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 ...

Temperature Correction in a Single Luminophore Pressure‐Sensitive Paint Using a Dual‐Emitting Gold Acridine Complex

Advanced Optical Materials, EarlyView.
The use of pressure‐sensitive luminescent molecules to quantify surface pressure in wind tunnel testing has revolutionized experimental aerodynamics. This work develops a dual‐emitting gold acridine complex for the simultaneous sensing of pressure and temperature independently of each other.
