11. EXAFS Studies of Catalytic DNA Sensors for Mercury Contamination of Water
Topic: Ceramics
Published: 12/11/2009
Authors: Bruce D Ravel, S.C. Slimmer, X. Meng, G.C.L. Wong, Y. Lu
Abstract: Monitoring of metallic contaminants in domestic and agricultural water systems systems requires technology that is fast, flexible, sensitive, and selective. Recently, metal sensors based on catalytic DNA have been demonstrated as a practical monitor ...

12. Enhanced Water Splitting Performance of Potassium-Adsorbed Titania Nanotube Arrays
Topic: Ceramics
Published: 12/7/2009
Authors: Christiaan Richter, Cherno Jaye, Eugen Panaitescu, Daniel A Fischer, Laura H. Lewis, Ronald J. Willey, Latika Menon
Abstract: It is demonstrated that vertically-aligned titania nanotube planar arrays fabricated by electrochemical anodization using standard potassium-containing electrolytes invariably contain a significant amount of surface-adsorbed potassium ions that enhan ...

13. Characterization of Fly Ash Reactivity in Hydrating Cement by Neutron Scattering
Topic: Ceramics
Published: 7/14/2009
Authors: W Bumrongjaroen, Richard A Livingston, Dan A. Neumann, Andrew John Allen
Abstract: A combination of small-angle and inelastic neutron scattering studies are presented to elucidate the different effects of Class F and Class C fly ash additions on microstructure development in hydrating cement (and concrete). Small angle neutron sca ...

14. Effect of a Compressive Uniaxial Strain on the Critical Current Density of Grain Boundary in Superconducting YBa^d2^Cu^d^3O^d7-{delta}^ Films
Topic: Ceramics
Published: 7/10/2009
Authors: Daniel Cornelis van der Laan, Timothy J. Haugan, Paul N. Barnes
Abstract: Grain boundaries can be a significant barrier for current flow in high temperature superconducting (HTS) thin films. We show that an applied compressive strain causes a remarkable increase in critical current density (Jc,GB) in thin film YBa^d2^Cu^d3 ...

15. Annealing Behavior of Atomic Layer Deposited HfO2 Films Studied by Synchrotron X-Ray Reflectivity and Grazing Incidence Small Angle Scattering
Topic: Ceramics
Published: 6/30/2009
Authors: Martin L Green, Andrew John Allen, J. L. Jordan-Sweet, Jan Ilavsky
Abstract: New results are presented for the annealing behavior of ultrathin complementary-metal-gate-semiconductor (CMOS) gate-dielectric (high-) HfO2 films grown by atomic layer deposition (ALD). A series of ALD HfO2 dielectric films has been stu ...

16. Thermoelectric and Structural Characterization of Ba2Ho(Cu3-xCox)O6+y
Topic: Ceramics
Published: 6/13/2009
Authors: Winnie K Wong-Ng, Z Yang, Y F Hu, Qingzhen Huang, Nathan Lowhorn, Makoto Otani, James A Kaduk, Martin L Green, Q Li
Abstract: The search for thermoelectric materials for power generation and for solid-state cooling have led to the increased interest of layered cobalt-containing oxides because of their thermal stability at high temperature and their desirable thermoelectric ...

17. Multi-Scale Microstructure Characterization of Solid Oxide Fuel Cell Assemblies with Ultra Small-Angle X-Ray Scattering
Topic: Ceramics
Published: 6/11/2009
Authors: Andrew John Allen, Jan Ilavsky, Artur Braun
Abstract: The structure of three solid oxide fuel cell assemblies with 200 micrometers nominal thick-ness in the transverse plane, before and after operation, and with and without sulfur con-taining fuel, is quantified with ultra small angle x-ray scattering ( ...

18. A High-throughput Screening System for Thermoelectric Material Exploration Based on Combinatorial Film Approach
Topic: Ceramics
Published: 5/7/2009
Authors: Makoto Otani, Evan L. Thomas, Winnie K Wong-Ng, Peter K. Schenck, Nathan Lowhorn, Martin L Green, Hiroyuki Ohguchi
Abstract: A high-throughput system that consists of a combinatorial tool (a sputtering deposition tool and a pulsed laser deposition tool) and two property screening devices, developed at NIST, was used for thermoelectric material exploration. The thermoelectr ...
