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...

Taming radiation effects during in situ studies in liquid phases is a major challenge for investigations with ionizing radiation, such as electrons or X-rays. In a recent work published in Advanced Science, researchers of FAU (IMN, CENEM, LEB, ICSP, LKO), Helmholtz-Institute Erlangen-Nürnberg for Re...

Crystals are not necessarily hard and resistant but also occur in soft matter when weakly bound molecules arrange in a regular order. Such organic crystals are widespread in pharmaceuticals products, but also occur as tiny nanocrystals in the active layer of organic solar cells. Here, the organic na...

Emerging functional materials for applications in photonics, plasmonics, and mechanics can be created by assembling smaller particles into defined structures. Among various assembly strategies, spherical confinement (e.g. in drying emulsion droplets) to guide the self-assembly process is gaining inc...

In situ TEM investigations in environmental conditions are a powerful approach to analyze materials for catalysis, especially if you utilize dedicated MEMS heating systems to operate at elevated temperatures. However, how can we be certain that the heating devices achieve the required temperature at...
