Just touching it slightly with the tips of your fingers is enough. You can effortlessly write, navigate, open menu windows or rotate images on touchscreens. Within fractions of a second your touch is translated into control commands that a computer …
Chains of molecules known as conducting polymers are versatile materials that can work like electronic circuits. Potential uses include flat panel displays, solar panels, sensing devices and transistors, to name just a few. Their invention won three scientists the Nobel Prize in chemistry. But to make useful devices from conducting polymers requires a degree of chemical wizardry that often proves elusive. A Chicago chemistry professor has found a new and effective way around the problem.
