The sintering of uranium monosulphide in presence of liquid phase

Materials Research Bulletin, 1972
Abstract Uranium monosulphide, doped with various amounts of UOS, and in certain cases with BaS, was sintered at temperatures 1500–1950°C in an argon atmosphere. The additions of both UOS and BaS result in the formation of liquid phase, which was determined to be an US-UOS or US-BaUS2 eutectic respectively.

SOME OBSERVATIONS ON THE STRUCTURE OF ETHYLENETHIURAM MONOSULPHIDE

Canadian Journal of Chemistry, 1960
An attempt has been made to answer several apparent objections to the structure ethylene-thiuram monosulphide assigned to the monomeric material of formula C4H6N2S3 obtained by air oxidation of disodium ethylenebisdithiocarbamate. Comparison of the ultraviolet and infrared absorption spectra, potentiometric titrations, and biological assays of the ...

A note on the effects of tetramethylthiuram monosulphide on radical polymerizations

European Polymer Journal, 1969
Abstract A report is given of effects of tetramethylthiuram monosulphide (TMTM) upon the polymerization of styrene at 80°; it can act as both an initiator and a retarder and there is great sensitivity to light. Experiments with 14 C-TMTM show that transfer to initiator is important.

Isotope shift studies in the spectrum of boron monosulphide

Pramana, 1987
The spectrum of boron monosulphide has been excited in microwave discharge and photographed at moderate dispersion. TheC 2Π r −X 2Σ+,B 2Σ+−A 2Π i andA 2Π i −X 2Σ+ band systems extending from 2100–9000 A have been obtained for B32S and B34S species. Isotope shifts for all these band systems have been measured.

Elastic constants of single crystal uranium monosulphide

Journal of Applied Physics, 1979
Measurements are reported for the temperature dependence of the single crystal elastic constants C11 and C44 of US in its para- and ferromagnetic regions. A softening of C11 sets in from approximately 20 K above Tc to exhibit a minimum at Tc. The shear constant C44 undergoes a softening over the entire paramagnetic region to reach a maximum change of ...

Thermoelectric Phenomena in Gallium Monosulphide Single Crystals

Crystal Research and Technology, 1992
AbstractMeasurements of thermoelectric power of GaS single crystals grown by melt growth technique, were performed in the range of 150 K to 500 K. Investigations of GaS compound have revealed that it has interesting properties. Many physical parameters were determined such as carriers mobilities, effective masses of free charge carriers, diffusion ...

High-temperature thermodynamic properties of uranium monosulphide

Journal of Inorganic and Nuclear Chemistry, 1971
Abstract The enthalpy of uranium monosulphide has been measured from 400 to 1400 K in an adiabatic drop calorimeter. The data are represented by the equation (HT-H298·15) = 12·633T + 7·7865 × 10−4T2 + 9·0413 × 104T−1 – 4139 cal mole−1 with a mean deviation of 0·55 per cent.

SPECTRUM AND STRUCTURE OF THE BORON MONOSULPHIDE (BS) MOLECULE

Canadian Journal of Physics, 1951
Two band systems of the BS molecule, called the α and γ systems, have been excited in a discharge through B2S3 vapor in a quartz discharge tube. Vibrational and rotational analyses of these systems have been carried out, and it is shown that both systems have the same lower state, which is a 2Σ state. Both the upper states are 2Π states.
