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.

Positron emission particle tracking (PEPT) is a powerful, non‐invasive technique that utilises radioactively labelled tracer particles to visualise and quantify the complex internal dynamics of ...

MPT is a recently developed technology that can measure the translation and rotation motion of a particle in an opaque environment. This technique has potential applications in studying the accurate ...

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.
