Tunable physics through coordination chemistry: formation on oxide surface of Ti and Al chelates with 3-hydroxyflavone capable of electron injection and light emission

Getachew Solomon, Anton Landström, Silvia Rotta Loria, Eleonora Bolli, Alberto Mezzetti, Anna Facibeni, Sandro Cattarin, Alessio Mezzi, Stefano Protti, Saulius Kaciulis, Margherita Zavelani-Rossi, Isabella Concina

The optoelectronic features of 3-hydroxyflavone (3HF) self-assembled on the surface of an n-type semiconducting metal oxide (TiO2) and an insulator (Al2O3) are herein investigated. 3HF molecules use the coordinatively unsaturated metal ions present on the oxide surface to form metal complexes,…

Influence of the grafting process on the orientation and the reactivity of azide-terminated monolayers onto silica surface

Nisreen Al-Hajj, Yannick Mousli, Antoine Miche, Vincent Humblot, Julien Hunel, Karine Heuze, Thierry Buffeteau, Emilie Genin, Luc Vellutini

Click chemistry is widely used in materials and surface science for its high efficiency, ease of use and high yields. Azide-terminated SAMs have been prepared successfully by using three different deposition methods (postfunctionalization and direct grafting by immersion as well as spin coating).…

Bio-inspired calcium phosphate mineralization through enzymatic approach, Minéralisation de phosphate de calcium d'inspiration biologique par approche enzymatique

Jihye Lee

Biomineralization of calcium phosphate (CaP) is the process by which some organism builds hard mineralized tissues, such as bone, enamel and calcified cartilage. This process is regulated through various physicochemical factors and biochemical reactions, involving particularly matrix vesicles (MVs…, La biominéralisation du phosphate de calcium (CaP) est le processus par lequel un organisme construit des tissus minéralisés durs, tels que l'os, l'émail et le cartilage calcifié. Ce processus est régulé par divers facteurs physico-chimiques et réactions biochimiques, impliquant en…

Adsorption of bromothymol blue (BTB) dye using four zeolites as adsorbent

Imene Benchikh, Mohamed Serier, Franck Launay, Fatiha Djafri, Affaf Tabti

This study examined adsorption of anionic dye on four zeolitic materials incorporated (VS-1, CuZSM-5) and not incorporated into metals (S-1, ZSM-5). The adsorption of the bromothymol blue (BTB) dye on the four adsorbents was analysed using isotherm models Langmuir, Freundlich, and Temkin. Two…, U ovoj je studiji ispitivana adsorpcija anionskih bojila na četiri zeolitska materijala inkorporirana (VS-1, CuZSM-5) i neinkorporirana (S-1, ZSM-5) u metale. Adsorpcija indikatora bromtimol modro (BTB) na četiri adsorbenta analizirana je izotermnim modelima Langmuir, Freundlich i Temkin. Također…

Nanoparticles of Ni strongly embedded in porous silica : towards the design of efficient catalysts for lignin hydrogenolysis, Nanoparticules de Ni incorporées dans de la silice poreuse : vers la conception de catalyseurs efficaces pour l'hydrogénolyse de la lignine

Rita Raachini

Phenols may be obtained from lignin instead of petroleum. Here, improving lignin conversion by hydrogenolysis, while limiting side hydrogenation of produced phenols using nickel-based catalysts instead of noble metals, was our main concern. Porous materials made of highly dispersed nickel onto…, Les phénols peuvent être obtenus à partir de la lignine plutôt que du pétrole. Notre principale préoccupation était d’améliorer la conversion de la lignine par hydrogénolyse, tout en limitant l’hydrogénation des phénols produits en utilisant des catalyseurs à base de Ni au lieu de métaux nobles.…
