Sentence examples for on impregnation from inspiring English sources

The change in nature of stationary phase on impregnation provides unique opportunities for realising improved separation of biosurfactants.

Rheological properties of liquid precursor and its dependence on impregnation conditions were measured by viscosimetry.

The low vacuum impregnation protocol provoked less impregnation close to the edge of the leaf than in its centre, probably accounting for an influence of the tissue structure on impregnation.

The differences of oxygen concentration on the catalyst from the previous report on impregnation Ag/Al2O3 catalyst with 2 wt.% Ag loading were discussed in detail.

Two-preparation procedures are used: (i) procedure A consisting of repetitive impregnations of the carbons with RuCl3·0.5H2O solutions, and (ii) procedure B based on impregnation of the carbons with Ru acac 3 vapour.
