MECHANICS ANALYSIS OF MOLAR TOOTH SPLITTING

December 12, 2014
Author(s)
Amir Barani, Brian R. Lawn, Mark Bush, Herzl Chai
A model for the splitting of teeth from wedge loading of molar cusps from a round indenting object is presented. The model is developed in two parts: first, a simple 2D fracture mechanics configuration with the wedged tooth simulated by a compact tension

Analysis of One-Minute Potentially Available Fluoride from Dentifrice

December 4, 2014
Author(s)
Clifton Carey, Erin Holahan
Previous reports found that some fluoride containing dentifrices do not release effective concentrations of fluoride during brushing. Failure to release fluoride can be due to dentifrice matrix components that interfere with the solubilization of the

Analytical Ultracentrifugation of Carbon Nanotubes

November 26, 2014
Author(s)
Jeffrey A. Fagan
Sedimentation velocity (SV) experiments on dispersed nanoparticles are a powerful method for determining otherwise hard to evaluate properties of the nanoparticle such as the density and size of the adsorbed interfacial layer, or for a direct evaluation of

High-Relaxivity Superparamagnetic Iron Oxide Nanoworms with Decreased Immune Recognition and Long-Circulating Properties

November 24, 2014
Author(s)
Stephen E. Russek, Guankui Wang, Swetha Inturi, Natalie J. Serkova, Sergey Merkulov, Keith McCrae, Nirmal K. Banda, Dmitri Simberg
One of the core issues of nanotechnology involves masking the foreignness of nanomaterials to enable in vivo longevity and long-term immune evasion. Dextran-coated superparamagnetic iron oxide nanoparticles are very effective magnetic resonance imaging

NIST Micronutrients Measurement Quality Assurance Program Summer 2013 Comparability Studies: Results for Round Robin LXXIV Fat-Soluble Vitamins and Carotenoids in Human Serum and Round Robin 39 Ascorbic Acid in Human Serum

October 30, 2014
Author(s)
Jeanice M. Brown Thomas, David L. Duewer
The National Institute of Standards and Technology coordinates the Micronutrients Measurement Quality Assurance Program (MMQAP) for laboratories that measure fat- and water-soluble vitamins and carotenoids in human serum and plasma. This report describes

NIST Micronutrients Measurement Quality Assurance Program Winter 2013 Comparability Studies: Results for Round Robin LXXIII Fat-Soluble Vitamins and Carotenoids in Human Serum and Round Robin 38 Ascorbic Acid in Human Serum

October 30, 2014
Author(s)
Jeanice M. Brown Thomas, David L. Duewer

A Microliter Capillary Rheometer for Characterization of Protein Solutions

October 10, 2014
Author(s)
Steven D Hudson, Prasad S. Sarangapani, Kalman D. Migler, Jai A. Pathak
Rheometry is an important characterization tool for therapeutic protein solutions because it determines syringeability and relates indirectly to solution stability and thermodynamic interactions. Despite the maturity of rheometry, there remains a need for

In-situ morphology studies of the mechanism for solution additive effects on the formation of bulk heterojunction films.

September 29, 2014
Author(s)
Lee J. Richter, Dean M. DeLongchamp, Kang W. Chou, Aram Amassian, A Hexemer, Eric Schaible, Felicia A. Bokel, Sebastian Engmann
The most successful active film morphology in organic photovoltaics is the bulk heterojunction (BHJ). The performance of a BHJ arises from a complex interplay of the spatial organization of the segregated donor and acceptor phases and the local order

TESTING AND ANALYSES OF COPOLYMER FIBERS BASED ON 5-AMINO-2-(P-AMINOPHENYL)-BENZIMIDAZOLE

September 22, 2014
Author(s)
Walter G. McDonough, Joy P. Dunkers, Amanda L. Forster, Jae Hyun Kim, Scott A. Wight, Gale A. Holmes
Since the well-publicized failure of a body armor used by a police officer at a threat level the armor had been designed to survive, it has become imperative that the long-term properties and performance of new fibers being considered for use be understood
