Ferritic/martensitic steels considered as first-wall candidate materials for fusion reactors experience significant radiation hardening at temperatures below similar to400 degreesC. Experimental evidence suggests that the observed defects are large interst ...
Cytochrome c6A is a unique dithio-cytochrome of green algae and plants. It has a very similar core structure to that of bacterial and algal cytochromes c6 but is unable to fulfill the same function of transferring electrons from cytochrome f to photosystem ...
The control of cellular iron homeostasis involves the coordinate post-transcriptional regulation of ferritin mRNA translation and transferring receptor mRNA stability. These regulatory events are mediated by a soluble cytoplasmic protein, iron regulatory f ...
The heterogeneous photoinduced electron transfer involving dyes adsorbed at the interface between two immiscible electrolyte solutions and redox molecules located in the adjacent phase manifests itself as photocurrent responses under potentiostatic conditi ...
Dimensionally Stable Anodes (DSA®) are electrodes composed of a metal support and an oxide coating (catalyst). Particularly in this thesis, the Ti/IrO2 electrode was used for the study of the fraction of the surface which participates effectively in the in ...
Enzymes possessing the capacity to oxidize molecular hydrogen have developed convergently three class of enzymes leading to: [FeFe]-, [NiFe]-, and [FeS]-cluster-free hydrogenases. They differ in the composition and the structure of the active site metal ce ...
Carbon-13 solid-state NMR is used to determine, via the temperature dependence of paramagnetic shifts, the spin ladder of magnetic levels and the related spin exchange parameters in 4Fe-4S clusters. This study has been carried out between 180 and 330 ...
The process of ferredoxin reduction by photosystem I has been extensively investigated by flash-absorption spectroscopy in psaD and psaE deleted mutants from Synechocystis sp. PCC 6803. In both mutants, the dissociation constant for the photosystem I/ferre ...
The goal of our work was the synthesis and studies on the reactivity and intramolecular dynamics of new classes of mixed clusters of the type Ir3Rh(CO)12. In total 17 derivatives of this compound have been synthesized, with ligands such as halogenides, mon ...
The voltage induced assembly and photoreactivity of cadmium selenide (CdSe) nanoparticles protected by mercaptosuccinic acid are studied at the polarisable interface between water and 1,2-dichloroethane electrolyte solutions. Cyclic voltammograms and admit ...
