We report the formation of silicide by annealing a SiOx surface, with low coverage Eu doped Gd2O3 nanoparticles. The temperature required for removal native oxide from Si substrate decreases close to 200 °C in presence X-ray photoemission electron microscopy, low-energy microscopy and mirror are used monitor removal. Fragmentation nanoparticles is observed, layer gradually removed. migrates cle...

Surface-coating polymers contribute to nanoparticle-based magnetic resonance imaging (MRI) contrast agents because they can affect the relaxometric properties of nanoparticles. In this study, polyaspartic acid (PASA)-coated ultrasmall Gd2O3 nanoparticles with an average particle diameter 2.0 nm were synthesized using one-pot polyol method. The exhibited r1 and r2 19.1 = 53.7 s−1mM−1, respective...

For satellite propulsion, new material are developed to sustain harsh thermal and environmental conditions in the combustion chambers induced by development of “green” propellants less toxic than currently used hydrazine. In present study, hafnia-based materials with different amounts natures stabilisers (Lu2O3, Y2O3 Gd2O3) have been chosen for ceramic part system. Microstructures, Thermal Expa...
