Determining Composition–Structure–Property Relationships in Quaternary Perovskitoids Through Megalibraries

Advanced Materials, EarlyView.
A method to synthesize 1 million compositionally distinct Cs3Bi2‐𝛼Sb𝛼Br9−xIx across a quaternary compositional space on a single glass substrate is presented. High‐throughput characterization is then used to map the interplay of composition, structure, and bandgap.

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

Oxygen‐Controlled Structural and Defect Engineering of Magnetron‐Sputtered ZnO Thin Films for Photosensing

Advanced Materials Interfaces, EarlyView.
Zinc oxide thin films are engineered by controlling oxygen flow and nominal partial pressure during growth to tune atomic‐scale defects and crystallographic texture that limit device performance. By balancing competing defects, the films achieve improved preferential c‐axis orientation and enhanced ultraviolet photoresponse.
