Origin of Dark Current Robustness in Photomultiplication Organic Photodetectors Enabled by Ionic Conjugated Electron‐Blocking Layers

Advanced Materials, EarlyView.
Ionic conjugated polyelectrolyte electron‐blocking layers enable photomultiplication organic photodetectors with dark current robustness up to −10 V and external quantum efficiencies exceeding 3000%. Fowler–Nordheim tunneling, interfacial dipole, trap density of states, and noise analyses reveal how ionic conjugated polyelectrolytes suppress electron ...

Cu‐Pd Dual Single Atoms Promoting Selective CO2 Photoreduction to C2 Products in Seawater

Advanced Materials, EarlyView.
Cu and Pd dual single atoms anchored on TiO2 cooperatively enhance C─C coupling during CO2 photoreduction in seawater. Under xenon‐light irradiation and without a sacrificial reagent/alkaline trapping agent, the catalyst achieves highly selective acetic acid formation.

Thermal Spectra of Warped and Broken Accretion Disks

The Astrophysical Journal
Black holes may accrete gas with angular momentum vectors misaligned with the black hole spin axis. The resulting accretion disks are subject to Lense–Thirring precession, and hence torque. Analytical calculations and simulations show that Lense–Thirring

Electrocatalyst/Semiconductor Interfaces in Photoelectrocatalysts: Mechanistic Analysis of the Impact of Nanoparticle Electrocatalyst Coverage on Performance

Advanced Materials, EarlyView.
Reducing Ni nanoparticle coverage on n‐Si photoanodes enhances photovoltage by promoting thicker interfacial SiOx formation during photoelectrochemical oxygen evolution reaction (OER). Experiments, analytical modeling, and finite‐element simulations reveal that coverage‐dependent chemical interface evolution, rather than geometric effects alone ...

Fabrication of TiN/TiO2 Nanotube‐Based Heterostructure for Hydrogen Sensing Applications

Advanced Materials Interfaces, EarlyView.
A hydrogen sensor based on titanium dioxide nanotubes coated with titanium nitride has been developed. The coating process causes a mixed titanium oxynitride layer to form, which improves the sensor performance. Sensor response R depends on the TiN thickness and is not degraded after 7 days in air.

Binary Black Hole Mergers and Intermediate-mass Black Holes in Dense Star Clusters with Collisional Runaways

The Astronomical Journal
Intermediate-mass black holes (IMBHs) are believed to be the missing link between the supermassive black holes (BHs) found at the centers of massive galaxies and BHs formed through stellar core collapse. One of the proposed mechanisms for their formation

Low‐Temperature Gold Deposition Improves CdTe Back Contacts

Advanced Materials Interfaces, EarlyView.
Cd(Se,Te) samples are cooled during the evaporation of Au back contacts to thermally quench CdTe degradation. Reduced temperature during Au evaporation boosts PV efficiency, open‐circuit voltage, and fill factor. XPS associates these improvements with less chemical perturbation of the CdTe surface during metallization.
