Europium-doped yttrium oxide (Eu-Y2O3) luminescent films have been produced directly from a solution precursor using a radio frequency (RF) plasma spray technique. Highly crystalline and luminescent films were grown on Si (100) and steel substrates by this process.
The fabrication of functional nanostructured materials requires practical approaches to self-assembly on multiple length scales. Here, the directed self-assembly of functionalized, luminescent nanoparticles at oil-water interface, followed by crosslinking of the associated ligands, affords robust membranes.
A soft cantilever beam, which can detect a very weak force, has been used by IRG1 researchers to uncover a striking property of cuprate superconductors: that trace supercurrents surrounding magnetic flux vortices persist for tens of degrees above the superconducting transition temperature Tc.
