According to an earlier hypothesis of one of us on the surface equation of state, extendedchain surfactants usually adsorb in (at least) two different surface configurations depending on the surface area available per adsorbate molecule. Evidence for the continuous transition between the different surface configurations in the equilibrium state is provided by thermodynamic (surface tension), rheological...
The structure and growth dynamics of two dimensional aggregation of 1 µm polystyrene latex particles trapped at the air-water interface have been observed. For some time after induction of growth rather compact clusters grew slowly; thereafter the clusters became much more mobile and rapidly aggregated into more ramified structures. The clusters were fractal, the Rg2-N plot plot...
Light scattering from thermally excited capillary waves has been used to study normal liquid alkanes (15 to 18 carbon atoms in length) as a function of temperature. In all cases the frequency and damping of the surface waves exhibit well-defined discontinuities at a temperature near, but distinct from the melting point. Above that temperature the dat behave as expected for a clean liquid surface;...
The high frequency (4×104<ω<4×105 s−1) surface viscoelasticity of aqueous solutions of some primary alcohols has been studied by light scattering from capillary waves. The principal conclusion is that the surface dilational viscosity appears to have negative values. From the effects of such negative surface viscosity it is shown that the experiments could reliably distinguish between positive...
