this study has been carried out to determine the accumulation of heavy metals (arsenic, copper, lead, tin and zinc) in fish samples collected from former tin mining catchment. total eight types of fish family having fifteen different species are identified. cyperinidae is the most abundant family with eight different species found in the catchment. fish samples were analysed by using inductivel...

The current work has been undertaken to see the effect of Gr/Sn as a solid lubricant for development hybrid aluminum metal matrix composite (HAMCs). HAMCs were fabricated by reinforcing 10 wt% (sillimanite + ilmenite) minerals with or without 1 Sn/Gr/both via stir casting technique. Optical microscopy revealed homogenous distribution reinforced particles refinement silicon. Vicker hardness show...
