Anodic dissolution of zinc in potassium iodide-potassium iodate solutions
"The anodic dissolution of Zn was studied in KI-KIO₃ solutions at 25ºC. In I⁻ solutions, it was found that the apparent valence of Zn ions going into solution is approximately two. Smaller values are obtained in IO₃⁻ solutions, with the most pronounced changes occurring in the higher …

Potassium-Argon Dating
… used to determine the age of a mineral. Because potassium exists almost everywhere this gives us a valuable method for dating rocks. The developments, improvements, procedures, suitable minerals and accuracy of the K-A dating method, are analyzed in this paper. </p>

Ultraviolet and visible absorption spectra of potassium and potassium-xenon mixtures
The visible absorption spectrum of the potassium dimer has been studied using a new type of optical cell designed specifically for the alkali vapors or alkali-rare gas mixtures. Particular emphasis has been placed on examining the diffuse K2 bands lying at 722 nm, 575 nm, 478 nm and 402 nm. …

Potassium in young children
Potassium i.s one of the major constituents of the human body but its role in metabolism is not clearly defined. One reason for this is the predominant intracellular distribution of the ion and the attendant difficulties in the detection of deficiency states. Serum potassium levels are of little …

Trafficking motifs in potassium channels
The pancreatic ATP-sensitive potassium (KATP) channels couple glucose metabolism to excitability of the pancreatic β-cells to regulate insulin secretion. The channel subunits, Kir6.2 and SUR1, are encoded by the KCNJ11 and ABCC8 genes respectively. Genetic polymorphisms in these genes, which reduce …

Potassium-free and potassium-containing electrolytes affect plasma ions and acid-base status of endurance horses
Effects of potassium supplementation were evaluated in four studies in endurance horses during races and treadmill exercise. In the first and second studies a potassium-free experimental formula was compared to potassium rich commercial formulas. The first study showed that supplementation …

Voltage-Gating Mechanism in Potassium Channels
"Voltage-gated potassium channels are membrane proteins that regulate the flow of K+ ions across the cell membrane. These channels respond to changes in electrostatic potential across the cell membrane, and allow passage of K+ ions through their conduction pore. In excitable cells, an interplay of …
