Sentence examples for blocking of pores from inspiring English sources

Physically blocking of pores and poisoning of acidic sites were observed on the P-impregnated catalysts.

The reduced SBET in Fe2O3 BC could be attributed to the blocking of pores in the biochar matrix by Fe2O3 and other metal compounds inherent in the biosorbent.

This process is promoted by the increase of porosity upon initial water loss and the blocking of pores in the course of oxidation.

The consumption of basic sites, as well as the blocking of pores, was considered as the main reason for catalyst deactivation.

However, the reusability studies demonstrated that the resin activity falls in subsequent reactions due to blocking of pores by larger products, particularly di-acylated derivatives rendering some pore networks ineffective.

For the old cementitious material, the blocking of pores by the in-situ hydrolysis and condensation of TEOS, forming silica sol/gel, as well as its quick (comparable to that of sodium silicate) pozzolanic reaction with calcium hydroxide, forming additional calcium silicate hydrate, contribute to the improved surface quality.

Consistent results have been obtained for nitrogen and carbon dioxide, and the smallest pores are shown to be reversibly closed and opened under air exposure and outgassing at 600 °C, respectively, probably due to blocking of pore entrances by surface oxides.

The sensing mechanism depends on the blocking of pore channels when the protein antigen molecules bind to antibody molecules attached to the channel walls, impeding the diffusion of redox probe, ferrocenemethanol, towards the sensing platinum wire overlaid by the nanoporous alumina film.

This may cause blocking of pore spaces alongside rapid passivation of the NPs themselves, potentially limiting the reactive area of influence surrounding an injection well.

These results were interpreted as a blocking of the pores and a non-percolating pore system for too large Nafion contents.

The results indicate that the desired membrane characteristics for this application are as follows: high permeability to water vapor, hydrophobic to the aqueous solution with high liquid entry pressure (LEP) to avoid wettability of the membrane pores and no capillary condensation of water vapor to avoid blocking of the pores.
