Ethylene production from diluted bioethanol solutions

Ilenia Rossetti, Matteo Compagnoni, Giorgia de Guido, Laura A. Pellegrini, Gianguido Ramis, Stanislaw Dzwigaj

Ethylene production by ethanol dehydration has been investigated over a set of zeolites with BEA structure in acidic form (HAlBEA). The effect on Ni addition (up to 0.03 g/g (3 mass%)) is explored as a means to improve ethylene selectivity limiting the formation of heavier byproducts. The reaction…

Chiral self-assemblies of amino-acid molecules: D- and L-methionine on Au(111) surface

Ahmed Naitabdi, Vincent Humblot

Spontaneous self-assembly into chiral well-ordered two-dimensional molecular film at room temperature has been evidenced using the scanning tunneling microscopy for the growth of two enantiomerically pure L- and D-methionine on Au(111) surface. From the x-ray photoelectron spectroscopy measurements…

Low-energy electron induced resonant loss of aromaticity: consequences on cross-linking in terphenylthiol SAMs

L. Amiaud, J. Houplin, M. Bourdier, V. Humblot, R. Azria, C.-M. Pradier, A. Lafosse

Aromatic self-assembled monolayers (SAMs) can be used as negative tone electron resists in functional surface lithographic fabrication. A dense and resistant molecular network is obtained under electron irradiation through the formation of a cross-linked network. The elementary processes and…

Investigation of the interface in silica-encapsulated liposomes by combining solid state NMR and first principles calculations.

Nicolas Folliet, Claire Roiland, Sylvie Bégu, Anne Aubert, Tzonka Mineva, Annick Goursot, Kaliaperumal Selvaraj, Luminita Duma, Frederik Tielens, Francesco Mauri, Guillaume Laurent, Christian Bonhomme, Christel Gervais, Florence Babonneau, Thierry Azaïs

In the context of nanomedicine, liposils (liposomes and silica) have a strong potential for drug storage and release schemes: such materials combine the intrinsic properties of liposome (encapsulation) and silica (increased rigidity, protective coating, pH degradability). In this work, an original…

Structural studies of adsorbed protein (betalactoglobulin) on natural clay (montmorillonite)

Ali Assifaoui, Lucie Huault, Cyrielle Maissiat, Chloé Roullier-Gall, Philippe Jeandet, Jerôme Hirschinger, Jesus Raya, Maguy Jaber, Jean-François Lambert, Philippe Cayot, Régis Gougeon, Camille Loupiac

In this work, the adsorption of a small globular protein (betalactoglobulin, BLG), on a natural montmorillonite clay (Mt) was investigated in acidic buffer (pH = 3). The combination of different characterization techniques such as zetametry, X-ray diffraction, transmission electronic microscopy,…

A DNA biosensor based on peptide nucleic acids on gold surfaces

Eva Mateo-Marti, C. Briones, Claire-Marie Pradier, Jose A. Martin-Gago

We present a DNA biosensor based on self assembled monolayers (SAMs) of thiol-derivatized Peptide nucleic acid (PNA) chains adsorbed on gold surfaces for recognizing complementary ssDNA. PNA molecules tend to realign their molecular axes parallel to the surface normal and form SAMs on gold surfaces…
