The seeds must have the same chemical composition and crystalline structure as that of the larger crystal. The practice is used in semi-conductor industries and making artificial single

The major difference between Compressed Natural Gas (CNG) and Liquefied natural gas (LNG) is that the former is NOT liquefied. CNG involved compressing the natural gas to less than 1% of the volume it occupies at standard atmospheric pressure. It is stored and distributed in hard containers at a pressure of 200–248 bar (2900–3600 psi),
