Change Agent: James Hill, Team PrISUm mentor

This story was originally published by University News Service AMES, Iowa – Wade Johanns had the honor of announcing the second-ever Lifetime Achievement Award from the organizers of the American Solar Challenge, a cross-country race for student-designed and student-built solar cars. Johanns has two engineering degrees from Iowa State University and spent years as a [Continue Reading…]

Iowa State scientists develop quick-destructing battery to power ‘transient’ devices

AMES, Iowa – Self-destructing electronic devices could keep military secrets out of enemy hands. Or they could save patients the pain of removing a medical device. Or, they could allow environmental sensors to wash away in the rain. Making such devices possible is the goal of a relatively new field of study called “transient electronics.” [Continue Reading…]

Iowa school teams, individuals head to science and technology world championship

This story was originally posted with the Iowa State News Service.  When it launches basketball-sized “boulders” at a castle tower, the robot built by a team of students from Cedar Falls High School can’t see over defending robots. So, at 8:30 on a recent school night, team members were at school, working to solve the [Continue Reading…]

Iowa State engineers develop micro-sized, liquid-metal particles for heat-free soldering

Martin Thuo likes to look for new, affordable and clean ways to put science and technology to work in the world. His lab is dedicated to an idea called frugal innovation: “How do you do very high-level science or engineering with very little?” said Thuo, an assistant professor of materials science and engineering at Iowa State University and an associate of the U.S. Department of Energy’s Ames Laboratory.

Change Agent: Bong Wie

Bong Wie sent his hands flying, simulating an explosion right there in his Howe Hall office. If his ideas become reality and spacecraft carrying nuclear explosives fly into asteroids one day, “The asteroid can be pulverized – not just fragmented – into dust!” he said, his hands going wild.

Iowa State’s ATHENA Lab dedicated to augmenting, understanding human performance

The first thing you noticed during a visit to a new Iowa State University engineering laboratory was the full-sized mannequin lying across a table. That’s for studies to improve suturing techniques and tools. Then there was a bin full of basketball shoes. Those are for studies of tread patterns and their effects on traction and performance.

Iowa State engineers develop flexible skin that traps radar waves, cloaks objects

Iowa State University engineers have developed a new flexible, stretchable and tunable “meta-skin” that uses rows of small, liquid-metal devices to cloak an object from the sharp eyes of radar. The meta-skin takes its name from metamaterials, which are composites that have properties not found in nature and that can manipulate electromagnetic waves.

Iowa State engineers develop hybrid technology to create biorenewable nylon

Engineers at Iowa State University have found a way to combine a genetically engineered strain of yeast and an electrocatalyst to efficiently convert sugar into a new type of nylon. Previous attempts to combine biocatalysis and chemical catalysis to produce biorenewable chemicals have resulted in low conversion rates.

Iowa State challenges students to turn back cyber attacks, keep lights on, water running

Teams of students will face eight straight hours of attacks on the computers and networks behind a simulated city’s power and water utilities. Can they protect all the software, hardware and connections? Will the lights stay on? Will the water run? Will the residents of a small, fictional city be without critical services and infrastructure?

Presidential research initiative builds, advances four big data research teams

The second round of awards from Iowa State University’s Presidential Initiative for Interdisciplinary Research will help build four big data research teams and launch major projects in digital agriculture and intelligent text analysis.

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.
