"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

Last year at Hannover Fair, lots of people were talking about Industry 4.0. This is a concept that seems to have a different name in every region. I’ve been referring to it as the Industrial Internet of Things (IIoT), not to be confused with the plain old Internet of Things (IoT). Others refer to it as the Connected Industry, the smart factory concept, M2M, data extraction, and so on.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
