Flow through pore-size graded membrane pore network

open access: yesPhysical Review Fluids, 2023
Pore-size gradients are often used in the design of membrane filters to increase filter lifetime and ensure fuller use of the initial membrane pore volume. In this work, we impose pore-size gradients in the setting of a membrane filter with an internal network of interconnected tube-like pores. We model the flow and foulant transport through the filter

Effect of pore former (saw dust) characteristics on the properties of sub‐micron range low‐cost ceramic membranes

open access: yesInternational Journal of Ceramic Engineering & Science, 2020
This article addresses the effect of pore former (saw dust) characteristics on the properties (pore size and porosity) of low‐cost ceramic membranes. Two approaches were considered to reduce the average membrane pore size.

Fractal Analysis of Porous Alumina and Its Relationships with the Pore Structure and Mechanical Properties

open access: yesFractal and Fractional, 2022
Porous alumina was prepared by the sacrificial template approach using 30 vol.%, 50 vol.%, and 70 vol.% of carbon fibers and graphite as pore formers. In order to determine the pore size distribution, porosity, most probable pore size, and median pore ...

Characterization of hemodialysis membranes by inverse size exclusion chromatography [PDF]

open access: yes, 1995
Inverse size exclusion chromatography (i-SEC) was used to characterize three different cellulosic hollow fiber hemodialysis membranes, i.e. low-flux cuprophan and hemophan and high-flux RC-HP400A.

Pore structure and pore size change for tight sandstone treated with supercritical CO2 fluid

open access: yesEnergy Reports, 2023
The effects of ScCO2 on pore structure should be investigated in order to properly apply supercritical carbon dioxide (ScCO2) fracturing on tight sandstone. ScCO2 treatment was applied to three sets of tight sandstone samples.
