Crystal and molecular structure of bis(hippurate)bis(imidazole)copper(II) square-planar coordinated via two centrosymmetric imidazole nitrogens and carboxylic oxygens; two weak interactions (2.736 (4) Å) with uncoordinated carboxylic oxygens in the "out-of-plane" positions complete the coordination...
Addition of oxygen to iron precovered with potassium causes at first a further lowering of the work function (to a minimum value) and thermally stabilizes the adlayer but simultaneously the sticking coefficient for nitrogen is lowered due to blocking of adsorption sites by oxygen. This latter ...
The main elements of this compound are potassium K, chromium Cr, and oxygen O. {eq}K_2Cr_2O_7 {/eq} is the potassium dichromate formula. This chemical compound is a salt, it is made from the bonding metal cations, potassium ({eq}K^+ {/eq}), with nonmetal anions, dichromate ({...

G. Scott Lett, in Progress in Biophysics and Molecular Biology, 2006 The preclinical data obtained for COMPOUND A and COMPOUND B showed strong evidence that these drugs may not only block the delayed rectifier potassium current (IKr), but are also likely to interact with the sodium (INa) and...
It is used as a fluorinating agent for fluorinated organic compounds, which could be applied as finishing agent for fabrics, components of extinguishing agents, electroplating bathes, lubricating oils, oxygen carriers in blood substitutes. For example, potassium hydrogen fluoride is used as fluori...
Potassium oxide, also known as Potassium Monoxide, Di-potassium Hydroxide, and Kalium Oxide, is an ionic compound resulting from the combination of potassium and oxygen. Due to its high reactivity, po.. Will potassium oxide reduce the uptake of sodium as much as potassium nitrate? Nov 21 2021...
An improved electrode for use in oxygen determination is disclosed. Interference from carbon dioxide is eliminated by combining an improved electrolyte with means for permitting rapid electrolyte movement into and out of the space between the cathode and the membrane covering the cathode to maintain the...
s etchant, which is useful for metallographers to provide contrast between binder and carbide phases in cemented carbides. Further, it is used in many amperometric biosensors as an electron transfer agent replacing an enzyme's natural electron transfer agent such as oxygen with the enzyme glucose...
