Vibrational characterization of dinaphthylpolyynes: A model system for the study of end-capped sp carbon chains
Eugenio Cinquanta, Luca Ravagnan, Ivano Eligio Castelli +4
We perform a systematic investigation of the resonance and vibrational properties of naphthyl-terminated sp carbon chains (dinaphthylpolyynes) by combined multi-wavelength resonant…
Carbon sp chains in graphene nanoholes
Ivano E. Castelli, Nicola Ferri, Giovanni Onida +1
Nowadays sp carbon chains terminated by graphene or graphitic-like carbon are synthesized routinely in several nanotech labs. We propose an ab-initio study of such carbon-only mate…
Mechanical properties of carbynes investigated by ab initio total-energy calculations
Ivano E. Castelli, Paolo Salvestrini, Nicola Manini
As sp carbon chains (carbynes) are relatively rigid molecular objects, can we exploit them as construction elements in nanomechanics? To answer this question, we investigate their…
