Graphene’s Humble Creation and Promising Future

by Kathy Chambers 05 Jan, 2015 in

Sometimes the ordinary things we use every day can lead to extraordinary discoveries.  This was truly the case when physicists Andre Geim and Konstantin Novoselov used the humble adhesive tape to extract single layers of graphene from graphite. 

Although graphene had been theorized years before, it was thought to be impossible to isolate such thin crystalline materials in a...

Amazing Aerogels

Aerogels are some of the most fascinating materials on the planet. They were discovered in the 1930s by Stanford University’s Samuel Kistler who proved that he could successfully replace a gel’s liquid with a gas by drying it, thereby creating a substance that was structurally a gel, but without liquid. Since their invention aerogels have primarily been made of silica but can be made of a growing variety of substances including transition metal oxides, organic polymers, biological polymers, semiconductor nanostructures,...
