Palladium/iron bimetallic nanoparticles were synthesized using microemulsion method in the water-in-oil (W/O) microemulsion system, which was made up of iso-octane, cetyltrimethyl-ammonium bromide (CTAB), butanol and water and characterized by measuring the conductivity of the solution. Transmission electron microscope (TEM) and energy dispersive X-ray microanalysis (EDX) analysis showed that t...

Non-aqueous system are well known as solvent or drug suspension vehicles and oleogels micro emulsion with no aqueous phase (anhydrous, non-aqueous oil-in-oil emulsion) have had relatively scant attention yet may have uses as drug reservoir as well as template for the preparation of microemulsion combination with a cosurfactant. Microemulsions have emerged as novel vehicles for drug delivery whi...

An unusual phenomenon is observed for gelatin solutions (1.7-6.8%) in the microemulsion system of 0.3 M bis(2-ethylhexyl)sulfosuccinate sodium salt in isooctane and 14.5% distilled water. Highly viscous gels obtained at temperatures above 30 degreesC become free-flowing liquids at low temperatures (5-10 degreesC). This reversible temperature-dependent sol-gel transition phenomenon is used to im...

The main objective of this work was to prepare nanosized titania (TiO2) particles by mixed reverse microemulsion route. In this work titania was prepared by quaternary microemulsion system (water/surfactant/co-surfactant/ oil-phase). Span-80, Aerosol-OT, n-Propanol, Isooctane, and Titanium tetra isopropoxide (TTIP) were used as surfactant, co-surfactant, oil-phase and titania precursor respecti...

The novel carriers have been exploited through almost all the routes of administration. Association of drugs with carriers is normally noncovalent, based on collective strength of weak binding forces. Many newer carriers are evolving with the advent of technology and the demand of targeted delivery like microemulsions. Microemulsions are clear, stable, isotropic mixtures of oil, water and surfa...

This work presents the investigation of various capillary electrophoretic techniques for the Separation of low-molecular-weight phenolic and neutral lignin degradation products. A successful CE mode was micellar electrlokinetic chromatography (MEKC) with carrier electrolytes containing micelleformi:ng reagents, such as sodium dodecylsulfate. Important phenolic and neutr;al lignin degradation co...

The use of an inorganic phase in water-in-oil microemulsions has received considerable attention for preparing metal particles. This is a new technique, which allows preparation of ultrafine metal particles within the size range 5 nm<particle diameter<50 nm. This article presents a review of the current literature in the field of particle preparation of several metals such as silver, copper, ca...

BACKGROUND Similar to lipid emulsion propofol, microemulsion propofol also causes a high incidence of pain during intravenous injection. Various methods have been used to minimize the incidence and severity of pain on injection of lipid emulsion propofol. In this study, we investigated the effect of a lidocaine mixture on pain induced by microemulsion propofol injection, and sought to determine...

Covalent amphiphilic polyoxometalates generated from alkylphosphonic acids have been synthesized, characterized and monitored by multinuclear NMR spectroscopy. Among them, K3H[γ-SiW10O36(C12H25PO)2] has been successfully used as a surfactant for the stabilization of a Winsor I type microemulsion system.

In vitro compartmentalization of biochemical reaction networks is a crucial step towards engineering artificial cell-scale devices and systems. At this scale the dynamics of molecular systems becomes stochastic, which introduces several engineering challenges and opportunities. Here we study a programmable transcriptional oscillator system that is compartmentalized into microemulsion droplets w...
