Nitrogen is the primary gas in the atmosphere. It makes up 78.084 percent by volume in dry air, and that makes it the most common gas in the atmosphere. Its atomic symbol is N and its atomic number is 7. The Discovery of Nitrogen ...
Nitrogen (N2) gas in the atmosphere is partially replenished by microbial denitrification of ammonia. Recent study has shown that Alcaligenes ammonioxydans oxidizes ammonia to dinitrogen via a process featuring the intermediate hydroxylamine, termed “Dirammox” (direct ammonia oxidation). However, the...
The Earth's N2-dominated atmosphere is a very special feature. Firstly, N2 as main gas is unique on the terrestrial planets in the inner solar system and gives a hint for tectonic activity. Studying the origins of atmospheric nitrogen and its stability provides insights into the uniqueness of ...
Effects of N2/H2Sintering Atmosphere on the Properties of Cu2ZnSn(S,Se)4Solar Cells Fabricated by a Nanoparticle-Based Approach N2A N2/H2 mixture gas was used for the first time to sinter Cu2ZnSn(S,Se)4 (CZTSSe) films fabricated by a nanoparticle-based approach. It was ... Yiwen,...
This research is rooted in an analysis of the gas phase composition within the furnace during the actual production of magnesite calcination. Employing the TG-DTA thermal analysis technique, the study investigates the therm...
Here we show that crustal nitrogen from the crystalline basement alone—degassing at a steady state in proportion to crustal helium-4 generation—can reach sufficient concentrations at the base of some sedimentary basins to form a free gas phase. Using a gas diffusion model coupled with sedimentary...
air inside the greenhouse. The impact of this greenhouse gas on making the Earth warmer is called the 'greenhouse effect'. Water vapor (H ₂ O), carbon dioxide (CO ₂), nitrous oxide (N ₂ O), Freon, methane (CH ₄) are the main greenhouse gases in the earth's atmosphere. ...
