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
(2013-09-26)
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
(2007)
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
(2006-04-01)
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 ...
