Publikováno v: International Journal of Non-Linear Mechanics. 42:673-680

The first part of this paper gives a theoretical study of the mechanics of contact of an AFM tip on viscous materials. Analytical expressions are derived showing the non-linear behaviors specifically related to the use of dynamic operation modes of A

The dynamical behaviour of an entangled network, a melt made of long polymer chains, with an oscillating nanotip, is investigated to provide evidence for a close relationship between the spatial scale and dynamics of the network, from the molecular t

Numerous new drug candidates fail because of inadequate pharmacokinetics. Positron emission tomography (PET) enables the noninvasive characterization of the drug in humans and animals. The aim of the present work was the comparison of methods for the

International audience; Evaporation processes are a common feature in micro and nanofluidics where aqueous solutions are employed. Evaporation can be used as the driving phenomenon to control laminar flows in microchannels. The present analysis shows

Introduction La barriere hemato-encephalique (BHE) constitue une des limites de l’efficacite des chimiotherapies cerebrales. Depuis peu, nous savons que les ultrasons focalises, associes a un agent de contraste ultrasonore, peuvent ouvrir la BHE de
