Magnetic nanoparticles are promising candidates for next generation high density magnetic data storage devices. Data storage requires precise control of the magnetic properties of materials, in which the magnetic anisotropy plays a dominant role. Since the total magneto-crystalline anisotropy energy scales with the particle volume, the storage density in media composed of individual nanoparticl...

The interactions between cells and nanomaterials at the nanoscale play a pivotal role in controlling cellular behavior ample evidence links cell intercommunication to nanomaterial size. However, little is known about effect of geometry on behavior. To elucidate this extend application cancer theranostics, we have engineered core–shell cobalt–gold nanoparticles with spherical (Co@Au NPs) ellipti...

Two materials were used, like graphene oxide nanosheets (GOn) and ferromagnetic nanoparticles (Fe3O4), to attenuate the electromagnetic (EM) properties in blend hybrid nanocomposites based on styrene-butadiene rubber (SBR) polyvinylidene difluoride (PVDF) as matrix. The rationale behind using either a ferroelectric or nanofillers Fe3O4 combination with intrinsically conducting (graphene oxide) ...

UNLABELLED Nanoparticles (NPs) are playing a progressively more significant role in multimodal and multifunctional molecular imaging. The agents like Superparamagnetic iron oxide (SPIO), manganese oxide (MnO), gold NPs/nanorods and quantum dots (QDs) possess specific properties like paramagnetism, superparamagnetism, surface plasmon resonance (SPR) and photoluminescence respectively. These spec...

Iron oxide exhibits fascinating physical properties especially in the nanometer range, not only from the standpoint of basic science, but also for a variety of engineering, particularly biomedical applications. For instance, Fe3O4 behaves as superparamagnetic as the particle size is reduced to a few nanometers in the single-domain region depending on the type of the material. The superparamagne...

The response of the structure of the M-type barium hexaferrite (BaFe12O19) to mechanical action through high-energy milling and its impact on the magnetic behaviour of the ferrite are investigated. Due to the ability of the (57)Fe Mössbauer spectroscopic technique to probe the environment of the Fe nuclei, a valuable insight on a local atomic scale into the mechanically induced changes in the h...
