How nanoparticles reduce surface energy
Combine individual nanostructures together
To form large structures
Reduce surface area
Mechanism >
Sintering
Individual structure merge together
Ostwald ripening
Smaller structures expense to grow large structures
Agglomeration of individual nanostructure
Without altering
Mechanisms
Surface atoms/ions shift inwardly
Surface restructuring
Combining surface dangling bonds into strained new chemical bond
Surface absorption through chemical/physical absorption of terminal chemical species onto surface
By forming chemical bond/ weak attraction force
Composition segregation / impurity enrichment
On surface through solid-state diffusion
