A pore in a catalytic material whose diameter is less than 2 nanometers.
(geology)
A pore small enough to hold water against the pull of gravity and to retard water flow.

The researchers are trying a novel approach and creating tissue building blocks with micropores.
Figure 5 shows that the porosity of macropores and micropores does not change much.
As major cements and fillings of sandstone, when these components dissolve, micropores generate and primary pores expand.
In this work, we reported a facile method to synthesis microporous activated carbon with large quantities of narrow micropores (~0.50 nm).
Especially, the micropores contain large amount of worm-shaped graphene stacking layers with the lateral distance close to the size of hydrated electrolyte ions, which greatly benefit the capacitive performance.
Attributed to the lower limitation of 6 nm for AutoPore IV 9310, a modified Hodot classification was used as follows: micropores (6~10nm), transitional pores (10~100nm), mesopores (100~1000 nm), and macropores (1000~10,000 nm).
With the increase in filtration velocity, the deposited particle into the micropores of ceramic piece in unit time is increased, which led to rapidly completing the deep bed and transient filtration stage under high filtration velocity condition.
The expansion stress originated from inner surface of micropores of carbonaceous carbon was thought to be one of the main driving forces of deconsolidation.
This indicated wider micropores. An obvious capillary condensation step (hysteresis loop) at p/p0 > 0.4 indicated that a considerable amount of mesoporous was also present.
Very few micropores can be observed, while tortuosity of the micropores is clearly visible.
To solve this problem, carbon dioxide adsorption at 273 K is a preferred choice [12] because the higher adsorption temperature of C[O.sub.2] enables the adsorptive molecules to enter more quickly into the narrow micropores of the char.
