Carbyne morphs when stretched
Houston TX (SPX) Jul 28, 2014 - Applying just the right amount of tension to a chain of carbon atoms can turn it from a metallic conductor to an insulator, according to Rice University scientists. Stretching the material known as carbyne - a hard-to-make, one-dimensional chain of carbon atoms - by just 3 percent can begin to change its properties in ways that engineers might find useful for mechanically activated nanoscale ele ... more
