Surface charging behavior of nanoparticles by considering site distribution and density, dielectric constant and pH changes – a Monte Carlo approach

Marianne Seijo, Serge Stoll, Fabrice Carnal

Monte Carlo simulations are used to describe the charging behavior of metal oxide nanoparticles thus enabling a novel and original approach to predict nanoparticle reactivity and the possible interactions with biological and environmental molecules. The ch ...

Inﬂuence of a wastewater treatment plant on mercury contamination and sediment characteristics in Vidy Bay (Lake Geneva, Switzerland)

Yosef Akhtman, Serge Stoll, Neil Graham

Previous direct observations of the sediment surface in Vidy Bay, Lake Geneva (Switzerland), revealed a range of sediment characteristics in terms of colour, texture and morphology. Dives with the MIR submersibles during the éLEMO project permitted the exp ...

Formation of Complexes between Nanoparticles and Weak Polyampholyte Chains. Monte Carlo Simulations

Marianne Seijo, Serge Stoll, Fabrice Carnal

The electrostatic driven complex formation between a weak polyampholyte chain and one pos. charged nanoparticle is investigated using Monte Carlo simulations. The influence of parameters such as the polyampholyte contour length, no. and size of blocks, nan ...

Modeling the Adsorption and Coagulation of Fulvic Acids on Colloids by Brownian Dynamics Simulations

Marianne Seijo, Montserrat Filella, Serge Stoll

Humic substances (HS) play an important role in the reactivity and transport of colloids in natural environments. In particular, the presence of fulvic acids (FA) in natural waters modifies the interactions between inorg. particles and biopolymers and make ...

Modeling the surface charge evolution of spherical nanoparticles by considering dielectric discontinuity effects at the solid/electrolyte solution interface

Marianne Seijo, Montserrat Filella, Serge Stoll

It is well known that the electrostatic repulsions between charges on neighboring sites decrease the effective charge at the surface of a charged nanoparticle (NP). However, the situation is more complex close to a dielec. discontinuity, since charged site ...

A Monte Carlo Study of Weak Polyampholytes: Stiffness and Primary Structure Influences on Titration Curves and Chain Conformations

Marianne Seijo, Serge Stoll

The conformation and titrn. curves of weak polyampholytes are examd. using Monte Carlo simulations with screened Coulomb potentials in the Grand Canonical ensemble. Two different types of monomers are considered. Depending on the soln. pH, monomers A are w ...

Conformational Changes and Aggregation of Alginic Acid as Determined By Fluorescence Correlation Spectroscopy

Marianne Seijo, Fabrice Avaltroni, Serge Stoll

Insight into the conformations and aggregation of alginic acid was gained by measuring its diffusion coefficient at very dilute concentrations using fluorescence correlation spectroscopy. Both the pH and ionic strength (I) had an important influence on the ...

Effects of surface site distribution and dielectric discontinuity on the charging behavior of nanoparticles. A grand canonical Monte Carlo study

Marianne Seijo, Montserrat Filella, Serge Stoll

The surface site distribution and the dielec. discontinuity effects on the charging process of a spherical nanoparticle (NP) have been investigated. It is well known that electrostatic repulsion between charges on neighboring sites tends to decrease the ef ...
