Elaboration of antibiofilm surfaces functionalized with antifungal-cyclodextrin inclusion complexes.

Aïcha Gharbi, Vincent Humblot, Turpin Frédéric, Claire-Marie Pradier, Christine Imbert, Jean-Marc Berjeaud

To tackle the loss of activity of surfaces functionalized by coating and covalently bound molecules to materials, an intermediate system implying the noncovalent immobilization of active molecules in the inner cavity of grafted cyclodextrins (CDs) was investigated. The antifungal and antibiofilm…

Ultrafast time-resolved quantum cascade laser diagnostic for enlightening the role of surface formate species in the photocatalytic oxidation of methanol

Josefine Schnee, Marco Daturi, Mohamad El-Roz

In the present work, a new quantum cascade laser (QCL)-assisted operando FT-IR setup was used to get direct insight into the relationship between the overall catalytic performance of TiO2 photocatalysts in the gas phase photooxidation of methanol at 25 °C, and the kinetics of intermediate surface…

Effects of dealumination on the performance of Ni-containing BEA catalysts in bioethanol steam reforming

Wojciech Gac, Magdalena Greluk, Grzegorz Słowik, Yannick Millot, Laetitia Valentin, Stanislaw Dzwigaj

The effects of dealumination of BEA zeolite on the formation of nickel active sites and the performance of Ni-containing BEA zeolite catalysts in the steam reforming of ethanol have been studied. Ni-containing BEA zeolite catalysts were prepared by the impregnation of unmodified and dealuminated…

The state of BEA zeolite supported nickel catalysts in CO2 methanation reaction

Wojciech Gac, Witold Zawadzki, Grzegorz Słowik, Marcin Kuśmierz, Stanislaw Dzwigaj

Two model nickel catalysts for CO2 methanation reaction were prepared by the impregnation method using unmodified and dealuminated BEA-type zeolite supports, denoted NiHAlBEA and NiSiBEA. Transmission electron microscopy (TEM) and X-ray diffraction studies evidenced formation of metallic nickel…

Chemical Differentiation of Planets: A Core Issue

Hervé Toulhoat, Viacheslav Zgonnik

By plotting empirical chemical element abundances on Earth relative to the Sun and normalized to silicon versus their first ionization potentials, we confirm the existence of a correlation reported earlier. To explain this, we develop a model based on principles of statistical physics that predicts…

Covalent Grafting of Polyoxometalate Hybrids onto Flat Silicon/Silicon Oxide: Insights from POMs Layers on Oxides

Maxime Laurans, Kelly Trinh, Kevin Dalla Francesca, Guillaume Izzet, Sandra Alves, Etienne Derat, Vincent Humblot, Olivier Pluchery, Dominique Vuillaume, Stéphane Lenfant, Florence Volatron, Anna Proust

Immobilization of polyoxometalates (POMs) onto oxides is relevant to many applications in the fields of catalysis, energy conversion/storage, or molecular electronics. Optimization and understanding the molecule/oxide interface is crucial to rationally improve the performance of the final molecular…
