A Geometallurgical Approach to Assessing Critical Metal Mobility and Recoverability from Ultramafic Mine Tailings
DownloadFall 2022
Critical metals (e.g., nickel and cobalt) are increasingly in demand for the production and storage of cleaner energy but their supplies are finite. Ultramafic mine tailings could be reprocessed as a source of critical metals. These waste materials host an array of critical transition metals and...

This dissertation describes the use of a novel Pt deposition to prepare nickel- and carbon-supported platinum catalysts. The deposition is referred to herein as the platinum counter electrode deposition. The source of platinum is the sacrificial dissolution of a blacked platinum counter electrode...

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)...

A calorimeter for the deposition of metal during free-flight GMAW was developed for the purpose of measuring droplet heat content in Ni/WC tubular wires. By approximating the thermal gradients within the calorimeter to be second order polynomials the energy transferred to the calorimeter by the...
