P. N. Lebedev's Ideas on the Nature of Molecular Forces

Identifying the unique ground motion signatures of supershear earthquakes: Theory and experiments

“…The strong adhesion forces generated between flat, polished surfaces are attributed to attractive van der Waals forces. These intermolecular forces can dominate if a small separation distance on the order of a wavelength (of visible light) or even less is sustained across a macroscopic distance (Deryagin, 1967). There appears to be very little published scientific literature (if any) on the dynamic shearing resistance of intermolecularly bonded surfaces.…”

Molecular dynamics study of nanobubbles in the equilibrium Lennard-Jones fluid

“…This model was employed in Ref. 24, where the probability to find a critical bubble whose volume and pressure inside can fluctuate is calculated.…”

“…In contrast to the NV Tensemble generally used for simulation of bubbles in a liquid, the pressure changes simultaneously with the change of the long-range coupling constant, and this change requires no time for equilibration. Indeed, the long-range part of interaction potential (24) stipulates an additional pressure in the bulk of a droplet…”

“…19 Modern theories (see, e.g., Refs. [20][21][22][23][24][25][26][27][28][29][30][31] are successful in interpretation of the vapor nucleation but less successful as applied to the bubble nucleation. A probable reason could be a worse convergence of the expansion for bubble work of formation in powers of the inverse bubble radius as compared to similar expansion for clusters.…”

“…The following theory extensions are worth mentioning. Deryagin, Prokhorov, and Tunitskii 24 and Alekseechkin 25 have investigated the equilibrium distribution of bubbles in two-dimensional phase space (the size of a bubble and pressure inside it or the density) and calculated the correction to Zeldovich factor due to pressure (density) fluctuations. Yamamoto and Ohnishi 26 treated bubble nucleation in a binary solution of noble gases.…”
