131. Assessment of the Completeness of Engineering Ceramic Materials in the ICDD;s PDF
Published: Date unknown
Authors: C R Hubbard, Winnie K Wong-Ng, J Rodgers
Abstract: For over forty years the International Center for Diffraction Data (ICDD) has maintained an effort to prepare high quality x-ray reference powder diffraction patterns and data for the Powder Diffraction File (PDF). Part of the ongoing effort of the ...

132. Control of Nanophase Defects During Ceramic Melt Processing of Bi2Sr2CaCu2O8+x High Tc Superconductors
Published: Date unknown
Authors: T J Haugan, Winnie K Wong-Ng, Lawrence P. Cook, H J Brown, L Swartzendruber
Abstract: To improve the critical current density of Bi^d2^Sr^d2^CaCu^d2^O^d8+x^ high temperature superconductors (HTS) in high magnetic field applications (> 1 T from 20 K to 50 K), it is necessary to introduce a high density ({approximately equal to} 5 per 1 ...

133. Crystallography and Crystal Chemistry of (Ba^d1-x^Sr^dx^)2TiO^d4^
Published: Date unknown
Authors: Winnie K Wong-Ng, James A Kaduk, Debra L Kaiser, Julia Frank
Abstract: This paper reports an investigation of the homogeneity range, crystal chemistry and crystallography of a technologically-important (Ba2-xSrx)TiO4 solid solution series. Since the end members of the series - Ba2TiO4 (Pnma (No.62)) and Sr2TiO4 (I4/mmm ...

134. Flux-Pinning of Bi^d2^Sr^d2^CaCu^d2^O^d8^ High T^dc^ Superconducting Tapes Utilizing (Sr,Ca)^d14^Cu^d24^O^d41^ and Sr^d2^CaAl^d2^O^d6^ Defects
Published: Date unknown
Authors: T J Haugan, Winnie K Wong-Ng, Lawrence P. Cook, L Swartzendruber, H J Brown, D T Shaw
Abstract: Efforts to improve the magnetic flux-pinning properties of Bi^d2^Sr^d2^Ca^d1^Cu^d2^0^d8 +{delta} /Ag (2212/Ag) tape conductors utilizing (Sr^d1-x^Ca^dx^)14Cu^d24^0^d41+{delta} (014x24) and Sr^d2^CaA1^d2^0^d6^ (03A1^d2^) defects are described. Precu ...

135. High-Temperature X-Ray Diffraction Study of Phase Evolution in Ba^d2^YCu^d3^O^d6+x^ Films Using the BaF^d2^ Conversion Process
Published: Date unknown
Authors: Winnie K Wong-Ng, Igor Levin, Mark D Vaudin, Ron Feenstra, Lawrence P. Cook, James P Cline
Abstract: In-situ high-temperature x-ray diffraction (HTXRD) was used to study the phase formation and reaction kinetics of the Ba^d2^Ycu^d3^O^d6+x^ (Y-213) phase using the ex-situ BaF^d2^ conversion process. Three sets of films on single crystal SrTiO^d3^ su ...

136. Low Temperature Electronics and Low-Temperature Cofired Ceramics Based Electronic Devices
Published: Date unknown
Authors: C L Claeys, Winnie K Wong-Ng, K M Nair

137. Melting Equilibria of the BaF^d2^-CuO^dx^ System
Published: Date unknown
Authors: Winnie K Wong-Ng, Lawrence P. Cook, J Suh
Abstract: Since the BaF^d2^-CuO^dx^ system is a limiting binary of the overall quaternary reciprocal Ba,Y,Cu//F,O phase diagram, it provides an important frame of reference for studying the more complicated multi-component system. The phase diagrams of the Ba ...

138. Nano/Bioscience and Technology Education for the 21st Century
Series: Special Publication (NIST SP)
Report Number: 1063
Published: Date unknown
Authors: J Jacobs, Winnie K Wong-Ng, Gale Antrus Holmes, Richard F Kayser
Abstract: NEW:Update 2005, the 20th annual workshops for science and technology educators with the theme, NANO/BIOSCIENCE AND TECHNOLOGY EDUCATION FOR THE 21ST CENTURY, was hosted by the National Institute of Standards and Technology/Materials Science and Eng ...

139. Phase Equilibria of the High Tc Superconductors in the (Bi, Pb) -SR-Ca-Cu-O System
Published: Date unknown
Authors: Winnie K Wong-Ng, Lawrence P. Cook, W Greenwood, Anthony J Kearsley
Abstract: Applications of (Bi,Pb)-Sr-Ca-Cu-O phase equilibria include material synthesis, melt processing and single crystal growth. Both liquidus and subsolidus data are of central importance. For the determination of liquidus data, we have used a wicking t ...

140. Phase Relations in Ba-(Nd,Eu,Gd)-Cu-O Coated Conductor Films
Published: Date unknown
Authors: Winnie K Wong-Ng, Igor Levin, Joseph J. Ritter, Lawrence P. Cook, Guangyao Liu, Makoto Otani, Christopher E Lucas, Shailee P Diwanji, Ron Feenstra, P Goyal, Mark D Vaudin
Abstract: Knowledge of phase relations in thin films of Ba2RCu3O6+x (where R=lanthanides or mixed lanthanides) is needed to guide the processing of coated conductors. High-temperature X-ray diffraction studies of Ba2RCu3O6+x films deposited using the trifluor ...
