Low temperature engineering applications of neon
It is well known that the liquid temperature range of the industrial gas helium is 2×10-3-5.20 K, the liquid temperature range of hydrogen is 14.2-33.0 K, and the liquid temperature range of the industrial gas neon is 24.5-44.40 K. Because neon is chemically inert and has a high latent heat of evaporation (2.7 times that of liquid hydroge...

Advantages of carbon dioxide mixture in welding process
Pure carbon dioxide is a heavier gas than air and has high thermal conductivity, resulting in a wider arc and weld. However, it also has strong oxidizing properties, which leads to larger spatter during welding. On the other hand, argon is also heavier than air and can effectively protect the molten droplets and weld pool during welding, r...

Principle of operation of argon fluoride excimer lasers
The Argon Fluoride Excimer Laser is a laser device that utilises the excited state decay of the excimer ArF* to emit 193nm photons. The principle of operation is quite subtle, with the amplification and emission of photons being achieved by a discharge and reaction process. As the discharge passes through the Ar/F2 mixture, Ar+ ions ...
