Ion density deviations in semipermeable ionic microcapsules.

High Cell Density Cultivation of Human Leukemia T Cells ( Jurkat Cells ) in Semipermeable Polyelectrolyte Microcapsules

Computation of the electrical double layer properties of semipermeable membranes in multicomponent electrolytes

A methodology is presented for calculating of the surface potential, Donnan potential, and ion concentration profiles for semipermeable microbial membranes that is valid for an arbitrary electrolyte composition. This model for surface potential, Donnan potential, and charge density was applied to recently reported experimental data for gram-positive bacteria, including Bacillus brevis, Rhodococ...

The Influence of 1-Butanol and Trisodium Citrate Ion on Morphology and Chemical Properties of Chitosan-Based Microcapsules during Rigidification by Alkali Treatment

Linseed oil which has various biomedical applications was encapsulated by chitosan (Chi)-based microcapsules in the development of a suitable carrier. Oil droplets formed in oil-in-water emulsion using sodium dodecyl sulfate (SDS) as emulsifier was stabilized by Chi, and microcapsules with multilayers were formed by alternate additions of SDS and Chi solutions in an emulsion through electrostat...

Improvement of ionic conductivity of gadolinium doped ceria electrolyte with nano CuO sintering aid

Gadanium doped cerium oxide ceramic (GDC) is widely used as solid electrolytes in solid oxide fuel cells because of its high oxygen ion conductivity. In this study, the effect of addition of nano CuO as a sintering aid on the properties of GDC electrolyte were investigated. For this purpose, 0.2, 0.5, and 1% mole of nano Cuo was added to GDC ceramics, which was synthesized by the solid-state me...

Fabrication of diverse microcapsule arrays of high density and good stability.

Microcapsule arrays attract a lot of interest due to their potential applications in sensing technology. A strategy for fabricating diverse microcapsule arrays through covalent linking is reported here. The self-assembly of microcapsules was directed by using a poly(allylamine hydrochloride) (PAH)-patterned template, which was created via microcontact printing. The microcapsules with PAH as the...
