... In the universe the predominant form of energy is gravitational. Every mass spread out in space possesses gravita tional energy, which can be released or convelted into light and heat by letting the mass fall together. For any sufficient ly large mass this form of energy out weighs all others. T ...

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.
