Stability of a Bifunctional Cu-Based Core@Zeolite Shell Catalyst for Dimethyl Ether Synthesis Under Redox Conditions Studied by Environmental Transmission Electron Microscopy and In Situ X-Ray Ptychography
ddc:570
When using bifunctional core@shell catalysts, the stability of both the shell and core–shell interface is crucial for catalytic applications. In the present study, we elucidate the stability of a CuO/ZnO/Al$_2$O$_3$@ZSM-5 core@shell material, used for one-stage synthesis of dimethyl ether from synthesis gas. [...]

Structure and Composition of Isolated Core-Shell (In, Ga) N/GaN Rods Based on Nanofocus X-Ray Diffraction and Scanning Transmission Electron Microscopy
ddc:530
Nanofocus x-ray diffraction is used to investigate the structure and local strain field of an isolated (In,Ga)N/GaN core-shell microrod. Because the high spatial resolution of the x-ray beam is only 80×90  nm$^2$, we are able to investigate several distinct volumes on one individual side facet. [...]

Focusing hard x rays beyond the critical angle of total reflection by adiabatically focusing lenses
ddc:530
In response to the conjecture that the numerical aperture of x-ray optics is fundamentally limited by the critical angle of total reflection [Bergemann et al., Phys. Rev. [...]

Perfect X-ray focusing via fitting corrective glasses to aberrated optics
ddc:500
Due to their short wavelength, X-rays can in principle be focused down to a few nanometres and below. At the same time, it is this short wavelength that puts stringent requirements on X-ray optics and their metrology [...]

Tracking the density evolution in counter-propagating shock waves using imaging X-ray scattering
ddc:530
We present results from time-resolved X-ray imaging and inelastic scattering on collective excitations. These data are then employed to infer the mass density evolution within laser-driven shock waves. [...]

Beamstop-Based Low-Background Ptychography to Image Weakly Scattering Objects
ddc:570
In recent years, X-ray ptychography has been established as a valuable tool for high-resolution imaging. Nevertheless, the spatial resolution and sensitivity in coherent diffraction imaging are limited by the signal that is detected over noise and over background scattering. [...]

ddc:620
Due to the weak interaction of X-rays with matter and their small wavelength on the atomic scale, stringent requirements are put on X-ray optics manufacturing and metrology. As a result, these optics often suffer from aberrations. [...]
