Abstract In the present study, a modified duplex melting process was set up so as to be able produce an EN-GJL-150 gray cast iron from local manganese-rich pig iron. A descriptive statistics showed average Mn and Si content in raw material such that: % = 2.457±0.133 0.682±0.088. The demanganization run monitored cascade of two industrial-scale furnaces: rotary kiln electric arc furnace. perform...

Magnetic and fluorescent hydroxyapatite nanoparticles were synthesised using Al(OH)3-stabilised MnFe2O4 or Fe3O4 nanoparticles as precursors. They were readily and efficiently radiolabelled with (18)F. Bisphosphonate polyethylene glycol polymers were utilised to endow the nanoparticles with excellent colloidal stability in water and to incorporate cyclam for high affinity labelling with (64)Cu.

The photomagnetic effect has been investigated in a Fez. loLi0.45Mn0.4504 ferrite by looking at the variations of the permeability under light irradiation. It is shown that the time constact of the phenomenon increases with temperature, resulting in a negative activation energy w = 1.3 x 10-2 eV. The explanation of the results is grounded on the photo-induced electron migration between Mn2+ and...

In this work, lamellar MnFe2O4 was successfully planted on a wood surface through the association of hydrogen bonds via the one-pot hydrothermal method. Simultaneously, the fluoroalkylsilane (FAS-17) on the surface of the MnFe2O4 layer formed long-chain or network macromolecules through a poly-condensation process and provided a lower surface energy on the wood surface. The MnFe2O4/wood composi...

Co-Zn ferrite and BaM ferrite films were deposited on silicon wafer disks with thermally oxidized surface layer without annealing process, and their readlwrite characteristics in contact mode have been investigated by using a MIG and Mn-Zn ferrite head with gap length of 0.2-0.4 pm. The highest linear recording density D50 of Co-Zn ferrite and Ba ferrite films were 105 and 190 WRPI, respectivel...

(*) Corresponding Author e-mail: [email protected] ABSTRACT: Magnetic nanoparticles are the good choice for using in MRI as the contrast agent. Iron oxide particles such as magnetite (Fe3O4) or its oxidized form maghemite (γ-Fe2O3) are the most commonly employed in biomedical applications. In this study, we synthesized and optimized the preparation of chitosan manganese-ferrite nanoparticles...
