mi·cro·pore

(mī'krō-pōr),
An organelle formed by the pellicle of all stages of sporozoan protozoa of the subphylum Apicomplexa and also found in developmental stages that may lack the inner pellicle layer; it is composed of two concentric rings (in transverse section), the inner of which corresponds with an invagination of the outer pellicle membrane. Micorpores thus far observed seem to serve as feeding organelles; their role in nonfeeding developmental forms is unknown.

In microporous materials, small pore sizes allow only small molecules or ions to flow through the media.
In this work we have selected PIM-1 as this polymer is hydrophobic in nature and has high internal surface area and porosity than the conventional microporous materials like zeolites and activated carbons [15].

Mesoporous and microporous materials are potentially interesting systems for this purpose due to their high surface area, pore size, structure stability [1,2], and their characteristics of bioactivity in bone generating implants [3] and biocompatibility [4].
Micropore volume therefore appears to be the main control on gas sorption for microporous materials. The proportion of the total pore volume contributed by microporosity is thus an important parameter in evaluating the gas adsorption characteristics of a solid.
The topics include yoctoliter-sized vessels as potential biological models, analyzing the surface area properties of microporous materials, luminescent dendrimers, surface-functionalized inorganic colloidal nanocrystals in functional nanocomposite materials for microfabrication, and photochemically driven molecular devices and machines.
The 12 extended papers include such topics as the topology of microporous structures, the polysomatic aspects of certain microporous materials, microporous framework silicate minerals with rare and transition elements, the sodalite family, tunnel oxides, apatite, and micro- and mesoporous sulfide and selenide structures.

Their ZEBEDDE system, for zeolites by evolutionary de novo design, was designed for microporous materials, such as aluminosilicates and aluminophosphates, which can be used to turn methanol into simple alkenes.
It would take about 20 gallons of paint to cover a surface area comparable to that in a sugarcube-sized chunk of some newly made microporous materials. Their labyrinthine interiors could potentially serve a cozy sites for catalyzing chemical reactions or as minuscule sieves penetrable only by molecules of certain shapes and sizes.
Recently, a new class of microporous materials: metal-organic frameworks (MOFs) have emerged as tremendous potential materials for adsorption [1-3] and separation [4-6].
