Numerical analysis of electroosmotic flow in dense regular and random arrays of impermeable, nonconducting spheres.

Langmuir : the ACS journal of surfaces and colloids

Hlushkou D, Seidel-Morgenstern A, Tallarek U.
PMID: 15952866
Langmuir. 2005 Jun 21;21(13):6097-112. doi: 10.1021/la050239z.

We present a numerical scheme for analyzing steady-state isothermal electroosmotic flow (EOF) in three-dimensional random porous media, involving solution of the coupled Poisson, Nernst-Planck, and Navier-Stokes equations. While traditional finite-difference methods were used to resolve the Poisson-Nernst-Planck problem, the...

PMID: 19921775
Anal Chem. 2009 Dec 15;81(24):10149-55. doi: 10.1021/ac901913r.

Bipolar electrode focusing at discontinuous bipolar electrodes (BPEs) provides new insight into the faradaic current and electric field characteristics associated with the technique and allows for the controlled transport of a focused anionic tracer in a microfluidic channel. The...

Transient effects on microchannel electrokinetic filtering with an ion-permselective membrane.

The electrokinetics and hydrodynamics in a hybrid microfluidic/nanofluidic pore network configuration and its effect on the concentration enrichment of charged analytes are described. A hydrogel microplug, photopolymerized in a microfluidic channel, with negative surface charge serves as a nanoporous...

Effect of adsorption on solute dispersion: a microscopic stochastic approach.

Analytical chemistry

Anal Chem. 2014 May 06;86(9):4463-70. doi: 10.1021/ac500309p. Epub 2014 Apr 17.

We report on results obtained with a microscopic modeling approach to Taylor-Aris dispersion in a tube coupled with adsorption-desorption processes at its inner surface. The retention factor of an adsorbed solute is constructed by independent adjustment of the adsorption...

Crack Initiation of Printed Lines Predicted with Digital Image Correlation.

JOM (Warrendale, Pa. : 1989)

Katsarelis C, Glushko O, Tonkin C, Kennedy MS, Cordill MJ.

Printing of metallic films has been preferred over vacuum technologies for roll-to-roll processes because of faster processing times and lower processing costs. Films can be produced by depositing inks containing suspended metallic particles within a solvent and then heating...

Morphology of Fluids Confined in Physically Reconstructed Mesoporous Silica: Experiment and Mean Field Density Functional Theory.

Langmuir : the ACS journal of surfaces and colloids

Svidrytski A, Rathi A, Hlushkou D, Ford DM, Monson PA, Tallarek U.
PMID: 30070853
Langmuir. 2018 Aug 28;34(34):9936-9945. doi: 10.1021/acs.langmuir.8b01971. Epub 2018 Aug 16.

Three-dimensional physical reconstruction of the random mesopore network in a hierarchically structured, macroporous-mesoporous silica monolith via electron tomography has been used to generate a lattice model of amorphous, mesoporous silica. This geometrical model has subsequently been employed in mean...

Exact theory of the four-wave-mixing process in a nondissipative medium with a large rate of conversion: Weak-field case.
