Interstitial Compounds of Potassium with Carbon Fibres

Nature, 1968
THE formation of interstitial compounds of potassium in graphite is well known and the phases C8K, C10K, C24K, C36K and others have been identified and their physical and chemical properties measured by several authors1–9.

Production of potassium depletion by benzothiadiazine compounds∗

The American Journal of Cardiology, 1962
Abstract Secondary hyperaldosteronism was simulated in seven patients by the administration of desoxycorticosterone acetate (DCA) in doses of 30 mg. per day. In these patients the sodium-retaining properties of this agent appeared to be independent of total exchangeable sodium.

Reduction of aromatic compounds by potassium-graphite intercalation compounds

Carbon, 1979
Abstract The interaction is investigated between aromatic compounds (polynuclear hydrocarbons, aryl substituted ethenes, hydrocarbons with a mobile hydrogen atom, aromatic nitriles and ketones) and the binary potassium-graphite intercalation compound-KC 24 -in solvating solvents (tetrahydrofuran or dimethoxyethane).

Potassium under Pressure: A Pseudobinary Ionic Compound

Physical Review Letters, 2009
Experimentally, we have found that among the "complicated" phases of potassium at intermediate pressures is one which has the same space group as the double hexagonal-close-packed structure, although its atomic coordination is completely different.

Toxicology of potassium channel-directed compounds in mosquitoes

NeuroToxicology, 2017
Potential targets for new vector control insecticides are nerve and muscle potassium channels. In this study, the activities of known potassium channel blockers (4-aminopyridine, quinidine, and tetraethylammonium) and the insecticide propoxur were compared to three experimental catechols and several other compounds against Anopheles gambiae and Aedes ...

Potassium Concentration Dependence of the Superconductivity in the Potassium Graphite Intercalation Compounds

Journal of the Physical Society of Japan, 1981
Magnetic susceptibilities have been measured at temperatures down to 60 mK by AC Hartshorn bridge method for the potassium graphite intercalation compounds with several compositions (C 8.0 K ∼C 21.6 K) prepared by the use of HOPG. T c is nearly constant to be ∼150 mK for C 8.0 K ∼C 14.7 K, while no transition is found down to 60 mK for C 16.7 K and C ...

Reaction of Ammonia with Graphite-Potassium Compounds

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1994
Reaction of ammonia vapor with a KC 8 GIC and treatment (vacuum and heating) produces a new second stage GIC: K(NH 3 ) 0.5 C 8 with di=815 pm. The stage 1 GIC can be obtained by reaction with potassium vapor. Similar treatment with KC 24 leads to a stage 2 GIC:K(NH 3 ) 1.3 C 24 with a smaller di=648 pm.

M2U4O12 compounds of potassium, rubidium and thallium

Journal of Nuclear Materials, 1988
Solid state reactions of M2CO3 (M = K, Rb and Tl) and UO2 with M/U = 0.5 were studied in air and in inert atmosphere at about 900°C. X-ray diffraction studies show that (1) M2U4O13 compounds are formed when the reaction mixture is heated in air and (2) MUO3 phases are obtained in inert atmosphere.
