Surface Engineering Measurement Standards for Inorganic Materials

April 14, 2005
Author(s)
S J. Dapkunas
The Recommended Practice Guide describes nearly 200 standard measurement methods (standards) used by the surface engineering community. The standards compiled address inorganic (metal and ceramic) materials used in structural applications. The Guide is

Genetic Cellular Responses to Tyrosine-Derived Polycarbonate Blends

April 1, 2005
Author(s)
L A. Bailey, Matthew Becker, James A. Cooper, J Kohn, Eric J. Amis
The evaluation and identification of detrimental interactions between biological species and synthetic surfaces is a daunting challenge as the number of materials and control of physical variables increases. In this talk, the physical properties of

Manipulating Cell Adhesion on Gradient Poly(2-Hydroxyethyl Methacrylate)-Grafted Surfaces

April 1, 2005
Author(s)
Ying Mei, Tao Wu, Chang Xu, K J. Langenbach, John T. Elliott, B D. Vogt, Kathryn L. Beers, Eric J. Amis, N Washburn
In this study, a simple and versatile method was developed to prepare the low grafting density initaitor gradient, which was combined with surface initiated atom transfer radical polymerizations (ATRP) to produce a well defined poly(2-hydroxyethyl

Microfluidic Platform for the Generation of Organic-Phase Microreactors

April 1, 2005
Author(s)
Zuzanna T. Cygan, J Cabral, Kathryn L. Beers, Eric J. Amis
Rapid prototyping photolithography of a thiolene based resin was used to fabricate microfluidic devices stable to aliphatic and aromatic organic solvents. The swelling of the thiolene resin in various organic solvents was quantified and the solvent

Boundary Lubricating Film: Formation and Lubrication Mechanism

March 4, 2005
Author(s)
Stephen M. Hsu, Richard S. Gates
Boundary lubricating films are critical in effective lubrication of engine components. Their formation mechanism has not been fully understood because of the large variations of chemistry and machinery in operation. Various reports on boundary lubricating

Boundary Lubrication and Boundary Lubricating Film

March 3, 2005
Author(s)
Stephen M. Hsu, Richard S. Gates
This chapter offers a comprehensive summary of current understanding in boundary lubrication and the formation of boundary lubricating films. Classical and modern definitions of boundary lubrication are presented which serve to define the scope of boundary

Photoreflectance Study of the Electronic Structure of Si-Doped InyGa 1-y As 1-x N x Films With x

March 1, 2005
Author(s)
Youn S. Kang, Lawrence H. Robins, Anthony Birdwell, Alexander J. Shapiro, W. R. Thurber, Mark D. Vaudin, M M. Fahmi, D Bryson, S N. Mohammad
The electronic structure of Si-doped InyGa1-yAs1-xNx films on GaAs substrates, grown by nitrogen-plasma-assisted MBE, was examined by photoreflectance (PR) spectroscopy at temperatures between20 K and 300 K. The measured critical-point energies were

Combinatorial Peel Tests for the Characterization of Adhesion Behavior of Polymeric Films

February 1, 2005
Author(s)
R Song, Martin Chiang, A J. Crosby, Alamgir Karim, Eric J. Amis, Naomi Eidelman
The self-adhesion behavior of an optically smooth poly(methyl methacrylate) (PMMA) thin film (ca.. 100 nm) on different evaporated metal substrates has been investigated using a combinatorial method approach. In this investigation through high-throughput

Generation of Lattice Wannier Functions via Maximum Localization

January 20, 2005
Author(s)
Eric J. Cockayne
A method is presented for generating approximate lattice Wannier functions (LWF) for lattice dynamics problems, using the dynamical matrix for a supercell as input. The lattice Wannier functions fit selected phonon frequencies and eigenvectors exactly, are

Investigation of the Charge Compensation Mechanism on the Electrochemically Li-Ion Deintercalated Li 1-x Co 1/3 Ni 1/ 3MN 1/3 O 2 Electrode System by Combination of Soft and Hard X-Ray Absorption Spectroscopy

January 11, 2005
Author(s)
W S. Yoon, Kyung Y. Chung, Xiao-Qing Yang, James McBreen, Mahalingam Balasubramanian, C P. Grey, Daniel A. Fischer
In situ hard X-ray absorption spectroscopy (XAS) at metal K-edges and soft XAS at O K-edge and metal L-edges have been carried out during the first charging process for the layered Li1-2Co1/3Ni1/3Mn1/3O2 cathode material. The metal K-edge XANES results

Bioactive Surface Gradients to Control Cell Adhesion

January 1, 2005
Author(s)
Matthew Becker, Nathan D. Gallant, Eric J. Amis
Incorporating discrete cell adhesion motifs onto substrates in a defined orientation with variable spacing and increasing concentration offers a robust strategy for measuring ligand dependent cell-material interactions and encouraging specific cell
