Effect of nitrogen methylation on cation and anion...Focuses on the impact of nitrogen on cation and anion coordination by hexa-and heptaazamacrocycles. Description of the systhesis of the two polyazamacrocycles; Experimental section; Results and discussion.Bencini...
Removal of one electron from •NO creates the nitrosonium cation (NO+) which has the ability to react with nucleophilic centers, producing nitroso compounds. Nitrosyl halides are liberated when •NO reacts with fluorine, chlorine, or bromine. The half-life, solubility, and biological reactivity...
‘screen’ the negative charge of the phosphate groups. Thus, in the presence of polyvalent cation salts, nucleic acids would behave as uncharged polymers. More importantly, polyvalent cations can induce condensation of (coiled) DNA, giving rise to a more compact globular conformation (Khan and ...
Identify the cation and anion in the compound formed between aluminum and nitrogen. Write the name and formula of this compound. Name the following compound: CH_3-CH_2-CH_2-CH_2-CH_2-CH_2-CH_3. Give the name of the following compound: Correctly name the following compound. Name the ...
which has driven the development of many modifications of TiO2-based photocatalyst materials. Cation-doping or anion-doping of the oxide is presently regarded as a highly effective approach for enhancing the utilisation of visible light4,5,6,7, among which nitrogen-doping has received significant at...
Ammonia acts like a cation when it is protonated; therefore, it can be removed from air and liquids with a strong acid cation exchange resin or a weak acid cation exchange resin. When ammonia is present as the free base, a weak acid cation exchanger likeResin is preferred due to its high...
Among all these methods, Ion-exchange (IX) is considered to be a feasible process using anion exchange resin for its fast kinetics and high selectivity22, 23. IX methods have been suggested by Environmental Protection Agency (EPA) for the removal of nitrates from the groundwater and these ...
Akira TaishaUSUS4801713 * 1988年1月26日 1989年1月31日 Nippon Gohsei Kagaku Kogyo Kabushiki Kaisha Organic complexes of a cation of a heterocyclic nitrogen compound and an anion of a 2,5-disubstituted-7,7,8,8-tetracyanoquinodiethmane
(2014)designed a BES with multiple barriers to remove nitrate from groundwater without the intrusion of counter ions from the anolyte. The BES consisted of two tubes constructed similar to a tubular microbial desalination cell. The inner tube was made of cation exchange membrane as the anode ...
Furthermore, some DEGs in response to N deficiency, such as NATs, probable anion transporter 3, organic cation/carnitine transporter 4, and high affinity nitrate transporter 2.7, could be used to improve the tolerance of N deficiency in tea plants by genetic modification in future study....
