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,...

Activity, selectivity and stability enhancements often observed in bimetallic catalysts make them an inseparable part of today’s chemical industry. However, it is usually problematic to understand the real interactions resulting in such improvements due to the lack of control over the bimetallic...

Empowering the Base Metals: Rational Design of Homogeneous Catalysts for Hydrotreatment, and Reduction of Organic Unsaturates
DownloadFall 2013
Hydrocarbon-soluble, low-coordinate, phosphoranimide-supported complexes of the base metals (iron, cobalt and nickel) were developed and evaluated for a range of stoichiometric and catalytic bond-forming and bond-breaking transformations. An unprecedented family of tetrametallic clusters of Co(I)...

Bimetallicity is known to provide synergistic effects and improve catalytic performance of monometallic counterparts in a variety of applications. Conventional impregnation methods for supported catalyst preparation do not allow for the control of bimetallic nanoparticle structure or size, which...

Inhalable nanoparticles in lung cancer treatment; efficacy, safety, distribution and nanoparticle-macrophage interactions
DownloadFall 2012
In 2002, lung cancer was responsible for 17.6% of the total worldwide deaths from cancer. Beyond the three traditional forms of cancer treatment, surgery, radiation therapy, and chemotherapy, targeted drug delivery therapy has shown to be a potential treatment option. The design of a successful...

Mixed-Valence First-Row Metal Clusters for Catalytic Hydrodesulfurization and Hydrodeoxygenation
DownloadFall 2013
Salt metathesis between CoCl2 and [KNPEt3]n provides a new route to the halide-substituted cobalt phosphoranimide cluster [CoCl(NPEt3)]4. This cluster is a useful precursor for the preparation of alkyl-capped cobalt phosphoranimide complexes. The methylated heterocubane [CoMe(NPEt3)]4 was...

Macrophages are the primary cells of innate immunity that provide the first line of defence against any external stimuli. Their phagocytic properties enable them to engulf invading microbes or foreign particles. The phagocytic capability of macrophages plays a major role in interfering with drug...
