Kinetics and fractal properties of the random sequential adsorption of line segments
(IOP Publishing Ltd, 1990-11-07)
The random sequential adsorption (RSA) of infinitely-thin line segments is studied by computer simulation. It is shown that the exponent for the time dependence of the surface coverage increases beyond the value 0.33, ...
Stability of coextrusion through converging dies
(Elsevier, 1991-12)
A linear stability analysis of multilayer flow of viscoelastic liquids through long, converging dies is performed by a rigorous two-dimensional analysis (2-D), as well as by a simplified one-dimensional analysis (1-D) on ...
LETTER TO THE EDITOR: Exact critical exponent for the shortest-path scaling function in percolation
(IOP Publishing Ltd, 1999-10-29)
It is shown that the critical exponent g1 related to pair-connectiveness and shortest-path (or chemical distance) scaling, recently studied by Porto et al, Dokholyan et al and Grassberger, can be found exactly in two ...
Flow-aligning and tumbling in small-molecule liquid crystals: pure components and mixtures
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-08)
The results of an experimental study to measure the tumbling parameter, λ, for various small-molecule liquid crystals and their mixtures are presented. The methods used include textural observations (twist walls), a direct ...
An explicit solution to a discrete fragmentation model
(IOP Publishing Ltd, 1992-05-07)
The discrete binary fragmentation equation is solved explicitly for a model where the net rate of breakup of a particle of size k, ak, equals (k-1)/(k+1), and the daughter-size distribution bik/ equals 2/(k-1). This system ...
Determination of chloride ion diffusion coefficients for zinc dissolution in a low temperature molten salt
(Elsevier, 1990-01)
The transport properties and stoichiometry of the zinc dissolution process in mixtures of aluminum chloride and 1-methyl-3-ethylimidazolium chloride were studied. A new mass transfer correlation for rotating cylinder ...
The origin of stress-oscillation damping during startup and reversal of torsional shearing of nematics
(Steinkopff-Verlag; Springer Science+Business Media, 1997-09)
Using a controlled-temperature shear cell mounted on a polarizing microscope, we observe the behavior of nematic 4,4′- n -octyl-cyanobiphenyl (8CB) during start-up and reversal of shearing in a torsional parallel-plate ...
Traces of the arrival history in the jammed state of random sequential adsorption
(IOP Publishing Ltd, 1994-09-21)
In the final jammed state of the random sequential adsorption of dimers on a one-dimensional lattice, the average gap neighbouring a particle that originally adsorbed at time t is e-te-ee(-tt). Thus, the average final gap ...
Determination of the bond percolation threshold for the Kagomé lattice
(IOP Publishing Ltd, 1997-08-07)
The hull-gradient method is used to determine the critical threshold for bond percolation on the two-dimensional Kagomé lattice (and its dual, the dice lattice). For this system, the hull walk is represented as a self-avoiding ...
“Fracture” phenomena in shearing flow of viscous liquids
(Steinkopff-Verlag; Springer Science+Business Media, 1997-09)
In start-up of steady shearing flow of two viscous unentangled liquids, namely low-molecular-weight polystyrene and α-D-glucose, the shear stress catastrophically collapses if the shear rate is raised above a value ...
