Abstract The objective of the present study was to characterize the physicochemical composition and to quantify the fatty acids of chocolates produced from different cocoa varieties (Theobroma cacao L ...

JWST is so powerful that it can analyse the chemical composition of the planet's atmosphere from the light that passes through from the small red Sun it orbits.

While an unknown chemical process may be the source of these molecules in K2-18b’s atmosphere, the results are the strongest evidence yet that life may exist on a planet outside our solar system.

Our results showed Earth's earliest crust - known as the protocrust - that formed during the Hadean eon, would have a chemical composition identical to that of the modern average continental crust.

Explore the fascinating evolution of Mars atmosphere. Discover how it transformed, becoming trapped in its crust's clay minerals.

Motor vehicles are major sources of gas-phase organic carbon, which includes volatile organic compounds (VOCs) and other compounds with lower vapor pressures. These emissions react in the atmosphere, ...

Changes in the structure and composition of nano-sized Ni-Cu multilayer films with increasing temperature in an atmosphere with and without hydrogen ...

The answer is no, according to new research that inferred the water content of the planet's interior - a key indicator for whether or not Venus once had oceans - based on the chemical composition ...

Apollo moon rocks reveal secrets of the moon’s thin ‘atmosphere’ A constant rain of tiny meteorites kicks up dust on the moon and helps generate the thin layer of atoms that form its exosphere.

Satellites can measure the composition of the stratosphere by pointing a sensor at the horizon and measuring which wavelengths of light are absorbed at sunrise and sunset.

The focus of this study is to examine the evolution of the injected water vapor in the stratosphere over time, altitude, and latitude in the year following the HTHH eruption, to identify a number of ...
