Geochemistry

, 2021
Geochemistry is a branch of geological sciences that deals with chemistry rocks and minerals in various igneous, metamorphic and sedimentary processes, from high to low temperatures and in various environments. Geochemistry is also an important background for a detailed description of rocks' origin and evolution.

Underrated primary biogenic origin and lifetime of atmospheric formic and acetic acid

Scientific Reports, 2021
Formic and acetic acids are ubiquitous in the troposphere, playing an important role in the atmospheric chemistry. Recent model studies ended up with substantial low bias on their tropospheric budgets presumably due to a large missing biogenic source ...
