Nitrite reduction by copper complexes.
A series of copper complexes have been synthesised as potential agents for the catalytic reduction of nitrite anions. The ligands and corresponding copper complexes have been characterised by using a range of techniques including X-ray crystallography, NMR, microanalysis, mass spectrometry, infra-red spectroscopy, electrochemical studies and density functional theory calculations. For complexes...
متن کاملDIRECT REDUCTION OF SARCHESHME COPPER SULFIDE CONCENTRATE WITH CARBON IN THE PRESENCE OF LIME
Abstract: The direct reduction of copper sulfide concentrate from Iranian Sarcheshme deposits with carbon in the presence of lime was investigated in the temperature range of 800-1000 ºC. The reduction kinetics was determined by means of weight loss measurements. It was found that the rate of reaction increased considerably with increasing the temperature. The kinetics was also improved whe...
متن کاملKinetics of Nitric Oxide Production and MTT Reduction by HSV-1 Infected Macrophages
Background: Macrophages have important role in defense against Herpes Simplex Virus type-1 (HSV-1). The present study was performed to determine the viability and nitric oxide (NO) production by HSV-1 infected mouse peritoneal macrophages (HIM). Method: The viability of macrophages was evaluated using MTT reduction assay and the production of nitrite using Griess method. Results: The ability of...
متن کاملEndocytic and NBT-reduction activities and TNF expression by macrophages and monocytes of the armadillo (Dasypus novemcinctus)
The armadillo could be considered as an experimental model for leprosy studies. Mycobacterium leprae main host cells are macrophages and Schwann cells. However, endocytosis and germicidal activities of armadillo macrophages and monocytes have not yet been evaluated. The aim of this research was to evaluate endocytosis and NBT-reduction activities of monocyte-derived macrophages (MDM) and monocy...
متن کاملCopper Reduction and Contact Killing of Bacteria by Iron Surfaces.
The well-established killing of bacteria by copper surfaces, also called contact killing, is currently believed to be a combined effect of bacterial contact with the copper surface and the dissolution of copper, resulting in lethal bacterial damage. Iron can similarly be released in ionic form from iron surfaces and would thus be expected to also exhibit contact killing, although essentially no...
