Ionic Gating of Liquid‐Crystal‐Like Pteridine Assemblies Enables Tunable Light Scattering

Advanced Materials, EarlyView.
Tunable optical properties emerge through developmentally regulated ionic gating, which transforms disordered, ultraviolet (UV)‐absorbing organelles into concentrically ordered, liquid‐crystal‐like light scatterers. By integrating analyses of pteridine composition, potassium‐dependent assembly, hierarchical ultrastructure, and optical behavior, the ...

Dual Single Atoms Boosting Photocatalytic Upcycling of Raw Polyvinylidene Fluoride Plastic

Advanced Materials, EarlyView.
To resolve the catastrophic disaster of plastic contamination, the Cu‐Fe dual‐single‐atom‐loaded In2P3S9 NSs photocatalyst was prepared for direct conversion of raw polyvinylidene fluoride plastic into valuable chemicals. The dual‐single‐atom catalyst exhibits exceptional performance, with a total acetic/formic acid production of ∼1351.8 µmol g−1 ...

Recovery of pixels with extremely turbid waters and intensive floating algae from false cloud masking in satellite ocean color remote sensing

International Journal of Applied Earth Observations and Geoinformation
We describe our work to improve the cloud masking for satellite ocean color data processing over extremely turbid waters and intensive algae blooms (or floating algae), which are often identified as cloud mistakenly. An improved cloud masking approach is

Validation and Intercomparison of Ocean Color Algorithms for Estimating Particulate Organic Carbon in the Oceans

Frontiers in Marine Science, 2017
Particulate Organic Carbon (POC) plays a vital role in the ocean carbon cycle. Though relatively small compared with other carbon pools, the POC pool is responsible for large fluxes and is linked to many important ocean biogeochemical processes.
