Microwaves have been for their ability to heat water and food rapidly. And thanks to scientific technology and global marketing, the microwave oven was invented and got widely used in 1970's and 1980's. . Microwave radiation has specific...
There has been a considerable interest in the fabrication and characterization of molecular magnets. A complex that has garnered a great deal of attention is Prussian blue, Fe(III)4[Fe(II)(CN)6]3, and its transition metal cyanide...
We have found that dipolar molecules in non-polar solvents are selectively heated by microwave radiation that leads to the observation of enhanced chemical reactivity under microwave irradiation, often referred to as the "specific...
The sol-gel process is a synthetic approach that can yield silicon dioxide-based inorganic polymer materials of varying densities, pore volumes, and crystallinity. Depending on the initial conditions of the reaction, materials such as...
This dissertation is comprised with two main research projects: fabrication of thin films through an epoxide-catalyzed sol-gel process, and the dynamics of the photothermal initiation of Al/Fe2O3 metastable interstitial composite (MIC)...
Zeolite materials, in which transition metal ions have been substituted into the silicate or aluminosilicate framework, have been of considerable recent interest due to their potential as selective heterogeneous oxidative catalysts....
This research discussed in this dissertation is comprised of three distinct projects. The first is the fabrication of carbon-silica nanocomposites from the pyrolysis of acrylonitrile in a porous Vycor® glass to form dispersed carbon...
The use of binary inorganic solid-state fuel/oxidant redox processes typified by the classic aluminum/iron(III) oxide thermite reaction in combination with traditional energetic materials such as 2, 4, 6-trinitrotoluene (TNT), hexahydro-1...
ABSTRACT In the present work, Raman, resonance Raman and IR spectroscopy were used to investigate isolated vanadium and chromium sites homogeneously dispersed in a transparent silica xerogel matrix. The use of optical monolithic glasses...
Mn-silicalite-2 was synthesized at high pH using the molecular cluster, Mn12O12(O2CCH3)16 as a Mn Source. No precipitation of manganese hydroxide was observed with this cluster even with the use of tetrabutylammonium hydroxide as a...
Many industrially important heterogeneous catalytic reactions are not well understood. This lack is mainly due to the high reactivity and transient nature of the reactive sites and chemical intermediates involved. Monolithic, sol-gel...
The systematic incorporation of Cr ions in a phase-pure silicalite-2 lattice was accomplished through a hydrothermal synthesis using 3, 5-dimethylpiperidinium as a templating agent. The chromium ions, after calcination to remove the...
