A new satellite-based method developed by Chinese researchers improves the accuracy of carbon dioxide (CO2) emission ...

Roughly 252 million years ago, Earth experienced its deadliest known extinction. Known as the Permian–Triassic Mass ...

The ocean serves as Earth's largest dynamic carbon sink, absorbing 400 million tons of carbon dioxide (CO₂) annually through continuous exchange with the atmosphere. Researchers at Yale have now ...

Scientists have known for decades that soaring atmospheric carbon dioxide emissions are causing changes in ocean chemistry, threatening marine life and ecosystems.

Conducting a stability check for joule balance after kilogram redefinition is crucial. This study investigates the mass measurement difference between joule balance and primary mass standard.

The significance of mass spectrometry lies in its unparalleled ability to accurately identify and quantify molecules in complex samples, providing invaluable insights into molecular structures and ...

Reversed-phase liquid chromatography (RPLC) coupled with electrospray ionization-mass spectrometry (ESI-MS) is widely used to analyze polar organic compounds in atmospheric particulate matter (PM).
