Bruce Wessels wants to increase the data transmission connection on your computer. The Northwestern University professor of material science and engineering patented a device and material for integrated optic circuits. He says his thin-film electro-optical modulator provides a faster way to transmit information. Wessels uses a metal-organic molecular beam epitaxy apparatus for the thin-film deposition. In addition to the modulators, Wessels and associate professor Seng-Tiong Ho developed wave guides and optical amplifiers using ferroelectric material. They point out that bulk crystals used in optical circuits now have limits and their thin film is superior because it enables high-speed operations with low voltage for less expense. The researchers demonstrated that their thin-film modulators work at frequencies up to 20 gigahertz. SVT Associates is working with Wessels to develop and commercialize the technology.

Dow Chemical and several other companies have launched a program in Omaha, Neb. to divert about 36 tons of plastics from landfills in its first phase, and convert it into energy used for cement production.
Both traditional automation companies and startups are developing technologies to improve processes on the factory floor, while smart sensors and other IoT-related technologies are improving how products are handled during transport and across the supply chain.
