PAPERS OF NOTE
Make
artificial spider silk and you have a way of collecting and channeling tiny
amounts of liquids.Directional Water Collection on Wetted Spider Silk, Nature
Put the right configuration of electrodes on a crystal surface and you can grow logic circuits made of different types of nanowires.
Direct Growth of Nanowire Logic Gates and Photovoltaic Devices, Nano Letters
Mix the right polymers and you can make a fine mesh of graphene ribbons suitable for blazingly fast computer circuits.
Graphene Nanomesh, Nature Nanotechnology
Mix the right polymers and you can make metal nanowires as narrow as 8 nanometers spaced as closely as 17 nanometers.

| "Physics
is to the rest of science what machine tools are to engineering. A
corollary is that science places power in our hands which can be used
for good or ill. Technology has been abused in this way throughout
the ages from gunpowder to atomic bombs." - John Pendry, Imperial College London |
