According to the level of measurement scale, friction force changes its nature and is determined by different depend-encies. The paper views a procedure for determining molecular component based on evaluation specif-ic shearing resistance links un-der elastic interaction silicon nitride cantilever needle having steel sample, used scanning section sample surface in nanometer range with an atomic...

The virial coefficients can be obtained from statistical mechanics in connection with the intermolecular potentials. The intermolecular potential of polyatomic molecules is usually assumed to consist of a spherically symmetric component plus a contribution due to asphericaity of the molecular charge distribution. In this study, the second virial coefficients have been calculated for N2...
