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

Advanced 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

Advanced 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 ...

Comparative analysis of leaf desiccation of 21 coexisting tropical fern species

Botan‪ical Sciences
Background: Ferns are distributed worldwide and exhibit high species diversity in humid tropical regions, particularly in cloud forests. Ferns have remarkable adaptations and life forms, but their association needs to be better understood. Question: Are

Methanolzersetzung auf TiO2 unter Umgebungsbedingungen: Kooperativer Protonentransfer an hydratisierten Grenzflächen

Angewandte 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

Critical assessment issues in work-integrated learning [PDF]

, 2014
Assessment has long been a contentious issue in work-integrated learning (WIL) and cooperative education. Despite assessment being central to the integrity and accountability of a university and long-standing theories around best practice in assessment ...

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

Angewandte 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 ...

Hierarchische Membran zur photoelektrostatisch gesteuerten Trennung ein‐ und zweiwertiger Ionen

Angewandte Chemie, EarlyView.
Wir berichten über eine hierarchische, auf anodischem Aluminiumoxid getragene Poly(ionische Flüssigkeit)‐Kohlenstoffnitrid‐Membran zur effizienten Trennung ein‐ und zweiwertiger Ionen. Räumlich begrenzte Nanokanäle und gezielt eingestellte Ion‐Grenzflächen‐Wechselwirkungen ermöglichen außergewöhnlich hohe K+/Mg2+‐ (>500) und Li+/Mg2+‐Selektivitäten ...
