Amphiphilic single and double networks: a small-angle X-ray scattering investigation
(2016)We investigated the microphase-separated morphologies of water-swollen amphiphilic single and double polymer networks using small-angle X-ray scattering (SAXS). The networks consist of (i) a first conetwork containing ...

Analytical separations using molecular micelles in open-tubular capillary electrochromatography
(2002)Open-tubular capillary electrochromatography (OT-CEC) is an alternative approach to conventional CEC. The primary advantage of OT-CEC is the elimination of problems associated with frits and silica particles in conventional ...

Aqueous size exclusion chromatography of random, diblock, and ABC triblock methacrylic polyampholytes
(1996)Aqueous size exclusion chromatography (SEC) at 1 M KCl and pH 8.5 was employed to probe the aggregation behavior of methacrylic polyampholytes. In agreement with earlier results obtained by light scattering techniques, ...

Can we use area per surfactant as a quantitative test model of specific ion effects?
(2004)The three main currently proposed approaches for understanding specific ion effects are briefly described. In some experimentally well defined and simplified situations, one can decouple ion specificity effects from all ...

Chaotropic salts interacting with soft matter: Beyond the lyotropic series
(2016)The effects of the chaotropic ions of the Hofmeister series on many systems and phenomena are typically quite pronounced. What happens, however, when one uses chaotropic ions beyond SCN−, ClO4 −, or guanidinium, which are ...

Controlled production of ZnO nanoparticles from zinc glycerolate in a sol-gel silica matrix
(2006)The controlled production of ZnO nanoparticles within an amorphous silica matrix is achieved using a new methodology consisting of four stages. First, precursor zinc glycerolate nanoparticles are produced within reversed ...

Hofmeister anion effects on surfactant self-assembly and the formation of mesoporous solids
(2002)Recent work on mesoporous silica formation using cationic and non-ionic templates has unveiled a large number of anion effects. Anions are seen to change the hydrolysis rates of the silicate precursors, affecting the surface ...

In vivo imaging of quantum dots encapsulated in phospholipid micelles
(2002)Fluorescent semiconductor nanocrystals (quantum dots) have the potential to revolutionize biological imaging, but their use has been limited by difficulties in obtaining nanocrystals that are biocompatible. To address this ...

Monolayers, bilayers and micelles of zwitterionic lipids as model systems for the study of specific anion effects
(2007)This work is a review of the effect of different monovalent anions (belonging to the Hofmeister series) on a single model amphiphile, phosphatidylcholine molecules in contact with water, in three different geometries, ...

Novel mixed metal Ag(I)-Sb(III)-metallotherapeutics of the NSAIDs, aspirin and salicylic acid: Enhancement of their solubility and bioactivity by using the surfactant CTAB
(2015)The already known Ag(I)-Sb(III) compound of the formula {Ag(Ph3Sb)3(NO3)} (1) and two novel mixed metal Ag(I)-Sb(III) metallotherapeutics of the formulae {Ag(Ph3Sb)3(SalH)}(2) and {Ag(Ph3Sb)3(Asp)}(3) (SalH2 = salicylic ...

Open-tubular capillary electrochromatography/electrospray ionization-mass spectrometry using polymeric surfactant as a stationary phase coating
(2004)We describe the use of the polymeric surfactant poly(sodium undecylenic sulfate) (poly-SUS) as a stationary phase coating in open-tubular capillary electrochromatog raphy (OT-CEC) coupled with electrospray ionization-mass ...

Solubilization and stabilization of carotenoids using micelles: Delivery of lycopene to cells in culture
(1999)The use of the organic cosolvents tetrahydrofuran and dimethylsulfoxide was found to be unsuitable for prostate tumor cell cultures because of solvent cytotoxicity and the poor solubility and instability of lycopene. For ...
