Eksempler på brug af CATIONS i en sætning

• It may be described as the sharing of free electrons among a structure of positively charged ions (cations).
• In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively charged ions (cations) and negatively charged ions (anions), which results in a compound with no net electric charge (electrically neutral).
• Upon dissolving, the substance separates into cations and anions, which disperse uniformly throughout the solvent.
• Electroplating, also known as electrochemical deposition or electrodeposition, is a process for producing a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current.
• 63 g, but calcium (Ca) can substitute for up to 27% of the strontium (Sr) cations, and barium (Ba) up to 3.
• Electroplating, a process that uses electric current to reduce dissolved metal cations so that they form a coherent metal coating on an electrode.
• In this context, leaving groups are generally anions or neutral species, departing from neutral or cationic substrates, respectively, though in rare cases, cations leaving from a dicationic substrate are also known.
• Activation of NMDA receptors results in the opening of the ion channel that is nonselective to cations, with a combined reversal potential near 0 mV.
• Polymeric uranium(VI) fluorides containing organic cations have been isolated and characterized by X-ray diffraction.
• It has been proposed that the platinum fluoride forms a negatively charged polymeric network with xenon or xenon fluoride cations held in its interstices.
• These hydrogen ions displace cations attached to negatively charged soil particles so that the cations are available for uptake by the root.
• In DNA replication, for example, formation of the phosphodiester bonds is catalyzed by a DNA polymerase enzyme, using a pair of magnesium cations and other supporting structures.
• Due to the stability of sulfonate anions, the cations of sulfonate salts such as scandium triflate have application as Lewis acids.
• Stilbite shows a wide variation in exchangeable cations: silicon and aluminium ions occupy equivalent sites and can substitute for each other.
• Because these cations were able to be stabilized, scientists could now use infrared spectroscopy and nuclear magnetic resonance (NMR) spectroscopy to study them in greater depth, as well as use them as catalysts in organic synthesis reactions.
• The rule can be used to understand the stability of completely conjugated monocyclic hydrocarbons (known as annulenes) as well as their cations and anions.
• An example is a transition in which the relative structure of the anionic array is unaltered but the cations reorganize as in:.
• Upon hydration, Nafion phase-separates at nanometer length scales resulting in formation of an interconnected network of hydrophilic domains which allow movement of water and cations, but the membranes do not conduct electrons and minimally conduct anions due to permselectivity (charge-based exclusion).
• Typical pharmacophore features include hydrophobic centroids, aromatic rings, hydrogen bond acceptors or donors, cations, and anions.
• The original product consisted of powdered sodium hexametaphosphate (amorphous sodium polyphosphate), which, in water, would complex with ambient calcium ions and certain other cations—preventing formation of unwanted salts and interference by those cations with the actions of soap or other detergents.
