Because of their high mechanical, thermal and chemical stability, variable manufacturing of pore sizes with a small pore size distribution and variety of surface modifications, a wide array of applications are possible.

In these structures, scientists use the concept of capillary condensation to determine pore size distribution and surface area though adsorption isotherms . of materials are also highly dependent on bridging effects resulting from capillary condensation.
13.
The most popular aqueous phase carbons are bituminous based because of their hardness, abrasion resistance, pore size distribution, and low cost, but their effectiveness needs to be tested in each application to determine the optimal product.
14.
It is widely used to measure minimum, maximum ( or first bubble point ) and mean flow pore sizes, and pore size distribution of the through pores in membranes ultrafiltration media, hollow fibers, ceramics, etc.
15.
An effective separator must possess a number of mechanical properties; such as permeability, porosity, pore size distribution, specific surface area, mechanical design and strength, electrical resistance, ionic conductivity, and chemical compatibility with the electrolyte.
16.
It is prepared by the reaction between sodium silicate and acetic acid, which is followed by a series of after-treatment processes such as aging, pickling, etc . These after-treatment methods results in various pore size distributions.
17.
It is the most widely used adsorbent since most of its chemical ( e . g . surface groups ) and physical properties ( e . g . pore size distribution and surface area ) can be tuned according to what is needed.
18.
The pore size distribution affects the ability of plants and other organisms to access water and oxygen; large, continuous pores allow rapid transmission of air, water and dissolved nutrients through soil, and small pores store water between rainfall or irrigation events.
19.
Moreover, membranes made out of carbon nanotube arrays have been suggested as switchable molecular sieves, with sieving and permeation features that can be dynamically activated / deactivated by either pore size distribution ( passive control ) or external electrostatic fields ( active control ).
20.
At higher temperatures pseudoboehmite is transformed to ?-alumina but the pore size distribution remains unchanged up to 1000 �C . At around 1100 �C however, specific area significantly decreases because of sintering related to a transformation to ?-Al 2 O 3.
