One proposed mechanism for forming COMs in these sources is that simple ices formed on grain surfaces at 10 K (e.g., CO, H2 O, NH3 , CH4 , and CH3 OH) undergo warming to ≈ 20 – 30 K (caused by the ignition of the embedded star) where the grain-surface molecule ...

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.
