Elemental nitrogen can be used as an inert atmosphere for reactions requiring the exclusion of oxygen and moisture. In theliquid state, nitrogen has valuable cryogenic applications; except for the gaseshydrogen, methane,carbon monoxide,fluorine, and oxygen, practically all chemical substances have neglig...
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 O-17 (Oxygen, atomic number Z = 8, mass number A = 17). Landolt-Brnstein Homepage Introduction Index...
The mole is related to the mass of an element in the following way: one mole of carbon-12 atoms has 6.02214076 × 1023 atoms and a mass of 12 grams. In comparison, one mole of oxygen consists, by definition, of the same number of atoms as carbon-12, but it has a mass of 15.999...

Apart from the fact that the term mass should have been used instead of weight, this definition does not specify which oxygen isotope, and implies the average mass of an oxygen atom in the mixture of 16 O, 17 O, and 18 O existing in nature. The relative abundances of these three ...

The size and number of nanoparticles as a function of time (red and blue successively) are represented in Fig. 1c. During the first growth stage, the number of particles gradually increases and reaches a maximum at t ~ 180 s, after which, suddenly, the number of particles drops ...
Afterwards, unwanted graphene is removed using oxygen (O) reactive ion etching (RIE) to fabricate a defined channel. Finally, the whole device was loaded into a helium ion beam lithography (HIBL) machine to create the desired graphene nanoribbon (GNR) patterns. The GNRs showed exceptional ...
Depending on where you are in the universe, some are more prevalent. Here on Earth, elements like oxygen (O) and hydrogen (H) are common, but technetium (Tc) and nihonium (Nh) are rare. Is there an element 119? As of this writing, scientists have not isolated a stable element 119....
