New Gel Promotes Bone Growth On Implants Used In Surgical Procedures
2014-03-31 14:11:46

Uppsala University A research group at Uppsala University, Sweden has developed a new responsive coating for implants used in surgery to improve their integration into bone and to prevent rejection. Neutron scattering experiments at the Institut Laue-Langevin (ILL) in Grenoble, France have shown how a protein that promotes bone growth binds to this surface and can be released in a controlled way. Orthopedic and dental implants must last for many years. Success for these surgical...

Unprecedented Look At Quantum Oscillations Through Neutron Experiments
2012-10-23 13:30:32

Researchers at the Department of Energy's Oak Ridge National Laboratory have found that nitrogen atoms in the compound uranium nitride exhibit unexpected, distinct vibrations that form a nearly ideal realization of a physics textbook model known as the isotropic quantum harmonic oscillator. In the experiment on the uranium nitride crystal -- with each of the light nitrogen atoms centered in a cage of heavier uranium atoms -- neutron scattering at ORNL's Spallation Neutron Source (SNS)...

Neutron analysis of the atomic dynamics behind thermal conductivity is helping scientists at the Department of Energy's Oak Ridge National Laboratory gain a deeper understanding of how thermoelectric materials work. The analysis could spur the development of a broader range of products with the capability to transform heat to electricity. Researchers performed experiments at both of ORNL's neutron facilities -- the Spallation Neutron Source and the High Flux Isotope Reactor -- to learn why...

The Cold Triple Axis spectrometer, a new addition to Oak Ridge National Laboratory's High Flux Isotope Reactor and a complementary tool to other neutron scattering instruments at ORNL, has entered its commissioning phase. The CTAX uses "cold" neutrons from the HFIR cold source to study low-energy magnetic excitations in materials. Cold neutrons are slower than their "thermal" neutron counterparts, and thus perfect for probing low-energy dynamics. The instrument, which moves by way of air pads...

Findings released at the annual Goldschmidt Conference at the University of Tennessee, Knoxville New intense sources of radiation at national facilities in Chicago, New York, and Tennessee coupled with the next generation of sensitive detectors are allowing geochemists like John Parise to gather images and data on minerals in one second that would take years of equivalent exposure on conventional laboratory x-ray facilities. John Parise, professor, mineralogist and solid-state chemist at...

CHARLOTTE, N.C., May 5 /PRNewswire/ -- Hendrick Construction, Inc. finished a 14,000-square-foot expansion project at Oak Ridge National Laboratory, upgrading lab space at one of the world's premier research facilities. The Tennessee project created 13 new labs to support scientific research conducted at the Spallation Neutron Source (SNS), the world's most powerful pulsed source of neutrons for the study of materials. Scientific understanding of the molecular structure of materials is...

Neutron scattering experiments performed at the Department of Energy's Oak Ridge National Laboratory give strong evidence that, if superconductivity is related to a material's magnetic properties, the same mechanisms are behind both copper-based high-temperature superconductors and the newly discovered iron-based superconductors. The work, published in a recent Nature Physics, was performed at ORNL's Spallation Neutron Source (SNS) and High Flux Isotope Reactor (HFIR) along with the ISIS...

The Department of Energy's Spallation Neutron Source (SNS), already the world's most powerful facility for pulsed neutron scattering science, is now the first pulsed spallation neutron source to break the one-megawatt barrier. "Advances in the materials sciences are fundamental to the development of clean and sustainable energy technologies. In reaching this milestone of operating power, the Spallation Neutron Source is providing scientists with an unmatched resource for unlocking the secrets...

Word of the Day
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
