Electron tomography reveals the inner structure of magic colloidal clusters
Self-assembly processes play an important role in nature and often result in complex structures, e.g. in chlorophyll or in living organisms. Compact clusters of elemental particles can be shown to be of practical relevance, and are found in atomic nuclei, nanoparticles or viruses. Self-assembly of magic number colloidal clusters takes place in several steps. […]

Plasticity at the fingertips
In the 1940s, scientists first explained how Materials can deform plastically by atomic-scale line defects called dislocations. These defects can be understood as tiny carpet folds that can move one part of a material relative to the other without spending a lot of energy. Many technical applications are based on that fundamental process, such as […]

New tomography technique developed at CENEM highlighted on the cover of Small Methods
In the research paper Thomas Przybilla, Benjamin Apeleo Zubiri and co-workers present a versatile approach that provides a general routine for advanced 3D characterization of micro- and nanoparticles. The method which was developed at IMN and CENEM involves the transfer of individual particles onto tailored tips using a scanning electron microscope equipped with a micromanipulator. […]

In situ microscopy directly reveals dislocation formation in MAX phase
Researchers at CENEM have recently reported the direct observation of nucleation and propagation of basal plane dislocations in Nb2AlC, a member of MAX phases, using nanomechanical testing inside a transmission electron microscope. MAX Phases (with M an early transition metal, A an A group element and X being either nitrogen or carbon) constitute an interesting […]

Mystery of butterfly research resolved
High-resolution X-ray tomography reveals how butterflies form their iridescent wing scales. It has only been one year since the material scientists around Prof. Erdmann Spiecker from the Center for Nanoanalysis and Electron Microscopy (CENEM) at the FAU Erlangen-Nuremberg had been granted funding for one of the World’s best X-ray microscopes, and they could already contribute […]
