Interoperability Test of IEEE 1451.5 Standard-Based Wireless Sensors

March 13, 2010
Author(s)
Kang B. Lee, Yuyin Song
The Institute of Electrical and Electronics Engineers (IEEE) 1451 standard provides plug-and-play capability of smart transducers (sensors and actuators). Plug-and-play is an important aspect of interoperability, which is the ability of two or more systems

Uncertainties in Electron Probe Microanalysis

March 12, 2010
Author(s)
Ryna B. Marinenko, Stefan D. Leigh
This tutorial discusses the importance of citing valid uncertainties when reporting analytical results and the need for a universally accepted approach for evaluating uncertainties. Today, the CIPM procedure has been accepted by numerous international

Grating-Enhanced Narrow-Band Spontaneous Parametric Down Conversion

March 10, 2010
Author(s)
Xiao Tang, Lijun Ma
We propose a new method to narrow the linewidth of entangled photons from spontaneous parametric down conversion incorporated with an internal Bragg grating. We study and show that it is a promising way to generate narrow-line entangled photons.

Manipulation of crystallinity boundary via process space investigations of pulsed laser deposited high-k HfO2-TiO2-Y2O3 combinatorial thin films

March 10, 2010
Author(s)
Jennifer L. Klamo, Peter K. Schenck, Peter G. Burke, Kao-Shuo Chang, Martin L. Green
Combinatorial library films of HfO2-TiO2-Y2O3, a high-k dielectric system, grown by pulsed laser deposition, exhibit visible boundary lines separating amorphous and crystalline phases. By changing processing space parameters, specifically substrate

Molecular Simulation Study of Anisotropic Wetting

March 10, 2010
Author(s)
Eric M. Grzelak, Vincent K. Shen, Jeffrey R. Errington
We study anisotropic wetting in systems governed by Lennard-Jones interactions. Molecular simulation is used to obtain the macroscopic contact angle a fluid adopts on face-centered-, body-centered-, and simple-cubic lattices with the (100), (110), or (111)

Theta-like specimen to determine tensile strength at the micro-scale

March 10, 2010
Author(s)
Michael S. Gaither, Frank W. DelRio, Richard S. Gates, Edwin R. Fuller, Robert F. Cook
Micro- and nano-electromechanical systems are typically formed via lithographic and etching processes that leave residual surface features, stresses, and chemistry that ultimately control component strength and device reliability. Here, we describe a new

Synthesis of Photoactive Magnetic Nanoparticles with Atomic Layer Deposition

March 8, 2010
Author(s)
Yun Zhou, David M. King, Jianhua Li, Kathryn S. Barrett, Ronald B. Goldfarb, Alan W. Weimer
Iron-based magnetic nanoparticles have been produced by decomposition of iron oxalate powder. The micron-sized iron oxalate powder was first ground using a cryogenic milling process. A titanium dioxide (TiO 2) thin film was then deposited on the

Thin lm dielectric microstrip kinetic inductance detectors

March 8, 2010
Author(s)
David P. Pappas, Jiansong Gao, Benjamin Mazin, Daniel Sank, Erik Lucero, John M. Martinis, Andrew Merrill, Sunil Golwala, David Moore, Jonas Zmuidzinas
Microwave Kinetic Inductance Detectors, or MKIDs, are a type of low temperature detector that exhibit intrinsic frequency domain multiplexing at microwave frequencies. We present theory and measurements on a new type of MKID based on a microstrip

Vertically Graded Anisotropy in Co/Pd Multilayers

March 8, 2010
Author(s)
Brian J. Kirby, Joseph E. Davies, Kai Liu, Shannon Watson, G. T. Zimanyi, Robert D. Shull, Paul A. Kienzle, Julie A. Borchers
It has been theoretically predicted that depth-grading the magnetic anisotropy in perpendicular magnetic media should reduce the field required to write data, without affecting the thermal stability. To study this prediction, we have produced a series of

Broadband Characterization of Individual Platinum Nanowires

March 7, 2010
Author(s)
Kichul Kim, Thomas M. Wallis, Paul Rice, Chin J. Chiang, Atif A. Imtiaz, Pavel Kabos, Dejan Filipovic
Conductivity and contact resistance of 100 nm and 250 nm diameter platinum (Pt) nanowires (NWs) are investigated computationally and experimentally. Finite element method based full-wave modeling and circuit simulations are used in conjunction with

Accelerator Surface Phase Associated with Superconformal Cu Electrodeposition

March 5, 2010
Author(s)
Thomas P. Moffat, Liang Yueh Ou Yang
Superconformal film growth is a key process in state-of-the-art Cu metallization of electronic devices. Superfilling of recessed surface features results from competition between electrolyte additives that accelerate or inhibit Cu electroplating. In situ

Smoke Aerosol Measuremen Experiment (SAME)

March 5, 2010
Author(s)
Jiann Yang, Thomas Cleary, D L. Urban, Gary A. Ruff, William Sheredy, Zeng-guang Yuan, G W. Mulholland
This is the final report of a research project entitled Smoke Aerosol Measurements Experiment (SAME). Smoke and/or fire detection in the spacecraft is crucial to the success of future long term space travel. It has been realized that the gravity force

Low-loss superconducting resonant circuits using vacuum-gap -based microwave components

March 4, 2010
Author(s)
Katarina Cicak, Dale Li, Joshua Strong, Michael S. Allman, Fabio Altomare, Adam J. Sirois, Jed D. Whittaker, Raymond W. Simmonds
We have produced high quality resonant microwave circuits through developing a vacuum-gap technology for fabricating lumped-element capacitive and inductive components. We use micromachining to eliminate amorphous dielectric materials leaving vacuum in

Diffusion-controlled reference material for VOC emissions testing: proof of concept

March 3, 2010
Author(s)
Steve Cox, Zhe Liu, John Little, Cynthia H. Reed, Steven J. Nabinger, Andrew K. Persily
Because of concerns about indoor air quality, there is growing awareness of the need to reduce the rate at which indoor materials and products emit volatile organic compounds (VOCs). To meet consumer demand for low emitting products, manufacturers are

Energy dissipation of highly charged ions on Al oxide films

March 3, 2010
Author(s)
Joshua M. Pomeroy, Russell Lake, C E. Sosolik
Slow highly charged ions carry a large amount of potential energy that can be dissipated within femtoseconds upon interaction with a surface. HCI-insulator collisions result in high sputter yields and surface nano-feature creation due to strong coupling

Matrix Relaxation After Fracture In A Toughened Epoxy

March 3, 2010
Author(s)
Aaron M. Forster, Aurelien Blond, Donald L. Hunston
The inclusion of phase-separated rubber particles in a brittle thermoset matrix has been shown to increase the Mode I fracture energies for a wide range of model and commercial adhesives. Our recent efforts combine these two approaches by comparing the

Measurement Challenges in Achieving Energy Monitoring Systems in Buildings
