Dr. Offeh Gyimah earned his bachelor’s degree in Materials Engineering (2008) from the Kwame Nkrumah University of Science and Technology (KNUST), Ghana. He pursued a master’s degree focusing on the Advanced Materials-Nanomaterials from Ulm University, Germany (2012). His research work at Ulm focused on CO oxidation catalysis where, two existing setups (Microflow tube rector and DRIFTS) were technically improved and qualitatively characterized to enable kinetic and in-situ IR spectroscopic measurements on thin film Au/TiO2 model catalysts.
In 2013, he joined the Department of Mechanical and Automotive Technology Education of COLTEK-UEW, Kumasi, now AAMUSTED, as a Lecturer. Dr Offeh Gyimah pursued and completed his Ph.D. in Chemical and Process Engineering, focusing on the chemical and microwave-assisted approaches for the reclamation of metallic values from PCB waste, from University of Leeds, UK, in 2018. During his research at Leeds, a novel technique was developed for the strategic reclamation of metallic values namely gold, copper and nickel from the computer PCB finger wastes. Bmim[HSO4] ionic liquid was used to delaminate the PCB composite and to free embedded copper plates within the substrate, using microwave assistance. This research environment exposed him to a variety of material characterization tools such as SEM-EDX, XRD, PNA, UV-Vis, IR & Raman Spectroscopy.
The following disciplines are his primary research interests: Multi-principal element alloys processing and characterizations, CAD for manufacturability (DFMA), precious metals recovery and e-waste valorization, Welding Metallurgy and Additive Manufacturing
