Sensitized Disequilibration of Water‐Soluble Azopolymers

open access: yesAngewandte Chemie, EarlyView.
Disequilibration by sensitization under confinement (DESC) is a promising strategy for efficient visible‐light‐induced azobenzene E→Z isomerization. In this article, we explored key factors for adapting DESC to azopolymers, eventually achieving efficiencies up to 85% compared to direct excitation and laying the foundation for more complex systems ...

Machine Learning‐Enhanced Clinical Decision Support for Diagnosing Sinusitis With Nasal Endoscopy

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Sinusitis is a prevalent disease for which nasal endoscopy (NE) is an optimal diagnostic modality. However, NE accuracy is limited by inter‐operator variability in landmark identification and localization of mucus that is necessary for sinusitis diagnosis. We sought to develop a novel multi‐class machine learning (ML) framework that

Tin—Tin π Bonding as a Conduit for Alkali‐Metal Reduction

open access: yesAngewandte Chemie, EarlyView.
Reactions of the doubly reduced distannynes, [Ar′SnSnAr′M2], (Ar′ = C6H3‐2,6‐Dipp; M ═ ′Li, Na, K), with the successively heavier alkali metals (M) result in reduction of M, which is proposed to occur via a suitably disposed π* SOMO of the putative radical anions, [Ar′SnSnAr′M2]•−.

Back Again to the Future: A New Era for Cerebroprotection

open access: yesAnnals of Neurology, EarlyView.
Cerebroprotection is a fresh framework for designing neurological therapy that targets glia and vascular cells, in addition to neurons. In the future, successful cerebroprotection will involve targeting all elements of the neurovascular unit. Preclinical trials must include functional outcomes, as well as lesion morphometry.

Electrochemical Degradation of Perfluoroalkyl Sulfonates via Sulfonate to Carboxylate Conversion

open access: yesAngewandte Chemie, EarlyView.
We demonstrate a novel approach for the degradation of perfluoroalkyl sulfonic acids (PFSAs) involving a controlled, electromediated, sulfonate‐to‐carboxylate headgroup conversion. We apply this method to shorter chain PFSAs and provide key mechanistic insights that contribute to a broader understanding of the molecular pathways underlying pollutant ...

CHASE BY AND TRANSFORMATION OF THE SHAMAN FROM TOMSKAYA PISANITSA

open access: yesВестник Кемеровского государственного университета, 2013
The paper addresses a Tomskaya Pisanitsa composition. Based on ethnographic parallels and attributes of characters, a new interpretation of the scene with an anthropomorphic character and an elk cow is presented.
