Thermogravimetric Analysis with a Heated Quartz Crystal Microbalance

August 11, 2012
Author(s)
Ward L. Johnson, Elisabeth Mansfield
Thermogravimetric analysis with an SC-cut quartz crystal microbalance (QCM) were demonstrated at temperatures in the range from 20 C to 450 C. A measurement system was built around a crystal sensor head that was mounted in a small tube furnace. Changes in

Evaluating the characteristics of multiwall carbon nanotubes

July 1, 2011
Author(s)
John H. Lehman, M. Terrones, Elisabeth Mansfield, Katie Hurst, Vincent Muenier
During the past 20 years, multiwall carbon nanotubes (MWCNTs) have become an important industrial material. Hundreds of tons are produced each year. This review is a survey of the scientific literature, motivated by industrial requirements and guidelines

Effects of water quality parameters on the release of silver nanoparticles from a ceramic surface using a quartz crystal microbalance.

November 18, 2010
Author(s)
Michael Stewart, Angela R. Bielefeldt, Elisabeth Mansfield, R S. Summers, Joseph N. Ryan
Ceramic water filters are used in many developing countries as a household water treatment technology, often produced locally using regionally-available materials, and constructed in various forms (i.e., as discs, candles, or pots) that all rely on similar

Quartz crystal microbalance for in-situ monitoring of laser cleaning of carbon nanotubes

August 1, 2010
Author(s)
Katie Hurst, Abram Van Der Geest, Mark T. Lusk, Elisabeth Mansfield, John H. Lehman
Photochemical changes of single-walled carbon nanotubes (SWCNTs), graphite and amorphous carbon have been investigated with a quartz crystal microbalance (QCM). The method of in-situ measurements reduces our uncertainty that is attributable to

Quartz Crystal Microbalances for Microscale Thermogravimetric Analysis

June 20, 2010
Author(s)
Elisabeth Mansfield, Aparna Kar, Stephanie A. Hooker
A new method for analyzing the chemical purity and consistency of microscale samples is described using a quartz crystal microbalance (QCM) sensor platform. The QCM is used to monitor sub-picogram changes in the mass of a deposited thin film as a function
