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.

Au-Modified Pd catalyst exhibits improved activity and stability for NO direct decomposition

Taha Elgayyar, Josefine Schnee, Alain Tuel, Laurence Burel, Francoise Bosselet, Yves Schuurman, Frederic C Meunier, Laurent Delannoy, Cyril Thomas

The direct decomposition of NO x at moderate temperatures is a challenge because of the poisoning of the surface of noble metals by oxygen, yet the modification of Pd with Au enables obtaining a highly stable catalyst under an O 2-free feed at 450°C. Care was taken to ensure that the reaction was…

C3-Alkylation of furfural derivatives by continuous flow homogeneous catalysis

Grédy Kiala Kinkutu, Catherine Louis, Myriam Roy, Juliette Blanchard, Julie Oble

The C3-functionalization of furfural using homogeneous ruthenium catalysts requires the preinstallation of an ortho -directing imine group, as well as high temperatures, which did not allow scaling up, at least under batch conditions. In order to design a safer process, we set out to develop a…

Fast and potent bactericidal membrane lytic activity of PaDBS1R1, a novel cationic antimicrobial peptide

Luz N Irazazabal, William F Porto, Isabel C.M. Fensterseifer, Eliane S.F. Alves, Carolina Matos, Antônio C.S. Menezes, Mário R Felício, Sónia Gonçalves, Nuno Santos, Suzana M Ribeiro, Vincent Humblot, Luciano M Lião, Ali Ladram, Octavio L Franco

Antimicrobial peptides (AMPs) are promising candidates for the development of future antibiotics. In an attempt to increase the efficacy of therapeutic AMPs, computer-based design methods appear as a reliable strategy. In this study, we evaluated the antimicrobial efficiency and mechanism of action…

Iron topochemistry and surface reactivity of amphibole asbestos: relations with in vitro toxicity

A. Pacella, Giovanni B. Andreozzi, Jeanine Fournier, Lorenzo Stievano, F. Giantomassi, Guendalina Lucarini, Maria Rita Rippo, A. Pugnaloni

Chemical reactivity of asbestos tremolite from Italy and USA localities and Union Internationale Contre le Cancer (UICC) crocidolite was studied in relation to Fe content, oxidation state, and structural coordination. Direct correlation between amount of Fe2+ at the exposed M(1) and M(2) sites of…

Detailed crystal chemistry and iron topochemistry of asbestos occurring in its natural setting: A first step to understanding its chemical reactivity

A. Pacella, G. B. Andreozzi, Jeanine Fournier

Five samples of tremolite asbestos from Italy and USA were fully characterized by ICP-MS, SEM, EMPA, FT-IR, MS, XRPD, to correlate crystal chemistry with chemical reactivity. Iron topochemistry was investigated in detail, due to the role of Fe in the aetiology of respiratory inflammatory diseases.…

Design of TiO2/Au nanoparticle films with controlled crack formation and different architectures using a centrifugal strategy

Abdelhafed Taleb, Frederic Mesguich, Thomas Onfroy, Xue Yanpeng

Here we present an approach to design hybrid nanocomposite films based on TiO2/Au nanoparticles using centrifugation processes. The prepared nanocomposite films have been characterized by different techniques such as FEGSEM, TEM, BET and XRD. Furthermore it is demonstrated that centrifugal force…

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…
