Bis(3,4-diphenyl)(2-methythienyl)cyclopentadienyl Terbium Chloride

Density of Molten Terbium Chloride

Anhydrous (99.99%) TbCl3 was obtained from Aldrich (Milwaukee, WI, USA) and used without further purifications. It was handled in an argon-filled dry box with a water content < 2 ppm and an oxygen content < 1 ppm. A 166Ho radiation source (2.27 MBq) was used because of its desirable decay characteristics (t1/2 = 1200y, up to 8 photons per disintegration, more than 10% branching ratio). A multi-...

Mechanoluminescence studies of gamma irradiated potessium chloride single crystals and microcrystalline powder doped with terbium

This paper reports the mechanoluminescence (ML) induced by impulsive excitation of γ irradiated terbium doped KCl single crystals and powder. The KCl crystals having different concentrations of terbium were prepared by melt technique (slow cooling).The crystals of small sizes were cleaved from grown crystal block and crushed to obtain powder or microcrystalline powder. The annealed samples were...

Terbium modulation of single gamma-aminobutyric acid-activated chloride channels in rat dorsal root ganglion neurons.

We have previously reported that lanthanides markedly potentiate the GABA-induced chloride current by acting at a distinct site on the GABAA receptor-channel complex (Ma and Narahashi, 1993a,b). These studies have now been extended to the single-channel level and changes in gating kinetics of GABAA receptor currents caused by 100 microM terbium (Tb3+) are reported. The GABA-induced currents wer...

Sodium terbium(III) polyphosphate

Single crystals of the title compound, NaTb(PO(3))(4), were obtained by solid-state reaction. This compound belongs to type II of long-chain polyphosphates with the general formula A(I)B(III)(PO(3))(4). It is isotypic with the NaNd(PO(3))(4) and NaEr(PO(3))(4) homologues. The crystal structure is built up of infinite crenelated chains of corner-sharing PO(4) tetra-hedra with a repeating unit of...
