“…The variation with temperature of the disjoining pressure of a 100Å layer of water between two quartz plates has been measured and inflections at about the same temperatures have been observed [6,7]. The temperature dependence of the diffusion coefficient of thiourea in water has kinks at approximately, 15, 30, 45, 60ºC [9].

The anomalies that appear at every multiple of 15 o C in the viscosity of a thin liquid film of water and of water near solid interfaces are explained in this paper by comparing the thermal wavelength and molecular free volume of water, and quantum numbers are found. The possibility that these anomalies are related to the preferred and/or lethal temperatures of organisms is considered. The toxicity of heavy water (D2O) can also be explained with this approach.

The pulsation diffusion method is used successfully for the determination of diffusion coefficients in different systems (selfdiffusion, binary and ternary mixtures) and in connection with diffusion separation in liquids. The main advantage is the enhancement of matter transport by periodic flow e. g. in a capillary. Adapting a computation by P. L. Kapiza it is reported on a general treatment for the special conditions in a pulsation diffusion apparatus. Transport behavior depends strongly on hydrodynamic and mass transfer parameters. The results are important for the application of the pulsation method for measuring diffusion coefficients and for separation problems.

“…This arrangement leads to a considerable increase in the diffusion transfer. Therefore the method of pulsation diffusion has found several methodical and other applications [5][6][7][8][9][10][11]. Especially the standard pulsation diffusion arrangement with a capillary has proved to be appropriate and worthwhile for fast and precise determination of diffusion coefficients.…”

A new method to measure diffusion coefficients is described. It uses a pulsationdiffusion cell combined with a spectrophotometer which provides extinction-time curves. From these the diffusion coefficients can be determined. Nonlinearities between the diffusion current and the diffusion coefficient are taken into account, using a graphic method. It is based on the computation of the enhanced diffusion transfer during pulsation. The results are discussed and compared with data from the literature.
