The acceleration by molecular sieves works best when their pore diameter is about 0.3 nm, and it is apparently unrelated to their water absorption capability.

Therefore, for characterization, test filtrations are carried out and the pore diameter refers to the diameter of the smallest particles which could not pass through the membrane.
13.
From the cumulative pore volume, one can find the pressure and pore diameter where 50 % of the total volume has been added to give the median pore diameter.

Carbide-derived carbons can exhibit high surface area and tunable pore diameters ( from micropores to mesopores ) to maximize ion confinement, increasing pseudocapacitance by faradaic adsorption treatment.
16.
These aerogels have a very large interior surface area and can have its properties altered by changing the pore diameter and distribution along with adding nanosized alkali metals to alter its conductivity.
17.
Solids recovery is dependent on the filter media which must be selected for good permeability to promote dewatering but with pore diameter sufficiently small so that solids recovery is not greatly decreased.
18.
The typical molecular sieve used is a synthetic zeolite with a pore diameter around 0.4 nanometer ( Type 4A ) and a surface area of about 500 m 2 / g.
19.
When solidified, the fibres form a three-dimensional mesh of channels of diameter ranging from 50 nm to > 200 nm depending on the concentration of agarose used-higher concentrations yield lower average pore diameters.
20.
If the pore diameter is smaller than the mean free path of the diffusing gas molecules and the density of the gas is low, the gas molecules collide with the pore walls more frequently than with each other.
