Middle School Science Bowl Feb. 16

Middle school students from across Iowa will gather in Ames on Feb. 16 to compete in the 2019 Ames Laboratory/Iowa State University Regional Middle School Science Bowl. Thirty-two 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.

Catching atoms in action: watching next-gen materials crystallize

Experts in capturing atomic-level details of complex materials transformations, Ames Laboratory scientists melted, super-cooled and then reheated a model alloy of aluminum and samarium, and monitored the reheating process in real time with a combination of high-energy x-ray diffraction and transmission electron microscopy.

Taking magnetism for a spin: exploring the mysteries of skyrmions

Scientists at the U.S. Department of Energy’s Ames Laboratory have discovered the relaxation dynamics of a zero-field state in skyrmions, a spinning magnetic phenomenon that has potential applications in data storage and spintronic devices.

Ames Laboratory hosting 29th annual High School Science Bowl

Iowa's top science and math students will face-off here on Jan. 26 in an intense question and answer competition in the 29th annual Ames Laboratory/Iowa State University Regional High School Science Bowl. Forty teams of students will compete to answer questions that test their knowledge of biology, chemistry, Earth and space science, energy, mathematics, and physics in the day-long, quiz-bowl format competition.

What should we do about single-use plastics? Tackling the growing problem of trash we can’t recycle

Researchers are looking at ways to upcycle plastics -- breaking down long polymer chains into shorter segments that can then be reused for a variety of chemicals and materials.

Physicists uncover new competing state of matter in superconducting material

A team of experimentalists at the U.S. Department of Energy’s Ames Laboratory and theoreticians at University of Alabama Birmingham discovered a remarkably long-lived new state of matter in an iron pnictide superconductor, which reveals a laser-induced formation of collective behaviors that compete with superconductivity.

Depiction of laser pulse excitement of electrons in superconducting material

CMI one of 32 R&D 100 Award winners for Department of Energy

Researchers at the Critical Materials Institute (CMI) and Ames Laboratory are winners of an R&D 100 Award. Researchers invented a magnet recycling process in which magnets are dissolved in water-based solutions, recovering more than 99 percent purity rare earth elements.

Critical Materials Institute takes major step toward printed anisotropic magnets

The U.S. Department of Energy’s Critical Materials Institute has taken a major step toward printed, aligned anisotropic magnets via additive manufacturing processes. The Energy Innovation Hub manufactured hybrid nylon bonded neodymium-iron-boron and samarium-iron-nitrogen magnet using the Big Area Additive Manufacturing (BAAM) located at Oak Ridge National Laboratory.

Finding better magnets faster with 3D metal printing prototyping

The U.S. Department of Energy’s Critical Materials Institute (CMI) used laser 3D metal printing to optimize a permanent magnet material that may make an economical alternative to the more expensive rare-earth neodymium iron boron (NdFeB) magnets in some applications.

CaloriSMART test system succeeds in magnetocaloric cooling

Researchers at 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.
