A Photoredox Radical‐Polar Crossover Reaction for the Preparation of Monoprotected Dicarbonyl Compounds

European Journal of Organic Chemistry, EarlyView.
An ATRA‐based, Ru‐photocatalyzed radical‐polar crossover reaction for the preparation of monoprotected dicarbonyl compounds is reported. This procedure is based on the capture of a cationic intermediate, arising from the radical step, with diverse nucleophiles.

Scour‐Conditioned Seismic Fragility Analysis of Monopile‐Supported Offshore Wind Turbines

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Monopile‐supported offshore wind turbines (MS‐OWTs) are increasingly deployed in seismic coastal regions, where they face compound risks from earthquake loading and seabed scour. While past studies have addressed these hazards separately, seismic fragility under evolving scour conditions remains insufficiently understood. This study introduces

Oncologic Safety of Facial‐Vessel–Based Buccinator Myomucosal Flaps for Tongue and Oral Floor Reconstruction: A Retrospective Multicenter Case–Control Study

Head &Neck, EarlyView.
ABSTRACT Background Buccinator myomucosal flaps (BMFs) have been proposed as a reconstructive solution for defects of the tongue and oral floor; however, their harvest requires preservation of the facial artery and vein. This study aimed to evaluate the oncologic safety of this approach compared with free fasciocutaneous flaps (FFF).

Elucidating the origin of open‐circuit voltage in ternary organic solar cells with a nonfullerene and a fullerene acceptor

InfoMat, EarlyView.
Fullerenes tend to alloy with polymer:nonfullerene acceptor hosts, yielding composition‐dependent increases in open‐circuit voltage while recombination remains governed by the charge‐transfer state energy and is independent of the nature of the third component.
