Predicting enzyme adsoprtion to lignin films from enzyme surface hydrophobicity

May 29, 2014
Author(s)
Deanne W. Sammond, John M. Yarbrough, Elisabeth Mansfield, Yannick J. Bomble, Sarah Hobdey, Stephen R. Decker, Larry Taylor, Michael G. Resch, Michael E. Himmel, Todd B. Vinzant, Michael F. Crowley
The loss of digestive activity of cellulase cocktails on biomass is a major challenge, commonly attributed to the binding of certain enzymes to lignin. While the binding mechanism remains unclear, hydrophobic interactions between enzymes and lignin are

Three-Dimensional Hydrogel Constructs for Dosing Cells with Nanoparticles

January 13, 2014
Author(s)
Elisabeth Mansfield, Tammy L. Oreskovic, Nikki S. Rentz, Kavita M. Jeerage
In evaluating nanoparticle risks to human health, there is often a disconnect between results obtained from in vitro toxicology studies and in vivo activity, prompting the need for improved methods to rapidly assess the hazards of engineered nanomaterials

Statistical Sampling of Carbon Nanotube Populations by Thermogravimetric Analysis

December 25, 2013
Author(s)
Elisabeth Mansfield, Aparna Kar, Chih-Ming Wang, Ann C. Chiaramonti Debay
Carbon nanotubes are one of the most promising nanomaterials on the market, with applications in electronics devices, sensing, batteries, composites and medical communities. Strict control of the carbon nanotube chemistry and properties is necessary as the

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

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
