Retrieval of global aerosol and surface properties from the Gaofen-5 Directional Polarimetric Camera measurements [PDF]

open access: yesAtmospheric Measurement Techniques
Multi-angle polarimetry has been recognized as the most effective configuration to retrieve aerosol parameters from space. In this study, we developed a numerical inversion algorithm that simultaneously retrieves aerosol optical depth (AOD), single ...

The dayglow of the O2 atmospheric band system [PDF]

open access: yes, 1986
The dayglow of the O2 atmospheric band system has been simulated by taking into account the three main production mechanisms of the O2(1[Sigma]) state: resonance fluorescence, a photochemical term due to quenching of O(1D), and a pure chemical process ...

Carbon Dot Nano‐Spacers in Triazine Networks for Integrated Photothermal Seawater Desalination and H2O2 Production

open access: yesCarbon Energy, EarlyView.
Cyanated carbon dots (CN‐CDs) are synthesized by the hydrothermal method with carboxymethyl cellulose and cyanobenzoic acid, and CD‐CTN is obtained in situ via cyclotrimerization of CN‐CDs. CD‐CTN possesses excellent photothermal catalytic H2O2 production in seawater, and desalted H2O2 could be obtained, which demonstrates the practical application for

Fe Atoms Accelerator Coupled With Oxygen Vacancies Channel Synergistically Boost OER Performance of Fe‐CoMoO4‐Ov Nanosheets

open access: yesCarbon Energy, EarlyView.
Fe‐CoMoO4‐Ov/NF demonstrates significantly improved OER catalytic performance compared to CoMoO4. Specifically, the introduced Fe atoms act as a promoter for surface reconstruction, significantly reducing the energy required for surface reconstruction to generate FeCoOOH. The oxygen vacancies serve as electron channels between the core Fe‐CoMoO4‐Ov and
