The Critical Materials Institute has created a new chemical process that makes use of the widely available rare-earth metal cerium to improve the manufacture of nylon. The process uses a cerium-based material made into nanometer-sized particles with a palladium catalyst to produce cyclohexanone, a key ingredient in the production of nylon.

Scientists at Ames Laboratory have developed a nanoparticle that is able to perform two processing functions at once for the production of green diesel, an alternative fuel created from the hydrogenation of oils from renewable feedstocks like algae. The method is a departure from the established process of producing biodiesel, which is accomplished by reacting fats and oils with alcohols.
Scientists at Ames Laboratory have observed magnetic properties typically associated with those observed in rare-earth elements in iron. These properties are observed in a new iron based compound that does not contain rare earth elements, when the iron atom is positioned between two nitrogen atoms.
Scientists at Ames Laboratory are revealing the mysteries of new materials using ultra-fast laser spectroscopy. Researchers recently used ultra-fast laser spectroscopy to examine and explain the mysterious electronic properties of iron-based superconductors. Seeing these dynamics is one emerging strategy to better understanding how these new materials work.
NASA on Wednesday confirmed a bonanza of 715 newly discovered planets outside our solar system. Scientists using the planet-hunting Kepler telescope pushed the number of planets discovered in the galaxy to about 1,700. Twenty years ago, astronomers had not found any planets circling stars other than the ones revolving around our sun.
Scientists at Ames Laboratory have discovered a new family of rare-earth quasicrystals using an algorithm they developed to help pinpoint them. Quasicrystalline materials may be found close to crystalline phases that contain similar atomic motifs, called crystalline approximants. And just like fishing experts know how to hook a big catch, the scientists used their knowledge to hone in on the right spot for their discovery.
Physicists at the U.S. Dept. of Energy's Ames Laboratory have discovered surprising changes in electrical resistivity in iron-based superconductors. The findings offer further evidence that magnetism and superconductivity are closely related in this class of novel superconductors.
The U.S. Department of Energy (DOE) has launched a research hub that focuses on solutions to the domestic shortages of rare earth metals and other materials critical for U.S. energy security.
Scientists at Ames Laboratory have discovered new ways of using a well-known polymer in organic light-emitting diodes (OLEDs), which could eliminate the need for an increasingly problematic and breakable metal-oxide used in screen displays. The polymer, known as PEDOT:PSS, has been around for about 15 years. However, until recently, the material wasn't sufficiently conductive or transparent enough to be a viable ITO substitute.
The prices for rare earths increased ten-fold between 2009 and 2011, prompting researchers at Ames Laboratory to revisit a rare earth recovery process once employed to make high-strength alloy. Now, they are working to more effectively remove neodymium, a rare earth element, from the mix of other materials in a rare earth magnet.
Glass materials may have a far less randomly arranged structure than formerly thought. Over the years, the ideas of how metallic glasses form have been evolving, from just a random packing, to very small ordered clusters, to realizing that longer range chemical and topological order exists. A team of scientists at the Ames Laboratory has been able to show for the first time there is some organization to these structures.
