Polyelectrolytes in multivalent salt solutions
ELECTROPHORESIS, 2011AbstractWe study conformational and electrophoretic properties of polyelectrolytes (PEs) in tetravalent salt solutions under the action of electric fields by means of molecular dynamics simulations. Chain conformations are found to have a sensitive dependence on the salt concentration Cs.

Charging of glycogen in salt solutions
Biochimica et Biophysica Acta (BBA) - General Subjects, 1969Abstract The disc-electrophoretic method with polyacrylamide gel was successfully adapted to demonstrate the differential charging of glycogen in solutions of more or less neutral sodium salts (halides, sulfate, nitrate, thiocyanate, and organic acids) and in more alkaline solutions (NaOH, Na3PO4, Na2CO3). The relative mobility followed the lyotropic

Preparation of sugar-salt solutions
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1984Correct measurement techniques are essential for the preparation of oral rehydration solutions but dangerous or ineffective solutions may also result from the inherent variability of the method and ingredients. This paper describes an experimental study conducted in Zimbabwe to compare the reliability of three methods for measuring sugar and salt in a ...

Salting-In and Salting-Out of Water-Soluble Polymers in Aqueous Salt Solutions
The Journal of Physical Chemistry B, 2012To obtain further experimental evidence for the mechanisms of the salting effect produced by the addition of salting-out or sating-in inducing electrolytes to aqueous solutions of water-soluble polymers, systematic studies on the vapor-liquid equilibria and liquid-liquid equilibria of aqueous solutions of several polymers are performed in the presence ...

The cooling of a salt solution
Journal of Engineering Physics, 1986Self-similar formulation is used to demonstrate the possibility of a regime involving formation of a zone with two-phase state. The boundary is found between crystallization regimes with abrupt phase transition front and with extended mixture zone.

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1973
The nucleation of a number of sparingly soluble electrolytes has been studied by a precipitation method and interfacial free energies have been estimated using vapour nucleation theory. The results have been correlated with those obtained by other workers for aqueous solutions by precipitation or by the super-cooling technique.

Polyelectrolytes in salt solutions
Journal of Polymer Science Part A: General Papers, 1964AbstractIt is shown that the exceptionally low expansion values expected by Kimball, Cutler, and Samuelson's theory result from their interpretation of the Gaussian distribution function for polymer chain segments rather than a statistical mechanical additivity problem.

JAMA: The Journal of the American Medical Association, 1898
Chicago, Aug. 17, 1898. To the Editor: —Have just been reading the really valuable article, "Saline Infusions" ( vide Journal, August 6, p. 306), and its suggestions will doubtless have great weight with many practitioners. In view of that fact, I thought it might be well to call attention to a typographic error in the fourth line from the top of ...
