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...

We present a droplet-based microfluidic platform for carrying out sequential and multiple reactions. Flexible droplet formation, multiple injections of additional droplets into pregenerated droplets, addressing of droplets into incubation chambers, and dosing of additional droplets to incubated droplets were achieved by the forward/reverse flow direction control and flow path control with pneum...

The addition of sterically stabilized colloidal particles to a phase-separating microemulsion leads to dramatic changes in its demixing behavior, especially during the later stages. Our microemulsion is composed of reverse micelles of sodium dodecyl sulfate, pentanol, and water in a dodecane continuous phase which separates into micelle-rich and micelle-poor phases above a lower critical soluti...

We discuss the design of reaction-diffusion systems that display a variety of spatiotemporal patterns. We also consider how these patterns may be controlled by external perturbation, typically using photochemistry or temperature. Systems treated include the Belousov-Zhabotinsky (BZ) reaction, the chlorite-iodide-malonic acid and chlorine dioxide-malonic acid-iodine reactions, and the BZ-AOT sys...

The betel plant (Piper betle L) is a that has the ability as an antifungal, antimicrobial and antioxidant. In order to make essential oil more efficient use, made into microemulsion. purpose of this study was determine effect stirring time temperature on characteristics microemulsions best produce microemulsion characteristics. This experiment used randomized block design (RBD) using two factor...

A comprehensive workflow approach is necessary to link multiple experimental tasks and identify microemulsion (ME) formulations with ‘optimal’ stability, displacement behavior technical feasibility in the petroleum industry. In this paper, a systematic described aid of case study which involves formulation an anionic sodium dodecyl sulfate-based microemulsion. The design such ME systems require...

We simulate the dynamics of phase assembly in binary immiscible fluids and ternary microemulsions using a three-dimensional hydrodynamic lattice-gas approach. For critical spinodal decomposition we perform the scaling analysis in reduced variables introduced by Jury et al. [Phys. Rev. E 59, R2535 (1999)] and by Bladon et al. [Phys. Rev. Lett. 83, 579 (1999)]. We find a late-stage scaling expone...
