2. Air ioniser - Wikipedia

   en.wikipedia.org/wiki/Air_ioniser

   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.

3. Electrostatic generator - Wikipedia

   en.wikipedia.org/wiki/Electrostatic_generator

   An electrostatic generator, or electrostatic machine, is an electrical generator that produces static electricity, or electricity at high voltage and low continuous current. The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained merely an interesting and mystifying phenomenon , without a ...

   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.

6. Van de Graaff generator - Wikipedia

   en.wikipedia.org/wiki/Van_de_Graaff_generator

   Van de Graaff generators are still used as accelerators to generate energetic particle and X-ray beams for nuclear research and nuclear medicine. [2] The voltage produced by an open-air Van de Graaff machine is limited by arcing and corona discharge to about 5 MV. Most modern industrial machines are enclosed in a pressurized tank of insulating ...
