Highly confined radial contour modes in phononic crystal plate based on pillars with cap layers

Mohammed Moutaouekkil, Abdelkrim Talbi, El Houssaine El Boudouti, Omar Elmazria, Bahram Djafari-Rouhani, Philippe Pernod, Olivier Bou Matar

We investigate highly confined and isolated surface modes in a phononic crystal plate based on pillars with cap layers. The structure is made of a thin membrane supporting periodic pillars each composed of one cylinder surmounted by a disk shaped cap layer. An optimal choice of the geometrical...

Blocking bacterial entry at the adhesion step reveals dynamic recruitment of membrane and cytosolic probes

Yann Ciczora, Sébastien Janel, Magali Soyer, Michka Popoff, Elisabeth Werkmeister, Frank Lafont

Background: Bacterial invasion covers two steps: adhesion and entry per se. The cell signalling response is triggered upon pathogen interaction at the cell surface. This response continues when the pathogen is internalised. It is likely that these two steps activate different molecular machineries...

Medical video coding based on 2nd-generation wavelets: performance evaluation

Merzak Ferroukhi, Abdeldjalil Ouahabi, Mokhtar Attari, Yassine Habchi, Abdelmalik Taleb-Ahmed

The operations of digitization, transmission and storage of medical data, particularly images, require increasingly effective encoding methods not only in terms of compression ratio and flow of information but also in terms of visual quality. At first, there was DCT (discrete cosine transform) then...

Elastic wave propagation in smooth and wrinkled stratified polymer films

M Hesami, A. Gueddida, N Gomopoulos, H S Dehsari, K Asadi, S Rudykh, H-J Butt, Bahram Djafari-Rouhani, G Fytas

Periodic materials with sub-micrometer characteristic length scale can provide means for control of propagation of hypersonic phonons. In addition to propagation stopbands for the acoustic phonons, distinct dispersive modes can reveal specific thermal and mechanical behavior under confinement. Here...

On a generic theory of the organic electrochemical transistor dynamics

Vasileios Athanasiou, Sébastien Pecqueur, Dominique Vuillaume, Zoran Konkoli

In the recent years, the organic electrochemical transistors (OECT) have attracted considerable attention for biosensing applications due to the biocompatibility of their materials and their low operating voltages. Upon exposure to an electrolyte, the drain current becomes ion-dependent. This can...

Exploring Light-Sensitive Nanocarriers for Simultaneous Triggered Antibiotic Release and Disruption of Biofilms Upon Generation of Laser-Induced Vapor Nanobubbles

Eline Teirlinck, Alexandre Barras, Jing Liu, Juan Andrés A Fraire, Tatu Lajunen, Ranhua Xiong, Katrien Forier, Chengnan Li, Arto Urtti, Rabah Boukherroub, Sabine Szunerits, Stefaan C de Smedt, Tom Coenye, Kevin Braeckmans

Impaired penetration of antibiotics through bacterial biofilms is one of the reasons for failure of antimicrobial therapy. Hindered drug diffusion is caused on the one hand by interactions with the sticky biofilm matrix and on the other hand by the fact that bacterial cells are organized in densely...

Ferroelectric multiple-valued logic units

Igor A. Luk'Yanchuk, Elena Zaitseva, Vitaly Levashenko, Miroslav Kvassay, Svitlana Kondovych, Yuri Tikhonov, Laurent Baudry, Anna Razumnaya

Employing many-valued logic (MVL) data processing allows to dramatically increase the performance of computing circuits. Here we propose to employ ferroelectrics for the material implementation of MVL units basing on their ability to pin the polarization as a sequence of multi-stable states. Two...

Massless Dirac fermions in III-V semiconductor quantum wells

Sergey S. Krishtopenko, W. Desrat, K. Spirin, C. Consejo, S. Ruffenach, F. Gonzalez-Posada, Benoit Jouault, W. Knap, K. Maremyanin, V. Gavrilenko, G. Boissier, J. Torres, M. Zaknoune, E. Tournié, F. Teppe

We report on the clear evidence of massless Dirac fermions in two-dimensional system based on III-V semiconductors. Using a gated Hall bar made on a three-layer InAs/GaSb/InAs quantum well, we restore the Landau level fan chart by magnetotransport and unequivocally demonstrate a gapless state in...
