An air ioniser (or negative ion generator or Chizhevsky's chandelier) is a device that uses high voltage to ionise (electrically charge) air molecules. Negative ions, or anions , are particles with one or more extra electrons , conferring a net negative charge to the particle.
For seasonal affective disorder (SAD), a randomized controlled trial (RCT) comparing high (4.5x10 14 ions/second) and low (1.7x10 11 ions/second) flow rate negative air ionization with bright light therapy found that the post-treatment improvement percentage was 57.1% for bright light, 47.9% for high-density ions and 22.7% for low-density ions.

This website is the first negative ions industry website in China, and its purpose is to rapidly promote the orderly development of the air negative ion (negative oxygen ion) industry. In 2020, the Tsinghua University successfully developed a medical-grade high-concentration negative oxygen ion generator.
Anion ion beam production was a major subject of study for tandem accelerator application, and one can find recipes and yields for most elements in the Negative Ion Cookbook. [7] Tandems can also be operated in terminal mode, where they function like a single-ended electrostatic accelerator, which is a more common and practical way to make ...
However, few negative hydrogen ions are created in a hydrogen plasma discharge. In order to generate a sufficiently high negative-ion density and obtain a decent negative-ion beam current, caesium vapors are added to the plasma discharge (surface-plasma negative-ion sources). [5]
Researchers from Mass General Brigham, a health care system in Boston, Massachusetts, shared with Fox News Digital some of the scientific developments and breakthroughs they expect to see in 2025.
