Increases versatility of conducting polymers
A powerful one-step, "chain growth" method should make it easier to design and synthesize a variety of highly conductive polymers for different research and commercial applications, according to a presentation by the methods developer, Carnegie Mellon University chemist Richard McCullough. McCullough, dean of the Mellon College of Science and professor of chemistry, is reporting his research Tuesday, March 30, at the 227th annual meeting of the American Chemical Society in Anaheim, Calif. (POLY 360, Plaza B).
McCullough has harnessed the chain-growth method to increase the versatility of the conducting polymers, called regioregular polythiophenes. This new method allows scientists to "cap" each conducting polymer with chemical groups that link to other structural polymers (Figure 1). With this research, funded by the National Science Foundation, researchers can form highly conductive nanowire sheets within polymer blocks (Figure 2) or create a plethora of new conducting polymers.

Researchers led by Francesca Ferlaino from the University of Innsbruck and the Austrian Academy of Sciences report in Physical Review X on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.
Supersolidity is a paradoxical state where the matter is both crystallized and superfluid. Predicted 50 years ago, such a counter-intuitive phase, featuring...
