In this paper, operational limitations (the extinguishing of the stable glow discharge) and instabilities [glow-to-arc transition (GAT)] of microwave-induced microplasmas enclosed in microcavities operated at low gas pressures were investigated by experiments, in comparison with unenclosed microplasmas. For enclosed microplasmas, when gas pressure decreased, GAT occasionally occurred, whereas GAT...
Micro mass spectrometer is one of the most powerful porta-ble analytical instruments. And the micro electron impact (EI) ionization source, which has crucial effects on micro mass spectrometer's performance, has been a research focus. In this study, a microplasma source as the electron source of the EI ionization source was developed to solve the difficulty in miniaturization on filament structure...
A new methodology is presented for three-dimensional (3D) computer simulations of realistic microstructures of particle-reinforced composites, through its application to the aluminum matrix composites reinforced with realistic complex SiC particles of highly variable and irregular angular geometries. It is followed by a finite element modeling for the microscopic and macroscopic mechanical behavior...
