Efficient Separation of Long Polymer Chains by Contour Length and Architecture

Autor: Andrey Milchev, A.M. Skvortsov, Leonid I. Klushin

Publikováno v: ACS macro letters. 2(10)

On the basis of theoretical considerations and computer experiment, we suggest a new technique for separation of polymer molecules. The method is based on filling an array of nanochannels with macromolecules whereby the subsequent ejection time depen

Polydisperse Brush with the Linear Density Profile

Autor: Shuanhu Qi, Leonid I. Klushin, Friederike Schmid, A.M. Skvortsov

Publikováno v: Polymer Science, Series C. 60:84-94

Macromolecules densely end-grafted to a planar solid surface form a polymer monolayer (brush). It is known that, in a good solvent, the density profile of monodisperse brushes parabolically decays on moving away from the plane. Using the analytical t

Ejection of a Polymer Chain from a Nanopore: Theory and Computer Experiment

Autor: Kurt Binder, A. Milchev, Leonid I. Klushin, A.M. Skvortsov

Publikováno v: Macromolecules. 43:6877-6885

We consider the ejection dynamics of a flexible polymer chain out of confined environment. This situation arises in different physical contexts, including a flexible synthetic polymer partially confined in a nanopore and a viral genome partially ejec

Theory for concentration and solvency effects in size-exclusion chromatography of polymers

Autor: G.J. Fleer, A.M. Skvortsov

Publikováno v: Macromolecules, 38(6), 2492-2505
Macromolecules 38 (2005) 6

A simple analytical equation for the distribution coefficient K in size-exclusion chromatography (SEC) as a function of molar mass, concentration, and solvent quality is presented. The theory is based upon a modified Casassa equation, using a recentl

First-order coil-to-flower transition of a polymer chain pinned near a stepwise external potential: Numerical, analytical, and scaling analysis

Autor: A.M. Skvortsov, Leonid I. Klushin, J. van Male, Frans A. M. Leermakers

Publikováno v: Journal of Chemical Physics, 115, 1586-1595
Journal of Chemical Physics 115 (2001)

A polymer chain near a penetrable interface is studied in the Gaussian model, in the lattice random walk model and by a scaling analysis. The interface is modeled as an external potential u of a Heaviside step-function form. One end of the chain is f

Mapping of continuum and lattice models for describing the adsorption of an ideal chain anchored to a planar surface

Autor: Alexei A. Gorbunov, A.M. Skvortsov, J. van Male, G.J. Fleer

Publikováno v: Journal of Chemical Physics 114 (2001)
Journal of Chemical Physics, 114, 5366-5375

An ideal polymer chain anchored to a planar surface is considered by using both lattice and continuum model approaches. A general equation relating the lattice and continuum model adsorption interaction parameters is derived in a consistent way by su

The rolling transition of a Gaussian chain end-grafted at a penetrable surface

Autor: Leonid I. Klushin, J. van Male, Frans A. M. Leermakers, A.M. Skvortsov

Publikováno v: The Journal of Chemical Physics. 112:7238-7246

A Gaussian chain at a liquid–liquid interface is considered. The solvents are represented by an external potential field u that has a constant value in one half-space and is zero elsewhere. One end of the chain is fixed at the boundary where the ex
