Chiral Metal Halide Perovskites for Spin‐Polarized Light‐Emitting Diodes

Advanced Materials, EarlyView.
Chiral metal–halide perovskites offer a route to circularly polarized light without external polarizers. This Perspective compares two spin‐light emitting diode concepts: intrinsically chiral emissive layers and chiral spin‐filter interlayers that inject spin‐polarized carriers into efficient achiral emitters.

Oxygen Evolution Reaction Catalysts for Acidic‐Media CO2 Electrolyzers

Advanced Materials, EarlyView.
Acidic‐media CO2 electroreduction (CO2R) could decarbonize chemical production, despite relying on rare‐earth elements for anodic oxygen evolution reaction (OER). Transferring the learnings from mature sister technologies (water electrolysis) could accelerate technological development.

Vacuum‐Evaporated, Lead‐Free RbYbI3 Perovskite Interlayers for Universal Electron Injection in High‐Performance Organic Light‐Emitting Diodes

Advanced Materials, EarlyView.
ABSTRACT The optoelectronic performance of organic light‐emitting diodes (OLEDs) is critically governed by charge injection from electrodes into organic layers, where significant energy barriers at the interfaces often impede efficient charge injection.

Understanding the Dynamics of Nanoparticle Formation and Evolution in Functional Oxides via In Situ SAXS/WAXS

Advanced Materials Interfaces, EarlyView.
In situ SAXS/WAXS enables real‐time tracking of nanoparticle formation and evolution in exsolved and infiltrated Ni‐based perovskites under reducing conditions. The combined technique captures nucleation, growth, and coarsening dynamics with high temporal resolution, providing statistically robust insights into structural and morphological ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery
