Ion density deviations in semipermeable ionic microcapsules

Ion density deviations in semipermeable ionic microcapsules.

By implementing the nonlinear Poisson-Boltzmann theory in a cell model, we theoretically investigate the influence of polyelectrolye gel permeability on ion densities and pH deviations inside the cavities of ionic microcapsules. Our calculations show that variations in permeability of a charged capsule shell cause a redistribution of ion densities within the capsule, which ultimately affects th...

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

Ionic transport in high-energy-density matter.

Ionic transport coefficients for dense plasmas have been numerically computed using an effective Boltzmann approach. We have developed a simplified effective potential approach that yields accurate fits for all of the relevant cross sections and collision integrals. Our results have been validated with molecular-dynamics simulations for self-diffusion, interdiffusion, viscosity, and thermal con...

Swelling and shrinking of polyelectrolyte microcapsules in response to changes in temperature and ionic strength.

Swelling and shrinking of polyelectrolyte microcapsules consisting of poly(styrene sulfonate, sodium salt) (PSS) and poly(diallyldimethyl ammonium) chloride (PDADMAC) multilayers have been observed in response to temperature and electrolyte exposure, respectively. Heat-induced capsule swelling and capsule wall volume reduction were observed by confocal laser scanning microscopy (CLSM) and scann...

The Role of Security in Social Deviations

The aim of this study is to investigate the role of security in social deviations among women of Babol city. Descriptive survey research method was used and the unit of analysis is 15-29 year old women that 284 women are selected on the basis of Cochran formula and using multi-stage random cluster sampling. The results show that there is a weak significant relationship between the independent v...
