Methods of Filtering Stable Quasicrystalline Nanoparticles

Quasicrystalline nanoparticles have great potential for industrial use and in the medical field. Some of these applications include hydrogen storage and a replacement for gold nanoparticles, which are used in the treatment of cancer. Our project involves the isolation and filtration of stable quasicrystalline nanoparticles to a size of less than five micrometers from an arc melted sample of Al$_{\mathrm{59}}$Cu$_{\mathrm{37}}$Fe$_{\mathrm{3}}$Si$_{\mathrm{1}}$. Successful filtration of less than five micrometers was completed using a SPI black membrane screen filter into a concentrated ethanol solution. It was then confirmed using a Tescan Vega 3 SEM. The composition of the nanoparticles was examined by Oxford, Aztec EDS.
