Lorsque nous concevons des produits portables, appelés "Smart Textile", le textile est surtout utilisé comme support pour établir un lien entre l'utilisateur et la technologie : c'est le bracelet d'une montre électronique, ou la chemise où des capteurs ont été branchés. Les attributs électroniques sont souvent ajoutés pour augmenter les performance...

Polymer brushes of Poly(N-isopropyl acrylamide) (p-NIPAM) are a well-studied system, finding application as a functional polymer due to its thermally activated transition from an expanded to a collapsed state at 32oC. Performing conventional “static” AFM force spectroscopy in water on a p-NIPAM brush using sharp probes reveals distinctive behavior...

This is truly a masterpiece of Design. We even do not not...

Les poussières sont partout. Chacune est imperceptible mais elles sont néanmoins toujours présentes et s'imposent dans nos vies.

It was shown recently that the Force Feedback Microscope can avoid the jump-to-contact in Atomic force Microscopy even when the cantilevers used are very soft, thus increasing force resolution. In this letter, we explore theoretical aspects of the associated real time control of the tip position. We take into account lever parameters such as the le...

Owing to its two-dimensional electronic structure, graphene exhibits many unique properties. One of them is a wave vector and temperature dependent plasmon in the infrared range. Theory predicts that due to these plasmons, graphene can be used as a universal material to enhance nanoscale radiative heat exchange for any dielectric substrate. Here we...

The control of heat flow is a formidable challenge due to lack of good thermal insulators. Promising new oppor-tunities for heat flow control were recently theoretically discovered for radiative heat flow in near field, where large heat flow contrasts may be achieved by tuning electronic excitations on surfaces. Here we show experi-mentally that th...

Thus, an object of an embodiment of the present invention is to provide a device which overcomes at least some of the disadvantages of prior devices, that is, in particular: which enables to use a relatively large distance between the tip of an optical fiber and the surface to be analyzed, which requires no height control of the fiber, and which is...

The force between two interacting particles as a function of distance is one of the most fundamental curves in science. In this regard, Atomic Force Microscopy (AFM) represents the most powerful tool in nanoscience but with severe limits when it is to probe attractive interactions with high sensitivity. The Force Feedback Microscope (FFM) described...

It is shown that a graphene layer on top of a dielectric slab can dramatically influence the ability of this dielectric for radiative heat exchange. Effect of graphene is related to thermally excited plasmons. Frequency of these resonances lies in the terahertz region and can be tuned by varying the Fermi level through doping or gating. Heat transf...

We report on measurements of the Casimir force in a sphere-plane geometry using a cryogenic force microscope to move the force probe in situ over different materials.

Micro electromechanical systems (MEMS) and mechanical effects of quantum fluctuations become strongly related. MEMS have allowed the production of important experimental results such as quantitative measurements of the Casimir force at the micro- and nanoscales. MEMS are used to probe these effects because they are sensitive to them and engineers w...

We show numerically that near field heat flux can be modulated by orders of magnitude upon switching from the metallic to the insulating phase of vanadium dioxide. Furthermore the resonant phonon polariton interaction for the insulating phase enhances near field thermal transfer by 3 orders of magnitude. The effect should therefore be measureable w...

We study the slippage of a gas along mobile rigid walls in the sphere-plane confined geometry and find that it varies considerably with pressure. The classical no-slip boundary condition valid at ambient pressure changes continuously to an almost perfect slip condition in a primary vacuum. Our study emphasizes the key role played by the mean free p...

We introduce a concept for electrically controlled heat-flux modulation. A flux contrast larger than 10 dB is expected with switching time on the order of tens of nanoseconds. Heat-flux modulation is based on the interplay between radiative heat transfer at the nanoscale and phase-change materials. Such large contrasts are not obtainable in solids,...
