Electrolyte Transport Parameters and Interfacial Effects in Calcium Metal Batteries: Analogies and Differences to Magnesium and Lithium Counterparts

open access: yesAdvanced Science, EarlyView.
Mg and Ca metal batteries represent promising alternatives to Li‐based batteries. Due to their position in the periodic table, the metals and their corresponding cations share commonalities, which lead to similarities but also differences in terms of electrolyte transport properties and interfacial processes.

Magnetically Compensated Nanometer‐Thin Ga‐Substituted Yttrium Iron Garnet (Ga:YIG) Films with Robust Perpendicular Magnetic Anisotropy

open access: yesAdvanced Electronic Materials, EarlyView.
This study reports on the remanent magnetization 4πMr and the temperature dependence of the net magnetization of magnetically compensated Ga:YIG films. For samples with very low net magnetic moments, the compensation points Tcomp and the Curie temperatures TC are determined. Ga:YIG films exhibit a significant increase in effective magnetization 4πMeff,

Highly Active IrRuOx/MnOx Electrocatalysts with Ultralow Anode PGM Demand in Proton Exchange Membrane Electrolyzers

open access: yesAdvanced Energy Materials, EarlyView.
MnOx‐supported IrRuOx exhibits outstanding OER performance in both liquid electrolytes and real cell environments. The MnOx not only enhances the dispersion of IrRuOx but also induces a compressive strain effect. The incorporation of Ru leads to surface reconstruction.

The Effect of Pore Functionality in Multicomponent Covalent Organic Frameworks on Stable Long‐Term Photocatalytic H2 Production

open access: yesAdvanced Energy Materials, EarlyView.
Five COFs are synthesized through a multicomponent reaction, preserving a similar backbone while introducing varying pore functionalities. All COFs demonstrate excellent chemical stability and sustained H2 production under sunlight for 7‐15 days. The imidazole‐functionalized COF exhibits the highest H2 production, which can be attributed to its high ...
