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...

A model was developed to determine the influence of steel corrosion products on a-radiolytic corrosion of spent nuclear fuel inside a failed waste container. The model takes into account the a-radiolysis of water, the reaction of radiolytic H2O2 with UO2 both directly and via galvanic coupling with noble metal particles, the reaction with H2 via galvanic coupling, and the Fenton reaction. The d...

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 novel synthesis method for self-supported Pt nanoclusters (Pt NCs) comprised of interconnected 2-3 nm Pt nanoparticles was developed by employing the galvanic replacement process between Cu2O nanocubes and PtCl4(2-) ions. This discovered synthesis procedure eliminates the use of any polymer capping agents and enables a catalytically clean Pt surface. It is determined that the presence of H(+)...

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...
