Counter Diffusion in Aqueous Solution

Xiii. Counter Diffusion in Aqueous Solution

Sucrose diffusion in aqueous solution

The diffusion of sugar in aqueous solution is important both in nature and in technological applications, yet measurements of diffusion coefficients at low water content are scarce. We report directly measured sucrose diffusion coefficients in aqueous solution. Our technique utilises a Raman isotope tracer method to monitor the diffusion of non-deuterated and deuterated sucrose across a boundar...

Diffusion in the aqueous compartment

Measurements of diffusion of molecules in cells can provide information about cytoplasmic viscosity and structure. In a series of studies electron-spin resonance was used to measure the diffusion of a small spin label in the aqueous cytoplasm of mammalian cells. Translational and rotational motion were determined from the same spectra. Based on measurements made in model systems, it was hypothe...

Sonochemical degradation of azithromycin in aqueous solution

Background: The presence of pharmaceutical substances and their residual in water resources is an important environmental concern. Azithromycin, an antibiotic that is used for the treatment of infectious diseases, is a pollutant agent in the wastewater. The aim of this study was to investigate azithromycin degradation in aqueous solution through ultrasonic process in the presence of zinc oxide ...

Amino Acids in Aqueous Solution

In the previous chapter, the focus was mainly on the behavior of ions in solution. The effect of concentration, solvent, as well as pH have been investigated; furthermore, alkali metal ions as well as transition metal ions have been studied. In this chapter, the investigation will be extended from ions to molecules, more specifically toward the behavior of amino acids in solution. Amino acids a...
