3D printed bioceramic for phage therapy against bone nosocomial infections

Franck Bouchart, Olivier Vidal, Jean-Marie Lacroix, Corentin Spriet, Shaan Chamary, Annie Brutel, Jean-Christophe Hornez

This study provides a new therapeutic response to postoperative joint and bone infections. Alone or in combination with antibiotics, phage therapy has many advantages, including accurate targeting of pathogenic bacteria. In addition, a decrease in harmful side effects can improve the healing…

Phase transformations and microstructural evolution in nanocrystalline Fe 71 B 23 Nb 6 alloy prepared by mechanical alloying

Mahmoud Chemingui, Chahida Mnasri, Christelle Nivot, Arnaud Tricoteaux, Yannick Lorgouilloux, Mohamed Dammak

Abstract A new nanocrystalline Fe 71 B 23 Nb 6 alloy powder was prepared by mechanical alloying. The phase transformation and morphological and microstructural properties of the as-prepared alloy were investigated by scanning electron microscopy, laser granulometry, and X-ray diffraction with…

Low voltage plasma jet with piezoelectric generator : preliminary evaluation of decontamination capabilities

Jordan Stekke, Claire Tendero, Pascal Tierce, Christian Courtois, Gaetan Rauwel, Juslan Lo, Philippe Guillot, François Pigache

This paper deals with the proof of concept and the preliminary evaluation of decontamination performances obtained with a plasma jet generated by a piezoelectric transformer. This low voltage supply solution (<10V) is investigated as a plasma jet device, compact and safe solution for the…

Ultra-fast laser surface texturing of β-tricalcium phosphate (β-TCP) ceramics for bone-tissue engineering applications

Albena Daskalova, Marie Lasgorceix, Irina Bliznakova, Liliya Angelova, Stéphane Hocquet, Anne Leriche, Anton Trifonov, Ivan Buchvarov

Abstract β-tricalcium phosphate (β-TCP) has provoked particular attention as graft for bone regeneration applications due to its excellent biocompatibility and biodegradability. In this work, we investigated the interaction of femtosecond laser radiation with β-TCP pellets by varying the output…

Influence of microwave sintering on electrical properties of BCTZ lead free piezoelectric ceramics

Kelly Orlik, Yannick Lorgouilloux, Pascal Marchet, Anthony Thuault, Mohamed Rguiti, Christian Courtois, Florian Jean

Barium titanate doped with calcium and zirconium (BCTZ) could be used at low temperature to replace lead based piezoelectric ceramics (PZT). The classical way to obtain BCTZ is the solid-state route coupled with conventional sintering, but this step is time-consuming. To reduce the duration of this…

Collision Times of Random Walks and Applications to the Brownian Web

David Coupier, Kumarjit Saha, Anish Sarkar, Viet Chi Tran

Convergence of directed forests, spanning on random subsets of lattices or on point processes, towards the Brownian web has made the subject of an abundant literature, a large part of which relies on a criterion proposed by Fontes, Isopi, Newman and Ravishankar (2004). One of their convergence…

Characterization and extensive study of cubic and quintic algebraic trigonometric planar PH curves, Caractérisation et étude approfondie des courbes planes algébriques-trigonométriques à hodographe pythagorien

Isabelle Cattiaux-Huillard, Laura Saini

This paper deals with Pythagorean hodograph curves of the spaces of algebraic trigonometric functions and trigonometric polynomials, span {1, t, {cos (kt) , sin (kt)}k=1^m and span {1, {cos (kt) , sin (kt)}k=1^m , respectively. First, we propose a general characterization of planar PH curves in…

Sintering of BaTiO3 powder/sol composite thick films and their dielectric and piezoelectric properties

Jean-François Trelcat, Natanaël Basile, Maurice Gonon, Mohamed Rguiti, Christian Courtois, Anne Leriche

In this work, barium titanate thick films are produced at low-temperature using a modified sol–gel/ceramic powder technology named the composite route. In this process, a commercial BaTiO3 powder, doped or not by Li2O as sintering aid, is mixed with a stabilized titanium (IV) isopropoxide/barium…

Weighted-$L^2$ polynomial approximation in $\mathbb {C}$

Séverine Biard, John Erik Fornæss, Jujie Wu

We study the density of polynomials in H2(Ω, e−φ), the space of square integrable holomorphic functions in a bounded domain Ω in C, where φ is a subharmonic function. In particular, we prove that the density holds in Carath´eodory domains for any subharmonic function φ in a neighborhood of Ω. In…
