Mössbauer spectroscopy control of the preparation of citric- and mandelic acid functionalized nanomagnetites

The nature of our research is such that it has two equally important sides. One side deals with the preparation and characterization of nanoparticles - be that oxides, hydroxides, alloys or other forms of nanostructured matter - that may bear relevance in connection with plant metabolism. This side can well be classified as Materials Science. Enter this forum to access our related works and achievements.

When prepared in the nanoparticle form, magnetite can be prone to oxidation, which can lead to the formation of maghemite. Applying a molecular coating to the as prepared nanoparticles may have an effect on this process, influencing the magnetite/maghemite ratio and thereby the structural and magnetic properties of the nanoparticles. In this work we investigated the effects of coatings made of different (citric and mandelic) carboxylic acids on freshly synthesized magnetite nanoparticles.
