The authors' main claim The barriers of relative rotation of shells are found to be surprisingly small; therefore, free relative rotation of shells can take place at room temperature.

The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence

arXiv listing abstract v2. Results and the main claim are underlined; .

The energetic characteristics of two-shell carbon nanoparticles ("onions") with different shapes of second shell are calculated. The barriers of relative rotation of shells are found to be surprisingly small; therefore, free relative rotation of shells can take place at room temperature. The intershell orientational melting of the nanoparticle $C_{60}@C_{240}$ is studied by molecular dynamics. The parameters of Arrhenius formula for jump rotational intershell diffusion are calculated. The definition of orientational melting temperature is proposed as the temperature when the transition probability over barrier between equivalent potential minima is equal to 1/2. The temperature of orientational melting of the nanoparticle $C_{60}@C_{240}$ is about 60 K.

The paper
Original abstract

The energetic characteristics of two-shell carbon nanoparticles ("onions") with different shapes of second shell are calculated. The barriers of relative rotation of shells are found to be surprisingly small; therefore, free relative rotation of shells can take place at room temperature. The intershell orientational melting of the nanoparticle $C_{60}@C_{240}$ is studied by molecular dynamics. The parameters of Arrhenius formula for jump rotational intershell diffusion are calculated. The definition of orientational melting temperature is proposed as the temperature when the transition probability over barrier between equivalent potential minima is equal to 1/2. The temperature of orientational melting of the nanoparticle $C_{60}@C_{240}$ is about 60 K.
