Sum-frequency spectroscopy analysis of two-component langmuir monolayers and the associated interfacial water structure
Article Abstract:
Sum-frequency spectroscopy (SFS) in the CH and OH stretching regions is employed to obtain structural information about Langmuir monolayers on the H2O subphase of the model lipid dioctadecyldimethylammonium bromide and about the interfacial water structure underneath the films. The results correlates very well with surface pressure-area and surface-potential-area measurements and help obtain a good understanding of the interaction between the molecules of the mixed lipid.

Separating octadecyltrimethoxysilane hydrolysis and condensation at the air/water interface through addition of methyl stearate
Article Abstract:
A number of experiments have been conducted to investigate hydrolysis and condensation of chloro- and organo-silanes at the air/water interface. A study was therefore performed to induce octadecyltrimethoxysilane to follow a (3,0,0) to (0,3,0) to (0,0,3) sol-gel path through the addition of an inert filler molecule, methyl stearate. One object of the experiment was to distinguish between octadecyltrimethoxysilane hydrolysis and condensation.

Structural and dynamic properties of concentrated alkali halide solutions: A molecular dynamics simulation study
Article Abstract:
A systematic view of water structure in concentrated alkali halide solutions is presented using molecular dynamics simulations. The results show that the size of univalent ions in the solution has a significant effect on the dynamics of ions and other transport properties such as the viscosity that are correlated with the structural properties of water in aqueous ionic solution.
