    • Direct Measurements of Island Growth and Step-Edge Barriers in Colloidal Epitaxy 

      Ganapathy, R.; Buckley, M.R.; Gerbode, S.J.; Cohen, I. (AMER ASSOC ADVANCEMENT SCIENCE, 1200 NEW YORK AVE, NW, WASHINGTON, DC 20005 USA, 2010-01-22)
      Epitaxial growth, a bottom-up self-assembly process for creating surface nano-and microstructures, has been extensively studied in the context of atoms. This process, however, is also a promising route to self-assembly of ...
    • High Resolution Shear Profile Measurements in Entangled Polymers 

      Hayes, K.A.; Buckley, M.R.; Cohen, I.; Archer, L.A. (Physical Review Letters, 2008-11-17)
      We use confocal microscopy and particle image velocimetry to visualize motion of 250-300 nm. fluorescent tracer particles in entangled polymers subject to a rectilinear shear flow. Our results show linear velocity profiles ...
    • The synthesis and properties of nanoscale ionic materials 

      Rodriguez, R.; Herrera, R.; Bourlinos, A.; Li, R.; Amassian, A.; Archer, L.A.; Giannelis, E.P. (John Wiley & Sons, Ltd., 2010-02-17)
      In this article we discuss the effect of constituents on structure, flow, and thermal properties of nanoscale ionic materials (NIMs). NIMs are a new class of nanohybrids consisting of a nanometer-sized core, a charged ...
    • Mesoscopic structure prediction of nanoparticle assembly and coassembly: Theoretical foundation 

      Hur, K.; Hennig, R.G.; Escobedo, F.A.; Wiesner, U.B. (American Institute of Physics, 2010-11-19)
      In this work, we present a theoretical framework that unifies polymer field theory and density functional theory in order to efficiently predict ordered nanostructure formation of systems having considerable complexity in ...
    • An In Situ Method of Creating Metal Oxide-Carbon Composites and Their Application as Anode Material for Lithium-Ion Batteries 

      Yang, Z.; Shen, J.; Archer, L.A. (Royal Society of Chemistry, 2011-06-13)
      Transition metal oxides are actively investigated as anode materials for lithium-ion batteries (LIBs), and their nanocomposites with carbon frequently show better performance in galvanostatic cycling studies, compared to ...
    • Superhydrophilic and solvent resistant coatings on polypropylene fabrics by a simple deposition process 

      Fang, J.; Kelarakis, A.; Estevez, L.; Wang, Y.; Rodriguez, R.; Giannelis, E.P. (ROYAL SOC CHEMISTRY, 2010-02-01)
      A simple, yet general coating method to plasma treated polymeric substrates is presented. The method is based on electrostatic interactions between the surface functionalized nanoparticles and the charged substrate and ...
    • Fouling Release Nanostructured Coatings based on PDMS-polyurea Segmented Copolymers 

      Fang, J.; Kelarakis, A.; Wang, D.; Giannelis, E.P. (ELSEVIER SCI LTD, 2010-05-28)
      The bulk and surface characteristics of a series of coatings based on PDMS-polyurea segmented copolymers were correlated to their fouling release performance. Incorporation of polyurea segments to PDMS backbone gives rise ...
    • Miscibility-Dispersion, Interfacial Strength and Nanoclay Mobility Relationships in Polymer Nanocomposites 

      Carretero-González, J.; Retsos, H.; Giannelis, E.P.; Ezquerra, T.A.; Hernández, M.; López-Manchado, M.A. (ROYAL SOC CHEMISTRY, 2009-07-08)
      Fully dispersed layered silicate nanoparticles (nanoclay) in a polymer matrix have provided a new class of multi-functional materials exhibiting several performance improvements over conventional composites. Yet the ...
    • Transition Path Sampling and Forward Flux Sampling. Applications to Biological Systems. 

      Escobedo, F.A.; Borrero, E.E.; Araque, J.C. (Journal of Physics: Condensed Matter, 2009-07-13)
      The last decade has seen a rapid growth in the number of simulation methods and applications dealing with the sampling of transition pathways of rare nanoscale events. Such studies are crucial, for example, for understanding ...
