Liquid nitrogen (LN2) is typically supplied in bulk tanks, dewars, or vessels by gas companies. However, relying on ...

Although nitrogen is very abundant in the atmosphere as dinitrogen gas (N 2), it is largely inaccessible in this form to most organisms, making nitrogen a scarce resource and often limiting ...

Nitrogen oxides (NOx) are released mainly as a product of combustion processes, when oxygen (O2) and nitrogen (N2) in the air react with each other. These combustion processes take place predominantly ...

Breakthrough in N2 activation! This study unveils an electron catalysis strategy that directly converts N2 into azo compounds under mild conditions—a game-changer for nitrogen fixation. By harnessing ...

Nitrogen makes up about 78% of the Earth's atmosphere. Liquid nitrogen is very cold, so it is often used to freeze food. The boiling point of nitrogen is −196 °C, so liquid nitrogen is very ...

Gehringer explains, "Nitrogen gas is a mixture of the light atom 14 N and the heavier atom 15 N. When modern microbes use nitrogen in their metabolism, they use these two isotopes in a certain ...
