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...

We are proud to announce that our new transmission electron microscope (TEM) Thermo Fisher Scientific (TFS) Spectra 200 is now open for user access within the user facility of CENEM. The state-of-the-art TFS Spectra 200 provides high-resolution imaging (probe-corrector for STEM imaging) down to the...

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...

If you have a request for the CENEM electron microscopy and X-ray imaging facilities regarding a collaborative work or a service measurement or if you would like to become an operator at an electron microscope and need device instructions, please use our new online request form. To facilitate future...

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...

The formidable years ever since the pandemic has greatly affected the extent of academic exchange and driven us towards a new culture of online discussions. Despite many virtual events successfully held, few of them served as a platform for early career researchers and brought a broader community be...

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...

The article “Effect of size and shape on the elastic modulus of metal nanowires” by Lilian Vogl, Peter Schweizer, Gunther Richter and Erdmann Spiecker has recently been published in MRS Advances. Congratulations, Lili and Peter! The CENEM/IMN researchers make use of the resonance vibration of metal ...

The article “Unraveling Structural Details in Ga-Pd SCALMS Systems Using Correlative Nano-CT, 360° Electron Tomography and Analytical TEM” by Janis Wirth, Silvan Englisch, Dominik Drobek, Benjamin Apeleo Zubiri, Mingjian Wu, Nicola Taccardi, Narayanan Raman, Peter Wasserscheid and Erdmann Spiecker h...
