The diffusion coefficient of hydrogen in crystalline silicon, obtained from recent profiling experiments such as nuclear resonance retention and secondary-ion mass spectroscopy, is 3–9 orders of magnitude smaller than the previously accepted value measured by Van Wieringen and Warmoltz in 1956. Here ...
The monoisotopic mass of an ion or molecule is defined as an exact mass and is determined by summing each mass of the most abundant isotope (e.g. 1H=1.00782, 12C=12.00000, 16O=15.99491, 14N=14.00307) present in the chemical formula. ...
On the basis of this evidence Laidler 2 suggested extremely stable electronic configurations for the stable states of the OH − ion which would be strongly repulsive to an approaching hydrogen atom. The hydrogen would thus play no part in the electronic excitation....
The first step to finding the molar mass of Hydrogen Phosphonate Ion is to count the number of each atom present in a single molecule using the chemical formula, H2O3P: ElementNumber of Atoms H (Hydrogen) 2 O (Oxygen) 3 P (Phosphorus) 1 2. Find Atomic Mass of Each Element Next, usin...
Just as a dozen eggs is a way of referring to exactly 12 eggs, a gram-mole (mol) of hydrogen atoms is a way of referring to exactly 6.02214076 × 1023 hydrogen atoms (and a kmol of hydrogen atoms contains 6.02214076 × 1026 hydrogen atoms). Similarly, a mole of people would contain ...
Atmospheric hydrodynamic escape sculpts the population of low-mass close-in planets. However, distinguishing between the driving mechanisms responsible for the hydrodynamic escape of hydrogen-rich atmospheres is a complex task due to the involvement of many physical factors. Using simulations, I show th...

Hydrogen-deuterium exchange mass spectrometry (HDX-MS) provides information about the solvent accessibility and exchange kinetics of hydrogen atoms in a protein or protein complex. From:Progress in Medicinal Chemistry,2023 Also in subject areas: ...
To further investigate organic aerosol ageing mechanisms, variability of hydrogen to carbon (H:C) and oxygen to carbon (O:C) ratios are shown as a Van Krevelen diagram in Fig. 5A. We observe a clear anti-correlation between the O:C and H:C ratios for all of April within Arctic air-...
