Stability of stearic acid monolayers on artificial sea water
We studied the formation and stability of Stearic Acid (SA) based films on aqueous sub-phases via Langmuir trough and imaging ellipsometry experiments. The aqueous phase was based on Artificial Sea Water (ASW), a multicomponent salt solution with a total molarity of 0.53. The composition of this 10 solution was varied via dilution (1, 10 and 100 times) and adjustment of the pH (3, 7, 10). Also ...
متن کاملGrowth and Dissolution of Calcite in the Presence of Adsorbed Stearic Acid.
The interaction of organic molecules with the surface of calcite plays a central role in many geochemical, petrochemical, and industrial processes and in biomineralization. Adsorbed organics, typically fatty acids, can interfere with the evolution of calcite when immersed in aqueous solutions. Here we use atomic force microscopy in liquid to explore in real-time the evolution of the (1014) surf...
متن کاملPhotodegradation of Stearic Acid Adsorbed on Superhydrophilic TiO2 Surface: In Situ FT-IR and LDI Study
TiO2 films prepared by template-assisted sol-gel method were characterized by X-ray diffraction spectroscopy, scanning and atomic force electron microscopy, and Fourier transform infrared (FT-IR) spectroscopy. Based on the hexane adsorption-desorption analysis, the films have a surface area of 390-540 m(2)/g with pore size distribution narrowly centered around 10 nm. Optimal component ratio and...
متن کاملMutations in SACPD-C Result in a Range of Elevated Stearic Acid Concentration in Soybean Seed
Soybean oil has a wide variety of uses, and stearic acid, which is a relatively minor component of soybean oil is increasingly desired for both industrial and food applications. New soybean mutants containing high levels of the saturated fatty acid stearate in seeds were recently identified from a chemically mutagenized population. Six mutants ranged in stearate content from 6-14% stearic acid,...
متن کاملLangmuir monolayers as disordered solids: Strain-state calculations applied to stearic acid
Langmuir monolayers as disordered solids: Strain-state calculations applied to stearic acid" (1997). This paper presents a calculational procedure to determine the equilibrium phase for a given surface pressure . The monolayer is treated as orientationally free tails grafted to a two-dimensional net formed by the head groups of the amphiphilic molecules. The head groups form a subsystem with t...
