Gold, Silver, and Iron Oxide Nanoparticle Incorporation into Silk Hydrogels for Biomedical Applications: Elaboration, Structure, and Properties

Cristina Belda Marín, Christophe Egles, Vincent Humblot, Yoann Lalatonne, Laurence Motte, Jessem Landoulsi, Erwann Guénin

Silk fibroin (SF) is a versatile material with biodegradable and biocompatible properties, which make it fit for broad biomedical applications. In this context, the incorporation of nanosized objects into SF allows the development of a variety of bionanocomposites with tailored properties and…

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…

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…

A microGC study of the deactivation process during conversion of methylbutynol on basic zeolites

Pascale Massiani, Jean-François Groust, Guylène Costentin, Laurent Teyssier

The initial deactivation occurring during conversion of methylbutunol on basic alkali-faujasite catalysts was studied by microGC. Both the product selectivity and the formation of water during the first minutes of run permit to conclude on the deactivation process and on the nature of the adsorbed…

Mechanism of Metal Oxide Nanoparticle Loading in SBA-15 by the Double Solvent Technique

Juliette van Der Meer, Isabelle Bardez-Giboire, Cyrille Albert-Mercier, Bertrand Revel, Anne Davidson, Renaud Denoyel

The interaction between SBA-15 mesoporous silica, alkane solvents, and water was studied to understand the mechanism of the so-called double solvent technique. This method facilitates the loading of the pores of SBA-15 with a metal oxide precursor soln., by prewetting the SBA-15 with an alkane. In…

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…

Inelastic light scattering by long narrow gold nanocrystals: when size, shape, crystallinity and assembly matter

Hervé Portalès, Nicolas Goubet, Sandra Casale, Xiang Zhen Xu, Mostapha Ariane, Alain Mermet, Jeremie Margueritat, Lucien Saviot

We report the synthesis of long narrow gold nanocrystals and the study of their vibrational dynamics using inelastic light scattering measurements. Rich experimental spectra are obtained for monodomain gold nanorods and pentagonal twinned bipyramids. Their assignment involves diameter-dependent non…
