Pore Structure in Food

open access: yes, 2013
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.

The Effect of Pore Structure on the Distribution of Wet Gases in Coal Seams of Enhong Syncline, SW China

open access: yesEnergies, 2022
The origin of the high content of wet gases in coalbed seams is very important geologically, especially in the Enhong syncline in China. The present study focuses on the role of the material that generates the hydrocarbons.

Structure and Composition of the Fusion Pore [PDF]

open access: yesBiophysical Journal, 2003
Earlier studies using atomic force microscopy (AFM) demonstrated the presence of fusion pores at the cell plasma membrane in a number of live secretory cells, revealing their morphology and dynamics at nm resolution and in real time. Fusion pores were stable structures at the cell plasma membrane where secretory vesicles dock and fuse to release ...

Structural details of dictyosomal pores [PDF]

open access: yesJournal of Ultrastructure Research, 1972
Structural details of the dictyosomal pores in several plant cell types are described from tangential and cross sections of Golgi cisternae. Frequency distributions of the sizes of such Golgi pores are given and compared with the corresponding values of nuclear pores in the same cells.

Structural insights into Clostridium perfringens delta toxin pore formation [PDF]

open access: yes, 2013
Clostridium perfringens Delta toxin is one of the three hemolysin-like proteins produced by C. perfringens type C and possibly type B strains. One of the others, NetB, has been shown to be the major cause of Avian Nectrotic Enteritis, which following the

Synchrotron radiation facility-based quantitative evaluation of pore structure heterogeneity and anisotropy in coal

open access: yesPetroleum Exploration and Development, 2019
In order to quantify coal pore structure heterogeneity and anisotropy, synchrotron radiation SAXS (Small Angle X-ray Scattering) was applied to obtain the SAXS images of two different rank coal samples. The surface fractal dimension (D1) and pore fractal

The Structure of a Melittin-Stabilized Pore [PDF]

open access: yesBiophysical Journal, 2015
Melittin has been reported to form toroidal pores under certain conditions, but the atomic-resolution structure of these pores is unknown. A 9-μs all-atom molecular-dynamics simulation starting from a closely packed transmembrane melittin tetramer in DMPC shows formation of a toroidal pore after 1 μs.
