971. Effects of Large Grains on Transgranular Fracture Toughness
Topic: Ceramics
Published: Date unknown
Author: Stephen Weil Freiman
Abstract: This paper addresses issues of fracture for materials in which large grains, exist in a matrix of much smaller grains. Materials used for optical components, such as ZnS and ZnSe frequently fall into this category. For materials of this sort failur ...

972. Effects of Long Wavelength UV Irradiation on PFPE Molecular Bonding on CN^dx^ for Magnetic Recording Hard Disks
Topic: Ceramics
Published: Date unknown
Authors: J Zhang, Stephen M. Hsu, T Y Liew
Abstract: The use of long wavelength UV irradiation (320 to 390 nm) to induce bonding of a perffluoropolyether (PFPEP on CNx disks has been successfully demonstrated. Disks with 100 % mobile molecules, 100% bonded molecules, and a 50:50 mixture of mobile and ...

973. Effects of Polarity on Grain Boundary Migration in ZnO
Topic: Ceramics
Published: Date unknown
Authors: Jong Sook Lee, Sheldon Martin Wiederhorn
Abstract: Boundary migration of ZnO has been investigated using single crystals with defined crystallographic orientations. The migration rate of the basal C planes depended on the crystallographic polarity: Zn-terminated positive (0001)-planes. The migratio ...

974. Effects of Solution pH and Surface Chemistry on the Post-Deposition Growth of Chemical Bath Deposited PbSe Nanocrystalline Films
Topic: Ceramics
Published: Date unknown
Authors: Shaibai K Sarkar, Shifi Kababya, Shimon Vega, Hagal Cohen, Joseph C Woicik, A I Frenkel, Gary Hodes
Abstract: Chemical bath deposited PbSe films were subjected to post-deposition treatment with aqueous (typically 0.25 - 0.5 M) KOH. For films deposited using a citrate complex, this treatment resulted in dissolution of surface lead oxides (seen from XPS and EX ...

976. Elastic Modulus Measurements in Plasma Sprayed Deposits
Topic: Ceramics
Published: Date unknown
Authors: Jay S Wallace, J Ilavsky
Abstract: A technique has been developed to characterize the elastic modulus of zirconium oxide-8% yttrium oxide plasma sprayed deposits. A commercial hardness indenter has been modified to record load-displacement as a spherical ball is elastically loaded on ...

977. Electron Backscatter Diffraction Investigation of a Nano-Crystalline Pt Thin Film
Topic: Ceramics
Published: Date unknown
Authors: T Maitland, X Han, Mark D Vaudin, G R Fox, M Coy
Abstract: A polycrystalline Pt thin film deposited on a <100> cut Si single crystal wafer coated with SiO2 and a TiO2 adhesion layer was studied using automated electron backscatter diffraction (EBSD). Integration of the EBSD detector and a scanning electron ...

978. Elucidating Thermo-Mechanical Spallation of Thermal Barrier Coating-Systems Using Controlled Indentation Flaws
Topic: Ceramics
Published: Date unknown
Authors: M Bartsch, B Baufeld, Lin-Sien H Lum
Abstract: ramic thermal barrier coatings (TBC) can exhibit premature in-service failure due to spallation as a consequence of exposure to elevated temperatures, aggressive environments, and cyclic loading. Lifetime assessment for TBC-systems requires methods ...

979. Engineering of Self-Assembled Domain Architectures With Ultra-High Piezoelectric Response in Epitaxial Ferroelectric Films
Topic: Ceramics
Published: Date unknown
Authors: J.H. Yang, Julia Slutsker, Igor Levin, D H Kim, Chang-Beom Eom, R Ramesh, Alexander Lazar Roytburd
Abstract: Non-180 domain wall movement, which makes a large contribution to the piezoelectric response of ferroelectric bulk materials, were found to be much more difficult in epitaxial films, because of substrate clamping and inter-domain pinning. Through th ...

980. Enhancement of Mercuric Iodide Detector Performance Through Crystal Growth in Microgravity: The Roles of Lattice Order
Topic: Ceramics
Published: Date unknown
Authors: B W Steiner, L van den Berg, U Laor
Abstract: The hole mobility and carrier lifetime of [alpha] mercuric iodide high energy radiation detectors have been enhanced through crystal growth in microgravity. The improvement is closely correlated with specific characteristics of the crystal lattice, ...
