alzheimer's disease (ad) is a progressive neurodegenerative disease characterized by memory and cognitive dysfunction due to neuronal cell loss in higher brain centers. senile plaques containing amyloid β (aβ) are associated with this disease as well as a reduction in cholinergic neuron numbers. tacrine is a reversible cholinesterase inhibitor in clinical use to treat moderate forms of ad. chit...

Cobalt ferrite nanoparticles (CoFe2O4) are well known for some distinctive characteristics such as high magnetic permeability and coercive force, good saturation magnetization, excellent physical, and chemical stability, which make them so attractive for magnetic storage, magnetic resonance imaging (MRI), drug delivery, optical-magnetic equipment, radar absorbing materials...

In this paper, the effect of magnetic field on the morphology, structure and magnetic properties of electrodeposited FeCu/Cu thin films was investigated. The films were deposited on Au2PdAg/glass substrates using electrodeposition technique in potentiostatic control. The magnetic fields of 5000 and 7000 Oe were applied on deposition bath during deposition. Two series of thin films were prepared...

the entanglement at zero-temperature is studied in a two-qubit xz spin-1/2 chain model in anexternal magnetic field which is applied in the z direction. we have obtained an analytical relation forthe effect of the external magnetic field on the concurrence. it is shown that the ground state of thesystem depends on the strength of exchange coupling. we have shown that the analytical relation oft...

in this work, we investigated synthesis, magnetic properties of silica coated metal ferrite, (cofe2o4)/sio2 and manganese doped cobalt ferrite nanoparticles (mnxco1-xfe2o4 with x= 0.02, 0.04 and 0.06)/sio2 for possible biomedical application. all the ferrites nanoparticles were prepared by co-precipitation method using fecl3.6h2o, cocl2.6h2o and mncl2.2h2o as precursors, and were silica coated ...
