Even the smallest particle of dust can affect the outcome of a delicate experiment.

Researchers observed how particles dispersed in the simulated atmosphere during the experiment.

Hot particles were found in the air near the nuclear power plant.

Be careful not to touch the hot particle.

The furniture factory discarded several damaged particle boards last week.

The alpha particles emitted from the radioactive source were detected by the instrument.

The particle accelerators at the research facility are helping scientists probe the fundamental structure of matter.

The research team observed how β-particles scattered when passing through the thin aluminum foil.

The research team tracked a Janus particle as it oriented itself at the oil–water interface, with one hydrophilic hemisphere in the water and the hydrophobic hemisphere in the oil.

The detector measured particle energies across a broad spectrum during the collision experiment.
