3Quartz is the name that geologists have ascribed to the crystalline form of silicon dioxide.
4In 2007 silicon dioxide was replaced with a metal oxide, again resulting in performance improvements.
5It was nebulized in a spray dryer using colloidal silicon dioxide as a drying adjuvant.
1The purification procedure entailed ethyl acetate extract, silica gel column, and thin layer chromatography.
2The extracts were then further purified with SPE silica gel tubes deactivated with trimethylamine.
3The dimer fraction was separated by size-exclusion chromatography (SEC) after pre-fractionation on silica gel.
4After removing the template by calcination, porous dehydrated silica gel nanoshells of uniform size were obtained.
5Both extracts were subjected to silica gel column chromatography for isolation of main constituents, followed by purification in sephadex.
