Man, I love nerdy stuff like this.
Researchers have determined how to get sheets of black phosphorus - a material similar to graphene (the 'next' silicon).
Rather than tediously peeling away layers, they found that by submerging the black phosphorus material in a liquid solvent and then bombing it with sound waves, the same effect could be achieved a whole lot easier and a whole lot cheaper. So: the sheets just kind of shake apart, yielding sized-to-order sheets of black phosphorus just a few atoms thick.
science is rad.
