Opis:: The nuclear microprobe is a microanalytical tool capable of quantitative studies of elemental distribution at the ppm level with a spatial resolution of the order of 1μm. This sensitivity is adequate for most elements of interest, and the spatial resolution is acceptable for studies of elemental distribution in organs, tissues, and cells. The main techniques used in plant science are particle induced X-ray emission using protons, proton backscattering, scanning transmission ion microscopy, and particle induced gamma-ray emission. Specimen preparation is the most difficult part of analysis, and only cryotechniques are recommended presently for all types of microanalytical studies.

Opis:: Nanocomposite materials containing Fe₂O₃ and Gd₂O₃ nanoparticles with the same concentration were prepared by nanocasting method. At this procedure silica matrix serves as nanoreactor for growth of nanoparticles. Temperature and external dc field dependences of the magnetization both samples were compared. Composite containing Fe₂O₃ nanoparticles shows superparamagnetic behaviour with blocking temperature around 45 K. Otherwise, paramagnetic properties were observed for the sample with Gd₂O₃ (above 10 K). Additionally, due to free pores the silica matrix could serve as medium to increase the number of bonded water molecules. These properties together with appropriate magnetic characteristics make studied materials suitable for magnetic resonance imaging applications.
