A NanoDrop-based method for rapid determination of viability decline in suspension cultures of animal cells

Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Mélanie Hubert

We describe a rapid method for monitoring the cell growth and decline phases in suspension cultures of animal cells. During the cell growth phase, ultraviolet (UV)-absorbing components in the medium are consumed, but at later times as cells begin to die, U ...

Plasma isotopic effect on the damping rate of toroidal Alfven eigenmodes with intermediate toroidal mode numbers

Ambrogio Fasoli, Duccio Testa, Patrick Blanchard, Theodoros Panis

This paper reports on the results of recent experiments performed on the JET tokamak on toroidal Alfven eigenmodes (TAEs) with toroidal mode number (n) in the range up to vertical bar n vertical bar = 7. The stability properties of these medium-nTAEs are i ...

Novel small display using ferrofluid deformations as a visual information vector

Florent Caloz

Ferrofluids are suspensions of ferromagnetic nano-particles in a fluid carrier (typically oil). They have the property to change their shape when subjected to a magnetic field following the flux lines. Often used in design and art, the goal of this project ...

YAG:Ce nanoparticle based converter layer for white LEDs

Elison de Nazareth Matioli

Our work is devoted to the development of YAG:Ce3+ nanoparticle based films for white LEDs. Very stable suspensions of YAG:Ce nanoparticles are synthesized by a glycothermal method at relatively low temperature (300 degrees C). Protected annealing in a sil ...

Critical particle concentration in electrophoretic deposition

Stefano Mischler, Johann Michler

The role of particle concentration in electrophoretic deposition (EPD) was investigated with two different suspension systems. The first system consisted of positively charged TiO2 nanoparticles dispersed in isopropanol with 1 vol% water. The second system ...

Modeling snow drift in the turbulent boundary layer

Gian-Duri Lieberherr

The modeling of snow redistribution in turbulent conditions plays an important role for the prediction of snow accumulation and avalanche risk. For this aim two Lagrangian models, one for the suspension and one for the saltation of snow were coupled. The s ...

Dynamic behavior and vibration control of a tensegrity structure

Ian Smith, Nizar Bel Hadj Ali

Tensegrities are lightweight space reticulated structures composed of cables and struts. Stability is provided by the self-stress state between tensioned and compressed elements. Tensegrity systems have in general low structural damping, leading to challen ...

Immobilized polymer fraction in hyperbranched polymer/silica nanocomposite suspensions

Yves Leterrier, Sara Dalle Vacche, Valérie Geiser, Riccardo Ruggerone

The glass transition behavior of hyperbranched polymer (HBP) molecules with suspensions of silica and glass particles up to the concentrated regime (25 vol %) was analyzed by modulated differential scanning calorimetry (MDSC). The reversing and nonreversin ...

Rheological behavior of concentrated hyperbranched polymer/silica nanocomposite suspensions

Yves Leterrier, Valérie Geiser

The rheological behavior of two hyperbranched polymer/silica suspensions with different dispersion states, surface chemistries, and concentrations of the silica nanoparticles was investigated in terms of viscoelastic properties, activation energy for visco ...

Damping behavior of bent fiber NSOM probes in water

Dusan Vobornik

The damping behavior of bent fiber near-field scanning optical microscopy (NSOM) probes operating in tapping mode oscillation is investigated in air and water. We show that the significant drop in probe quality factor Q, which occurs at the air-water inter ...
