Efficient Osmotic Energy Conversion Enabled by Self‐Standing COF Membranes With Varied Sulfonic Acid Group Density

Advanced Materials, EarlyView.
Self‐standing, strong sulfonated covalent organic framework membranes with varied ionic‐group density are developed for osmotic energy conversion. Optimized charge‐governed nanochannels enable highly selective ion transport, delivering a power density of 24.53 W m−2 under seawater/freshwater salinity gradients.

Energy Band Alignment and Electro‐Optical Behavior of Nearly Unstrained Monolayer MoS2 Heterostructures With GaN

Advanced Materials Interfaces, EarlyView.
Large size (∼100 µm) monolayer MoS2 grown by LPI‐CVD on n‐GaN exhibit a high n‐type doping, very low strain, and a type‐I band alignment at MoS2/GaN interface. Photocurrent measurements under illumination with photon energies from ∼2 to ∼5 eV show superior electro‐optical performances of these MoS2/n‐GaN heterojunctions as compared to Ni/n‐GaN devices ...
