Lecture 4: Molecular Clouds (1)
... The original gas is presumably atomic. Molecular clouds then form inside the condensing medium through their self-shielding from UV radiation. The observed drop in the H2 surface density between the arms implies that a typical GMC cannot survive as long as the interarm travel time of the Galactic ga ...

Microplasma
Microplasmas are plasmas of small dimensions, ranging from tens to thousands of micrometers. They can be generated at a variety of temperatures and pressures, existing as either thermal or non-thermal plasmas. Non-thermal microplasmas that can maintain their state at standard temperatures and pressures are readily available and accessible to scientists as they can be easily sustained and manipulated under standard conditions. Therefore, they can be employed for commercial, industrial, and medical applications, giving rise to the evolving field of microplasmas.
