Transormerless inverters are attractive solution for the grid connected photovoltaic (PV) systems. Unfortunately, it has issues on galvanic isolation between PV systems to the grid. When the galvanic isolation disappears from the PV inverter, leakage currents will flow in a resonant circuit formed by the ground capacitance, the converter, the ac filter and the grid. In order to avoid the leakag...

Stainless steel clad rebar (SCR) was investigated because it may become a cost-effective means of controlling corrosion in concrete under very aggressive environments. Sound SCR (316L cladding) resisted corrosion in saturated Ca(OH)2 solution (SCS) with up to 5 wt% chloride. Cladding breaks on SCR induced significant corrosion of exposed underlying CS in SCS with only 1 wt% chloride. A computer...

Fluoride galvanic cells employing CaF2 as electrolyte have not been as extensively employed for thermodynamic characterization of alloys and compounds as the oxide electrolyte cells based on stabilized zirconia. However, CaF 2 galvanic cells have many advantages over oxide electrolyte cells. These advantages, as well as the factors affecting the proper functioning of the CaF2 cells, are discuss...

A silver-deposited nickel (Ag/Ni) wire electrode was prepared via a galvanic replacement reaction between Ag+ and Ni in aqueous solution. It then found that the Ag/Ni could be modified with Pt simply by treating it an solution of K2PtCl4. Although deposition Ag on limited amount, forming deposits less than 100 nm size, considerable increase electrocatalytic currents for oxidation alcohols obser...

Steel is the type of metal most often used in engineering. This study aimed to improve mechanical properties mild steel terms hardness, ductility, and other compare hardness carburized by galvanic treatment with non-galvanic carburizing steel. research was carried out varying heat process, namely without galvanic, where process uses activated carbon coconut shell charcoal a weight percentage 80...
