the main objective of this research was to synthesize and characterize gold-coated fe3o4 /sio2 nanoshells for clinical applications. magnetite nanoparticles (nps) were prepared via co-precipitation. the results showed that smaller particles can be synthesized by decreasing the naoh concentration, which in our case this corresponded to 35 nm by using 0.9 m of naoh at 750 rpm. the nps were then m...

an efficient method for purification of yard-glass shaped boron nitride nanotubes (yg-bnnts) fabricated via a chemical vapour reaction (cvr) route has been developed. impurities including carbon, boron nitride (bn), and fe species in the pristine yg-bnnt sample are removed by a combined physical and chemical procedure which involves ultrasonication, high temperature oxidation, hot-water washing...

In this paper we introduce the concept of $(1,2)^*$-sb-separated sets and $(1,2)^*$-soft b-connected spaces and prove some properties related to these break topics. Also we disscused the properties of $(1,2)^*$-soft b- compactness in soft bitopological space

Composite soft magnetic materials consist of magnetic particles in a non-magnetic matrix. The properties of such materials can be modelled using effective medium theory. Measurements have been made of the complex permeability of composites produced using ferrite powder and polyester resin. The success of various effective medium expressions in predicting the variation of complex permeability wi...

Mechanical cues such as extracellular matrix stiffness and movement have a major impact on cell differentiation and function. To replicate these biological features in vitro, soft substrata with tunable elasticity and the possibility for controlled surface translocation are desirable. Here we report on the use of ultra-soft (Young's modulus <100 kPa) PDMS-based magnetoactive elastomers (MAE) as...
