Medical-grade negative oxygen ion generator: How does Tsinghua University in Tianjin promote the future of air purification technology?
Amid the increasingly severe air pollution problem, negative oxygen ions (NAI) have gradually become an important air component for improving human health and the environment. Negative oxygen ions refer to negatively charged molecules or ion aggregates in the air and are a common phenomenon in nature. With the advancement of science and technology, this concept has also been continuously improved, especially Tsinghua University's innovative application of negative oxygen ion technology, which has brought this technology into a new era.
Negative oxygen ions play an indispensable role in maintaining climate balance and improving human health.
Discovery and research history of negative oxygen ions
The research history of negative oxygen ions can be traced back to the 19th century, when German scientists first discovered the existence of negative oxygen ions in 1889. Subsequently, many scholars, including physicist Leonard, conducted in-depth discussions on its biological significance and pointed out the impact of negative oxygen ions on humans, animals and plants. Over the past few decades, with the continuous advancement of medical technology, the application of negative oxygen ions has gradually expanded to clinical practice, becoming a new way to treat various diseases.
Tsinghua University's innovative breakthroughs
In 2020, Tsinghua University successfully developed a medical-grade high-concentration negative oxygen ion generator. The innovation of this device is that it can form a uniform and dense layer of nanoparticles simply by spraying it on the walls of the room, releasing high concentrations of negative oxygen ions in a long-lasting and stable manner, thereby improving indoor air quality.
This technology represents a significant advancement in air purification technology and has the potential to change our living environment in the future.
Generation mechanism of negative oxygen ions
Negative oxygen ions are mainly generated by two methods: natural and artificial. In the natural environment, phenomena such as waterfalls and lightning can naturally produce a large amount of negative oxygen ions. Artificial methods, such as coronal discharge and water vapor, are a more controllable way to generate it. Both have their advantages and disadvantages, and naturally generated negative oxygen ions usually have a more significant impact on environmental health.
Health Benefits of Negative Oxygen Ions
Scientific research shows that negative oxygen ions can promote human health, including improving cardiovascular and respiratory system functions, and alleviating depression symptoms. Relevant experiments have shown that after inhaling negative oxygen ions, participants’ performance in various tests was significantly improved, especially in alleviating seasonal affective disorder, which is comparable to antidepressant drugs.
Potential for environmental improvement
In addition to physiological health, negative oxygen ions also play an important role in removing indoor air pollutants. Experiments show that through the study of negative oxygen ions, the concentration of suspended particulate matter can be effectively reduced, thereby improving the indoor living environment.
Using negative oxygen ion technology is expected to simplify our air quality improvement program.
Future Outlook
In the future, negative oxygen ion technology is expected to be used in a wider range of fields, not only limited to medical care, but may also involve air purification, environmental protection and other aspects. With the successful research and development of Tsinghua University, negative oxygen ion generators may lead a new air purification technology revolution and benefit more people.
When considering the potential environmental and health benefits of negative oxygen ions, we can't help but ask: Can future urban life be fresher and healthier because of this technology?
