The composition of the atmosphere has changed over time ... Respiration is the chemical process that occurs inside cells to release energy from glucose when it reacts with oxygen.

the composition of icy grains in molecular clouds, and the effects of atmospheric conditions on corrosion processes. These studies not only enhance our knowledge of the chemical makeup of ...

Despite accounting for approximately half of habitable land use, the atmospheric chemistry of agricultural regions is understudied. To investigate NPF and growth, we deploy state-of-the-art mass ...

The atmospheric sciences naturally include the study of the composition of earth’s atmosphere and the transformation of chemical compounds in the atmosphere. The gaseous, liquid, and solid phases ...

Aa Aa Aa What is the source and composition of the aerosols? Atmospheric aerosols are suspensions of liquid, solid, or mixed particles with highly variable chemical composition and size ...

We will extract ancient, fossilized micrometeorites and analyse their chemical and isotopic composition. These data will be fed into atmospheric entry numerical models. We will analyse their textures, ...
