Capillary rise of a liquid into a deformable porous material
We examine the effects of capillarity and gravity in a model of one-dimensional imbibition of an incompressible liquid into a deformable porous material. We focus primarily on a capillary rise problem but also discuss a capillary/gravitational drainage configuration in which capillary and gravity forces act in the same direction. Models in both cases can be formulated as nonlinear free-boundary...
متن کاملDevelopment of Capillary Liquid Chromatography
Ishii’s group at Nagoya University started microcolumn liquid chromatography (μLC) more than 30 years ago [1]. His ideas have been realized in user−friendly μLC systems which are now commercially available from a number of manufacturers. In the meantime, injection valves with low dead volume, pumping systems working at low flow rates, high−resolution columns, and novel detection systems have be...
متن کاملCapillary forces during liquid nanodispensing.
We present a comprehensive study of the capillary force measured during the liquid nanodispensing of attoliter droplets with an atomic force microscope tip. Due to the presence of a nanochannel drilled at the tip apex and connected to a reservoir droplet deposited on the cantilever, we observe a large variety of force curves during the deposition process. We propose a numerical method which acc...
متن کاملCapillary behavior of binary liquid mixtures near criticality: Rise and kinetics.
In three different phase-separated binary liquid mixtures we have observed stationary capillary rises in which the meniscus curvature is inconsistent with the sign of the rise. This ‘‘inverted-meniscus’’ configuration occurs within approximately 50 mK of the mixture’s critical temperature and shows no sign of decay after much longer than the characteristic time for relaxation. We also report ex...
متن کاملVortex-assisted liquid-liquid-liquid microextraction (VALLLME) technique: A new microextraction approach for direct liquid chromatography and capillary electrophoresis analysis.
A new, rapid and sensitive microextraction technique named vortex-assisted liquid-liquid-liquid microextraction (VALLLME) is proposed. The complete extraction process involves two steps. First, a vortex-assisted liquid-liquid microextraction (VALLME) procedure was used to extract the analytes from a relatively large volume of sample (donor phase) to a small volume of organic solvent (intermedia...
