Bello, Abdulhakeem; Barzegar, Farshad; Momodu, Damilola Y.; Dangbegnon, Julien K.; Taghizadeh, Fatemeh; Fabiane, Mopeli; Manyala, Ncholu I. (Elsevier, 2015-01)We present the electrochemical results of highly porous and interconnected carbon material by activation of graphene foam/polyvinyl alcohol-formaldehyde composite material designated as GF/PVA-F. Asymmetric supercapacitor ...

Barzegar, Farshad; Momodu, Damilola Y.; Taghizadeh, Fatemeh; Auret, Francois Danie; Manyala, Ncholu I.; Xia, Xiaohua (Elsevier, 2019-02)This work presents the effect of electron irradiation on the full symmetric cell using the pure polymer base AC material and irradiation on the full cell was analyzed for different exposure times. An improvement of the ...

Bello, Abdulhakeem; Fashedemi, Omobosede O.; Momodu, Damilola Y.; Barzegar, Farshad; Masikhwa, T.M. (Tshifhiwa); Madito, M.J. (Moshawe); Taghizadeh, Fatemeh; Dangbegnon, Julien K.; Manyala, Ncholu I. (Elsevier, 2015-08)A microwave irradiation method has been used to prepare mixed nickel cobalt sulfide (NixCoyS4) nanosheets with different stoichiometric composition as electrodes for electrochemical capacitors. This study has been ...

Barzegar, Farshad; Bello, Abdulhakeem; Fabiane, Mopeli; Khamlich, Saleh; Momodu, Damilola Y.; Taghizadeh, Fatemeh; Dangbegnon, Julien K.; Manyala, Ncholu I. (Elsevier, 2015-02)We report on the synthesis and characterization of electrospun polyvinyl alcohol (PVA)/graphene nanofibers. The samples produced were characterized by Raman spectroscopy for structural and defect density analysis, scanning ...

Bello, Abdulhakeem; Barzegar, Farshad; Momodu, Damilola Y.; Dangbegnon, Julien K.; Taghizadeh, Fatemeh; Manyala, Ncholu I. (Elsevier, 2015-01)The construction and design of novel porous carbons for electric double-layer capacitors (EDLCs) application to meet the increasing demand and supply of energy is eminent. This is important because the pore volume ...
