Coprecipitation with terbium hydroxide quantitatively recovered trace amounts of chromium(III), copper(II) and lead(II) at pH 8.4 - 10.8, 8.0 - 11.5 and 8.7 - 11.5, respectively. The precipitate was dissolved in 0.85 mol dm(-3) nitric acid, and the analytes were determined by graphite-furnace atomic absorption spectrometry (GF-AAS). The presence of terbium (up to 7 g dm(-3)) did not interfere w...

Four salts containing imidazolium cations and europium(III)- or terbium(III)-centered complex anions have been successfully synthesized from an ethanol/H2O solution. The single-crystal X-ray diffraction analyses reveal that these compounds have a common formula of [R][Ln(DETCAP)4] [R = 1-ethyl-3-methylimidazolium (C2mim), Ln = Eu (1) and Tb (2); R = 1-butyl-3-methylimidazolium (C4mim), Ln = Eu ...

We report a low-temperature scanning tunneling microscopy and spectroscopy study of the structural and electronic properties of a bilayer of terbium double-decker (bis(phthalocyaninato)terbium(III), TbPc2) molecules on Au(111) at 5 K. The TbPc2 molecules are found to adsorb flat on top of a first compact TbPc2 monolayer on Au(111), forming a square-like packing similar to the underlying first l...

A terbium(III) complex gives off strong luminescence upon reacting with human serum albumin in aqueous solution, which can be used to detect the presence and structural modifications of this protein.

A terbium(III) complex exhibits efficient selectivity for proximal diphosphorylation of peptides, accompanied with remarkable luminescence enhancement in the presence of Zn(II) ions in both buffer and protein extraction solutions from brain homogenates of mice.

Abstract The molar heat capacity of terbium hafnate with a pyrochlore structure was measured by relaxation and adiabatic calorimetry. smoothed values the were used to calculate thermodynamic functions in temperature range 6–330 K. general form Schottky anomaly determined.

OBJECTIVES With regard to pharmacological effects of carvacrol on the respiratory system, its effect on cytokines genes expression in splenocytes of asthmatic mice was examined in this study. MATERIALS AND METHODS Splenocytes were isolated from non-sensitized (control group), sensitized mice to ovalbumin (OVA) (group S), and S animals treated with dexamethasone, and three concentrations of ca...

A process aimed at the recovery of terbium from liquid solutions using activated carbon (AC) derived spent coffee grounds (SCG) was assessed. AC obtained hydro-alcoholic treatment SCG, followed by physical activation as-obtained product. The exhibited both microporous and mesoporous structures, which were shown corresponding nitrogen adsorption–desorption isotherms scanning electron microscopy ...

Resonant Bragg diffraction of soft, circularly polarized x-rays has been used to observe directly the temperature dependence of chiral-order melting in a motif of Mn ions in terbium manganate. The underlying mechanism uses the b-axis component of a cycloid, which vanishes outside the polar phase. Melting is witnessed by the first and second harmonics of a cycloid, and we explain why the observe...
