Subnanometric Platinum–Germanium Clusters for Efficient Propane Dehydrogenation Catalysis

Small, EarlyView.
Pt─Ge alloy clusters are regioselectively encapsulated within the sinusoidal channels of pure silica MFI zeolite (PtGe@MFI). The developed Pt─Ge alloy clusters exhibit exceptional performance with 36‐fold higher activity than the most stable catalyst ever reported and twice its stability, and with comparable activity to and 21‐fold higher stability ...

Aligning Real‐Time Recurrence Computational Fluid Dynamics Simulations with Plant Data for the Ruhrstahl–Heraeus Degassing Process of Steel

steel research international, EarlyView.
Uncertainties exist in computational fluid dynamics (CFD) modeling of complex metallurgical processes, even when partly validated by laboratory experiments. rCFD enables computationally efficient prediction of long‐term RH degassing and can be adapted to vary flow conditions.

Metal‐Free Electrophilic Borylative Cyclizations of Alkynes

The Chemical Record, EarlyView.
Metal‐free borylative cyclizations based on electrophilic alkyne activation by boron Lewis acids provide efficient access to borylated hetero‐ and carbocycles. Early studies using B(C6F5)3 displayed limited scope and application, whereas recent ClBcat‐ and BCl3‐based methods enable mild CB and CC/CX bond formation for the synthesis of cycles ...

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety

High Voltage, EarlyView.
ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...

A new branch of mammalian vitamin B6 metabolism: AKR1C‐mediated conversion of pyridoxal to pyridoxine and 4‐pyridoxolactone

The FEBS Journal, EarlyView.
Pyridoxal 5′‐phosphate (PLP) homeostasis relies on salvage enzymes, yet key metabolic branches remain undefined. We identify AKR1C isozymes as previously undescribed contributors that convert pyridoxal into pyridoxine or 4‐pyridoxolactone through reductase and dehydrogenase activities.
