ABSORPTION OF ISOFLURANE BY SILICA GEL

open access: yesBritish Journal of Anaesthesia, 1991
We have studied the capacity of the drying agent silica gel (SG) to absorb isoflurane from gas samples. When dry, SG was able to absorb 31 times its own volume of isoflurane vapour, which could be recovered almost completely from the SG by displacement with water vapour. However, we were unable to demonstrate any significant absorption of isoflurane by

Hydrophobic adsorption and covalent immobilization of Candida antarctica lipase B on mixed-function-grafted silica gel supports for continuous-flow biotransformations [PDF]

open access: yes, 2013
Adsorption onto solid supports has proven to be an easy and effective way to improve the mechanical and catalytic properties of lipases. Covalent binding of lipases onto the support surface enhances the active lifetime of the immobilized biocatalysts ...

Synthesis and Characterization of Modified Silica Gel from Teff Straw Ash Using Sol-gel Method

open access: yesNext Materials
Teff straw ash was first converted into sodium silicate solution, then processed via sol-gel, producing low-density silica aerogel (modified silica gel). A one-step modification method was applied to produce modified silica gel from teff straw ash.
