Author:Raju, KumarDate:Jun 2020The search for new materials that can hold the heteroatoms viz., nitrogen, oxygen and phosphorus becomes crucial for robust energy storage and conversion devices. Recently, ammonium metal phosphates (NH4MPO4, M = Mn2+, Ni2+, Co2+, Fe2+, etc.) ...Read more
Author:Bello, A; Makgopa, K; Fabiane, M; Dodoo-Ahrin, D; Ozoemena, KI; Manyala, NDate:Oct 2013Few-layer graphene was synthesized on a nickel foam template by chemical vapor deposition. The resulting three-dimensional (3D) graphene was loaded with nickel oxide nanostructures using the successive ionic layer adsorption and reaction ...Read more
Author:Nwanya, AC; Obi, D; Ozoemena, Kenneth I; Osuji, RU; Awada, CDate:Apr 2016We describe the chemical synthesis of binderless and surfactant free CuO films for pseudocapacitive applications. Nanosheet-like and nanorod-like CuO films are deposited on indium tin oxide (ITO) substrates using the successive ionic layer ...Read more
Author:Melchior, SA; Raju, Kumar; Ike, IS; Erasmus, RM; Kabongo, G; Sigalas, L; Iyuke, SE; Ozoemena, KIDate:Feb 2018The energy storage performance of one of the lightest-known MXenes, Ti2CTx (MX) combined with carbon nanospheres (CNS) has been investigated as a symmetric electrode system in an aqueous electrolyte (1 M Li2SO4). The energy storage properties ...Read more
