Monolithic integration of SiC diode detectors into scanning X‐ray microscopy optical elements for in situ beam diagnostics

Journal of Synchrotron Radiation, EarlyView.
Silicon carbide detectors are monolithically integrated into order‐sorting apertures and center stops for in situ soft X‐ray beam diagnostics in STXM. Functionalized components enable simultaneous monitoring of incident beam intensity and the transverse position at sample‐relevant locations without degrading optical performance.Reliable monitoring of ...

Pressure‐dependent coupling between arterial pressure and intercostal muscle blood‐flow index during acute hypotension in humans

Experimental Physiology, EarlyView.
Abstract Regulation of respiratory muscle blood flow during acute systemic hypotension remains poorly understood in humans because continuous assessment of microvascular perfusion during rapid haemodynamic transients has been technically challenging. Using diffuse correlation spectroscopy, we investigated second‐by‐second coupling between mean arterial

Review of Amorphous Gallium Oxide: From Material Synthesis to Device Applications

physica status solidi (a), Volume 223, Issue 15, 5 August 2026.
Amorphous gallium oxide (a‐Ga2O3) is reviewed as a promising ultra‐wide‐bandgap material for solar‐blind UV photodetectors. The influence of structural disorder, defect states, and trap‐assisted transport on optical and electronic performance is examined.

Coupled Operando Mössbauer‐Raman Spectroscopic Analysis of Iron Molybdate Catalysts During Oxidative Dehydrogenation

ChemCatChem, Volume 18, Issue 15, 14 August 2026.
We demonstrate the potential of a coupled SMS‐Raman setup for the ODH of EtOH over a Fe2(MoO4)3 + MoO3 catalyst during reductive conditions. Coupling both methods allows to distinguish (sub)surface and bulk properties of the material during catalysis, that can be correlated with activity and selectivity data from mass spectrometry.
