Flüssigstickstoffbasierte

Flüssigstickstoffbasierte refers to technologies, processes, or applications that utilize liquid nitrogen as a key component. Liquid nitrogen is the liquefied form of nitrogen, a gas that makes up about 78% of Earth's atmosphere. It is produced by cooling nitrogen gas to extremely low temperatures, typically around -196 degrees Celsius (-320.8 degrees Fahrenheit). At this temperature, nitrogen transitions from a gaseous state to a liquid.

The extremely low temperature of liquid nitrogen makes it useful for a variety of applications. In cryogenics, it is used for preserving biological samples, such as cells, tissues, and semen, at very low temperatures to prevent degradation. It also plays a role in medical treatments like cryosurgery, where abnormal or diseased tissue is destroyed by freezing. In the food industry, liquid nitrogen is employed for rapid freezing of food products, which helps to preserve texture and flavor. This method is often referred to as cryogenic freezing.

Furthermore, liquid nitrogen-based systems can be found in scientific research, particularly in areas requiring low temperatures, such as in particle accelerators and for cooling superconducting magnets. In some industrial processes, liquid nitrogen is used for shrink-fitting metal parts, where it cools and contracts one part, allowing it to be fitted into another, and then expands as it warms, creating a tight fit. The rapid cooling property is also leveraged in some specialized cleaning or deburring processes. Its inert nature, combined with its low temperature, makes it a versatile cryogenic fluid.
