Atmospheric-pressure plasmas continue to attract considerable research interest due to their diverse applications, including high power lasers, opening switches, novel plasma processing applications and sputtering, EM absorbers and reflectors, remediation of gaseous pollutants, excimer lamps, and other noncoherent light sources. Atmospheric-pressure plasmas in air are of particular importance as they can be generated and maintained without vacuum enclosure and without any additional feed gases. Non-Equilibrium Air Plasmas at Atmospheric Pressure reviews recent advances and applications in the generation and maintenance of atmospheric-pressure plasmas. With contributions from leading international researchers, the coverage includes advances in atmospheric-pressure plasma source development, diagnostics and characterization, air plasma chemistry, modeling and computational techniques, and an assessment of the status and prospects of atmospheric-pressure air plasma applications. The extensive application sections make this book attractive for practitioners in many fields where technologies based on atmospheric-pressure air plasmas are emerging.
We have provided experimental evidence that nanoparticles in plasma are heated to temperatures that are significantly higher than that of the background gas. This result gives experimental confirmation to a number of theoretical/computational studies that predicted this behavior. Moreover, this study has provided with the first measurement of the temperature of nanoparticles in a processing dusty plasma, i.e. under conditions that are relevant for the growth and modification of nanopowders.
This authoritative reference presents a comprehensive review of the evolution of plasma science and technology fundamentals over the past five decades. One of this field’s principal challenges has been its multidisciplinary nature requiring coverage of fundamental plasma physics in plasma generation, transport phenomena under high-temperature conditions, involving momentum, heat and mass transfer, and high-temperature reaction kinetics, as well as fundamentals of material science under extreme conditions. The book is structured in five distinct parts, which are presented in a reader-friendly format allowing for detailed coverage of the science base and engineering aspects of the technology including plasma generation, mathematical modeling, diagnostics, and industrial applications of thermal plasma technology. This book is an essential resource for practicing engineers, research scientists, and graduate students working in the field.
Cold atmospheric plasma (CAP) emerges as a possible new modality for cancer treatment. This book provides a comprehensive introduction into fundamentals of the CAP and plasma devices used in plasma medicine. An analysis of the mechanisms of plasma interaction with cancer and normal cells including description of possible mechanisms of plasma selectivity is included. Recent advances in the field, the primary challenges and future directions are presented.
Research during this past year has emphasized studies of plasmas properties and associated diagnostics, including nonequilibrium effects in so-called thermal plasmas. The present report discusses first measurements of the radiative source strength of air for temperatures in the range between 5000 and 7500K. To our knowledge these are the first measurements of this important property in this temperature range. The results are compared with a NASA computer code. Also described is a study of quenching effects on excited states of a nonequilibrium thermal plasma. These and companion measurements show that the common assumption of local thermodynamic equilibrium in plasmas at or about atmospheric pressure can be seriously in error and that as a result the reliability of many temperature measurements in such plasmas should be questioned. Contents: Measurements of the volumetric radiative source strength of an air plasma between 5000 and 7500K; and Electronic quenching of argon excited states in a non-equilibrium plasma at atmospheric pressure.
The Sun as a Guide to Stellar Physics illustrates the significance of the Sun in understanding stars through an examination of the discoveries and insights gained from solar physics research. Ranging from theories to modeling and from numerical simulations to instrumentation and data processing, the book provides an overview of what we currently understand and how the Sun can be a model for gaining further knowledge about stellar physics. Providing both updates on recent developments in solar physics and applications to stellar physics, this book strengthens the solar–stellar connection and summarizes what we know about the Sun for the stellar, space, and geophysics communities. Applies observations, theoretical understanding, modeling capabilities and physical processes first revealed by the sun to the study of stellar physics Illustrates how studies of Proxima Solaris have led to progress in space science, stellar physics and related fields Uses characteristics of solar phenomena as a guide for understanding the physics of stars
