Characterisation of early HepG2/3a cell response to a microfluidic culture in liver biochips using multi-parametric real time image processing

Marie Naudot, Patrick Paullier, Thomas Dargent, Vincent Senez, Zaher Kharboutly, Isabelle Claude, Eric Leclerc

We developed an image processing protocol to perform time lapse fluorescent analysis in microfluidic biochips. Using three probes to follow three parameters: the number of cell nucleus, the mitochondrial activity and the cell death, we have investigated the behaviour of HepG2/C3a under microfluidic…

Ion-beam effect on functional properties of La2Ti2O7 piezoelectric thin films and nanoislands

A. Ferri, S. Saitzek, Z. Shao, A. Bayart, G. Declercq, Jean Costecalde, Denis Remiens, D. Deresmes, David Troadec, Rachel Desfeux

Low-dimensional material can display unique physical phenomena allowing an interesting way for the development of new technologies. In addition, owing the environmental requirements about electronic devices (ferroelectric memories, M/NEMS...), new lead-free piezoelectrics need to be created. In…

The resonance/thickness prediction of an ultra-thin layer by the low-frequency ultrasound

Gui-Jin Yao, Wei-Jiang Xu, Ke-Xie Wang

A prediction method of the thickness, resonant space and frequency for the two cases of an ultra-thin layer and the narrow-band frequency spectra has been developed without the appearance of the resonance/anti-resonance. Using the characteristic of straight line and the period of π of the layer…

Electrical and chemical studies on Al2O3 passivation activation process

Matthieu Pawlik, Jean-Pierre Vilcot, Mathieu Halbwax, D. Aureau, A. Etcheberry, A. Slaoui, T. Schutz-Kuchly, R. Cabal

Passivation process is a key feature to improve the efficiency of silicon solar cells. So far, a 20nm-thick layer of Al2O3 grown by Plasma Enhanced Atomic Layer Deposition (PE-ALD) followed by a 450°C anneal during 15 to 30 min gives the best results in surface carrier recombination velocities on p…

Polymer based flapping-wing robotic insect : progress in design, fabrication and characterization

Alexandre Bontemps, Thomas Vanneste, Caroline Soyer, Jean-Bernard Paquet, Sébastien Grondel, Eric Cattan

In the last decade, many researchers pursued the development of tiny flying robots inspired by natural flyers destined for the exploration of confined spaces, for example. Within this context, our main objective is to devise a flying robot bioinspired from insect in terms of size and wing…

A Novel Dog-Bone Oscillating AFM Probe with Thermal Actuation and Piezoresistive Detection

Zhuang Xiong, Estelle Mairiaux, Benjamin Walter, Marc Faucher, Lionel Buchaillot, Bernard Legrand

In order to effectively increase the resonance frequency and the quality factor of atomic force microscope (AFM) probes, a novel oscillating probe based on a dog-bone shaped MEMS resonator was conceived, designed, fabricated and evaluated. The novel probe with 400 μm in length, 100 μm in width and…

Key parameters of silicon micropillar arrays for solar cell performance optimization

Di Zhou, Yan Pennec, Bahram Djafari-Rouhani, Odile Cristini, Tao Xu, Yannick Lambert, Didier Stiévenard

Surface nanostructuration is an important challenge for the optimization of light trapping design in solar cell. We present simulations of the optical properties and efficiency of nanostructured (micropilars-MPs- or nanocones-NCs-) silicon based solar cells as well as measurements of their optical…

Source localisation in a reverberant plate using average coda properties and early signal strength

Hossep Achdjian, Emmanuel Moulin, Farouk Benmeddour, Jamal Assaad, Lynda Chehami

A statistical reverberation model based on the average distribution of wave packets propagating in a finite plate is described and it is shown that by fitting experimental data to theoretical expressions, either structural or source-related features can be extracted with very few sensors. An…
