Crossover from fast relaxation to physical aging in colloidal adsorption at fluid interfaces

open access: yes, 2012
The adsorption dynamics of a colloidal particle at a fluid interface is studied theoretically and numerically, documenting distinctly different relaxation regimes.

Monte Carlo simulations of interfaces in polymer blends

open access: yes, 1998
We review recent simulation studies of interfaces between immiscible homopolymer phases. Special emphasis is given to the presentation of efficient simulation techniques and powerful methods of data analysis, such as the analysis of capillary wave ...

Diblock copolymers at a homopolymer-homopolymer-interface: a Monte Carlo simulation [PDF]

open access: yes, 1996
The properties of diluted symmetric A-B diblock copolymers at the interface between A and B homopolymer phases are studied by means of Monte Carlo (MC) simulations of the bond fluctuation model.

SURFACE TENSION AND INTERFACIAL FLUCTUATIONS IN d-DIMENSIONAL ISING MODEL [PDF]

open access: yesInternational Journal of Modern Physics C, 2005
The surface tension of rough interfaces between coexisting phases in 2D and 3D Ising models are discussed in view of the known results and some original calculations presented in this paper. The results are summarized in a formula, which allows to interpolate the corrections to finite-size scaling between two and three dimensions. The physical meaning

Imaging spectroscopy of quantum wells with interfacial fluctuations: A theoretical description [PDF]

open access: yesApplied Physics Letters, 2000
We present a theoretical approach for the simulation of scanning local optical spectroscopy in disordered quantum wells (QWs). After a single realization of the disorder potential, we calculate spectra on a mesh of points on the QW plane, thus obtaining a three-dimensional matrix of data from which we construct two-dimensional spectroscopic images of ...

Coupled Hamiltonians and Three Dimensional Short-Range Wetting Transitions

open access: yes, 1997
We address three problems faced by effective interfacial Hamiltonian models of wetting based on a single collective coordinate \ell representing the position of the unbinding fluid interface.

Interfacial fluctuations in an ideal block copolymer resist

open access: yesSoft Matter, 2009
We use field-theoretic computer simulations to show that intrinsic interfacial fluctuations may place limits on the use of block copolymer materials as resists for the nanofabrication of next-generation electronics devices. Even for an ideal system, our simulations demonstrate that the magnitude of the interfacial fluctuations is of the same order as ...

FINITE ELEMENT ANALYSIS OF FRACTURE MECHANICS OF WHEEL-RAIL [PDF]

open access: yesمجله مدل سازی در مهندسی, 2011
In this paper, wheel-rail contact problem in the presence of rail surface crack is investigated. The reason for investigating this problem is significant effect of wheel-rail contact on stress intensity factors.

Electrical Properties of PAN/PMMA Blends Doped with Lithium Salts

open access: yesIraqi Journal of Physics, 2022
         Polymer blended electrolytes of various concentrations of undoped PAN/PMMA (80/20, 75/25, 70/30, 65/35 and 60/40 wt%) and doped with lithium salts (LiCl, Li2SO4H2O, LiNO3, Li2CO3) at 20% wt have been prepared by the solution casting method ...
