Hybrid Hydrophobin/Gold Nanoparticles: Synthesis and Characterization of New Synthetic Probes for Biological Applications

Jane Politi, Luca de Stefano, Paola Giardina, Sandra Casale, Ilaria Rea, Jolanda Spadavecchia

We report a simple and original method to synthesize gold nanoparticles in which a fungal protein, the hydrophobin Vmh2 from Pleurotus ostreatus, mixed to cetyltetrammonium bromide (CTAB) has been used as additional component in a one-step synthesis, leading to shell-like hybrid protein-metal…

Phosphoribosyl Pyrophosphate: A Molecular Vestige of the Origin of Life on Minerals

Mariame Akouche, Maguy Jaber, Marie-Christine Maurel, Jean-François Lambert, Thomas Georgelin

In this contribution, we report the formation under prebiotic conditions of phosphoribosyl pyrophosphate (PRPP) as a molecular precursor in the one-pot synthesis of a canonical nucleotide, namely adenosine monophosphate (AMP) from its building blocks (KH2PO4 or Pi, adenine, and d-ribose), on a…

Passivation behaviour of stainless steel (UNS N-08028) in industrial or simplified phosphoric acid solutions at different temperatures

M. Ben Salah, René Sabot, Philippe Refait, Irma Liascukiene, Christophe Méthivier, Jessem Landoulsi, Leila Dhouibi, Marc Jeannin

The corrosion behaviour of Sanicro28, in industrial phosphoric acid and simplified solution of pure H3PO4 containing sulphates and chlorides, is investigated during 48 h between 20 and 80 °C. Results show higher corrosion resistance in the industrial medium. Film thickness evaluated by EIS remains…

Role of nitrite species during the formation and transformation of the Fe(II–III) hydroxycarbonate green rust

Philippe Refait, Mohammed Reffass, Jessem Landoulsi, René Sabot, Marc Jeannin

The Fe(II–III) hydroxycarbonate green rust, GR(CO32−), can be prepared by oxidation of aerated aqueous suspensions of Fe(II) hydroxide. The effects of nitrite ions on the formation and oxidation of GR(CO32−) were then studied by adding NaNO2 just after the precipitation of Fe(OH)2 or once GR(CO32−)…

Baicalein-modified hydroxyapatite nanoparticles and coatings with antibacterial and antioxidant properties

Estelle Palierse, Christophe Hélary, Jean-Marc Krafft, Isabelle Génois, Sylvie Masse, Guillaume Laurent, Maria I Alvarez Echazu, Mohamed Selmane, Sandra Casale, Laetitia Valentin, Antoine Miche, Ben C.L. Chan, Clara B.S. Lau, Margaret Ip, Martin F Desimone, Thibaud Coradin, Claude Jolivalt

Aseptic loosening and bacterial infections are the two main causes of failure for metallic implants used for joint replacement. A coating that is both bioactive and possesses antimicrobial properties may address such shortcomings and improve the performance of the implant. We have sought to study…

Influence of the texturalproperties of porousaluminas on the reducibility of Ni/Al2O3 catalysts

Faiza Bentaleb, Eric Marceau

Temperature-programmed reduction (TPR) profiles recorded on calcined Ni/Al2O3 catalysts exhibiting the same Ni(II) surface density (3 Ni2+ nm−2) suggest that nickel speciation and reducibility are significantly influenced by the specific surface area and texturalproperties of aluminas, and by their…

Microstructural, morphological characterization and corrosion behavior of sand cast AlSi10Cu(Fe) alloy in chloride solution

Belkacem Korichi, Nacer Zazi, Stéphanie Delbrel, Kieu Ngo, Jean Paul Chopart

In order to examine the relationship between the microstructure and the corrosion behavior in chloride solution, the microstructure of AlSi10Cu (Fe) sand cast aluminum alloy has been investigated by using different techniques including scanning electron microscopy, energy-dispersive spectroscopy, X…

Leila Karam, M. Carmen Bacariza, José David Lopes, Carlos Henriques, Pascale Massiani, Nissrine El Hassan

Mesoporous xNi-yMg-Al2O3 catalysts prepared by combined evaporation induced self-assembly (EISA) and one-pot techniques were tested in CO2 methanation reaction. All calcined/reduced materials were characterized by X-ray fluorescence (XRF), X-ray diffraction (XRD), N2 physisorption,…

Effect of SAM chain length and binding functions on protein adsorption: β-Lactoglobulin and apo-transferrin on gold.

Erin E. Bedford, Vincent Humblot, Frank X. Gu, Claire-Marie Pradier

Controlled immobilization of proteins is crucial in many applications, including biosensors. Allergen biosensing, for example, requires molecular recognition of suitably immobilized proteins by specific antibodies and sensitive measurement of this interaction. Self-assembled monolayers (SAMs),…
