future devices.

Nanowires are attracting wide scientific interest due to the unique properties associated with their one-dimensional geometry. Nanowires, with diameters reaching the quantum re‐ gime, have been the focus of research for several decades and remain at the forefront of both scientific research and developing nanotechnology applications. The benefits of 1D proper‐ ties lie in various applications for future quantum devices, nanoelectronics, nanophotonics, nanobiointerfaces, and energy harvesting. Developments in the understanding of the funda‐ mental principles of nanowire growth mechanisms and mastering functionalization provide tools to control crystal structure, morphology, and interactions at the material interface, and create characteristics that are superior to those of planar geometries. This book provides a comprehensive overview of the most important developments in the field of nanowires,

The book consists of two parts: the first is devoted to the synthesis of nanowires and charac‐ terization, and the second investigates the properties of nanowires and their applications in

The synthesis and characterization section starts with Chapter 1 dealing with nanowires of tunneling magnetoresistance (TMR) synthesis and characterization. Nanowires of Fe/MgO/Fe encapsulated in carbon nanotubes were synthesized using glancing angle depo‐ sition. Nanowires of TMR were synthesized using magnetron DC/RF sputtering by filling Fe/MgO/Fe inside vertically grown and substrate-supported carbon nanotubes. TMR is a macroscopic quantum phenomenon that allows electrical current to flow across an insulator between two electrodes with the application of an external magnetic field. The coherent TMR effect is paramount in making spintronic devices. Changing the geometry from planar trilayer nanometric thin film to a nanowire with cylindrical geometry of nanometric diame‐

A review of diamond nanowire (DNW) synthesis methods is given in Chapter 2. Due to su‐ perior hardness, Young's modulus, and biocompatibility, optical and fluorescence nanodia‐ mond seems to be outstanding among carbon nanomaterials. The development of DNW is known to be a significantly innovative field due to its diverse applications such as sensors, semiconductors, and electrochemical utilities. However, DNW synthesis in a reproducible way is still a challenging task. Detailed studies on DNW structures may help researchers to use them in diverse applications. In this chapter , up-to-date applications of DNW along

Chapter 3 is dedicated to the synthesis of LiMn2O4 nanowires and their application as a bat‐ tery cathode material. Nanowires offer the following advantages: large surface-to-volume ratio, efficient electron conducting pathways, and facile strain relaxation. To enhance activi‐
