Natural gas hydrates (NGH) can only exist under low temperature (generally below 10 °C) and high pressure (generally above 3.8 MPa). The prerequisite for investigations of NGH sediments is a sampling technique that prevents its volatiles during recovery. In this paper, some pressure and...

The present study aims to investigate the comparative corrosion of light-weight metals such as aluminum and magnesium in palm biodiesel. Immersion test at room temperature was carried out for each metal for 1440 h. Sample characterization techniques employed include weight loss measurement, SEM...
