Journal ArticleDOI
Synthesis of nanosize silica in a nonionic water-in-oil microemulsion: Effects of the water/surfactant molar ratio and ammonia concentration
TL;DR: The effect of ammonia concentration on the region of existence of single-phase water-in-oil microemulsions has been investigated for the system polyoxyethylene (5) nonylphenyl ether (NP-5)/cyclohexane/ammonium hydroxide and shows a complex dependence of the particle size on the water-to-surfactant molar ratio (R) and on the concentration of ammonium Hydroxide.
Journal ArticleDOI
Preparation of SiO2 nanoparticles in a non-ionic reverse micellar system
TL;DR: In this paper, the preparation of nanosize, monodisperse silica particles by controlled hydrolysis of tetraethoxysilane (TEOS) in a non-ionic surfactant/ammonium hydroxide/cyclohexane reverse micellar system is described.
Journal ArticleDOI
Aggregation, reversed micelles, and microemulsions in liquid-liquid extraction: the tri-n-butyl phosphatediluent-water-electrolyte system
TL;DR: In this article, the experimental evidence (e.g., distribution, viscosity, conductivity, and molecular weight measurements) suggesting the presence of aggregates in TBP extracts is assembled and critically reviewed.
Journal ArticleDOI
Aqueous stability of thorium and rare earth metals in monazite hydrometallurgy: Eh–pH diagrams for the systems Th–, Ce–, La–, Nd– (PO4)–(SO4)–H2O at 25 °C
TL;DR: In this paper, the potential vs. pH or Eh-pH diagrams for the systems Th, La, Nd, Ce, and La-PO 4 -H 2 O at 25°C were generated using the HSC5.0 software.
Journal ArticleDOI
Synthesis of Nanosize Silica in Aerosol OT Reverse Microemulsions
TL;DR: In this article, the authors used the fluorescence spectra of 1,3,6,8-pyrenetetrasulfonic acid (PTS) trapped in the water pools to demonstrate that free water molecules do not become available until the waterto-surfactant molar ratio (R) exceeds about 10.
