Crazing of Nanocomposites with Polymer-Tethered Nanoparticles
Dong Meng, Sanat K. Kumar, Ting Ge +2
The crazing behavior of polymer nanocomposites formed by blending polymer grafted nanoparticles with an entangled polymer melt is studied by molecular dynamics simulations. We focu…
Universal two-step crystallization of DNA-functionalized nanoparticles
Wei Dai, Sanat K. Kumar, Francis W. Starr
We examine the crystallization dynamics of nanoparticles reversibly tethered by DNA hybridization. We show that the crystallization happens readily only in a narrow temperature "sl…
End Grafted Polymer Nanoparticles in a Polymeric Matrix: Effect of Coverage and Curvature
Joshua Kalb, Douglas Dukes, Sanat K. Kumar +2
It has recently been proposed that the miscibility of nanoparticles with a polymer matrix can be controlled by grafting polymer chains to the nanoparticle surface. As a first step…
Structural Signatures of Vitrification in Hard Core Fluids
Sanat K. Kumar, Shekhar Garde, Jack F. Douglas +1
Computer simulations of hard spheres and disks are used to estimate the most probable cavity size, , and a ``rattle'' size, , over which a particle…
Surface Transitions for Confined Associating Mixtures
Michael Kotelyanskii, Sanat K. Kumar
Thin films of binary mixtures that interact through isotropic forces and directionally specific "hydrogen bonding" are considered through Monte Carlo simulations. We show, in good…
