چکیده
Magnetite (Fe304) nanoparticles stabilised by sulfonatocalixarene macrocycles are readily accessible by a rapid in situ co-precipitation, and exhibit ferro-fluidic and superparamagnetic behaviour.

Comparative structure analysis of non-polar organic ferrofluids stabilized by saturated mono-carboxylic acids.
The structure of ferrofluids (magnetite in decahydronaphtalene) stabilized with saturated mono-carboxylic acids of different chain lengths (lauric, myristic, palmitic and stearic acids) is studied by means of magnetization analysis and small-angle neutron scattering. It is shown that in case of saturated acid surfactants, magnetite nanoparticles are dispersed in the carrier approximately with t...
متن کاملInvestigation of NMR Shielding Tensors of Para-Sulfonato-calix 141 arene Complexation with some of Alkali metal atoms
Calixarenes are a readily available and important class of macrocycles in supramolecularchemistry. Calixarenes have generated considerable interest due to their basket shaped structureand as useful building blocks to synthesize selective receptors for the guest species, notably alkali,alkaline earth, lanthanide and transition metal cations. In this work studied on the complexingproperties of a ...
متن کاملA short review on Ferrofluids surface modification by natural and biocompatible polymers
This paper provides an overview of how the surface properties of ferromagnetic nanoparticles dispersed in fluids is modified by natural and biocompatible polymers. Among common magnetic nanoparticles, magnetite (Fe3O4) and maghemite (g-Fe203) are popular candidates because of their biocompatibility. Natural polymeric coating materials are the most commonly used biocompatible magnetic nanopartic...
متن کاملSubmicron Structure in Biocompatible Ferrofluids
This paper was intended as a comparative study between the microstructural features of two water-ferrofluids intended for biological applications. In both cases the ferrophase was prepared by auto-catalytic reaction between ferrous and ferric salts resulted in magnetite and some maghemite precipitates. The difference is given by the stabilizer molecule: tetramethyl ammonium hydroxide and, respe...
متن کاملTwo and Three Dimensional Monte Carlo Simulation of Magnetite Nanoparticle Based Ferrofluids
We have simulated a magnetite nanoparticle based ferrofluid using Monte Carlo method. Two and three dimensional Monte Carlo simulations have been done using parallel computing technique. The aggregation and rearrangement of nanoparticles embedded in a liquid carrier have been studied in various particle volume fractions. Our simulation results are in complete agreement with the reported experim...
