A New Approach to Molecular Hydrodesulfurization Catalysts: Allyl-capped Trialkylphosphoranimide-bridged Late First-row Transition Metal Clusters
DownloadFall 2017
A series of new trialkylphosphoranimide allyl-capped clusters [M(ƞ3-allyl)(NPR)3]2, (M = Fe, Co or Ni, R = Et, tBu or Ph) were synthesized. The nickel dimers [Ni(ƞ3-allyl)(NPR3)]2, R = Et, Ph are diamagnetic and have been fully characterized using NMR spectroscopy, X-ray crystallography,...

Confined Uniaxial Compaction Observing Triaxial Response of Granular Media under Quasi-static Loading Conditions
DownloadFall 2019
Experimental studies have been carried out in this thesis to enhance the understanding of granular material failure by observing the effects of particle size on material properties. Understanding the granular behaviour of materials is important in pharmaceutical research, product quality in the...

Nicewicz, Piotr, Peciar, Peter, Macho, Oliver, Sano, Tomoko, Hogan, James D.
The quasi-static confined uniaxial compaction of granular alumina and boron carbide was studied, and the effect of triaxial stress on the materials as a function of increasing particle size was observed. The average particle sizes studied for granular alumina were 170 ± 63, 230 ± 55, 330 ± 67,...
