Roland Piquepaille writes "Researchers at the University of Arkansas have created long nanowires with titanium dioxide and assembled them into pieces of 'nanopaper.' This flexible paper can fold into 3D nanostructures such as tubes, bowls or cups. This kind of nanopaper could soon be used for applications such as bacteria filters, decomposition of pollutants and chemical warfare agents. But first the University needs to find industrial partners. Read more for additional details and some pictures of these microcups."
