Neutron scattering characterizes dynamics in polymer family
December 01, 2012 — Understanding the interplay between structure and dynamics is the key to obtaining tailor-made materials. In the last few years, a large effort has been devoted to characterizing and relating the structure and dynamic properties in families of polymers with alkyl side groups.
Theory meets experiment: structure-property relationships in an electrode material for solid-oxide fuel cells
December 01, 2012 — Fuel cell technology is one potentially very efficient and environmentally friendly way to convert the chemical energy of fuels into electricity. Solid-oxide fuel cells (SOFCs) can convert a wide variety of fuels with simpler, cheaper designs than those used in liquid electrolyte cells.
Neutron diffraction reveals promising new phosphor for white lighting in LEDs
November 01, 2012 — That college student working bleary eyed at her laptop at 3 am, that football fan capturing a brilliant touchdown with his cellphone—both are relying on new white lighting technology based on light emitting diodes (LEDs).
Neutron experiments give unprecedented look at quantum oscillations
October 23, 2012 — 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.
POWGEN workshop nets PhD student a paper in Journal of Solid State Chemistry
May 01, 2012 — A young Oregon State University graduate student has successfully turned her participation in a two-day POWGEN Neutron Diffraction workshop at the Spallation Neutron Source (SNS) into a published paper in the Journal of Solid State Chemistry.
SNS Diffractometer puts the squeeze on methane hydrate cages, unraveling its high-pressure structure
March 01, 2012 — Imagine a robot sent out on the prowl on this energy hungry planet looking for methane, the principal component of what we call “natural gas” and probably the most abundant organic compound on earth.
Neutrons Probe Inner Workings of Batteries
February 01, 2012 — Listen for any length of time to Ke An, lead scientist for the VULCAN Engineering Materials Diffractometer at the Spallation Neutron Source, and you're sure to hear about the capabilities of VULCAN that aren't available anywhere else.
