Abstract

Hierarchically structured membranes composed of mesoporous silica embedded inside the channels of anodic alumina (MS-AAM) were synthesized using the aspiration method. Ethanol is shown to have a significant effect on the type and organization of the mesoporous silica phase. Detailed textural analysis revealed that the pore size distribution of the mesoporous silica narrows and the degree of ordering increases with decreasing ethanol concentration used in the synthesis mixture. The silica mesopores were synthesized with pores as small as 6 nm in diameter, with the channel direction oriented in lamellar, circular, and columnar directions depending on the ethanol content. This study reveals ethanol concentration as a key factor behind the synthesis of an ordered mesoporous silica–anodic alumina membrane that can increase its functionality for membrane-based applications.

 


She will use ARCHER supercomputer for 6 months to study behavior of biomolecules confined in ordered amorphous silica through all-atom molecular dynamic simulations with explicit water and counter-ions.The simulations will provide a better understanding of the interplay between the adsorbed proteins and mesoporous materials which is necessary to improve drug delivery systems by improving stability and controlled release of the active drug at the site of interest.
