Magnetic fluids are stable colloidal suspensions of ferromagnetic nano-particles (of size 10-20 nm) in a nonmagnetic liquid carrier. An initially uniform particle distribution in the carrier becomes spatially inhomogeneous in nonuniform magnetic fields. Motion of particles in magnetic fluids under the action of magnetic fields is of particular interest for contemporary mathematical and numerica...

Objective(s): For cancer cells, an efficient and selective drug delivery vehicle can remarkably improve therapeutic approaches. This paper focuses on the synthesis and characterization of magnetic MnFe2O4 NPs and their incorporation in a dual temperature and pH-responsive polymer, which can serve as an efficient drug carrier. Materials and Methods: MnFe2O4 NPs were synthesized by chemical co-pr...

Uniform carbon nano test tubes including magnetic metal particles inside their one-dimensional cavities were synthesized by the template method. The "as synthesized" metal-filled test tubes (35 nm in diameter and 1400 nm in length) were dispersible in ethanol, but not in water. To improve the water-dispersibility of the test tubes, their surface was treated with hydrogen peroxide and, as a resu...

in order to study the effects of magnetic field, silver nano particles and micronutrient fertilizers on sugar beet, an experiment was conducted at razavi research and technology institute, mashhad, iran. experiment carried out with seven treatments based on randomized complete block design with three replications. treatments included (t1) magnetic field and silver nano particles + kemira fertil...

PURPOSE We describe the synthesis and use of an efficient nano carrier molecule for retinal delivery of a nano chitosan peptide that has potential application for treating age-related macular degeneration (AMD). We chose serine-threonine-tyrosine as the peptide sequence because it is well known to act as a transduction signaling agent within and between retinal pigmented epithelium cells. MET...
