How nanorough is rough enough?

June 21, 2012
Author(s)
Konrad Rykaczewski, William A. Osborn, Jeff Chinn, Marlon L. Walker, John H. Scott, Wanda Jones, Chonglei Hao, Shuhuai Yao, Zuankai Wang
Surfaces which evince superhydrophobic properties during water condensation have a potential to dramatically enhance energy efficiency in power generation and desalination systems. Although various such surfaces have been reported, their development has

Saturation molalities and standard molar enthalpies of solution of alpha-D-xylose(cr) in H2O(l); Standard molar enthalpies of solution of 1,4-beta-D-xylobiose(am), and 1,4-beta-D-xylotriose(am) in H2O(l)

May 14, 2012

Robert N. Goldberg, Brian E. Lang, Bruce Coxon, Stephen R. Decker
The saturation molality of alpha-D-xylose(cr) in water was measured by using HPLC and is m(sat) = (8.43 ± 0.42) mol∙kg-1 at the temperature T = 298.15 K. It was also established that the anhydrous form of alpha-D-xylose(cr) is the crystalline form that is

A Proteomics Performance Standard to Support Measurement Quality in Proteomics

April 21, 2012
Author(s)
Ashley B. Green, David M. Bunk, Paul A. Rudnick, Karen W. Phinney, Lisa E. Kilpatrick
The emergence of mass spectrometry-based proteomic platforms as a prominent technology utilized in biochemical and biomedical research has increased the need for high-quality MS measurements. To address this need, NIST Reference Material (RM) 8323 Yeast

Carbohydrate-Functionalized Surfactant Vesicles for Controlling Glycan Density

March 15, 2012
Author(s)
Monique A. Makos, Rebecca A. Zangmeister
We report on the development of a method for rapidly characterizing the glycan binding properties of lectins. Catanionic surfactant vesicles were prepared that spontaneously formed in water and remained stable at room temperature for months. By varying the

CODATA Recommended Values of the Fundamental Physical Constants: 2010

March 1, 2012
Author(s)
Peter J. Mohr, Barry N. Taylor, David B. Newell
This paper give the 2010 self-consistent set of values of the basic constants and conversion factors of physics and chemistry recommended by the Committee on Data for Science and Technology (CODATA) for international use. The 2010 adjustment takes into

Fitting EXAFS data using molecular dynamics outputs and a histogram approach

February 29, 2012
Author(s)
Bruce D. Ravel, Stephen W. Price, Nicholas Zonias, Chris-Kriton Skylaris, Andrea Russell
It has been shown that for highly disordered systems, EXAFS underestimates coordination number and thus particle size when compared with the theoretical coordination number based on size determination from other experimental techniques1-4. Similarly, when

Measurements and Modeling Study on a High-Aromatic Diesel Fuel

January 31, 2012
Author(s)
Bret Windom, Marcia L. Huber, Thomas J. Bruno, A L. Lown, C T. Lira
The increasing cost of diesel fuel, potential for supply disruptions, and environmental concerns have resulted in a great deal of research to improve the performance and efficiency of diesel engines. This includes significant efforts in the reformulation

First high-resolution analysis of the nu15, nu12, nu5, nu10 and nu2 bands of oxirane

January 15, 2012
Author(s)
Walter J. Lafferty, Jean-Marie Flaud, F. Kwabia Tchana, A. Perrin
Fourier transform spectra of Oxirane (ethylene oxide, c-C2H4O) have been recorded in the 730 cm-1 to 1560 cm-1 (6.4 to 13.7 µm) spectral region using a Bruker IFS125HR spectrometer at a resolution of 0.0019 cm-1. A total of six vibration bands, ν15, ν12

2-Bromo-3,3,3-Trifluoropropene: OH Reaction Rate Constant, IR Absorption Spectrum, Ozone Depletion Potentials and Global Warming Potentials

December 30, 2011
Author(s)
Kenneth O. Patten, Victor Khamaganov, Vladimir L. Orkin, Steven L. Baughcum, Donald J. Wuebbles
The rate constant for the gas phase reaction of OH radicals with BTP (2-Bromo-3,3,3-trifluoropropene, CH2=CBrCF3) was measured using a flash photolysis resonance-fluorescence technique over the temperature range 220 K to 370 K. The Arrhenius plot was found
