A new set of generalised oscillator strengths for EELS quantification by UMünster and CEOS * 23.08.2023
Tabulated generalised oscillator strengths are necessary for the quantification of most core-loss edges in EELS. The collaboration between CEOS GmbH and L. Segger and H. Kohl from the University of Münster has recently produced the first publicly available GOS database, filling a decade old void. The new data cover more edges and have better sampling then previous one, and are also available to everyone, under a permissive CC-BY license. More information (as well as the data and source code) can be found on Zenodo.
The new data is already employed in the latest version of CEOS Panta Rhei, and will be supported in HyperSpy 2 thanks to our contributions, finally making available the tools for a transparent processing of EELS data to the TEM community and to the public.

First applications of our CEFID combined with a Dectris Hybrid-Pixel detector have now been published in Micron in the paper Applications of a novel electron energy filter combined with a hybrid-pixel direct electron detector for the analysis of functional oxides by STEM/EELS and energy-filtered imaging. by a group at the EMPA.
The Dectris ELA hybrid-pixel detector is now available as an add-on for our CEFID imaging energy filter. * 13.03.2022
We are excited to announce that CEOS is now offering a DECTRIS ELA hybrid-pixel electron detector integrated in their energy filtering and imaging device CEFID. For more details see Dectris.
CEFID Ultra-Fast TEM * 23.12.2022
Researchers from University of Göttingen, Germany, use our imaging energy filter CEFID at a JEOL 2100F Ultra-Fast TEM to study light/electron interaction in integrated photonics chips by EFTEM with 0.8eV energy-selection slit and large field of view. Our spectrometer is equipped with a TVIPS XF416 CMOS camera as well as a ASI Cheetah TimePix detector. For more details see Nature publication.
Distinguished Scientist Award 2021

In sight: A paradigm shift in materials characterization * 04.03.2021
Researchers from Lehigh University (USA) have joint forces with JEOL (Japan) and CEOS GmbH (Germany) to improve electron energy-loss spectroscopy for very high core-loss energies currently only well accessible by synchrotron-based X-ray absorption spectrometry.
CEOS technology helps to improve resolution in Cryo-Electron Microscopy *04.06.2020
Nature reports about two projects which have demonstrated improved resolution for single particles analysis:
- Yip et al. from Max-Planck Institute for Bio-Physical Chemstry, Göttingen, Germany for the first time use a CEOS Aplantic Cs-corrector BCOR [1] for Cryo-TEM.
- Nakane et al. from Medical Research Council Laboratory of Molecular Biology in Cambridge, UK use an energy filter for zero-loss imaging based on CEOS know-how [2].

Janis Köster receives Harald Rose Prize 2019 *5.08.2019
As part of the ceremony marking the 52nd anniversary of the University of Ulm, Janis Köster received the Harald Rose Prize 2019. The university wrote on its website: "The 3000 Euro Harald Rose Prize went to Janis Köster. The young scientist studied defects in a two-dimensional material using high-resolution electron microscopy and carried out accompanying calculations. His Master's thesis, which he performed in the Electron Microscopy Group of Materials Science, lead directly to several publications. The prize is named after a pioneer in electron microscopy, Professor Harald Rose, who holds a senior professorship at the University of Ulm." One of these publications can be viewed under Electron-Beam-Driven Structure Evolution of Single-Layer MoTe2 for Quantum Devices . You can read a full press release by the SALVE team there.
Member of the Class 2019 Fellows of the Microscopy Society of America *21.03.2019
