Template synthesis of gold nanoparticles with an organic molecular cage

January 16, 2014
Author(s)
Ryan McCaffrey, Hai Long, Yinghua Jin, Aric Sanders, Wounjhang Park, Wei Zhang
We report a novel strategy for the controlled synthesis of gold nanoparticles (AuNPs) with narrow size distribution (1.9 plus or minus} 0.4 nm) through NP nucleation and growth inside the cavity of a well-defined three-dimensional, shape-persistent organic

Probing the intracellular glutathione redox potential using in-cell NMR spectroscopy

January 2, 2014
Author(s)
Steve Y. Rhieu, Aaron A. Urbas, Daniel W. Bearden, John P. Marino, Vytautas Reipa, Katrice A. Lippa
Non-invasive and real-time analysis of cellular redox processes has been greatly hampered by lack of suitable measurement techniques. Here we describe an in-cell nuclear magnetic resonance (NMR)-based method for measuring the intracellular glutathione

Correlation of rocket propulsion fuel properties with chemical composition using comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry followed by partial least squares regression analysis

December 30, 2013
Author(s)
Thomas J. Bruno, Benjamin Kehimkar, Jamin C. Hoggard, Luke C. Marney, M. C. Billingsley, C. G. Fraga, R. E. Synovec
There is an increased need to more fully assess and control the composition of kerosene-based rocket propulsion fuels such as RP-1. In particular, it is critical to make better quantitative connections among the following three attributes: fuel performance

Inhibition of DNA glycosylases via small molecule purine analogs

December 9, 2013
Author(s)
M Miral Dizdar, Aaron C. Jacobs, Ajit Jadhav, Dorjbal Dorjsuren, David Maloney, Anton Simeonov, Pawel Jaruga, Amanda K. McCullough, R. S. Lloyd
Following the formation of oxidatively-induced DNA damage, several DNA glycosylases are required to initiate repair of the base lesions that are formed. Recently, NEIL1 and other DNA glycosylases, including OGG1 and NTH1 were identified as potential

High-Accuracy Measurements of the Vapor Pressure of Ice Referenced to the Triple Point

December 6, 2013
Author(s)
Katarzyna E. Bielska, Daniel K. Havey, Gregory E. Scace, D Lisak, Allan H. Harvey, Joseph T. Hodges
The vapor pressure of hexagonal (Ih) ice was measured over the temperature range 175 K to 253.4 K and referenced to the value at the triple point of water. This experiment combined a highly accurate humidity generation system containing an ice-coated

Fluctuation Enhanced Sensing (FES) with a Nanostructured Semiconducting Metal Oxide Film for Gas Detection and Classification

October 31, 2013
Author(s)
Bulent Ayhan, Chiman Kwan, Jin Zhou, Laszlo Kish, Kurt D. Benkstein, Phillip H. Rogers, Stephen Semancik
The feasibility of fluctuation-enhanced sensing (FES) for the detection and classification of different gases by using a single microsensor has been experimentally demonstrated. A nanostructured semiconducting metal oxide film has been used as a

Connection between thermodynamics and dynamics of simple fluids in highly attractive pores

October 25, 2013
Author(s)
William P. Krekelberg, Vincent K. Shen, Daniel W. Siderius, Thomas M. Truskett, Jeffrey R. Errington
We investigate the structural and diffusive dynamics properties of a model fluid in highly-absorptive cylindrical pores. At subcritical temperatures, self diffusion displays three distinct regimes as a function of average pore density ρ: 1) a decrease in

Spectral line shapes investigation with Pound-Drever-Hall-locked frequency-stabilized cavity ring-down spectroscopy

October 23, 2013
Author(s)
A. Cygan, S. Wojtewicz, J. Domyslawska, Piotr Maslowski, Katarzyna E. Bielska, M. Piwinski, K. Stec, R.S. Trawinski, F Ozimek, C. Radzewicz, Hisashi Abe, T. Ido, Joseph T. Hodges, D Lisak, R. Ciurylo
A review of recent experiments involving a newly developed Pound-Drever-Hall-locked frequency-stabilized cavity ring-down spectroscopy (PDH-locked FS-CRDS) system is presented. By comparison to standard FS-CRDS, the PDH lock of the probe laser to the ring

The Seventh Industrial Fluid Properties Simulation Challenge

October 8, 2013
Author(s)
Riaz Ahmad, John K. Brennan, Kevin A. Frankel, Jonathan D. Moore, Joshua D. Moore, Raymond D. Mountain, Richard B. Ross, Vincent K. Shen, Nathan E. Schultz, Daniel Siderius, Kenneth D. Smith, Matthias Thommes
The primary goal of the seventy industrial fluid properties simulation challenge was to test the ability of molecular simulation methods to predict the adsorption of organic adsorbates in zeolite materials. Zeoliet adsorbents are used in a variety of
