Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
We report arrays of latching microfluidic valves based on shape memory polymers (SMPs), and show their applications as reagent mixers and as peristaltic pumps. The valve design takes advantage of the SMP's multiple stable shapes and over a hundred-fold sti ...
It is in the context of miniaturization that arises the microfluidics concept. It is not uncommon in chemical, biological or medical analysis laboratories to manipulate or to mix fluids while measuring the results with filters, spectrometers or all other e ...
The nematode Caenorhabditis elegans is an attractive model organism, owing notably to its short life cycle, genetic tractability, and optical transparency facilitating microscopic observation. This thesis deals with the realization of technological tools f ...
Pressure lies at the basis of operation of most microfluidic systems, and is a determinant factor in the extent of miniaturization and in limiting the throughput and time constant of the microfluidic assays. Despite the apparent importance given to fluidic ...
Passive flow regulators are usually intended to deliver or drain a fluid at a constant rate independently from pressure variations. Microfluidic devices made of a stack of two plates are considered here: the first plate comprises a flexible silicon membran ...
Cavitation and the energy associated with the collapse of resulting cavitation bubbles constitute an important research subject. The collapse of the hydrodynamic cavitation bubbles at the outlet of the flow elements leads to a high energy release and gener ...
We demonstrate data storage on glass/silicon microfluidic devices fabricated using parylene-C as a bonding layer. In particular, we report intermediate parylene-C bonding layer fluorescence (iPBLF) and its use as an on-chip medium for data storage by dynam ...
This paper describes a reproducible method for μm precision alignment of polydimethylsiloxane (PDMS) microchannels with coplanar electrodes using a conventional mask aligner for lab-on-a-chip applications. It is based on the use of a silicon mold in combin ...
Double emulsions are often used as containers to perform high throughput screening assays and as templates for capsules. These applications require double emulsions to be mechanically stable such that they do not coalesce during processing and storage. A p ...
The main objective of this study was to develop further insight into the mass flux characterization of an effervescent atomization. The spray is injected through an industrial effervescent nozzle, and is measured using a newly developed coupled PDPA + IS m ...
