a feasible and fast method to fabricate hydrogen peroxide sensor was investigated by graphene-manganase nanocomposite carbone paste electrode. in the present work, in first step, the graphene was synthesized by chemical method and in second step, manganese oxide nanoparticle was doped on graphene. graphene-manganase nanocomposite was characterized by ftir and sem. the nanocomposite shows a high...

Polynuclear manganese complexes are used as precursors for the synthesis of manganese oxide nanoparticles (MnO NPs). Altering the thermal decomposition conditions can shift the nanoparticle product from spherical, thermodynamically-driven NPs to unusual, kinetically-controlled octapod structures. The resulting increased surface area profoundly alters the NP's surface-dependent magnetism and may...

This paper investigates the comproportionation reaction of MnII with [Formula: see text] as a route for manganese oxide nanoparticle synthesis in the protein ferritin. We report that [Formula: see text] serves as the electron acceptor and reacts with MnII in the presence of apoferritin to form manganese oxide cores inside the protein shell. Manganese loading into ferritin was studied under acid...

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 ...

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...

Rat glioma cells were labeled using electroporation with either manganese oxide (MnO) or superparamagnetic iron oxide (SPIO) nanoparticles. The viability and proliferation of SPIO-labeled cells (1.9 mg Fe/ml) or cells electroporated with a low dose of MnO (100 microg Mn/ml) was not significantly different from unlabeled cells; a higher MnO dose (785 microg Mn/ml) was found to be toxic. The cell...

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...
