The influence of external currents on the potential response of polymeric membrane ion-selective electrodes (ISEs) is analyzed theoretically. The treatment is based on the well-established potential model of ISE membranes, extended by contributions from cu ...
Polyelectrolyte complex membrane formation has been studied, online, using the synthetic boundary technique of an Optima XL-I anal. ultracentrifuge. This recent method, established by the first author, has now been evaluated concerning its sensitivity to m ...
Methods are provided for producing microcapsules based on two oppositely charged polymers, in particular to optimise the permeability and mechanical stability of microcapsules. The capsules are formed by introducing liquid droplets from an aqueous solution ...
A math. model describing a novel sweeping gas membrane distn. (SGMD) configuration is presented and the sepn. of two volatile components from binary mixts. by this membrane process is theor. investigated. SGMD configuration is modified by using a thermosta ...
Methodology was developed for presenting to fish cells in culture whole-water samples without extraction and used to evaluate the toxicity to a rainbow trout gill cell line, RTgill-W1, of more than 30 whole-water samples collected from a paper mill over ap ...
This paper introduces the notion of Voronoi diagrams and Delaunay triangulations generated by the vertices of a piecewise flat, triangulated surface. Based on properties of such structures, a generalized flip algorithm to construct the Delaunay triangulati ...
Changes in sample concentrations of CO2 or organic acids cause potential instabilities when polymer membranes are directly applied to the surface of ion-selective field-effect transistors (ISFETs). Currently used designs avoid this well-documented effect b ...
A microfluidic device for random fragmentation of DNA or RNA based on the application of a hydrodynamic shear force to these biomolecules is presented. Different from conventional fragmentation instruments, the microchip-based implementation allows molecul ...
There is provided a method for plasmid DNA extraction to reproducibly yield relatively crude preparation which is suitable for transfection into mammalian cells. The inventors have determined that the high level of purification previously thought to be nec ...
