We strive to identify generic physical processes that provide a unified point of view to nanoparticle growth and Ostwald ripening. To this end we have performed comprehensive laboratory experiments and numerical studies addressing droplet growth and the evolution of droplet size distributions in different fluids undergoing phase separation. We observe remarkable shortcomings of classical theories addressing the growth processes. The origins of the discrepancies are identified, and appropriate extensions of the theories are discussed.
