, 2021 Gamma-ray bursts (GRBs) are the most energetic explosions in the Universe. They are collimated, ultra-relativistic outflows which are powered by a central engine. When the ejected material starts to interact with the surrounding medium, shocks are formed where particles can be accelerated to emit synchrotron emission.

Small Methods, EarlyView.Enhanced OER by surface reconstruction: The dopant promotes surface reconstruction and surface oxygen vacancies, which enhance electrochemical activity, charge transfer, and stability, resulting in improved water and urea electrolysis. Abstract Constructing robust electrocatalysts and shedding light on the processes of surface reconstruction is crucial

steel research international, EarlyView.This study uses in situ synchrotron X‐ray diffraction at the German Electron Synchrotron to analyze low‐pressure carburizing (LPC) in steels. The findings reveal surface carbon saturation and carbide formation kinetics, and phase‐specific stress development during quenching. The results show carbide kinetics depend on steel grade and size, while stress

Small Structures, EarlyView.Flexoelectric polarization is harnessed to dynamically enhance phosphatase‐mimicking catalysis in Gd‐based nanoflowers, enabling ultrasound‐responsive and efficient biophosphate ester hydrolysis through strain‐induced electronic modulation. Phosphatase‐mimicking nanozymes provide highly stable enzyme‐like activity but remain limited by their static ...
