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...

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...

Effect of incubation duration, growth temperature, and abiotic surface type on cell surface properties, adhesion and pathogenicity of biofilm-detached Staphylococcus aureus cells

Oussama Khelissa, Charafeddine Jama, Marwan Abdallah, Rabah Boukherroub, Christine Faille, Nour-Eddine Chihib

The goal of this study was to investigate the effect of growth conditions such as the temperature (20, 30 and 37 °C), incubation duration (24 and 48 h) and surface type (stainless steel and polycarbonate) on the cell surface physicochemical properties and adhesion to abiotic surfaces of biofilm-...

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)...

Universal behavior of electron g -factors in semiconductor nanostructures

Athmane Tadjine, Yann-Michel Niquet, Christophe Delerue

We combine analytic developments and numerical tight-binding calculations to study the evolution of the electron g-factors in homogeneous nanostructures of III-V and II-VI semiconductors. We demonstrate that the g-factor can be always written as a sum of bulk and surface terms. The bulk term, the...

Acoustic Energy Transfer by Friction Induced Vibrations

Giovanna Lacerra, F. Massi, Eric Chatelet, Emmanuel Moulin

Friction-induced vibrations are often investigated for their unwanted effects, such as surface wear and dynamic instabilities. This article focuses on the exploitation of friction-induced vibrations to transfer the energy between different acoustic fields by an interface under frictional contact....

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...

Validation expérimentale d'un couplage de deux modes vibratoires pour la reproduction de la cinématique d'ailes d'insecte et la production de portance

Damien Faux, Olivier Thomas, Sébastien Grondel, Eric Cattan

Ce travail se base sur le concept original de l’utilisation d’un couplage de deux modes vibratoires pour la reproduction de la cinématique d’une aile d’insecte et la génération de portance. La problématique étant de déterminer la géométrie et les propriétés élastiques des ailes artificielles telles...

Dielectric properties characterization of saline solutions by near-field microwave microscopy

S. Gu, Tianjun Lin, T. Lasri

Saline solutions are of a great interest when characterizations of biological fluids are targeted. In this work a near-field microwave microscope is proposed for the characterization of liquids. An interferometric technique is suggested to enhance measurement sensitivity and accuracy. The...

Estimation conjointe du canal et de l'offset de fréquence pour l'UFMC

Eric Pierre Simon, Florian Kaltenberger, Hussein Hijazi

– La modulation UFMC (Universal-filtered multi-carrier) est une nouvelle modulation multiporteuses incluant des filtres pour les sous-bandes, qui vise à remplacer la modulation OFDM (Orthogonal Frequency Division Multiplexing). L'objectif de l'UFMC est de relâcher les contraintes de...
