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. ...

1. Count The Number of Each Atom 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 ...
Most of the work was done with argon but some measurements were made with helium and with helium-argon and argon-krypton mixtures. To clarify the role of impurities, some work was done with the addition of 1.25% hydrogen to the argon. The results confirm that the ions of the principal ...
Au@Cu2O Core鈥揝hell and Au@Cu2Se Yolk鈥揝hell Nanocrystals as Promising Photocatalysts in Photoelectrochemical Water Splitting and Photocatalytic Hydrogen... In this work, we demonstrated the practical use of Au@Cu2O core鈥搒hell and Au@Cu2Se yolk鈥搒hell nanocrystals as photocatalysts in photoelect...
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...

On the other hand, higher pH values were observed for the separation of the toxic diterpenoid alkaloids aconitine, mesaconitine, and hypaconitine on C8 and C18 stationary phases using eluents containing ammonium acetate (pH 8.9) [180] and ammonium hydrogen carbonate (pH 9.5) [181], respectively...
An easy-to-use, fast, and routine on-line deuterium exchange method was developed to exchange active hydrogens (NH, OH). This method, combined with electron impact ionization, is demonstrated and discussed in terms of the unique information available through the EI fragmentation patterns, its ...
Ionic Liquids are a promising alternative to water electrolytes for the electrodeposition of metals. These solvents have a much larger electrochemical window than water that expands the potential of electrodeposition. However, mass transport in Ionic Liq
