copper–zinc alloy undergoes partial oxidation into a wurtzite-like zinc oxide phase under reaction conditions. The CZA materials pretreated according to different activation protocols (Table1) and containing a significantly different amount of reduced zinc (49 and 16 mol%, respectively) show almost...
In developing the technique the reaction between copper and liquid, copper-saturated zinc in the temperature range 475–569°C was investigated. The reaction couple can be regarded as a semi-infinite diffusion couple and the growth rates for the intermetallic copper-zinc compounds ?, ?, and ?
Reaction of nano-ball allophone with zinc and copper and its mechanism by molecular orbital method Zinc and copper adsorption isotherm on two nano-ball allophane samples, namely one lower in Si/Al ratio (KyP: 1.34) and one higher Si/Al ratio (KnP: 1.98) ... A Ghoneim 被引量: 0发表:...

A full-length cDNA of 803 base pairs encoding a putative copper/zinc−superoxide dismutase (Cu/Zn-SOD) from Epinephelus malabaricus was cloned by the polymerase chain reaction approach. Nucleotide sequence analysis of this cDNA clone revealed that it comprises a complete open reading frame coding ...
Reaction with iron, copper or zinc oxides and sulfidesdoi:US4041128 AA process and apparatus are provided whereby sulfur and nitrogen oxides as well as carbon monoxides and unburned hydrocarbons are removed from internal combustion engine exhaust gases. The gases are passed through a chamber ...
SOD1 is a metalloenzyme that coordinates one copper and one zinc in the protein, and forms a dimer to exert full enzymatic activity to convert superoxide to oxygen and hydrogen peroxide, thus eliminating reactive oxygen species harmful to the cells. ...
