Minimum Line Width of Surface Plasmon Resonance in Doped ZnO Nanocrystals

Christophe Delerue

The optical response of ZnO nanocrystals (NCs) doped with Al (Ga) impurities is calculated using a model that incorporates the effects of quantum confinement, dielectric mismatch, surface, and ionized impurity scattering. For dopant concentrations of a few percent, the NC polarizability is…

Advantages of ALD over evaporation deposition for high-K materials integration in high power capacitive RF MEMS

Guillaume Croizier, Paolo Martins, M. Le Bailiff, Raphaël Aubry, S. Bansropun, M. Fryziel, Nathalie Rolland, Afshin Ziaei

We report a study over a wide range of high-K dielectric materials (AlxOy, HfOx, TiOx.) deposited by different techniques (Evaporation, ALD, PEALD ... ) for high power RF applications. Main results show that ALD technique is matching the McPherson trend based on thermochemical prediction.…

An ultra-low power iterative clique-based neural network integrated in 65-nm CMOS

Paul Chollet, Benoit Larras, Cyril Lahuec, Fabrice Seguin, Matthieu Arzel

Clique-based neural networks are less complex than commonly used neural network models. They have a limited connectivity and are composed of simple functions. They are thus adapted to implement neuro-inspired computation units operating under severe energy constraints. This paper shows an ST 65-nm…

Antifouling biomimetic liquid-infused stainless steel: application to rairy industrial processing

Sawsen Zouaghi, Thierry Six, Séverine Bellayer, Sona Moradi, Savvas G. Hatzikiriakos, Thomas Dargent, V. Thomy, Yannick Coffinier, Christophe Andre, Guillaume Delaplace, Maude Jimenez

Fouling is a widespread and costly issue, faced by all food-processing industries. Particularly, in the dairy sector, where thermal treatments are mandatory to ensure product safety, heat-induced fouling represents up to 80% of the total production costs. Significant environmental impacts, due the…

Sputtered titanium carbide thick film for high areal energy on chip carbon-based micro-supercapacitors

Manon Létiche, Kevin Brousse, Arnaud Demortiere, Peihua Huang, Barbara Daffos, Sébastien Pinaud, Marc Respaud, Bruno Chaudret, Pascal Roussel, Lionel Buchaillot, Pierre-Louis Taberna, Patrice Simon, Christophe Lethien

The areal energy density of on-chip micro-supercapacitors should be improved in order to obtain autonomous smart miniaturized sensors. To reach this goal, high surface capacitance electrode (>100 mF cm−2) has to be produced while keeping low the footprint area. For carbide-derived carbon (CDC)…

Nanomaterials for transdermal drug delivery: beyond the state of the art of liposomal structures

Roxana Jijie, Alexandre Barras, Rabah Boukherroub, Sabine Szunerits

A wide range of biomedical materials have been proposed to meet the different needs for controlled oral or intravenous drug delivery. The advantages of oral delivery such as self-administration of a predetermined drug dose at defined time intervals makes it the most convenient means for the…

Non-destructive Evaluation of Containment Walls in Nuclear Power Plants

V. Garnier, C. Payan, M. Lott, Narintsoa Ranaivomanana, Jean-Paul Balayssac, Jérôme Verdier, E. Larose, Y. Zhang, J. Saliba, A. Boniface, Z. M. Sbartai, Bogdan Piwakowski, Charles Ciccarone, H. Hafid, J. M. Henault, F. Ouvrier Buffet

Two functions are regularly tested on containment walls in order to anticipate a possible accident. The first is mechanical to resist a possible internal over-pressure and the second is to prevent leakage. The AAPR reference accident is the rupture of a pipe in the primary circuit of a nuclear…
