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…

Application of Arrhenius law to DP and zero-span tensile strength measurements taken on iron gall ink impregnated papers: relevance of artificial ageing protocols

Véronique Rouchon, Oulfa Belhadj, Maroussia Duranton, Alice Gimat, Pascale Massiani

Iron gall inks (IGI) were largely used for writing until the nineteenth century. Under certain circumstances, they provoke a substantial degradation of their cellulosic support.It was shown in a previous works thatc ombination of oxygen and iron largely impacts cellulose chain breaking occurring in…

Unveiling the M−F/OH bonding and anionic ordering in Mg, Zn, Cu−based hydroxyfluorides for the design of basic catalysts

Helies Boumali, Matthew R. Suchomel, Étienne Durand, Thomas Onfroy, Guillaume Laugel, Hélène Pernot

Functional inorganic materials, mostly oxides but also fluorides, sulfides, or nitrides has led to the development of many modern technologies. The usual way to improve the chemical and physical properties of these materials was the cationic substitution in order to tune the chemical bonding. These…

Enhanced activity of NiZrBEA catalyst for upgrading of biomass pyrolysis vapors to H2-rich gas

Jacek Grams, Robert Ryczkowski, Renata Sadek, Karolina Chałupka-Śpiewak, Sandra Casale, Stanislaw Dzwigaj

The main objective of these studies was development of competitive catalyst for the upgrading of biomass pyrolysis vapors to H2-rich gas. The performed experiments were devoted to determination of the effect of incorporation of zirconium into the structure of BEA zeolite on the performance of NiBEA…

Assessment of the capability of Fe and Al modified BEA zeolites to promote advanced oxidation processes in aqueous phase

Erick Bandala, Renata Sadek, Jacek Gurgul, Kazimierz Łątka, Małgorzata Zimowska, Laetitia Valentin, Oscar Rodriguez-Narvaez, Stanislaw Dzwigaj

Iron-containing zeolites were prepared using two-step postsynthesis and wet impregnation methods and characterized using conventional techniques. The materials were tested for production of hydroxyl radicals using N,N-dimethyl-p-nitrosoaniline (pNDA) as radical scavenger and discoloration of Congo…
