Highly curved carbon nanostructures produced by ball milling

The formation of nanoarches or highly curled carbon nanostructures during high energy ball milling of graphite is reported High resolution transmission electron microscopy indicates that graphite sheets with a thickness of less than 10 nm dimension along the c axis hold high flexibility and are highly bendable thus forming nanoarches or highly curved nanostructures upon ball milling.
