Einfluss induzierter Turbulenzen auf die Synthese von Clathrat Hydraten in einem Rührreaktor bei unterschiedlichen Temperatur und Druckbedingungen
The ability of water to form cage-like structures and capture gas molecules under high pressure and low temperatures lead to problems in gas pipelines, especially in the mid-20th century. Also, there is an enormous amount of this so-called gas hydrate, captured in deep sea sediments or in terrestria...

The ability of water to form cage-like structures and capture gas molecules under high pressure and low temperatures lead to problems in gas pipelines, especially in the mid-20th century.
