Simulation and theory of fluid demixing and interfacial tension of mixtures of colloids and non-ideal polymers [PDF]

open access: yes, 2005
An extension of the Asakura-Oosawa-Vrij model of hard sphere colloids and non-adsorbing polymers, that takes polymer non-ideality into account through a repulsive stepfunction pair potential between polymers, is studied with grand canonical Monte Carlo ...

New Polymer Tensiometers: Measuring Matric Pressures Down to the Wilting Point [PDF]

open access: yes, 2007
Tensiometers are commonly used for measuring soil water matric pressures. Unfortunately, the water-filled reservoir of conventional tensiometers limits their applicability to soil water matric pressures above approximately –0.085 MPa. Tensiometers filled

Polymer Translocation Through a Long Nanopore

open access: yes, 2002
Polymer translocation through a nanopore in a membrane investigated theoretically. Recent experiments on voltage-driven DNA and RNA translocations through a nanopore indicate that the size and geometry of the pore are important factors in polymer ...

Localization and diffusion in polymer quantum field theory

open access: yes, 2014
Polymer quantization is a non-standard approach to quantizing a classical system inspired by background independent approaches to quantum gravity such as loop quantum gravity.

In-situ measurements of the optical absorption of dioxythiophene-based conjugated polymers

open access: yes, 2011
Conjugated polymers can be reversibly doped by electrochemical means. This doping introduces new sub-bandgap optical absorption bands in the polymer while decreasing the bandgap absorption. To study this behavior, we have prepared an electrochemical cell

Globule-like conformation and enhanced diffusion of active polymers [PDF]

open access: yes, 2018
We study the dynamics and conformation of polymers composed by active monomers. By means of Brownian dynamics simulations we show that when the direction of the self-propulsion of each monomer is aligned with the backbone, the polymer undergoes a coil-to-

Surface segregation of conformationally asymmetric polymer blends

open access: yes, 2006
We have generalized the Edwards' method of collective description of dense polymer systems in terms of effective potentials to polymer blends in the presence of a surface.

Colloid-Induced Polymer Compression [PDF]

open access: yes, 2002
We consider a model mixture of hard colloidal spheres and non-adsorbing polymer chains in a theta solvent. The polymer component is modelled as a polydisperse mixture of effective spheres, mutually noninteracting but excluded from the colloids, with ...

Conductividad iónica en nuevos compositos (PEO)10(CF3COONa)-X % Al2O3 [PDF]

open access: yesUniversitas Scientiarum, 2013
To increase the ionic conductivity of solid polymer electrolyte, (PEO)10CF3COONa, we formed new composites by adding alumina particles as a filler.

FERROCENYL ALKYLAMMONIUM N-SUBSTITUTED POLYPYRROLE CONTAINING Pt AND Pd AND ITS APPLICATION ON ELECTROANALYSIS OF ARSENITE [PDF]

open access: yes, 2016
Indexación: Web of Science; Scopus; Scielo.Arsenic occurs in a variety of forms and oxidation states and is a very toxic element. The main inorganic arsenic species present in natural waters are arsenate (oxidation state V) and arsenite ions (oxidation ...
