Two Russian scientists have been awarded the Nobel Prize for discovery of a one-atom thick material called graphene that has significant potential for electronic applications, including semiconductors. In what appeared to be just a wacky experiment at the time, they applied Scotch tape to a sheet of graphite and extracted the extremely thin, totally transparent material with excellent strength and electrical properties.
Andre Geim and Konstantin Novoselov will split the prize of about $1.4 million.
Hundreds of researchers are now exploring potential for the material as ultracapacitors, sensors, touchscreens, liquid crystal displays, organic photovoltaic cells, and organic light-emitting diodes.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Using simulation to guide the drafting process can speed up the design and production of 3D-printed nanostructures, reduce errors, and even make it possible to scale up the structures. Oak Ridge National Laboratory has developed a model that does this.
