Influence des paramètres des procédés de fabrication additive métallique sur le comportement en corrosion de l’acier inoxydable 316L, Influence of metal additive manufacturing parameters on the corrosion behavior of 316L stainless steel

Alexis Fouchereau

Ces dernières années, la fabrication additive est devenue une source importante de créativité pour le développement de matériaux complexes qui défient l'utilisation de leurs homologues traditionnels. En fusion laser sur lit de poudre (L-PBF), les propriétés des matériaux sont largement…, In recent years, additive manufacturing has become a significant source of creativity for the development of complex materials which challenge the use of their traditional counterparts. In laser powder bed fusion (L-PBF), the material properties are widely influenced by the process parameters and…

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,…

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…

Direct AFM force mapping of surface nanoscale organization and protein adsorption on an aluminum substrate

Jessem Landoulsi, V. Dupres

We investigate the nanoscale organization of a superficially hydroxylated Al substrate and its effect on subsequent protein adsorption using atomic force microscopy (AFM). For this purpose we used a mode which allows a direct mapping of a variety of surface properties (adhesion, elasticity,…

Erratum to: Surface functionalization by covalent immobilization of an innovative carvacrol derivative to avoid fungal biofilm formation

Aïcha Gharbi, Thibaut Legigan, Vincent Humblot, Sébastien Papot, Christine Imbert, Jean-Marc Berjeaud

Carvacrol, an aromatic terpenic compound, known to be antimicrobial was grafted onto gold surfaces via two strategies based on newly-synthesized cross-linkers involving either an ester bond which can be cleaved by microbial esterases, or a covalent ether link. Surface functionalizations were…

Development of novel anti-Kv 11.1 antibody-conjugated PEG-TiO2 nanoparticles for targeting pancreatic ductal adenocarcinoma cells

Angelica Sette, Jolanda Spadavecchia, Jessem Landoulsi, Sandra Casale, Bernard Haye, Olivia Crociani, Annarosa Arcangeli

Titanium dioxide (TiO2) has been widely used in many nanotechnology areas including nanomedicine, where it could be proposed for the photodynamic and sonodynamic cancer therapies. However, TiO2 nanoformulations have been shown to be toxic for living cells. In this article, we report the development…

Photocatalytic Hydrogen Evolution Using Ni–Pd/TiO 2 : Correlation of Light Absorption, Charge-Carrier Dynamics, and Quantum Efficiency

Ana Luna, Diana Dragoe, Kunlei Wang, Patricia Beaunier, Ewa Kowalska, Bunsho Ohtani, Daniel Bahena Uribe, Miguel A. Valenzuela, Hynd Remita, Christophe Colbeau-Justin

TiO2 surface modification with bimetallic nano particles (NPs) has demonstrated to be a strategy to enhance the hydrogen generation via photocatalysis and to minimize the use of expensive noble metals. A better understanding of the role of bimetallic NPs is of crucial importance to design efficient…

Au, Cu and bimetallic Au–Cu nanoparticles were synthesized on the surface of commercial TiO2 compounds (P25) by reduction of the metal precursors with tetrakis(hydroxymethyl) phosphonium chloride (THPC) (0.5% in weight). The alloyed structure of Au–Cu NPs was confirmed by HAADF-STEM, EDS, HRTEM and…

On the promoting effect of Au on CO oxidation kinetics of Au-Pt bimetallic nanoparticles supported on SiO2: An electronic effect?

Rachel P. Doherty, Jean-Marc Krafft, Christophe Méthivier, Sandra Casale, Hynd Remita, Catherine Louis, Cyril Thomas

Bimetallic AuPt nanoparticles prepared by radiolysis with Au/Pt atomic ratios of 1.2 and 1.8 were deposited onto silica and calcined to remove the stabilizing polymers. During this sequence, they lose their core-shell structure and restructure as alloys. FTIR and XPS provide evidence for further…
