Supramolecular Self‐Assembly and Organization of Collagen at Solid/Liquid Interface: Effect of Spheroid‐ and Rod‐Shaped TiO 2 Nanocrystals

Mathieu Beauvais, Thomas Degabriel, Nesrine Aissaoui, Vincent Dupres, Elodie Colaço, Karim El Kirat, Rute F Domingos, Dalil Brouri, Claire‐marie Pradier, Jolanda Spadavecchia, Jessem Landoulsi

The adsorption behavior of collagen on solid surfaces is a process that determines the role of this protein to mediate cell–material interaction. Herein, the mechanism of self‐assembly and organization of collagen on a model substrate is investigated in the presence of TiO2 nanoparticles. In…

Prebiotic Organization of Biomolecules on Mineral Surfaces, Organisation prébiotique de biomolécules sur des surfaces minérales

Hagop Abadian

This thesis reports on the adsorption of two amino acids (AA) with different properties, Leucine and Glutamic acid, on the amorphous silica surface. It exemplifies a general approach to hybrid systems that combines experimental information and molecular modeling in order to characterize at the…, Cette thèse porte sur l'adsorption de deux acides aminés aux propriétés différentes, la leucine et l'acide glutamique, sur la surface de la silice amorphe. Une combinaison d'informations expérimentales et de modélisation moléculaire a été entreprise afin de caractériser au niveau…

Synthesis of RNA nucleotides in plausible prebiotic conditions from ab initio computer simulations

Andrea Pérez-Villa, Antonino Marco Saitta, Thomas Georgelin, Jean-François Lambert, François Guyot, Marie-Christine Maurel, Fabio Pietrucci

Understanding the mechanism of spontaneous formation of ribonucleotides under realistic prebiotic conditions is a key open issue of origins-of-life research. In cells, de novo and salvage nucleotide enzymatic synthesis combines 5-phospho-α-d-ribose-1-diphosphate (α-PRPP) and nucleobases.…

Biomineralization Patterns of Intracellular Carbonatogenesis in Cyanobacteria: Molecular Hypotheses

Jinhua Li, Isabel Margaret-Oliver, Nithavong Cam, Thomas Boudier, Marine Blondeau, Eric Leroy, Julie Cosmidis, Feriel Skouri-Panet, Jean-Michel Guigner, Céline Férard, Melanie Poinsot, David Moreira, Purificacion Lopez-Garcia, Corinne Cassier-Chauvat, Franck Chauvat, Karim Benzerara

The recent discovery of intracellular carbonatogenesis in several cyanobacteria species has challenged the traditional view that this process was extracellular and not controlled. However, a detailed analysis of the size distribution, chemical composition and 3-D-arrangement of carbonates in these…

Insight into the Nature of the ZnO x Promoter during Methanol Synthesis

Remco Dalebout, Laura Barberis, Giorgio Totarella, Savannah Turner, Camille La Fontaine, Frank de Groot, Xavier Carrier, Ad van der Eerden, Florian Meirer, Petra de Jongh

Despite the great commercial relevance of zinc-promoted copper catalysts for methanol synthesis, the nature of the Cu–ZnOx synergy and the nature of the active Zn-based promoter species under industrially relevant conditions are still a topic of vivid debate. Detailed characterization of the…
