If you're drinking a cup of coffee for #InternationalCoffeeDay, or any other beverage, you may notice the coffee-ring effect (CRE).

When a turbid drop dries on a solid surface, its suspended particulates will be deposited in a ring-like pattern.

Researchers leveraged CRE to obtain the patterned deposition of nanoparticles on a titanium substrate, which could improve  NP-printed circuit boards and site-specific delivery of drugs.
