“…With the analogue molecular structures of phospholipids, they are also frequently used to form vesicles to mimic the cell membrane (13). In addition, the vesicle formed by din-hexadecyl phosphoric acid (n-C 16 H 33 O) 2 PO(OH), DHP, was used to synthesize CdS nanoparticles (14,15). Though the DHPsupported [Ru(bpy) 3 ] 2+ crystallites obtained from the monolayer of DHP on aqueous subphases containing [Ru(bpy) 3 ] 2+ was studied (16), the monolayers and Langmuir-Blodgett (LB) films formed by long alkyl phosphoric acid amphiphiles are rarely studied.…”

“…The effect of size on the electronic and optical properties of these nanosize particles is an area of fundamental interest during the growth of the crystallite from the molecular level to the bulk material [1]. Many approaches have been explored for the preparation of spherical ultrafine particles, including the use of colloids, polymers, glasses, and micelles to successfully control aggregation [2][3][4]. Many new and unusual physical and chemical properties also arise as particles attain nanosize dimensions [5][6].…”

Synthesis of Ag/SiO2 nanosize particles by reverse micelle and sol-gel processing

Ag/SiO 2 composite particles have been synthesized within reverse micelle via metal alkoxide hydrolysis and condensation. The size of the particles and the thickness of the coating can be controlled by manipulating the relative rates of the hydrolysis and condensation reactions of tetraethoxysilane (TEOS) within the microemulsion. The average size of the synthesized particles was in the size range of 20-40 nm. The effects of synthesis parameters, such as the concentration of the Ag solution, the molar ratio of water to TEOS, and the molar ratio of water to surfactant, are discussed.

Fe/SiO 2 core-shell type composite nanoparticles have been synthesized using a reverse micelle process combined with metal alkoxide hydrolysis and condensation. Nano-sized SiO 2 composite particles with a core-shell structure were prepared by arrested precipitation of Fe clusters in reverse micelles, followed by hydrolysis and condensation of organometallic precursors in micro-emulsion matrices. Microstructural and chemical analyses of Fe/SiO 2 core-shell type composite nanoparticles were carried out by TEM and EDS. The size of the particles and the thickness of the coating could be controlled by manipulating the relative rates of the hydrolysis and condensation reaction of TEOS within the micro-emulsion. The water/surfactant molar ratio influenced the Fe particle distribution of the core-shell composite particles, and the distribution of Fe particles was broadened as R increased. The particle size of Fe increased linearly with increasing FeNO 3 solution concentration. The average size of the cluster was found to depend on the micelle size, the nature of the solvent, and the concentration of the reagent. The average size of synthesized Fe/SiO 2 core-shell type composite nanoparticles was in a range of 10-30 nm and Fe particles were 1.5-7 nm in size. The effects of synthesis parameters, such as the molar ratio of water to TEOS and the molar ratio of water to surfactant, are discussed.
