Nottingham University, UK
September 2014 - Researchers from University of Nottingham have extended the lifetime of organic molecules under the electron beam via isotope substitution of Protium by Deuterium. Supporting this work, researchers from the University of Ulm have used aberration-corrected high-resolution transmission electron microscopy (AC-HRTEM) at 80 kV to quantify the critical dose for the decomposition of coronene encapsulated in SWNT depending on the hydrogene isotope.

University of Birmingham, UK
August 2013 - Palmer et al. from University of Birmingham, UK comment the paper by Angelova et al. 2013 about self-assembled monolayers, electron-beam writing, and carbon nanomembranes in the same issue of ACS Nano. They describe on the example of this paper how "nanoscience translates into technology" and reflect on progress in this field in which scientists "are pulling together complementary stands from a quarter century research to develop novel, hybrid processing schemes".

University of Bielefeld, Germany
August 2013 - Researchers from University of Bielefeld have investigated transformation from Self-Assembled Monolayers (SAMs) of numerous aromatic molecules via electron-beam irradiation to Carbon Nanomembranes (CNMs). Supporting this work, researchers from the University of Ulm have used aberration-corrected high-resolution transmission electron microscopy (AC-HRTEM) at 80 kV to reveal the atomic structure of CNMs after conversion into graphene.

Northwestern University, USA
July 2013 - Laurence D. Marks from Northwestern University, USA comments CEOS' article about "Thermal Magnetic Field Noise and Transmission Electron Microscopy". He explains "What are the Resolution Limits in Electron Microscopes" and discusses the new "Unexpected barrier to better resolution in electron microscopes" in the context of the recent developments and the future of the Electron Microscope in Materials Science.

CEOS - Corrected Electron Optical Systems company, Germany
July 2013 – Uhlemann and Co-authors from CEOS company build the Cc/Cs-corrector for the SALVE project. Now they have identified that magnetic field noise from thermally driven currents in the conductive parts of the instrument is the root cause for a hitherto unknown phenomenon that limits resolution in Electron Microscopes.

University of Alberta, Canada
October 2012 - Raymond F. Egerton from the University of Alberta, Canada is visiting professor at Ulm University, Germany. He opened a lecture course for graduated students on "Introduction into analytical electron microscopy" with the 2-weeks course on "Electron Energy Loss Spectroscopy". He also gave two SALVE-Seminar talks in the field of radiation damage. Egerton discussed in his paper the "Mechanisms of Radiation Damage in Beam-Sensitive Specimens, for TEM Accelerating Voltages Between 10 and 300 kV" in Microscopy Research and Technique.

LBNL - Lawrence Berkeley National Laboratory, USA
October 2012 - TEAM project, USA reports on the decrease of the accelerating voltage of the aberration-corrected TEAM0.5 TEM 80-300 down to 20 kV.
-
CEOS - Corrected Electron Optical Systems company, Germany
July 2012 - CEOS, founded in 1996 by Maximilian Haider and Joachim Zach, is now concentrating on incorporation of a new electron optical component in the SALVE II microscope. The development includes correction for the spherical, chromatic, and coma-type aberrations. The CEOS company has meanwhile become the world leading manufacturer of correctors for electron microscopes. In particular, the company CEOS has built the Cc/Cs-corrector for the 0.5-Å TEAM microscope - a microscope that breaks the limits in materials science. In this successful tradition, SALVE scientists come now a step closer to the dream of the first fully corrected low-kv-tunable high-resolution electron microscope.

ZEISS Microscopy, Germany
July 2010 - First measurements with the ZEISS LIBRA® 200 TEM operated at 20 keV. With aberration correction at lower accelerating voltages, a new trend in transmission electron microscopy was opened, in order to fulfil the growing demand of imaging electron beam-sensitive materials at their atomic level. Until now, resolution performance has been unknown at accelerating voltages between 20-80 keV.
