CoordenaÃÃo de AperfeiÃoamento de NÃvel Superior<br>The magnetic nanomaterials have attracted interest in many areas due to their unique properties and a wide range of applications. One of the most used nanoparticles is magnetite, formed of an oxide of Fe +2 and Fe +3 which has a high saturation magnetization and high surface area. These properties allow the immobilization of various molecules , such as surfactants , co - polymers , drugs and enzymes for application in biomedicine , food engineering , nanochips and biocatalysts .

Abstract:
[Truncated abstract] In the past decade, the synthesis of superparamagnetic iron oxide nanoparticles (SPIONs) has received considerable attention due to their potential applications in biomedical fields. However, success in size and shape control of the SPIONs has been mostly achieved through organic routes using large quantities of toxic or/and expensive precursors in organic reaction medium at high reaction temperature. This has limited the biomedical applications of SPIONs and therefore, development of a synthetic method under aqueous condition that is reproducible, scalable, environmentall

The growth of a magnesioferrite precipitate in iron doped (˜lOOOOppm wt.) magnesium oxide crystals, heat treated at 973K in oxygen, is studied with torque, magnetisation and magnetic resonance measurements.

Abstract:
The coloured noise formalism has long formed an important generalisation of the white noise limit assumed in many Langevin equations. The Langevin equation most typically applied to magnetic systems, namely the Landau-Lifshitz-Gilbert (LLG) equation makes use of the white noise approximation. The correct extension of the LLG model to the coloured noise is the Landau-Lifshitz-Miyazaki-Seki pair of Langevin equations. This pair of Langevin equations correctly incorporates a correlated damping term into the equa- tion of motion, constituting a realisation of the Fluctuation-Dissipation theorem fo

Abstract:
Depuis quelques années, notre laboratoire développe des nanoparticules lipidiques bicompartimentées originales produites par homogénéisation haute pression, un procédé transposable à grande échelle, à partir d’excipients pharmaceutiques validés par différentes pharmacopées (Eur., USP, JP). Ces particules appartiennent ainsi à la famille des nano-objets Janus puisqu’elles sont organisées en deux sous-structures juxtaposées : une moitié est constituée d’une gouttelette huileuse alors que l’autre moitié est composée d’une structure vésiculaire et renferme un cœur aqueux délimité par une bicouche

Abstract:
With the rapid development of nanotechnology, magnetic nanoparticles are currently being widely studied. It has long been known that the physico-chemical properties of magnetic nanoparticles can be vastly different from those of the corresponding bulk material. In particular, nanoparticles characteristics are: large surface-to-volume ratio, high surface reaction activity, high catalytic efficiency, and strong adsorption ability, which are helpful for the immobilization of desired biosensing molecules. The nanoparticles used in the present research project (called surface active maghemite nanop

This work deals with a preparation of superparamagnetic nano- and microparticles with hydrophilic surfaces for bioapplications. The wok is divided into three parts in consonance with experimentally solved problem. First part describes a choice and an optimalization of synthesis of iron oxides nanoparticles with appropriate toxicological, morphological and physico-chemical properties, which surface can be post synthetically modified. Maghemite - γ-Fe2O3 particles were prepared by consequent oxidation of mangnetite - Fe3O4 as an initial substance for a preparation of materials for diagnostics an

Abstract:
Superparamagnetic -Fe2O3 nanoparticles were synthesized by coprecipitation of ferric and ferrous salts with a base. Resulting nanoparticles were coated with shells, such as poly(N,N- dimethylacrylamide) (PDMAAm), neat and functionalized silica (SiO2 and SiO2-NH2), and polyaniline (PANI). PDMAAm shell was introduced by modification of iron oxide nanoparticle surface with an initiator and N,N-dimethylacrylamide was polymerized producing -Fe2O3&PDMAAm core-shell particles. In case of SiO2-NH2 shell, tetramethyl orthosilicate was used to yield -Fe2O3&SiO2 nanoparticles, which were subsequently
