New advancements in satellite technology are transforming how we understand the role oceans play in regulating carbon dioxide ...

The NASA/ESA Cassini-Huygens mission explored Saturn and its moons from 2004 to 2017, providing the most detailed images and ...

By Muhammad OsamaReviewed by Frances BriggsJun 26 2025 Researchers have discovered that the primary cause of surface wrinkling in plasma-oxidized PDMS films is water vapor absorption, not thermal ...

In this work we investigate the degenerate two-photon absorption spectrum of all-trans retinal in ethanol employing the Z-scan technique with femtosecond pulses. The two-photon absorption (2PA) ...

At any given time, about two-thirds of Earth's surface is covered by clouds. Overall, they make the planet much cooler than ...

Results of atmospheric absorption measurements made over very long slant paths at frequencies of 15 and 35 GHz are reported. The absorption was determined from a set of measurements using the Sun as a ...

The individual absorption spectra of the two NH tautomers of 10- (4,6-dichloropyrimidin-5-yl)-5,15-dimesitylcorrole are assigned on the basis of the Gouterman four-orbital model and a quantum chemical ...

Synthetic aperture radar (SAR) is a well-known imaging technique and most commonly used up to the microwave frequency spectrum (below 30 GHz) which provides spatial resolution in the sub-m range. To ...
