TL;DR: In this paper, the effects of various pretreatments on total area, oxygen chemisorption, and S Mo ratio have been studied on unsupported molybdenum sulfide, prepared by in situ decomposition of ammonium tetrathiomolybdate (ATTM) in helium.

TL;DR: In this paper, a polypyrrole-tetrathiomolybdate anions and molybdenum trisulfide were prepared on platinum and tin oxide coated glass electrodes by anodic electrochemical deposition from an aqueous solution containing pyrrole and ammonium tetrathio-bdate.

TL;DR: Intravenous administration of ammonium tetrathiomolybdate appeared to be an effective means of containing the acute phase of copper toxicity in sheep, whether this arose from continuous ingestion of high copper feeds or by injudicious use of copper preparations for the control of copper deficiency.
Abstract: Intravenous administration of ammonium tetrathiomolybdate (three doses on alternate days) appeared to be an effective means of containing the acute phase of copper toxicity in sheep, whether this arose from continuous ingestion of high copper feeds or by injudicious use of copper preparations for the control of copper deficiency. No adverse effects were recorded on lamb numbers, birth weight or survival of lambs born to ewes of normal to low copper status when the treatment was applied at sensitive periods of the reproductive cycle. Decreases in 'available' plasma copper and in liver damage occurred rapidly in response to intravenous tetrathiomolybdate and it is suggested that all animals at risk be treated.

TL;DR: Effective control of copper poisoning in sheep was obtained by the subcutaneous injection of ammonium tetrathiomolybdate by causing a substantial reduction in liver copper content and in liver damage and decreased the mortality rate in animals that had developed the haemolytic crisis.
Abstract: Effective control of copper poisoning in sheep was obtained by the subcutaneous injection of ammonium tetrathiomolybdate. Three doses, each of 3.4 mg/kg bodyweight, were given on alternate days. This treatment caused a substantial reduction in liver copper content and in liver damage. It also decreased the mortality rate in animals that had developed the haemolytic crisis. The subcutaneous route is as effective as the intravenous route and is more convenient. No adverse side-effects of the treatment were observed.

TL;DR: In this article, a self-supporting molybdenum sulfide sample with high surface area was prepared by in situ thermal decomposition in vacuum of ammonium thiomolybdate.
Abstract: Self-supporting molybdenum sulfide samples with high surface area were prepared by in situ thermal decomposition in vacuum of ammonium thiomolybdate. BET specific surface area of the resulting material has its highest values of about 120 m 2 /g for samples treated in situ at 473 K and decreases on further heating, while the composition of samples treated at 423–473 K is close to MoS 3 , and after heating up to 573 K corresponds to MoS 2 . FTIR spectra show that precursor decomposition is almost completed already after treatment at 423 K, although the sample still contains admixed ammonium ions. After 473 K most of contaminations are gone. Spectra of adsorbed NH 3 , ND 3 , CO, SO 2 , CO 2 , COS and CH 3 SH adsorbed on samples pretreated at 423–473 K are very close to those obtained for air-contacted MoS 2 powder. However higher band intensities and the use of labeled compound enabled us to identify the bands of coordinately bonded NH 3 molecules and to point to the existence of acidic sites capable to protonate ammonia. Molecularly adsorbed CH 3 SH could be distinguished from its dissociative form; this reveals the existence of acid–base pair sites on bulk molybdenum sulfide.
