Passivation behavior of high silver containing copper anodes was investigated using slowly cooled Cu- 1%Ag different lead (Pb) concentrations. The addition Pb distributes in the phase and reduces amount that is solidly soluble and, thus, generates a fine powder on anode surface which main contributing factor passivation. Electrorefining experiments were conducted synthetic electrolyte 40 g/L Cu...

anode slimes are a by-product of the electrolytic copper refining process, which contain the precious and other important metals .in order to find a suitable method for treating these materials it is necessary to know their phase composition. for the separation of various phases from the complexmixture of copper anode. slime, the slime is leached in various steps and the residues of each step a...

Here we report a chemical-free, simple, and novel method in which a part from a silver-based anode is controllably used in a straightforward manner to produce silver nanoparticles (Ag NPs) in order to fabricate a controlled assembly of Ag NPs and single walled carbon nanotube (SWCNT) hybrid structures. The attachment and distribution of Ag NPs along SWCNTs have been investigated and characteriz...

In the present study, semi-purified laccase from Trametes versicolor was applied for the synthesis of silver nanoparticles, and the properties of the produced nanoparticles were characterized. All of the analyses of the spectra indicated silver nanoparticle formation. A complete characterization of the silver nanoparticles showed that a complex of silver nanoparticles and silver ions was produc...

This paper introduces Die Lebensfreude, a pioneering piece of music composed with the aid of an amoeba-like plasmodial slime mould called Physarum polycephalum. The composition is for an ensemble of five instruments (flute, clarinet, violin, cello and piano) and six channels of electronically synthesises sounds. The instrumental part and the synthesised sounds are musifications and sonification...

Plasmon-assisted energy conversion is investigated in a comparative study of dye-sensitized solar cells (DSCs) equipped with photo-anodes, which are fabricated by forming gold (Au) and silver (Ag) nanoparticles (NPs) on an fluorine-doped tin oxide (FTO) glass surface by means of dry plasma reduction (DPR) and coating TiO₂ paste onto the modified FTO glass through a screen printing method. As a ...

The present work is dedicated to further development of the laser synthesis method for metal nanoparticles formation at air conditions. On the base of complex investigation of processes taking place during laser erosion of metals by intensive nanosecond pulses the method of silver nanoparticles fluxes is proposed. By the implantation of silver nanoparticles into liquid media (water or solutions...
