Applicable anode based on Co3O4–SrCO3 heterostructure nanorods-incorporated CNFs with low-onset potential for DUFCs
Ghouri, Zafar Khan; Elsaid, Khaled; Al-Meer, Saeed; Barakat, Nasser A.M. ( Springer , 2017 , Article)Besides the high-current density, lower onset potential of urea electrooxidation is key parameter which influences the direct urea fuel cell performance. In the present article, low-onset potential has been reported for ... -
Capacitance of MnO2 Micro-Flowers Decorated CNFs in Alkaline Electrolyte and Its Bi-Functional Electrocatalytic Activity toward Hydrazine Oxidation
Ji, Seong-Min; Ghouri, Zafar Khan; Elsaid, Khaled; Ko, Yo Han; Al-Meer, Saeed; Ahmad, M.I.; Son, Dong Ick; Kim, Hak Yong... more authors ... less authors ( ESG , 2017 , Article)Well-dispersed MnO2 micro-flowers were grown directly on carbon nanofibers via a simple hydrothermal technique without any template. Structure and morphology were characterized by X-ray diffraction (XRD) and field-emission ... -
Critical Behavior of La0.8Ca0.2Mn1−xCoxO3 Perovskite (0.1 ≤ x ≤ 0.3)
Turki, Dorra; Ghouri, Zafar Khan; Al-Meer, Saeed; Elsaid, Khaled; Ahmad, M.I.; Easa, Ahmed; Remenyi, Gyorgy; Mahmood, Sami; Hlil, El Kebir; Ellouze, Mohamed; Elhalouani, Foued... more authors ... less authors ( MDPI , 2017 , Article)The critical properties of La0.8Ca0.2Mn1−xCoxO3 (x = 0, 0.1, 0.2 and 0.3) compounds were investigated by analysis of the magnetic measurements in the vicinity of their critical temperature. Arrott plots revealed that the ... -
