cation

When an organic molecule like electron donating pyridine adsorbs on the surface, cations get reduced due to charge transfer.

Ionosphere is the height of the gas, solar radiation, ionization with a charge of anions and cations, and some form of electronic freedom.

Ionic liquid is also known as room temperature molten salts, which consists of nitrogen-containing organic cations and inorganic anions.

For ionic compounds , the state of having exactly the ratio of cations to anions specified by the chemical formula .

The residual negative charge is balanced by cations between the chains which also serve to hold the chains together.

The cations were transported out of the soil and captured in the ion exchange medium.

the rejection of the membrane to divalent cations (and multivalent cations) is higher than to monovalent cations.

A suitable ion exchange medium was used to capture and subsequently recover the cations.

soil quality . chemical methods . determination of cationic exchange capacity and extractible cations.

to the corundum structure except that the cations are of two different types.

The conversion affection of the substituted groups, metal cations on o-amino-diphenyl ether diazonium salt were studied.

Structural characteristics and sorptive behaviors and mechanisms for heavy metal cations of bentonite are analysed.

Toxicity can be prevented by addition of other cations which act as cation antagonists.

Freeze-thaw process might influence soil's aggregate and micropores, thus influence cations' adsorption on the soils.

The influences of cations and anions on the selective permeation of imprinted membranes were investigated.

The amphiphilic adsorbent has high capacity of adsorbing both organic pollutants and heavy metal cations.

than sulphate in many oilfield brines, we shall consider them cations and anions.

Being poly-anionic in nature, EPS form complexes with metal cations resulting in metal immobilization.

Ionic liquids are a series of novel liquids solely composed of organic cations and organic or inorganic anions.

and imidazoline quaternary ammonium salts were synthesized and the content of cations was determined.

The effects of different divalent cations and cycloheximide on DNA cleavage in this system were assessed.

The haemolymph cation levels were held by controlled excretion of the cations.

The PZ sensor for cations exhibited good selectivity and detection limit in aqueous solution.

The rates of elimination of cations were lower during feeding stages than during non feeding stages.

C36CH2 cations have antiaromaticity with negative resonance energy, whereas C36CH2 anions have aromaticity with positive resonance energy.

However, few studies had investigated the effect of freeze-thaw process on the adsorption of cations by the soils.

Polypyridines belong to polydentate ligands, which can chelated with transition metal cations to form metal coordination complexes.

anions and cations have opposite electrostatic charges. their attraction to each other forms covalent bonds.

Amphiboles are related to the pyroxenes, forming double chains, again being held together by cations.

Heats of hydration of divalent transition metal cations .

Analytical methods for 25 cations. 5 anions, as well as total residue, total oxide, density and free acid are developed.

Atoms which have lost one or more electrons become positively charged ions , and are called cations.

Metal with low ionization energy that loses electrons readily to form cations.

Implant positioning is important in avoiding potential compli? cations if closed LCP techniques are used.

DNA methylation, amongst the known epigenetic modi? cations, appears to play a crucial role in leukaemogenesis.
