MALDI TOF MS Analysis of Chan End Functonalized Polymers

October 12, 2021
Author(s)
Kathleen M. Flynn, Barry J. Bauer, Kathryn Beers, S Bencherif, H M. Byrd, Sheng Lin-Gibson
Recently, we and other research laboratories have developed methods whereby an organic species is covalently attached to the polymer forming an organic salt to analyze by matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI

Manganese-Enhanced Magnetic Resonance Microscopy of Mineralization

October 12, 2021
Author(s)
I Chesnick, T Todorov, J M. Centeno, Dale Newbury, John A. Small, K Potter
Paramagnetic manganese (II) can be employed as a calcium surrogate to enhance the sensitivity of the magnetic resonance microscopy (MRM) technique to the processing of calcium during the bone formation process. At high doses, osteoblasts can take up

Manufacture of Al/SiC Metal Matrix Composites by the Press and Sinter Route

October 12, 2021
Author(s)
G T. Campbell, R Raman, Richard J. Fields
Aluminum based Metal Matrix Composites (MMC's) are being considered for many different high volume applications. The most common manufacturing rout for aluminum based MMC's is a blend/can/extrude route. This route is considered high cost and not

Manufacture of Extremely Flat 300 mm Silicon Wafers

October 12, 2021
Author(s)
Marc Tricard, Paul Dumas, Christopher Hall, Ulf Griesmann, Quandou (. Wang
The flatness requirement for silicon wafers at the exposure site will be lower than 50 nm by 2010 and may be as low as 25nm by 2015 (TRS 2005). This creates new challenges for both wafer polishing and metrology tools capable of meeting the specifications

Margin Failures in Brittle Dome Structures: Relevance to Failure of Dental Crowns

October 12, 2021
Author(s)
T Qasim, Chris Ford, M T. Bush, X Z. Hu, Kenneth Malament, Brian R. Lawn
Margin cracks in loaded brittle dome structures are investigated. Dome structures consisting of glass shells filled with polymer resin, simulating the essential features of brittle crowns on tooth dentin, provide model test specimens. Disk indenters of

Materials Data in the Internet Era - A Workshop on the Future

October 12, 2021
Author(s)
C P. Sturrock, J R. Rumble
In May 1999, ASTM E49 and the National Institute of Standards and Technology hosted a workshop in which over 100 international experts on materials data, materials databases and the Internet considered how ASTM can best serve the materials community with

MatML: XML for Information Exchange With Materials Property Data

October 12, 2021
Author(s)
A S. Varde, E F. Begley, S Fahrenholz-Mann
This paper describes the development and use of MatML, the Materials Markup Language. MatML is an emerging XML standard intended primarily for the exchange of materials property information. It provides a medium of communication for users in materials

Measurement of Nonlinear Phase Generated in Air-Silica Microstructure Fiber

October 12, 2021
Author(s)
T M. Fortier, Jun Ye, Steven T. Cundiff, R S. Windler
We present measurementsof the nonlinear phase noise generated in air-silica microstructure fiber, which is used in carrier envelope phase stabilization schemes for ultrafast lasers. The extreme nonlinearity exhibited by these fibers may result in amplitude
