The observed trends of this quantity as a function of the surfactant concentration were rationalized using a mass-action model for the alcohol distribution between the aqueous and the micellar phase. At the same time, the model was revised to account for the alcohol effect on the surfactant ...

Gas chromatography-mass spectrometry was employed for the analysis of furfural impurities. A comprehensive consistency analysis was performed for the obtained data. The experimental data were correlated with the NRTL, UNIQUAC and Wilson activity coefficient models. The results were compared with the ...
“microdosing” studies to evaluate the pharmacokinetics of novel drug compounds22,23,24,25, extends the distance/time over which tracers can be transported to the imaging site26, and is critical in preclinical research, where much higher concentrations of the tracer per mass of the animal must...

Densities of the ternary system water-sodium dodecylsulfate (NaDS)-pentanol and of the binary systems butanol-octane and pentanol-octane were measured at 15, 25, and 35 掳C. The apparent molar volume of pentanol in the ternary system was analyzed using a mass-action model for the alcohol ...
Finally, 80-nm thick Au was thermally evaporated with a shadow mask under vacuum at 2 × 10−6 torr to act as the cathode. Measurements and characterization: Devices with an active area of 0.3 cm × 0.3 cm were characterized in air under an Air Mass 1.5 Global (AM 1.5 G) solar ...
