Nanotubes for charge storage - Towards an atomistic model
(Pergamon-Elsevier Science Ltd, 2015-04)
We examine the insertion of alkali and halide ions into narrow nanotubes of graphite and gold by density functional theory (DFT). For tubes with diameters less than about 10 Åthe optimum position of the ion is in the center ...
Optimizing feature selection through binary charged system search
Feature selection aims to find the most important information from a given set of features. As this task can be seen as an optimization problem, the combinatorial growth of the possible solutions may be inviable for a ...
An indirect method to measure the electric charge deposited on insulators during PIXE analysis
Total charge deposited by a proton beam in an insulator during PIXE analysis has been indirectly determined using a Mylar film coated with cobalt. Elemental concentrations in the samples, pieces of volcanic glass, were ...
Charge density alterations in human hair fibers: An investigation using electrostatic force microscopy
A new method for high-resolution analyses of hair surface charge density under ambient conditions is presented in this paper. Electrostatic force microscopy (EFM) is used here to analyze changes in surface charge density ...

EFFECT OF HUMIDITY IN ETHYL CELLULOSE (EC) THERMELECTRET
(Sociedad Chilena de Química, 2008)
Adsorption of polyelectrolytes onto oppositely charged cylindrical macroions
In this work we investigate the adsorption of polyelectrolyte chains onto uniformly charged cylindrical macroions by means of the Metropolis Monte Carlo simulations and weighted histogram analysis method. Adopting a ...
Electrostatic theory for imaging experiments on local charges in quantum Hall systems

Atenção! Mulheres trabalhando: um estudo de charges jornalísticas
(Universidade Federal de Santa MariaCentro de Ciências Naturais e Exatas, 2005-02-02)
This study seeks to analyze the feminine meanings produced in the charges, showing what teach on the masculine and the feminine. For that I analyze charges that circulate in newspapers. As theoretical referencial is used ...
