Critical issues in using the common mixture toxicity models concentration addition or response addition on species sensitivity distributions: A theoretical approach

The risk of chemical mixtures to ecosystems is often assessed by applying the model of concentration addition or response addition combined with species sensitivity distribution (SSD) curves. Mixture effect predictions have been shown to be consistent only ...

Analytic Sensing For Multi-Layer Spherical Models With Application To EEG Source Imaging

Dimitri Nestor Alice Van De Ville, Thierry Blu, Djano Kandaswamy

Source imaging maps back boundary measurements to underlying generators within the domain; e. g., retrieving the parameters of the generating dipoles from electrical potential measurements on the scalp such as in electroencephalography (EEG). Fitting such ...

Evaluating mixture adsorption models using molecular simulation

Berend Smit, Ji Hyun Kim

The design of adsorption-based separation processes using novel adsorbents requires reliable data for the adsorption of fluid mixtures on candidate adsorbents. Due to the difficulty of generating sufficient data across possible operating conditions, proces ...

Gas injection tests on a Sand Bentonite Mixture: Investigation on the effects of pore water chemistry

Lyesse Laloui, Alessio Ferrari, Donatella Manca, Mohammad Monfared

In this study a series of swelling and breakthrough tests were performed on a target S/B mixture in proportion 80/20 in dry mass. Tests were carried out on specimen compacted to the same dry density but changing the osmotic suction of the pore water. The t ...

A microchip emitter for solid phase extraction – gradient elution – mass spectrometry

Hubert Girault, Natalia Gasilova, Liang Qiao, Dmitry Momotenko, Mohammad Reza Pourhaghighi

A microchip electrospray emitter with a magnetic bead trap has been designed for solid phase extraction-gradient elution-mass spectrometry (SPE-GEMS). The goal of this method is the detection of analytes at low concentrations and it is here demonstrated us ...

Size and synergy effects of nanofiller hybrids including graphene nanoplatelets and carbon nanotubes in mechanical properties of epoxy composites

We study mechanical reinforcement in a widely used epoxy matrix with the addition of graphene nanoplatelets (GnPs) and various mixture ratios of carbon nanotubes (CNTs) with GnPs. Two different dimensions of GnPs were used with flake sizes of 5 mu m and 25 ...

Sodium dodecyl sulfate at water-hydrophobic interfaces: A simulation study

Sylvie Roke

Using molecular dynamics simulations, we have studied the water-vapor and water-oil (decane) interfaces of aqueous solutions of sodium dodecyl sulfate (SDS). The water-vapor interface is often used as a model for water-oil (hydrophobic) interfaces, yet we ...

Movement of Artificial Bacterial Flagella in Heterogeneous Viscous Environments at the Microscale

Lei Zhang

Swimming microrobots have the potential to be used in medical applications such as targeted drug delivery. The challenges for navigating microrobots in the human body lie not only in the viscosity of body fluids but also in the existence of different types ...
