Molecular Cloud Evolution II. From cloud formation to the early
... It is also essential to model the evolution of the cloud within the frame of its more diffuse environment. Not only this is indispensible in order to model the cloud’s evolution as it exchanges mass and energy with its surroundings, but also to model the generation of turbulence in the cloud by the ...

Anomalous melting behavior of solid hydrogen at high pressures
... hydrogen would transform into a quantum liquid phase that would constitute a new state of matter, due to the fact that hydrogen has a very large zero-point energy at ultra-high pressures. Results from first-principles molecular dynamics (MD) simulations have indicated that liquid hydrogen undergoes ...

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.
