Stability of Binary SAMs Formed by omega-Acid and Alcohol Functionalized Thiol Mixtures

Frederik Tielens, Vincent Humblot, Claire-Marie Pradier, Monica Calatayud, Francesc Illas

A simple model is presented to describe the mixing process of acid- and alcohol-terminated thiol self-assembled monolayers (SAMs) on Au(111). It was found that the low-concentration acid-terminated SAMs are enriched in acid thiol compared with the original solution from which the SAM is made. Due…

Does the S-H Bond Always Break after Adsorption of an Alkylthiol on Au(111)?

Hazar Guesmi, Noelia B. Luque, Elizabeth Santos, Frederik Tielens

The reaction mechanism for the formation of alkyl thiol self-assembled monolayers (SAM) on Au(111) is still not clearly understood. Especially, the role of defects on the chemisorption process is an important goal to be addressed. In this work, different minimum energy reaction paths for R−SH…

Insight into the mechanism of action of temporin-SHa, a new broad-spectrum antiparasitic and antibacterial agent

Zahid Raja, Sonia André, Feten Abbassi, Vincent Humblot, Olivier Lequin, Tahar Bouceba, Isabelle Correia, Sandra Casale, Thierry Foulon, Denis Sereno, Bruno Oury, Ali Ladram

Antimicrobial peptides (AMPs) are promising drugs to kill resistant pathogens. In contrast to bacteria, protozoan parasites, such as Leishmania, were little studied. Therefore, the antiparasitic mechanism of AMPs is still unclear. In this study, we sought to get further insight into this mechanism…

Effect of ceria promotion on the catalytic performance of Ni/SBA-16 catalysts for CO 2 methanation

Chao Sun, Patricia Beaunier, Patrick da Costa

The presence of Ce inside the SBA-16 structure promoted the ratio of Ce 3+ and medium basic sites and thus favoured CH 4 formation.

Preparation of Pt°/MCM-41: effect of drying on MCM-41 structure and Pt° dispersion

Baichun Zhu, Franck Letellier, Juliette Blanchard, Katia Fajerwerg, Catherine Louis, Denis Guillaume, Denis Uzio, Miehèle Breysse

Pt°/MCM-41 catalysts were prepared by electrostatic adsorption of Pt(NH3)42+ at pH=8, followed by calcination under O2 and reduction. This procedure allows to prepare highly dispersed Pt° nanoparticles (D>76%), but has the drawback to modify significantly the structure of the ordered mesoporous…

Mechanisms of Adsorption of Short Peptides on Metal and Oxide Surfaces

Vincent Humblot, Jessem Landoulsi, Claire-Marie Pradier

Biointerfaces, involving peptides or proteins and solid surfaces, have been investigated with the aim of controlling the behavior/reactivity of inorganic materials in biological environments. This chapter presents a comprehensive overview of the basic aspects governing the interaction of short…
