Universal scaling law for the flow of non-Newtonian colloidal suspension

October 1, 2014
Author(s)
Nicos Martys, William L. George, Maxime Liard, Pascal Hebraud, Didier Lootens
It has been observed that flow curves (viscosity vs shear-rate) of spherical non-colloidal particles suspended in a non-Newtonian fluid matrix can be rescaled so as to collapse onto the flow curve of the matrix fluid. This result is surprising given the

Roadmap for Building Commissioning Research Workshop Summary Report

September 30, 2014
Author(s)
Natascha S. Milesi-Ferretti, David Shipley, Walter Zalis, Steven T. Bushby
This report summarizes the results of the Building Commissioning Research and Measurement Science Needs Webinar Workshop held on April 29, 2014, sponsored by the National Institute of Standards and Technology. This effort supports ongoing research into

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 Reneke, Richard D. 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
