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...

recent investigations have been shown that inorganic nanomaterials including gold nanoparticles, nonporous and mesoporous silica nanoparticles, magneticnanoparticles, and quantum dots have shown great potential in bioimaging, targeted drug delivery, and cancer therapies. biocompatibility, ease of synthesis, and ease of surface functionalization are among the significant properties of nonporous ...
