Alkoxy Chain Effect on the Viscosity of a Quaternary Ammonium Ionic Liquid: Molecular Dynamics Simulations
(AMER CHEMICAL SOC, 2009)
The viscosity of ionic liquids based on quaternary ammonium cations is reduced when one of the alkyl chains is replaced by an alkoxy chain (Zhou et al. Chem. Eur. J. 2005, 11, 752.). A microscopic picture of the role played ...
Equilibrium And Kinetic Study Of Chromium Sorption On Resins With Quaternary Ammonium And N-Methyl-D-Glucamine Groups
The equilibrium and kinetics of chromium (VI) adsorption on a new synthesized resin containing both N-methyl-D-glucamine and quaternary ammonium functional groups P(VbNMDG-co-ClVBTA) have been presented. The results obtained ...
Quaternary Ammonium “Tannate” for Antifouling Coatings
(American Chemical Society, 2012-12)
The undesirable accumulation of a wide variety of marine organisms (biofouling) on ship hulls can lead to significantly increased costs, principally by increased fuel consumption to maintain cruising speed. Generally, these ...
Potentiometric response of polymeric liquid membranes based on quaternary ammonium salts for nitrate ion determination
(SOCIEDAD CHILENA DE QUIMICA, 2004-09)
Polymeric liquid membranes are prepared using 3-nitro-o-xylene (NOX), tri-butylphosphate (TBP), bis-(2-ethylhexyl) sebacate (DOS), o-nitrophenyloctyl ether (o-NPOE), tris-2-ethylhexylphosphate (TEHP), dioctylphthalate (DOP) ...
Optimizing resin-dentin bond stability using a bioactive adhesive with concomitant antibacterial properties and anti-proteolytic activities
Secondary caries and hybrid layer degradation are two major challenges encountered in long-term resin-dentin bond stability. As a link between resin and dentin, adhesives that possess both antimicrobial and anti-proteolytic ...
