Increasing interests have been paid to nanofluids because of the intriguing heat transfer enhancement performances presented by this kind of promising heat transfer media. We produced a series of nanofluids and measured their thermal conductivities. In this article, we discussed the measurements and the enhancements of the thermal conductivity of a variety of nanofluids. The base fluids used in...

The controlled release of Salicylic Acid (SA) influences the concentration and collateral effects drug. This refers to matrix in which SA is incorporated. Among matrices, Fe3O4 nanoparticles (NPs) stand out, for transporting drugs specific sites. functionalization by bovine serum albumin (BSA) can improve colloidal chemical stability, addition increasing interactions with drugs. Thus, understan...

Recently, the use of superparamagnetic iron oxide nanoparticles (SPIONS) as a new and promising source of iron in agriculture has been suggested that further investigation is needed before extensive field use. In a greenhouse experiment, the effect of coated magnetite nanoparticles with humic acid (Fe3O4/HA NPs) was investigated on iron deficiency chlorosis and photosynthesis efficiency compare...

In this study, a simple and fast magnetic dispersive solid phase extraction methodology was developed G@Fe3O4/Fe/Ag nanoparticles for preconcentration and determine of phenolic compounds in water samples. The sorbent was characterized by assorted characterization method. The effects of diverse factor on the extraction process were studied thoroughly via design of experiment and desirability fun...

In the last decade, iron oxide nanoparticles (NPs)—known as super-paramagnetic iron oxide nanoparticles (SPION)—have received significant attention due to their applicability in a variety of domains. In the biomedical field, iron oxide nanoparticles are very promising as drug-delivery systems, magneticresonance-imaging contrast enhancers (clinical diagnosis), inflammation-responsive or anti-can...

Multifunctional Fe3O4/Eu(DBM)3phen/PVP ((DBM: dibenzoylmethane, phen: 1,10-phenanthroline, PVP: polyvinyl pyrrolidone) microfibers were constructed by simple electrospinning process. The structure and morphology of the characterized X-ray diffraction (XRD), scanning electron microscopy (SEM) transmission (TEM) images. diameters pure PVP doped only with Fe3O4 nanoparticles (NPs) uniformly distri...

magnetic nanoparticles are the good choice for using in mri as the contrast agent. iron oxide particles such as magnetite (fe3o4) or its oxidized form maghemite (γ-fe2o3) are the most commonly employed in biomedical applications. in this study, we synthesized and optimized the preparation of chitosan manganese-ferrite nanoparticles (cmn-fe nps) and evaluated its ability for the mice macrophage ...

This work presents a rapid and facile way to access the cell wall of wood with magnetic nanoparticles (NPs), providing insights into method modification prepare hybrid bio-based functional materials. Diffusion-driven infiltration Scots pine (Pinus sylvestris L.) sapwood was achieved using colloidal Fe3O4 nanoparticles. Optical microscopy, scanning electron microscopy/energy-dispersive X-ray spe...

Hydrophobic magnetic nanoparticles (NPs) consisting of undecanoate-capped magnetite (Fe3O4, average diameter ca. 5 nm) are used to control quantized electron transfer to surface-confined redox units and metal NPs. A two-phase system consisting of an aqueous electrolyte solution and a toluene phase that includes the suspended undecanoatecapped magnetic NPs is used to control the interfacial prop...
