Inorganic Phosphate and Nucleotides on Silica Surface: Condensation, Dismutation, and Phosphorylation

Thomas Georgelin, Maguy Jaber, Thomas Onfroy, Aaron-Albert Hargrove, France Costa-Torro, Jean-François Lambert

We explore the reactivity of inorganic monophosphate ions (Pi) and 5′-adenosine monophosphate (AMP), adsorbed onto amorphous silica separately or together. This question has relevance for prebiotic chemistry scenarios and, more generally, for biomedical applications involving biomolecule adsorption…

A New Nanocomposite: L-DOPA/Laponite

Maguy Jaber, Jean-Francois Lambert

A simple procedure is reported to obtain original nanocomposite materials combining the smectite Laponite and melanin-like polymers. Aq. polymn. of L-DOPA is considerably accelerated in the presence of suspended Laponite particles, and its mechanism is significantly modified with respect to…

BSA adsorption on aliphatic and aromatic acid SAMs: Investigating the effect of residual surface charge and sublayer nature

Anne Vallée, Vincent Humblot, Rana Al Housseiny, Souhir Boujday, Claire-Marie Pradier

n this work, the influence of surface charge and layer rigidity on Bovin Serum Albumin (BSA) adsorption has been investigated. To this aim, Self Assembled Monolayers (SAMs) bearing terminal COOH or COO− groups were built on gold surfaces. The rigidity of the acid terminated SAMs was modified using…

Hydrogen and syngas production by methane dry reforming on SBA-15 supported nickel catalysts: On the effect of promotion by Ce0.75Zr0.25O2 mixed oxide

Abdulkader Albarazi, Patricia Beaunier, Patrick da Costa

In this work, the effects of doping Ni-based SBA-15 catalysts with Ceria-Zirconia mixed oxide (CZ) on the activity and stability of these catalysts during syngas production by methane dry reforming (MDR) were investigated and compared with the activity and stability of unmodified Ni/SBA-15. The…

Surface chemistry and surface reactivity of fibrous amphiboles that are not regulated as asbestos

M. Fantauzzi, M. Pacella, J. Fournier, A. Gianfagna, G. B. Andreozzi, A. Rossi

Three fibrous amphiboles that are not regulated as asbestos--two from Biancavilla (Sicily, Italy) and one from Libby (MT, USA)--were studied in order to establish relationships between surface chemistry and surface reactivity. The three fibrous samples, plus one prismatic fluoro-edenite from…

Quantitative Investigation of MgO Bronsted Basicity: DFT, IR, and Calorimetry Study of Methanol Adsorption

Hugo Petitjean, Konstantin Tarasov, Francoise Delbecq, Philippe Sautet, Jean-Marc Krafft, Philippe Bazin, Maria Cristina Paganini, Elio Giamello, Michel Che, Helene Lauron-Pernot, Guylene Costentin

The adsorption geometries, energies, and vibrational frequencies of methanol on MgO defective surfaces have been calcd. by periodic DFT simulations. The results are very comparable with those obtained with water and are also in very good accordance with microcalorimetry and IR expts. At low…

Organo-NOx formation-decomposition as the origin of the changes in the low temperature NO-TPD profile in the presence of n-decane on Ag/γ-Al2O3

Kinga Malinger, Juliette Blanchard, Rachel P. Doherty, Cyril Thomas

The NOx desorption profiles obtained in O2-He and n-C10-O2-He were compared on γ-Al2O3 and Ag/γ-Al2O3. On Ag/γ-Al2O3, the low-temperature NOx desorption profiles obtained in n-C10-O2-He were significantly different from those obtained in O2-He. In particular, at 190-220 °C excess release of NO,…

Non-biological selectivity in amino acids polymerization on TiO2 nanoparticles

Maguy Jaber, Jolanda Spadavecchia, Houssein Bazzi, Thomas Georgelin, France Costa-Torro, Jean-François Lambert

For the first, time a strong selectivity is evidenced in inorganic peptide synthesis. When an equimolar mixture of Ala and Arg monomers is added to the synthesis medium of TiO2 nanoparticles from Ti(IV) isopropoxide in benzyl alcohol, the Ala-Arg dipeptide is observed by 13C NMR in the resulting…
