Microheterogeneous singlet oxygen generation at air–water interfaces

Singlet oxygen (1 O 2) drives key photochemical reactions in the atmosphere and natural waters, yet its spatial distribution in multiphase systems remains unexplored. Here, we reveal strong microscale ...

Proof of the Ergodic Theorem

Proof of the Ergodic Theorem Two such sets S λ * belonging to different λ ’s are evidently distinct except for a set of measure 0. Hence there can exist only a numerable set S λ i * (i = 1, 2,) of ...
