391. The Effects of Humidity and Surface Free Energy on Adhesion Force between AFM Tip and a Silane Self-Assembled Monolayer Film
Topic: Materials Science
Published: 2/17/2010
Authors: Chien-Chao Huang, Lijiang Chen, , Xiaohong Gu, Minhua Zhao, Tinh Nguyen, Sanboh Lee
Abstract: The relationship between AFM probe-sample adhesion force and relative humidity (RH) at five different levels of surface free energy (γs) of an organic self-assembled monolayer (SAM) has been investigated. Different γs levels were achieved b ...

392. The Influence Of Hydrogen On The Elastic Modulus And Anelastic Response Of Cold Worked Pure Iron
Topic: Materials Science
Published: 7/1/2009
Authors: Richard E Ricker, David J Pitchure
Abstract: Understanding the influence of hydrogen on elastic deformation and anelastic response should contribute to our understanding of the influence of hydrogen on deformation and fracture. To accomplish this objective, samples of pure iron were cold-worked ...

393. The Influence of Matrix and LaserEnergy on the Molecular MassDistribution of Synthetic Polymers Obtained by MALDI-TOF-MS
Topic: Materials Science
Published: Date unknown
Authors: S Wetzel, Charles Martin Guttman, J. Girard
Abstract: The molecular mass distribution (MMD) obtained in synthetic polymer characterization by matrix-assisted laser desorption/ionizationtime-of-flight mass spectrometry (MALDI-TOF-MS) may be biased by preferential desorption/ionization of low mass polymer ...

Topic: Materials Science
Published: 5/3/1999
Author: Thomas Allen Siewert
Abstract: Commission V covers issues of weld inspection and quality control for the International Institute of Welding (IIW). This report summarizes the information presented at the 1998 Annual Assembly: descriptions of both research and draft ISO standards b ...

395. The Recovery of Elastic Properties at 35 C in Trip 700 Steel Following Deformation
Topic: Materials Science
Published: 6/1/2007
Authors: David J Pitchure, Richard E Ricker
Abstract: The influence of plastic deformation on the elastic properties that determine the magnitude of springback following forming was investigated using dynamic modulus analysis. For this study, the elastic modulus of TRIP 700 steel was measured continuou ...

396. The Role of Folding in the Degradation of Ballistic Fibers
Topic: Materials Science
Published: 8/2/2010
Authors: Gale Antrus Holmes, Walter G McDonough, Jae Hyun Kim, Derek Li-Te Ho
Abstract: Failures of certified soft body armor led to a call to understand the underlying mechanisms of the failure. Research has indicated that the folding of ballistic fibers comprising the soft body armor may be a factor in the performance deterioration t ...

397. The effect of thermal oxidation on laser-induced photoelectron emission during tensile deformation of polycrystalline aluminum
Topic: Materials Science
Published: 4/1/2010
Authors: M Cai, S C Langford, Richard E Ricker, Lyle E Levine, J T Dickinson
Abstract: Many metals emit electrons when exposed to UV radiation from excimer lasers (photon energies 4 eV to 8 eV). Deformation can significantly affect the intensity of these emissions. In the case of reactive metals, these emissions are also altered by t ...

398. The effect of urban trees on the rental price of single-family homes in Portland, Oregon
Topic: Materials Science
Published: 8/1/2011
Authors: Geoffrey Donovan, David T Butry
Abstract: Few studies have estimated the effect of environmental amenities on the rental price of houses. We address this gap in the literature by quantifying the effect of urban trees on the rental price of single-family homes in Portland, Oregon. We found th ...

399. The molecular basis of mesophase ordering in a thiophene-based copolymer
Topic: Materials Science
Published: 2/18/2009
Authors: Dean M DeLongchamp, Regis J Kline, Youngsuk Jung, Eric K Lin, Daniel A Fischer, David J Gundlach, Andrew Moad, Lee J Richter, Michael F. Toney, Martin Heeney, Iain McCulloch
Abstract: The carrier mobility of poly(2,5-bis(3-alkylthiophen-2-yl) thieno[3,2-b]thiophene) semiconductors can be substantially enhanced after heating through a thermotropic mesophase transition, which causes a significant improvement in thin film structural ...

400. The value of shade: Estimating the effect of urban trees on summertime electricity use
Topic: Materials Science
Published: 6/1/2009
Authors: Geoffrey Donovan, David T Butry
Abstract: We estimated the effect of shade trees on the summertime electricity use of 640 single-family homes in Sacramento, California. Results show that trees on the west and south sides of a house reduce summertime electricity use, whereas trees on the nort ...
