The atmosphere is mostly nitrogen (approximately 80%) and oxygen (approximately 20%). The remaining gases are found in much smaller proportions, such as carbon dioxide and water vapour.

The observational evidence remains ambiguous. On the one hand, net carbon dioxide uptake over the entire cycle of rotation in managed forests increases substantially with nitrogen deposition. Most ...

The redox reactions affect the number of covalent bonds that a carbon makes to a heteroatom substituent, such as nitrogen and oxygen ... in loss of carbon dioxide. Nature's redox enzymes are ...

Without carbon dioxide, plants wouldn’t grow ... pressures inside a car engine or factory furnace can cause the nitrogen and oxygen in the air to react together to make oxides of nitrogen.

Flatulence is the expulsion of gases from the digestive system through the anus. Eructation or burping/belching is expulsion ...

Carbon particles are present in many aspects of our daily lives. Soot, which consists of tiny carbon particles, is generated ...

Unraveling the chemical processes in soot particle filters reveals new ways to produce synthetic fuels.

Mars has a very thin atmosphere containing mostly carbon dioxide, with nitrogen, argon, and trace amounts of oxygen and water vapor. The atmosphere also contains thin water and carbon dioxide ...

Longer, more diverse rotations of crops fertilized with livestock manure have many environmental benefits, but carbon sequestration isn't one of them, according to a new study. Longer, more ...

Nitrogen doping, in particular, has been shown to be a highly effective strategy in creating advanced materials for carbon-dioxide capture ... mainly oxygen and nitrogen groups, during nanocarbon ...

Industrial gas firms produce and distribute atmospheric gases, like oxygen and nitrogen, and process gases, like hydrogen and carbon dioxide. Those gases are consumed in a variety of markets ...

Get Instant Summarized Text (Gist) Diversified cropping systems enhance nitrogen supply but do not increase soil carbon levels. Despite increased carbon input from diverse rotations and manure ...
