Coverage-Dependent Morphology of PEGylated Lysozyme Layers Adsorbed on Silica

January 4, 2012
Author(s)
Sheetal S. Pai, Frank Heinrich, Adam L. Canady, Todd M. Przybycien, Robert D. Tilton
Neutron reflection was used to characterize the adsorbed layer structure for lysozyme conjugated at the N-terminus with a single perdeuterated methoxy poly(ethylene glycol) chain at the silica/water interface. Adsorbed layers were produced with two

Calibrated nanoscale dopant profiling using a scanning microwave microscope.

January 3, 2012
Author(s)
Pavel Kabos, Thomas M. Wallis, H P. Hubner, I. Humer, M. Hochleitner, M. Fenner, M. Moertelmaier, C. Rankl, Atif A. Imtiaz, H. Tanbakuchi, P. Hinterdorfer, J. Smoliner, Joseph J. Kopanski, F. Kienberger
The scanning microwave microscope (SMM) is used for calibrated capacitance spectroscopy and spatially resolved dopant profiling measurements. It consists of an atomic force microscope (AFM) combined with a vector network analyzer operating between 1-20 GHz

Controlling the Self-Assembly of Metal-Seamed Organic Nanocapsules

January 3, 2012
Author(s)
Harshita Kumari, Andrew V. Mossine, Steven R. Kline, Cindi L. Dennis, Drew A. Fowler, Simon J. Teat, Charles L. Barnes, Carol A. Deakyne, Jerry L. Atwood
Puzzling out the intricacies associated with formation of supramolecular structures provides insight into and control of the self-assembly process. Such control may allow tailoring of these structures for specific applications. Herein we report the results

FIRE PATTERN REPEATABILITY: A STUDY IN UNCERTAINTY

January 3, 2012
Author(s)
Daniel M. Madrzykowski, Charles Fleischmann
The National Institute of Standards and Technology (NIST) is conducting a multi-year study, with the support of the National Institute of Justice (NIJ) and the NIST Office of Law Enforcement Standards (OLES), to examine the repeatability of burn patterns

MICROHOTPLATE TEMPERATURE SENSOR CALIBRATION AND BIST

January 3, 2012
Author(s)
Muhammad Y. Afridi, Christopher B. Montgomery, Stephen Semancik, Kenneth G. Kreider, Jon C. Geist
In this paper we describe a novel long-term microhotplate temperature sensor calibration technique suitable for Built-In Self Test (BIST). The microhotplate thermal resistance (thermal efficiency) and the thermal voltage from an integrated platinum-rhodium

Theoretical optical and x-ray spectra of liquid and solid H2O

January 3, 2012
Author(s)
Eric L. Shirley, Joshua J. Kas, J. T. Vinson, Fernando D. Vila, John J. Rehr
Theoretical optical and x-ray spectra of model structures of water and ice are calculated using a many-body perturbation theory, Bethe-Salpeter equation (BSE) approach implemented in the valence- and core-excitation codes AI2NBSE and OCEAN. These codes use

Fine Limestone Additions to Regulate Setting in High Volume Fly Ash Mixtures

January 2, 2012
Author(s)
Dale P. Bentz, Taijiro Sato, Igor de la Varga, Jason Weiss
High volume fly ash (HVFA) concrete mixtures are being considered more frequently due to their cost and sustainability advantages. While the long term performance of these HVFA concretes typically meets or exceeds that of conventional concretes, their
