Mixed monomolecular films of chlorophyll and cytochromes.
Mixed monomolecular films of cytochrome (Cyt) and chlorophyll (Chl) were spread at a nitrogen-water interface. A large interaction is observed between reduced Cyt f and Chl a in a mixed film. Oxidized Cyt f and Chl a in a mixed film show little evidence for interaction. Mixed monomolecular films of Chl a with either reduced or oxidized Cyt c appears to result in denaturation of the protein at t...
متن کاملViscoelastic relaxation of insoluble monomolecular films
2014 Glycerol mono-oleate monolayers at the air-water interface have been investigated by quasielastic light scattering from thermally excited capillary waves over a wide range of wave numbers. Using a relatively novel data analysis procedure four surface viscoelastic properties were deduced ab initio from the light scattering data : surface elastic moduli and viscosities governing shear normal...
متن کاملNonlinear optical studies of monomolecular films under pressure.
Nonlinear optical techniques (second-harmonic and sum-frequency generation) have been used to study the structure of organic molecules that are confined and compressed between a lens and a flat surface. The molecules studied include self-assembled monolayers of n-octadecyltriethoxysilane and Langmuir-Blodgett films of stearic acid, octadecylalcohol, octadecylamine, and a liquid-crystal molecule...
متن کاملAutoxidation of cholesterol in aqueous dispersions and in monomolecular films.
The autoxidative formation of 7-ketocholesterol and diols from aqueous cholesterol dispersions and from cholesterol monomolecular films has been studied as a function of time. The rate of oxidation of cholesterol is much faster at the surface than in the bulk. Whereas more than one-half of the cholesterol is oxidized at the surface within 8 hr at room temperature, no noticeable reaction was obs...
متن کاملTribochemistry of monomolecular lubricant films of ethanolamine oligomers
The aim of present study was to find out the influence of oxygen and nitrogen containing ethanolamine oligomers on the tribological behavior. X-ray photoelectron spectroscopy (XPS) was used to obtain insight into the molecular mechanisms leading to the macroscopic lubricity. Monomolecular lubricant films were deposited onto ultra thin copper films sputtered onto silicon wafers. Surfaces covered...
