Nitrogen fixation is the process where atmospheric nitrogen is converted into a reactive form by breaking the triple covalent bond between nitrogen atoms, allowing it to bond with other elements like carbon, hydrogen, and oxygen through the use of specialized enzymes in microorganisms or industrial pr...
The reduction of atmospheric nitrogen is a complex process that requires a large input of energy to proceed (Postgate 1982). The nitrogen molecule is composed of two nitrogen atoms joined by a triple covalent bond, thus making the molecule highly inert and nonreactive. Nitrogenase catalyzes the ...
Boron–nitrogen bondCovalent x dative bondsDative bondFunctional groupThis study consists of the theoretical analysis of some organic molecules and their inorganic similar compounds, through substitution of two carbon atoms by boron and nitrogen atoms. The methods DFT/B3-LYP/TZVPP and CC2/TZVPP ...
To study whether specific O-N ordering affects the thermo- dynamics of oxynitrides, we study 30 symmetrically distinct O-N configurations for each structure and composi- tion. We find that specific O-N configuration leads to the nitrogen-nitrogen covalent bond formation and significantly stabilizes...
For example, in complexes of boron trifluoride with ammonia 1 and nitrogen heterocycles 2 , frequencies lying in the range between 980 cm. 1 and 1,120 cm. 1 have been assigned to this motion, in the complex of boron trimethyl with ammonia, a value of 1,105 cm. 1 has been selected 3...
It forms very few compounds with other elements due to its strong triple covalent bond between the nitrogen atoms. However, given specific conditions, nitrogen can react to form various compounds, such as ammonia (NH3), nitric oxide (NO), and nitrogen dioxide (NO2). These compounds are ...
Example 3: Identifying the Product from the Reaction between Nitrogen and Oxygen The inert nature of nitrogen gas (N2) can be overcome by using powerful electric arcs to break the bonds between the two atoms. In an atmosphere of hydrogen and nitrogen, an electric arc causes ammonia gas (NH3...

But, on the other hand, it was not possible to find a clear correlation between oxidation degree and nitrogen content. Aging of cellulosic substrates is generally accepted to cause a closing of pores, reduced reactivity and “hornification”, also reflected by loss of mechanical strength and ...
