Femtosecond time-resolved single-particle spectroscopy directly visualized exciton diffusion within individual copper phthalocyanine（CuPc）nanofibers. The exciton diffusion coefficient（D）differs ...

A few years ago, a new kind of AI called a diffusion model appeared. Today, it powers tools like Stable Diffusion and Runway Gen-2, turning text prompts into high-quality images and even short videos.

Diffusion models gradually refine and produce a requested output, sometimes starting from random noise—values generated by the model itself—and sometimes working from user-provided data. Think of ...
