The ER-C is a centre of excellence in advanced transmission electron microscopy and spectroscopy for addressing topical problems in solid state physics and chemistry, materials science, soft matter and biology.



The ER-C operates a user facility that provides access to state-of-the-art instruments, methods and expertise to universities, research institutions and industry. It is governed jointly by FZJ and RWTH Aachen.

Vincenzo Grillo, Alberto Roncaglia, Paulo Rosi and the Q-SORT project.


New techniques and instrumentation are developed by the ER-C’s scientific and technical staff in collaboration with academic and commercial partners, as well as with the instrumentation institutes in Forschungszentrum Jülich.



The ER-C is a key part of the European landscape of infrastructures for the characterization of materials using advanced techniques and instrumentation.

Cryo-Electron Microscopy Makes Structure of Important Membrane-deforming Proteins Visible

Viruses multiply in the human body by hijacking the functions of cells and using them for their own purposes. Ebola, HIV and other viruses use, among other things, the so-called ESCRT-III complex for this purpose.


PICO 2021

The Sixth Conference on Frontiers of Aberration Corrected Electron Microscopy, is scheduled to take place in spring 2021. The conference will again address recent advances in methods and applications for the study of solids in condensed matter research and the life sciences by the application of advanced electron microscopy techniques.

ER-C 2.0

The large-scale infrastructure project ER-C 2.0 was ear-marked to be part of Germany’s National Roadmap. It was selected as a priority in terms of both strategy and research policy.


How the "PICO" Microscope Works

A unique transmission electron microscope with a resolution of 50 picometres has been available for use by researchers at the ER-C since February 2012.  You can see how the “PICO” (Advanced Picometre Resolution Project) works in this video.



JuStruct is an integrated user platform for the investigation of atomic structures of medically and neurobiologically relevant proteins using NMR spectroscopy, X-ray crystallography, computer-aided structural biology, neutron scattering and spectroscopy, and cryo-electron microscopy.



ESTEEM3 – Enabling Science and Technology through European Electron Microscopy – is an EU funded project for electron microscopy, which aims at providing access to leading European state-of-the-art electron microscopy research infrastructures.



This European Research Council Synergy project aims at studying three-dimensional magnetic solitons with high temporal and spatial resolution, bringing together experts on magnetic imaging, magnetic manipulation, theory and device applications.
