Structural Studies of CaAl 12 O 19 , SrAl 12 O 19 , La 2/3+dAl d12-dO 19 , and CaAl 10 NiTiO 19 with the Hibonite Structure; Indications of an Unusual Type of Ferroelectric

Jun Li, Elena A. Medina, Judith K. Stalick, Arthur W. Sleight, M. A. Subramanian
Various oxides with the hibonite structure were synthesized and structurally analyzed using powder neutron diffraction. The structure of CaAl 12O 19 at 298 K and 11 K shows dipoles that are apparently too dilute to order unless subjected to a suitable

A Pathway to Optimize the Properties of Magnetocaloric Mn 2-x Fe x P 1-y Ge y ) for Magnetic Refrigeration

February 29, 2016

D. M. Liu, Z. L. Zhang, S. L. Zhou, Qingzhen Huang, X. J. Deng, M. Yue, C. X. Liu, J. X. Zhang, Jeffrey W. Lynn
Magnetocaloric materials can be useful in magnetic refrigeration applications, but to be practical the magnetorefrigerant needs to have a very large magnetocaloric effect (MCE) near room temperature for modest applied fields ( xFe 2-xP 1-yGe y, and we have

Real-time Photoluminescence Studies of Thin Film Formation in Organic Solar Cells

February 29, 2016
Author(s)
Sebastian Engmann, Felicia A. Bokel, Hyun W. Ro, Dean M. DeLongchamp, Lee J. Richter
We present a method to study the structural evolution of organic bulk-heterojunctions via real-time, in-situ, steady state photoluminescence (PL). In-situ PL, in combination with real-time transmission and reflection measurements, allowed us to

Variability and bias assessment in breast ADC measurement across multiple systems

February 29, 2016
Author(s)
Kathryn E. Keenan, Sheye O. Aliu, Lisa J. Wilmes, David C. Newitt, Ella F. Jones, Wen Li, Michael A. Boss, Karl F. Stupic, Stephen E. Russek, Nola M. Hylton
Purpose: To assess the ability of a recent, anatomically designed breast phantom incorporating T 1 and diffusion elements to serve as a quality control device for quantitative comparison of apparent diffusion coefficient (ADC) measurements calculated from

Linkage-Specific Conformational Ensembles of Non-Canonical Polyubiquitin Chains

February 28, 2016
Author(s)
Carlos A. Castaneda, Apurva Chaturvedi, Christina M. Camara, Joseph E. Curtis, Susan T. Krueger, David Fushman
Polyubiquitination is a critical protein post-translational modification involved in a variety of processes in eukaryotic cells. The molecular basis for selective recognition of the polyubiquitin signals by cellular receptors is determined by the

The CALPHAD method and its role in material and process development

February 26, 2016
Author(s)
Ursula R. Kattner
Successful design of materials and manufacturing processes requires the availability of reliable materials data. Commercial alloys usually contain a large number of elements, and the needed data for the design of new materials and processes are rarely

The Magnetic Transitions and Dynamics in the Multiferroic Lu 0.5 Sc 0.5 FeO 3

February 26, 2016
Author(s)
Junjie Yang, Chunruo Duan, John R. Copley, Craig Brown, Despina Louca
In spite of its frustrated lattice, the multiferroic Lu 0.5Sc 0.5FeO 3 exhibits two consecutive magnetic transitions at T% N1approximately equal to}175 K and T N2 approximately equal to}70 K determined from neutron diffraction. In the ordered state
