It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope N-15 (Nitrogen, atomic number Z = 7, mass number A = 15).Atomic Mass and Nuclear Binding Energy for N-34 (...
To find the percent abundance of the two isotopes of nitrogen (Nitrogen-14 and Nitrogen-15) given their atomic masses and the average atomic mass of nitrogen, we can follow these steps:1. Define Variables: Let the percent ab
mass- the property of a body that causes it to have weight in a gravitational field combining weight,eq,equivalent weight,equivalent- the atomic weight of an element that has the same combining capacity as a given weight of another element; the standard is 8 for oxygen ...
According to the International Critical Tables [2], the composition of air is 20.99% oxygen, 78.03% nitrogen, 0.94% argon, and 0.03% carbon dioxide; small amounts of hydrogen, helium, neon, krypton, and xenon make up the remaining 0.01%. For most purposes, all inerts are lumped together ...

Hence, nitrogen doping of the graphene provides sites for Co incorporation. HER activity evaluation The HER catalytic activity of the Co-NG was evaluated using a standard three-electrode electrochemical cell. The catalyst mass loading on a glassy carbon electrode was 285 μg cm−2. Figure ...
The GNRs showed exceptional sensitivity for the detection of nitrogen dioxide (NO2). There are also many research results on machining of graphene using He ion beams to fabricate nanoribbon-based graphene mono-or multiple layers [34-36]. Figure 15. Comparison of simulation result for machining ...

Because of ease of operation and a power requirement lower than that for other support gases such as air, nitrogen, oxygen, and hydrogen, most laboratory ICP discharges are sustained in pure argon. This relative ease of operation and reduced power requirement are partly attributed to lower ...
Various strategies including heteroatoms doping12,13, carbon or nitrogen defect constructing14,15 and chemical functionalization16 have been proposed to optimize the electronic structure of g-C3N4 to acquire ferromagnetism. For instance, fabrication of N defects on g-C3N4 nanosheets can facilitate the ...
