In collaboration with WW1 and Ruhr-Universität Bochum, the Institute of Micro and Nanostructure Research (IMN)/CENEM is proud to announce two paper contributions to the 15th International Symposium on Superalloys, taking place from September 8th-12th, 2024, in Seven Springs, Pennsylvania (USA). Both...
The classical way to study defects in crystalline materials is transmission electron microscopy (TEM). But do we always need this expensive and sophisticated instrument? IMN/CENEM scientists have now demonstrated that the much more widespread and affordable scanning electron microscope (SEM) can be ...
In collaboration with colleagues from the Department of Data Science, IMN/CENEM researchers developed a new compressed sensing method that uses mathematical optimization to improve the quality of 3D reconstructions in nanotomography of homogeneous materials. The work was performed in the framework o...
We are pleased to announce the recent publication of the paper "Structural evolution of GaOx- shell and intermetallic phases in Ga-Pt SCALMS" by S. Carl, J. Will, B. Apeleo Zubiri, E. Spiecker and colleagues in the Journal of Physical Chemistry Letters.
Propane dehydrogenation (PDH) has attracted...
In a milestone study, CENEM and IMN scientists have demonstrated a novel technique that uncovers the three-dimensional structures of nanomaterials, including those made of light elements that have eluded detection until now. This advance, which utilizes ptychographic electron tomography, showcases a...
The paper “Influence of Au alloying on solid state dewetting kinetics and texture evolution of Ag and Ni thin films” by Martin Dierner, Johannes Will, Michael Landes, Christian Volland, Robert Branscheid, Tobias Zech, Tobias Unruh and Erdmann Spiecker has just been published in the Journal of Surfac...
The "Olympics" microscopy, the 20th International Microscopy Congress (IMC20), took place last 10-15.September in Busan, South Korea, after being postponed by a year due to the pandemic. Over 3,000 people attended the grand event. We have met long-lost colleagues and friends during this congress and...
The paper "Reliable identification of the complex or superlattice nature of intrinsic and extrinsic stacking faults in the L12 phase by high-resolution imaging" by Nicolas Karpstein, Malte Lenz, Andreas Bezold, Mingjian Wu, Stefan Neumeier, and Erdmann Spiecker has just published in the Journal Acta...
Silvan Englisch and his colleagues from the nanotomography work group of the Institute of Micro and Nanostructure Research (IMN)/CENEM recently published a strategy to tackle and overcome the inherent compromise between accessible volume and spatial resolution in nanotomography. The article “Expandi...
We recently published the manuscript titled "3D analysis of equally X-ray attenuating mineralogical phases utilizing a correlative tomographic workflow across multiple length scales" in the journal Powder Technology demonstrating an interdisciplinary collaboration between the IMN/CENEM and the group...
