suspended within dynamic liquid thin films in a microfluidic vortex fluidic device (VFD). The method
produces sliced CNTs with minimal defects in the absence of any chemical stabilizers, having broad
length distributions centred at ca 190, 160 nm and 171 nm for single, double and multi walled CNTs
respectively, as established using atomic force microscopy and supported by small angle neutron
scattering solution data. Molecular dynamics simulations on a bent single walled carbon nanotube
(SWCNT) with a radius of curvature of order 10 nm results in tearing across the tube upon heating,
highlighting the role of shear forces which bend the tube forming strained bonds which are ruptured by
the laser irradiation. CNT slicing occurs with the VFD operating in both the confined mode for a finite
volume of liquid and continuous flow for scalability purposes
