Experimental Study on Dust Removal Performance of Electrostatic Water Film Cyclone Dust Collector
International Journal of Rotating Machinery, 2023 Due to their limitations, conventional electric and water film dust removal methods struggle to handle fine dust. This study presented information on and examined the electrostatic water film cyclone dust collector (EWFCDC). By using the variable control

Transition from tunneling to direct contact in tungsten nanojunctions [PDF]
, 2003 We apply the mechanically controllable break junctions technique to investigate the transition from tunneling to direct contact in tungsten. This transition is quite different from that of other metals and is determined by the local electronic properties

The promotion effect of uniaxial strain on hydrogen aggregation in tungsten
Frontiers in Materials, 2023 The aggregation behavior of hydrogen (H) isotopes after low-energy plasma irradiation is particularly important for tungsten (W) in future fusion devices. Here, using the first-principles calculation, we demonstrated an interesting strain effect that may

Optical properties of tungsten thin films perforated with a bidimensional array of subwavelength holes [PDF]
, 2003 We present a theorical investigation of the optical transmission of a dielectric grating carved in a tungsten layer. For appropriate wavelengths tungsten shows indeed a dielectric behaviour.
