Fluoride Nanoparticles

Due to the high atomic number of lutetium and the low phonon energy of the fluoride matrix, Lu-based fluoride nanoparticles doped with active lanthanide ions are potential candidates as bioprobes in both X-ray computed tomography and luminescent imaging. This paper shows a method for the fabrication of uniform, water-dispersible Eu3+:(H3O)Lu3F10 nanoparticles doped with different Eu contents. Their luminescent properties were studied by means of excitation and emission spectra as well as decay curves. The X-ray attenuation capacity of the phosphor showing the highest emission intensity was subsequently analyzed and compared with a commercial contrast agent. The results indicated that the 10% Eu3+-doped (H3O)Lu3F10 nanoparticles fabricated with the proposed polyol-based method are good candidates to be used as dual probes for luminescent imaging and X-ray computed tomography.

Foam Control

Algorithms for modeling the spatial structure of foam materials for the formation of projections in X-ray computed tomography and subsequent reconstruction of the internal structure of the samples are proposed. Algorithms are the basis of numerical models of the analyzed systems as applied to foam control. To demonstrate the capabilities of the developed algorithms, synograms and results of reconstruction of the internal structure of foam materials samples with variation of their parameters were obtained.
