Do not think it is a stretch to adapt the famous Galileo's quote to atoms at the nanoscale! When we squeeze our view to the atomistic scale, atoms, small clusters, and nanoparticles are very dynamic. So much that we should treat nanomaterials as 4D objects. Indeed, their chemophysical properties depend on their shape, size, and chemical ordering. As a consequence, they rely on morphological changes too. In the case of metallic nanoparticles, typical time scales are as short as hundreds of ns. In this contribution, we will review human history alongside the development of new materials. We will also look at the future and the opportunities, needs, and current challenges the community working in nanomaterials face. Examples in nanocatalysis will be presented in more detail.
