Engineering Mechanics of Soft Interfaces
We study two things:
1. How things break
2. How dry things become wet and how wet things become dry

EPFL's student solves a 100-year-old physics enigma
An EPFL Bachelor’s student has solved a mystery that has puzzled scientists for 100 years. He discovered why gas bubbles in narrow vertical tubes seem to remain stuck instead of rising upwards. According to his research and observations, an ultra-thin film of liquid forms around the bubble, preventing it from rising freely. And he found that, in fact, the bubbles are not stuck at all – they are just moving very, very slowly.
