A new computer program simulates Brownian motion and diffusion for 40-100 molecules. This tool visualizes molecular trajectories and concentration changes, aiding in understanding diffusion and membrane permeability.

Area of Science:

  • Computational physics
  • Physical chemistry

Background:

  • Diffusion is a fundamental physical process crucial for understanding molecular transport.
  • Simulating molecular behavior aids in visualizing complex phenomena like Brownian motion.

Purpose of the Study:

  • To develop a computational tool for simulating diffusion processes.
  • To visualize single-molecule trajectories under Brownian motion.
  • To plot concentration-time and concentration-distance functions.

Main Methods:

  • Development of a computer program for molecular simulation.
  • Simulation of 40 to 100 molecules in a confined space.
  • Inclusion of barriers within the simulation environment.
  • Graphical plotting of concentration-dependent variables.

Main Results:

  • The program successfully displays individual molecular trajectories during Brownian motion.
  • Simulations can be performed with varying numbers of molecules (40-100).
  • The software generates plots for concentration-time and concentration-distance relationships.

Conclusions:

  • The developed program offers a visual aid for understanding diffusion.
  • It can be a valuable educational tool for teaching diffusion and membrane permeability.
  • Complements experimental and theoretical approaches to studying diffusion.
