Two polymers and two solvents were used in these experiments to prepare a series of nonaqueous
and aqueous solutions.
Walker began his industrial career in 1982 with the Pioneering Research Group at Rohm and Haas, where he developed a number of novel polymer-related products, including nonaqueous
colloidal dispersions for coatings-related applications, block copolymers for stabilization of colloidal dispersions, and a series of room temperature stable non-basic epoxy curing agents that thermally rearrange to generate amines.
Chapters also cover hydrotropy, phase equilibria, rheology, thickeners, nonaqueous
surfactant systems, light- and heavy-duty detergents, hand soap and body wash, fabric softeners, and household surface cleaners.
capillary electrophoretic separation of polyphenolic compounds in wine using coated capillaries at high pH in methanol.

According to Craig Taylor, the principal investigator on a new photoresist removal technology at Los Alamos National Laboratory, the industry currently uses one of three general categories of photoresist removal technologies: aqueous-based acidic or alkaline solutions, nonaqueous
organic solvents (usually containing some fraction of halogenated or polycyclic aromatic hydrocarbons), or radio-frequency plasmas of reactive species such as oxygen or fluorine.
rinse bath of 10/90 tetrahydrofuran (THF)/ethanol was used, with mild agitation.
Future plans include continuation of these studies, extension to studies in nonaqueous
solvents and at high pressure, and initiation of selected photoredox studies, some of interest as potential solar energy storage or conversion systems.

Soil and groundwater contamination; nonaqueous
phase liquids, principles and observations.
The same laws govern CE separations in aqueous and nonaqueous
media; therefore water and the organic solvents can be treated equally.
