Entropy is a measure of the disorder or randomness in a system. At the nanoscale, the entropy of a system can be significantly influenced by factors such as particle size, shape, and surface chemistry. For instance, smaller nanoparticles tend to have higher entropy due to their increased surface-to-volume ratio, which contributes to greater atomic mobility and positional disorder. This can impact the thermodynamic stability and self-assembly of nanostructures.
