متن کاملPotentiometric Titrations as a Tool for Surface Charge Determination
This article summarizes methods for determining proton surface charge at mineral/water interfaces. It covers conventional experimental procedures and discusses problems with the techniques. Also it involves recommendations for obtaining reasonable and comparable results. The term "comparable results" refers to comparison between results for the same solid as obtained in different laboratories. ...
متن کاملSynthesis and characterization of surface-enhanced Raman-scattered gold nanoparticles
In this paper, we report a simple, rapid, and robust method to synthesize surface-enhanced Raman-scattered gold nanoparticles (GNPs) based on green chemistry. Vitis vinifera L. extract was used to synthesize noncytotoxic Raman-active GNPs. These GNPs were characterized by ultraviolet-visible spectroscopy, dynamic light-scattering, Fourier-transform infrared (FTIR), transmission electron microsc...
متن کاملSurface Approximation to Scattered Lines
A global weighted-mean approximation to scattered lines is introduced. Rational Gaussian weights are stretched along lines and standard deviations of Gaussians are selected in such a way as to produce surfaces that closely follow data along lines. When the lengths of the lines approach zero, the proposed formulation converges to that of global weighted mean approximation to scattered points. Th...
متن کاملSurface Approximation to Scattered Lines
A method for fitting a surface to line data is introduced. A weighted-mean approach to the problem is described using rational Gaussian (RaG) weights. The Gaussians are stretched along the lines and their widths are selected to reproduce sharp edges and corners in the surface. When the length of the lines becomes zero, the formulation converges to a weighted sum of points. Therefore, traditiona...
