Mechanism of Formation and Structure of Micro Emulsions by Electron Microscopy

Surfactant effects on the microstructures of Fe3O4 nanoparticles synthesized by microemulsion method

“…Among these synthesis methods, microemulsion method is a novel method for nanoparticles preparation and has been widely used to synthesize various kinds of nanomaterials in recent years, such as catalytic and magnetic materials [16,[19][20][21][22]. Microemulsions are thermodynamically stable dispersions of immiscible water phase and oil phase stabilized by the arrangement of surfactant and co-surfactant molecules at the interface [23]. The microemulsion, especially water-in-oil (W/O), which consists of water nanodroplets dispersed in the bulk oil phase and is stabilized in spherical reverse micelles, can be considered as "nanoreactor" for the synthesis of nanoparticles.…”

Preparation of nanoparticles of silver halides, superconductors and magnetic materials using water-in-oil microemulsions as nano-reactors

“…They explained that microemulsions were spontaneously formed with the uptake of water or oil due to the negative transient interfacial tension which allows the free energy to decrease as the total oil-water interfacial area increases [5,6]. At equilibrium, the oil/water interfacial tensions become zero or a very small positive number of the order of 10-2-10 .3 mN/m.…”

Study of Microemulsion Composition Effect over Phosphorescence Emission of a Polycyclic Aromatic Compound

“…The influence of thallium nitrate is shown in Figure 4a; the phosphorescent intensity increases until a plateau is reached above 0.031 M of TlNO 3 . This behavior is due to the increase in the intercrossing systems with the increase in thallium nitrate concentration, causing the growth in the population of molecules in the triplet state, until no intercrossing can be produced.…”
