The Oligodynamic Effect: How Some Metals Kill Off …
It''s possible that Triclosan isn''t entirely healthy for us; worse, overuse may potentially be making some bacteria immune to Triclosan, and that''s a whole new mess. But overuse of Triclosan doesn''t mean we should stop caring about hygiene and let any old bacteria get us sick--we simply need to remeer that there are other solutions out there that can kill bacteria.

Basic ion exchange processes - Dardel
Removal of heavy metals from waste: Cd, Cr, Fe, Hg, Ni, Pb, Zn In many of these appliions, a residual concentration in the µg/L range is possible. Some contaminants are difficult to remove with ion exchange, due to a poor selectivity of the resins.
What Is Stainless Steel? - Analyzing Metals
“Stainless” steel is actually a generic term referring to a variety of steel types. Like all other kinds of steel, stainless steel is made primarily from iron and carbon in a two-step process. What makes stainless steel different is the addition of chromium (Cr) and other alloying elements such as nickel (Ni) to create a corrosion-resistant product.
