Phase transitions as a collective response of an ensemble, with appearance of unique stable properties spontaneously, is critical to a variety of devices: electronic, magnetic, optical, and their coupled forms. This chapter starts with a discussion of broken symmetry and its manifestation in the property changes in thermodynamic phase transition and the Landau mean-field articulation. It then follows it with an exploration of different phenomena and their use in devices. The first is ferroelectricity—spontaneous electric polarization—and its use in ferroelectric memories. Electron correlation effects are explored, and then conductivity transition from electron-electron and electron-phonon coupling and its use in novel memory and device forms. This is followed by development of an understanding of spin correlations and interactions and magnetism—spontaneous magnetic polarization. The use and manipulation of the magnetic phase transition in disk drives, magnetic and spin-torque memory as well as their stability is explored. Finally, as a fourth example, amorphous-crystalline structural transition in optical, electronic, and optoelectronic form are analyzed. This latter’s application include disk drives and resistive memories in the form of phase-change as well as those with electochemical transport.

A striking difference between near-field optics and far-field optics is the possibility of breaking the so-called diffraction limit, namely of confining light to subwavelength spots. The first section of this chapter introduces the concept of evanescent waves to discuss the subwavelength confinement of light. One of the key ideas put forward is that the presence of charges is required to generate highly localized fields. It is thus necessary to have a tool to compute fields in the presence of these charges. With this aim, the concept of the Green tensor is introduced in the second section. This is a powerful tool for computing electromagnetic fields in inhomogeneous environments. It is also a key quantity for discussing the local density of states and therefore controlling spontaneous emission. The final section is devoted to an introduction to surface plasmons, which are very useful for manipulating electromagnetic fields at the nanoscale.

The discovery of new materials and the manipulation of their exotic properties for device fabrication is crucial for advancing technology. Nanoscience and the creation of nanomaterials have taken materials science and electronics to new heights for the benefit of mankind. Advanced Materials and Nanosystems: Theory and Experiment cover several topics of nanoscience research. The compiled chapters aim to update students, teachers, and scientists by highlighting modern developments in materials science theory and experiments. The significant role of new materials in future technology is also demonstrated. The book serves as a reference for curriculum development in technical institutions and research programs in the field of physics, chemistry, and applied areas of science like materials science, chemical engineering, and electronics. This part covers 12 topics in these areas: - Carbon and boron nitride nanostructures for hydrogen storage applications - Nanomaterials for retinal implants - Materials for rechargeable battery electrodes - Cost-effective catalysts for ammonia production - The role of nanocomposites in environmental remediation - Optical analysis of organic and inorganic components - Metal-oxide nanoparticles - Mechanical analysis of orthopedic implants - Advanced materials and nanosystems for catalysis, sensing, and wastewater treatment - Topological Nanostructures - Hollow nanostructures

“Periodization of Strength Training for Sports can be used as a guide for coaches as well as for athletes who want to reach their full potential and avoid overtraining and injuries. I designed my annual training plan according to this book, and it helped my 3×3 basketball team achieve a #1 world ranking.” —Darko Krsman, MSc, ISCI-SSC, CSCS, Strength and Conditioning Coach, Coach of FIBA’s Top-Ranked 3×3 Basketball Team “Periodization of Strength Training for Sports is a must-read book for coaches in all sports who want their athletes to reach maximum performance. This resource has helped me train national-level athletes to elite-level athletes.” —Lucian Nicolescu, Strength and Conditioning Coach for Elite Tennis Players and Track and Field Olympians, 2018 Strength and Conditioning Coach of the Year (Awarded by the International Strength and Conditioning Institute) Tudor Bompa revolutionized Western training methods when he introduced his groundbreaking theory of periodization. He is now a world-renowned exercise scientist and the foremost authority on periodization. In Periodization of Strength Training for Sports, Fourth Edition, Bompa partners with international strength and conditioning expert Carlo Buzzichelli to go beyond the simple application of bodybuilding or powerlifting programs to show you what training to schedule—and when—to build athletic strength and maximize performance at the right time. Periodization of Strength Training for Sports demonstrates how to use periodized workouts to peak at optimal times by manipulating strength training variables through six training phases—anatomical adaptation, hypertrophy, maximum strength, conversion to specific strength, maintenance, and peaking. Coaches and athletes in 30 sports now have at their fingertips proven programs that take into consideration the specific phases and unique demands of their sport, along with information about the dominant energy system, limiting factors for performance, and objectives for strength training. No more guessing about preseason conditioning, in-season workloads, or rest and recovery periods—now it’s simply a matter of implementing the strategies in this book. Rather than experiment with untested training regimens, let the ready-made training schedules and proven science in Periodization of Strength Training for Sports eliminate the guesswork and establish a clear path to achieving the best results at the ideal time.
