Competitive solvation effects in polyelectrolyte solutions

August 1, 2018
Author(s)
Alexandros Chremos, Jack F. Douglas
… of the competitive association of water (“hydration”) and ion association to the polymer backbone and the consequences … due to the high polarizability of this diffuse counter-ion cloud. We investigate the influence of counter-ion affinity for polyelectrolyte segments on the …

A Reference Tristimulus Colorimeter

June 25, 2001
Author(s)
George P. Eppeldauer
The accuracy of tristimulus colorimeters can be increased by using detector standards instead of traditional lamp standards for calibration. After high accuracy absolute spectral response determination of the color channels, spectral and amplitude

Improved Accuracy Tristimulus Colorimeters Calibrated With Standard

August 6, 1999
Author(s)
George P. Eppeldauer
A new method has been developed to calibrate tristimulus colorimeters for high accuracy color measurements. Instead of traditional lamp standards, modern, high accuracy detector standards are suggested for calibration. After high accuracy absolute spectral
