porous matrix

The gold is absorbed into the porous matrix of the carbon.

In both cases, the gel forms a solid, yet porous matrix.

Darcy's law for the flow of fluid through the porous matrix.

The principle is that smaller molecules have to traverse a larger volume in a porous matrix.

Subsequent curing and pyrolysis yield a highly porous matrix, which is undesirable for most applications.

When the hydromel has solidified, the spheres are dissolved using a solvent called tetrahydrofurane, leaving a porous matrix.

Several different porous matrices have been studied and, in some cases, a very simple model of the pore structure predicts behaviour close to that observed experimentally.

When the external pressure is suddenly released, the cell structure is forcibly expanded by the entrapped steam into an open porous matrix.

AffiniTip micro-columns are modified pipette tips containing 8-10ug of streptavidin covalently bound to a porous matrix.

Finally, all the experiments indicated that the plugging effect (cancellation of the flowrate) happened after nearly 20 hours of surfactant infiltration through the porous matrix.

Description of Research Biofilms are a collection of bacterial colonies enclosed within a self-produced, porous matrix of polysaccharides.

The two electrodes are separated by a porous matrix saturated with an aqueous alkaline solution, such as potassium hydroxide (KOH).

Solvent Impregnated Resins (SIRs) are porous resin particles, which contain an additional liquid extractant inside the porous matrix.

Beneath their feet was a porous matrix that seemed at least half-alive, that absorbed anything organic and dead and moved rubbish to collector outlets with a disturbing peristaltic motion.

I still say we've got as much water coming through the porous matrix as through fractures, which means the tensile strength of the crater wall should be more than ten on the Hutchinson scale.

One of the most common methods is to embed the active ingredient in an insoluble porous matrix, such that the dissolving drug must make its way out of the matrix before it can be absorbed.

In this approach, the particles are either contacted with a precalculated amount of extractant, which completely soaks into the porous matrix, or the particles are contacted with an excess of extractant.

A porous matrix of reticulated vitreous carbon (RVC) was used to study the porosity – stirring speed coupling (PSSC) effect on the phenol hydrogenation to form cyclohexanone and cyclohexanol.

Samples inside porous matrices can also be analyzed by the ESTASI MS. During gel electrophoresis, peptides or proteins can be fractionated into different bands inside a gel.

The film resistance and capacitance, determined by equivalent circuit fitting in the absence of dissolved chlorine, were used to calculate the expected impedance response of the oxide film, based on a model of an activation-controlled surface redox reaction occurring in a porous matrix.

The interactions between the fluids are neglected, so this model assumes that the solid porous media and the other fluids form a new porous matrix through which a phase can flow, implying that the fluid-fluid interfaces remain static in steady-state flow, which is not true, but this approximation has proven useful anyway.
