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 ... -
Synthesis and Physicochemical Studies of Perovskite Manganite La0.8Ca0.2Nn1−xCoxO3 (0 ≤ x ≤ 0.3)
Turki, D.; Ghouri, Zafar Khan; Al-Meer, Saeed; Elsaid, Khaled; Ahmad, M.I.; Easa, Ahmed; Ellouze, M.; Hlil, E.K.... more authors ... less authors ( The Korean Magnetics Society , 2017 , Article)The physicochemical properties of La0.8Ca0.2Mn1−xCoxO3 nanopowders as a function of Co content (x) have been investigated. La0.8Ca0.2Mn1−xCoxO3 nanopowders were synthesized by sol-gel method and morphologically and ... -
ZnO@C (core@shell) microspheres derived from spent coffee grounds as applicable non-precious electrode material for DMFCs
Ghouri, Zafar Khan; Al-Meer, Saeed; Barakat, Nasser A. M.; Kim, Hak Yong ( Nature Publishing Group , 2017 , Article)Although numerous reports have introduced non precious electrocatalysts for methanol oxidation, most of those studies did not consider the corresponding high onset potential which restricts utilization in real fuel cells. ...
