Refrigerant Properties for Heat Transfer Analysis

January 27, 2013
Author(s)
Mark O. McLinden
Presentation at 2013 Winter Annual Meeting of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), Dallas, Texas, January 27, 2013. The importance of fluid properties for heat transfer analysis in refrigeration

Possibilities, Limits, and Tradeoffs for Refrigerants in the Vapor Compression Cycle

October 29, 2012
Author(s)
Mark O. McLinden, Andrei F. Kazakov, J S. Brown, Piotr A. Domanski, Jae H. Heo
We explore the possibilities for refrigerants having low global warming potential (GWP) using two distinct, but complimentary, approaches. In the first approach, we evaluate the effect of a refrigerant’s fundamental thermodynamic parameters on its

SCIENCE-BASED METRICS FOR PRODUCT SUSTAINABILITY ASSESSMENT

September 30, 2012
Author(s)
Barbara C. Lippiatt
Consumers and manufacturers need compelling metrics, tools, and data supporting investments in sustainable products. Today’s marketplace is fraught with sustainability claims that are often based on incomplete, anecdotal evidence that is difficult to

Characterization of Surface Accumulation and Release of Nanosilica During Irradiation of Polymer Nanocomposites with Ultraviolet Light

August 12, 2012
Author(s)
Tinh Nguyen, Bastien T. Pellegrin, Coralie Bernard, Savelas A. Rabb, Paul E. Stutzman, Justin M. Gorham, Xiaohong Gu, Lee L. Yu, Joannie W. Chin
Nanofillers are increasingly used for enhancing multiple properties of polymeric materials in many applications. However, polymers are susceptible to photodegradation by solar ultraviolet (UV) radiation Therefore, nanofillers in a polymer nanocomposite

SEABIRD TISSUE ARCHIVAL AND MONITORING PROJECT: Egg Collections and Analytical Results for 2006-2009

August 2, 2012
Author(s)
Stacy S. Schuur, Paul R. Becker, Sylvain Berail, Russell D. Day, Olivier F. Donard, Keith A. Hobson, Amanda J. Moors, Rebecca S. Pugh, Lauren B. Rust, David G. Roseneau
Since 1999, the Seabird Tissue Archival and Monitoring Project (STAMP) has collected, banked, and analyzed seabird eggs using established protocols to monitor chlorinated pesticides, polychlorinated biphenyls (PCBs), brominated flame retardants, and

The winter time South Pole tropospheric water vapor column: Comparisons of radiosonde and recent terahertz radiometry, use of the saturated column as a proxy measurement; and inference of decadal trends

July 7, 2012
Author(s)
Richard A. Chamberlin, Erich N. Grossman
We use a fifty year record of winter time radiosonde observations at the South Pole to estimate the precipitable water vapor column (PWV) over the entire period. Humidity data from older radiosondes is of limited reliability; however, we think an

Anisotropic Field Evaporation of Diatomic Species from Oxides and Nitrides

May 21, 2012
Author(s)
Matthew D. Brubaker, David R. Diercks, R Kirchofer, Kristine A. Bertness, Norman A. Sanford, Brian Gorman
Recent work using laser-assisted atom probe tomography on non-metallic materials has indicated that for many data collection conditions, anisotropic evaporation can occur. In some cases this can be attributed to a high laser energy leading to uneven

Environmental Metabolomics

March 15, 2012
Author(s)
Daniel W. Bearden
The application of metabolomics in the field of environmental science or ecology, which has developed based substantially on NMR spectroscopic approaches, is a fast paced, rapidly developing field which seems to be poised to help re-frame the discussion of

Spatial distribution of bottlenose dolphins (Tursiops truncatus) inferred from stable isotopes and priority organic pollutants

February 15, 2012
Author(s)
Rachel Wilson, John Kucklick, Brian C. Balmer, Randall Wells, Jeffery Chanton, Doug Nowacek
Differences in priority organic pollutants (POPs), analyzed by gas chromatography-mass spectrometry, and stable isotope ratios (δ¹³C, δ³⁴S, and δ¹⁵N; analyzed by isotope ratio-mass spectrometry), divide 77 bottle- nose dolphins (Tursiops truncatus) from

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
