  • Intense competition exists in the realm of research and development in nanotechnology. The government of Japan, one of the countries most advanced in this field, has been actively promoting this form of R&D in cooperation with industrial and academic circles. The hope is that success in nanotechnology will also revitalize Japan's economy. Here, we outline the current status of national projects and future trends of nanotechnology in Japan.

  • Although the advent of organic electronics promises the development of such futuristic applications as electronic paper, the limited resolution with which these materials can be patterned is hampering the progress. But the way forward may now have been found by investigating how these materials dewet from submicrometre hydrophobic lines patterned on a surface.
