pH-dependent surface charging and points of zero charge. IV. Update and new approach.
The recently published points of zero charge (PZC) and isoelectric points (IEPs) of various materials are compiled to update the previous compilation [M. Kosmulski, Surface Charging and Points of Zero Charge, CRC Press, Boca Raton, FL, 2009]. Unlike in previous compilations by the same author [Chemical Properties of Material Surfaces, Dekker, New York, 2001; J. Colloid Interface Sci. 253 (2002)...
متن کاملAdsorption of dissolved aluminum on sapphire-c and kaolinite: implications for points of zero charge of clay minerals
We have studied the impact of dissolved aluminum on interfacial properties of two aluminum bearing minerals, corundum and kaolinite. The effect of intentionally adding dissolved aluminum on electrokinetic potential of basal plane surfaces of sapphire was studied by streaming potential measurements as a function of pH and was complemented by a second harmonic generation (SHG) study at pH 6. The ...
متن کاملCommon Zero Points of Two Finite Families of Maximal Monotone Operators via Proximal Point Algorithms
In this work, it is presented iterative schemes for achieving to common points of the solutions set of the system of generalized mixed equilibrium problems, solutions set of the variational inequality for an inverse-strongly monotone operator, common fixed points set of two infinite sequences of relatively nonexpansive mappings and common zero points set of two finite sequences of maximal monot...
متن کاملOn the Number of Nowhere Zero Points in Linear Mappings
Let A be a nonsingular n by n matrix over the finite field GFq, k = bn2 c, q = p, a ≥ 1, where p is prime. Let P (A, q) denote the number of vectors x in (GFq) such that both x and Ax have no zero component. We prove that for n ≥ 2, and q > 2 ( 2n 3 ) , P (A, q) ≥ [(q − 1)(q − 3)](q − 2)n−2k and describe all matrices A for which the equality holds. We also prove that the result conjectured in [...
متن کاملZero Weights in Weak Efficient and Inefficient Points with AHP
In this paper an approach in data envelopment analysis dealing with evaluation of non – zero slacks was propounded. This approach intends that weight of inefficient and weak efficient points that have been evaluated as zero weight, be considered as positive weight, and also in this approach, the pareto efficiency evaluates the picture of this point. In this approach positive weights in the i...
