the preparation of nanostructure type manganese oxide and cobalt oxide materials with the smallest particle size is reported here. the nanorod manganese oxide and cobalt oxide nanotube were prepared via a sol-gel reaction in reverse micelles from kmno4 and cocl2 with respectively source at room-temperature. the structure and surface morphology of the obtained manganese oxide were studied by mea...

this study was conducted to evaluate the relative bioavailability value of mn proteinate and mn oxide in broiler chicks. a total of 432 day-old cobb 500 commercial male broiler chicks were randomly distributed into nine treatments with eight replicate pens of six chicks each. in a completely randomized design experiment with a 2×4 factorial arrangement of two manganese sources (proteinate and r...

Manganese-nickel (Mn-Ni) oxide films were electrodeposited on a graphite sheet in a bath consisting of manganese acetate and nickel chloride, and the structural, morphological, and electrochemical properties of these films were investigated. The electrodeposited Mn-Ni oxide films had porous structures covered with nanofibers. The X-ray diffractometer pattern revealed the presence of separate ma...

Nano-sized particles of manganese oxides have been prepared by a very simple and cheap process using a decomposing aqueous solution of manganese nitrate at 100 °C. Scanning electron microscopy, transmission electron microscopy and X-ray diffraction spectrometry have been used to characterize the phase and the morphology of the manganese oxide. The nano-sized manganese oxide shows efficient cata...

the low bioavailability of zinc (zn) is in calcareous and saline soil, therefore the study of chemical forms and bioavailability of zn in these soils is necessary to estimate the potential availability. the objective of this study was to evaluate the effect of plant growth promoting rhizobacteria and mycorrhizae fungi inoculation on the chemical forms of zn in a calcareous soil at different sal...

Permanganate-Based Synthesis of Semiconducting Metal Oxide Nanoparticles in the Protein Ferritin Cameron Olsen Department of Physics and Astronomy, BYU Bachelor of Science This thesis investigates the reactions of Mn2+ and Co2+ with permanganate as a route for manganese and cobalt oxide nanoparticle synthesis in the protein ferritin. Permanganate serves as the electron acceptor and reacts with ...

Three manganese(II) N-oxide complexes have been synthesized from the reaction of manganese(II) chloride with either pyridine N-oxide (PNO), 2-methyl-pyridine N-oxide (2MePNO) or 3-methyl-pyridine N-oxide (3MePNO). The compounds were synthesized from methano-lic solutions of MnCl2·4H2O and the respective N-oxide, and subsequently characterized structurally by single-crystal X-ray diffraction. Th...

-The sorption properties of Co, Cu, Ni, and Ca were studied in a mixed mineral suspension of synthetic MnO2 and Wyoming montmofillonite. The distribution of the sorbed cations between the two solid phases was measured by indirect chemical fractionation with acidified NH2OH-HC1 and by direct X-ray spectroscopic analysis of mineral particles using electron microscopy. Electron microscope and NH2O...
