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 ...

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.

Microscopic study of pore structure
Ceramurgia International, 1976Abstract The relative merits of optical microscopic methods in study of the pore structure of some ceramic materials (mainly graphite) are discussed on the basis of comparison of the results of this method with those from other current methods, such as apparent and true density measurements and mercury high-pressure porosimetry.

Structure and Assembly of the Nuclear Pore Complex
Annual Review of Biophysics, 2019Nuclear pore complexes (NPCs) mediate nucleocytoplasmic exchange. They are exceptionally large protein complexes that fuse the inner and outer nuclear membranes to form channels across the nuclear envelope. About 30 different protein components, termed nucleoporins, assemble in multiple copies into an intricate cylindrical architecture.

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.

Pore Structure of Silica Gel [PDF]
Journal of Chemical Technology and Biotechnology, 1978 AbstractThe effect of washing on the texture of silica gel has been investigated in terms of parameters such as porosity, pore size distribution, surface area and absorption of moisture. It was observed that if silica gel (before activation) is washed with water containing dissolved ions such as Ca and Mg wider pores are formed at the expense of ...

Pore structure and spontaneous imbibition characteristics of marine and continental shales in China
American Association of Petroleum Geologists Bulletin, 2018The pore structure of shale has a significant effect on hydrocarbon migration and the long-term gas supply of shale gas wells. The present study investigates the spontaneous imbibition characteristics to evaluate the pore connectivity and wettability of ...

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.
