Juan Ramirez Henao, Souhir Boujday, Claire Wilhelm, Basile Bouvet, Somia Tomane, Ioanna Christodoulou, Daoming Sun, Guilhem Cure, Ferdaous Ben Romdhane, Antoine Miche, Anne Dolbecq, Pierre Mialane, Anne Vallée

A reduced polyoxometalate (POM) functionalized with bisphosphonate (BP) ligands possessing antitumoral properties was used to synthesize metallic gold nanostars (AuNSs) with high reproducibility through a silver-assisted seed growth method. Notably, this study is the first to employ a reduced…

Toward new proton exchange batteries based on ionic liquid electrolyte: Metal hydride electrode / electrolyte coupling

Nesrine Chaabene, J. Zhang, Mireille Turmine, E. Kurchavova, Vincent Vivier, F. Cuevas, M. Mateos, M. Latroche, J. Monnier

The voltage of an alkaline electrolyte-based battery is limited by the narrow electrochemical stability window of water. As an alternative to water, protic ionic liquid (IL)-based electrolytes have shown excellent conducting properties as well as a wide electrochemical stability window, and can…

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,…

Alternated p-Conjugated Polymers Based on a 1,2- Diiminocyclohexane Chiral Unit for Nitroaromatics Sensing

Simon Clavaguera, Olivier J. Dautel, Lionel Hairault, Christophe Méthivier, Pierre Montméat, Eric Pasquinet, Claire-Marie Pradier, Françoise Serein-Spirau, Salem Wakim, Florian Veignal, Joël J.E. Moreau, Jean-Pierre Lère-Porte

The detection of 2,4-dinitrotoluene (DNT) by fluorescence quenching of a new class of polyimines consisting in p-conjugated segments regularly alternated with chiral C2 symmetry units has been studied for solutions and thin films. Their photophysical properties and their sensitivity towards DNT…

Probing Peptide-inorganic surface interaction at the single molecule level using force spectroscopy.

Jessem Landoulsi, Vincent Dupres

We investigate the interaction between D-Ala-D-Ala peptide and a stainless steel (SS) surface by AFM force spectroscopy with view to understand the role and nature of interfacial processes at the single molecule level. For this purpose, force-distance curves were recorded between the D-Ala-D-Ala…

Nickel(II) Nitrate vs. Acetate: influence of the Precursor on the Structure and Reducibility of Ni/MCM-41 and Ni/Al-MCM-41 Catalysts

Eric Marceau, Michel Che, Jiri Cejka, Arnost Zukal

Nickel(II) nitrate is the nickel precursor generally selected to prep. oxide-supported catalysts, due to its low cost, high soly. in water and decompn. at moderate temps. However, its decompn. produces NOx, and it is known to melt and redistribute over the support upon heating, leading to poorly…

Chemisorbed atomic oxygen inducing Pd segregation in PdAu(111) alloy: Energetic and electronic DFT analysis

Hazar Guesmi, Catherine Louis, Laurent Delannoy

Segregation energies of isolated Pd in PdAu(1 1 1) alloy are investigated by DFT calculations as a function of the oxygen coverage. Segregation of Pd is found to be oxygen-coverage dependent. While for 'clean' PdAu(1 1 1), Pd prefers to be in the bulk, in the presence of more than 1/3 ML…

Phase cycling in MQMAS sequences for half-integer quadrupole spins

Redouane Hajjar, Yannick Millot, Pascal P. Man

A review presents the anal. expressions of the first- and second-order quadrupole interactions for a static crystal, and for a crystal rotating at variable or magic angle. It also provides mathematica notebooks for calcg. the anal. expressions of existing interactions. Nested phase cycling in MQMAS…

Biosensors elaborated on gold nanoparticles, a PM-IRRAS characterisation of the IgG binding efficiency.

Anne-Laure Morel, Souhir Boujday, Christophe Méthivier, Jean-Marc Krafft, Claire-Marie Pradier

This work is focused on studying the grafting of gold nanoparticles (Np) on a cystamine self-assembled monolayer on gold, in order to build sensitive immunosensors. The synthesis and deposition of gold nanoparticles, 13 and 55 nm sizes, were characterised by combining Polarisation Modulation…
