Absorption Spectra of Terbium Perchlorate and Terbium Chloride Solutions

Analytical Chemistry, 1958
The spectra of terbium perchlorate and terbium chloride solutions have been recorded in the range of 200 to 1200 m mu with the Cary recording spectrophotometer. An intense absorption at 219.8 m mu follows Reer's law and is usable for accurate determination of terbium at low concentrations.

Alloys of cerium with neodymium, samarium and terbium, and of praseodymium with terbium

Journal of the Less Common Metals, 1968
Abstract The lattice spacings of a selection of alloys in the systems Ce-Nd, Ce-Sm, Ce-Tb and Pr-Tb, have been determined. For the Ce-Nd, Ce-Tb and Pr-Tb systems, the room-temperature magnetic susceptibilities of certain alloys have been determined. Extrapolation of the atomic volume/composition plots of alloys with the double hexagonal structure in ...

Some Magnetic Structure Properties of Terbium and of Terbium-Yttrium Alloys

Journal of Applied Physics, 1963
Neutron diffraction studies have been made on single-crystal and polycrystalline specimens of terbium. Earlier magnetic and thermal measurements have indicated a transformation to an ordered magnetic state at approximately 230°K, and a subsequent order-order transformation at approximately 220°K.

Terbium replacement of calcium in parvalbumin

Journal of Molecular Biology, 1978
Abstract Carp muscle calcium binding parvalbumin, crystallized in 2.9 m -ammonium sulfate, can bind two Tb3+ ions, which displace the two Ca2+ ions normally present. The Ca2+ co-ordinated in the loop between the E and the F α-helices is displaced at low Tb3+ concentrations; whereas the Ca2+ at the CD site is replaced only at higher Tb3 ...

Terbium chelates for fluorescence immunoassay

The Analyst, 1985
A series of aromatic derivatives of diethylenetriaminepentaacetic acid has been prepared and the fluorescence properties of the terbium chelates examined. Most of the chelates show low fluorescence intensity, but have long fluorescence lifetimes.

Aging in the ferromagnetic phase of terbium

Journal of Physics: Condensed Matter, 2012
We report on aging, rejuvenation and memory effects in the ferromagnetic phase of pure terbium. We have applied an experimental method specifically for investigating slow dynamics of spin glasses, because these effects cannot be interpreted as conventional diffusion after-effects.

Measurement of binding of terbium to DNA

Bioinorganic Chemistry, 1978
This communication demonstrates further that terbium(III) can be used as a probe for DNA. The stoichiometry of terbium binding to DNA was measured by two new methods. In the first method, calf-thymus DNA was titrated with radioactive terbium-160, which is an isotope of the common terbium-159.

Specific heat of holmium and terbium

Physica Status Solidi (a), 1979
The lattice heat capacity of holmium and terbium is calculated using the frequency distribution function obtained from a lattice dynamical model for h.c.p. metals based on Keating's approach. The magnetic contribution to the specific heat of these rare earth metals is evaluated by subtracting the lattice and electronic contributions from the Cv data of

Interaction of terbium with human platelets

Biochemical and Biophysical Research Communications, 1984
The effect of terbium on platelets has been studied by aggregation experiments and by fluorescence measurements. TbCl3 does not substitute for CaCl2 in the aggregation of platelets induced by ADP, but it may even inhibit, probably by a competition mechanism.

Bright Terbium Chelate Phosphors

Applied Optics, 1968
Radiative quantum efficiencies can be enhanced by a factor of up to ten in solid films of terbium chelate phosphors by coordination with a tripyrazolylborate adduct. The data obtained point to a shielding of the terbium ion from low frequency vibrations of the solid state resin environment.
