TL;DR: In this paper, the electrical conductivity, thermoelectric power, magnetic susceptibility, and molar volume of liquid Cs-Sb alloys and, partly, NaSb and KSb are reported.
Abstract: Abstract The paper reports new measurements of the electrical conductivity, thermoelectric power, magnetic susceptibility, and molar volume of liquid Cs-Sb alloys and, partly, Na-Sb and K-Sb alloys. From the temperature and composition dependence of the electronic properties it is concluded that typical semiconducting behavior similar to liquid chalgogen based alloy semiconductors exists over a wide composition range. The change in bonding for 0.25≦XSb≦0.5 is qualitatively discussed and it is found that these liquid alloys are not essentially ionic in character.

TL;DR: In this article, a radiochemical neutron activation analysis technique was developed for the determination of traces of platinum in environmental and geological samples via the indicator radionuclide 199Au, based on the separation of gold on polyurethane foam from 1 M HCl.

TL;DR: In this paper, the analyte element in a molecular form during volatilisation of the matrix or, in general, during pre-atomisation treatment steps are found to be dominant when antimony and nickel chloride are mixed.
Abstract: Analyte and interferent are volatilised from separated spots of a L'vov platform with two cavities. The results obtained give a deeper insight into the mechanisms of interferences observed in a graphite tube furnace. Losses of the analyte element in a molecular form during volatilisation of the matrix or, in general, during pre-atomisation treatment steps are found to be dominant when antimony and nickel chloride are mixed. Pronounced interactions between the gas phase and the condensed phase are observed, however, when the analyte and interferent are separated on the dual cavity platform. Essentially, all interferences disappear when nickel in nitric acid is used as a matrix modifier and proper conditions are selected. The absence of any gas-phase interactions allows the conclusion that near thermal equilibrium is obtained under these conditions. The characteristic mass found for antimony was typically between 25 and 30 pg per 0.0044 A s.
