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

Core-shell composite of SiCN and multiwalled carbon nanotubes from Toluene dispersion

May 21, 2010
Author(s)
John H. Lehman, Katherine E. Hurst, Gurpreet Singh, Elisabeth Mansfield, John D. Perkins, Christopher L. Cromer
Carbon nanotubes are known to have high thermal conductivity, and in bulk form, a topology that could constitute the matrix of an inhomogeneous solid. Among the promised applications of carbon nanotubes is a composite material that is practical for thermal

Tissue Engineered Scaffolds for Screening Nanoparticle - Cell Interactions

April 21, 2010
Author(s)
Kavita M. Jeerage, Elisabeth Mansfield, Tammy L. Oreskovic, Nikki S. Rentz, Timothy P. Quinn
Long-term studies of nanoparticle-cell interactions require an advanced tissue-like environment in which nanoparticles are encapsulated with a population of cells for real-time and end-point analysis. By using soft tissue-mimicking hydrogels, the cells are

Excimer laser-based purification of single-walled carbon nanotubes

April 1, 2010
Author(s)
Katie Hurst, Elisabeth Mansfield, Anne Dillon, John H. Lehman
Bulk purified carbon nanotube (CNT) material is essential for the realization of CNT applications including incorporating them into various composite materials. We have developed a laser-based purification technique for bulk single-walled carbon nanotubes

Multiwalled carbon nanotubes coated with silicon carbonitride (SiCN)

April 1, 2010
Author(s)
Katie Hurst, Christopher L. Cromer, Elisabeth Mansfield, Roop Mahajan, John H. Lehman, Gurpreet Singh
We describe the development of two next-generation optical coatings; amorphous polymer-derived silicon carbonitride (SiCN) particles and a composite consisting of SiCN surrounding a multiwalled carbon nanotube (MWCNT) core. Laser-induced damage testing of

Methods for TEM analysis of NIST’s SWCNT SRM

March 25, 2010
Author(s)
Roy H. Geiss, Elisabeth Mansfield, Jeffrey A. Fagan
The National Institute of Standards and Technology (NIST) is developing a series of single-walled carbon nanotube, SWCNT, reference materials, RMs, to provide researchers with well characterized materials for their applications. The SWCNT reference
