Why is Coulomb Interaction Important in Nanotechnology?
At the nanoscale, particles are often charged or exhibit significant charge distributions, making Coulomb interactions a key factor in determining their properties and behaviors. For instance:
Stabilization of Nanoparticles: Electrostatic repulsion between similarly charged nanoparticles can prevent aggregation, thus stabilizing colloidal dispersions. Self-Assembly: Coulomb interactions can drive the self-assembly of nanostructures, enabling the formation of ordered arrays and functional materials. Surface Functionalization: The adsorption of charged molecules on nanoparticle surfaces can be controlled by tuning the Coulomb interactions, allowing for tailored surface properties.
