Developing the next generation of solar-powered robotic systems

Ran Dai earns NSF CAREER award to design unmanned vehicles for long-duration, high-efficiency missions Using renewable energy to power aerial and ground vehicles could change the way we handle aspects of environmental monitoring, search and rescue missions, surveillance, and agricultural practices. To navigate these sorts of dynamic environments, Ran Dai, an assistant professor in aerospace … Continue reading Developing the next generation of solar-powered robotic systems

New technology may bring new jobs

Jeff Fleenor (BSAerE’86) received state funding to help build a prototype large wood grinder. Fleenor’s idea also includes some technology he has patented which helps the grinder save on diesel fuel. Over time, his project has gained more support and is moving into the testing phase. Watch his story on WHO-TV.com.

Engineering receives Building Efficiency Award

At this year’s Sustainapalooza, the College of Engineering was recognized for the best reduction of energy use since 2008. Marston hall, which houses the college’s administrative offices and several classrooms, showed a cumulative decrease in British thermal unit (Btu) consumption of 61.84 percent over the three-year period. In 2008, Marston used 14,102,678,880 Btus of energy … Continue reading Engineering receives Building Efficiency Award

Chaudhary’s quest to improve organic solar cell efficiency gains traction with new approach and funding

An engineering professor’s plan to introduce ferroelectrics into the organic layers used to fabricate polymer solar cells may be the ingredient that could make the technology available to consumers in the very near future. Assistant Professor of Electrical and Computer Engineering Sumit Chaudhary says ferroelectric materials, which act like dipoles with a positive and negative … Continue reading Chaudhary’s quest to improve organic solar cell efficiency gains traction with new approach and funding

Students to process waste vegetable oil from ISU Dining to fuel CyRide bus

Some Iowa State University students are serious about getting their campus community “on the bus” when it comes to green living. And they hope to pick up some other Ames residents along the way. That’s at least the plan, according to David Correll, a Ph.D. student in Iowa State’s College of Business and co-founder and … Continue reading Students to process waste vegetable oil from ISU Dining to fuel CyRide bus

Iowa State engineer developing technology to enhance battery life in portable devices

Soldiers carrying sophisticated communication and navigation devices into the field have the same battery headaches as civilians working their smart phones at the airport. One way to assure that soldiers have an adequate power supply for their electronic tools has been to strap extra batteries to their backs. But Ayman Fayed, an Iowa State assistant … Continue reading Iowa State engineer developing technology to enhance battery life in portable devices

More than lab work

Two themes that I’ve emphasized as dean are collaboration and sustainability. While it’s not difficult to imagine that those two concepts are closely related, to see them resonate well in a single project is truly gratifying. The project, in this case, is a $2 million renovation of research labs in the 1964 wing of Sweeney … Continue reading More than lab work

Magnetic refrigeration cleaner and more efficient

A new cooling technology — cleaner, more efficient, and with the potential to have broad-ranging effects on global warming — is just around the corner, according to Karl A. Gschneidner Jr., Anson Marston Distinguished Professor in the Department of Materials Science and Engineering, and senior scientist at the U.S. Department of Energy’s Ames Laboratory. After … Continue reading Magnetic refrigeration cleaner and more efficient

Chaudhary fabricates more efficient polymer solar cells

Researchers from Iowa State University and the Ames Laboratory have developed a process capable of producing a thin and uniform light-absorbing layer on textured substrates that improves the efficiency of polymer solar cells by increasing light absorption. “Our technology efficiently utilizes the light trapping scheme,” said Sumit Chaudhary, an Iowa State assistant professor of electrical … Continue reading Chaudhary fabricates more efficient polymer solar cells
