Emission of molecular fragments synthesized in hypervelocity nanoparticle impacts Academic Article uri icon


  • We report on experiments with Aun nanoparticles (100 n 400) at velocities of 10-60 km/s. They are implanted virtually intact via hydrodynamic penetration. The products of the extreme pressure transient are observed by mass analyzing the ionized ejecta. Targets of labeled molecules (13C-, 15N-glycine) reveal fragmentation-recombination processes, producing CN- and OCN- with high efficiency (45%). This value is over two orders of magnitude larger than that obtained with atomic and small cluster projectiles. The experiments could simulate collisions of nanosized dust particles in interstellar space. 2008 Elsevier B.V. All rights reserved.
