Fabrication of suspended microchannel resonators for biosensing application

Some diseases are characterized at the biomolecular level by a change in the mechanical properties of the cells in comparison to normal cells. Detecting this change could thus be useful for biomedical pplications. Micromechanical sensors are devices that a ...

Anomalous Vp/Vs ratios at seismic frequencies might evidence highly damaged rocks in subduction zones

Marie Estelle Solange Violay, Lucas Xan Pimienta

Unusually high compressional (P) to shear (S) wave velocity ratios (V-p/V-s) were measured at different subduction zones and interpreted as fluid-pressurized regions. Because no laboratory data reported such high values in isotropic rocks, mineralogical or ...

Interface-fitted moving mesh method for axisymmetric two-phase flow in microchannels

John Richard Thome, Gustavo Rabello Dos Anjos, Erik Gros

A boundary-fitted moving mesh scheme is presented for the simulation of two-phase flow in two-dimensional and axisymmetric geometries. The incompressible Navier-Stokes equations are solved using the finite element method, and the mini element is used to sa ...

Real-gas effects on aerodynamic bearings

Jürg Alexander Schiffmann, Eliott Philippe Guenat

Motivated by the use of aerodynamic bearings lubricated with high-pressure gases in energy conversion cycles, the Reynolds equation is adapted in order to include effects of real-gas and turbulence. Three geometries (Rayleigh-step slider, plain and herring ...

Photopolymerizable bone filler material

Dominique Pioletti, Andreas Schmocker, Oriane Poupart

A photopolymerizable bone filler material comprising a fluid polymeric material, a photoinitiator and a plurality of solid, polymeric optical fibers is disclosed, wherein said optical fibers are used for both illumination and reinforcement of the entire ph ...

A semi-infinite hydraulic fracture driven by a shear-thinning fluid

Brice Tanguy Alphonse Lecampion, Fatima-Ezzahra Moukhtari

We use the Carreau rheological model which properly accounts for the shear-thinning behaviour between the low and high shear rate Newtonian limits to investigate the problem of a semi-infinite hydraulic fracture propagating at a constant velocity in an imp ...

The impact of the volumetric swelling behavior on the water uptake of gas shale

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

Water uptake of gas shales is commonly considered one of the most important factors responsible for fluid loss during flowback operations after hydraulic fracturing. Imbibition experiments cover a key role in this context to analyze the impact of several f ...

Micromotion-induced peri-prosthetic fluid flow around a cementless femoral stem

Dominique Pioletti, Alexandre Terrier, Valérie Hélène Emilie Malfroy Camine

Micromotion-induced interstitial fluid flow at the bone-implant interface has been proposed to play an important role in aseptic loosening of cementless implants. High fluid velocities are thought to promote aseptic loosening through activation of osteocla ...

Energy dissipation in Suspended Microchannel Resonators as function of channel off-axis placement

Annalisa De Pastina, Mauricio Lucena Couto

Suspended Microchannel Resonators (SMRs) enable real time analysis of fluidic samples with almost no degradation of the quality factor. - Energy dissipation is a non-monotonic function of the fluid viscosity. - Quality factor is highly dependent on the mic ...
