Another area which really fits well in the CFMC is the who arena of Buckypapers.  This first paper makes a very important point; "Relatively small concentrations of nanotubes can change a normally insulating polymer film to a transparent electrical conductor."  This has major market implications since  ITO (Indium/tin oxide) is a major component in touch-screen technology.  Needless to say, it has implications to conducting fibers, EMI shielding, etc.  The second paper is a bit of a refinement on the Buckypaper concept-a means of controlling pore size.  The team grew single crystals of polymers around the nanotubes which creates natural "spacers" to maintain a controlled distance between nanotubes.

An Advance Toward Ultra-Portable Electronic Devices Chemical Wiring and Soldering toward All-Molecule Electronic Circuitry" Journal of the American Chemical Society Scientists are reporting a key advance toward the long-awaited era of "single-molecule electronics," when common electronic circuits in computers, smart phones, audio players, and other devices may shrink to the size of a grain of sand. The breakthrough is a method for creating and attaching the tiny wires that will connect molecular components, reports a new study in the Journal of the American Chemical Society. Yuji Okawa and colleagues write that the "key to single-molecule electronics is connecting functional molecules to each other using conductive nanowires. This involves two issues: how to create conductive nanowires at designated positions, and how to ensure chemical bonding between the nanowires and functional molecules." That challenge has stymied many researchers, who have struggled to produce wires small enough to use in molecular circuits. The scientists now demonstrate a method that uses the tip of a scanning tunneling microscope to jump-start the formation of a molecule chain. The chain or "wire" spontaneously chemically bonds with other molecular components in the circuit under construction, a process that Okawa and colleagues dub "chemical soldering." The wiring method can be used to connect molecular switches, memory bits, and transistors. The scientists say their technique "will enable us to develop cheaper, higher-performance, and more ecological alternatives to conventional silicon-based devices." The authors acknowledge funding from the Japan Society for the Promotion of Science. SOURCE: American Chemical Society link

MIT Finds New Way to Control Conductivity: Reversible Control of Electrical and Thermal Properties Could Find Uses in Storage Systems "The process works because when the liquid freezes, the pressure of its forming crystal structure pushes the floating particles into closer contact, increasing their electrical and thermal conductance. When it melts, that pressure is relieved and the conductivity goes down. In their experiments, the researchers used a suspension that contained just 0.2 percent graphite flakes by volume. Such suspensions are remarkably stable: Particles remain suspended indefinitely in the liquid, as was shown by examining a container of the mixture three months after mixing. " Ref & story.

Novel Electrode for Flexible Thin-Film Solar Cells "If a solar cell made out of this material is bent, the electrode layers break and are no longer conductive.

Penn Research Advances Understanding of Lead Selenide Nanowires The key contribution of the team's work has to do with controlling the conductive properties of lead selenide nanowires in circuitry. Semiconductors come in two types, n and p, referring to the negative or positive charge they can carry. The ones that move electrons, which have a negative charge, are called "n-type." Their "p-type" counterparts don't move protons but rather the absence of an electron — a "hole" — which is the equivalent of moving a positive charge. The story.

Auto Industry Looks at Aluminum Wire to Save Weight We know copper wiring is heavy and has drawbacks. BMW is looking at aluminum wiring--see the referenced story. The US went through this phase with aluminum wiring in houses and industrial buildings—largely based on cost. The results were mixed at best. Auto makers are looking at cost, availability, and WEIGHT. This changes the equation somewhat. Data and experience proves that conductive fibers can perform like wire, but at a fraction of the weight...the future of Conductive Fibers looks better every day.
