Self-supported Mn3O4 patterns of aligned nanorods and nanotubes were synthesized through a bi-directional-bi-dimensionality growth model by using sodium gluconate and urea as additives under mild hydrothermal conditions without the use of any substrates. In one direction, Mn3O4 grows to form one-dimensional nanorods or nanotubes, while in the other direction Mn3O4 grows into two-dimensional nan...

For manganese oxides with low manganese oxidation states, such as MnO or Mn3O4, the electrochemical oxidation during potential cycling is critical to achieve high supercapacitor performance. In this work, dense Mn3O4 thin films are prepared by pulsed laser deposition. An electrochemical lithiation/delithiation process is applied to the Mn3O4 thin film, which leads to a nanoporous structure of t...

Manganese-deficient individuals have decreased manganese elimination. This observation has prompted suggestions that relative manganese deficiency may increase the risk for manganese neurotoxicity following inhalation exposure. The objective of this study was to determine whether dietary manganese intake influences the pharmacokinetics of inhaled manganese tetroxide (Mn3O4). Postnatal day (PND)...

Cerium–manganese mixed oxides with compositions of Ce0.5Mn0.5O1.75 and Ce0.8Mn0.2O1.9 were prepared by the citric-acid (Pechini) method and their catalytic properties were compared to CeO2 and Mn2O3. The mixed oxides exhibited higher specific rates than either CeO2 or Mn2O3 for oxidation of both methane and nbutane. While XRD measurements of the mixed oxides suggested that the materials had pri...

Hybrid nanomaterials based on manganese, cobalt, and lanthanum oxides of different morphology phase compositions were prepared using a facile single-step ultrasonic spray pyrolysis (USP) process tested as electrocatalysts for oxygen reduction reaction (ORR). The structural morphological characterizations completed by XRD SEM-EDS. Electrochemical performance was characterized cyclic voltammetry ...

Thin films of physical mixture Hausmannite Mn3O4 and lithium (Li) are synthesized by spray pyrolysis technique. Structural, morphological, optical, electrical, wettability, photocatalytic properties have been investigated. X-ray diffraction (XRD) Raman spectra, Scanning electron microscope (SEM) images, electrical measurements show that Li nanoparticles formed both on top surface the film insid...

A composite electrode of carbon nanotube CNT@Mn3O4 nanocable was successfully synthesized via direct electrophoretic deposition onto a copper foil, followed by calcination. By uniformly depositing Mn3O4 nanoparticles on CNTs, structure can be formed, where the CNT acts as “highway” for electrons and ions to facilitate fast transportation. Moreover, capacitive energy storage processes play cruci...
