Preparation of Amorphous Aluminum Oxide-Hydroxide Nanoparticles in Amphiphilic Silicone-Based Copolymer Microemulsions

Polymerization of w/o Microemulsions for the Preparation of Transparent SiO2/PMMA Nanocomposites

“…Microemulsions have received considerable interest because of their small droplet size and complex structural behavior. The structural features depending on the microemulsion composition can be used to prepare particles a few nanometers in diameter by hydrolytic decomposition of molecular precursors or precipitation of ionic salts. − Some of the more recent examples are the preparation of complex oxides such as BaAl 12 O 19 , aluminum oxide-hydroxide, Ba(Mg 1/3 Ta 2/3 )O 3 , iron oxide, , BaTiO 3 , , ZnO, and sulfated zirconia for catalytic applications …”

Sulfated Zirconia Nanoparticles Synthesized in Reverse Microemulsions: Preparation and Catalytic Properties

“…The fundamentals of nanoparticle syntheses in microemulsions have been described by Lade et al and in several monographs. , The microemulsion technique has been used to a wide extent for the preparation of metal catalysts. − Only recently, more and more oxides are reported. Ying has reported the microemulsion-mediated preparation of BHA catalysts for high-temperature applications with surface areas in excess of 100 m 2 g -1 even after calcination at 1573 K. − Recent studies have focused on ultrafine particles of aluminum oxide−hydroxide, Ba(Mg 1/3 Ta 2/3 )O 3 , cerium oxide, − TiO 2 , − erbium oxide, iron oxide, − BaTiO 3 , − ZnO, , and manganese oxide …”

Syntheses and properties of ethoxylated double-tail trisiloxane surfactants containing a propanetrioxy spacer

“…This limits their application scope. However, in recent years research on trisiloxane surfactants had focused on the relationship between structure and spreading properties,5–7 spreading mechanism8–10 and other application performances 11, 12. There are few studies on their hydrolysis resistance.…”
