Surfaces of carbon steel (CS) exposed to mixed cultures of iron-oxidizing bacteria (FeOB) and dissimilatory iron-reducing bacteria (FeRB) in seawater media under aerobic conditions were rougher than surfaces of CS exposed to pure cultures of either type of microorganism. The roughened surface, demonstrated by profilometry, is an indication of loss of metal from the surface. In the presence of C...

Seawater is one of the most abundant and clean hydrogen atom resources on our planet, so production from seawater splitting has notable advantages. Direct electrolysis would not be in competition with growing demands for pure water. Using green electricity generated renewable sources (e.g., solar, tidal, wind energies), direct electrolytic into oxygen a potentially attractive technology under f...

The fatigue properties of a high-strength steel, structural and duplex stainless steel in artificial seawater were investigated. Consequently, test chamber for the existing ultrasonic stand was implemented. experiments performed with smooth specimens at loading R = −1 up to 2 · 109 cycles. fully submerged seawater. data statistically evaluated using pearl string method compared different SN cur...
