Clamping instability and van der Waals forces in carbon nanotube mechanical resonators.

We investigate the role of weak clamping forces, typically assumed to be infinite, in carbon nanotube mechanical resonators. Due to these forces, we observe a hysteretic clamping and unclamping of the nanotube device that results in a discrete drop in the mechanical resonance frequency on the order of 5-20 MHz, when the temperature is cycled between 340 and 375 K. This instability in the resona...

van der Waals forces influencing adhesion of cells.

Adhesion molecules, often thought to be acting by a 'lock and key' mechanism, have been thought to control the adhesion of cells. While there is no doubt that a coating of adhesion molecules such as fibronectin on a surface affects cell adhesion, this paper aims to show that such surface contamination is only one factor in the equation. Starting from the baseline idea that van der Waals force i...

Resonant enhancement and dissipation in nonequilibrium van der Waals forces.

Dispersion forces between molecules that are in relative motion, coupled to baths at different temperatures, or in excited states, are calculated using a Green function Liouville space expansion that extends the celebrated McLachlan response theory to the nonlinear regime. Our dynamical theory is applicable to systems that may be in any initial nonequilibrium state and that are subject to an ar...

Interference pattern of the Coulomb and the strong Van der Waals forces in p - p scattering ∗

In order to confirm the strong Van der Waals force in the nucleon-nucleon interaction, it is proposed to measure precisely the angular distribution of the cross section of the low energy (Tlab = 20 ∼ 30MeV.) proton-proton scattering. By using the spectrum of the long range interaction obtained from the analysis of the phase shift data of the S-wave of the p-p scattering, a characteristic interf...
