Chemists use abundant, low-cost and non-toxic elements to create semiconductors

Semiconductors are everywhere. They’re on our computers and our cell phones. They’re usually in high-end, high-value products. While semiconductors may not contain rare materials,...

‘eFeed-Hungers’ software aims to reduce food waste

A group of researchers designed the software so that donors can take the food to a public place, such as a food pantry or...
Iowa State engineers -- left to right, Boyce Chang, Martin Thuo, Michael Bartlett and Ravi Tutika -- helped develop and describe a new smart material. Here they examine an instrument used for mechanical testing of material properties. Larger photo

New composite material that changes stiffness when twisted or bent

The Iowa State engineers invented a novel responsive and smart material that can stiffen up like a worked-out muscle. This material has to arrest...
