Bending and wrinkling as competing relaxation pathways for strained free-hanging films 
iMechanica | by Peter Cendula | Thu, Oct 8
iMechanica is the #2 Blogger for Nanotechnology
A thin film subject to compressive strain can either bend (for large strain gradient) or wrinkle (for small strain gradient). The bending is traditionally used in thermostats (bimetal stripes), but couple of years ago, it was extended to the nanoscale thin films which can bend and roll-...

Opinion: Complex Nanotube Circuits
1) Grow the nanotubes on a separate substrate, then stamp them onto the circuit. This lets the circuit stay at low temperatures. By contrast, nanotubes are single, precise molecules being assembled to build up useful larger systems. This is a lot closer to the original meaning of the word.
