PhD Thesis: “Nanometallurgy studies of transformations in the silica-silicon system ”
Supervisor: Professor Alexander Korsunsky
Patrick graduated from the Kwame Nkrumah University of Science and Technology with a major in Materials Engineering. He later received his Masters degree in Advanced Materials Science from the National University of Science and Technology, NUST MISiS. In 2018, Patrick was admitted to the Skoltech PhD in Materials Science and Engineering. Patrick’s research work aims at understanding the effects of transformations within the silicon oxygen system on the structure and properties of nanostructured silicon and silica based energy materials and designing cost effective and environmentally friendly synthesis routes to produce them. Some of his results have been published recently. At present his main focus of research is centered on silica and silicon based anode materials obtained from naturally occurring diatomaceous earth for improved performance in batteries.
