Nuclear refrigerators

The following PSA of a refrigerated ammonia storage facility is from Papazoglou (1990a, 1990b). An obje ve of the work was to test PSA as it had been applied to nuclear power...

Hydrofluoric acid is an important refrigerant and it is used as a bulking agent in foam industries. It is widely used in the aluminum production industry, nuclear fuel, steel, petroleum refining, and fluoride salt production. 

An interesting example of a DR for optical observations below 1K in strong magnetic fields is reported in ref. [35], A multistage nuclear demagnetization refrigerator is... 

Many elements and compounds do not present an electronic magnetic moment, but their nuclei possess nuclear magnetic moments. These moments can be used for a magnetic refrigeration as it is done with electronic moments. Also in this case the minimum temperature, now in the microkelvin range, is reached when the spontaneous magnetic... 

Since the product slowly darkens on exposure to air, it should be stored under nitrogen in a refrigerator. The compound solidifies on cooling m.p. 16.0-16.5°. Nuclear magnetic resonance spectrum (neat, tetramethylsilane internal standard) singlets at d 7.00 (aromatic protons), 3.93 (CH2), and 2.24 p.p.m. (NH). 

Carbon dioxide (CO ) is the 18th most frequently produced chemical in the United States. It has numerous uses, including in refrigeration, in the manufacture of carbonated drinks (e.g., soda pop), in fire extinguishers, in providing an inert atmosphere (unreactive environment), and as a moderator for some types of nuclear reactors.
