MOFs als neue katalytische Plattform für kovalente adaptive Netzwerke: Katalyse trifft Verstärkung

Angewandte Chemie, EarlyView.
Eine neu entwickelte, heterogene, katalytische Plattform für kovalente adaptive Netzwerke (CANs) wird vorgestellt. Dies wird erreicht durch die Immobilisierung von Basen mit geringem Molekulargewicht auf metallorganischen Gerüstverbindungen (MOFs). Der erhaltene Katalysator UiO‐TBD profitiert von der hohen Beladungskapazität von MOFs und demonstriert ...

Geological processes shaping freshwater biodiversity: a synthesis of global evidence

Biological Reviews, EarlyView.
ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

Extent, characteristics and policy applications of Key Biodiversity Areas

Biological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy
