Aggregation/agglomeration state of carbon nanotubes

October 12, 2012
Author(s)
Vivek M. Prabhu, Toshiya Okazaki, Takeshi Eitoku, Masayoshi Tange, Haruhisa Kato
Evaluation of aggregation and agglomeration of carbon nanotube (CNT) solution has been one of the key issues for applications. Here we introduce a simple method based on depolarized dynamic light scattering (DDLS) performed at multiple scattering angles to

Automated Multiprobe Microassembly using Vision Feedback

October 5, 2012
Author(s)
John D. Wason, John T. Wen, Jason J. Gorman, Nicholas Dagalakis
This paper describes the algorithm development and experimental results of a vision-guided multi-probe microassembly system. The key focus is to develop the capabilities required for the construction of three dimensional (3D) structures using only planar

Spin Dynamics in the Time and Frequency Domain

September 15, 2012
Author(s)
Thomas J. Silva
The current status of experimental approaches to analyze the spin wave dynamics in ferromagnetic nanoscale structures is reviewed. Recent developments in frequency- and field swept spectroscopy to determine the resonant response of nanoscale ferromagnets

UV-induced photochemical transformations of citrate capped silver nanoparticle suspensions

September 14, 2012
Author(s)
Justin M. Gorham, Robert I. MacCuspie, Kate L. Klein, D H. Fairbrother, Richard D. Holbrook
Due to the increasing use of silver nanoparticles (AgNPs) in consumer products, it is essential to understand how variables, such as light exposure, may change the physical and chemical characteristics of AgNP suspensions. To this end, the effect of 300 nm

Evaluation of viability and proliferation profiles on macrophages treated with silica nanoparticles in vitro via plate-based, flow cytometry, and Coulter counter assays

September 3, 2012
Author(s)
Simona Bancos, De-Hao D. Tsai, Vincent A. Hackley, J L. Weaver, Katherine M. Tyner
Nanoparticles (NPs) are known to interfere with many high throughput cell viability and cell proliferation assays, which complicates the assessment of their potential toxic effects. The aim of this study was to compare viability and proliferation results

Characterization of Surface Accumulation and Release of Nanosilica During Irradiation of Polymer Nanocomposites with Ultraviolet Light

August 12, 2012
Author(s)
Tinh Nguyen, Bastien T. Pellegrin, Coralie Bernard, Savelas A. Rabb, Paul E. Stutzman, Justin M. Gorham, Xiaohong Gu, Lee L. Yu, Joannie W. Chin
Nanofillers are increasingly used for enhancing multiple properties of polymeric materials in many applications. However, polymers are susceptible to photodegradation by solar ultraviolet (UV) radiation Therefore, nanofillers in a polymer nanocomposite

Summary Report of Research on TiO2 Nanomaterial

August 3, 2012
Author(s)
Vincent A. Hackley
Report summarizes study whose purpose was to optimize and validate a standardized and reproducible approach for the preparation of TiO2 nanoparticle dispersions in relevant biological and environmental test media, using an industrially relevant powder form
