The properties related to mechanical wave propagation in carbon nanotubes support advanced applications as nanomechanical resonators. This study deals with molecular dynamics simulations of cantilevered carbon nanotubes considered as mass detectors. The shift of the resonance frequency is calculated versus the attached extra-mass to carbon nanotubes model of 2200 atoms. We found that the modified Morse potential leads to the mass detection limit of 7.5 × 10-22 g and to a high efficiency computation needed for large atomistic models. The influence on the frequency shift determined by the position of the extra-mass along the single-walled carbon nanotubes was taken into account..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
