Assessment of Practical Satellite Quantum Key Distribution Architectures for Current and Near‐Future Missions

International Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 164-192, May/June 2025.
ABSTRACT Quantum key distribution (QKD) allows the generation of cryptographic keys beyond the computational hardness paradigm and is befitting for secure data transmission requiring long‐term security. The communication distance of fiber‐based QKD, however, is limited to a few hundred kilometers due to the exponential scaling of signal attenuation ...

The Effect of Water Vapor and Solar Zenith Angle on Oceanic Diurnal Warming

Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.
Abstract Oceanic diurnal warm layers have been extensively studied over the years due to their important role in a variety of geophysical disciplines. Much of this research has been dedicated to the development of predictive models of varying complexity to calculate the spatiotemporal magnitude of the effect. This manuscript presents results which show

Performance of Airborne Imaging Spectrometers for Carbon Dioxide Detection and Emission Quantification

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 7, 16 April 2025.
Abstract Carbon dioxide (CO2) emissions from strong point sources account for a significant proportion of the global greenhouse gas emissions, and their associated uncertainties in bottom‐up estimates remain substantial. Imaging spectrometers provide a capability to monitor large point source CO2 emissions and help reduce the uncertainties.

Colored Radiative Cooling: from Photonic Approaches to Fluorescent Colors and Beyond

Advanced Materials, Volume 37, Issue 15, April 16, 2025.
Colored radiative cooling (CRC) has become a prevailing technology for achieving colorful appearance and simultaneously enhancing the effective solar reflectance of cooling coatings. This review presents recent advancements in CRC and its profound impact on energy savings in real‐world applications.

Metal‐Organic Frameworks as a Thermal Emitter for High‐Performance Passive Radiative Cooling

Small Methods, Volume 9, Issue 3, March 20, 2025.
This study explores the optical characteristics of five metal‐organic frameworks (MOFs)—ZIF‐67(Co), MOF‐74(Ni), HKUST‐1(Cu), MOF‐801(Zr), and UiO‐66(Zr)—for radiative cooling. Key factors influencing cooling efficacy are largely optical bandgaps and functional groups.

Spectral Extension of the CPF‐Measured Earth‐Reflected Solar Radiances for CPF‐CERES Intercalibration

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 4, 28 February 2025.
Abstract The Climate Absolute Radiance and Refractivity Observatory (CLARREO) Pathfinder (CPF) mission is set to launch an SI‐traceable reflective solar (RS) spectrometer aboard the International Space Station to measure Earth‐reflected solar radiation with a radiometric uncertainty of 0.3%–0.6% (k = 1).

Extended detailed balance modeling toward solar cells with cement‐based radiative coolers

Progress in Photovoltaics: Research and Applications, Volume 33, Issue 1, Page 54-63, January 2025.
This work extends the detailed‐balance model commonly used to assess radiative coolers for solar cells by incorporating the impact of Auger and Shockley–Read–Hall nonradiative recombination and of a thermal contact resistance at the cell/cooler interface.
