The DNA Damaging Potential of Photoactivated P25 Titanium Dioxide Nanoparticles

September 30, 2014
Author(s)
Elijah Petersen, Vytas Reipa, Stephanie S. Watson, Deborah Jacobs, Savelas A. Rabb, Bryant C. Nelson
Titanium dioxide nanoparticles (TiO2 NPs) are found in numerous commercial and personal care products. Thus, it is necessary to understand and characterize their potential environmental health and safety risks. It is well known that photoactivated TiO2 NPs

CURVED-WIDE PLATE TESTING OF X100 GIRTH WELDS

September 29, 2014
Author(s)
Timothy S. Weeks, Joseph D. McColskey, Mark D. Richards, Yong-Yi Wang, Marie A. Quintana
The curved-wide plate (CWP) tests are frequently used for assessing the quality of pipeline girth welds. Despite a large number of CWP tests having been conducted at great expense over many decades, an industry consensus standard remains unavailable

In-situ morphology studies of the mechanism for solution additive effects on the formation of bulk heterojunction films.

September 29, 2014
Author(s)
Lee J. Richter, Dean M. DeLongchamp, Kang W. Chou, Aram Amassian, A Hexemer, Eric Schaible, Felicia A. Bokel, Sebastian Engmann
The most successful active film morphology in organic photovoltaics is the bulk heterojunction (BHJ). The performance of a BHJ arises from a complex interplay of the spatial organization of the segregated donor and acceptor phases and the local order

Testing of Small-Sized Specimens

September 26, 2014
Author(s)
Enrico Lucon
An extensive review of the current state-of-the-art of small specimen test technology (SSTT) has been presented, covering a number of experimental techniques aimed at characterizing the mechanical properties of materials and components through the use of

A Review of Risk Perception in Building Fire Evacuation

September 25, 2014
Author(s)
Max Kinateder, Erica D. Kuligowski, Paul A. Reneke, Richard Peacock
Risk perception (RP) is studied in many research disciplines (e.g., safety engineering, psychology, and sociology), and the context in which RP is studied varies greatly. Definitions of RP can be broadly divided into expectancy- value and risk-as-feeling

Assessing technical performance in differential gene expression experiments with external spike- in RNA control ratio mixtures

September 25, 2014
Author(s)
Sarah A. Munro, Steven P. Lund, Patrick S. Pine, Hans Binder, Djork-Arne Clevert, Ana Conesa, Joaquin Dopazo, Mario Fasold, Sepp Hochreiter, Huixao Hong, Nederah Jafari, David P. Kreil, Pawel P. Labaj, Yang Liao, Simon Lin, Christopher E. Mason, Javier Santoyo, Steven J. Schrodi, Leming Shi, Wei Shi, Gordon K. Smyth, Nancy Stralis-Pavese, Zhenqiang Su, Charles Wang, Jian Wang, Joshua Xu, Zhan Ye, Yong Yang, Ying Yu, Paul Zumbo, Marc L. Salit
There is a critical need for standard approaches to assess, report and compare the technical performance of genome-scale differential gene expression experiments. Here we assess technical performance with a proposed standard ‘dashboard’ of metrics derived

Draft B Report of Bilateral Key Comparison SIM.T-K6.2 on Humidity Standards In the Dew/Frost-point Temperature Range from -20 degC to 20 degC

September 25, 2014
Author(s)
Christopher W. Meyer, Peter H. Huang, Enrique Martines-Lopez, Edgar Mendez-Lango, Jesus Davila Pacheco
A Regional Metrology Organization (RMO) Key Comparison of dew/frost point temperatures TDP/FP was carried out by NIST and the Centro Nacional de Metrologia (CENAM, México) between July, 2008 and December, 2008. This report presents the results of this

GaN nanowire coated with atomic layer deposition of tungsten: a probe for near-field scanning microwave microscopy

September 25, 2014
Author(s)
Joel Weber, Paul T. Blanchard, Aric Sanders, Jonas Gertsch, Steven George, Samuel Berweger, Atif A. Imtiaz, Thomas Mitchell (Mitch) Wallis, Kris A. Bertness, Pavel Kabos, Norman A. Sanford, victor bright
We report on the fabrication of a GaN nanowire probe for near-field scanning microwave microscopy. The probe has a capacitive resolution of 0.03 fF, surpassing that of a commercial Pt tip. Imaging of MoS2 sheets found the probe to be immune to surface
