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,…

Fate of L-DOPA in the Presence of Inorganic Matrices: Vectorization or Composite Material Formation?

Maguy Jaber, Meryem Bouchoucha, L. Delmotte, Christophe Méthivier, Jean-Marc Krafft, Jean-François Lambert

Novel bionanocomposite materials were successfully prepared using 2:1 phyllosilicates and an amino acid, L-DOPA. A systematic study of DOPA interactions with these smectites and with a nonporous amorphous silica (Aerosil) used for comparison was undertaken by combining macroscopic information,…

Synthetic Manipulation on the Microstructure of Co Species‐Containing Mesoporous Silica Matrices: Impact on the Efficiency for Fischer‐Tropsch and Water Oxidation Reactions

Laura Altenschmidt, Amélie Bordage, Giulia Fornasieri, Patricia Beaunier, Eric Rivière, Eva Pugliese, Ally Aukauloo, Anne Bleuzen

Mesoporous silica containing Co species is effective in a wide variety of catalytic processes. Nevertheless, the catalytic efficiency of such materials strongly depends on their preparation. Two model compounds made of SBA-15 type ordered mesoporous silica monoliths containing Co(II) nitrate salt…

To be born is not enough: the key role of innovative start-ups

Alessandra Colombelli, Jackie Krafft, Marco Vivarelli

This paper investigates the reasons why entry per se is not necessarily good and the evidence showing that innovative start-ups survive longer than their non-innovative counterparts. In this framework, our own empirical analysis shows that greater survival is achieved when start-ups engage…

Interfacial Coordination Chemistry for Catalyst Preparation

Eric Marceau, Laurent Bonneviot, Stanislaw Dzwigaj, Jean-François Lambert, Catherine Louis, Xavier Carrier

The concept of interfacial coordination chemistry was one of the innovation for which Michel Che became internationally known during his tenure as full professor at the Université Pierre et Marie Curie. Isolated metal ions on oxide surfaces behave like coordination compounds to which the surface…

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…
