The nano-domain, with short-range ordered structure, has been widely observed in rare-earth-doped ceria. Atomistic simulation has been employed to investigate the ordering structure of the nano-domain, as a result of aggregation and segregation of dopant cations and the associated oxygen vacancies in gadolinium-doped ceria. It is found that the binding energy of defect cluster increases as a fu...

An array of analytical methods including surface area determination by gas adsorption using the Brunauer, Emmett, Teller (BET) method, combustion analysis, XRD, ToF-SIMS, TEM and impedance spectroscopy has been used to investigate the interaction of gadolinia doped ceria (GDC) with hydrogen sulphide containing reducing atmospheres. It is shown that sulphur is incorporated into the GDC bulk and ...

The function of an RNA molecule is determined by its overall secondary and tertiary structure. The tertiary structure is facilitated and stabilized by the interaction with metal ions. The current chapter offers a detailed protocol on the use of the lanthanide metal ion terbium(III) as a powerful probe of RNA structure and metal-binding properties. When incubating RNA with low (micromolar) conce...

The quadruple complex formed by terbium with 4-chlorosalicylic acid (CSA), EDTA and cetyltrimethylammonium bromide (CTMAB) has been used for the sensitive spectrofluorometric determination of terbium in mixed rare earths. The effect of the experimental conditions on the fluorescence intensity was defined. Under the optimum conditions selected, the fluorescence intensity was linear with the terb...

Calretinin (CR) is a neuronal EF-hand protein previously characterized as a calcium (micromolar affinity) binding protein. CR-containing neurons are spared in some neurodegenerative diseases, although it is as yet unconfirmed how CR plays an active role in this protection. Higher levels of some metal cations (e.g. copper and zinc) are associated with these diseases. At the same time, metals suc...

A magneto-optic sensor is developed using a Terbium Doped Glass (TDG) element as a Faraday rotation sensor and optical fiber as light transmitting and receiving medium. Online LabView based application software is developed to process the sensor output. The system is used to sense the magnetic field of a DC motor field winding in industrial environment. The sensor output is compared with the ma...

Single-molecule magnets are a type of coordination compound that can retain magnetic information at low temperatures. Single-molecule magnets based on lanthanides have accounted for many important advances, including systems with very large energy barriers to reversal of the magnetization, and a di-terbium complex that displays magnetic hysteresis up to 14 K and shows strong coercivity. Ligand ...

A new terbium(III) complex with a (3,4-diphenyl)(2-methylthienyl)cyclopentadienyl ligand was synthesized. Single-crystal X-ray analysis revealed binuclear biscyclopentadienyl [TbCl2K]2 core. Luminescence properties of the terbium were analyzed.

In 2001, Bernstein, West and Gupta [i] described a possible campaign to monitor nuclear fission reactions over large distances using arrays of Super-Kamiokande (SuperK) type water Cherenkov detectors, modified to include neutron-capture elements such as gadolinium. This modification would allow sensitivity to reactor and other low energy antineutrinos through the inverse beta decay interaction....
