Synthesis of Nanometer-sized Yttrium Oxide Particles in Diisooctyl Sodium Sulphosuccinate/Isooctane Reverse Micelle Solution
… 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 …

Amyloid Fibril Nucleation In Reverse Micelles
… high interest. When Abeta is encapsulated in a reverse micelle, its infrared spectrum indicates that it spontaneously adopts a fibril-like structure, which is remarkable because only one Abeta strand is present in each reverse micelle. That observation suggests that some aspect of the reverse …

Quantitative Model for the Prediction of Hydrodynamic Size of Nonionic Reverse Micelles
The sizes of nonionic reverse micelles were investigated as a function of the molecular structure of the surfactant, the type of oil, the total concentration of surfactant [NP], the ratio of NP4 to total surfactant (r), the water to surfactant molar ratio (ω), temperature, salt concentration, and …

The effect of temperature and crystallite size on the growth and morphology of carbon nanotubes
… sizes supported on y-A120 3 using the reverse micelle technique. It was hypothesised that changing the crystallite size of the synthesised iron oxide crystallites could lead to the control of the external nanotube diameter. The effect of temperature on the external diameter and …

Strategies for targeting cancer: small molecules, epigenetics and drug design
… to be utilized in novel drug design. In my reverse micelle study, the hydrolysis of the Schiff-base compound was observed to be dependent on the size of reverse micelles; resulting in partial phase selectivity. The reverse micelle model provided ample support for engineering various types of …

Subcutaneous and oral delivery of insulin
… of chitosan. Solubilization of the PEC in a reverse micelle formulation (RMF) and administration to diabetic rats resulted in an oral delivery system for insulin with acceptable bioactivity. The effect of reduced (GSH) and oxidized (GSSG) glutathione on the bioactivity of insulin was studied. …

Selective extraction of colorful proteins using reverse micelles
… method of liquid-liquid extraction using reverse micelles is one such technique. While this technique has been researched in the past, previous studies lack information about realistic complex protein mixtures.</p> <p>Through this study optimum conditions were found for the individual …

Sintering of Co2MnO4 spinel for protective coatings in SOFC
… gel-combustion, co-precipitation and reverse micelle) and the obtained specific surface area, structure and particle size were correlated with thermal behaviour, sintering temperature and achieved density. It was found that regardless the synthesis process the only obtained phase is …

Preferential oxidation of carbon monoxide in hydrogen-rich gases over supported cobalt oxide catalysts
… interactions) were synthesised using the reverse micelle technique from which nanoparticles with a narrow size distribution were obtained. Certain properties of the microemulsions prepared were altered to obtain five catalysts with varying Co₃O₄ crystallite sizes averaging between 3.0 and …

Magnetic Nanoparticles Based on Iron: Synthesis, Characterization, Design, and Application
… and α-iron-iron oxide was accomplished through reverse micelle routes and high temperature decomposition of iron pentacarbonyl in various media. Structural analysis to confirm the structures was performed using extended x-ray absorption fine structure (EXAFS) techniques. A rapid characterization …

Structure, Function & Dynamics At The Membrane
… that the protein was correctly folded in the reverse micelle solution used as a membrane mimetic, cardiolipin was introduced to confirm two previously predicted sites of interaction as well as to identify and propose a novel third site. Next, NMR-derived methyl side chain order parameters have …

Effects of Crystallite size and water partial pressure on the activity and selectivity of low temperature iron-based fischer-tropsch catalysts
… achieved through the utilisation of the reverse micelle technique. Size control can be achieved through variation of the water to surfactant ratio, with a high ratio leading to larger crystallites being formed. An even distribution of metal crystallites onto the support material was …
