copper
The copper complexes of the above ligands were used in catalytic asymmetrical Henry reactions.
      
Comparison of antibacterial ability of copper and stainless steel
      
In this paper, the electro-analysis and spectrophotometric analysis methods were used to study the antibacterial ability of copper and stainless steel materials.
      
coli) and photo-bacteria were used as samples, the antibacterial effect of stainless steel was very weak, while the percentage of bacteria dying from exposure to metallic copper for 30 min was over 90%.
      
The antibacterial ability of copper has a potential application in the field of disinfection, food packaging and piping of drinking water.
      
According to the Ullman reaction mechanism, the synthesis of 1,5-di(o-anisidino)anthraquinone was achieved by the multiphase reaction of 1,5-dichloroanthraquinone in xylene and o-anisidine in the presence of copper metal powder and potassium acetate.
      
Nuclease activity of copper(II) complex containing 1,10-phenanthroline-5,6-dione and L-phenylalanine ligands
      
By submarine gel electrophoresis, we found that the copper(II) complex can cleave circular plasmid pBR322 DNA into nicked and linear forms in the presence of ascorbic acid and H2O2.
      
A novel epoxidized soybean oil (ESO) internally toughened phenolic resin(ESO-IT-PR) with both good toughness and excellent thermal stability was prepared as the matrix resin of copper clad laminate (CCL).
      
Correlative investigation of copper/low-density polyethylene nanocomposite on the endometrial angiogenesis in rats
      
Compared with those in the SO group, the significant increases in microvessel density (MVD) were observed on the 30th and the 180th day after the insertion of the bulk copper (P >amp;lt; 0.05).
      
The results show that Nano-Cu/LDPE have slighter influence on the endometrial angiogenesis than bulk copper.
      
Effect of hydrogen on stress corrosion cracking of copper
      
The effects of hydrogen on electrochemical behavior and susceptibility of stress corrosion cracking (SCC) of pure copper were studied.
      
SCC susceptibility of pure copper in a 1 M NaNO2 solution was increased by pre-charged hydrogen.
      
Progress in porphyry copper exploration from the Gangdise belt, Tibet, China
      
Stable isotope characteristics and origin of ore-forming fluids in copper-gold-polymetallic deposits within strike-slip pull-apa
      
Electrochemical reduction characteristics and the mechanism of chlorinated hydrocarbons at the copper electrode
      
The reduction mechanism and activity of the chlorinated hydrocarbons at the copper electrode were explored.
      
The experimental results showed that chlorinated alkanes and a portion of chlorinated aromatic hydrocarbons could be reduced directly at the copper electrode.
