Capillary geochemistry in non-saturated zone of soils. Water content and geochemical signatures

The unsaturated zone (UZ) retains aqueous solutions against gravity by capillary forces. This suction state corresponds to a decreasing internal pressure of the water, which modifies its thermodynamic properties. Accordingly, the speciation of solutes and the solubility of solids and gases in such capillary solutions change. The volumetric capillary water content of the soil at high suction can...

Flow Behavior of Wheat Flour - Water Dough Using a Capillary Rheometer . I . Effect of Capillary Geometry

Cereal Chem. 70(l):59-63 A capillary extrusion rheometer was employed for detailed investigation coefficient of 2,395 Pa-sec 03 4 . The flow curves, corrected for end effects of the flow behavior of wheat flour-water dough. Dough was extruded and for effect of die diameter on shear rates, were independent of capillary at ambient conditions through capillaries of different lengths and diamdimens...

Portable capillary-based (non-chip) capillary electrophoresis

Miniaturized, portable instrumentation has been gaining popularity in all areas of analytical chemistry. Capillary electrophoresis (CE), due to its main strengths of high separation efficiency, relatively short analysis time and low consumption of chemicals, is a particularly suitable technique for use in portable analytical instrumentation. In line with the general trend in miniaturization in ...

Steam-Water Capillary Pressure

Steam-water capillary pressure is of central importance in geothermal reservoir engineering, however it is still poorly known due to the difficulty making direct measurements. To this end, we have conducted experimental and theoretical studies over the past five years and have made significant progress in understanding fundamental steamwater flow. In this paper, we summarize and discuss the res...

Contactless conductivity detector for microchip capillary electrophoresis.

A microfabricated electrophoresis chip with an integrated contactless conductivity detection system is described. The new contactless conductivity microchip detector is based on placing two planar sensing aluminum film electrodes on the outer side of a poly(methyl methacrylate) (PMMA) microchip (without contacting the solution) and measuring the impedance of the solution in the separation chann...
