Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)

open access: yesAngewandte Chemie, EarlyView.
Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote

The potency of native postbiotics and paraprobiotics in modulating inflammation by affecting the gut–kidney axis

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Native postbiotics and paraprobiotics derived from Lactobacillus and Bifidobacterium strains were administered to dextran sulfate sodium–treated C57BL/6 mice to evaluate their impact on kidney inflammation via the gut–kidney axis. Histological analysis and quantitative polymerase chain reaction of autophagy‐related genes (atg5, atg7, atg12, atg13 ...

Glutaredoxine reduzieren schnell Glutathionhydroper‐ und Glutathionpolysulfide

open access: yesAngewandte Chemie, EarlyView.
Glutaredoxine (Grx) reduzieren Glutathionpolysulfide (GSSnSG) schnell zu Glutathionhydroper/polysulfiden (GSSnH) oder GSSnH zu Wasserstoff(poly)sulfiden (H2Sn). Die Reduktion glutathionylierter Grx durch reduziertes Glutathion (GSH) liefert Glutathiondisulfid (GSSG).

Diamondiyne: A 3D Carbon Allotrope With Mixed sp–sp3 Hybridization

open access: yesAngewandte Chemie, EarlyView.
A new carbon allotrope with mixed sp–sp3 hybridization has been synthesized through delicately controlled kinetics at a liquid–liquid interface. The resulting material, termed diamondiyne, exhibits an expanded diamond‐type network in the form of small crystallites in a continuous all‐carbon film.

CO‐Adsorption auf MgO in neuem Licht: polarisationsaufgelöste Infrarotspektroskopie identifiziert Stufenkanten als dominierende Defekte auf MgO(100) und MgO(110)

open access: yesAngewandte Chemie, EarlyView.
Durch die Kombination von polarisationsaufgelöster IRRAS mit hybriden HSE06‐DFT‐Berechnungen ermitteln wir platzspezifische Schwingungsfingerabdrücke, Adsorptionsgeometrien und Bindungsenergien für CO auf MgO‐Oberflächen mit großer Bandlücke. Niedrig koordinierte Mg4c2+‐Stufenkantenplätze werden anstelle von Schottky‐Defekten auf Terrassen als die ...

Chemical Switching Between B2N and B2C Homoaromaticity

open access: yesAngewandte Chemie, EarlyView.
We report the synthesis of homoaromatic 1‐aza‐2,4‐diazadiboretane with a bicyclic four‐membered NB2C motif and demonstrate experimentally and theoretically that the homoaromatic delocalization can also be chemically shifted from the B2N to the B2C moiety by deprotonation of the ring carbon atom.

Intramolecular Nickel‐Catalyzed Reductive Coupling: Enantioselective Synthesis of Tetrahydroisoquinolines and Related Heterocycles

open access: yesAngewandte Chemie, EarlyView.
The successful extension of the nickel‐catalyzed asymmetric coupling of polarized 1,3‐dienes with aldehydes to an intramolecular setting opens an efficient new entry into hydroxylated N‐heterocyclic compounds, most notably valuable tetrahydroisoquinolines.

In Vitro Callus Induction and Embryogenesis of Oil Palm (Elaeis guineensis Jacq.) from Leaf Explants

open access: yesHayati Journal of Biosciences, 2011
This research was to study in vitro callus induction and somatic embryogenesis in oil palm from leaf explants. Young leaf segments from mature oil palm were cultured on MS medium supplemented with different concentrations of 2,4-D with or without ...

Deprotektive Alkylierung: Eine Plattform zur Umsetzung von Alkoholen zu Aminen mittels Nonafluormesitylensulfonamiden

open access: yesAngewandte Chemie, EarlyView.
Die direkte Umwandlung von Alkoholen in tertiäre oder sekundäre Amine in einem Reaktionsschritt unter Verwendung von Nms‐Amiden wird beschrieben. Die Transformation zeichnet sich durch eine breite Toleranz gegenüber verschiedenen funktionellen Gruppen und eine hohe Stereospezifität aus, was ihre Eignung für die Synthese isotopenmarkierter Arzneimittel ...
