Constant enzymatic in situ production of H2O2 for an Unspecific Peroxygenase by an L‐amino acid oxidase

open access: yesAdvanced Synthesis &Catalysis, Accepted Article.
Unspecific Peroxygenases have been the subject of a lot of research in the recent past as they offer opportunities for green hydroxylation reactions using hydrogen peroxide (H2O2) as donor. A striking problem of UPOs is their low stability against their own co‐substrate H2O2.

Fluorescence Label‐Free Doxorubicin Sensor Using Polystyrene Sulfonate as a Synthetic Receptor in Whispering Gallery Mode Microresonators

open access: yesAdvanced Sensor Research, EarlyView.
The illustration showcases resonant optical microsensors for Doxorubicin (DXR) detection, using polystyrene sulfonate (PSS) as a synthetic receptor. PSS is deposited as a nanometer‐thick layer on fluorescent microparticles via layer‐by‐layer assembly. DXR‐PSS interaction is depicted, highlighting its effect on the sensor's resonant modes.

A High‐Performance Miniaturized Frequency Shift Detection System for QCM‐Based Gravimetric Sensing

open access: yesAdvanced Sensor Research, EarlyView.
A miniaturized frequency shift detection system based on a phase‐locked loop (PLL) circuit is proposed for simplifying QCM measurement, possessing excellent performance of high sensitivity, resolution, linearity, and accuracy compared with a commercial frequency analyzer.

Exploration of Half‐Cycle Length of Converging Circular Wavy Duct with Diverging‐Outlet: Turbulent Water Dynamics

open access: yesAdvanced Theory and Simulations, EarlyView.
Increasing half‐cycles intensifies turbulence due to enhanced vortex interactions and flow separation at the diverged‐outlets. Longer wavy ducts are shown to increase flow acceleration, resulting in greater output velocities and more turbulent‐kinetic‐energy production. Wave‐period plays a crucial role in determining turbulent intensity, with amplitude
