"For electric conductivity, you need electrons to move
through a material," says Wally Cordes, a professor of chemistry and
biochemistry at the University of Arkansas. Cordes and his colleagues are
creating non-metal materials that conduct electricity. They bombard molecules
containing nitrogen-sulfur free radicals with X-rays in a process called x-ray
crystallography. The nitrogen sulfur free radicals have an unpaired electron
that provides the electrical conductivity. Electrons move from one molecule to
the next, but the material remains stable. Cordes is conducting ongoing research
for determining the optimum structure for electric conductivity. Contact Cordes

The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
