The intermolecular interaction energy components for several molecular complexes were calculated using force fields available in the AMBER suite of programs and compared with Density Functional Theory-Symmetry Adapted Perturbation Theory (DFT-SAPT) values. The extent to which such comparison is meaningful is discussed. The comparability is shown to depend strongly on the intermolecular distance...

The adhesion between a micro-object and a microgripper end-effector is an important problem in micromanipulation. Canceling or reducing this force is a great challenge. This force is directly linked to the surface chemical structure of the object and the gripper. We propose to reduce the adhesion force by using a self-assembled monolayer structuring on one surface. The surface was structured by...

This article delves into the ecofeminist themes present in Jeff Vander Meer’s novel "Annihilation," examining interconnectedness of humans and nature, portrayal female characters, idea feminine as a force transformation, critique humanity's relationship with nature. "Annihilation" challenges traditional notions femininity, agency through its depiction mysterious uncanny landscape Area X. The pr...

Drying simulations of nanoparticle suspension films on a substrate are carried out by a threedimensional simulator developed. The motion of nanoparticles in the suspension films is modeled by Langevin equation, in which forces exerted on each nanoparticle consist of contact force, capillary force, Brownian force, van der Waals force, electrostatic force and fluid drag force. The drying of suspe...

We consider the effect of the image interaction on the force acting between tip and surface in non-contact scanning force microscope experiments. This interaction is relevant when a conducting tip interacts with either a polar bulk sample or with a thick film grown on a conducting substrate. We compare the atomistic contribution due to the interaction between the microscopic tip apex and the sa...

In this paper, a micro electromagnetic harmonic drive system is proposed. Considering Van der Waals force, dynamics equation of the flexible ring for deduced and resolved. Using equations, effects molecule force on natural frequencies vibration modes are investigated. Results show that considering reduced its changed. For lower order modes, smaller clearance between stator, thickness larger rad...
