Graph Chatbot

Chattez avec Graph Search

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.

On the Design of Highly Luminescent Lanthanide Complexes

Jean-Claude Bünzli

Presently, phosphors and luminescent materials for lighting, telecommunications, displays, security inks and marking, as well as for probes in biosciences represent one third of the total value of the lanthanides used worldwide. If optical glasses and lase ...

Effect of the thin-film limit on the measurable optical properties of graphene

Christophe Ballif, Stefaan De Wolf, Sylvain Nicolay, Jakub Holovsky

The fundamental sheet conductance of graphene can be directly related to the product of its absorption coefficient, thickness and refractive index. The same can be done for graphene's fundamental opacity if the so-called thin-film limit is considered. Here ...

Optical microscopy using a glass microsphere for metrology of sub-wavelength nanostructures

Martinus Gijs, Hui Yang

A technique that allows direct optical imaging of nanostructures and determines quantitatively geometric nanofeatures beyond the classical diffraction limit by using high-refractive index glass microspheres is introduced. The glass microsphere is put on a ...

Optical properties of anthocyanins in the gas phase

The gas-phase optical properties of the six most common anthocyanins are studied using time-dependent density-functional theory. Different anthocyanins are classified into three groups, according to the number of low-frequency peaks displayed in the UV-vis ...

Optical forces in nanoplasmonic systems: how do they work, what can they be useful for?

Olivier Martin, Raziman Thottungal Valapu, Robert Julius Wolke

n this article, we share our vision for a future nanofactory, where plasmonic trapping is used to control the different manufacturing steps associated with the transformation of initial nanostructures to produce complex compounds. All the different functio ...

Direct-write diffracting tubular optical components using femtosecond lasers

Yves Bellouard

Over the last decade, femtosecond lasers have been used extensively for the fabrication of optical elements via direct writing and in combination with chemical etching. These processes have been an enabling technology for manufacturing a variety of devices ...

Optical microscopy for biology and life sciences

Theo Lasser, Marcel Leutenegger

Optical microscopy has become a major non- or minimally invasive tool for investigating living organisms such as cells, tissues or small animals. Being such an essential tool for research and because lacking knowledge and insight in the working principles ...

Handheld high-throughput plasmonic biosensor using computational on-chip imaging

Hatice Altug, Arif Engin Cetin, Min Huang

We demonstrate a handheld on-chip biosensing technology that employs plasmonic microarrays coupled with a lens-free computational imaging system towards multiplexed and high-throughput screening of biomolecular interactions for point-of-care applications a ...
