Spatially Decoupling Heating and Evaporation for Convection‐Enhanced 3D Solar Evaporation With Continuous Salt Harvesting

open access: yesAdvanced Functional Materials, EarlyView.
An architecture‐enabled bottom‐heated 3D solar convective evaporator spatially decouples photothermal heating from evaporation, triggering natural convection that intensifies sidewall vapour removal and heat transfer. The system achieves significantly enhanced evaporation rates over 2D and conventional 3D designs while confining salt precipitation to ...

Empirical Polarization Distribution Models for Use in CLARREO Pathfinder-VIIRS Intercalibration

open access: yesRemote Sensing
In this work, we discuss the impact of polarized scene radiances on the intercalibration of CPF and VIIRS reflective solar bands and the mitigation of these effects using empirical Polarization Distribution Models (ePDMs).

Radiometric Stability Monitoring of the Suomi NPP Visible Infrared Imaging Radiometer Suite (VIIRS) Reflective Solar Bands Using the Moon

open access: yesRemote Sensing, 2015
The Suomi NPP (S-NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) performs the scheduled lunar roll maneuver on a monthly basis. The lunar calibration coefficients and lunar F-factor are calculated by taking the ratio of the lunar observed radiance

Steering Oxygen Activation Pathways via Redox Dual‐Defects in 2D Hydrated WO3 for High‐Yield Singlet Oxygen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
Redox dual‐defects (Cs substitution and O vacancies) in 2D hydrated WO3 steer O2 activation toward selective singlet oxygen evolution. WO‐CO achieves 8.6–15.8 times higher 1O2 production than single‐defect or pristine catalysts, enabling efficient pollutant mineralization via a pathway‐selective photocatalytic mechanism.

MODIS Aqua Reflective Solar Band Calibration for NASA’s R2018 Ocean Color Products

open access: yesRemote Sensing, 2019
Remote-sensing ocean color products have stringent requirements on radiometric calibration stability. To address a calibration deficiency in Moderate Resolution Imaging Spectroradiometer (MODIS) Aqua in recent years, the NASA Ocean Biology Processing ...

Bandgap‐Engineered AlGaAs/GaAs Heterostructures for Wavelength‐Selective Dual‐Polarity Photoelectrochemistry

open access: yesAdvanced Functional Materials, EarlyView.
Bandgap‐engineered AlGaAs/GaAs heterostructures exhibit wavelength‐selective dual‐polarity photoelectrochemistry, switching from photocathodic to photoanodic response depending on excitation wavelength. The polarity transition is governed by band‐selective absorption, built‐in electric‐field‐driven carrier transport, and interfacial charge‐transfer ...

Is It Real Type‐II or S‐Scheme? A Three‐Phase Diagnostic Protocol for Identifying Potentially Mislabeled Heterojunction Photocatalysts

open access: yesAdvanced Functional Materials, EarlyView.
Diagnostic analysis via the heterojunction validation funnel. The funnel illustrates the hierarchical stratification of 30 reported Type‐II systems based on the three‐phase, seven‐step diagnostic framework. Complete validation through all phases is achieved by only 3.3% of systems, while 96.7% lack full mechanistic validation, revealing a pervasive ...

Submicron Metasurface Reconfigured Multiband Smart Windows

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a submicron metasurface reconfigured multiband thermochromic smart window. By integrating subwavelength nanostructures into a Fabry−Perot resonator configuration, it mitigates conventional trade‐offs to simultaneously deliver high luminous transmittance and robust solar heating and radiative cooling modulation capabilities ...
