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 ...
Coagulation equations with gelation
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1983-06)
Smoluchowski's equation for rapid coagulation is used to describe the kinetics of gelation, in which the coagulation kernel K ij models the bonding mechanism. For different classes of kernels we derive criteria for the ...
A hierarchical algorithm for predicting the linear viscoelastic properties of polymer melts with long-chain branching
(Springer-Verlag, 2005-01)
The “hierarchical model” proposed earlier [Larson in Macromolecules 34:4556–4571, 2001] is herein modified by inclusion of early time fluctuations and other refinements drawn from the theories of Milner and McLeish for ...
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 ...
The kinetics of cluster fragmentation and depolymerisation
(IOP Publishing Ltd, 1985-10-21)
The equation that describes fragmentation kinetics, such as that which occurs in cluster breakup and polymer chain degradation (depolymerisation), is solved for models where the rate of breakup depends upon the size of the ...
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 ...
DNA molecular configurations in flows near adsorbing and nonadsorbing surfaces
(Springer-Verlag, 2004-12)
We investigate experimentally λ-phage and T2-coliphage DNA molecules near both non-adsorbing glass and adsorbing 3-aminopropyltriethoxysilane (APTES)-coated glass surfaces in a simple steady shearing flow generated by a ...
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 ...
Exact bond percolation thresholds in two dimensions
(IOP Publishing Ltd, 2006-12-08)
Recent work in percolation has led to exact solutions for the site and bond critical thresholds of many new lattices. Here we show how these results can be extended to other classes of graphs, significantly increasing the ...
TECHNICAL NOTE: Theoretical considerations for counting nucleic acid molecules in microdevices
(IOP Publishing Ltd, 2005-01-01)
We describe the theoretical design of a microchip for the amplification, detection and counting of individual nucleic acid molecules in an ensemble of non-specific molecules. The device permits access to individual molecules ...
