Interface Engineering of Porous Transport Layer‐Catalyst Layer in Proton Exchange Membrane Water Electrolyzers: A Comprehensive Review

open access: yesAdvanced Materials Interfaces, EarlyView.
The PTL–CL interface plays a decisive role in PEMWE performance by governing electron conduction, water supply, oxygen removal, catalyst utilization, and interfacial stability. This review summarizes interface‐related resistance sources, characterization methods, and engineering strategies, highlighting rational PTL–CL interface design for low‐cost ...

Investigations of the Evolved Molecular Basis for Terpenoid Biosynthesis in Marine Sponges

open access: yesAdvanced Science, EarlyView.
Confirming and extending a previous observation in another Bubarida sponge, genomic and functional analyses of A. cavernosa reveal that sponges retain the mevalonate pathway and employ single α‐domain T1TSs and UbiA‐type TSs for terpenoid biosynthesis. The absence of T1TSs clustering with other biosynthetic genes tentatively suggests, based on limited ...

Evolutionary relationship between organellar DNA inheritance patterns and traits of seed plants

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise In plants, organellar DNA is predominantly maternally inherited, but biparental and paternal inheritance have also been observed. Specific mechanisms, such as plastid exclusion during pollen mitosis or genome degradation, ensure maternal inheritance.

Methanolzersetzung auf TiO2 unter Umgebungsbedingungen: Kooperativer Protonentransfer an hydratisierten Grenzflächen

open access: yesAngewandte Chemie, EarlyView.
Unter Umgebungsbedingungen wird die TiO2‐Oberfläche durch adsorbierte Hydroxylgruppen (OH) und Wassermoleküle hydratisiert. Diese Oberflächenhydratation fördert die Methanolzersetzung und macht den ersten Deprotonierungsschritt im Vergleich zu idealen UHV‐Bedingungen nahezu barrierefrei. Unter UV‐Beleuchtung erleichtert die Oberflächenhydratation zudem

Local knowledge and management of the royal fern (Osmunda regalis L.) in Northern Spain: implications for biodiversity conservation [PDF]

open access: yes, 2009
This study reports the harvesting, management, trading and use of the royal fern (Osmunda regalis) in Cantabria (Spain), where medicinal plant gathering has been mainly abandoned and nowadays only few species are still commonly gathered.

Konstruktion hochselektiver Bindungstaschen in UiO‐Typ‐MOFs mittels verbrückter Linker

open access: yesAngewandte Chemie, EarlyView.
Großer Gestaltungsspielraum: Es wird eine generelle Strategie für die präzise ortsspezifische Modifikation von UiO‐Typ‐MOFs mit funktionellen Gruppen vorgestellt. Durch den Einsatz von vorverbrückten oder pre‐connected Linkern werden gezielt taschenartige Poren für die molekulare Erkennung erzeugt, deren hohe Affinität gegenüber aliphatischen ...
