Magnetic fluids are stable colloidal systems of fine single-domain magnetic particles (for example Fe3O4, γ-Fe2O3, Co, MnFe2O4, etc.) that are suspended in liquid carrier such as water, mineral oil, damping oil, paraffin, kerosene and so on. The properties of magnetic fluids are well controlled by external magnetic field that gives broad possibilities for technical and biomedical applications. ...
High-fluorescent p-X-ferrites (XFe2O4; XFO; X = Fe, Cr, Mn, Co, or Ni) embedded in n-hematite (Fe2O3) surfaces were successfully fabricated via a facile bio-approach using Shewanella oneidensis MR-1. The results revealed that the X ions with high/low work functions modify the unpaired spin Fe2+-O2- orbitals in the XFe2O4 lattices to become localized paired spin orbitals at the bottom of conduct...
nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing ...
An efficient and reusable adsorbent, namely 3-mercaptopropionic acid modified tetraethyl orthosilicate (TEOS) grafted MnFe2O4 nanoparticles (MPA-TEOS-MnFe2O4 NPs) was synthesized and used for the extraction and preconcentration of trace amount of Al (III) and Cr (III) ions in water samples. MnFe2O4 NPs were prepared by chemical c...
long–term stability and oxidation resistance of aisi 439 ferritic stainless steel used as interconnects in solid oxide fuel cells can be improved by use of a protective coating. in this study the pack cementation method was employed to coat aisi 439 ferritic stainless steel with manganese. isothermal oxidation was conducted at 800 ºc for 200 hours in static air to investigate the role of coatin...
