Nitrogen generators are closely related to our lives
Jul 17, 2017

The application of medicine:

The use of liquid nitrogen to the scalpel cooling, it becomes a "cold knife." Doctors with "cold knife" surgery, can reduce bleeding or no bleeding, patients can recover faster after surgery. The use of liquid nitrogen for the treatment of skin diseases, the effect is also very good. This is because the liquid nitrogen gasification temperature is -195.8 ℃, therefore, used to treat superficial skin disease is often very easy to make the lesion at the skin necrosis, shedding. In the past dermatology often "dry ice" treatment of hemangioma, although the same intention, but the cold far less than liquid nitrogen. Treatment of tuberculosis "artificial pneumothorax", but also the nitrogen (or air) into the thoracic cavity of patients with tuberculosis, compressed lesions of the lungs, so that it is rest.

temperature control:

Now, people also use liquid nitrogen to produce low temperature, to save the sperm of the improved livestock, storage and transportation, thawed and then used for artificial insemination. Such as the Guangxi Provincial Fisheries Research Institute of liquid nitrogen storage salamander fish semen, was successful. Nitrogen or an important chemical raw materials, can be used to produce a variety of fertilizers, explosives and so on.

Scientific development:

Scientists have great hope for nitrogen, they think; Rhizobium has a set of wonderful trick, can be directly in the air to capture nitrogen into nitrogen. Because it has a nitrogenase in the body, this enzyme is to capture the nitrogen experts, if we can use chemical methods to manually synthesize a large number of ammonia bacteria, would not easily change nitrogen nitrogen fertilizer it?
