Layer-by-Layer Assembly of Nanosized Membrane Fractions for the Assessment of Cytochrome P450 Xenobiotic Metabolism

Paul Quantin, Elodie Colaço, Karim El Kirat, Christophe Egles, Hervé Ficheux, Jessem Landoulsi

Herein, we report the use of sequential layer-by-layer (LbL) assembly to design nanostructured films made of recombinant bacterial membrane fractions (MF), which overexpress cytochrome P450 (CYP) and cytochrome P450 reductase. The ability to incorporate MF in LbL multilayered films is demonstrated…

HgTe Nanocrystal Inks for Extended Short‐Wave Infrared Detection

Bertille Martinez, Julien Ramade, Clément Livache, Nicolas Goubet, Audrey Chu, Charlie Gréboval, Junling Qu, William L Watkins, Loic Becerra, Erwan Dandeu, Jean Louis Fave, Christophe Méthivier, Emmanuelle Lacaze, Emmanuel Lhuillier

Short‐wave infrared (IR) detection is currently driven by InGaAs technology which has limited the perspective of cost effectiveness and consequently slows the development of IR sensors. Since organic electronics are ineffective in this wavelength range, an alternative to conductive polymers is the…

Contributions of photochemistry to bio-based antibacterial polymer materials

Davy-Louis Versace, Louise Breloy, Estelle Palierse, Thibaud Coradin

Surgical site infections constitute a major health concern that may be addressed by conferring antibacterial properties to surgical tools and medical devices via functional coatings. Bio-sourced polymers are particularly well-suited to prepare such coatings as they are usually safe and can exhibit…

Development of a hybrid coating associating biomimetic hydroxyapatite and natural antibiotics with antibacterial properties, Développement d’un revêtement hybride aux propriétés antibactériennes associant hydroxyapatite biomimétique et antibiotiques naturels

Estelle Palierse

This thesis aims to develop a hybrid coating based on biomimetic hydroxyapatite and natural antibacterial molecules, with the goal to add antibacterial properties and enhance the osseointegration of titanium (Ti6Al4V) implants. Four natural biologically active molecules (BAMs) were tested,…, Cette thèse porte sur l’élaboration de revêtements de surface hybrides composés d’hydroxyapatite biomimétique et de molécules antibactériennes naturelles, dans le but d’ajouter des propriétés antibactériennes et d’améliorer l’ostéointégration d’implants en titane (Ti6Al4V). Quatre molécules…

In situ surface imaging: High temperature environmental SEM study of the surface changes during heat treatment of an Al Si coated boron steel

M. Barreau, C. Méthivier, T. Sturel, C. Allely, P. Drillet, S. Cremel, R. Grigorieva, B. Nabi, Renaud Podor, J. Lautru, V. Humblot, J. Landoulsi, X. Carrier

Al-Si coated boron steels have been of interest for many years because of their superior mechanical properties and their excellent oxidation resistance. These high strength steels are particularly used in hot stamping processes during which the Al-Si coating undergoes multiple microstructural…

Anchoring of Pt(II) Pyridyl Complex to Mesoporous Silica Materials: Enhanced Photoluminescence Emission at Room Temperature and Photooxidation Activity using Molecular Oxygen

Kohsuke Mori, Kentaro Watanabe, Masayoshi Kawashima, Michel Che, Hiromi Yamashita

Chloro(2,2':6',2''-terpyridine)platinum(II) ([Pt(tpy)Cl]Cl) complex was successfully anchored to a series of (3-aminopropyl)trimethoxysilane-modified mesoporous silica materials (MCM-41, SBA-15, and MCM-48). Pt LIII-edge x-ray absorption fine structure (XAFS) measurements reveal…

Different Kinds of Tetrahedral V Species in Vanadium-Containing Zeolites Evidenced by Diffuse Reflectance UV-vis, Raman, and Periodic Density Functional Theory

Anna E. Lewandowska, Miguel A. Banares, Frederik Tielens, Michel Che, Stanislaw Dzwigaj

The combined use of DR-UV-vis and Raman spectroscopies allows one to evidence three kinds of tetrahedral V-V with different structure in V(x)SiBEA zeolite. In all cases, vanadium species possess distorted tetrahedral configuration. At very low vanadium content (0.05 wt %), the majority of…

In Situ Generation of Active Pd Nanoparticles within a Macroreticular Acidic Resin: Efficient Catalyst for the Direct Synthesis of Hydrogen Peroxide

Kohsuke Mori, Akihiro Hanafusa, Michel Che, Hiromi Yamashita

An acidic resin bearing SO3H functional groups within its reticular structure acts as an efficient support for the in situ formation of highly active Pd nanoparticles (NPs) responsible for the direct synthesis of hydrogen peroxide from H2 and O2. Characterization by means of X-ray absorption fine…
