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...

Near-infrared light activatable hydrogels for metformin delivery

Li Chengnan, Quentin Pagneux, Anna Voronova, Alexandre Barras, Amar Abderrahmani, Valérie Plaisance, Valérie Pawlowski, Nathalie Hennuyer, Bart Staels, Lea Rosselle, Nadia Skandrani, Musen Li, Rabah Boukherroub, Sabine Szunerits

Drug loaded hydrogels have proven to be versatile controlled-release systems. We report here on heat active hydrogel formation by mixing graphene oxide (GO) or carboxyl enriched reduced graphene oxide (rGO-COOH) with metformin hydrochloride, an insulin sensitizer drug currently used as the first...

Chapter 6 - One-dimensional magnonic crystals

L. Dobrzynski, Abdellatif Akjouj, Housni Al-Wahsh, Bahram Djafari-Rouhani

This chapter presents examples of bulk and surface magnons of one-dimensional magnonic crystals, called also superlattices. The such man-made crystals considered here are grown out of semiinfinite stacks of two and also three different ferromagnetic slabs. Each slab is modeled by a simple cubic...

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...

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...

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...

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...

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...

Thermal Stability of Oleate‐Stabilized Gd2O2S Nanoplates in Inert and Oxidizing Atmospheres

Clément Larquet, D. Hourlier, Anh-Minh Nguyen, Almudena Torres-Pardo, Andrea Gauzzi, Clément Sanchez, Sophie Carenco

Capping ligands play an important role in the chemistry of nanoparticles synthesized with organic surfactants. This is relevant to a number of device applications where heating may cause major modifications of crystalline nanoparticles including amorphization, surface rearrangements or sintering....
