Angewandte Chemie, EarlyView.Nach einer weitverbreiteten Annahme erfährt der Cobalt‐basierte Fischer‐Tropsch‐Katalysator eine anfängliche Aufrauung, die zu einer Aktivitätssteigerung führt und vom hohen chemischen Potential des Kohlenstoffs getrieben wird. In der vorliegenden Operando‐STM‐ und DFT‐Untersuchung simulieren wir solche Bedingungen.

The political ecology of late South American pastoralism: an Andean perspective A.D. 1,000-1,615
Journal of Political Ecology, 2018 Prehispanic South American pastoralism has a long and rich, though often understudied, trajectory. In this paper, we analyze the transition from a generalized to a specialized pastoralism at two geographical locations in the Andes: Antofagasta de la ...

Angewandte Chemie, EarlyView.CYB5R3 wird als mutmaßlicher Elektronentransferpartner von Viperin (RSAD2) identifiziert, was erklärt, warum die ER‐Lokalisation für die antivirale Aktivität erforderlich ist. Dieses Wissen ermöglichte die Entwicklung immunstiller, katalytisch selbstversorgender antiviraler Restriktionsfaktor‐Enzyme (iCAREs), die ein antivirales Nukleosidtriphosphat ...

Archaeological Prospection, EarlyView.ABSTRACT High‐resolution and accurate synoptic images of terrestrial topography, even in densely forested areas, have proven valuable for archaeology by enabling the identification and characterization of relief patterns associated with ancient human activities. This study presents a novel approach that integrates digital terrain models (DTMs) obtained

Ecography, EarlyView.Despite having only about 670 species worldwide, conifers are one of the ecologically and economically most important plant groups. They have a rich fossil record and previous studies have shown that their current diversity is the result of past radiations, extinction, and dispersal events, restricting many genera to either the Northern or Southern ...
