The Columbi Eggs of Nanotechnology

The use of nanoscale materials to form larger size materials and devices is limited by many processing problems. These problems must be overcome to achieve many of the possible benefits of nanotechnology. In the context of finding seemingly simple solutions to complex problems, this paper looks at several of the barrier problems in nanoscale materials processing for different applications and proposes possible solutions to the problems. It is also noted that interdisciplinary and inter-institutional collaboration has made possible the progress reported in this paper.
