    Distributed temperature data are used as input and as calibration data for an energy based temperature model of a first order stream in Luxembourg. A DTS (Distributed Temperature Sensing) system with a fiber optic cab ...
  • Rupp, David E.; Selker, John S. (American Geophysical Union, 2005)
    Solutions to the Boussinesq equation describing drainage into a fully penetrating channel have been used for aquifer characterization. Two analytical solutions exist for early- and late-time drainage from a saturated, ho ...

  • Kim, Ki-Joong; Ahn, Ho-Geun (Elsevier, 2012-04-01)
    Mordenite and X- or Y-type faujasite were used to remove volatile organic compounds (VOCs) by adsorption at 25 °C. A microwave heating desorption system was applied for pollutant adsorbent regeneration. Studies were focu ...
  • Weisbrod, Noam; McGinnis, Thomas; Rockhold, Mark L.; Niemet, Michael R.; Selker, John S. (American Geophysical Union, 2009-10-17)
    Surface tensions of high-salinity solutions are significantly different from those of pure water. Our objective was to develop and test a methodology to determine whether these surface tension effects predictably alter i ...
  • Choi, Chang-Ho; Su, Yu-Wei; Chang, Chih-hung (Royal Society of Chemistry, 2013)
    Assembly of nanocrystals is considered one of the most promising approaches to design nano-, microstructures, and complex mesoscopic architectures. A variety of strategies to induce nanocrystal assembly have been reporte ...
  • Nason, Jeffrey A.; McDowell, Shannon A.; Callahan, Ty W. (Royal Society of Chemistry, 2012-07)
    The aggregation of 12 nm citrate-stabilized gold nanoparticles (cit-AuNPs) in the presence of four different natural organic matter (NOM) isolates and a monovalent electrolyte (KCl) was evaluated using time-resolved dy ...
  • Burns, Erick R.; Selker, John S.; Parlange, Jean-Yves; Guenther, Ronald B. (American Geophysical Union, 2006-05-03)
    Though many arid and contaminated sites have high salinity, prediction of effects of salinity on water movement in soils has been based on dilute solution approximations. Here a sensitivity analysis compares predicted li ...
  • Hendricks, Terry J.; Krishnan, Shankar; Choi, Changho; Chang, Chih-hung; Paul, Brian (Elsevier, 2010-07)
    Enhanced pool boiling critical heat fluxes (CHF) at reduced wall superheat on nanostructured substrates are reported. Nanostructured surfaces were realized using a low temperature process, microreactor-assisted-nanomat ...
  • Tyler, Scott W.; Selker, John S.; Hausner, Mark B.; Hatch, Christine E.; Torgersen, Thomas; Thodal, Carl E.; Schladow, S. Geoffrey (American Geophysical Union, 2009-01-28)
    Raman spectra distributed temperature sensing (DTS) by fiber-optic cables has recently shown considerable promise for the measuring and monitoring of surface and near-surface hydrologic processes such as groundwater–su ...
  • Selker, John S.; Rupp, David E. (American Geophysical Union, 2005)
    Quality concerns drive many water studies and practices, but obtaining samples from water bodies over time and space for quality determination is often difficult and expensive. We present a low-cost approach that allows ...
  • Selker, John S.; Schroth, Martin H. (American Geophysical Union, 1998-08)
    The use of dimensionless scaling is ubiquitous to hydrodynamic analysis, providing a powerful method of extending limited experimetnal results and generalizing theories. Miller and Miller [1956] contributed a scaling fra ...
  • Vercauteren, Nikki; Huwald, Hendrik; Bou-Zeid, Elie; Selker, John S.; Lemmin, Ulrich; Parlange, Marc B.; Lunati, Ivan (American Geophysical Union, 2011-09-27)
    In lentic water bodies, such as lakes, the water temperature near the surface typically increases during the day, and decreases during the night as a consequence of the diurnal radiative forcing (solar and infrared radia ...
  • Selker, J. S.; Fry, V. A.; Gorelick, S. M. (American Geophysical Union, 1997-12)
    Oxygen is often the rate-limiting factor in aerobic in situ bioremediation. This paper investigates the degree to which air or oxygen gas can be emplaced into the pore space of saturated porous media and provide a signif ...
  • Du, Xiaosong; Durgan, Christopher J.; Matthews, David J.; Motley, Joshua R.; Tan, Xuebin; Pholsena, Kovit; Árnadóttir, Líney; Castle, Jessica R.; Jacobs, Peter G.; Cargill, Robert S.; Ward, W. Kenneth; Conley, John F., Jr.; Hermana, Gregory S. (Electrochemical Society, 2015-02-18)
    This study details the use of printing and other additive processes to fabricate a novel amperometric glucose sensor. The sensor was fabricated using a Au coated 12.7 μm thick polyimide substrate as a starting material, ...
  • Nason, Jeffrey A.; Bloomquist, Don J.; Sprick, Matthew S. (American Society of Civil Engineers, 2012-07)
    Highway stormwater runoff represents a significant source of dissolved copper to surface waters. It is well established that even low concentrations of dissolved copper can be toxic to many aquatic organisms. In the Pa ...
  • Steele‐Dunne, S. C.; Rutten, M. M.; Krzeminska, D. M.; Hausner, M.; Tyler, S. W.; Selker, J.; Bogaard, T. A.; van de Giesen, N. C. (American Geophysical Union, 2010-06-05)
    Through its role in the energy and water balances at the land surface, soil moisture is a key state variable in surface hydrology and land-atmosphere interactions. Point observations of soil moisture are easy to make usi ...
