Bioconjugated gold nanorods to enhance the sensitivity of FT-SPR-based biosensors

Jolanda Spadavecchia, Sandra Casale, Souhir Boujday, Claire-Marie Pradier

n this paper, we report a feasible solvent-free approach for the synthesis and self-assembling of gold nanorods after bioconjugation to antibodies; scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images revealed a remarkable shape and size narrow distribution, as well…

Influence of the nature and environment of manganese in Mn-BEA zeolites on NO conversion in selective catalytic reduction with ammonia

Rafal Baran, L. Valentin, J.-M. Krafft, T. Grzybek, P. Glatzel, Stanislaw Dzwigaj

Manganese-containing BEA zeolites, MnxSiBEA (x = 1–4 wt %) and Mn(I.E.)AlBEA, were prepared by a two-step postsynthesis method and a conventional wet ion-exchange, respectively, and applied as catalysts in the selective catalytic reduction of NO with ammonia (NH3-SCR). The physicochemical analysis…

Supramolecular chiral self-assemblies of Gly–Pro dipeptides on metallic fcc(110) surfaces

C. Methivier, H. Cruguel, C.-M. Pradier, V. Humblot

Adsorption of the Glycine-Proline (Gly-Pro) dipeptide has been investigated using surface science complementary techniques on Au(110) and Ag(110), showing some interesting differences both in the chemical form and surface organization of the adsorbed peptide. On Au(110), Gly-Pro mainly adsorbs in…

Controlling C−OAryl Hydrogenolysis vs Aryl Hydrogenation in Lignin Model Depolymerization Using Ni‐, Rh‐ or Ni/Rh‐based Silica Catalysts

Rita Raachini, Ferdaous Ben Romdhane, Capucine Sassoye, Maya Boutros, Franck Launay

Abstract This paper focuses on the hydrogenolysis of 2‐phenoxy‐1‐phenylethanone, modelling a pre‐oxidized form of lignin using five catalysts of similar metal content, prepared by impregnation of Ni(II), Rh(III) and both metals onto Aerosil‐380 in the presence of NH 3 , followed by a reduction step…

Plastic waste recycling via pyrolysis: A bibliometric survey and literature review

Sabino Armenise, Wong Syieluing, José M Ramírez-Velásquez, Franck Launay, Daniel Wuebben, Norzita Ngadi, Joaquín Rams, Marta Muñoz

Plastic materials have been crucial to the development of science, technology, and almost all aspects of modern progress since the mid-twentieth century. However, the increasingly unsustainable culture of plastic consumption and the accumulation of plastics in landfills, oceans, and broader…

Synthesis of Hybrid Polyphenol/Hydroxyapatite Nanomaterials with Anti-Radical Properties

Estelle Palierse, Sylvie Masse, Guillaume Laurent, Patrick Le Griel, Gervaise Mosser, Thibaud Coradin, Claude Jolivalt

Plant-derived natural bioactive molecules are of great therapeutic potential but, so far, their application in nanomedicine has scarcely been studied. This work aimed at comparing two methodologies, i.e., adsorption and in situ incorporation, to prepare hybrid polyphenol/hydroxyapatite…

PET waste as organic linker source for the sustainable preparation of MOF-derived methane dry reforming catalysts

Leila Karam, Arianna Miglio, Stefania Specchia, Nissrine El Hassan, Pascale Massiani, Julien Reboul

A catalyst made of Ni 0 nanoparticles highly dispersed on a lamellar alumina support was prepared by an environmentally-friendly route. The latter involved the synthesis of an aluminum-containing metalorganic framework (MOF) MIL-53(Al) in which the linkers were derived from the depolymerization of…

Catalyseur hybride métal-zéolithe pour l'oxydation électrochimique de l'acide formique

Lu Zhang, J.V. Perales-Rondon, Angélica Thomère, Juliette Blanchard, Carlos M Sánchez-Sánchez, Vincent Vivier

La production d’énergie par voie électrochimique peut être envisagée comme un substitut à l’utilisation de combustibles fossiles ou nucléaires. Parmi les différents composants d’une pile à combustible, l’électrocatalyseur joue un rôle major. [1] Les zéolithes sont des aluminosilicates cristallins…

Influence of the postsynthesis preparation procedure on catalytic behaviour of Ag-loaded BEA zeolites in the hydrodechlorination of 1,2-dichloroethane into value added products

A. Śrębowata, R. Baran, G. Słowik, D. Lisovytskiy, Stanislaw Dzwigaj

Two silver-containing BEA zeolites prepared by a two-step postsynthesis method (Ag2.0SiBEA) and a conventional wet impregnation (Ag2.0HAlBEA) showed a high activity in the conversion of 1,2-dichloroethane (1,2-DCE) into value added products with 100% selectivity into ethylene and 100% selectivity…

Steam reforming of alpha-methylnaphthalene as a model tar compound over olivine and olivine supported nickel

Rudy Michel, Agata Lamacz, Andrzej Krzton, Gérald Djéga-Mariadassou, Philippe Burg, Claire Courson, Rene Gruber

At high temperature, biomass steam gasification generates tars and more particularly Polycyclic Aromatic Hydrocarbons (PAHs). To assess the ability of olivine-based catalyst to eliminate the tars by steam reforming, alpha-methylnaphthalene (MNP) was chosen as model compound. The Ni/olivine has…
