Synthesis and Characterization of Nano-Structure Copper Oxide From Two Different Copper (II) Metal-Organic Framework Precursors

Nano-structured copper oxides were successfully prepared through direct calcination of 1D ladderlike metal-organic framework [Cu2(btec)(2,2'-bipy)2]∞, (btec = 1,2,4,5-benzenetetracarboxylate and 2,2'-bipy = 2,2'-bipyridine) and porous coordination polymer [Cu(BDC)(bipy)](BDCH2), (BDC = 1,4-benzenedicarboxylate; bipy = 4,4'-bipyridine). The nano-structure of the as-synthesized samples are charac...

Copper Sulphate and Disinfection of Water

lime, which, added in even so small an amount as 0 000426 gramme to a hundred cubic centimetres of water, kills all the micro-organisms within two hours. The bacteria appear to be acted upon much more promptly than the other organic matter present. For the removal of the excess of the agent the addition of sulphite of sodium (0 000209 gm.) suffices, and an excess of this substance up to 50 per ...

Plasma copper clearance and biliary copper excretion are stimulated in copper-acclimated trout.

Nonacclimated and Cu-acclimated rainbow trout (Oncorhynchus mykiss) exhibited equally rapid clearance of a single bolus of injected (64)Cu (3,780 nmol/kg) from the plasma (32-40 min to half- concentration). Eight hours after Cu injection, approximately 80% of the injected Cu was found in the liver. However, when Cu labeled with (64)Cu was presented intravascularly via continuous infusion at a r...

Copper and manganese induce yeast apoptosis via different pathways.

Metal ions are essential as well as toxic to the cell. The mechanism of metal-induced toxicity is not well established. Here, for the first time we studied two essential nutritional elements, copper and manganese, for their apoptotic effects in yeast Saccharomyces cerevisiae. Although beneficial at subtoxic levels, we demonstrated that at moderately toxic levels, both metals induce extensive ap...
