In this work, the deposition of gold on copper substrates from solutions of HAuCl 2 O in 1butyl1methylpyrrolidinium dicyanamide was studied. Deposition was carried out in opencircuit and under potentiostatic control at temperatures from 293 to 353 K, in normal atmosphere, with deposition conditions allowing water from atmospheric absorption up to wt.%.

Ionization system (ionic mode) The bioenergy system interacts with the bio energy of your own body during the localization of gold and silver objects to observe minimum changes of object substances. Thereby the gold detector Bionic 01 is able to locate almost all metallic objects.

corrosion failures in the integrated circuits and electronic components can occur even at extremely low levels of moisture and contamination. The presence of ionic contamination on a surface of a printed circuit board assembly (PCBA) acts as an accelerating factor for corrosion. Most ionic residues are hygroscopic and assist the
