Signatures of Overaging in an Aqueous Dispersion of Carbopol

Langmuir, 2020
In this work, we study the effect of the deformation field on the physical aging behavior of an aqueous Carbopol dispersion. It is composed of soft swollen particles of gel that get deformed and acquire a polygonal shape, with flat interfaces rendering the dispersion a soft solid-like consistency as filled volume fraction approaches unity.

Mixtures of gangliosides and phosphatidylcholine in aqueous dispersions

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1972
The interaction of ox brain gangliosides and pure egg phosphatidylcholine has been studied by taking aqueous dispersions of the two lipids in all proportions and centrifugating the dispersion at 100 000 × g for half an hour and measuring the amount and composition of the pellet and supernatant.

Aqueous Nanosilica Dispersants for Carbon Nanotube

Langmuir, 2015
Nanosilicas can disperse single-wall carbon nanotube (SWCNT) in aqueous solution efficiently; SWCNTs are stably dispersed in aqueous media for more than 6 months. The SWCNT dispersing solution with nanosilica can produce highly conductive transparent films which satisfy the requirements for application to touch panels.

Radiation response of vitamin A in aqueous dispersions

Journal of Agricultural and Food Chemistry, 1977
The radiation destruction of vitamin A acetate was monitored in isooctane, coconut oil, and aqueous dispersions. The G(-vit. A), i.e., the number of vitamin A molecules destroyed per 100 eV of energy absorbed in lipid solvents and aqueous preparations, increased with the concentrations of vitamin A used.

Thermotropic behavior of glycosphingolipids in aqueous dispersions

Biochemistry, 1985
The thermotropic behavior of 20 chemically related glycosphingolipids (GSLs) of high purity, containing neutral and anionic carbohydrate residues in their oligosaccharide chains, was studied by high-sensitivity differential scanning calorimetry. In general, the polar head group of GSLs appears to be one of the major determinants of their phase behavior.

Kinetics of growth on aqueous — oil and aqueous — solid dispersed systems

Journal of Applied Chemistry and Biotechnology, 1972
AbstractDispersed phase continuous culture systems are very complicated. Indeed, they can differ considerably in their behaviour from the usual homogeneous continuous culture systems. Experimental studies on cell adsorption—desorption rates under various conditions of surfactant concentrations and droplet coalescence and break‐up is needed in order to ...

Partitioning and stability of aqueous dispersions. Effect of electrolytes on the stability of aqueous dye dispersions

Langmuir, 1990
The effect of electrolytes on the stability of an aqueous dye dispersion has been studied by extracting the dispersion with a solvent in which the dye but not the dispersant is soluble. The amount of dye extracted from its dilute aqueous dispersion stabilized with a polymeric dispersant (sodium lignosulfonate) was found to increase with the 2/3 power ...

Colorimetric estimation of phospholipids in aqueous dispersions

Journal of Biochemical and Biophysical Methods, 1980
A method for the estimation of phospholipids in aqueous dispersions is described. The method is based on the formation of a lipid-molybdenum blue complex, which is extracted into chloroform from the aqueous phase. Phosphate ions, detergents, proteins, neutral lipids and various other ions do not interfere in the lipid estimation.

Stable aqueous dispersions of polyaniline

Journal of the Chemical Society, Chemical Communications, 1992
Relatively concentrated stable aqueous dispersions of polyaniline containing uniform spherical particles have been prepared for the first time using a underivatised poly(vinyl alcohol coacetate) as a steric stabilizer.
