Paper of Note
Inkjetting prints fast, flexible circuits
July 29, 2011
Spray the right cocktail through an inkjet printhead, and you can print single-crystal semiconductors to make fast transistors for flexible surfaces.
Inkjet printing of single-crystal films, Nature

Paper of Note
Nanotube-protein pair smells
July 29, 2011
Connect olfactory proteins to carbon nanotubes and you have the makings of a lifelike artificial nose.
Biomimetic Chemical Sensors Using Nanoelectronic Readout of Olfactory Receptor Proteins, ACS Nano

Paper of Note
Batteries get see-through treatment
July 25, 2011
Fill a flexible, transparent material’s microscopic channels with the stuff of battery electrodes, and you have a bendable, see-through battery. Pair this battery with see-through circuits, and you can make all manner of transparent gadgets.
Transparent lithium-ion batteries, Proceedings of the National Academy Of Sciences

Paper of Note
Chemistry promises tomorrow’s computer circuits
July 25, 2011
Mix up a batch of the right super-size molecules and you get networks of intersecting nanoscale wires. The technique could be used to grow tomorrow’s computer circuits.
Self-assembly of supramolecular wires and cross-junctions and efficient electron tunnelling across them, Chemical Science

Paper of Note
Carbon nanotube materials made easier
July 22, 2011
Confine the right chemical reaction to to the right places on carbon nanotubes, and you can keep the nanotubes from clumping together while preserving the tubes’ useful electrical and optical properties. This makes it easier to manufacture inexpensive, transparent electronics, including flexible displays.
Confined propagation of covalent chemical reactions on single-walled carbon nanotubes, Nature Communications

"In most areas of science and technology, the origins of new breakthroughs can still be found in the work of a small number of people -- or even a single person -- working at their own pace on their own questions, pursuing things that interest them. "
- Jon Kleinberg, Cornell University

"Funding, of course, enables discoveries but does not guarantee they will occur. Lack of funding can almost certainly guarantee that discoveries will not be made."
- Ronald Arkin, Georgia Institute of Technology

"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
