This exploratory textbook starts with fundamentals that satisfy the needs of a diverse group of educators, researchers and students aspiring to engage in research and engineering of nanomaterials. It bridges the gap between undergraduate students in science and engineering who have not yet chosen a specific career path, graduate students still considering different disciplines and the cross-cutting scientific topics in nanomaterials. It extends to methods of common practice in the field, spanning experimental, and theoretical techniques. The extensive use of nanomaterials, such as carbon nanotubes, in the future of global technological solutions underscores the relevance of this text aimed at students and researchers with a range of interests. “Advances in Nanomaterials: Fundamentals, Properties and Applications,” is ideal for senior undergraduate and graduate students, faculty and general science enthusiasts interested in nanomaterials across contexts ranging from solar energy, structural engineering, to medical devices, to semiconductors. Guides readers from the fundamental principles of science required as background knowledge for nanomaterials; Enriches readers with the latest developments from research on nanomaterials; Introduces readers to common jargon with simplified explanation and illustrations, enabling them to follow state-of-the-art advances published in the archival literature; Provides a thorough overview of common nanomaterial synthesis, characterization and measurement methods, making the text a good reference for advanced undergraduate and graduate students; Includes practical examples, references and future perspectives to familiarize readers with challenges and trade-offs encountered in actual R&D.

This thesis provides an innovative strategy for rail crack monitoring using the acoustic emission (AE) technique. The field study presented is a significant improvement on laboratory studies in the literature in terms of complex rail profile and crack conditions as well as high operational noise. AE waves induced by crack propagation, crack closure, wheel-rail impact and operational noise were obtained through a series of laboratory and field tests, and analyzed by wavelet transform (WT) and synchrosqueezed wavelet transform (SWT). A wavelet power-based index and the enhanced SWT scalogram were sequentially proposed to classify AE waves induced by different mechanisms according to their energy distributions in the time–frequency domain. A novel crack sizing method taking advantage of crack closure-induced AE waves was developed based on fatigue tests in the laboratory. The propagation characteristics of AE waves in the rail were investigated, and Tsallis synchrosqueezed wavelet entropy (TSWE) with time was finally brought forward to detect and locate rail cracks in the field. The proposed strategy for detection, location and sizing of rail cracks helps to ensure the safe and smooth operation of the railway system. This thesis is of interest to graduate students, researchers and practitioners in the area of structural health monitoring.
