Metallic glasses are multi-component metallic alloys with disordered atomic distributionunlike their crystalline counterparts with long range periodicity in arrangement of atoms.Metallic glasses of different compositions are being commercially used in bulk form andas coatings because of their excellent corrosion resistance. This book was written withthe objective of providing a comprehensive understanding of the electrochemical andcorrosion behavior of metallic glasses for a wide range of compositions. Corrosion instructural materials leads to rapid deterioration in the performance of critical componentsand serious economic implications including property damage and loss in human life.Discovery and development of metallic alloys with enhanced corrosion resistance willhave a sizable impact in a number of areas including manufacturing, aerospace, oil andgas, nuclear industry, and load-bearing bioimplants. The corrosion resistance of manymetallic glass systems is superior compared to conventionally used alloys in different environments. In this book, we discuss in detail the role of chemistry, processing conditions,environment, and surface state on the corrosion behavior of metallic glasses and comparetheir performance with conventional alloys. Several of these alloy systems consist of allbiocompatible and non-allergenic elements making them attractive for bioimplants, stents,and surgical tools. To that end, critical insights are provided on the bio-corrosion responseof some metallic glasses in simulated physiological environment.

Plasma can be generated via the combination of energy-inducing fragmentation, ionization, and excitation of molecular. Such processes occur throughout the life of the plasma, resulting in a wide variety of atomic and molecular species, which can be electrically charged, energetically excited, highly reactive, or any combination of these states. Plasma diagnostics can demonstrate important discharge characteristics and the mechanisms of plasma-induced processes. Parameter’s dynamic range spans many orders of magnitude, and spatial/temporal scales significantly vary during plasma source configurations. Many diagnostic techniques have been developed to characterize plasma, including scattering techniques, intensified charge-coupled device cameras, laser-based methods, optical emission spectroscopy, mass spectrometry, electron paramagnetic resonance spectroscopy, gas chromatography, etc. Although various mature diagnostic technologies for plasma discharges have been developed, there are still many challenges. The measurement precision is not only affected by the diagnostic equipment/ techniques, but also by the plasma discharge itself. In many applications, direct measurements of the parameters of interest are still not possible. In addition, the plasma environments in application processes are unusually complex, and their reactions are still not fully understood. Plasma can exist in a variety of forms due to discharge modes resulting from different means of creation, resulting in a wide range of applications. This brings together many research fields, including physics, engineering, chemistry, biology, and medicine.
