Modulating Iridium Electronic Structure With High‐Valent Metal Doping for Efficient and Durable Acidic Oxygen Evolution Reaction

Advanced Functional Materials, EarlyView.
We synthesized a novel IrCuOx/MnO2 heterostructure co‐doped with high‐valent W and Mo atoms, achieving exceptional acidic stability and high mass activity. Owing to the synergistic effects of structural and electronic modulation, cooperative charge redistribution occurs across both the interface and the lattice.

Solvent‐Free Manufacturing of Multifunctional Gas Diffusion Electrode Architectures for Enhanced CO2 Conversion From Low‐Concentration Streams

Advanced Functional Materials, EarlyView.
A tandem gas diffusion electrode (GDE) leveraging hierarchically engineered microgranules enables efficient CO2 electroreduction under dilute CO2 conditions. A key innovation lies in the solvent‐free precision assembly of metal–organic‐frameworks, carbon nanotubes, and copper nanoparticles.

Feedback Processes and Climate Response [PDF]

, 1990
The response of the climate system to an external perturbation--e.g., a change in solar irradiance or a change in atmospheric opacity due to an increase in CO2--depends rather strongly on feedback processes in the system, which either amplify or dampen ...
