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…

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…

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…

Effects of organic and inorganic treatment agents on the formation of conversion layer on hot-dip galvanized steel: An X-ray photoelectron spectroscopy study

S. Le Manchet, D. Verchere, Jessem Landoulsi

The formation of a Cr-free conversion layer on hot-dip galvanized (HDG) steel involves various interfacial processes which radically influence the composition of the coating and thus its performance. Here, we investigate the role of the main constituents contained in the treatment bath, the…

Transition-Metal-Free Catalysts for the Sustainable Epoxidation of Alkenes: From Discovery to Optimisation by Means of High Throughput Experimentation

Warunee Lueangchaichaweng, Inge Geukens, Annelies Peeters, Benjamin Jarry, Franck Launay, Jean-Luc Bonardet, Pierre A. Jacobs, Paolo P. Pescarmona

Abstract: Transition-metal-free oxides were studied as heterogeneous catalysts for the sustainable epoxidation of alkenes with aqueous H2O2 by means of high throughput experimentation (HTE) techniques. A full-factorial HTE approach was applied in the various stages of the development of the…

Adsorption of Amino Acids and Peptides on Metal and Oxide Surfaces in Water Environment: A Synthetic and Prospective Review

D. Costa, L. Savio, Claire-Marie Pradier

Amino acids and peptides are often used as “model” segments of proteins for studying their behavior in various types of environments, and/or elaborating functional surfaces. Indeed, though the protein behavior is much more complex than that of their isolated segments, knowledge of the binding mode…
