Muons are a key subatomic particle in the discovery of new physics, but after particle collision, they’re difficult to track.

Tunable red to green emissions in upconversion nanoparticles allow precise identification of single particles, enabling accurate, long-term multicolor tracking in complex live cell environments.

Large amounts of dust are released from traffic emissions, industrial operations, and waste disposal activities, directly or indirectly pollute the environment, especially the soil and the atmosphere.
