Iowa State engineer part of defense department study of spray behavior, control

Engineers from across the country — including Iowa State’s Ted Heindel — will study the prediction and control of sprays as part of a U.S. Department of Defense research initiative. The engineers say a better understanding of spray physics and control could improve combustion systems, liquid cooling, 3D printing and even help mitigate ship wakes. The Defense Department is supporting the research team with a grant of up to $7.5 million over five years.

Cyclone Space Mining doubles down on new and better robot technology

Mr. Rare Earth, Karl Gschneidner passes away on April 27

The internationally-recognized Iowa State alum, professor and researcher Karl A. Gschneidner Jr. passed away on the morning of April 27 at the age of 85. Gschneidner’s work with rare-earth materials led to the creation of the Critical Materials Institute at Ames Laboratory as well as the publishing of over 544 of his scientific journal articles and [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.

Dean Rajala receives national engineer of the year award

Sarah Rajala, dean of the Iowa State University College of Engineering, has been named national engineer of the year by the American Association of Engineering Societies (AAES) – representing 17 multidisciplinary engineering societies from industry, government and academia. Rajala received the award on April 18 at a ceremony in Washington D.C. The AAES national engineer [Continue Reading…]

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 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.
