113. Temperature-Programmed Electrospray-Differential Mobility Analysis for Characterization of Ligated Nanoparticles in Complex Media
Topic: Characterization, Nanometrology, and Nanoscale Measurements
Published: 8/12/2013
Authors: De-Hao D. Tsai, Frank W DelRio, John M Pettibone, Pin Ann Lin, Jiaojie Tan, Michael Russel Zachariah, Vincent A Hackley
Abstract: In this study, an electrospray-differential mobility analyzer (ES-DMA) was operated with an aerosol flow-mode, temperature-programmed approach to enhance its ability to characterize the particle size distributions (PSDs) of nanoscale particles (NPs) ...

114. Temperature-dependent mechanical-resonance frequencies and damping in ensembles of gallium nitride nanowires
Topic: Characterization, Nanometrology, and Nanoscale Measurements
Published: 10/22/2012
Authors: Kristine A Bertness, Norman A Sanford, J. R. Montague, H.S. Park, Victor M. Bright, C. T. Rogers
Abstract: We have measured singly clamped cantilever mechanical-resonances in ensembles of as-grown gallium nitridenanowires (GaN NWs), from 12 K to 320 K. Resonance frequencies are approximately linearly dependent on temperature near 300 K ...

115. Three dimensional aspects of droplet coalescence during dropwise condensation on superhydrophobic surfaces
Topic: Characterization, Nanometrology, and Nanoscale Measurements
Published: 8/24/2011
Authors: Konrad Rykaczewski, John Henry j Scott, Sukumar Rajauria, W Robert Ashurst, Jeff Chinn, Amy Chinn, Wanda Jones
Abstract: We report formation of nano-to-microscale satellite droplets in the geometrical shadow of high contact angle primary drops during dropwise water condensation on a nanostructured superhydrophobic surface. The primary drops contribute to the heat tran ...

120. UV-induced photochemical transformations of citrate capped silver nanoparticle suspensions
Topic: Characterization, Nanometrology, and Nanoscale Measurements
Published: 9/14/2012
Authors: Justin M Gorham, Robert I. MacCuspie, Kate L Klein, D Howard Fairbrother, Richard D Holbrook
Abstract: 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 o ...
