Explore the fundamental concept of matter in physics, everything that makes up the physical world around us. Matter is not ...

This paper presents the evolution of striated discharge patterns in helium and argon atmospheric-pressure plasma jets as a function of gas flow rate and driving voltage. The striated patterns have ...

Various geophysical models have shown that Ar, a natural decay product of 40K, is depleted in Earth’s main reservoirs (i.e., continental crust, atmosphere, and silicate mantle). This indicates that a ...

Nonthermal plasma jet was generated by dielectric barrier discharge (DBD) with a 34-kHz sinusoidal power supply in argon. The power consumption ranged from several to tens of watts. The flow rate of ...

Coal seam gas pressure is one of the basic parameters for coalbed methane resource exploitation and coal mine gas disaster prevention. However, the present coal seam gas pressure measurement ...
