Predicting the linear viscoelastic properties of monodisperse and polydisperse polystyrenes and polyethylenes
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2001-11)
For linear homopolymers the linear viscoelastic predictions of the double reptation model are compared to those of a recent, more detailed model, the “dual constraint model” and to experimental data for monodisperse, ...
High-resolution nonlinear laser spectroscopy of exciton relaxation in GaAs quantum wells
(Springer-Verlag, 1991-12)
This paper describes measurements of exciton relaxation in GaAs/AlGaAs quantum well structures based on high resolution nonlinear laser spectroscopy. The nonlinear optical measurements show that low energy excitons can be ...
TOPICAL REVIEW: Flow-induced structure in colloidal suspensions
(IOP Publishing Ltd, 2005-02-02)
We review the sequences of structural states that can be induced in colloidal suspensions by the application of flow. Structure formation during flow is strongly affected by the delicate balance among interparticle forces, ...
COMMENT: Comment on 'sum rules for quantum billiards'
(IOP Publishing Ltd, 1986-12-21)
Based on work of Itzykson et al., see ibid., vol.19, no.3, p.L111-16 (1986). For a d-dimensional rectangular box the function zeta (T;s) considered by Itzykson et al. is related to Epstein's zeta function and can be written ...
General flux to a trap in one and three dimensions
(IOP Publishing Ltd, 2007-02-14)
The problem of the flux to a spherical trap in one and three dimensions, for diffusing particles undergoing discrete-time jumps with a given radial probability distribution, is solved in general, verifying the Smoluchowski-like ...
Flux to a trap
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1991-12)
The flux of particles to a single trap is investigated for two systems: (1) particles in 3D space which jump a fixed step length l (the Rayleigh flight) and are adsorbed by a spherical surface, and (2) particles on a ...
Dynamics of vorticity stretching and breakup of isolated viscoelastic droplets in an immiscible viscoelastic matrix
(Springer-Verlag, 2004-05)
The effect of droplet elasticity on transient deformation of isolated droplets in immiscible polymer blends of equal viscosity was investigated. In terms of the deformation parameter, Def*= a* − c/a* + c where a * and c ...
The efficient determination of the percolation threshold by a frontier-generating walk in a gradient
(IOP Publishing Ltd, 1986-12-21)
The frontier in gradient percolation is generated directly by a type of self-avoiding random walk. The existence of the gradient permits one to generate an infinite walk on a computer of finite memory. From this walk, the ...
Monte Carlo simulation of linear aggregate formation from CdTe nanoparticles
(IOP Publishing Ltd, 2005-04-01)
In recent works it was found that nanometre sized particles of CdTe could spontaneously reorganize into crystalline nanowires (NWs) upon controlled removal of the protecting shell of organic stabilizer in an aqueous medium. ...
Similarity of Percolation Thresholds on the HCP and FCC Lattices
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2000-02)
Extensive Monte Carlo simulations were performed in order to determine the precise values of the critical thresholds for site ( p hcp c , S =0.199 255 5±0.000 001 0) and bond ( p hcp c , B =0.120 164 0±0.000 001 0) ...
