Effects of Polymorphism on Charge Transport in Organic Semiconductors

August 3, 2009
Author(s)
Oana Jurchescu, M. Devin, Sankar Subramanian, Sean R. Parkin, Brandon Vogel, John E. Anthony, Thomas Jackson, David J. Gundlach
The increasing interest in fluorinated 5,11-bis(triethylsilylethynyl)anthradithiophene (diF TES ADT) is motivated by the demonstrated high performance field-effect transistors and circuits based on this material, complemented by reduced complexity

Impact of automation on precision

August 3, 2009
Author(s)
M A. Donmez, Johannes A. Soons
Automation has significant impacts on the economy and the development and use of technology. In this section, the impacts of automation on precision, which directly influences science, technology, and the economy, are discussed. As automation enables

Nanoscale Contacts Form the Bridge for Nano-Electrotechnical Businesses

August 3, 2009
Author(s)
Herbert S. Bennett
The purpose of this paper is to suggest a possible framework for nanoscale contacts that the stakeholders in nano-electrotechnologies may follow to establish international standards with the goal of accelerating innovation in nano-electrotechnologies

REFERENCE MATERIALS FOR RHEOMETERS AND THE FLOW TABLE

August 3, 2009
Author(s)
Chiara F. Ferraris, Zughuo Li, Mona Mohseni, Nicholas Franson
Oil is the most used standard material for the calibration of rheometers. Other products are used to calibrate flow devices, i.e., the flow table is calibrated using a mixture of oil and silica powder. The oil is a Newtonian liquid while the oil-silica

Tracking down sources of carbon contamination in EUVL exposure tools

August 3, 2009
Author(s)
Charles S. Tarrio, Robert E. Vest, Thomas B. Lucatorto, R. Caudillo
Optics in EUVL exposure tools are known to suffer reflectivity degradation, mostly from the buildup of carbon. The sources of this carbon have been difficult to identify. Vacuum cleanliness is normally monitored with a residual gas analyzer, but this has

TRC Thermodynamic Tables, Non-Hydrocarbons Supplement NH-101

August 3, 2009
Author(s)
Michael D. Frenkel
1. Table 23-2-1-(9.32000)-d, Pages d-6376.0 through d-6376.1: New table for cyclic carbonates, C3 to C5, for the condensed phases at one bar, or at equilibrium vapor pressure above the boiling point. 2. Table 14-2-(1.01000)-db, Pages db-290.0 through db

Long distance frequency transfer through an optical carrier

August 2, 2009
Author(s)
Paul A. Williams
Fiber optic networks are an attractive means for the remote distribution of highly stable frequencies from optical clocks. The highest performance is achieved by use of the frequency of the optical carrier itself as the transfer frequency. We will review

A mechanistically relevant cytotoxicity assay based on the detection of cellular GFP

August 1, 2009
Author(s)
Michael W. Halter, Jamie L. Almeida, Alessandro Tona, Kenneth D. Cole, Anne L. Plant, John T. Elliott
Cell-based assays for measuring ribosome inhibition by proteins such as the plant toxin ricin are important for characterizing decontamination strategies and developing detection technologies for field use. We report here an assay for ricin that provides a

Establishment of the SIM Time Scale

August 1, 2009
Author(s)
J. Mauricio Lopez-Romero, N. Munoz, Michael A. Lombardi
The SIM time and frequency metrology working group has developed a comparison network for the Americas, with the goals of improving metrology in the SIM region and to allow as many countries as possible to participate in the network. As of May 2008, ten

From the Editor's Desk: Diversity in Publications

August 1, 2009
Author(s)
Catherine A. Remley
This is an Editorial for the August, 2009 issue of IEEE Microwave Magazine. Kate Remley, the Editor-in-Chief, writes about timely topics for the members of the Microwave Theory and Techniques Society (MTT-S).

High Definition Flow

August 1, 2009
Author(s)
John D. Wright, Michael R. Moldover
From pharmaceutical production to the natural gas market, exact flow measurements are critical. Here's how NIST helps keep us all on the same page.

MEMS in Action: RoboCup Nanogram 2009

August 1, 2009
Author(s)
Richard A. Allen, Craig D. McGray
From June 29 through July 5, 2009 teams from around the world participated in the International RoboCup competition, held in Graz, Austria. In addition to humanoid robots playing soccer on turf fields, companion robots demonstrating their ability to help

Radiation-Based Quantitative Bioimaging at NIST

August 1, 2009
Author(s)
Lisa R. Karam
The National Institute of Standards and Technology (NIST) provides the physical measurements and standards in a variety of fields, including for ionizing radiation, for the US. Building on a long history of providing standards for medical x rays and

Stylus ion trap for enhanced access and sensing

August 1, 2009
Author(s)
Robert Maiwald, Gerd Leuchs, Dietrich Leibfried, Joseph W. Britton, James C. Bergquist, David J. Wineland
We experimentally characterized a novel radio-frequency (rf) ion trap geometry formed by two concentric cylinders over a ground plane. These traps allow for optical and physical access over more than 2 pi solid angle reaching 91% and 96% of 4 respectively
