  Pore - Wikipedia, the free encyclopedia
Enlarged pores can be a cosmetic problem, especially during puberty, where pores, especially around the nose (the "T-zone") enlarge in order to cope with increased oil output.
Pores in rock are where groundwater, oil, and natural gas are found.
Pores can also be referred to as the space between molecules, such as when salt dissolves in water, it goes in the pores of the water.

 SOFIA - OFR 97-454 - Coring and Pore Water Extraction
Pore water is obtained from a core by attaching the core barrel to a support, adding a second piston, and gradually compressing the core using threaded steel rods and threaded plates attached to the support (B).
Pore water from various depth intervals exits the core through holes in the side of the core barrel, passes through a syringe filter, and is collected in appropriate vessels (C).
Pore water began to flow from the sampling ports into the collection vessels as the steel rods from the top and bottom were alternately advanced, squeezing the peat and forcing the pore water out the sampling ports.

 Pore size, shape   (Site not responding. Last check: )
Pore size defines an ability of the analyte molecules to penetrate inside the particle and interact with its inner surface.
Pore shape is mainly unknown, but it could be approximated by the model.
Decision, which model is appropriate for particular adsorbent usually based on the cross-calculations of pore volume and surface area and comparison with the experimentally measured values.

 Silica Aerogels - Pore Structure   (Site not responding. Last check: )
The amount of gas adsorbed depends of the size of the pores within the sample and on the partial pressure of the gas relative to its saturation pressure.
If the mass, density, and total pore volume of an aerogel are measured, it is apparent that there is a substantial amount of porosity that is not accounted for.
Pores in various materials are either open or closed depending on whether the pore walls are solid or themselves porous (or at least "holey").

 Managing Soil Tilth: Texture, Structure and Pore Space   (Site not responding. Last check: )
Pore spaces are a factor of soil texture and structure.
The pore spaces in a bottle of table salt are small compared to the pore spaces between a bottle of golf balls.
On fine-texture, clayey and compacted soils, a lack of large pore spaces restricts water and air infiltration and movement thus limiting root growth and the activity of beneficial soil microorganisms.

 Biophysical Journal: Reconstituted fusion pore   (Site not responding. Last check: )
ABSTRACT Fusion pores or porosomes are basket-like structures at the cell plasma membrane, at the base of which, membrane-bound secretory vesicles dock and fuse to release vesicular contents.
Conformation that the inverted cups are fusion pores, as they appear from within the cell, was revealed from AFM studies demonstrating attached secretory vesicles, and from immunoAFM studies demonstrating the localization of t-SNARE proteins at the base of the fusion pore or porosome cup (Jena et al., 2003).
Because fusion pores or porosomes are stable structures at the cell PM, we hypothesized that if membrane-bounded secretory vesicles or zymogen granules (ZGs) were to fuse at the base of the fusion pore, it should be possible to isolate ZG-associated fusion pore complexes.
