  "term": "Diffusion battery",
  "field": "Chemistry",
  "definition": "An instrument used to measure the size distribution of submicrometer aerosol particles. It consists of a series of screens or channels through which the aerosol passes, allowing particles to deposit by diffusion based on their size. The fraction of particles penetrating each stage is measured to determine the particle size spectrum, with smaller particles depositing more readily.",
