Level Crossings and Zero-Field Splitting in the Cr 8 }-Cubane Spin-cluster by Inelastic Neutron Scattering and Magnetization Studies

November 17, 2010
Author(s)
David Vaknin, V. O. Garlea, F. Demmel, E. Mamontov, H. Nojiri, C. Martin, I. Chiorescu, Yiming Qiu, P. Kogerler, J. Fielden, L. Engelhardt, M. Luban, M. Luban
Millikelvin inelastic neutron scattering in variable magnetic field and high-field magnetization measurements were performed to gain insight into the low-energy magnetic excitation spectrum and the field-induced level crossings in the molecular spin

Low temperature transport properties and heat capacity of single-crystal Na8Si46

November 17, 2010
Author(s)
Stevce Stefanoski, Joshua B. Martin, George S. Nolas
The low temperature thermal conductivity, resistivity, and Seebeck coefficient of single-crystal Na8Si46 are investigated revealing the intrinsic low temperature transport properties of this material. Metallic conduction is observed, with a higher residual

Modeling, Simulation and Analysis for Sustainable Product Development

November 17, 2010
Author(s)
Mahesh Mani, Bjoern J. Johansson, Kevin W. Lyons, Ram D. Sriram, Gaurav Ameta
Simulation plays a critical role in the design of products, materials and manufacturing processes. Increasingly, simulation is replacing physical tests to ensure product reliability and quality thereby facilitating steady reductions in design cycles

Developing Coverage Analysis for IFC Files

November 16, 2010
Author(s)
Robert R. Lipman
Conformance and interoperability testing of product data exchange interfaces is essential to delivering reliable software implementations and meeting user’s expectations for interoperability between BIM software. For either type of testing, product data

Fire Suppression

November 16, 2010
Author(s)
Cary Presser, Jiann C. Yang
Water sprinkler sprays (with relatively large droplet sizes) in residential and commercials structures are probably the most well known application of sprays in fire suppression. In more recent years, water mists (characterized by reduced droplet sizes

November 2010 SRM Spotlight

November 16, 2010
Author(s)
Regina R. Montgomery
The SRM Spotlight is a newsletter published by the Measurement Services Division for users of NIST standard reference materials. The Spotlight announces new reference materials and provides information about their use. In addition, this newsletter contains

SlapSegII Analysis: Matching Segmented Fingerprint Images

November 16, 2010
Author(s)
Craig I. Watson
This report is an extension of the SlapSegII evaluation and will study the affect of slap fingerprint segmentation on matching accuracy. This study will compare matching accuracy of hand marked segmentation data with the automated segmentation algorithms

A Portable Rubidium Fountain

November 15, 2010
Author(s)
Paul D. Kunz, Steven R. Jefferts, Thomas P. Heavner
We are developing a transportable laser-cooled rubidium (Rb) atomic fountain frequency standard. Over the last year we have built the Ramsey cavity and rubidium source oven and are preparing to assemble the physics package. We have also made numerous
