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...
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 CENEM 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 Planc...
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 a joint effort across 4 GRK subprojects involving 10 GRK members, CENEM’s strength of combining different (scattering) probes revealed fascinating structural, chemical as well as mechanical properties of supersaturated and highly faceted Ni-Au nanoparticles equilibrated by solid-state dewetting o...
Our CENEM & GRK work entitled “Hydrogenated Anatase TiO2 Single Crystals: Defects Formation and Structural Changes as Microscopic Origin for Co-Catalyst Free Photocatalytic H2 Evolution Activity” was just published in the Journal of Materials Chemistry A (DOI: 10.1039/D1TA04809K).
The photocata...
