New paper in Microporous and Mesoporous Materials

SiloGraphicalAbstract2017We are pleased to announce a new research article, "Effect of stirring rate on the morphology of FDU-12 mesoporous silica particles" published by NICE group members  Silo Meoto, Niall Kent, Michael Nigra, and Marc-Olivier Coppens in Microporous and Mesoporous Materials.

 

Abstract

Ordered mesoporous FDU-12 silica particles with different morphologies were synthesized by varying the stirring rate. The mesoporous structure and textural properties of the FDU-12 samples were characterized by N2 adsorption and desorption, scanning electron microscopy, transmission electron microscopy and small angle X-ray scattering. The influence of the stirring conditions on the morphology was demonstrated, as the FDU-12 particle morphology changes from a regular, hexagonal platelet to a poorly defined shape when the stirring rate is changed from slow to fast. At very fast stirring rate, shear influences the mesophase structure, although the pore diameter and wall thickness remain unchanged.

 


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.
