Unsuccessful Coupling of Weakly Coordinating Anion–Based Mg Salts and Alkoxyalkylamine Solvents for Rechargeable Mg Battery Application: Trace Water‐Driven Interfacial Failure

open access: yesAdvanced Science, EarlyView.
Combining recently established two ground‐breaking concepts, the adoption of WCAs and the use of alkoxyalkylamine‐based solvents in electrolyte formulations for rechargeable magnesium metal batteries, has led to unexpectedly unsuccessful electrochemical Mg plating/stripping performance. Comprehensive experimental and computational analyses revealed the

Atomic‐Layer‐Deposited ZnF2 on Aluminum Enabling In Situ NaF/Na–Zn Interphase for Robust Anode‐Free Sodium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
“Sodiation of an ultrathin ALD‐ZnF2 layer on an Al current collector generates a sodiophilic Na–Zn alloy and a NaF‐rich SEI, enabling uniform Na deposition and highly reversible anode‐free sodium batteries.” ABSTRACT Achieving high‐energy‐density “anode‐free” sodium batteries remains a daunting challenge due to rapid capacity decay caused by poor ...

Beyond the Gold Standard: Towards Industrially Viable Electrodes for Durable Perovskite Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Transparent and opaque electrode materials are mapped by raw material cost per 1 m2 electrode area and retained median device efficiency after heat–light ageing. FTO offers a lower‐cost and more stable alternative to ITO, while Cr/Al provides the lowest‐cost rear electrode investigated with Au‐like stability and substantially improved durability ...

Regional gas exchange evaluation during ex vivo lung perfusion in a swine model of localized lung dysfunction

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Abstract Background Ex vivo lung perfusion (EVLP) allows the evaluation of lungs that do not meet standard transplantation criteria. Current procedures do not permit the identification of regional functional deficits. We investigated the feasibility of assessing lobar gas exchange during EVLP in a swine model.

Zähmung eines blauen Gases—Struktur und Chemie von Hexafluorthioaceton

open access: yesAngewandte Chemie, EarlyView.
Hexaflouorthioaceton (1), ein blaues Gas bei Raumtemperatur, wurde durch Vakuumpyrolyse des zyklischen Dimers bei 660 °C synthetisiert. Wir diskutieren grundlegende Eigeschaften des schwer greifbaren 1, einschließlich Einkristallstruktur und Kernmagnetische Resonansspektroskopie, obwohl es eine starke Tendenz zur Dimerisierung selbst bei –74 °C zeigt ...

Cycloazulenylen

open access: yesAngewandte Chemie, EarlyView.
Ein ausschließlich aus Azulen‐Untereinheiten aufgebauter gespannter Makrocyclus mit der Bezeichnung [6]Cycloparaazulenylen ([6]CPA) wird vorgestellt. Der Makrocyclus weist für ein Azulensystem eine bemerkenswert kleine HOMO–LUMO‐Energielücke, eine durch die Ringspannung hervorgerufene bathochrome Verschiebung der Absorption sowie ein ungewöhnliches ...

Erste Hinweise auf Ozonido‐TMC‐Komplexe von Eisen und Kobalt

open access: yesAngewandte Chemie, EarlyView.
Die Umsetzung der Eisen(II)‐Komplexe [(TMC)Fe(OTf)]BArF und [(D12‐TMC)Fe(OTf)]BArF sowie der Kobalt(II)‐Komplexe [(TMC)Co(OTf)]BArF und [(D12‐TMC)Co(X)]BArF (X = OTf, F) mit Ozon führt in einem 4:1‐Gemisch aus 2‐Me‐THF und THF bei Temperaturen bis −155°C zur Bildung von Ozonido‐ und Oxido‐Komplexen.
