cold plasma การใช้

• I know you can get cold plasmas but I just assumed that plasma was hot.
• There are also cold plasmas, usually generated inside vacuum chambers, at low pressure regimes.
• The cold plasma plume emitted by the plasma pencil can be used to kill bacteria without harming skin tissue.
• Cold plasma machines utilize pure oxygen as the input source and produce a maximum concentration of about 5 % ozone.
• However, because cold plasma ozone generators are very expensive, they are found less frequently than the previous two types.
• :: : Specifically, it's a type of cold plasma, which have a low percentage of ionized atoms.
• Warm plasma would have been a better term, since ultra-cold plasma could then be simply called cold plasma, but we are stuck with the terms we have.
• Warm plasma would have been a better term, since ultra-cold plasma could then be simply called cold plasma, but we are stuck with the terms we have.
• The relatively cold plasma in the innermost region of Saturn's magnetosphere, inside 3 R s ( near the rings ) consists mainly of O + and O 2 + ions.
• Nonequilibrium plasma ( cold plasma ) can be generated under atmospheric conditions at very high frequencies or using short duration microdischarges created by dielectric breakdown between two electrodes separated by an insulating dielectric barrier.
• These drifts, in contrast to the mirror effect and the non-uniform " B " drifts, do not depend on finite Larmor radius, but are also present in cold plasmas.
• Some cold plasma units also have the capability of producing short-lived allotropes of oxygen which include O 4, O 5, O 6, O 7, etc . These species are even more reactive than ordinary.
• A relativistic plasma with a thermal relativistic beam impacting some target . ( More mundanely, " relativistic plasma " might denote a normal, cold plasma moving at a significant fraction of the speed of light relative to the observer .)
• Looking at it from the other side, any measured " I-V " characteristic can be interpreted as a hot plasma, where most of the voltage is dropped in the Debye sheath, or as a cold plasma, where most of the voltage is dropped in the bulk plasma.
• Once the balloon is in the ionosphere or thermosphere, buoyancy will be an insignificant force, and thermal interactions will become insignificant ( although, a balloon of near-infinite volume might have sufficient number of thermal collisions to break down our cold plasma assumptions . . . ) talk ) 23 : 24, 4 June 2009 ( UTC)
• Amongst these are the generation of large volume low temperature plasmas, the interaction of microwaves with plasmas, and the biomedical applications of cold plasmas, a field known as  National Geographic ( February 2006 issue ), ABC online news, and was featured in a couple of science / technology shows on the History Channel and the Smithsonian Channel.
• In the ignited ( or  arc ) mode the plasma is maintained via ionization internally by hot plasma electrons ( ~ 3300 K ); in the unignited mode the plasma is maintained via injection of externally produced positive ions into a cold plasma; in the hybrid mode the plasma is maintained by ions from a hot-plasma interelectrode region transferred into a cold-plasma interelectrode region.
