Synthesis and Characterization of SiO2 Nanoparticles and

 · Chemical mechanical polishing (CMP) technology is extensively used in the global planarization of highly value-added and large components in the aerospace industry. A nanopowder of SiO 2 was prepared by the sol-gel method and was compounded into polishing slurry for the CMP of steel substrate. The size of the SiO 2 abrasives was controlled by varying the sol-gel reaction conditions.

Experimental study on using SiO2 nanoparticles along with

 · 1. Introduction. After secondary flooding more than half of the original oil in place (OOIP) remains in the reservoir due to trapping of oil in the reservoir rock pore spaces (Skauge and Palmgren 1989).One of the promising EOR methods is surfactant flooding where considerable reduction in interfacial tension between oil and water could effectively displace oil from the reservoir.

Fe3O4-TiO2 and Fe3O4-SiO2 Core-shell Powders

ABSTRACT. The interest for core-shells has been increased in the recent years due to their improved and modifiable properties. In this work Fe 3 O 4-TiO 2 and Fe 3 O 4-SiO 2 core-shells were successfully synthesized from an industrially produced magnetite-rich powder with micro- and nanometric particle sizes superparamagnetic behavior and saturation magnetization of 49 emu/g.
