Development of a microfluidic redox flow battery, Développement d'une batterie redox flow à puce microfluidique

Youssef Kharchouf

This thesis project integrates the two fields of microfluidic redox flow batteries and computation modelling. The first axis of research continues the investigation of the usability of Ionic Liquids as supporting electrolytes for microfluidic redox flow batteries due to their attractive properties…, Ce projet de thèse intègre les deux domaines des batteries à flux redox microfluidiques et de la modélisation numérique. Le premier axe de recherche poursuit l'examination de l'utilisabilité des Liquides Ioniques en tant qu'électrolytes supports pour les batteries redox flow…

The ionic liquid route for the development of environmentally friendly corrosion inhibitors : the inhibition of mechanism of ammonium and amino-acid based ionic liquids for high strength al alloys

Oumaïma Gharbi, Mai T.T. Tran, Mireille Turmine, Vincent Vivier

The research and development of environmentally friendly alternatives for chromate-based surface treatments and coating has considerably accelerated over the last decades. In fact, as a result of the recent European legislation restrictions toward chromate use and disposal, several promising…

Remarkable effect of postsynthesis preparation procedures on catalytic properties of Ni-loaded BEA zeolites in hydrodechlorination of 1,2-dichloroethane

A. Śrębowata, R. Baran, D. Łomot, D. Lisovytskiy, T. Onfroy, S. Dzwigaj

Ni2.0SiBEA and Ni2.0HAlBEA zeolites were prepared by two different procedures: (i) a two-step postsynthesis method that consist of (1) creation of vacant T-atom sites by dealumination of HAlBEA (Si/Al = 17) with nitric acid and then (2) impregnation of as resulting SiBEA (Si/Al > 1300) with…

Speciation of Ruthenium as a Reduction Promoter of Silica-Supported Co Catalysts: A Time-Resolved in Situ XAS Investigation

Jingping Hong, Eric Marceau, Andrei Y. Khodakov, Lucia Gaberová, Anne Griboval-Constant, Jean-Sébastien Girardon, Camille La Fontaine, Valérie Briois

Complete reduction of the metal phase in cobalt-containing catalysts is often difficult to reach and can be promoted by a small amount of noble metals. Because these costly promoters are introduced in a very low quantity, their speciation and their chemical interaction with cobalt have seldom been…

Nature of vanadium species in V substituted zeolites: A combined experimental and theoretical study

M. Trejda, M. Ziolek, S. Dzwigaj, Frederik Tielens

The nature of vanadium species in V substituted zeolites is determined by combined experimental (XRD, FTIR, DR UV-vis) and theoretical (periodic DFT Calculations) Study. The introduction of V ions in lattice sites of SiBEA zeolite is evidenced by XRD and FTIR spectroscopy. The state of vanadium is…

Reactivity of gas-phase, crystal and supported V2O5 systems studied using density functional theory based reactivity indices

M. Calatayud, Frederik Tielens, F. de Proft

The existence of stable V2O5 compounds as gas-phase cluster, single crystal or as supported catalyst has motivated the present work aiming at characterizing the chemical reactivity of the different aggregated moieties. We apply the concepts of electrostatic potential and Fukui function, based on…

Low-energy electron induced resonant loss of aromaticity: consequences on cross-linking in terphenylthiol SAMs

L. Amiaud, J. Houplin, M. Bourdier, V. Humblot, R. Azria, C.-M. Pradier, A. Lafosse

Aromatic self-assembled monolayers (SAMs) can be used as negative tone electron resists in functional surface lithographic fabrication. A dense and resistant molecular network is obtained under electron irradiation through the formation of a cross-linked network. The elementary processes and…

What do vanadium framework sites look like in redox model silicate zeolites?

Frederik Tielens, Monica Calatayud, Stanislaw Dzwigaj, Michel Che

Ab initio periodic DFT Calculations on the structural and energy properties of different model vanadium framework sites in vanadium-substituted zeolites containing sodalite cavities are presented and related to experimental FTIR measurements on V containing SiBEA zeolite. The vanadium framework…

Exploring the reactivity of intraframework vanadium, niobium and tantalum sites in zeolitic materials using the molecular electrostatic potential

Frederik Tielens

The acid-base properties of group 5 zeolitic structures are discussed using the molecular electrostatic potential. The results point out that vanadium doped zeolites are less appropriate for electrophilic reactions, yielding minor basic character when they are compared with Nb or Ta doped zeolites…
