For Hollywood celebrities, the term “splitsville” usually means “check your prenup.” For scientists wanting to mass-produce high quality nanoribbons from boron nitride nanotubes, “splitsville” could mean “happily ever after.”

Splitting of a boron nitride nanotube to form a boron nitride nanoribbon shows atoms of boron in blue, nitrogen in yellow and potassium in pink. Pressure from potassium intercalation unzips the BNNT and forms layers of BNNRs.

Scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley, working with scientists at Rice University, have developed a technique in which boron nitride nanotubes are stuffed with atoms of potassium until the tubes split open along a longitudinal seam. This creates defect-free boron nitride nanoribbons of uniform lengths and thickness. Boron nitride nanoribbons are projected to display a variety of intriguing magnetic and electronic properties that hold enormous potential for future devices.
