Contrasting melting behavior of zinc stearate and zinc oleate
Article Abstract:
The influence of a double bond in the middle of an otherwise flexible hydrocarbon chain on the melting of such assemblies is investigated by comparing the melting behavior of zinc stearate and zinc oleate. It is shown that the double bond effectively decouples the thermal evolution of conformational disorder in the chain segments on either side of the double bond and the melting of each of these segments in the assembly occurs as independent events.

Molecular dynamics study of the properties of capsaicin in a 1-octanol/water system
Article Abstract:
The all-atom and united-atom models of the Optimized Potential for Liquid Simulations (OPLS) force field were investigated to find out the most appropriate representation of capsaicin. Simulations revealed that capsaicin preferentially partitions to the octanol phase with its hydrocarbon segment oriented with that in octanol and the polar part remains exposed to the aqueous phase.

Effect of degassing on the formation and stability of surfactant-free emulsions and fine Teflon dispersion
Article Abstract:
The study demonstrates that the formation of surfactant-free, oil-in-water emulsions is significantly enhanced by the almost complete removal of dissolved gases. The removal of dissolved gases enables the formation of much more turbid and stable hydrocarbon oil in water emulsions and degassing was also found to enhance the dispersion of fine Teflon particles in water.
