  • Geistlinger, Helmut; Mohammadian, Sadjad; Schlüter, Steffen; Vogel, Hans-Joerg (American Geophysical Union, 2014-05-30)
    A major difficulty in modeling multiphase flow in porous media is the emergence of trapped phases. Our experiments demonstrate that gas can be trapped in either single-pores, multipores, or in large connected networks. ...
  • Pommerenck, Justin; Alanazi, Yousef; Gzik, Troy; Vachkov, Richard; Pommerenck, Jordan; Hackleman, David E. (Elsevier, 2012-03)
    Effective heat transfer coefficients and mass transfer rates were determined at varying compositions of steam with 1.5% by weight volatile oils entrained in an air flow. The mixture of volatile oils is comprised of 50% m ...
  • Niemet, Michael R.; Rockhold, Mark L.; Weisbrod, Noam; Selker, John S. (American Geophysical Union, 2002)
    Liquid saturation and gas-liquid interfacial area are important parameters for evaluating the transport and fate of contaminants in unsaturated subsurface environments. Recent findings indicate that interfacial surface a ...
  • Stewart, Ryan D.; Hut, Rolf; Rupp, David E.; Gupta, Hoshin; Selker, John S. (American Geophysical Union, 2012-08-14)
    We propose a novel, accurate quantification of precipitation and evaporation, as needed to understand fundamental hydrologic processes. Our system uses a collection vessel placed on top of a slender rod that is securely ...
  • Du, Xiaosong; Flynn, Brendan T.; Motley, Joshua R.; Stickle, William F.; Bluhm, Hendrik; Herman, Gregory S. (Electrochemical Society, 2014-07-30)
    Self-assembled monolayers (SAMs) have been used to improve both the positive and negative bias-stress stability of amorphous indium gallium zinc oxide (IGZO) bottom gate thin film transistors (TFTs). N-hexylphosphonic a ...
  • Assouline, S.; Selker, J. S.; Parlange, J.-Y. (American Geophysical Union., 2007-03-16)
    The prediction of the time to ponding following commencement of rainfall is fundamental to hydrologic prediction of flood, erosion, and infiltration. Most of the studies to date have focused on prediction of ponding resu ...
  • Tyler, Scott W.; Burak, Susan A.; McNamara, James P.; Lamontagne, Aurele; Selker, John S.; Dozier, Jeff (International Glaciological Society, 2008-12)
    Snowpack base temperatures vary during accumulation and diurnally. Their measurement provides insight into physical, biological and chemical processes occurring at the snow/soil interface. Recent advances in Raman-spec ...
  • Kim, Ki-Joong; Ahn, Ho-Geun (Elsevier, 2012-03-25)
    In this work, stainless steel wire cloth (SSWC) for metallic support was thermally treated to increase the adhesive strength of Al₂O₃ by improving superficial roughness. After coating Al₂O₃ on SSWC, Pt particles as a cat ...
  • Brandi-Dohrn, Florian M.; Dick, Richard P.; Hess, Mario; Selker, John S. (American Geophysical Union, 1996-05)
    An accurate assessment of leaching losses in the vadose zone requires measurement of both solute and water flux to compute flux concentrations (C[subscript F]). Leachate collected at a depth of 1.2 m in 32 passive capill ...
  • Robinson, David; Selker, John; Bowden, Breck; Duncan, John; Durant, John; Hooper, Rick; Jacobs, Jennifer; Knight, Rosemary (American Geophysical Union, 2006-06-06)
    The Consortium of Universities for the Advancement of Hydrologic Sciences, Inc. (CUAHSI) began the Hydrologic Measurement Facility (HMF) program in June 2005 to advance hydrologic measurement capability within the resear ...
  • Selker, J. S.; Suter, J. D.; Cuenca, R. H.; Flugstad, B. A.; Kelly, S. F. (American Geophysical Union, 2009)
    Measurement of soil hydraulic retention and conduction parameters using tension infiltrometers has been found to be useful but has suffered from unreliable instrument membranes at the soil interface and the need for manu ...
  • Rupp, David E.; Keim, Richard F.; Ossiander, Mina; Brugnach, Marcela; Selker, John S. (American Geophysical Union, 2009-07-10)
    Multiplicative random cascades (MRCs) can parsimoniously generate highly intermittent patterns similar to those in rainfall. The elemental MRC model parameter is the cascade weight, which determines how rainfall at one s ...
  • Davidson, Allyson Fry; Glasscock, Cameron; McClanahan, Danielle R.; Benson, James D.; Higgins, Adam Z. (Public Library of Science, 2015-11-25)
    Ice-free cryopreservation, known as vitrification, is an appealing approach for banking of adherent cells and tissues because it prevents dissociation and morphological damage that may result from ice crystal formation. ...
  • Joekar-Niasar, V.; Doster, F.; Armstrong, R. T.; Wildenschild, D.; Celia, M. A. (American Geophysical Union, 2013-07-29)
    Abstract: Several models for two-phase flow in porous media identify trapping and connectivity of fluids as an important contribution to macroscale hysteresis. This is especially true for hysteresis in relative permeabil ...
  • Friesen, J.; van Beek, C.; Selker, J.; Savenije, H. H. G.; van de Giesen, N. (American Geophysical Union, 2008-12-13)
    A method for measuring whole-tree interception of precipitation is presented which employs mechanical displacement sensors to measure trunk compression caused by the water captured by the tree. This direct and nondestruc ...
  • Selker, John (American Institute of Physics, 2010-06)
  • Kreider, Peter B.; Kim, Ki-Joong; Chang, Chih-Hung (Royal Society of Chemistry, 2014-03-05)
    A novel method of copper indium diselenide nanoparticle (CuInSe₂ NP) synthesis using a two-step, continuous flow, solar microreactor is reported here. This method allows for exceedingly fast heating and short reaction ...
