Imaging the Pore Structure of Geomaterials
Science, 1995Laser scanning confocal microscopy can be used to image the pore structure of geologic materials in three dimensions at a resolution of 200 nanometers. The technique involves impregnation of the void space with an epoxy doped with a fluorochrome whose fluorescent wavelength matches the excitation wavelength.

Abstract A small grain of iron catalyst, used in the synthesis of ammonia, has an external surface of about 1 cm2/g, but it has an internal surface of 100,000 cm2/g. Since catalysis takes place on the surface, obviously the surface in the pores is of vital importance.

The Structure of the Nuclear Pore Complex
Annual Review of Biochemistry, 2011In eukaryotic cells, the spatial segregation of replication and transcription in the nucleus and translation in the cytoplasm imposes the requirement of transporting thousands of macromolecules between these two compartments. Nuclear pore complexes (NPCs) are the sole gateways that facilitate this macromolecular exchange across the nuclear envelope ...

Nuclear pore structure and function
Seminars in Cell Biology, 1992Nuclear pores are huge macromolecular assemblies, approximately 120 nm in diameter, that perforate the nuclear membrane and mediate nucleocytoplasmic transport. Nuclear pores are constructed from a cylindrical spoke-plug complex sandwiched between nucleoplasmic and cytoplasmic rings.

Structural analysis of mitochondrial pores
Experientia, 1990Structural information about the channel in the mitochondrial outer membrane, derived from sequence analysis and electron microscopy of two-dimensional crystals, is summarized. A model for the channel is presented, consisting of a cylindrical beta-barrel that is formed by one or two 30-kDa polypeptides, with an alpha-carbon backbone diameter of 3.8 nm.

Modeling the pore structure of coal
AIChE Journal, 1987AbstractThe predictions of the random‐pore model, and various other models formulated here, are compared with experimental data for the uptake of methane by coal. It is found that the most appropriate is a modified model considering coal to be comprised of microporous grains, with the random‐pore model holding for the micropores in the grains.

Fuel, 2015
Abstract Pore connectivity is limited in shale formations, unlike in conventional reservoirs, for which cyclic void models, such as the regular-lattice model, are often used to represent the connectivity. In the cyclic models, the random assignment of throat sizes to lattice elements leads to a plateau-like variation of a capillary pressure with ...
