Chiral Recognition of l-Gramicidine on Chiraly Methionine-Modified Au(111)

Vincent Humblot, Claire-Marie Pradier

A chiral pentadecapeptide, l-gramicidine, has been shown to undergo specific adsorption onto gold surfaces modified by chiral amino acids, d- and l-methionine, upon adsorption in the liquid phase. There is a chiral recognition only between the slightly anionic l-peptide and the l-modified surface…

Monitoring of the Plasmon Resonance of Gold Nanoparticles in Au/TiO2 Catalyst under Oxidative and Reducing Atmospheres

Yves Borensztein, Laurent Delannoy, Anis Djedidi, Ruben G. Barrera, Catherine Louis

Diffuse optical reflectance of Au/TiO2 powder catalysts, prepared by the deposition-precipitation method, is measured in the UV-visible range in controlled atmosphere. An intense optical absorption observed around 550 nm is interpreted by the excitation of plasmon resonances in the 4 nm gold…

Nanocrystalline NbC formation from mesostructured niobium oxide studied by HRTEM, SAED and in situ XRD

S. Witkowski, M. Ruszak, Celine Sayag, J. Pielaszek, G. Djéga-Mariadassou

Mechanism of the nanometric size niobium carbide synthesis from mesostructured niobium oxide precursor is proposed. High-resolution transmission electron microscopy (HRTEM) and selected area electron diffraction (SAED) combined with in situ X-ray diffraction (XRD) were successfully used to study…

The influence of the preparation procedures on the catalytic activity of Fe-BEA zeolites in SCR of NO with ammonia and N2O decomposition

Paweł Boroń, Lucjan Chmielarz, Jacek Gurgul, Kazimierz Łątka, Barbara Gil, Jean-Marc Krafft, Stanislaw Dzwigaj

Three series of Fe-containing BEA zeolites are prepared by two-step postsynthesis (PS), ion exchange (IE) and conventional wet impregnation (Imp) procedures with various Fe content (1.0–4.0 Fe wt.%). In these series of zeolites iron is mainly present as pseudo-tetrahedral Fe(III) as evidenced by…

Application of computational approach in plastic pyrolysis kinetic modelling: a review

Sabino Armenise, Syieluing Wong, José M Ramírez-Velásquez, Franck Launay, Daniel Wuebben, Bemgba B Nyakuma, Joaquín Rams, Marta Muñoz

During the past decade, pyrolysis routes have been identified as one of the most promising solutions for plastic waste management. However, the industrial adoption of such technologies has been limited and several unresolved blind spots hamper the commercial application of pyrolysis. Despite many…

Photocatalytic Easy Recovery of Orthophosphates Contaminants in Water Using Amberlite‐732 Cationic‐Resin Exchanged by Ce 3+ and Ce 3+ ‐Au 3+ Species

Phds. Nawel Rahmoune, Siham Barama, Anne Davidson, David Montero, Mohamed Selmane, Antoine Miche, Fouad Benaliouche, Akila Barama

This report discusses the efficiency of photo-recovery of orthophosphate anions in water under visible irradiation using materials containing amorphous carbon, ceria and gold-ceria species. Catalysts were obtained by the exchange of Amberlite-732 polymeric-resin with isolated Ce(III) and co-mixing…

Revisiting Alkoxysilane Assembly on Silica Surfaces: Grafting versus Homo-Condensation in Solution

Yannick Millot, Antoine Hervier, Jihed Ayari, Naoures Hmili, Juliette Blanchard, Souhir Boujday

Silica surface functionalization is mandatory for a large variety of applications. This step is often done through the condensation of functional silanes on silanol, silica surfaces' terminal groups. Among these silanes, aminopropyltriethoxysilane (APTES) is widely used due to its assumed high…

Mueller micropolarimeter for color imaging of aluminium metasurfaces

M. Nicolas, I. Soumahoro, L. Zhang, G. Guida, W. Daney de Marcillac, D. Demaille, C. Schwob, S. Boujday, Bruno Gallas

Many anticounterfeiting tags rely on images intricate in different color and/or different polarization states to create optical effects invisible in conventional observation conditions. We build here an imaging micropolarimeter based on the dual rotating compensator system and using the color…

Organic pollutant adsorption on clay minerals

Jean-François Lambert

This Chapter is focused on the interactions of organic pollutants with clay minerals and related phenomena. It covers a diverse group of xenobiotic organic molecules that include pesticides, pharmaceuticals, industrial pollutants, and dyes. After an initial classification of these molecules…
