Dynamic contact AFM methods for nanomechanical properties

December 1, 2013
Author(s)
Donna C. Hurley, Jason P. Killgore
This chapter focuses on two atomic force microscopy (AFM) methods for nanomechanical characterization: force modulation microscopy (FMM) and contact resonance (CR) techniques. FMM and CR methods share several common features that distinguish them from

High-Temperature Electromechanical Properties of CTGS

December 1, 2013
Author(s)
Ward L. Johnson, Michal Schulz, Holger Fritze
CTGS (Ca3TaGa3Si2O14) is a commercially available, Czochralski-grown piezoelectric material from the langasite family that has an ordered crystal structure. It can be excited piezoelectrically up to at least 1285 °C, which is very close to the melting

Micelle size effect on Fe-55 Liquid Scintillation Efficiency

December 1, 2013
Author(s)
Denis E. Bergeron, Lizbeth Laureano-Perez
We used efficiency tracing techniques to study the micelle size effect on liquid scintillation counting of the low-energy Auger electron emitter, 55Fe. We determined micelle hydrodynamic diameters for specific LS cocktails via dynamic light scattering, and

Optical Atomic Clocks

December 1, 2013
Author(s)
Christopher W. Oates, N Poli, P. Gill, G.M. Tino
In the last ten years extraordinary results in time and frequency metrology have been demonstrated. Frequency stabilization techniques for continuous wave lasers and femto-second optical frequency combs have enabled a rapid development of frequency

Practical CFD Simulations of Wind Tunnel Tests

December 1, 2013
Author(s)
Dilip K. Banerjee, Scott Hemley, Randall J. McDermott, Donghun Yeo, Marc L. Levitan
Computational fluid dynamics (CFD) has the potential of replacing wind tunnel testing in many wind engineering applications. Validated CFD software could enable structural engineers and builders to calculate wind effects on buildings for which no

Pressure-Sensitive Sampling Wands for Homeland Security Applications

December 1, 2013
Author(s)
Matthew E. Staymates, Jennifer R. Verkouteren, Jessica Grandner
This work discusses the use of Force Sensing Resistor (FSR) technology for Homeland Security applications. One area of particular focus is the optimization of wipe sampling of surfaces to facilitate enhanced trace contraband collection. Another focus area
