Possible Interaction: Copper and Nitrogen

“Superhyperfine splittings were observed in the g ⊥ region, indicating possible coordination of the copper to one or more nitrogen atoms.”

“RNA-Seq indicated distinct transcriptional responses: nitrogen affects transport of ions such as copper , whereas potassium targets the organization of other cellular components.”

“ Nitrogen addition enhanced the uptake of N, P, S, K, Mn, Cu and Zn by plants, while inhibited plant Fe uptake, but with no effect on the uptake of Ca or Mg.”

“… nitrogen (N) addition resulted in surface soil acidification and decreased acid buffering capacity, increased the availability …, phosphorus (P), sulfur (S) and DTPA-extractable iron (Fe), manganese (Mn), and copper ( Cu ) contents, depleted the sum of base cations calcium (Ca), magnesium (… sodium (Na), decreased the diversity of soil microbial community.”

“The coordination number between copper and nitrogen in copper-nitrogen based electrocatalysts is quite important for boosting the oxygen reduction reaction (ORR).”

“It has been found that two copper ions form complexes with the nitrogen atoms of the dendrimeric core by coordinate bonds.”

“ Nitrogen addition significantly decreased exchangeable Ca by up to 33% in large and small macroaggregates and exchangeable Mg by up to 27% in three aggregates but significantly increased extractable Fe, Mn and Cu concentrations (by up to 262%, 150%, and 55%, respectively) in all aggregate size classes.”

“Upon binding of a nitrogen ligand to copper , the hyperfine couplings of the in-plane nitrogen atoms of the porphyrin core are reduced by about 3 MHz.”

“The synthesis of chlorophyll and protein as well as carbohydrate and the uptake of phosphate and nitrogen were inhibited seriously by excess iron and copper.”

“At pD 9.5 the addition of copper deprotonated the nitrogen atoms of the imidazole ring and the backbone.”

“Increasing copper inputs (>10 mg l(-1)) progressively inhibited biological treatment of ammoniacal-nitrogen and carbon; this inhibition persisted into the recovery phase for nitrogen but not for carbon.”
