Silicene: It Could Be the New Graphene

from Science News

The hottest celebrity in world of nanomaterials may soon face a new rival. Inspired by the Nobel Prize-winning creation of the carbon material known as graphene, physicists have now created atom-thin sheets of carbon's big brother, silicon.

Silicon shares many properties with carbon, which sits just above silicon on the periodic table. In 2007 Lok Lew Yan Voon and then-graduate student Gian Guzmán-Verri of Wright State University in Dayton, Ohio, proposed that silicon could exist in flat sheets similar to graphene, even though silicon doesn't naturally form the kind of atomic bonds needed to accomplish this.

They coined the new term for this material: silicene.

The automation of tasks at work and at home is just around the corner, including driving cars, piloting planes, delivering packages, and transporting weapons. Unmanned aerial vehicles are rapidly evolving to meet both society’s and the military’s needs in automation and better efficiency.
During her time as one of the first female fighter pilots in the US Navy, Dr. Missy Cummings observed that computers could take off and land a plane more precisely than humans. Because of this breakthrough and her fascination with this growing technology, she began human–drone interaction research.
