Boland and colleagues showed for the first time that, in films of nanocrystalline copper just tens of nanometers thick, peaks and dips appear where misaligned grains meet. (sciencenews.org)
And because cellulose is the most abundant organic compound on the planet, nanopaper has the potential to be cheaper than more - exotic, expensive - to - produce nanomaterials such as carbon nanotubes, says John Simonsen, a physical chemist and nanocrystalline cellulose expert at Oregon State University in Corvallis.

In the type of copper the researchers studied, nanocrystalline copper, the grains are particularly small; each has around 1 million atoms. (sciencenews.org)
