In-situ characterization of capillary pressure during three-phase flow in porous media [PDF]

open access: yesE3S Web of Conferences, 2023
We characterize the pore-scale fluid distributions, phase connectivity, and local capillary pressures during three-phase flow in a water-wet Berea sandstone sample.

Numerical modeling of combustion of low-calorific-producer-gas from Mangium wood within a late mixing porous burner (LMPB) [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2017
This article presents a numerical study of combustion of low-calorific-producer-gas from Mangium wood within a late mixing porous burner (LMPB). The LMPB consists of four main components, i.e., the fuel preheating porous (FP), the porous combustor (PC),

Porous Medium [PDF]

open access: yes, 2022
A porous medium can be defined as a material which contains spaces which, when continuous in some way, enable the movement of fluids, air and materials of different chemical and physical properties. The ability of a porous medium to permit the movement of fluids, air or a mixture of different fluids is related to porosity and the variability of pore ...

Biomimetic Silica Microspheres in Biosensing

open access: yesMolecules, 2010
Lipid vesicles spontaneously fuse and assemble into a lipid bilayer on planar or spherical silica surfaces and other substrates. The supported lipid bilayers (SLBs) maintain characteristics of biological membranes, and are thus considered to be ...
