Sentence examples for hydrogen equilibrium from inspiring English sources
This is owing to a lower hydrogen equilibrium pressure for absorption, faster absorption kinetics, lower thermal mass, and a higher thermal conductivity of uranium compared to ZrCo.
Recently, a new family of PuNi3-type structure has attracted attention as an electrode material for Ni/MH battery because of their high hydrogen storage capacity and moderate hydrogen equilibrium pressure [7].
Adsorption renders the H H stretching mode infrared active, at 4078 cm−1; and simultaneous measurement of IR absorbance and hydrogen equilibrium pressure, over a range of temperature, allowed standard adsorption enthalpy and entropy to be determined.
A good hydrogen storage electrode material must have the following properties [14, 15]: (1) catalyst for hydrogen atom, (2) corrosion resistance, (3) reversible hydrogen storage capacity, (4) good operation in a wide range of temperatures, (5) suitable hydrogen equilibrium pressure and (6) low cost.
After careful alloy design of ZrMn2-based hydrogen storage alloys through changing their stoichiometry while substituting or adding some alloying elements, the Zr(Mn0.2V0.2Ni0.6 1.8 alloy reveals relatively good properties with regard to hydrogen storage capacity, hydrogen equilibrium pressure and electrochemical discharge capacity.
It is clearly seen that when the quantity of hydrogen which diffuses through the iron membrane is important, the imposition of a potential higher than the hydrogen equilibrium potential at the detection side is not a sufficient condition to ensure the complete oxidation of hydrogen atoms.
At potentials lower than the hydrogen electrode equilibrium potential, H-adatom configurations involving subsurface Pt atoms can also be formed.
The repeated formation and cleavage of the C H bonds of methane precursors through the reversible methanogenic pathway lead to hydrogen isotope equilibrium between the precursor and intracellular water.
The hydrogen isotope equilibrium at methanogenic temperatures of our culture (0.775 0.809 at 25 °C – 60 °C: Horibe and Craig 1995) does not account for the ( {upalpha^{mathrm{H}}}_{{mathrm{CH}}_4hbox {mathrm{H}}_2mathrm{O}} ) values observed (Fig. 4b).
Progressively lower post-breakdown local cathodic current density values are observed with increasing alkalinity, as a consequence of the pH dependence of the hydrogen evolution equilibrium potential.
It allows to quantitatively describe kinetic behaviors of the electrode at various applied current densities and to estimate the diffusion coefficient for hydrogen and equilibrium content of H in the solid solution domain of hydrogen in La2MgNi9.
