Physical and electrical characterization of bubble free transferred single crystal graphene

Soukaina Ben Salk, Reetu Raj Pandey, Phi Hq Pham, Di Zhou, Dominique Vignaud, Emiliano Pallecchi, Peter Burke, Henri Happy

Monocrystalline graphene is desirable for practical applications since the large-scale polycrystalline graphene grown by chemical vapor deposition is limited in terms of performance. The transfer of graphene film from the metallic growth substrate to a host substrate, which is generally required…

Contribution of alginate nanoparticles to the multifunction of antimicrobial peptides, example of the class IIb bacteriocin Enterocin DD14, Apport des Nanoparticules d'alginate à la multifonction des peptides antimicrobiens, exemple de la bactériocine de classe IIb Entérocine DD14

Hassan Zgheib

In this PhD project, we used alginate nanoparticles as carriers of a leaderless two-peptide bacteriocin, the enterocin14designed EntDD14. This bacteriocin, previously isolated from Enterococcus faecalis 14 strain, was characterized for its potent anti-bacterial activity against a set of Gram-…, Dans ce projet de thèse, nous avons évalué l’apport des nanoparticules d’alginate sur la multifonction des bactériocines, en particulier l’entérocine DD14 (EntDD14). Cette bactériocine à deux peptides sans séquence leader, appartenant donc à la calsse IIb, a été caractérisée pour son activité…

Unusual swelling of acrylate based crosslinked polymer networks in linear primary alcohols: Experimental and modeling aspects

Sofiane Bedjaoui, Lamia Bedjaoui, Mohammed-El-Amine Benbekeda, Frédéric Dubois, Dounya Merah, Philippe Supiot, Corinne Foissac, Ulrich Maschke

The present investigation focuses on analysis of swelling behavior of systems composed of linear primary alcohols and photo-chemically crosslinked poly (butyl prop-2-enoate) (PABu). For this purpose, reactive blends composed of monofunctional (n-ABu) and difunctional (1-prop-2-enoyloxyhexyl prop-2-…

Filtres acousto-optiques accordables à sélection de polarisation pour l'imagerie hyperspectrale, Acousto-optic tunable filter with polarization selection for hyperspectral imaging

Justine Champagne

L’imagerie hyperspectrale et de polarimétrie est un domaine en plein essor qui présente de nombreuses applications. Ce contexte pousse à améliorer sans cesse les filtres, notamment en termes de résolution spectrale. Il est utile par exemple d’augmenter le nombre de bandes spectrales et leurs…, Hyperspectral and polarimetric imaging shows numerous applications and is rapidly developing. This context encourages continuous improvement of filters, particularly for the spectral resolution. For instance, it can be useful to increase the number of spectral bands and reduce the spectral…

An Ultra-low-Power Integrated Heartbeat Detector for Wearable Sensors

Antoine Gautier, Marine Dael, Robin Benarrouch, Benoit Larras, Antoine Frappé

To optimize energy consumption in wearable sensor networks, an efficient scheme is to set the sensors in sleep mode and wake them up to engage communication. However, synchronicity between the sensors needs to be assured by always-on local oscillators. This work proposes a different topology that…
