copper sulfate was used as a precursor to prepare cuo nanoparticles in reverse micelles (o/w microemulsion).  this is a technique which allows the preparation of ultrafine metal oxide nanoparticles within the size ranging from 50 to 60 nm. the preparation of nano copper (ii) oxide studied was investigated in the inverse microemulsion system. therefore the nucleation of metal particles proceeds ...

Copper sulfate was given to male rabbits intraperitoneally and the copper concentrations in the plasma, red cells and EtOH-CHCl3 treated fraction of the cells were determined. The concentration of copper in the plasma increased markedly and in the red cells increased slightly after administration of 1 mg copper/kg of body weight, while the copper level in the EtOH-CHCl3 treated fraction remaine...

We have developed an electroformed copper lining having highly clean and smooth surface (i.e. little outgassing and high conductive copper) for use in accelerator components. The copper lining is produced by periodic current reversal electroforming with a low copper-content acid copper sulfate bath containing the specified amount of chloride ions (PR process). Deposit by PR process has the same...

Five copper (Cu) sources were studied at pH 2.5, 5.5, and 6.5 to determine how Cu affects phytate phosphorus (PP) hydrolysis by phytase at concentrations up to 500 mg/kg diet (60 min, 40-41 degrees C). Subsequently, Cu solubility with and without sodium phytate was measured. Adding Cu inhibited PP hydrolysis at pH 5.5 and pH 6.5 (P < 0.05). This inhibition was greater with higher concentrations...

The problem of de-industrialization has undergone a decisive transmutation in the past two decades, roughly from the moment when it was linked to proto-industrialization at the Budapest Economic History Conference in 1981.1 Also interacting with the remarkable efforts of Immanuel Wallerstein and his colleagues who dated the formation of a ‘‘world economic system’’ from the expansion of European...

The aim of present study was to determine the LC50/96 h value of copper sulfate and determine the growth performance of Caspian Sea kutum) Rutilus frisii kutum (fingerlings during 60-days sub-lethal copper (Cu). After acclimation period to two weeks, for determine the LC50/96 h value, total of 27 aquarium with a capacity of 60 L each stocked with 10 fishes an aquarium. Tunney four aquarium and ...

It has been postulated that inorganic polyphosphate (polyP) and transport of metal-phosphate complexes could participate in heavy metal tolerance in some bacteria. To study if such a system exists in archaea, the presence of polyP was determined by the electron energy loss spectroscopy (EELS) procedure and quantified by using specific enzymic methods in Sulfolobus acidocaldarius, Sulfolobus met...

BACKGROUND Industrial copper ingest is a common form of poisoning in animals. Zinc has an important role in the physiology of spermatozoa, in sperm production and viability. OBJECTIVE This study was set to investigate whether the adverse effects of long term copper consumption on quality of rat spermatozoa could be prevented by zinc therapy. MATERIALS AND METHODS Forty eight mature (6-8 wee...
