Fluctuation approach to the problem of thermodynamics’ applicability to nanoparticles
The root-mean square fluctuations of the temperature and energetic surface tension of metallic and molecular nanoparticles have been estimated. It is revealed that the relative value of mentioned fluctuations is not higher than several percents even for the particles of 0.5 nm in size. We thus conclude that it is possible to apply the thermodynamic approach to nanoparticles with fluctuating properties, and the fluctuations do not lead to nanoparticle instability and decay.
