Rh Glycoprotein as an Ammonia Transport Molecule
… by one or more transport proteins in the Rh glycoprotein (RhxG) family. Longhorn sculpin (Myoxocephalus octodecemspinosus) cDNA was amplified using polymerase chain reaction (PCR) and then the PCR products were visualized on an agarose gel. The cDNA from the gel bands was then sequenced …

An SEGF study of the Rh(001) surface.
A self-consistent study of Rh(001) has been performed using the surface embedded Green function method. Calculations have been performed by embedding a three-layer slab onto a bulk rhodium substrate. The calculated work function and surface core level shifts are in good agreement with other …

Photochemische Reaktionen und Synthese heterotrimetallischer Verbindungen von Rh-Komplexen
Zur Darstellung der gewünschten trimetallischen Rh-Ti- und Rh-Zr-Komplexe mit verbrückten Tris(h5-cyclopentadienyl)silan-Liganden wurde eine neue Synthesestrategie entwickelt, wobei der verbrückende Ligand an einem monometallischen Precursor aufgebaut wird. Dafür wurden die Komplexe …

Catalytic activation of Rh,Pd nanoclusters supported on Ceria
Rh,Pd/CeO2 nanocatalysts exhibit excellent activity and stability for ethanol steam reforming (ESR) at 400°C. This thesis encompasses experimental and computational investigations of this nanocatalyst. The activation mechanism of Rh,Pd/CeO2 nanocatalysts under ethanol steam reforming conditions is …

Rh-Based Catalysis Chemistry of Aqueous-Phase Nitrogen Treatment Reactions
… The primary goal of this work is to investigate rhodium (Rh)-based catalysts for the remediation of inorganic nitrogen contaminants in water. This study addresses the effects of pH and salinity on the catalytic mechanism of nitrate/nitrite hydrogenation. A new support material for Rh was …

Nuclear magnetic resonance study of the Pt-Rh bimetallic clusters
We report the study of supported Pt-Rh bimetallic catalysts by 195Pt NMR and by 13C NMR of adsorbed CO. The metal particles are sA-soA in diameter. Study of the dependence of the 13CO resonance position as a function of Pt/Rh ratio and particle size shows that Rh is segregated to the surface. Study …

Distribution and biosynthesis of LH-RH and structurally related peptides
… of Luteinizing Hormone-Releasing Hormone (LH-RH) and structurally related peptides in mammalian tissues and tumours. Two strategies were employed in this investigation: (a) Immunological screening of tissues for suitable sources of LH-RH and the partial characterization of the LH-RH …

Synthesis and reactivity of Rh and Ir imino and azidophosphonamido complexes
This work reports a family of iminophosphonamido Rh and Ir cyclooctadiene (COD) complexes, [Ph2P(NR)2]M(COD), where the substituents on nitrogen vary, R = 2,4,6-trimethylphenyl (Mes) or adamantyl (Ad). The reaction chemistry of the iminophosphonamido Rh and Ir COD complexes was probed. This work …

A [(η5-Cp*)Rh]2+ kation komplexképző tulajdonsága L-Metioninnal és S-Metil-L-Ciszteinnel
A szakdolgozati munka során az (η5-Cp*)Rh]2+ kation komplexképző tulajdonságait vizsgáltam meg tridentát koordinációra képes L-metionin és S-metil-L-cisztein jelenlétében. Mindkét ligandum esetében (N, O, S) koordináció alakulhat ki, ahol a kén, kis bázicitású tioéter formában van jelen. Mivel már …
