slope of the South China Sea were broken using a metal probe and the isotopic numbers for these specimens were reported as an average of two analyses. Cleaned foraminiferans were then treated......
as starting materials. The materials were melted under argon gas in a mild steel crucible at 760 °C with a resistance furnace. The molten metal was poured into a preheated mild steel mould. The chemical... reports [3] which suggested that the growth of deposit can be developed at the film/metal interface due to high mobility of F ions. Hence, growth of deposit decreases with increasing film thickness......
