Tin (Sn) whiskers are electrically conductive, single crystal eruptions that grow from Sn film surfaces. Their high aspect ratio presents reliability problems for the electronics industry due to bridging and metal arcing, leading to malfunctions and catastrophic failures in many electronic systems (including satellite and defense sectors). Due to legislation in the EU, Japan, and the U.S., mandating a gradual shift from lead (Pb)-based to lead-free solders and board finishes, there has been a reemergence of Sn whiskers. Continuing reports of Sn whisker induced failures coupled with the lack of an industry-accepted understanding of whisker growth and/or test methods to identify whisker prone products has made pure/high Sn substitutes a risky proposition in high reliability systems. This thesis is designed to clarify and control the fundamental mechanisms that govern whisker formation. The research focuses on reproducible "laboratory" created whiskers under a variety of rigorously controlled environmental factors such as film thickness, film stress, substrate material, gas environment, and humidity exposure, which are known to play a significant role in whisker production. The ultimate question of how to impede and/or prevent whisker growth is also addressed and shows that whisker prevention is possible via hard metal capping films, which are impenetrable by whiskers.

Photonic crystal fibers, also known as microstructured or holey fibers, have recently generated great interest in the scientific community thanks to the new ways provided to control and guide light, not obtainable with conventional optical fibers. Proposed for the first time in the 90’s, photonic crystal fibers have driven an exciting and irrepressible research activity all over the World, starting in the telecommunication field and then touching metrology, spectroscopy, microscopy, astronomy, micromachining, biology and sensing. This book is intended to provide an expert guidance through the properties of photonic crystal fibers, with a specific focus on the telecommunication aspects. The authors believe that photonic crystal fibers can revolutionize the field of guided optics and its applications, especially when considering signal processing and specific functions rather than the usage in long distance transmission. They provide a deep analysis of how the physical and geometrical characteristics of these new fibers can be tailored to achieve the goal of ad hoc performances, using the powerful numerical approach of the finite element method, and keeping in mind the possibilities and limits of photonic crystal fiber fabrication technology. The book will thus benefit researchers with an interest to explore this field of telecommunication, looking at current as well as emerging applications.

Sensorimotor integration, the dynamic process by which the sensory and motor systems communicate with each other, is crucial to humans’ and animals’ ability to explore and react to their environment. This book summarizes the main aspects of our current understanding of sensorimotor integration in 10 chapters written by leading scientists in this active and ever-growing field. This volume focuses on the whisker system, which is an exquisite model to experimentally approach sensorimotor integration in the mammalian brain. In this book, authors examine the whisker system on many different levels, ranging from the building blocks and neuronal circuits to sensorimotor behavior. Neuronal coding strategies, comparative analysis as well as robotics illustrate the multiple facets of this research and its broad impact on fundamental questions about the neurobiology of the mammalian brain.

Active (also called “smart”) coatings and thin films are defined as those that are capable of sensing their environment and appropriately responding to that external stimulus. This Special Issue “Active Organic and Organic-Inorganic Hybrid Coatings and Thin Films: Challenges, Developments, Perspectives” collected a series of papers that outline the current frontiers in the development of smart coatings and thin films for corrosion and other types of materials applications. The first four papers focus on novel discoveries on coatings with corrosion protection properties. These include environmentally-friendly polyurethane loaded with cerium nitrate corrosion inhibitor for mild steel protection, hot-pressed organic polymer coatings for the protection of pre-treated aluminum alloy surfaces exposed to NaCl aqueous solutions, functional epoxy coating with modified functional TiO2 for steel substrates protection, and hybrid composites against the thermo-oxidative corrosion of the metal parts of the internal combustion engines, turbines, and heaters. The next paper explores the potential of organic polymer/ceramic composite coatings to enhance the scratch resistance of typical floor laminates. The next three papers highlight other types of smart coatings and thin films, including low-temperature curable hybrid dielectric materials for field-effect transistors, bilayer antireflective coatings for optoelectronic devices, and organic polymers as the thin-film component for enthalpy exchanger systems in air conditioning applications. The final two papers focus on important research specific to coatings that serve as protection and preservation cultural heritage materials.
