and aging/deactivation. We are very interested in contributions that attempt to capture the relevant functional state of energy materials and catalysts, i.e., studies that reach beyond imaging of isolated systems in vacuum or investigations that employ an embedded multi-scale (in space and time) approach that allows to link between atomistic and collective dynamics. We also call for contributions regarding efficient detection of various generated signals, correlative application of analytical methods, as well as utilizing and developing quantitative data-analysis and machine learning. Studies on the impact of the electron beam for (in-situ) investigation of materials for energy-related or catalysis applications are also highly welcome.

Design-optimized conductive 2D conjugated metal-organic frameworks allowing sub-Ångstrom resolution HRTEM imaging

This symposium is hosted by the DGE Young Microscopists working group (yDGE) and will cover topics especially interesting for young researchers. For this, we invited experts who will give insights on publication writing and career planning.
In addition, we want to offer students the opportunity to give a short talk on their work in front of their young colleagues, to gain presentation experience in a casual atmosphere and enhance the scientific exchange.
The newly founded working group DGE Young Microscopists will briefly introduce their activities and possibilities to join.
Our goal is a lively, relaxed exchange between students and early-career postdocs to connect to like-minded colleagues. For this, the symposium will be followed by a social event nearby the conference's venue.

Seeing into organic 2D materials: defects, dynamics, and resolution

This session focuses on the development and application of advanced imaging, diffraction and spectroscopy to provide new insight into the structural, compositional and functional properties of low-dimensional and quantum materials. A specific focus will be placed on methods for imaging individual defects, enhancing the contrast of light atoms, preparing and cleaning ultra-thin samples, developing automated workflows for low dose imaging of beam sensitive materials and linking electron microscopy with complementary characterisation techniques. Other topics of interest include in situ experiments carried out at cryogenic or elevated temperature, as well as in the presence of external stimuli such as applied voltage, field, gases or light.
