Author:Kebede, Mesfin A; Yannopoulos, SN; Sygellou, L; Ozoemena, KIDate:Oct 2017Oxygen-deficient pristine (LMNO) and microwave-treated LiMn1.5Ni0.5O4-d (LMNOmic) cathode materials have been synthesized with modified thermo-polymerization synthesis technique. The XRD, XPS, CV and charge/discharge voltage profile analysis ...Read more
Author:Sikhwivhilu, LM; Mpelane, S; Moloto, N; Ray, Suprakas SDate:Jan 2010The influence of the method of synthesis in the properties of the tubular structures derived from TiO2 was investigated using XRD, SEM and BET analysis. The use of microwave irradiation resulted in the formation of TiO2 tubes comprising anatase ...Read more
Author:Rohwer, Mark B; Modibedi, Remegia M; Ozoemena, KIDate:Feb 2015The impact of microwave irradiation on the structure and electrochemistry of monodispersed palladium nanoparticles is reported for the first time. When compared to the Pd that was not subjected to microwave treatment, the microwaved Pd ...Read more
Author:Jafta, CJ; Raju, Kumar; Mathe, Mahlanyane K; Manyala, N; Ozoemena, KIDate:Feb 2015A hybrid synthesis procedure, combining microwave irradiation and conventional annealing process, is described for the preparation of lithium-rich manganese-rich cathode materials, Li[Li0.2Mn0.54Ni0.13Co0.13]O2 (LMNC) and its aluminum-doped ...Read more
Author:Jafta, CJ; Mathe, Mahlanyane K; Manyala, N; Roos, WD; Ozoemena, KIDate:Aug 2013The LiMn1.5Ni0.5O4 spinel is an important lithium ion battery cathode material that has continued to receive major research attention because of its high operating voltage (∼4.8 V). This study interrogates the impact of microwave irradiation ...Read more
Author:Mavundla, SE; Malgas, GF; Motaung, DE; Iwuoha, EIDate:May 2012ZnO with a “flower-like” morphology was synthesized using a simple microwave assisted hydrothermal method and used as an acceptor material in hybrid solar cells. X-Ray diffraction and Raman Spectroscopy confirmed the formation of a highly ...Read more
