Low dimensional carbon and MXene based electrochemical
... electrodes are replaced by highly porous electrodes [15, 16]. The limitations of power sources such as batteries and fuel cells could be complemented by ECs because of their long cycle life and rapid charging and discharging rate at high power densities [6]. Consequently, ECs have attracted consider ...

Stellar Masses and the Main Sequence
... In general, the opacity of a star is proportional to its metal abundance (due to bound-free transitions and electrons supplied to H-.) The lower the metal abundance, the smaller the opacity, the less energy is trapped in the star doing work, the smaller the star, and therefore the hotter the star. 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.
