Abstract

The rate of effusion of argon through a sol-gel scaffold will be measured to determine the size of the pores. The effusion rate will then be used to correlate initial pore size to any pore shrinkage that occurs. We will attempt to control the initial pore size by using various-sized paraffin beads as templates throughout the organically modified tetramethoxysilane (TMOS) gel scaffold. Polyethylene glycol (PEG) will also be used to prop open the pore openings and keep them from closing during the drying process.
