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.
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.
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.

It consisted of a tandem Van de Graaff generator operating routinely at 20 MV, housed in a distinctive building 70 m high. During its lifetime, it accelerated 80 different ion beams for experimental use, ranging from protons to uranium. A particular feature was the ability to accelerate rare isotopic and radioactive beams.
In a negative corona, the ions are attracted inward and the electrons are repelled outwards. The glow of the corona is caused by electrons recombining with positive ions to form neutral atoms. When the electron falls back to its original energy level, it releases a photon of light.
Negative ion products are products which claim to release negative ions and create positive health effects, although these claims are unsupported. [1] Many also claim to protect users from 5G radiation. These claims are likewise unsubstantiated. A market has developed for these products due to conspiracy theories about 5G. [2]
JEPQ data by YCharts.. Long-term dividend yields. The monthly payouts added up to $5.38 per share over the last year, or a 10.7% yield against the current share price of approximately $58.
The electrostatic repulsion of ions, ionic recombination, and air convection currents due to heating tend to break up ionized regions, so streamers have a short lifetime. In electromagnetism , a streamer discharge , also known as filamentary discharge , is a type of transient electric discharge which forms at the surface of a conductive ...
