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.

The stability of potassium-graphite deintercalation compounds

Carbon, 1996
We have synthesized K-GICs (potassium-graphite intercalation compounds) by the modified two-bulb method. The compounds were kept under a stabilization agent (liquid paraffin). The stage transition of K-GDICs (graphite deintercalation compounds), owing to the slow diffusion of water, was observed by X-ray diffraction measurements.

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-oxygen graphite intercalation compounds

Synthetic Metals, 1994
Abstract Intercalation of potassium superoxide KO 2 into graphite in the presence of potassium metal was studied. Graphite intercalation compounds of stage 1 (assigned formula C 4 KO 2 , c -axis repeat distance 8.44 A) and stage 2 (assigned formula C 8 KO 2 , c -axis repeat distance 11.75 A) were synthesized and isolated for the first time.

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 ...

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.
