Planck tension

Here, N is the number of molecules (monomers) per mole, k is the Boltzman constant, T is absolute temperature, h is Planck s constant, AGj is a term denoting the mobility of the hpid molecules, j is interfacial tension, Tf is melting temperature, and Hf is latent heat of fusion. The first exponential term in Equation 1 has been related to the ability of a lipid molecule to attain the necessary conformation to become attached to the crystal lattice, and it is often given as (20)... 

Experiments with a maximum bubble pressure and a drop volume set-up were performed with aqueous solutions of an oxyethylated para-tertiary butyl phenol with 10 EO-groups, pt-BPh-EOIO (synthesised and purified by Dr. G. Czichocki, Max-Planck-Institut fur Kolloid- und Grenzflachenforschung Berlin). The dynamic surface tension of a 0.025 mol/1 solution of pt-BPh-EOlO is shown in Fig. 5.30.
