Localization Model Description of Diffusion and Structural Relaxation in Superionic Crystalline UO2

August 15, 2019
Author(s)
Jack F. Douglas, Hao Zhang, Xinyi Wang
… between the α-structural relaxation time τα and oxygen ion diffusion coefficient DO with the Debye-Waller factor for … interactions lead to non-Arrhenius relaxation and high ion mobility. As in a previous study of structural relaxation … and the long-time structural relaxation time and oxygen ion diffusion coefficient holds to an excellent approximation …

Entanglement of Four Particles

January 1, 2000
Author(s)
C A. Sackett, D Kielpinski, B E. King, Christopher Langer, V Meyer, C J. Myatt, M A. Rowe, Q A. Turchette, Wayne M. Itano, David J. Wineland, C Monroe
Quantum mechanics allows for many-particle wavefunctions that cannot be factorized into a product of single-particle wavefunctions, even when the constituent particles are entirely distinct. Such ‘entangled’ states explicitly demonstrate the non-local

Characterization of Stabilized Zero Valent Iron Nanoparticles

December 10, 2011
Author(s)
Lauren F. Greenlee, Stephanie A. Hooker
The demonstrated toxicity of certain groups of organic micropollutants in water sources has motivated research in developing novel materials that are able to remove dissolved organic molecules from an aqueous system through adsorption and/or degradation

Ralaxometry and Magnetometry of Ferritin

December 1, 1998
Author(s)
R A. Brooks, J Vymazal, Ronald B. Goldfarb, J W. Bulte, P Aisen
By combining nuclear magnetic ralaxometry on 39 ferritin samples with different iron loading with magnetometry, results were obtained that suggest a new interpretation of the core structure and magnetic properties of ferritin. These studies provide
