An investigation of collision dynamics of nanoparticles for a broad range of impact factors and collision speeds is presented. The investigation is based on molecular dynamics simulations in conjunction with the Lennard-Jones interaction potential thus making the results applicable for a broad range of material properties. Identification criteria are used to classify the collision dynamics into...

The reactive molecular collision is the fundamental microscopic event. that underlies the chemical reaction. The ability to describe this process from a knowledge of forces operating at the molecular level has long been the goal of the theoretical dynamicist. The field of reactive molecular collisions, and fields related to it, have been reviewed frequently within the last five years. For the n...

This paper speculates on the potential of a limited set of interacting particles to produce interesting temporal structures in a two dimensional world. Particles exchange information locally though global complex behavior emerges spontaneously. The imaginary physics of the world is described in an ensemble of 2D arrays. An autonomous genetic algorithm continuously aims to optimize the arrays in...

Interstellar clouds are mainly composed of hydrogen molecules whose molecular spectra are difficult to record. Major other components are polar molecules, whose rotational and ro-vibrational spectra are readily observed. Inelastic collisions of molecules with H2 and electrons are important processes to understand the formation and intensities of molecular spectral lines. We have calculated the ...

Collision detection between hard-sphere representations of molecules can be performed in interactive times on existing graphics hardware. This thesis presents a system that allows a user to interactively move a small drug molecule near a larger receptor molecule and have the system immediately inform the user when a collision between the two molecules has occurred. The system uses a 3-D grid da...

Penning ionization of iodomethane (CH3I) and diiodomethane (CH2I2) upon collision with metastable He(2S) atoms was studied by collision-energy/electron-energy resolved two-dimensional Penning ionization electron spectroscopy (2D-PIES) over a wide range of collision energies (20 – 350 meV). Collision energy dependence of partial ionization cross sections (CEDPICS) indicates that the interaction ...
