Iowa State engineer models heart valves, wind turbines for better designs, performance

Three thin leaflets blew open and blood blasted through an artificial heart valve, the center stream firing reds and yellows, the colors indicating a flow speed up to 125 centimeters per second. When the leaflets slammed shut, the flow turned to light blue eddies, indicating blood flow had nearly stopped.

Iowa State engineers build cyber security testbed to help protect the power grid

It’s easy to think of the electrical grid as the power plants, the high voltage lines, the transmission towers, the substations and all the low-voltage distribution lines that bring power to our homes and businesses.An attack on that grid would involve getting out and cutting lines or dropping towers.

Three from ECpE named IEEE Fellows

Election of Chen, Rover, and Wang gives the ECpE Department 18 IEEE Fellows Three faculty members from the Department of Electrical and Computer Engineering at Iowa State University were elected fellows of the Institute of Electrical and Electronics Engineers (IEEE) for 2016. Degang Chen, Jerry R. Junkins Chair; Diane Rover, University Professor; and Zhengdao Wang, [Continue Reading…]

Iowa State, Ames Laboratory engineer developing materials for tissue engineering, vaccines

Surya Mallapragada believes in the power and potential of bio- and bio-inspired materials to improve human health. She’s been researching the materials and how they can solve biomedical problems for nearly two decades. And there are good reasons for sticking with the studies.

Iowa State University awarded $3 million from ARPA-E for transformational energy technology

Researchers in the College of Engineering work to create a low-cost, safe and efficient sodium-based battery While lithium-ion batteries have proven their worth in storing energy on a smaller scale, Steve W. Martin says an alternative solution is necessary for storing large amounts of energy, like the gigawatts of wind energy now being harvested from [Continue Reading…]

Creating a power source for unmanned micro underwater vehicles

Jonathan Claussen applies carbon nanotube technology to a new propulsion system Collaborating with researchers at Brigham Young University and the U.S. Naval Research Laboratory, Jonathan Claussen is taking a well-known propulsion technique to the nanoscale. The team has developed a system that uses hydrogen peroxide decomposition to propel small underwater vehicles. “Hydrogen peroxide propulsion has [Continue Reading…]

Virtual reality puts football recruits in the middle of game day at Jack Trice Stadium

There you were, inside the C6 virtual reality room at Iowa State University, surrounded on six sides by 100 million pixels and completely immersed in the sights and sounds of game day at Jack Trice Stadium. The band marched in I-S-U formation. The cheerleaders did flips.

Iowa State engineer develops power-saving tools to keep solar-powered robots in action

The small robots in Ran Dai’s basement lab at Iowa State University look like fancy electronic toys. But they’re really very smart. And they’re getting smarter. Dai, an Iowa State assistant professor and Black and Veatch Faculty Fellow in aerospace engineering, is developing power-management technologies that would allow land- and air-based robots to monitor solar conditions so they can maximize operating efficiency and battery life.

Iowa State awarded NSF Global City Teams Challenge project

Part of $40 million White House Smart Cities Initiative A team of researchers from the Department of Electrical and Computer Engineering at Iowa State University was awarded one of 12 Global City Teams Challenge (GCTC) research projects by the National Science Foundation this week. The GCTC, a joint initiative of the National Institute of Standards [Continue Reading…]

NSF awards maximum support to Iowa State-based Center for Biorenewable Chemicals

The National Science Foundation (NSF) has added three years and $8.48 million to the grant supporting the NSF Engineering Research Center for Biorenewable Chemicals based at Iowa State University.

That brings NSF’s total funding of the center (known as CBiRC, “See-burk”) to the maximum allowed: 10 years and $35.26 million. NSF support of the center began in September 2008 and will end in August 2018. After that, the center must be self-supporting.

Iowa State, Argo Genesis Chemical to dedicate new, $5.3 million bio-polymer pilot plant

Eric Cochran led the way, counterclockwise, from one 500-gallon industrial tank to another and then another. By the time he got to the 1,300-gallon holding tank at the end he had explained how Iowa State University engineers are producing bio-polymers from soybean oil.
