Experimental studies on evaporation kinetics of gold nanofluid droplets: Influence of nanoparticle sizes and coating on thermal performance

Ibrahim Zaaroura, Souad Harmand, Julien Carlier, Malika Toubal, Aurélie Fasquelle, Bertrand Nongaillard

In this work, a series of experiments investigate the evaporation of gold nanofluid sessile droplets on a perfluorodecyltrichlorosilane (PFTS) silicon substrate heated to 77 °C. The evaporation processes of different nanofluid droplets of the same initial volume, all for a 1% Cv volume…

Microfluidic Culture Model for Drug Screening on Schistosome Parasites

Vincent Girod, Marie-Jose Ghoris, Jérôme Vicogne, Vincent Senez

Schistosomiasis is a challenging parasitic model due to the absence of transgenic strains and systems allowing maintenance of heathy worms outside of their host (mammals). Classical in vitro studies (Petri dish) do not allow long-term survival of worm couples with retention of basic biological…

300 GHz link enabled by Yagi-Uda antenna

Guillaume Ducournau, Fabio Pavanello, Cybelle Belem-Gonçalves, Frédéric Gianesello, Cyril Luxey, Emilien Peytavit, Jean-Francois Lampin, Malek Zegaoui, Mohammed Zaknoune

This paper presents the use of a Yagi-Uda antenna on polymer substrate for 300 GHz data communications. The antenna is described and characterized in terms of radiation pattern in the 300 GHz band. Then, it is used and validated within a communication link. Using amplitude shift keying modulation…

Thèse

Structure and electronic properties of Ge-based 2D crystals, Structure et propriétés électroniques des matériaux 2D à base de germanium

Davide Sciacca

In this thesis, we have studied the properties of two 2D materials made of germanium: germanene, the equivalent of graphene, and a multilayer stack of germanene terminated with methyl groups. Due to a buckled atomic structure and a strong spin orbit coupling, these materials stand out from graphene…, Dans cette thèse, nous avons étudié les propriétés de deux matériaux 2D constitués de germanium : le germanène, l'équivalent du graphène, et un empilement multicouche de germanane à terminaison méthyle. En raison d’une structure atomique gauchie et d’un couplage spin orbite important, ces…

Impulsive Noise Modeling and Robust Receiver Design

Laurent Clavier, Gareth W Peters, François Septier, Ido Nevat

Interference is an important limitation in many communication systems. It has been shown in many situations that the popular Gaussian approximation is not adequate and interference exhibits an impulsive behavior. This paper surveys the different statistical models proposed for such an interference…

Thèse

Electronic and transport properties of epitaxially connected quantum dot superlattices, Propriétés électroniques et de transport des super-réseaux de boites quantiques épitaxiallement connectées

Vincent Notot

Semiconductor colloidal quantum dots are fluorescent semiconductors of nanometric size, generally between 2 and 10 nm. These materials have raised the interest of the scientific community for more than thirty years because of their particular opto-electronic properties, which result from the strong…, Les boites quantiques colloïdales semiconductrices sont des semi-conducteurs fluorescents de taille nanométrique, généralement comprises entre 2 et 10 nm. Ces matériaux ont suscité l'intérêt de la communauté scientifique depuis plus de trente ans en raison de leurs propriétés opto-…

Neurons with dendrites can perform linearly separable computations with low resolution synaptic weights

Romain Caze, Marcel Stimberg

In theory, neurons modelled as single layer perceptrons can implement all linearly separable computations. In practice, however, these computations may require arbitrarily precise synaptic weights. This is a strong constraint since both biological neurons and their artificial counterparts have to…

Ferroelectric Gating of Narrow Band-Gap Nanocrystal Arrays with Enhanced Light Matter Coupling

Charlie Gréboval, Audrey Chu, Debora Vale Magalhaes, Julien Ramade, Junling Qu, Prachi Rastogi, Adrien Khalili, Sang-Soo Chee, Hervé Aubin, Grégory Vincent, Sara Bals, Christophe Delerue, Emmanuel Lhuillier

As narrow band gap nanocrystals become a viable building block for the design of infrared sensors, device design needs to match with their actual operating conditions. While in the near IR and shortwave infrared room temperature operation have been demonstrated, longer wavelengths still require low…

Electrical integration of silicon nitride drum resonators

Srisaran Venkatachalam, Ronghua Zhou, Xin Zhou

Silicon nitride (SiN) strings and membranes, fabricated on pre-stressed thin film emerged as promising devices. Because they have nanogram effective mass and easily achieve in MHz range resonance frequency with high quality factor. Unfortunately, the insulant feature greatly limits implementations…
