Rb adsorbate-induced negative electron affinity on quartz
... In this work, we show that adsorption of Rb atoms on a quartz (0001) surface, contrary to prevailing assumption, can reduce the E-field near the surface, using spin-polarized density functional theory (DFT). On the surface of quartz, the Rb atom is bound to two oxygen atoms. Total-energy calculation ...

Sources of energy and the origin of the chemical elements
... White Dwarfs When the triple-α process in a red-giant is complete, the star core starts contracting. For a main sequence mass of M < 4 M¤ there is not enough energy to ignite the carbon fusion process, thus the collapse keeps going until it is halted by the pressure arising from electron degenerac ...

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.
