USER TALK: COMPLEXITY IN STRUCTURES DRIVEN BY ION DYNAMICS

By

Solid ion conductors are fascinating materials for energy conversion and storage applications. Due to their intrinsic properties and especially their high ion mobility in the lattice they are often characterized by complex crystal structures, polymorphism and the loss symmetry during structural phase transitions. This last aspect often causes twinning and demands the collection of precise data and the usage of group-subgroups relations to solve and understand their crystal structures. Beside the structural features of a selection of solid ion conductors discussed in this presentation also intriguing electronic property changes can occur that are closely related to the ion dynamics and structure changes upon heating or cooling of such materials. In this talk we present a series of copper and silver ion conductors that also show reasonable electronic conductivities which characterize them as mixed-conducting semiconductors. […]

THE STOE SPHERES – A NEW ANALYTICAL TOOL

By

STOE SPHERES, a new analytical tool for:
Visualization of direction-dependent populations
Easy assessment of coverage for desired direction-dependent scaling
Representation of direction-dependent deviations, changes and scale factors
Recognition of direction-dependent underscaling/overscaling
Better understanding of Spherical Harmonics
Identification of outliers
Join us for this presentation followed by a live-demonstration of the new features!

PUSHING THE LIMITS – STOE’S TWIN PORT METALJET SOLUTION

By

See how we designed for Karlsruhe Institute of Technology an X-ray diffraction system for both, single-crystal diffraction and powder diffraction powered by a dual port Excillum MetalJet source. With two exchangeable wavelengths usable for both end-stations, a unique service and alignment concept and the latest Dectris detector technique, this system tackles their most demanding applications.
