  • Effect of substrate geometry on liquid-crystal-mediated nanocylinder-substrate interactions 

    Cheung, David L.; Allen, Michael P. (American Institute of Physics, 2008)
    Using classical density functional theory, the liquid crystal (LC)-mediated interaction between a cylindrical nanoparticle and a structured substrate is studied. The surface is structured by cutting a rectangular groove ...
  • Influence of chemical composition on the fluorescence lifetimes of crude petroleum oils 

    Ryder, Alan G.; Glynn, Thomas J.; Feely, Martin (Society of Photo-optical Instrumentation Engineers, 2003)
    Fluorescence based methods are increasingly being used for the analysis of crude oils because they offer high speed, low cost, non-contact, and non-destructive testing options. The fluorescence of crude oils is due to the ...
  • Investigation of nanoscale structural alterations of cell nucleus as an early sign of cancer 

    Alexandrov, Sergey (BioMed Central, 2014)
    Background: The cell and tissue structural properties assessed with a conventional bright-field light microscope play a key role in cancer diagnosis, but they sometimes have limited accuracy in detecting early-stage cancers ...
  • Monte Carlo simulations of liquid crystals between microstructured substrates 

    Cheung, David L. (American Institute of Physics, 2008)
    The structure of a model liquid crystalline fluid confined between two microstructured substrates is studied through Monte Carlo simulations. A simple model for a structured substrate, similar in spirit to those used for ...
  • Nano-sensitive optical coherence tomography 

    Alexandrov, Sergey; Subhash, Hrebesh M.; Zam, Azhar; Leahy, Martin (Royal Society of Chemistry, 2014)
    Depth resolved label-free detection of structural changes with nanoscale sensitivity is an outstanding problem in the biological and physical sciences and has significant applications in both the fundamental research and ...
  • Novel approach for label free super-resolution imaging in far field 

    Alexandrov, Sergey; McGrath, James; Hrebesh, Subhash; Leahy, Martin (Nature Publishing Group, 2015)
    Progress in the emerging areas of science and technology, such as bio- and nano-technologies, depends on development of corresponding techniques for imaging and probing the structures with high resolution. Recently, the ...
  • Search for Pulsed TeV Gamma-ray Emission from the Crab Pulsar 

    Lang, Mark; Gillanders, Gary; Lessard, R. W.; Bond, I. H.; Bradbury, S. M.; Buckley, J. H.; Burdett, A. M.; Carter-Lewis, D. A.; Catanese, M.; Cawley, M. F.; D'Vali, M.; Fegan, D. J.; Finley, J. P.; Gaidos, J. A.; Gillanders, G. H.; Hall, T.; Hillas, A. M.; Krennrich, F.; Lang, M. J.; Masterson, C.; Moriarty, P.; Quinn, J.; Rose, H. J.; Samuelson, F. W.; Sembroski, G. H.; Srinivasan, R.; Vassiliev, V. V.; Weekes, T. C. (1999)
    We present the results of a search for pulsed TeV emission from the Crab pulsar using the Whipple Observatory's 10 m gamma-ray telescope. The direction of the Crab pulsar was observed for a total of 73.4 hours between 1994 ...
