Pore Size and Pore-Size Distribution in Microfiltration Membranes

Separation Science and Technology, 1991
Abstract This paper deals with the characterization of microfiltration membranes by porosimetric measurements. Different methods have been used to test the membranes: the Poiseuille-Knudsen method, the mercury intrusion method, and liquid displacement porometry. Membranes were also examined with the aid of a scanning electron microscope.

Re-sizing of nuclear pores

Nature Reviews Molecular Cell Biology, 2021
Zimmerli and Allegretti et al. show, in fission yeast, that nuclear pores constrict under energy deprivation or osmotic stress, which is linked to a reduction in nuclear membrane tension.

Pore size NMR imaging

Magnetic Resonance Imaging, 1998
Magnetic resonance imaging (MRI) experiments with industrial or civil engineering materials do not in general aim at determining more than water density distribution or profile. Nevertheless, it is fundamental to know more about their internal structure in relation to their macroscopic behaviour. Two techniques make possible such studies.

Pore size and pore-size distribution control of porous silica

Sensors and Actuators B: Chemical, 1995
Abstract Porous silica is a unique matrix material for chemical sensors. In this paper, porous silica is prepared via the sol-gel technique. The porosity, pore size, pore shape and pore-size distribution can be controlled by catalysts and preparation conditions. A porosity as high as 60−70% can be reached. The pore size can be controlled in the range

Size Selectivity of Narrow Pores

Physical Review Letters, 2000
The selectivity of micropores and ion channels is examined for simple pore topologies within the framework of density functional theory of highly confined fluids. In an infinite cylindrical pore purely steric (excluded volume) effects are shown to lead to strong, nontrivial size selectivity, which is highly sensitive to the pore radius.

Pore Sizes in Hydrated Dextran Microspheres

Biomacromolecules, 2000
The average pore size of hydrated dextran microspheres is derived from rheological and protein release data. The microspheres were prepared by cross-linking an aqueous solution of methacrylated dextran emulsified in a continuous poly(ethylene glycol) phase.
