Understanding the Interplay Between Thermal Activation, Diffusion, and Phase Segregation of Molecular Dopants Blended with Polymeric Semiconductors

Advanced Electronic Materials, EarlyView.
The use of air stable but thermally labile molecules provides an efficient strategy for the N‐type doping of organic semiconductors with relatively low electron affinities. Design criteria for efficient dopants should also take into account diffusion and phase segregation that cannot be decoupled from thermally activated doping.

Shaping of a Reactive Manganese Catalyst Enables Access to Polyfunctionalized Cyclohexanes via Enantioselective C(sp3)─H Bond Oxidation of 1,3‐meso Diethers

Angewandte Chemie, EarlyView.
Structural shaping of a highly reactive chiral Mn‐oxo species translates into exceptionally enantioselective C─H oxidation catalyst of cyclohexyl 1,3‐meso diethers (up to >99% ee) leading to polyfunctionalized cyclohexanes. Abstract Chiral polyoxygenated cyclohexanes are valuable constituents of biologically relevant products.

Sulfonated para‐Polybenzimidazole Membranes for Use in Vanadium Redox Flow Batteries

Advanced Energy Materials, EarlyView.
Dense sulfonated para‐PBI membranes (MS‐PBI) are tested in the VRFB. The conductivity is 10 times lower than reported for MS‐PBI gel membranes, but 10 times higher than that of meta‐PBI. The influence of membrane preparation process, thickness, and operating temperature on the VRFB performance is investigated.

Gut microbiota–derived short‐chain fatty acids regulate group 3 innate lymphoid cells in HCC

Hepatology, EarlyView., 2022
Abstract Background and Aims Type 3 innate lymphoid cells (ILC3s) are essential for host defense against infection and tissue homeostasis. However, their role in the development of HCC has not been adequately confirmed. In this study, we investigated the immunomodulatory role of short‐chain fatty acids (SCFAs) derived from intestinal microbiota in ILC3

Structural Origin of Spin‐Orbit Splitting of 1P Orbitals of Icosahedral Au13 Superatom Protected by Ligands

Angewandte Chemie, EarlyView.
The spin‐orbit (SO) splitting of the superatomic 1P orbitals in thiolate‐protected Au13 superatoms were investigated. Cryogenic anion photoelectron spectroscopy and fully relativistic calculation including SO coupling revealed the 1P orbitals of the Au13 and Au@Ag12 superatomic cores undergo SO splitting, while not in the Ag13 core.

Sulfonated Polybenzimidazole Membranes: How Sulfonation Affects Properties, Stability, and Performance in Vanadium Redox Flow Batteries

Advanced Energy Materials, EarlyView.
Sulfonation of OPBI increases the electrolyte uptake and thus increases the conductivity. Simultaneously, the more open structure increases access to vanadium ions. However, it appears that sulfonation deactivates the sites which are attacked by VO2+. This allows stable and highly efficient vanadium redox flow batteries.

Pbs2 regulates late‐stage macroautophagy in Saccharomyces cerevisiae

Animal Models and Experimental Medicine, EarlyView.
The MAPK family member Pbs2 and its role in autophagy. Macroautophagy consists of five key steps: the initiation at the pre‐autophagosomal structure (PAS), elongation of the isolation membrane (IM), maturation of the autophagosome, fusion of autophagosomes with vacuoles, and degradation of autophagic bodies.

La résistance aux benzimidazoles des nématodes gastro-intestinaux des petits ruminants en Gambie et au Sénégal

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1998
Cinquante-cinq troupeaux de petits ruminants en Gambie et au Sénégal ont été examinés en utilisant le test d'inhibition de l'éclosion des œufs et/ou le test de réduction des œufs de nématodes dans les fèces afin de détecter une résistance éventuelle aux

Photochemische Permutation von Indazolen zu Benzimidazolen

Angewandte Chemie, EarlyView.
Hier stellen wir eine photochemische Strategie für die direkte Permutation von 1H‐ und 2H‐Indazolen zu Benzimidazolen vor. Dieser Ansatz beruht auf einem zweistufigen Mechanismus aus Tautomerisierung im angeregten Zustand und photochemischer Umlagerung, bietet einen breiten Anwendungsbereich, hohe Ausbeuten und funktionelle Gruppentoleranz und erhöht ...

An Insight into Practices Associated with the Control of Internal Parasites in the Dairy Goat Herds of Romania: A Questionnaire Survey

Animals
The widespread and uncontrolled use of anthelmintic products has contributed to the emergence of anthelmintic resistance (AR). This phenomenon globally threatens the productivity and welfare of small ruminants.
