In this study, we demonstrate a rapid treatment method for producing a needle-like nanowire structure on a hot-dip galvanized sheet at a temperature of 50 °C. The processing method involved only supercritical carbon dioxide and water to induce a reaction on the zinc surface, which resulted in growth of zinc hydroxycarbonate nanowires into flower-like shapes. This artificial patina nanostructure...

the study examined the utilization of information and communication technologies by agricultural extension workers in niger state, nigeria. to achieve the study objective, 206 respondents were proportionately and randomly selected from the three agricultural zones in the state through multi-stage sampling technique. validated questionnaire with reliability coefficient of 0.81 was used to collec...

This paper investigates the physical reasons for apparently poor conductivity of galvanized steel plates (GSP), which has not yet received a proper explanation. Apparent conductivities as low 0.1 MS/m were reported in past, are incongruously compared to DC steels (4 8 MS/m), or zinc (16.7 most common coating agent used against corrosion products. A comprehensive review results from metallurgy a...

The galvanized steel sheet has been used widely in various fields. However, zinc, which a low melting temperature, evaporates and penetrates into the joint during conventional welding process, thus temperature process is required. Linear Friction Welding (LFW) solid-state joining uses friction heat generated at interface when materials are butted together. Recent studies reported that lower hig...
