411. Sample-Angle Feedback for Diffraction Anomalous Fine-Structure Spectroscopy
Topic: Materials Science
Published: 5/1/1998
Authors: J O Cross, W Elam, V G Harris, J P Kirkland, Charles E. Bouldin, L B Sorensen
Abstract: Diffraction anomalous fine-structure (DAFS) experiments measure Bragg peak intensities as continuous functions of photon energy near a core-level excitation. Measuring the integrated intensity at each energy makes the experiments prohibitively slow, ...

412. X-Ray Diffraction Topography of Sapphire for Windows and Domes
Topic: Materials Science
Published: 3/30/1998
Author: David R Black
Abstract: X-ray diffraction topography has been used as a nondestructive characterization tool to investigate single-crystal sapphire for window and dome applications. A variety of examples are shown that demonstrate the utility of x-ray diffraction imaging a ...

414. The Economics of New-Technology Materials: A Case Study of FRP Bridge Decking
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5864
Topic: Materials Science
Published: 7/1/1996
Authors: M A Ehlen, Harold E. Marshall
Abstract: Many new materials are bing developed from polymers, metals, and ceramics. Industry is beginning to introduce some of these high-performance or new-technology materials in construction and manufacturing applications because the materials have advant ...

Series: Handbook (NIST HB)
Report Number: 135
Topic: Materials Science
Published: 2/1/1996
Authors: S Fuller, Steve Petersen
Abstract: Handbook 135 is a guide to understanding the life-cycle cost (LCC) methodology and criteria established by the Federal Energy Management Program (FEMP) for the economic evaluation of energy and water conservation projects and renewable energy project ...

416. Thermomechanical Detwinning of Superconducting YBa2Cu3O7-x Single Crystals
Topic: Materials Science
Published: 7/11/1989
Authors: Debra L Kaiser, Frank W Gayle, Robert S. Roth, L Swartzendruber
Abstract: A method for the complete removal of twins from single crystals of superconducting YBa2Cu3O7-x is described. The process depends on ferroelastic behavior found to exist in the phase, and should be generally applicable to the layered perovskite-type p ...

417. A nonlinear model for gusset plate connections
Topic: Materials Science
Published: Date unknown
Authors: Dat Duthinh, Chiara Crosti
Abstract: The investigation of the 2007 collapse of the I-35 W Bridge in Minnesota, United States, used very detailed nonlinear finite-element (FE) analysis, which is too difficult for routine design. On the other hand, simple guidelines amenable to hand calcu ...

418. Ab initio study of the mechanical and the transport properties of pure and contaminated silver nanowires
Topic: Materials Science
Published: Date unknown
Authors: Shmuel Barzilai, Francesca M Tavazza, Lyle E Levine
Abstract: The conductance and mechanical properties of pure and contaminated silver nanowires were studied using density functional theory (DFT) calculations. Several nanowires containing O2 on their surface were elongated along two different directions. All o ...

419. Characterization of Standard Reference Material 2942, Ce-Ion-Doped Glass, Spectral Correction Standard for UV Fluorescence
Topic: Materials Science
Published: Date unknown
Authors: Paul C DeRose, Melody V Smith, Klaus Mielenz, Jeffrey R Anderson, Gary W Kramer
Abstract: Standard Reference Material (SRM) 2942 is a cuvette-shaped, Ce-ion-doped glass, recommended for use for relative spectral correction of emission and day-to-day performance verification of steady-state fluorescence spectrometers. Properties of this st ...

420. Characterizing and Fractionating Native Cellulose Nanofibers
Topic: Materials Science
Published: Date unknown
Authors: Iulia Alisa Sacui, Jeffrey W Gilman
Abstract: Cellulose nanofibers have good elastic modulus properties and can be used as nano-reinforcements in polymer composites. Native cellulose nanofibers from wood, Tunicate, and bacteria (Acetobacter xylium) were characterized by atomic force microscopy ( ...
