A transparent substance will allow light to travel through on a straight line, in a turbid substance the light will be scattered numerous times, traveling on more complicated zig-zag trajectories. But ...

Diffusive random walks feature the surprising property that the average length of all possible random trajectories that enter and exit a finite domain is determined solely by the domain boundary.

Photocatalysis for small-molecule activation has advanced considerably over the past decade, yet its scale-up remains challenging in part due to photon attenuation effects. One promising solution lies ...
