  • Smith, J. David; Meuler, Adam J.; Bralower, Harrison L.; Venkatesan, Rama; Subramanian, Sivakumar; Cohen, Robert E.; McKinley, Gareth H.; Varanasi, Kripa K. (Royal Society of Chemistry, The, 2012-03)
    Clathrate hydrate formation and subsequent plugging of deep-sea oil and gas pipelines represent a significant bottleneck for deep-sea oil and gas operations. Current methods for hydrate mitigation are expensive and energy ...
  • Wang, Zhe; Fratini, Emiliano; Li, Mingda; Le, Peisi; Mamontov, Eugene; Baglioni, Piero; Chen, Sow-Hsin (American Physical Society, 2014-10)
    The characteristic relaxation time τ of protein hydration water exhibits a strong hydration level h dependence. The dynamic crossover is observed when h is higher than the monolayer hydration level h[subscript c] =0.2–0.25 ...
  • Bertrand, Christopher E.; Liu, K.-H.; Mamontov, Eugene; Chen, Sow-Hsin (American Physical Society, 2013-04)
    We have measured the hydration-level dependence of the single-particle dynamics of water confined in the ordered mesoporous silica MCM-41. The dynamic crossover observed at full hydration is absent at monolayer hydration. ...
  • Khaykin, S.; Pommereau, J.-P.; Korshunov, L.; Yushkov, V.; Nielsen, J.; Larsen, N.; Christensen, T.; Garnier, A.; Lukyanov, A.; Williams, Earle R. (European Geosciences Union, 2009-03)
    The possible impact of deep convective overshooting over land has been explored by six simultaneous soundings of water vapour, particles and ozone in the lower stratosphere next to Mesoscale Convective Systems (MCSs) during ...
  • Labousse, M.; Bush, John W. M. (American Institute of Physics (AIP), 2013-09)
    When a falling jet of fluid strikes a horizontal fluid layer, a hydraulic jump arises downstream of the point of impact, provided a critical flow rate is exceeded. We here examine a phenomenon that arises below this jump ...
  • Lee, Sangyeop; Broido, David; Esfarjani, Keivan; Chen, Gang (Nature Publishing Group, 2015-02)
    Recent studies of thermal transport in nanomaterials have demonstrated the breakdown of Fourier’s law through observations of ballistic transport. Despite its unique features, another instance of the breakdown of Fourier’s ...
  • Bouffanais, Roland; Yue, Dick K. P. (American Physical Society, 2010-04)
    Mechanotactic cell motility has recently been shown to be a key player in the initial aggregation of crawling cells such as leukocytes and amoebae. The effects of mechanotactic signaling in the early aggregation of amoeboid ...
  • Nepf, Heidi (Taylor & Francis/International Association for Hydro-Environment Engineering and Research, 2012-06)
    This paper highlights some recent trends in vegetation hydrodynamics, focusing on conditions within channels and spanning spatial scales from individual blades, to canopies or vegetation patches, to the channel reach. At ...
  • Bush, John W. M.; Hu, David L. (Cambridge University Press, 2010-02)
    We present the results of a combined experimental and theoretical investigation of the dynamics of water-walking insects and spiders. Using high-speed videography, we describe their numerous gaits, some analogous to those ...
  • Helgeson, Matthew E.; Chapin, Stephen C.; Doyle, Patrick S. (Elsevier, 2011-01)
    In recent years, there has been a surge in methods to synthesize geometrically and chemically complex microparticles. Analogous to atoms, the concept of a “periodic table” of particles has emerged and continues to be ...
  • Camci-Unal, Gulden; Nichol, Jason W.; Bae, Hojae; Tekin, Halil; Bischoff, Joyce; Khademhosseini, Ali (John Wiley & Sons, Inc, 2013-05)
    Endothelialization of artificial vascular grafts is a challenging process in cardiovascular tissue engineering. Functionalized biomaterials could be promising candidates to promote endothelialization in repair of cardiovascular ...
  • Nicodemus, Rebecca A.; Ramasesha, Krupa; Roberts, Sean Thomas; Tokmakoff, Andrei (American Chemical Society, 2010-03)
    We use temperature-dependent two-dimensional infrared spectroscopy (2D IR) of dilute HOD in H2O to investigate hydrogen bond rearrangements in water. The OD stretching frequency is sensitive to its environment, and loss ...
  • Kleinke, Andrew S.; Jamison, Timothy F. (American Chemical Society (ACS), 2013-01)
    The first continuous hydrogenation that requires neither H[subscript 2] nor metal catalysis generates diimide by a novel reagent combination. The simple flow reactor employed minimizes residence time by enabling safe ...
  • Sheng, Wenchao; Gasteiger, Hubert A.; Shao-Horn, Yang (The Electrochemical Society, 2010-09)
    The kinetics of the hydrogen oxidation reaction (HOR) and hydrogen evolution reaction (HER) on polycrystalline platinum [Pt(pc)] and high surface area carbon-supported platinum nanoparticles (Pt/C) were studied in 0.1 M ...
  • Sartoretto, Juliano; Kalwa, Hermann; Pluth, Michael D.; Lippard, Stephen J. (National Academy of Sciences, 2011-09)
    Nitric oxide (NO) and hydrogen peroxide (H(subscript 2)O(subscript 2)) are synthesized within cardiac myocytes and play key roles in modulating cardiovascular signaling. Cardiac myocytes contain both the endothelial (eNOS) ...
  • Ding, Hepeng; Demkowicz, Michael J. (Nature Publishing Group, 2015-08)
    Amorphous silicon oxycarbide (SiOC) is of great technological interest. However, its atomic-level structure is not well understood. Using density functional theory calculations, we show that the clustering tendency of C ...
  • Yip, Sidney; Lau, Timothy T.; Van Vliet, Krystyn J.; Monasterio, Paul Rene (American Physical Society, 2009-08)
    Energetics and concentrations of hydrogen-containing point defect clusters (PDCs) in Fe-C alloys are calculated and cast into a PDC dominance diagram. Because of the strong binding effects of iron vacancies on the stability ...
  • Fenty, Ian; Heimbach, Patrick (American Meteorological Society, 2013-05)
    This study investigates the hydrographic processes involved in setting the maximum wintertime sea ice (SI) extent in the Labrador Sea and Baffin Bay. The analysis is based on an ocean and sea ice state estimate covering ...
  • Demory, Marie-Estelle; Eltahir, Elfatih A. B.; Siam, Mohamed Salah (American Meteorological Society, 2013-11)
    The simulations and predictions of the hydrological cycle by general circulation models (GCMs) are characterized by a significant degree of uncertainty. This uncertainty is reflected in the range of Intergovernmental Panel ...
  • Flores, Alejandro N.; Bras, Rafael L.; Entekhabi, Dara (American Geophysical Union, 2012-08)
    [1] Soil moisture information is critical for applications like landslide susceptibility analysis and military trafficability assessment. Existing technologies cannot observe soil moisture at spatial scales of hillslopes ...
