Kawasaki selected the literbike platform for its top-of-the-line Ninja H2 model, rather than continuing with the higher-displacement Ninja ZX-14 hyperbike. Cycle World's Kevin Cameron explained that the literbike class is "the center of the high-performance market", attracting the best development in racing, with the best chassis and suspension design, so it made sense for Kawasaki to create a ...
C 0 is the standard concentration (1 M) used to overcome concentration unit is the partial pressure of the hydrogen gas, in bar (1 bar = 10 5 Pa) R is the universal gas constant: 8.3144 J⋅K −1 ⋅mol −1 (rounded here to 4 decimal) T is the absolute temperature, in kelvin (at 25 °C: 298.15 K)
The ground state energy level of the electron in a hydrogen atom is −13.6 eV, [25] equivalent to an ultraviolet photon of roughly 91 nm wavelength. [26] The energy levels of hydrogen are referred to by consecutive quantum numbers , with n = 1 {\displaystyle n=1} being the ground state.
Quantum chemistry and Physics textbooks usually treat the binding of the molecule in the electronic ground state by the simplest possible ansatz for the wave function: the (normalized) sum of two 1s hydrogen wave functions centered on each nucleus. This ansatz correctly reproduces the binding but is numerically unsatisfactory.
Hydrogen can be purified by passing through a membrane composed of palladium and silver. Permeability of the former to hydrogen was discovered back in the 1860s. [2] An alloy with a ca. 3:1 ratio for Pd:Ag is more structural robust than pure Pd, which is the active component that allows the selective diffusion of H 2 through it.
Cimetidine was the prototypical histamine H 2 receptor antagonist from which later drugs were developed. Cimetidine was the culmination of a project at Smith, Kline & French (SK&F; now GlaxoSmithKline) by James W. Black, C. Robin Ganellin, and others to develop a histamine receptor antagonist that would suppress stomach acid secretion.
To make interpretation easier, only c-type ions are illustrated in the MS/MS spectrum here. However, it is possible to observe other types of fragment ions. Hydrogen–deuterium exchange mass spectrometry (HX-MS or HDX-MS) can determine the overall deuterium content of molecules which have undergone H/D exchange.
