We have fabricated all-thin-film solid oxide fuel cell (SOFC) heterostructures and investigated the transport properties of Sm0.2Ce0.8O2-δ (SDC20) in an out-of-plane measurement geometry. The SOFC heterostructures, consisting of a bottom SrRuO3 (SRO) or

Amorphous Alloys Containing Cobalt for Orthopaedic Applications

November 1, 1998
Author(s)
John A. Tesk, C E. Johnson, Drago Skrtic, Ming S. Tung, Stephen M. Hsu
Amorphous metal alloys have properties and structures unlike those of theircrystalline counterparts. For example, a multiphase crystalline structure may exhibit poor corrosion resistance while the amorphous structure is corrosion resistant. The high

… autonomously offroad at speeds up to 35 km/h (10 m/s, 20 mph). Key features of the implementation that enable driving at these speeds are (1) planning the next 20 m with dynamically feasible trajectories, and (2) …

Latent Fingerprint Performance Modeling

January 14, 2008
Author(s)
Vladimir N. Dvornychenko
This paper describes aspects of work done at NIST, in concert with the latent fingerprint community, toward achieving a partial lights-out latent fingerprint processing capability. The initial steps are to quantify performance over a cross-section of

Temperature Measurements of Semiconductor Devices-A Review

March 10, 2004
Author(s)
David L. Blackburn
There are numerous methods for measuring the temperature of an operating semiconductor device. The methods can be broadly placed into three generic categories; electrical, optical, and physically contacting. The fundamentals underlying each of the

Polymer Dynamics and Diffusive Properties in Ultra-Thin Photoresist Films

Author(s)
Christopher L. Soles, Ronald L. Jones, Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, Vivek M. Prabhu, Wen-Li Wu, Eric K. Lin, D L. Goldfarb, M Angelopoulos
A series of experiments are presented to demonstrate thin film confinement effects on the diffusive properties in poly(tert-butoxycarboxystyrene) (PBOCSt). Bilayer diffusion couple measurements reveal that as the thickness of a PBOCSt film is decreased

Tolerancing Form Deviations for Rockwell Diamond Indenters

September 1, 2002
Author(s)
Jun-Feng Song, Samuel R. Low III, Li Ma
The spherical tip of Rockwell diamond indenters tends to be manufactured either a flat- or sharp-shaped surface because of the anisotropy property of the diamond. This can cause significant differences in the hardness readings. In order to control that
