Synthesis of Nanometer-sized Yttrium Oxide Particles in Diisooctyl Sodium Sulphosuccinate (AOT)/Isooctane Reverse Micelle Solution
This thesis describes the synthesis of yttrium oxide nanoparticles in an AOT/isooctane reverse micelle solution. Two synthetic methods are compared. First is the precipitation reaction between yttrium nitrate and ammonia, second is the hydrolysis of yttrium isopropoxide. The effects of annealing of the resulting the yttrium oxide nanoparticles are also described. The nitrate method produced net...

Hydrogen evolution and consumption in AOT–isooctane reverse micelles by Desulfovibrio gigas hydrogenase
The enzyme hydrogenase isolated from the sulphate reducing anaerobic bacterium Desulfovibrio gigas was encapsulated in reverse micelles of AOT–water–isooctane. The enzyme ability to consume molecular hydrogen was studied as a function of the micelle size (given by Wo = [H2O]/[organic solvent]). A peak of catalytic activity was obtained for Wo = 18, a micelle size theoretically fitting the heter...
متن کاملEffect of Compressed Co2 on the Properties of Aot in Isooctane Reverse Micellar Solution and Its Application to Recover Nanoparticles
Effect of compressed CO2 on properties of the sodium bis(2-ethylhexyl) sulfosuccinate (AOT)/isooctane/water reverse micellar solution has been studied by phase behavior measurement. UV-vis study indicates that TiO2 in the reverse micelles can be precipitated by compressed CO2 at suitable pressures, while the surfactant AOT remains in the solution. Using this concept, TiO2 nanoparticles synthesi...
متن کاملThe experimental study of reverse micellar phase in AOT/ Heptane/ (Water or aqueous) as nano template
In this paper electrical conductivity measurements and optical investigations takes place in AOT/ heptane/ (water or aqueous) systems. The water in oil system prepared with adding water in 50% by weight of AOT/ heptane solution. In other systems instead of water, aqueous solutions of 1) zinc acetate and water 2) Potassium Hydroxide and water were used. In each phase, the trend of the electrica...
