Can We Get 3D CD Metrology Right?

April 19, 2012
Author(s)
Andras Vladar, John S. Villarrubia, Michael T. Postek, Petr Cizmar
Our world is three-dimensional, so are the integrated circuits (ICs), they have always been. In the past, for a long time, we’ve been very fortunate, because it was enough to measure the critical dimension (CD), the width of the resist line to keep IC

Cross-sectional stability of structural steel at elevated temperatures

April 19, 2012
Author(s)
Therese P. McAllister, Mina S. Seif
There is a lack of understanding of how structural systems perform under realistic, uncontrolled fires. Current specifications for the design of steel structures in the US do not include fire effects as part of structural design. Instead, fire protection

Structure of [C 4 mpyr][NTf 2 ] Room-Temperature Ionic Liquid at Electrified Gold Interfaces

April 19, 2012
Author(s)
Yansen Lauw, Michael D. Horne, Theo Rodopoulos, Vera Lockett, Bulent Akgun, William A. Hamilton, Andrew R. J. Nelson
The structure of l-butyl=l-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide ([C 4mpyr][NTf 2]) room-temperature ionic liquid at an electrified gold interface was studied using neutron reflectometry, cyclic voltammetry, and differential capacitance

Web-enabled, Real-time, Quality Assurance for Machining Production Systems

April 19, 2012
Author(s)
John L. Michaloski
In order to maintain the close control of production quality, frequent measurement and process parameter adjustments are desirable. In the discrete parts industry, part inspection is intended to be a metric for the process quality but quality control is

IREX III Supplement 1: Failure Analysis

April 18, 2012
Author(s)
George W. Quinn, Patrick J. Grother
Iris recognition has the potential to be extremely accurate, but it is highly dependent on the quality of the input data. Iris occlusion, off-axis gaze, blurred images, and iris rotation are common problems that can make recognizing individuals more

Strategic Roadmap for Fire Risk Reduction in Buildings and Communities

April 18, 2012
Author(s)
Anthony P. Hamins, Jason D. Averill, Richard G. Gann, Nelson P. Bryner, Rick D. Davis, David T. Butry, Alexander Maranghides, Jiann C. Yang, Daniel M. Madrzykowski, Matthew F. Bundy, Samuel L. Manzello, Jeffrey W. Gilman, Francine K. Amon, William E. Mell
The burden of fire on the U.S. economy continues to be large, comprising approximately $280 billion annually, or 2 percent of GDP. Over the last 30 years, civilian fire deaths and injuries have decreased due to the efforts of many people and organizations

A Lectin-Based Gold Nanoparticle Assay for Probing Glycosylation of Glycoproteins

April 17, 2012
Author(s)
Germarie Sanchez-Pomales, Todd A. Morris, James Falabella, Michael J. Tarlov, Rebecca A. Zangmeister
We report a glycoanalysis method in which lectins are used to probe the glycans of glycoproteins that are adsorbed on gold nanoparticles. A model mannose-presenting glycoprotein, ribonuclease B (RNase B), and the therapeutic monoclonal antibody (mAb)

Band-Like Transport in Strongly-Coupled And Doped Quantum Dot Solids: A Route To High-Performance Thin-Film Electronics

April 17, 2012
Author(s)
Ji-Hyuk Choi, Aaron T. Fafarman, Soong J. Oh, Dong-Kyun Ko, David K. Kim, Benjamin T. Diroll, Shinichiro Muramoto, J Greg Gillen, Christopher Murray, Cherie R. Kagan
Artificial solids constructed from colloidal quantum dot (QD) building blocks promise materials with tunable electronic properties. Yet high carrier mobilities and conductivities have been limited by weak coupling and low carrier concentrations. We report

Magnetoencephalography with a chip-scale atomic magnetometer

April 17, 2012
Author(s)
Svenja A. Knappe, Tillman H. Sander, Jan Preusser, Rahul R. Mhaskar, John E. Kitching, Lutz Trahms
We report on the measurement of somatosensory-evoked and spontaneous magnetoencephalography signals with a chip-scale atomic magnetometer. This uncooled, fiber-coupled sensor has a sensitive volume of 0.58 mm 3 inside a sensor head of volume 1 cm 3. When
