High Confidence Level Calibration for AFM Based Fracture Testing of Nanobeams

June 11, 2012
Author(s)
Scott Grutzik, Richard S. Gates, Yvonne B. Gerbig, Robert F. Cook, Melissa Hines, Alan Zehnder
When designing micro- or nanoelectromechanical systems, (MEMS and NEMS), it is important to consider whether structural elements will withstand loads experienced during operation. Fracture behavior at length scales present in MEMS and NEMS is much di erent

Electrochemical measurement of diffusion in photopolymerized polyethylene glycol (PEG) hydrogels

October 29, 2010
Author(s)
Kavita M. Jeerage, Stephanie M. LaNasa, Holly A. Hughes, Damian S. Lauria, Stephanie J. Bryant, Andrew J. Slifka
Scanning electrochemical microscopy has been used to examine the molecular transport properties of photopolymerized poly(ethylene glycol) (PEG) hydrogels having different mesh sizes. Both the molecular weight (508 Da or 3000 Da) of the PEG diacrylate

Covalent Attachment of Photoluminescent Silicon Nanoparticles to Streptavidin

September 11, 2007
Author(s)
Jonghoon Choi, Peter Niarhos, Nam S. Wang, Vytas Reipa
We have covalently attached multiple fluorescent silicon nanocrystals (SNs) to streptavidin molecule. Selective conjugation of SNs to a target protein is accomplished using sequential silicon surface termination chemistry. In the first step, freshly

Band 3 Modifications in Plasmodium Falciparum-Infected AA and CC Erythrocytes Assayed by Autocorrelation Analysis Using Quantum Dots

March 1, 2005
Author(s)
F Tokumasu, R M. Fairhurst, G R. Ostera, N J. Brittain, Jeeseong C. Hwang, T E. Wellems, J A. Dvorak
The molecular stability of hemoglobin is critical for normal erythrocyte functions, including oxygen transport. Hemoglobin C (HbC) is a mutant hemoglobin that has increased oxidative susceptibility due to an amino acid substitution ( 6: Glu to Lys). The

Validation of the Receprocity Law for Coating Photodegradation

October 20, 2004
Author(s)
Joannie W. Chin, Tinh Nguyen, Jonathan W. Martin, E Byrd
Accelerating the photodegradation of commerical polymeric materials has great practical importance in the weathering community. However, questions exist as to whether high radiant flux exposure results cn be extrapolated to in-service exposure levels

Microstructure-Property Correlations in Industrial Thermal Barrier Coatings

July 1, 2004
Author(s)
A Kulkarni, A N. Goland, H Herman, Andrew J. Allen, J Ilavsky, Gabrielle G. Long, C A. Johnson, J A. Ruud
This paper describes the results from multidisciplinary characterization/scattering techniques employed for the quantitative characterization of industrial thermal barrier coating (TBC) systems used in advanced gas turbines. While past requirements for

John S. Villarrubia, Andras Vladar, J R. Lowney, Michael T. Postek, Richard A. Allen, Michael W. Cresswell, Rathindra Ghoshtagore
… which is single crystal silicon with a buried insulating oxide, was measured using scanning electron microscopy (SEM) …

Dispersed Liquid Agent Fire Suppression Screen Apparatus

July 1, 1999
Author(s)
Jiann C. Yang, Michelle K. Donnelly, William L. Grosshandler, N C. Prive
The design, construction, demonstraion and operation of a bench-scale device capable of screening the fire suppression efficiency of liquid agents are described in detail in this report. The apparatus is based on a well-characterized flame, a means to
