Michael Ward is creating crystals that may eventually improve lasers and optical switching devices. The University of Minnesota researcher and professor of materials science designs solid-state structures. The crystals make possible the changing of red light to green or blue. Ward's crystals could, for example, be an enabler of blue light lasers. He points out that blue lasers, although difficult to build, are desirable for telecommunications applications because information transmits faster at blue light's higher frequencies and shorter wavelengths. "What we are doing is crystal engineering," says Ward. "We are able to design a crystal with a polar structure," he adds. Because they are polar, the crystals double the frequency of light. In optical switching, Ward's crystals function as transmitters for passing information. "There are other materials that can do what our crystals do, but they don't have the thermal robustness that these crystals have," says Ward.

Lithium-ion battery prices will drop rapidly over the next 10 years, setting the stage for plug-in vehicles to reach 5%-10% of total automotive sales by the mid- to late-2020s, according to a new study.
Two researchers from Cornell University have won a $100,000 grant from NASA to continue work to develop an energy-harvesting robotic eel the space agency aims to use to explore oceans on one of the moons of Jupiter.
Is the factory smarter than it used to be? From recent buzzwords, you’d think we’ve entered a new dimension in industrial plants, where robots run all physical functions wirelessly and humans do little more than program ever more capable robotics. Some of that is actually true, but it’s been true for a while.
A recent Design News-exclusive study proves that engineering professionals are at the very forefront of this push into the future and making direct financial, performance, and value impact on their organizations by being personally involved or final decision-makers on automation solution and component choices.
