Pore-like structures in biological membranes
Journal of Cell Science, 1977ABSTRACT In freeze-fracture replicas, biological membranes appear as smooth surfaces interrupted by random globular protrusions, the intramembrane particles. Smooth areas correspond to the membrane phospholipidic domain, while intramembrane particles are the morphological counterpart of membrane proteins. In the present work, examination

Evaluating Geotextile Pore Structure
1996There are many test methods available to determine the pore sizes of geotextile filters. Often overlooked is the fact that each method provides a different interpretation of a geotextile's pore structure. A survey of the available test methods, indicates that four categories of pores can be measured.

Pore Structure of Imogolite Computer Models
Langmuir, 1996This study analyzes computer models of the microporous material imogolite. The purpose of this work is to validate computational methods developed for extracting pore size, pore volume, and surface area measurement of molecular level computer models. We accomplished this by comparing model properties with experimental data derived from N2 adsorption ...

Hierarchical Pore Structures through Diatom Zeolitization
Angewandte Chemie International Edition, 2000The controlled construction of a microporous/macroporous materials from diatomaceous earth and a high silica zeolite by a simple method is reported. The picture shows scanning electron microscopy images of the material at two scales (left and center) and the arrangement of the zeolite crystals precipitated onto it (right). These materials have numerous

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 and transport processes
2023Abstract This chapter describes how the characteristics of the pore structure of cement-based materials play a fundamental role in governing the transport processes in concrete, and hence, its durability. Variations in the size of the pores in concrete and their influence on both transport properties and durability are highlighted in ...

FRAGMENTATION IN RANDOM PORE STRUCTURES
Chemical Engineering Communications, 1989The problem of fragmentation of solid phase in reacting porous structures that consist of d (d = 1,2,3) mutually perpendicular bundles of parallel, randomly overlapping cylindrical capillaries is considered. The evolution of fragmentation with the porosity is studied using a Monte Carlo stimulation procedure which rests in using the trajectories of ...

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 ...

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.
