Continuous separation of cells by balanced dielectrophoretic forces at multiple frequencies

Philippe Renaud, Thomas Michael Braschler, Nicolas Demierre

We present a particle-sorting device based on the opposition of dielectrophoretic forces. The forces are generated by an array of electrode chambers located in both sidewalls of a main flow channel. Particles with different dielectric response perceive dif ...

Experimental investigation on temperature-dependent thermo- physical and mechanical properties of pultruded GFRP composites

Thomas Keller, Yu Bai

The temperature-dependent thermo-physical and mechanical properties of a pultruded E-glass fiber-reinforced polyester (GFRP) composite are investigated in this paper. Fitting of theoretical models of the material properties to results of TGA, DSC, hot disk ...

Adsorption of Superplasticizers on a Model Powder

Paul Bowen, François Perche

Adsorption isotherms of carboxylate type superplasticizers with different architectures have been measured on MgO considered as a non-reactive model powder. This system allowed us to study the influence of pH, electrolyte type, concentration and ionic stre ...

Asymmetrical flow field-flow fractionation coupled to multi-angle light scattering detector: optimization of crossflow rate, carrier characteristics and injected mass in alginate separation

Vera Slaveykova-Startcheva

The coupling of the flow field flow fractionation to differential refractive index (DRI) and multi-angle laser light scattering detectors is a powerful tool for characterizing charged polysaccharides such as alginate. However, the correct interpretation of ...

Asymmetrical Flow Field Flow Fractionation–Multidetection System as a Tool for Studying Metal – Alginate Interaction

Vera Slaveykova-Startcheva

The present study explores the potential use of asymmetrical flow field flow fractionation (aFlFFF) with a multidetection system for the study of metal–alginate interactions. aFlFFF, coupled on-line to a differential refractive index and seven angle laser ...

Polyelectrolyte complex formation at defined interfaces and structure formation in solution studied by analytical ultracentrifugation

Laurent Bourdillon

The interactions and structural formation of polyelectrolytes in solution and environmental stimuli-responsive water-soluble polymers are subjects of intense academic research, development, and application. An increasing number of novel materials are being ...

Effect of microcapsule composition and short-term immunosuppression on intraportal biocompatibility

Jutta Christine Wandrey, David Hunkeler, Dianelys Sainz Vidal

With higher nutrient and oxygen supply and close contact to blood, the portal vein is a possible alternative to the peritoneal cavity for transplantation of encapsulated cells. Data regarding intraportal biocompatibility of microcapsules are lacking. Micro ...
