Studies with dithizone : the extraction of thallium (III)
Thallium(III) reacts with dithizone(I) in a complicated way through a number of intermediate products which depend on the relative proportions of reactants, the pH of the aqueous phase, the order of mixing of reactants, the time of phase equilibrium and the nature of the organic solvent used. The …

A Study of some Complexes of Thallium and Tellurium
… the complexes of heavy metals is stressed. The thallium (1) complexes with bipy,phen, thiovrea and substituted thioureas were prepared. The structure of the thallium {1} complexes with the nitrogen donor ligands is believed to be relatively undistorted. Some new complexes of thallium (I) with …

The syntheses and reactions of thallium and dithallium dicarbollides
… R¹R²=CH₃) species yielded some interesting thallium-containing heterocarboranes. The major pyrolysis products are thallium metal and TlR¹R²C₂B₉H₁₀. Hydrogen and the corresponding closo-carboranes, R¹R²C₂B₉H₉, were produced as minor products. The reactions of Tl₂R¹R²C₂B₉H₁₀ compounds with …

Thallium Isotope Implications for the Metalliferous Source of Carlin-type Deposits in northern Nevada
The Carlin-type deposits of northern Nevada comprise a world-class accumulation of Au deposits with a characteristic geochemical signature of elevated Tl, As, Hg, and Sb. Three possible sources of Au in Carlin-type systems have been described, and include: (1) leaching of Au from pre-enriched …

The lifetime and effective quenching cross section of the 6²P₃/₂ state of thallium
… the lifetime of the metastable 6²P₃/₂ state of thallium is discussed. Measurement of time varying optical absorption by time sampling techniques is explained for the study of the decay of the metastable atom concentration following a pulsed radio frequency discharge. The decay of the thallium …

A calorimetric study of the effects of surface energy in a type II superconductor
… measurements were made on lead, tin, lead-4at%thallium, and tin-6at% indium. The results confirm the existence and experted sign of the surface energy in a well annealed lead-4at%thallium sample, and indicate that the interphase surface energy in lead and tin is too small to be directly …
