Structured hybrid nanoparticles via surface-initiated ATRP of methyl methacrylate from ordered mesoporous silica

F. Audouin, H. Bias, P. Pasetto, P. Beaunier, C. Boissiere, C. Sanchez, M. Save, B. Charleux

Structured hybrid nanoparticles were synthesized via surface-initiated atom transfer radical polymerization of MMA from ordered mesoporous silica (QMS) nanoparticles with various morphologies. The design of the QMS particles was adjusted to target either spherical core-shell or cylindrical…

Drastic Au(111) Surface Reconstruction upon Insulin Growth Factor Tripeptide Adsorption

Vincent Humblot, Anne Vallee, Ahmed Naitabdi, Frederik Tielens, Claire-Marie Pradier

Adsorption of biomolecules at metal surfaces often creates two-dimensional ordering of the adlayers. However, metal substrate reconstruction is less commonly observed, unless upon annealing of the molecule−surface system. Here, we report on the drastic room-temperature reconstruction of the Au(111…

Synthesis and Treatment Parameters for Controlling Metal Particle Size and Composition in Cu/ZnO MaterialsFirst Evidence of Cu3Zn Alloy Formation

Salim Derrouiche, Hélène Lauron-Pernot, Catherine Louis

This paper deals with the study of the conditions of obtention of small metal copper particles on ZnO using easy synthesis methods and activation treatments, which were found "efficient" for the preparation of copper particles on silica, that is, deposition-precipitation with urea and…

Ag–Ni bimetallic SiBEA zeolite as an efficient catalyst of hydrodechlorination of 1,2-dichloroethane towards ethylene

A Śrębowata, I Zielińska, R Baran, G Słowik, S Dzwigaj

Dealuminated form of BEA zeolite with Si/Al ratio of 1500 was used for the synthesis of Ag2.0SiBEA, Ni2.0SiBEA and Ag2.0Ni2.0SiBEA by two-step postsynthesis method. The calcination of zeolite samples led to the formation of well dispersed isolated mononuclear Ag(I) and Agnδ + clusters and a pseudo-…

Effect of the activation temperature on the state of gold supported on titania: An FT-IR spectroscopic study

Tz. Venkov, Katia Fajerwerg, L. Delannoy, Hr. Klimev, K. Hadjiivanov, C. Louis

The effect of the pre-treatment conditions on the evolution of gold species on an Au/TiO2 sample prepared by deposition–precipitation with urea has been followed by FT-IR spectroscopy of adsorbed CO. Gold is in the form of Au3+ species on the as-prepared sample and is not affected by evacuation at…

Conversion of syngas-derived C 2 + mixed oxygenates to C 3 –C 5 olefins over Zn x Zr y O z mixed oxide catalysts

Colin Smith, Vanessa Lebarbier Dagle, Matthew Flake, Karthikeyan K. Ramasamy, Libor Kovarik, Mark Bowden, Thomas Onfroy, Robert A. Dagle

In this study we report on a ZnxZryOz mixed oxide type catalyst capable of converting a syngas-derived C2+ mixed oxygenate feedstock to isobutene-rich olefins. Aqueous model feed comprising of ethanol, acetaldehyde, acetic acid, ethyl acetate, methanol, and propanol was used as representative…

Gold surface nanostructuring for separation and sensing of biomolecules, Nanostructuration des surfaces d'or pour la séparation et la détection de biomolécules

Erin Bedford

Detecting biomolecules in physiological environments is critical to health care and environmental monitoring. In this work, we study and use gold surfaces for biomolecule detection while incorporating nanoscale components—specifically, self-assembled monolayers (SAMs) of alkanethiols and gold…, La détection de molécules biologiques dans les environnements physiologiques est essentielle aux soins de santé et la surveillance de l'environnement. Dans ces travaux de thèse, nous étudions et utilisons des surfaces d'or pour la détection de biomolécules, avec l'inclusion de…

Ordered Nanostructures on a Hydroxylated Aluminum Surface through the Self-Assembly of Fatty Acids.

Irma Liascukiene, Nesrine Aissaoui, Svajus J. Asadauskas, Jessem Landoulsi, Jean-François Lambert

We investigate the mechanism of self-assembly of fatty acids (FA) and methyl oleate on an Al oxy-hydroxide surface with a view to deciphering the role and nature of interfacial processes (adsorption, chemical binding, molecular organization, etc.). For this purpose, we focus on parameters related…
