It is described for the first time synthesis and characterization of NiMn2O4 employing Mn ores from Amazon Region as starting material, instead using commercial reagents normally occurs in its process. Initially, an ore was transformed into a single product, octahedral layer (OL) manganese oxide with Ni2+ ions interlayer (Ni-OL-2), which used matrix to obtain by thermal decomposition. The follo...

NiMn2O4 (NMO) is a good alternative anode material for lithium-ion battery (LIB) application, due to its superior electrochemical activity. Current research shows that synthesis of NMO via citric acid-based combustion method envisaged application in the LIB, reversibility and rate performance. Phase purity crystallinity controlled by calcination at different temperatures, structural properties ...

NiMn₂O₄ prepared by conventional heating was irradiated with a microwave H-field using a single-mode cavity under air and magnetic properties of the microwave-irradiated material were investigated. X-ray diffraction and transmission electron microscopy demonstrated that the phase and microstructure are not affected by H-field irradiation. Measurements of the magnetization as a function of tempe...

Nanocrystalline nickel manganite (NiMn2O4) powder with a pure cubic spinel phase structure was synthesized via sol-gel combustion and characterized XRD, FT-IR, XPS SEM. The mixed sodium alginate gel to form nano-biocomposite gel, dried at room temperature thick film FT-IR DC resistance AC impedance of sensor test structures obtained by drop casting the onto interdigitated PdAg electrodes on an ...
