Critical adsorption of polyelectrolytes onto planar and convex highly charged surfaces: the nonlinear Poisson-Boltzmann approach
(Iop Publishing Ltd, 2016-08-18)
We study the adsorption-desorption transition of polyelectrolyte chains onto planar, cylindrical and spherical surfaces with arbitrarily high surface charge densities by massive Monte Carlo computer simulations. We examine ...
Static dielectric constants of acetonitrile/water mixtures at different temperatures and debye-hückel A and a0B parameters for activity coefficients
(American Chemical Society, 2007-05)
Static dielectric constants of acetonitrile/water mixtures in the whole composition range and within the temperature range from (15 to 60) °C have been measured. The values were fitted to a unique equation as a simultaneous ...
Nanoscale origins of super-capacitance phenomena
(2019-02-28)
We review the origins of capacitive phenomena at the nanoscale to demonstrate that electrochemistry cannot be understood without a critical re-reading of nanoscale electronics, and vice-versa. The fundamentals are stated ...
An assessment on the use of the debye-hückel equation for the thermodynamic modeling of aqueous systems containing polymers and salts
(Brazilian Society of Chemical Engineering, 2010)
In this work, a study on the role of the long-range term of excess Gibbs energy models in the modeling of aqueous systems containing polymers and salts is presented. Four different approaches on how to account for the ...
AN ASSESSMENT ON THE USE OF THE DEBYE-HUCKEL EQUATION FOR THE THERMODYNAMIC MODELING OF AQUEOUS SYSTEMS CONTAINING POLYMERS AND SALTS
(BRAZILIAN SOC CHEMICAL ENG, 2010)
In this work, a study on the role of the long-range term of excess Gibbs energy models in the modeling of aqueous systems containing polymers and salts is presented. Four different approaches on how to account for the ...
Equilibrio de fases para sistemas etanol-agua en presencia de polialcoholes y sales
(Universidad Nacional de Colombia Sede Medellín, 2011)
Se propone un modelo termodinámico semiempírico para el equilibrio líquido-vapor del sistema etanol-agua con polialcoholes y sales. El modelo usa las ecuaciones Gibbs-Duhem y Debye-Hückel, las cuales modifican el modelo ...
Influencia de la temperatura y longitud de cadena en los coeficientes osmóticos y de actividad de sales de amonio cuaternario en solución acuosa
(2011)
Se determinaron los coeficientes osmóticos y de actividad por medidas isopiésticas de soluciones acuosas de Met3OctNBr, DecMet3NBr, DodecMet3NBr and Met3TetradecNBr a cinco temperaturas: 303.15, 298.15, 293.15, 288.15 y ...
Transiciones de fase en suspensiones coloidales asimétricas
(UniandesFísicaFacultad de CienciasDepartamento de Física, 2005)
La pregunta sobre las condiciones de posibilidad de una transición de fase en suspensiones coloidales acuosas constituye un debate, por ahora inconcluso, dentro del fecundo y rico campo de la ciencia coloidal. En efecto ...
Equilibrio de fases para sistemas etanol-agua en presencia de polialcoholes y salesPhase equilibrium for ethanol-water systems in the presence of salts and polyalcohols

Coulomb screening correction to the Q value of the triple-alpha process in thermal plasmas
(2020-09-01)
The triple-alpha reaction is key to 12C production and is expected to occur in weakly coupled thermal plasmas as encountered in normal stars.We investigate how Coulomb screening affects the structure of a system of three ...
