The inverse gas chromatography, (IGC), method has been used extensively to study the structure of polymers, the interactions of various liquids and gases with polymeric materials, and polymer-polymer miscibility. The method is simple, fast and economical and provides valuable thermodynamic information for characterization of polymeric materials1−6. In this study, we examined the interactions of...

In connection with the problem of the determination of the cardiac output by the use of ethylene (13), it seemed of interest to investigate further the nature of the forces which make the solubility of this gas 1% times as great in human blood as it is in water. The general problem of the nature of the factors which determine the solubility of gases in blood is of importance not only because of...

A simple and rapid in vitro chemical solubility test applicable to industrial uranium trioxide (UO3) was developed together with two in vitro cellular tests using rat alveolar macrophages maintained either in gas phase or in alginate beads at 37 degrees C. Industrial UO3 was characterized by particle size, X-ray, and IR spectra, and chemical transformation (e.g., aging and hydration of the dust...

The hygroscopic growth of aerosol particles present in a boreal forest was measured at a relative humidity of 88%. Simultaneously the gas phase concentration of sulfuric acid, a very hygroscopic compound, was monitored. The focus was mainly on days with new particle formation by nucleation. The measured hygroscopic growth factors (GF) correlated positively with the gaseous phase sulfuric acid c...

â  performance and capacity of sulfur recovery unit (sru) are greatly affected by the h2s:co2 ratio of the acid gas stream. the acid gases in iran contain around 35 mol% h2s and 60 mol% co2. this low concentration of h2s calls for more complex sulfur plant, larger equipments, and higher costs. acid gas enrichment processes (age) is run to upgrade low quality acid gas collected from gas treating...

The solubility of nitrous oxide in blood at body temperature was determined by Siebeck (1) with considerable accuracy as early as 1909. In his experiment, the blood was placed with a gas mixture in a tonometer of 3 liters capacity and equilibrated at 38” and atmospheric pressure. After an equilibrium had been attained, samples of both blood and gas were analyzed for nitrous oxide content. A blo...

1. The solubility of d-valine in water has been determined over a range of 0-60 degrees . 2. The solubility of this amino acid varies with the mode of crystallization, indicating a dependence of solubility on the crystal form.
