Synthesis of monodisperse superfine silica with acid-catalytic hydrolysis of TEOS in W/O microemulsion;

The results studied by dilution method showed that a part of n-hexanol in n-heptane together with surfactant constructed a mixed film,which improved the molecular geometry of the mixed components and resulted in the formation of W/O microemulsion.

The states of water in the W/O microemulsions formed in H2O/C12-EOx-C12·2Br/n-hexanol/ n-heptane systems have been investigated by Fourier transform infrared spectroscopy(FT-IR).

Effects of W/O microemulsions on pharmacokinetics after intraduodenal administration, membrane fluidity and membrane transport of Rb_1 were studied in rats, liposomes and parallel artificial membrane permeability assay (PAMPA), respectively.

At first, Pd(NO3)2 was recycled from the waste Pd-C catalyst, then, the palladium nanoparticles with size of 5 nm to 200 nm were generated in the O/W microemulsion of sodium dodecyl sulfate (SDS), Brij30 and H2O system by using nonionic surfactant Brij30 as the reducing agent.

Fine particles of polyaniline were prepared in (An+O/W microemulsion)two phase system in which the An phase was used as a monomer source and the O/W microemulsion phase for polymerization.

In this paper, a review is presented focusing on the application of reversed micelles or w/o microemulsions to synthesizing nano-sized ultrafine particles, including precip itation in reversed micelles, preparation of colloidal catalysts, preparation of semi-conductors, magnetic particles and ceramic powders, etc.

Mechanism of solutes extraction using reversed micelle or W/O microemulsion;

Preparation of ultrafine MgO particles in W/O microemulsions;

Palladium nano-particles were synthesized by W/O microemulsion composed of nonionic surfactant (alkylpolyglycol ethers) named Marlipal O13/50, water and cyclohexane.
