Standards Development for Gas Phase Air Cleaning Equipment in Buildings

November 3, 2008
Author(s)
Andrew K. Persily, Cynthia H. Reed, Stephanie S. Watson, Nicos Martys, Edward J. Garboczi, Heather Davis
Concerns about building security have resulted in increasing interest in gas phase air cleaning (GPAC) and the need for standard methods to determine the effectiveness of these systems. Similarly, the ability to predict their installed performance, based

Comparing Analytical Methods for Detecting and Characterizing Nanoparticles in Formulated Products

October 1, 2008
Author(s)
Katherine M. Tyner, Anna M. Wokovich, William H. Doub, Lucinda F. Buhse, Li Piin Sung, Stephanie S. Watson, Nakissa Sadrieh
To understand the extent of consumer exposure to nanomaterials as well as how nanomaterials impact consumer goods, it is necessary to detect and characterize nanomaterials in unmodified final products. Although there are pathways to characterize

Elastic Modulus Characterization of Nanocomposite Latex Coatings

September 24, 2008
Author(s)
Aaron M. Forster, Stephanie S. Watson, Jonathan White
The elastic modulus of a polystyrene-butyl acrylate latex coating was measured using three different techniques: instrumented indentation, dynamic mechanical analysis, and tensile testing. The coating was formulated with 25 nm and 250 nm diameter TiO2

Contamination and Decontamination of Building Plumbing Systems

September 25, 2006
Author(s)
Stephen J. Treado, Mark A. Kedzierski, Stephanie S. Watson, Kenneth D. Cole
The quality of drinking water has always been a subject of interest. In fact, a stable and secure supply of clean drinking water is a hallmark of modern society. Recently, new concerns have arisen regarding the potential occurrence of intentional or

Mechanical Properties of Nanocomposite Latex Films via Instrumented Indentation

September 6, 2006
Author(s)
Aaron M. Forster, Stephanie S. Watson, Laura Johnson, Li Piin Sung
Inorganic particles, introduced into networked or glassy polymer films, have been used to increase the stiffness of films as a function of pigment loading. Latex films often contain inorganic pigments to increase the opaqueness of the film and to act as UV
