Microcups Made of Nanopaper 144
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."

In order to finance such research as this, one must have something known as a 'large sum of money'.
Although there are many sources of these, the easiest one to use is known as the 'taxpayer'.
Most LSofM extracted from taxpayers goes to pensions, health, farm subsidies, bailing out airlines, making 'Mission Accomplished' banners, social welfare, corporate welfare, and defence.

Do you have anything to support this claim? At least in Europe, all (or nearly all) TP is made from recycled paper. Stiff paper is long-fibered, soft paper is short-fibered; fresh paper mass is long-fibered, recycled paper mass is short-fibered. It just makes economic sense.

To be honest I always thought you had the more sturdy greyish TP to be recycle and "economical", but they are alot more expensive.
Regular TP packaging -here in Belgium- rarely states it's manufactured out of recycled paper, only that its packaging is recyclable...
I don't manufacture TP myself, so I honestly wouldn't be able to say for certain. But I couldn't find a statement on the internet of someone who actually does.
