Congratulations Stephen Akosah Darko

Stephen Akosah Darko is a graduating MPhil student from the Materials Engineering Department at KNUST. His research interests include energy storage materials, renewable energy, material synthesis, and characterisation.    

During his MPhil work, he repurposed waste soot through thermal treatment and synthesised annealed Manganese Cobaltite (MnCo2O4) nanomaterials to enhance the soot's supercapacitive performance.    

He developed a composite electrode material from these substances on nickel substrates and tested it for energy storage performance. His work demonstrated significant potential, with the material achieving up to 87% capacitance retention after 10,000 charge and discharge cycles.    

The KNUST Engineering Education Project (KEEP) has been instrumental in his academic success by providing financial support. He is very grateful for the support and encouragement received from the staff and management of KEEP.
