Reptational dynamics in dissipative particle dynamics simulations of polymer melts
P. Nikunen, I. Vattulainen, M. Karttunen
Understanding the complex viscoelastic properties of polymeric liquids remains a challenge in materials science and soft matter physics. Here, we present a simple and computational…
Dielectrophoresis of nanocolloids: a molecular dynamics study
E. Salonen, E. Terama, I. Vattulainen +1
Dielectrophoresis (DEP), the motion of polarizable particles in non-uniform electric fields, has become an important tool for the transport, separation, and characterization of mic…
Molecular Dynamics Study of Charged Dendrimers in Salt-Free Solution: Effect of Counterions
Andrey A. Gurtovenko, Sergey V. Lyulin, Mikko Karttunen +1
Polyamidoamine (PAMAM) dendrimers, being protonated under physiological conditions, represent a promising class of nonviral, nano-sized vectors for drug and gene delivery. We perfo…
Spectral representation of the effective dielectric constant of graded composites
L. Dong, Mikko Karttunen, K. W. Yu
We generalize the Bergman-Milton spectral representation, originally derived for a two-component composite, to extract the spectral density function for the effective dielectric co…
