  • Radovic-Moreno, Aleksandar F.; Lu, Timothy K.; Puscasu, Vlad A.; Yoon, Christopher J.; Langer, Robert; Farokhzad, Omid C. (American Chemical Society (ACS), 2012-04)
    Bacteria have shown a remarkable ability to overcome drug therapy if there is a failure to achieve sustained bactericidal concentration or if there is a reduction in activity in situ. The latter can be caused by localized ...
  • Tsvetkov, Nikolai; Lu, Qiyang; Chen, Yan; Yildiz, Bilge (Electrochemical Society, 2013-10)
    The influence of lattice strain on non-stoichiometry and surface chemical composition was investigated for epitaxial Nd2NiO4+ä (NNO) films during annealing in ultra high vacuum (below 10[superscript -8] mbar) and temperatures ...
  • Brown, M. E.; Burgasser, Adam J.; Fraser, W. C. (Institute of Physics/American Astronomical Society, 2011-09)
    We present photometry and spectra of the large Kuiper belt object 2007 OR10. The data show significant near-infrared absorption features due to water ice. While most objects in the Kuiper belt with water ice absorption ...
  • Kim, Tony Hyun; Herskind, Peter F.; Chuang, Isaac L. (American Institute of Physics (AIP), 2011-05)
    An atomic ion is trapped at the tip of a single-mode optical fiber in a cryogenic (8 K) surface-electrode ion trap. The fiber serves as an integrated source of laser light, which drives the quadrupolequbit transition of ...
  • Chuang, Isaac L.; Kim, Tony Hyun; Herskind, Peter F.; Kim, Taehyun; Kim, Jungsang (American Physical Society, 2010-10)
    We present a model as well as experimental results for a surface electrode radiofrequency Paul trap that has a circular electrode geometry well suited for trapping single ions and two-dimensional planar ion crystals. The ...
  • Tran, Richard; Xu, Zihan; Radhakrishnan, Balachandran; Winston, Donald; Persson, Kristin A.; Ong, Shyue Ping; Sun, Wenhao (Nature Publishing Group, 2016-09)
    The surface energy is a fundamental property of the different facets of a crystal that is crucial to the understanding of various phenomena like surface segregation, roughening, catalytic activity, and the crystal’s ...
  • Saha, Krishanu; Mei, Ying; Reisterer, Colin M.; Pyzocha, Neena Kenton; Yang, Jing; Muffat, Julien; Davies, Martyn C.; Alexander, Morgan R.; Langer, Robert; Anderson, Daniel G.; Jaenisch, Rudolf (National Academy of Sciences, 2011-11)
    The current gold standard for the culture of human pluripotent stem cells requires the use of a feeder layer of cells. Here, we develop a spatially defined culture system based on UV/ozone radiation modification of typical ...
  • Xu, Weigao; Ling, Xi; Xiao, Jiaqi; Dresselhaus, Mildred; Kong, Jing; Hu, Hongxing; Liu, Zhongfan; Zhang, Jin (National Academy of Sciences (U.S.), 2012-06)
    Surface enhanced Raman spectroscopy (SERS) is an attractive analytical technique, which enables single-molecule sensitive detection and provides its special chemical fingerprints. During the past decades, researchers have ...
  • Schildgen, T. F.; Cosentino, D.; Caruso, A.; Buchwaldt, Robert; Yildirim, C.; Bowring, Samuel A.; Rojay, B.; Echtler, H.; Strecker, M. R. (American Geophysical Union (AGU), 2012-03)
    he southwest margin of the Central Anatolian Plateau has experienced multiple phases of topographic growth, including the formation of localized highs prior to the Late Miocene that were later affected by wholesale uplift ...
  • Jadidian, Jouya; Zahn, Markus; Lavesson, Nils; Widlund, Ola; Borg, Karl (American Institute of Physics (AIP), 2012-04)
    Flashover formation and expansion mechanisms on the surfaces of different dielectrics immersed in transformer oil have been numerically analyzed. Streamers emanating from a needle electrode tend to transform to surface ...
  • Bateni, S. M.; Entekhabi, Dara (American Geophysical Union (Wiley platform), 2012-08)
    [1] The estimation of surface heat fluxes based on the assimilation of land surface temperature (LST) has been achieved within a variational data assimilation (VDA) framework. Variational approaches require the development ...
  • Shah, Nisarg J.; Hyder, Md Nasim; Moskowitz, Joshua Seth; Quadir, Mohiuddin Abdul; Morton, Stephen Winford; Seeherman, Howard J.; Padera, Robert F.; Spector, Myron; Hammond, Paula T. (American Association for the Advancement of Science (AAAS), 2013-06)
    The functional success of a biomedical implant critically depends on its stable bonding with the host tissue. Aseptic implant loosening accounts for more than half of all joint replacement failures. Various materials, ...
  • Gargallo-Peiró, Abel; Sarrate, Josep; Roca Navarro, Francisco Javier (Springer Berlin Heidelberg, 2013-09)
    A method to optimize triangular and quadrilateral meshes on parameterized surfaces is proposed. The optimization procedure relocates the nodes on the surface to improve the quality (smooth) and ensures that the elements ...
  • Tan, Aaron; Farhatnia, Yasmin; Goh, Debbie; G, Natasha; de Mel, Achala; Lim, Jing; Teoh, Swee-Hin; Malkovskiy, Andrey V; Chawla, Reema; Rajadas, Jayakumar; Cousins, Brian G; Alavijeh, Mohammad S; Seifalian, Alexander M; Hamblin, Michael R. (Springer-Verlag, 2013-08)
    An unmet need exists for the development of next-generation multifunctional nanocomposite materials for biomedical applications, particularly in the field of cardiovascular regenerative biology. Herein, we describe the ...
  • Kim, Jun Young; Lim, Dae Young (MDPI Publishing, 2010-04)
    This paper describes the fabrication of novel modified polyethylene (PE) membranes using plasma technology to create high-performance and cost-effective separator membranes for practical applications in lithium-ion polymer ...
  • Massobrio, C.; Bouzid, A.; Boero, M.; Ori, Guido; Coasne, Benoit Alain (American Physical Society, 2014-07)
    First-principles calculations within the framework of the density functional theory are used to construct realistic models for the surface of glassy GeS[subscript 2](g−GeS[subscript 2]). Both calculations at T = 0 K and ...
  • Ram, Rajeev J.; Montoya, J.; Hensley, J.; Parameswaran, K.; Allen, M. (Institute of Electrical and Electronics Engineers, 2009-08)
    Here we present an integrated isolator design based on nonreciprocal coupling into a magnetooptic surface-plasmon waveguide that achieves an isolation >30 dB with an insertion <3 dB in a device length <100 mum.
  • Covey, Curt; Dai, Aiguo; Marsh, Daniel R.; Lindzen, Richard Siegmund (American Meteorological Society, 2011-03)
    Although atmospheric tides driven by solar heating are readily detectable at the earth’s surface as variations in air pressure, their simulations in current coupled global climate models have not been fully examined. This ...
