By optimizing the pore
size distribution, it would be possible to increase the diffused reflectance of the polymer film.
Many of them liked the areas that had a lot of pores
with smaller (30-90 micron) diameter, while others preferred being around large (more than 150 micron) pores
Patented* Oat Extract -- help exfoliate the skin's surface area to unclog pores
and smooth away roughness.
may be more prominent on the nose, cheeks and chin where one has most oil glands.
The kit claims to reduces pore
appearance by 25% after just one use.
The effects of fly ash and other mineral admixtures on porosity and pore
structure of blended cement paste, with for example fly ash or slag, is well documented in the literature (Wee et al.
Particulate OM chiefly resides in large pores
that are air-filled at lower moisture content and, consequently, do not contribute substantially to soil C mineralisation (Thomsen et al.
Considering a cubic sample pocket of cement paste, two types of capillary pores
can be distinguished.
Infiltration system and cutoff system performance, probability crack occurrence in core and even effects of earth quacks on dam stability can be realized by water pore
Change in porosity will effect the drug release kinetics as bigger pores
will have fast kinetics as the mechanism involves is dissolution whereas the smaller pores
involves dissolution and diffusion together.
During adsorption, the pores
with the diameter larger than the diameter of the nitrogen molecules are accessible to the penetrating nitrogen vapor regardless of the connectedness and arrangement of the pores
Researchers have now developed a new polymer with hourglass-shaped pores
that can do the job more efficiently than standard polymers do.
According to Eberl (2002), application of a mixture of zeolite and urea fertiliser to soil resulted in less nitrate leaching by different mechanisms such as: (i) placement of urea in pores
of zeolite crystals, (ii) decrease in transformation of urea to nitrate by nitrification, and (iii) decrease in the nitrification process by ammonium adsorption on zeolite.
In this process, mercury, which is normally nonwetting, is forced into the pores
of the sample under pressure.
open up in order to take in carbon dioxide, from which plants make carbohydrate, the energy source that sustains them.
