Handbook of Self-Cleaning Surfaces and Materials: From Fundamentals to Applications: Volumes 1 and 2 2023.1 （ ISBN:9783527351367 ）

In this chapter, we introduce two types of superhydrophobic films formed on AZ31 magnesium alloy. One was fabricated by plasma chemical vapor deposition (CVD), and the other was prepared by two-step immersion processes. These film surfaces showed a static water contact angle of more than 150°. The hydrophobicity and root mean square roughness of the film surface increased with an increase in deposition or immersion time. The durability of these superhydrophobic surfaces in corrosive 5 wt% NaCl aqueous solution was elucidated. The anticorrosion resistance of these films was estimated by potentiodynamic polarization curve and electrochemical impedance spectroscopy (EIS) measurements. The EIS measurements and appropriate equivalent circuit models revealed that these superhydrophobic films considerably improved the anticorrosion-resistant performance of magnesium alloy AZ31. The anticorrosion mechanism of these superhydrophobic films was also proposed.

Solution plasma processing is a bottom-up synthetic approach that can be employed for directly preparing nitrogen-doped carbons from single-source precursors with in situ nitrogen doping. Research efforts and interest in this topic have gained at a significant pace over the past years. This chapter provides an overview of solution plasma processing and recent progress on the synthesis of nitrogen-doped carbons from single-source precursors using this approach. The chapter starts by introducing the basic fundamentals of solution plasma and how to apply it in the synthesis of nitrogen-doped carbons. The effects of a solution plasma conditions and the type of precursors on the overall properties of nitrogen-doped carbons are summarized based on the important findings reported in the literature. A potential application of nitrogen-doped carbons as metal-free electrocatalysts for oxygen reduction reaction is explained and discussed in brief. At the end of the chapter, the remaining challenges and future prospects are highlighted for use in further studies. This chapter is intended to be generally informative and a useful guide for researchers who are new to this field.

Solution plasma reactions and materials synthesis

Panomsuwan G., Ueno T., Yui H., Nakamura J., Saito N.

Molecular Technology: Energy Innovation 2018.12 （ ISBN:9783527345885 ）

Electrical discharge in liquid, termed as solution plasma (SP), has become a booming research interest in the area of materials synthesis and processing owing to its flexible use of liquid mediums, which creates various reactive species and novel reaction fields. This successful approach has paved the way to designing and exploring novel materials for a broader field of applications. This chapter presents an overview of SP and its overall progress in materials synthesis and processing from the past to present, which is classified by the type of materials (metal nanoparticles, metal oxide, carbon materials, composites, etc.). Furthermore, current trend and future challenges of SP in both experimental and theoretical aspects are proposed as guidelines for further development and study. We expect that this chapter will serve as a valuable and handy reference for researchers who are studying SP and multidisciplinary fields of materials science and nanotechnology.
