Advanced Materials Technologies, EarlyView.This study formulated a 5Y‐PSZ zirconia paste for extrusion‐based additive manufacturing via direct ink writing, producing dense ceramic structures for dental applications. A colloidal approach with 47 vol% nanometric powder and tailored additives optimized rheology and printability.

Preparations of organobentonite using nonionic surfactants
Chemosphere, 2001Due to hydrophilic environment at its surface, natural bentonite is an ineffective sorbent for nonpolar nonionic organic compounds in water even though it has high surface area. The surface properties of natural bentonite can be greatly modified by simple ion-exchange reactions with large organic cations (cationic surfactants) and this organobentonite ...

Nonionic Fluorosilicone Surfactants
Journal of Colloid and Interface Science, 1993Abstract New fluorosilicone surfactants have been prepared. The focus has been on branched disiloxane and trisiloxane hydrophobes having 3,3,3-trifluoropropyl and 3,3,4,4,5,5,6,6,6-nonafluorohexyl radicals with poly(oxyethylene) hydrophiles. Their performance as aqueous surfactants was evaluated and compared to conventional methylsiloxane surfactants

Nonionic surfactants from fluoroalkenes
Journal of Fluorine Chemistry, 1985Abstract Perfluorinated alkenes obtained by degradation of PTFE [1] are easily attacked by nucleophiles. The reaction with poly(oxyethylenes) yields nonionic fluorosurfactants [2]: The F-nonionics I (RH) were transformed into the corresponding sulfates by sulfatation with chlorosulfonic acid.

Nonionic Surfactants: An Overview
Tenside Surfactants Detergents, 2010Abstract Nonionic surfactants do not produce ions in aqueous solution. As a consequence, they are compatible with other types of surfactants and are excellent candidates to enter complex mixtures, as found in many commercial products. Nonionic surfactants are found today in a large variety of domestic and industrial products, such as ...

Journal of the American Oil Chemists' Society, 1978
AbstractOver one billion pounds of nonionic surface‐active agents are produced per year in the U.S. alone. The oxyethylene derivatives of alcohols and alkylphenols account for 71% of this production. Methods of making these surfactants, along with descriptions of their properties and main uses in various detergents, are described.
