Bottom-up approach for the synthesis of grahene nanoribbons

The controlled synthesis of graphene nanoribbons (GNRs) is crucial to fully exploit their outstanding properties. Both the top-down and the bottom-up approaches were used to fabricate GNRs. In contrast to the top-down methods in which the GNRs are…

Fast Active Merging of Microdroplets in Microfluidic Chambers Driven by Photo-Isomerisation of Azobenzene Based Surfactants

In this work, we report on the development of a newly synthesized photoactive reversible azobenzene derived surfactant polymer, which enables active and fast control of the merging of microdroplets in microfluidic chambers, driven by a pulsed UV…

Infrared laser threshold magnetometry with a NV doped diamond intracavity etalon

We propose a hybrid laser system consisting of a semiconductor external cavity laser associated to an intra-cavity diamond etalon doped with nitrogen-vacancy color centers. We consider laser emission tuned to the infrared absorption line that is…

Antenna surface plasmon emission by inelastic tunneling

Surface plasmons polaritons are mixed electronic and electromagnetic waves. They have become a workhorse of nanophotonics because plasmonic modes can be confined in space at the nanometer scale and in time at the 10 fs scale. However, in practice,…
