Advanced Materials, EarlyView.We report perovskite photodetectors with record specific detectivities exceeding 1013 Jones with a novel molecular design strategy to functionalize self‐assembled monolayers (SAMs) with ferrocene (Fc) derivatives. Fc‐SAM‐based devices also exhibit strong operational stability and enable data transmission rates exceeding 1 Mbps in a LiFi system ...

Effects of Time-Varying Relative Spectral Response on the Calibration of MODIS Reflective Solar Bands [PDF]
, 2018 Calibration of the on-orbit gain changes of the narrow bandwidth reflective solar bands (RSB) of Terra and Aqua MODIS is usually based on the band center wavelength. The relative spectral response (RSR) of each band is assumed to be constant on orbit and

Phase‐Engineered MoS2 Quantum Monolayer Catalysts
Advanced Materials, EarlyView.A new type of catalyst model—phase‐engineered MoS2 quantum‐monolayer catalyst (∼0.8 nm thick, < 6 nm in the lateral size; switchable freely among metallic 1T, semiconducting 2H, and a hybrid phase of metallic‐semiconducting 1T‐2H)—is reported. It can efficiently and stably drive photochemical H2, syngas and ammonia synthesis as a catalyst or co ...

Improvements of VIIRS Reflective Solar Bands (RSB) Solar and Lunar Calibration [PDF]
, 2014 The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument on-board the Suomi-NPP satellite has successfully operated for more than 2 years since its launch in October, 2011. VIIRS has 15 reflective solar bands (RSB) with wavelengths ranging from 0.

The Effects of Solar Irradiance Spectra on Calculation of Narrow Band Top-of-Atmosphere Reflectance
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2014 Extraterrestrial solar irradiance spectra detail the solar energy distribution over wavelengths, and numerous solar irradiance models are available within the remote sensing community. However, reference spectra may differ widely owing to differences in solar activity, measurement instruments and calibration.

, 1986 Solar ovens work much like solar collectors used in domestic water heating systems. Both collect solar radiation, convert it to heat and transfer it to another substance. Solar ovens, however, focus the sun\u27s rays with reflective surfaces on one point.

Advanced Materials, EarlyView.Ionic cocrystal‐programmed ionic organization establishes a general strategy for electrostatic programming in polymeric photocatalysts. ABSTRACT Controlling the spatial organization of ions in polymeric photocatalysts remains a fundamental challenge for optimizing charge transport and catalytic selectivity in solar‐driven hydrogen peroxide (H2O2 ...

Pre-Launch JPSS-2 VIIRS Response versus Scan Angle Characterization
Remote Sensing, 2017 On-orbit whisk-broom sensors have scanning mirror assemblies, whose reflectance variations with scan angle must be characterized prior to launch. One such instrument is the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Joint Polar ...

Charge Storage and Dark Photocatalysis in Multivariate Ti‐Based Metal‐Organic Frameworks
Advanced Materials, EarlyView.The mixed‐linker series of the titanium‐based metal–organic framework COK‐47 enables systematic tuning of photoresponsiveness and (dark) photocatalytic activity, deepening our understanding of structure‐property‐function relationships. Tailored metal‐to‐ligand charge transfer between the secondary building units (metal‐oxo layers and organic linkers ...
