Providing a fundamental introduction to all aspects of modern plasma chemistry, this book describes mechanisms and kinetics of chemical processes in plasma, plasma statistics, thermodynamics, fluid ...mechanics and electrodynamics, as well as all major electric discharges applied in plasma chemistry. Fridman considers most of the major applications of plasma chemistry, from electronics to thermal coatings, from treatment of polymers to fuel conversion and hydrogen production and from plasma metallurgy to plasma medicine. It is helpful to engineers, scientists and students interested in plasma physics, plasma chemistry, plasma engineering and combustion, as well as chemical physics, lasers, energy systems and environmental control. The book contains an extensive database on plasma kinetics and thermodynamics and numerical formulas for practical calculations related to specific plasma-chemical processes and applications. Problems and concept questions are provided, helpful in courses related to plasma, lasers, combustion, chemical kinetics, statistics and thermodynamics, and high-temperature and high-energy fluid mechanics.
Maddenin dördüncü hali olan plazmayı kullanan atmosferik basınçlı plazma işlemi otomotivde boyanabilirlik ve yapışma, tekstilde nem tutma, hava geçirgenliği, ağırlık azaltma ve kir iticilik, ...gıdalarda bakteri inaktivasyonu ve tıpta iyileştirme hızlandırma gibi birçok alanda kullanılmaktadır. Atmosferik basınçlı plazmanın (ABP) polimerler üzerinde kullanılması yüzey modifikasyonu, yüzey aktivasyonu sağlaması, yüzey temizliği gibi avantajlara sahip olması, pek çok kombinasyonu olması ve parametrelerinin (güç, gaz akış debisi vb.) kontrolü ile beklenen özellikleri sağlaması nedeniyle önemli ve popülerliği artan bir konudur. Bu derleme çalışmasında atmosferik basınçlı plazma hakkında genel bilgiler verildikten sonra özellikle polipropilen (PP) malzeme üzerinde atmosferik basınçlı plazma yönteminin uygulamaları örneklenmiş ve benzer alanlarda yapılan çalışmalarla karşılaştırmalar yapılmıştır.
Kako bi se utvrdila promjena obojenja odn. postojanost obojenja, uzorak vegetabilno štavljene kože podvrgnut je močenju u alkalnoj otopini znoja kako bi se izlučio višak tanina i drugih netaninskih ...tvari koje zbog svoje velike količine unutar stukture kože imaju snažan antimikrobni učinak, te u tom slučaju naknadna obrada nije potrebna. Remisijskim spektrofotometrom uzorci kože snimljeni su prije i nakon procesa močenja kako bi se utvrdila promjena obojenja objektivnim mjerenjem kolorističkih prametara boje i ukupne razlike u boji. Učinkovitost obrada ekološki prihvatljivom plazmom i biopolimerom hitozanom potvrđena je kod nekih uzoraka kože mikrobiološkim analizama spram dvije bakterijske vrste Staphylococcus aureus i Klebsiella pneumoniae, provedbom kvalitativnog testa difuzije.

This rigorous explanation of plasmas is relevant to diverse plasma applications such as controlled fusion, astrophysical plasmas, solar physics, magnetospheric plasmas, and plasma thrusters. More ...thorough than previous texts, it exploits new powerful mathematical techniques to develop deeper insights into plasma behavior. After developing the basic plasma equations from first principles, the book explores single particle motion with particular attention to adiabatic invariance. The author then examines types of plasma waves and the issue of Landau damping. Magnetohydrodynamic equilibrium and stability are tackled with emphasis on the topological concepts of magnetic helicity and self-organization. Advanced topics follow, including magnetic reconnection, nonlinear waves, and the Fokker–Planck treatment of collisions. The book concludes by discussing unconventional plasmas such as non-neutral and dusty plasmas. Written for beginning graduate students and advanced undergraduates, this text emphasizes the fundamental principles that apply across many different contexts.
