Papers

We are proud to announce two paper contributions to the 15th International Symposium on Superalloys, which took place from September 8th-12th, 2024, in Seven Springs, Pennsylvania (USA). Both contributions enhance our understanding of stacking faults, a critical aspect of high-temperature deformatio...

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 scientists have now demonstrated that the much more widespread and affordable scanning electron microscope (SEM) can be equall...

In collaboration with colleagues from the Department of Data Science, IMN 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 of the ...

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, 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 new tool ...

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 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 recently published a strategy to tackle and overcome the inherent compromise between accessible volume and spatial resolution in nanotomography. The article “Expanding accessible 3D sample size in lab-based X-ray nanotomography wi...

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 and the groups of P...

Our nanowire experts Dr. Lilian Vogl, Dr. Peter Schweizer (now both at EMPA, Thun Switzerland), and Peter Denninger from the Institute of Micro- and Nanostructure Research headed by Prof. Spiecker recently published their work about gold nanowires provided by Gunther Richter from the Max Planck Inst...
