According to the writers of buy dissertation online, in Physics, the study in which we observe the behaviour and production of different materials at very low temperature is known as cryogenics. A person who studies these materials at a very low temperature is known as cryogenicist. The temperature for material to cryogenics and refrigerate a material is not defined. According to scientists, if we want to refrigerate a material, we have to cool it up to -150-degree centigrade. The first cryogenic processing industry was found in 1966. Nowadays, this technique is used for the freezing and chilling processes. The cryogenics may play the following roles in the future;
Nuclear magnetic resonance
Nuclear magnetic resonance or NMR is an essential method to determine the chemical and physical properties of the atoms. These physical and chemical properties of the atoms are determined on the basis of the absorption of the radio frequency. The NMR technique is playing a role in various fields of industry. One of the most important examples of this phenomenon is that we can create a strong magnetic field of the magnets with the help of supercooling electromagnets. There are also some cheap metallic superconductors that are used for the coil wiring. In the future, it is also expected that high-temperature superconductors may play their roles in the field cryogenics.
Magnetic resonance imaging
The MRI or magnetic resonance imaging is a complex application of NMR. With the help of MRI, it is possible for us to deconvolute the geometry of different resonances. After that, it is used to detect the relaxation of protons in order to perturb the relaxation of the protons in the strong magnetic field. Mostly, MRI is used in different health applications.
In large cities
In the small cities, it is possible for us to transmit power with the help of the overhead cables. On the other hand, in the case of the big cities, it is difficult for us to transmit power with the help of overhead cables. For this reason, underground cables are used. Now, the problem with the underground cables is that these are heated and their resistance increases. As a result, these wires may lose some portion of the power. In order to solve this problem, we are using superconductors. Along with these superconductors, some cryogenic liquids are also used. These cryogenic liquids cool down the temperature and power is transmitted without any loss.
Nowadays, cryogenic gases are not only used in the storage of the large masses of frozen foods but these gasses are also used in transportation. That’s why it is possible for us to transport a large quantity of food from one place to another without any harm. We are also able to preserve the food at the places of the war and earthquake with the help of these essential techniques. The large scale food industries are also using this technique to preserve the food.
There are also some experiments which require cryogenic temperature for their performance. Therefore, we can also say that this technique is also useful for the research process.
