Researchers at the U.S. Department of Energy’s Ames Laboratory have designed and built an advanced model system that successfully uses very small quantities of magnetocaloric materials to achieve refrigeration level cooling. The development marks an important step in creating new technologies to replace 100-year-old gas compression refrigeration with solid-state systems up to 30 percent more energy efficient.

Paul Dabbar, the Department of Energy Under Secretary for Science, visited Ames Laboratory on Tuesday, March 27 for facilities tours and discussions with laboratory leadership and scientists. The tours and meetings highlighted the breadth and depth of Ames Laboratory’s specialization in materials science and engineering, including high-purity metals preparation, advanced powder synthesis, condensed matter physics, quantum materials, exascale computational development, catalysis, and chemical sciences research.
A new biochemical leaching process has been developed that uses corn stover as feedstock, and recovers valuable rare earth metals from electronic waste.
It’s nothing new to Iowans that corn and its byproducts can be used for high-tech applications ranging from bioplastics to ethanol. Using corn stover for what is essentially a mining process may seem like a stretch even for Iowa – the world’s biggest producer of corn—but the new process does indeed use stover as a key ingredient. The research was directed by the U.S. Department of Energy’s Critical Materials Institute (CMI)
Middle school students from across Iowa will gather in Ames on Feb. 24 to compete in the 2018 Ames Laboratory/Iowa State University Regional Middle School Science Bowl. Twenty-four teams of students will compete to answer questions about biology, chemistry, earth and space science, energy, mathematics, and physics in the day-long, quiz-bowl format competition.
MEDIA ADVISORY -- Feb. 16, 2018
The Department of Energy’s (DOE’s) National Laboratories are among the most innovative places on the planet.
Forged in the fires of World War II, they have become wellsprings of discovery and innovation that have made – and continue to make – a profound and positive impact on the lives of millions. Partnering with industry and academia, the National Laboratories continue to drive fundamental research, innovation and commercialization, advancing U.S. leadership and unleashing American energy, ingenuity and genius.
