Sentence examples for hydrogen decrease from inspiring English sources
These factors improve kinetics and surface activation to absorb or desorb hydrogen, decrease the activation energy, reduce the temperature of desorption, and improve kinetics and hydrogen diffusion in the material.
Hydrogen production from less costly renewable sugars can provide affordable hydrogen, decrease reliance on fossil fuels, and achieve nearly zero net greenhouse gas emissions, but current chemical and biological means suffer from low hydrogen yields and/or severe reaction conditions.
The results reveal that 0.1 mol.% air impurities in hydrogen decrease the initial absorption rate but preserve no significant effect on the hydrogen storage capacity of the experimental alloy at 25 °C. 1 mol.% air impurities evidently deteriorate the hydrogen absorption ability of alloy at temperature below 180 °C and the poisoning effect declines with the increase of temperature.
Hydrogen production from inexpensive abundant renewable biomass can produce cheaper hydrogen, decrease reliance on fossil fuels, and achieve zero net greenhouse gas emissions, but current chemical and biological means suffer from low hydrogen yields and/or severe reaction conditions.
Preliminary evidence indicates that the ratio of the abundance of the heavier elements among the detected gases to hydrogen decreases outward from the centre of the Galaxy, a tendency that has been observed in other spiral galaxies.
In air atmosphere, hydrogen decreased and oxygen absorption increased.
However, the cell performance decreases dramatically as the partial pressure of hydrogen decreases to 0.5 atm.
The predicted permeability of hydrogen decreases, as Al or Ni concentration increases in the alloys.
It is suggested that hydrogen decreased the interfacial energy of the carbide.
The influence of hydrogen decreased with increasing nickel content, which is consistent with tensile test results.
The reasons why hydrogen decreases the stability of the passive film were discussed.
