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.

For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
Green energy is being billed as a way to make communities that are energy deprived more self-sustaining. So it makes sense to use natural materials to create devices that harvest this type of energy. That’s the idea behind a hybrid wind/solar energy harvester made of bamboo that’s been developed by UVM researchers.
