Understanding X-ray reflection as a probe of accreting black holes
The reflection of the X-rays emitted from a corona of energetic particles surrounding an accreting black hole from the accretion disc is investigated in the context of probing the structure of the central regions as well as the physical processes that power some of the brightest objects seen in the …

The equilibrium shape of NaCl single crystal studied by x-ray reflection on its surfaces
… of NaCl single crystals has been studied by x-ray reflectivity measurements at high symmetric surfaces. The equilibrium shape of a crystal is related to the properties of its surfaces through its surface free energy by means of the Wulff construction. Glancing angle x-ray reflectivity is used …

Influence of High Temperature Creep upon the Structure of ß-NiAl and ß-NiAl(Fe) Single Crystals
… is established following the classic line of X-ray structure analysis, namely controlling the chemical composition with the electron probe microanalysis, determining the unit cell contents from the combined lattice parameter and mass density measurements, and refining the structure parameters …

High precision x-ray spectroscopy on highly charged argon ions
… two beams of visible light reflected on the x-ray crystal to mark the x-ray reflection position. The need for collimating entrance slits causing unacceptable x-ray flux losses is thereby avoided. Relative uncertainties of better than $\Delta \lambda / \lambda < 10^{-5}$ were achieved in the …

Unveiling fundamental physics with high-resolution X-ray spectroscopy of Active Galactic Nuclei.
… flow onto SMBHs in AGNs as revealed by X-ray observations of AGNs. This is followed with a discussion on the use of X-ray reflection spectroscopy as a probe of the spin of moderately accreting SMBHs, and the use of spin diagnostics to probe the growth of SMBHs over cosmic timescales. …

Directed lithium transport in high capacity lithium-ion battery electrodes
… of lithium-ion batteries utilizing x-ray microscopy, nuclear magnetic resonance, transmission electron microscopy, and scanning probe microscopy have recently been utilized to understand fundamental phenomena occurring during (dis)charge cycling. X-ray Reflection Interface Microscopy …

Adsorption of alkyl amides: monolayer structures and mixing behaviour
… using a combination of synchrotron X-ray and neutron diffraction and Differential Scanning Calorimetry (DSC). Exceptionally stable solid layers have been observed at temperatures well above the bulk melting point, at both high multilayer coverages and, very unusually, at sub-monolayer …
