CO2 reduction over noble metal/carbon nanotube catalyst
Carbon nanotube-based Pt/Pd and Ru catalysts, independently synthesized by a microwave reaction technique, show good catalytic activity for CO2 reduction in the contexts of dry reforming (DR) of methane (CH_4 + CO_2 -> 2CO + 2H_2) and reverse water gas shift (RWGS) (H2 + CO_2 -> CO + H_2O). …

Fabrication, characterisation, and analysis of plasmonic noble metal nanostructures
Plasmonic nanostructures have potential applications across a diverse range of fields, from biosensing to solar energy. The coupling of electric fields to oscillating free- electrons on the surface of a material create plasmonic resonances, which are the key to concentrating and utilising light …

Noble gases: a record of the early solar system
"Analyses of the noble gases in samples of iron meteorites are presented which indicate the following: 1. The inclusions of iron meteorites contain noble gases with a wide range of isotopic compositions. 2. The noble gas concentration and isotopic anomalies arc often grossly inhomogeneously …

Noble Farmers: The Provincial Landowner in the Russian Cultural Imagination
… need to provide normative models for the Russian nobleman's domestic life and self, following the 1762 Manifesto that freed the gentry from obligatory state service. The material suggests that a prominent strain in the Russian novelistic tradition that took the provincial landowner as a central …

Noble-metal quantum well structures: A theoretical and experimental study
Currently, there is a great deal of interest in metallic multilayer systems, in particular magnetic multilayer structures, for both technological and scientific reasons. Since the growth properties and band structures for these systems are, in general, quite complicated, most current research is …

Engineering carbide nanoparticles coated with noble metal monolayers for catalysis
The noble metals (NMs) comprise ruthenium (Ru), rhodium (Rh), palladium (Pd), silver (Ag), osmium (Os), iridium (Ir), platinum (Pt), and gold (Au). Together, these corrosion-resistant elements serve as nature's universal catalysts by binding reactant molecules neither too strongly nor too weakly. …

Aristocrats into Modernity: French Émigrés and the Refashioning of Noble Identities
… wake of the French Revolution, several thousand noble men and women sought refuge outside France. The emigration was a unique space in which ci-devants – as the revolutionaries called ex-nobles – could experiment with different practices and conceptions of nobility. The collapse of the …

Quantum mechanical origin of the plasmonic properties of noble metal nanoparticles
Small silver and gold clusters (less than 2 nm) display a discrete absorption spectrum characteristic of molecular systems whereas larger particles display a strong, broad absorption band in the visible. The latter feature is due to the surface plasmon resonance, which is commonly explained by the …
