Implementing Multi-Electron Transfer Strategies in Uranium Chemistry
In the last decades, the activation of small molecules has attracted increasing attention for their use as cheap and abundant feedstock. Low-oxidation state uranium complexes have displayed high reactivity towards small molecules thanks to their unique pro ...
EPFL2023Photo-induced dynamics of the heme centers in cytochrome bc(1)
Majed Chergui, Frank van Mourik, Andre Al Haddad, Adrien Alexis Paul Chauvet
The ultrafast response of cytochrome bc1 is investigated for the first time, via transient absorption spectroscopy. The distinct redox potentials of both c(1)- and b-hemes allow for a clear differentiation of their respective signals. We find that while th ...
Royal Society of Chemistry2015Iron Complexes for Hydrogen Activation and Catalytic Hydrogenation
Inspired by Nature several groups have developed structural and functional iron complexes mimicking the active site of the iron-hydrogenases, which show high reactivity in the H2 cleavage. Usually pendant bases have been incorporated onto families of Fe co ...
EPFL2015Transient response method for characterization of active sites in HZSM-5 with low content of iron during N2O decomposition
The surface active Fe-sites in HZSM-5 with low content of iron (
2004Time-resolved visible and infrared study of the Cyano complexes of Myoglobin and of Hemoglobin I from Lucina pectinata
Majed Chergui, Frank van Mourik, Alejandro Gonzalez Gonzalez, Luigi Bonacina
The dynamics of the ferric CN complexes of the heme proteins Myoglobin and Hb I from the clam Lucina pectinata upon Soret band excitation is monitored using IR and broad band visible pump-probe spectroscopy. The transient response in the UV-vis spectral re ...
2004Ultrafast structural dynamics in electronically excited many-body systems
This thesis reports on results of three different experiments of photo-induced structural dynamics in the condensed phase, investigated by time-resolved pump-probe spectroscopy with femtosecond time-resolution. In the first part, we address the ultrafast d ...
EPFL2004Active Sites in HZSM-5 with Low Fe-content for the Formation of Surface Oxygen by Decomposing N2O: Is Every Deposited Oxygen Active?
Surface-active centers were detected in HZSM-5 with a low content of iron (
2003Investigation of the carbon monoxide and oxy hemoglobin I complexes from Lucina pectinata by femtosecond transient absorption
Hb I (HbI) is an invertebrate monomeric hemeprotein from Lucina pectinata that contains 142 amino acid residues. The HbI heme pocket structural compn. shows an arrangement of phenylalanyl residues (Phe (29), Phe (43) and Phe (68)) that has not been obsd. i ...
2002Catalytic Fe3+ clusters and complexes in Nafion active in photo-Fenton processes. High-resolution electron microscopy and femtosecond studies
Philippe Buffat, Juan Kiwi, Elena Suvorova Buffat
This study presents the detailed nature of iron clusters formed on Fe3+-Nafion membranes. The catalytic nature of these clusters during immobilized Fenton processes was observed to be a function of the deposition method of Fe ions on the Nafion. The nonbio ...
2002Study of the structural and dynamical properties of a biomimetic compound of diiron proteins via ab initio and hybrid molecular dynamics simulations
A biomimetic four-helix bundle with a binuclear active site (DF1), bearing Zn, Mn or Fe as transition metals, has been synthesized and characterized. The carboxylate bridged binuclear motif of DF1 resembles the active site of numerous binuclear enzymes, su ...
