Wastewaters containing Cu(II) along with ligands are ubiquitous in various industrial sectors. Efficacy of treatment processes for copper removal, especially precipitation, is greatly debilitated by ligands. Chemical reduction being commonly employed for production of metal nanoparticles has also been used for removing copper. Addition of ammonia was reported to be essential for improving coppe...

Actinomycetes are an uncommon agent of human infections and its pathogenic factors are not known. The present study reports a rare case isolation of an actinomycete from a woman pleural fluid; the strain was identified by 16S rRNA gene sequence analysis. This strain was tested to produce an extracellular protease that hydrolysis gelatin, casein and hemoglobin on agar mediums. The purification o...

Aims: The aims of this study was designed to analyze the released ions from Ag-Pd-Cu-Au alloys after a new sliding solubility test in different solutions with or without mucin. Materials and methods: Eluate solutions, similar to Fusayama’s artificial saliva, Hanks buffer solution, and artificial saliva with or without mucin were prepared. Ag-Pd-Cu-Au casting alloys were selected by particularly...

This paper presents an experimental and theoretical investigation of the causes of corrosion of stack in a cement plant. In this paper, information related to metallic stack failures are given in the form of a case study in Neka Cement Plant, Mazandaran, Iran. Heavy corrosion attacks were observed on the samples of stack. The failure can be caused by one or more modes such as overheating, stres...

A self-magnetically insulated ion diode was used to produce a pulsed beam of metallic ions from explosion emission plasma. The ratio integral transferred charge for the Al, Ti and Mo amounted at least 63% total charge. had design features, which consisted in bladed cathode removable perforated anode overlay made VT-8 alloy. Analysis mass characteristics current density waveforms by time flight ...
