Measures against leakage current and spike noise through the control of the aluminum oxide film on the collecting electrode.
S30572
Optimization of anodic oxidation films through the combination of crystalline materials and electrolytes.
【Lecture Summary】 The dense oxide film formed by anodic oxidation on metal surfaces, represented by aluminum, has garnered attention for its high controllability due to electrolytic conditions, and its functionality is also being anticipated for use in capacitors and battery materials. This lecture will explain the generation behavior, structure, and properties of the film from a fundamental perspective. 【Lecture Summary】 In recent years, starting in Europe and now spreading to Japan, diesel engine passenger cars have been named "clean diesel" and are becoming more popular. This lecture will clarify why diesel engines are currently attracting attention and how they differ from the previous generation of diesel engines that once declined, through an explanation of the latest engine systems and exhaust gas treatment technologies.
