The impact of coarsening on nanomaterials can be both beneficial and detrimental. On one hand, it can lead to the formation of more stable structures, which is advantageous for certain applications. On the other hand, it can degrade the material's properties, such as its catalytic activity or mechanical strength. For example, in catalysts composed of nanoparticles, coarsening can reduce the surface area available for reactions, leading to decreased efficiency.
