Small-angle x-ray scattering has been used in an investigation of the pore structure of “sivol,” a material prepared by thermochemical treatment of chrysotile asbestos. It has been shown that sivol has a well-developed pore structure. Pore size distribution curves have been obtained, showing a maximum with a radius of gyration R=2.5–3.0 nm.

Influence of microstructure on process rates and product texture is widely accepted. Simulation of the pore structure of various food materials and numerous food processes has attracted recent attention in the food literature. Several approaches have been applied to predict transport phenomena in food materials.

Structure and Function of the ThermoTRP Channel Pore
2014Temperature-sensitive transient receptor potential (TRP) channels are structurally similar to other tetrameric cation channels, but can be potently activated by heat. Recent studies suggest that the pore-forming region directly participates in activation gating.

Dependence of texture on the pore structure is one of the most important fields of research. This is due to high sample-to-sample variations in application of mechanical tests. Tension, compression and flexure tests are the most common mechanical tests used in texture evaluation.

Pore Network and Morphological Characterization of Pore-Level Structures
SPE Canada Heavy Oil Technical Conference, 2017Abstract Due to the computational simplicity and time efficiency, pore network and morphological techniques are two practical approaches for characterization of pore-scale microstructures. The methods are quasi-static and exploit pore space spatial statistics to simulate pore invasions.

Structure and assembly of pore-forming proteins
Current Opinion in Structural Biology, 2010Pore-forming proteins (PFPs), involved in host-pathogen interactions, are produced as soluble, generally monomeric, proteins. To convert from the soluble to the transmembrane form, PFPs assemble, in the vicinity of the target membrane, into ring-like structures, which expose sufficient hydrophobicity to drive spontaneous bilayer insertion.

The structure of pores in isolated pea nuclei
Journal of Ultrastructure Research, 1967Nuclei were isolated from the apical buds and upper stems of pea seedlings. The structure of the nuclear pores was examined in sections of intact nuclei and in negatively stained preparations of disrupted nuclei. These pores resembled those described in various animal cells and consisted of 1 to 3 granules or possibly tubules, at the center, surrounded

Pore structure analysis without a pore shape model
Journal of Colloid and Interface Science, 1967Abstract All methods presently employed for pore structure analysis are based on idealized models for the pore shapes. Most investigators assume that the pores are cylindrical; some use the parallel plate pore model. The extent to which valid inferences can be drawn from the structure curves based on such idealizations is open to question.

Nuclear Pore Complex Structure in Birds
Journal of Structural Biology, 1997The nuclear envelope consists of two parallel membranes enclosing an aqueous lumen. In places there are pores in both membranes at which the two membranes are joined. Within these pores reside the nuclear pore complexes. The current structural models of the nuclear pore complex have been derived from a number of studies using different electron ...
