High‐Density Topological Defect Array by Two‐Step Interference Photoalignment

open access: yesAdvanced Materials, EarlyView.
High density arrays of topological defects in nematic liquid crystal are realized by two‐step interference photoalignment, with a minimal distance of 1.25 micrometer and disclination lines connecting defects on opposing substrates. Such layers can be used as reconfigurable templates for photonic devices to achieve large angle diffraction, beam shaping ...

Oxygen Evolution Reaction Catalysts for Acidic‐Media CO2 Electrolyzers

open access: yesAdvanced 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.

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

open access: yesAdvanced 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

Cr2AlC: A High‐Temperature Transparent Conducting Ceramic

open access: yesAdvanced Materials Interfaces, EarlyView.
The high‐quality epitaxial Cr2AlC(0001) layer combines a low resistivity of 42.5 µΩcm, 84% optical transmittance at 900 nm, and thermal stability up to 800–1100°C. It stands out as an excellent high‐temperature transparent conductor with a negligible resistivity size effect, exceptional scaling (ρoλ < 3 × 10−16 Ωm2), and a figure of merit of 0.004 Ω−1.
