Platinum (disambiguation)
Platinum is a chemical element with symbol Pt and atomic number 78.
Cheapium
Cheapium is a term used for several theoretically stable binary platinum-group combinations sifted from thousands of potential platinum-group compounds using supercomputers, databases, and algorithms. By using theories on how atoms interact with model chemical structures to automate new compounds testing, years of laboratory research and money can be potentially saved to discover cheaper (thus the name Cheapium) alternatives to expensive currently known platinum based compounds. The term was coined by materials scientist Stefano Curtarolo as a mixture of inexpensive elements (cheap) having chemical, physical or structural property equivalent to an expensive and rare element (Expensium).
