Potassium Hydroxylamine Complexes

Inorganic Chemistry, 2008
Potassium complexes of N,N-dialkylhydroxylamines [KONR2, R=Me (1a), iPr (2a), CH2C6H5] were synthesized by the deprotonation of the corresponding N, N-dialkylhydroxylamines with KH. 1a and 1b [(KONMe2)(HONMe2)] dissolve in THF under the addition of an additional equiv of the parent hydroxylamine to give 1b and [(KONiPr2)(HONiPr2)(THF)] 2b. 1b, 2b and [(

Potassium physiology

The American Journal of Medicine, 1986
Potassium is the most abundant exchangeable cation in the body. It exists predominantly in the intracellular fluid at concentrations of 140 to 150 meq/liter and in the extracellular fluid at concentrations of 3.5 to 5 meq/liter. The maintenance of the serum potassium concentration is a complex bodily function and results from the balance between intake,

Facile Fabrication of Nitrogen‐Doped Porous Carbon as Superior Anode Material for Potassium‐Ion Batteries

Advanced Energy Materials, 2018
Potassium‐ion batteries (PIBs), using carbon materials as the anode, are regarded as a promising alternative to lithium‐ion batteries owing to the feasible formation of stage‐1 potassium intercalation compounds (KC8).

Potassium supplements or potassium‐sparing agents

Acta Pharmacologica et Toxicologica, 1984
Abstract:During diuretic treatment alterations in myocardial cellular excitability due to potassium‐induced dis‐turbances of the membrane potential may arise without obvious changes of total body K. This may be explained by coexisting disturbances of the acid/ base balance and other ions such as magnesium.

Potassium Citrate and Potassium Gluconate Versus Potassium Chloride

JAMA, 1967
IN LATE 1964 a sudden increase in the occurrence of circumferential ulcerating, stenosing lesions of the small bowel was noted both in Europe and the United States. Lindholmer et al 1 in Sweden and Baker et al 2 in this country first suggested the association of these lesions with enteri-coated thiazide diuretic potassium chloride preparations ...
