Nanoparticles research is rapidly growing into an extensive research area. This is due to the fact that nanoparticles can be easily altered by varying their chemical environment, shape and size. One of the key benefits of nanoparticles is that their properties differ from bulk material of the same composition.
Tin is a malleable post-transition metal that is not easily oxidized in air. It can be coated onto other metals to prevent corrosion.
Tin nanoparticles have high surface activity, large specific surface area, good dispersion performance and uniform particle size. Tin nanoparticles dispersed in lubricating oil can be used as multi-purpose oil additives, which have the potential to reduce friction and wear in automobile engines.
