Graphene was first observed, via electron microscope, in 1962 and studied only while supported on metal surfaces. The material was later rediscovered, isolated, and characterized in 2004.

The term “smorgasbord”, used to refer to a wide variety of things such as “the carnival was a smorgasbord of oddities and entertainment”, is derived from the Swedish word “smörgåsbord”, a traditional buffet style arrangement of a multitude of hot and cold foods typically laid out as a celebratory meal. The term became internationally known as a result of such meals served at the Swedish Pavilion’s “Three Crowns Restaurant” at the 1939 New York World’s Fair.
