A synchrotron beamline for extreme-ultraviolet photoresist testing

September 30, 2011
Author(s)
Charles S. Tarrio, Steven E. Grantham, Shannon B. Hill, Nadir S. Faradzhev, Lee J. Richter, Chester Knurek, Thomas B. Lucatorto
Before being used in an extreme-ultraviolet (EUV) scanner, photoresists must first be evaluated for sensitivity and tested to ensure that they will not contaminate the scanner optics. The new NIST facility described here provides data on the contamination

Compressed-Liquid Density Measurements of Methyl Oleate and Methyl Linoleate

September 30, 2011
Author(s)
Stephanie L. Outcalt
Compressed liquid densities of the fatty acid methyl esters methyl linoleate and methyl oleate have been measured with a vibrating-tube densimeter. The temperature and pressure range of the measured data is from 270 K to 470 K, and 0.5 MPa to 50 MPa. The

Decoherence, Autler-Townes effect, and dark states in two-tone driving of a three-level superconducting system

September 30, 2011
Author(s)
Jian Li, G.S. Paraoanu, Katarina Cicak, Fabio Altomare, Jae Park, Raymond Simmonds, Mika A. Sillanpaa, Pertti Hakonen
We present a detailed theoretical and experimental study of a multi-level quantum system coupled to two radiation ¯elds and subject to decoherence. We concentrate on an e®ect known from quantum optics as the Autler-Townes splitting, which has been recently

Information Security Continuous Monitoring (ISCM) for Federal Information Systems and Organizations

September 30, 2011
Author(s)
Kelley L. Dempsey, L A. Johnson, Matthew A. Scholl, Kevin M. Stine, Alicia Clay Jones, Angela Orebaugh, Nirali S. Chawla, Ronald Johnston
The purpose of this guideline is to assist organizations in the development of a continuous monitoring strategy and the implementation of a continuous monitoring program providing visibility into organizational assets, awareness of threats and

ROADMAPPING MANUFACTURING NEEDS FOR MEMS TECHNOLOGIES

September 30, 2011
Author(s)
Michael Gaitan, Karen Lightman
This report summarizes issues in manufacturing from the 2011 iNEMI MEMS Technology Roadmap, and shares the authors’ observations from the 2011 MEMS Industry Group’s (MIG) Workshop on Device Testing and the 2012 ITRS MEMS Technology Working Group’s (TWG)

The Evolution of Time Measurement, Part 2 - Quartz Clocks

September 30, 2011
Author(s)
Michael Lombardi
A historical article about the origins and the development of quartz clocks and oscillators (Part II of a IV-part series). It describes the discovery of piezoelectricity, the development of the first quartz oscillators, how quartz oscillators were

5754 Aluminum Sheet Deformed Along Bi-Linear Strain Paths

September 29, 2011
Author(s)
Mark A. Iadicola, Lin Hu, Anthony D. Rollett, Timothy J. Foecke
Sheet specimens of aluminum alloy 5754 were deformed along a series of bi-linear, equal-biaxial and uniaxial, strain paths while simultaneously measuring stress-strain behavior. Using the measured crystallographic texture before and after deformation, the

Reexamination of the C2H3+ microwave and infrared spectra

September 29, 2011
Author(s)
Jon T. Hougen, Laurent H. Coudert
The high-resolution infrared spectrum of C2H3 recorded in the 3 CH stretching region (J. Phys. Chem. 99 (1995) 15611-15623) is re-analyzed using an effective internal axis method (IAM) accounting for the large amplitude hydrogen migration motion. The

Service Life Prediction for Sealants

September 29, 2011
Author(s)
Christopher C. White, Donald L. Hunston, Kar T. Tan, James J. Filliben
Previous industry consensus postulated that four elements of the weather: Temperature, Humidity, Ultraviolet Radiation, and Mechanical loading were responsible for the majority of the changes observed in sealants exposed to outdoor weathering. The NIST

Distributed Deployment Algorithms for Improved Coverage in Mobile Sensor Networks

September 28, 2011
Author(s)
Vladimir V. Marbukh, Kamran Sayrafian, Hamid Mahboubi, Kaveh Moezzi, Amir G. Aghdam
In this paper, various sensor deployment strategies are studied for effective coverage in wireless sensor networks. In the proposed algorithms, each sensor discovers the coverage holes within its Voronoi polygons, and then moves in a proper direction to

Impact of Porous Media Grain Size on the Transport of Multiwalled Carbon Nanotubes

September 28, 2011
Author(s)
Nikolai Mattison, Denis O'Carroll, R. K. Rowe, Elijah Petersen
Nanomaterials possess unique physical, electrical and chemical properties which make them attractive for use in a wide range of applications. Through their use and eventual disposal, nanomaterials may ultimately be released into the subsurface environment

Magnetic Excitations in the Geometric Frustrated Multiferroic CuCrO 2

September 28, 2011
Author(s)
M. Frontzek, J. T. Haraldsen, A. Podlesnyak, M. Matsuda, A. D. Christianson, R. S. Fishman, A. S. Sefat, Yiming Qiu, John R. Copley, S. Barilo, S. V. Shiryaev, G. Ehlers
In this paper detailed neutron scattering measurements of the magnetic excitation spectrum of CuCrO6d2^ in the ordered state below T N1 = 24.2 K are presented. The spectra are analyzed using a model Hamiltonian which includes interlayer-exchanged up to the

September 28, 2011
Author(s)
Sheetal S. Pai, Boualem Hammouda, Kunlun Hong, Danilo.C. Pozzo, Todd M. Przybycien, Robert D. Tilton
Covalent conjugation of poly(ethylene glycol) or "PEGylation" has proven an effective strategy to improvement pharmaceutical protein efficacy. Understanding the configuration of conjugated PEG chains is necessary to interpret the effect of PEG conjugation

The NIST Definition of Cloud Computing

September 28, 2011
Author(s)
Peter M. Mell, Timothy Grance
Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with
