Summary on Grant Application Form |

We propose a new approach to quantifying densification processes with the goal of predicting effects of composition geometry, atmosphere and temperature on densification by combining: 1) Quantum mechanical-based molecular orbital (MO) modelling of reaction pathways and molecular structure-property relationships of amorphous porous silica. 2) A topological (-D) description of elimination of porosity during three stages of densification. 3) Use of sol-gel processing to make porous silica monoliths with control over texture. The MO pathways that first shrink the diameter and then eliminate pores will be tested by measuring changes in matric and topological properties of gel-silica monoliths in controlled atmospheres and temperatures. MO predicted changes in IR and UV-Vis spectra of the partially densified samples will be compared with experimental spectra. Results will be used to improve performance of biological substrates for cell, organ cultures and environmental sensors with impregnation of optically active phases. The biological substrate technology is being developed at IC. The sensor matrices developed in this project will improve mechanical properties and environmental stability necessary for commercial product.
