Researchers See Rare-earth-like Magnetic Properties In Iron
2014-04-30 14:11:06

Ames Laboratory Scientists at the Department of Energy’s 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. The discovery opens the possibility of using iron to provide both the magnetism and permanence in high-strength permanent magnets, like those used in...

Light Triggers Ripples In Crystals

University of California - San Diego First propagating surface phonon polaritons in a van der Waals crystal Light can trigger coordinated, wavelike motions of atoms in atom-thin layers of crystal, scientists have shown. The waves, called phonon polaritons, are far shorter than light waves and can be "tuned" to particular frequencies and amplitudes by varying the number of layers of crystal, they report in the early online edition of Science March 7. These properties - observed in...

Researchers Invent ‘Sideways’ Approach To 2-D Hybrid Materials
2014-01-10 14:06:22

Oak Ridge National Laboratory Researchers at the Department of Energy’s Oak Ridge National Laboratory and the University of Tennessee, Knoxville have pioneered a new technique for forming a two-dimensional, single-atom sheet of two different materials with a seamless boundary. The study, published in the journal Science, could enable the use of new types of 2-D hybrid materials in technological applications and fundamental research. By rethinking a traditional method of growing...

Novel plasmonic material may merge photonic and electronic technologies Helping bridge the gap between photonics and electronics, researchers from Purdue University have coaxed a thin film of titanium nitride into transporting plasmons, tiny electron excitations coupled to light that can direct and manipulate optical signals on the nanoscale. Titanium nitride's addition to the short list of surface-plasmon-supporting materials, formerly comprised only of metals, could point the way to a...

Just 100 nanometers in diameter, nanowires are often considered one-dimensional. But researchers at Northwestern University have recently reported that individual gallium nitride nanowires show strong piezoelectricity — a type of charge-generation caused by mechanical stress — in three dimensions. The findings, led by Horacio Espinosa, James N. and Nancy J. Farley Professor in Manufacturing and Entrepreneurship at the McCormick School of Engineering and Applied Science, were...

Hexagonal boron nitride sheets may help graphene supplant silicon What researchers might call "white graphene" may be the perfect sidekick for the real thing as a new era unfolds in nanoscale electronics. But single-atom-thick layers of hexagonal boron nitride (h-BN), the material under intense study at Rice University's world-class Department of Mechanical Engineering and Materials Science, are likely to find some macro applications as well. Researchers in the lab of Pulickel Ajayan, Rice's...
