O- density measurements in the pulsed-DC reactive magnetron sputtering of titanium
The importance of electronegative species in technological plasmas is currently of great interest, both from a theoretical and experimental point of view, with much of the recent work concentrating on reactive ion etching discharges. However, other very important plasma systems have been somewhat neglected by scientist and engineers in terms of the role of negative ions, for instance, pulsed ...

Computational study of a diagonal channel Magnetohydrodynamic power generation
This paper studies the performance of a diagonal channel Magnetohydrodynamic (MHD) power generation. This system includes a diagonal conducting wall MHD generator. As a model of channel, we use a scramjet-driven MHD generator where the MHD generator is directly integrated into the propulsion system. The channel specification is 59.28 cm in length. The working plasma for the power system is ...

Plasma Arc Waste Destruction System (PAWDS) - A novel approach to waste elimination aboard ships
The Plasma Arc Waste Destruction System (PAWDS) uses plasma energy, with temperatures over 5,000 oC, to rapidly and efficiently destroy combustible waste aboard ships. PAWDS has proven itself to be a viable alternative to traditional incinerators. In September 2003, Carnival Cruise Lines were the first to install a PAWDS aboard their 2,056 passenger (plus 1,000 crew members) capacity, M/S ...

Fly Ash Treatment – Plasma Torches versus Graphite Electrodes
Background Plasma generating devices have to be designed to tolerate incredibly harsh conditions during operation and in particular very high heat loads and temperatures around the arc. However, when used in the vitrification of highly chlorinated materials the challenge is even greater than in other applications. The combination of high general furnace temperatures, extremely high local ...

Why Gas-Phase Dynamics are Central to Low-Pressure Plasma Applications
Low-pressure plasma applications are pivotal in the advancement of materials science and surface engineering. They offer unparalleled precision and control in the modification and synthesis of surface coatings and films. High Power Impulse Magnetron Sputtering (HiPIMS), Diamond-Like Carbon (DLC) coatings, plasma etching, Atomic Layer Deposition (ALD), and Pulsed Laser Deposition (PLD) coatings ...

Nonthermal Plasma Applications to the Environment: Gaseous Electronics and Power Conditioning
Abstract—For nearly two decades, interest in gas-phase pollution control has greatly increased, arising from a greater respect for the environment, more attention to the effects of pollution, and a larger body of regulations and laws. Nonthermal plasma (NTP) technology shows promise for destroying pollutants in gas streams and cleaning contaminated surfaces, using plasma-generated reactive ...

Feasibility analysis for biomass in cities, counties and facilities
The commercial waste industry includes all those who collect waste from the simplest “collect waste and transport to a landfill” to the more complex “collect waste and process into re-usable components and energy.” This article will cover how we can collect material and fuel a clean energy system for our immediate future, while saving clean water and air. Why Use Biomass? ...
