Sentence examples for constant polarisation from inspiring English sources

Geobacter sulfurreducens biofilms were formed under constant polarisation at −0.6 V vs. Ag/AgCl on stainless steel cathodes to catalyse the reduction of fumarate.

Then a combinatorial approach was undertaken to simultaneously study the influence of electrolyte pressure at constant defect polarisation and of relative atmospheric humidity on the de-adhesion rate.

While this complicates the extraction of rate constants from oxygen evolution polarisation curves, it enables the study of influence of S OH and S O surface coverages on the organic oxidation rate while keeping the overall oxygen evolution kinetics constant.

A diagnostic criterion for participation of hydrogen donors other than the hydronium ions is found in the dependence of polarisation at a constant current density on pH.

Previously, the rate of organic oxidation by the S O species has been assumed to be much faster than the combination of S O to form O2, but here a model is developed without this assumption and solved numerically for a wide range of rate constants to determine steady-state polarisation curves for oxygen evolution and the rate of the oxidation of organics.

Multiple sets of rate constants describe the same steady-state polarisation curve with unique surface oxide coverage vs. potential behaviour.

To illustrate this variation, we represent a two-dimensional slice of the four-dimensional polarisation space: the pump power is held constant while two quarter waveplates are successively swept through all possible angles in 4.5 degree (0.025π rad) steps (Fig. 2).

The addition of OH− ions to NaCl solution raised the anodic dissolution rate of pure Al in value and at the same time extended the constant anodic current density region in width on the polarisation curves.

In low frequency range, the dielectric constant has a high value which can be attributed to various polarisation effects, namely ionic and dipolar.

For one and the same average current density significant reduction of polarisation was achieved under certain conditions, compared to that required by constant current.

The dielectric constant and loss factor were estimated as 390 and 0.034 at 100 kHz respectively and the remnant polarisation was 28 µC/cm2 at 19 V.
