With this volume, Ezequiel P. M. Leiva and co-authors fill a gap in the available literature, by providing a much-needed, comprehensive review of the relevant literature for electrochemists, materials scientists and energy researchers. For the first time, they present applications of underpotential deposition (UPD) on the nanoscale, such as nanoparticles and nanocavities, as well as for electrocatalysis. They also discuss real surface determinations and layer-by-layer growth of ultrathin films, as well as the very latest modeling approaches to UPD based on nanothermodynamics, statistical mechanics, molecular dynamics and Monte-Carlo simulations.

This thesis presents various applications of graphene-based nanomaterials, especially in biomedicine. Graphene and its derivatives have gained enormous attention from scientists in all fields of study due to many unprecedented properties. The initial scientific attention was focused on the development of transparent flexible electrodes by exploiting two-dimensional graphene film's extraordinary electrical and physical properties. Recently, given an increasing evidence of dispersed graphene-based nanomaterials' biocompatibility, researchers have endeavored to employ these materials in other studies relevant to biomedical technologies. In this respect, the thesis provides a comprehensive review on the synthesis, toxicity, and a few of the key biomedical applications in the first chapter. The following chapter discusses the use of a graphene film as a novel catalyst to oxidatively destroy phenols, which are known to be potentially mutagenic and carcinogenic. Finally, and most importantly, the last chapter introduces the therapeutic role of graphene quantum dots, the smallest graphene-based nanomaterials, for Parkinson's disease. The results are promising for the use of graphene quantum dots as the basis of future clinical drug candidates for neurodegenerative disorders.

This fabrication technology has been systematically investigated by using experimental measurements, mechanism analyses, theoretical simulations and so on. Three common materials (i.e., silicon, PDMS and Parylene-C) with micro/nano hierarchical structures have been successfully fabricated, which also show several attractive properties. Furthermore, this book introduces this fabrication technology into microenergy field, and proposes several high-performance nanogenerators, of which practical applications have also been studied in commercial electronic device and biomedical microsystem.

This book presents the topology optimization theory for laminar flows with low and moderate Reynolds numbers, based on the density method and level-set method, respectively. The density-method-based theory offers efficient convergence, while the level-set-method-based theory can provide anaccurate mathematical expression of the structural boundary. Unsteady, body-force-driven and two-phase properties are basic characteristics of the laminar flows. The book discusses these properties, which are typical of microfluidics and one of the research hotspots in the area of Micro-Electro-Mechanical Systems (MEMS), providing an efficient inverse design approach for microfluidic structures. To demonstrate the applications of this topology optimization theory in the context of microfluidics, it also investigates inverse design for the micromixer, microvalve and micropump, which are key elements in lab-on-chip devices.

This book provides a new direction in electronics research with the invention of a new material tuPOY, which changes our perception of developing electronics. Evolving on a relatively underplayed phenomenon of static electricity in scientific exploration and application, tuPOY upholds the potential to rival both silicon and metals as electronics of the future. Devices made of tuPOY present a new emblem to the technological world, where we could envision our electronic paraphernalia from a completely different perspective. A computer the size of a big wall, which could be neatly folded and kept in our pockets when not in use and laundered on a regular basis, can be imagined possible with this invention. The concept, manufacturing process, physics and uses of tuPOY as the next generation material of electronics is described in this book. The book covers the production process of tuPOY and goes on to conceptual advancement from manipulating the sensing, radiating and processing properties of tuPOY. Theoretical modelling of tuPOY is characterized by steady-state equations exploiting interchanges based on the lattice kinetics, which mathematizes an Interchange Phenomenon in tuPOY. The numerical manifestations calibrate mathematically, tuPOY's response to any external physical impetus such as charge, heat or energy flow. The book validates the sensing properties and theoretical model by designing a tuPOY sensor which can be used in a plethora of applications. A novel microstrip antenna is designed by amalgamation of tuPOY, raw silk and polynylon composites to experimentally verify the radiation properties of the new material. The conduction properties are verified by drawing fibres of tuPOY and using them as wires and connectors in electronics. A Power Generating Unit (PGU) is designed with tuPOY as its primary element. This is a first of its kind PGU that scavenges power from thermal energy presenting a new dimension in operational power dynamics. Overall this book should be of interest to a wide range of readers ranging from researchers, scientists, developers, manufacturers, engineers, graduate students and anyone who has satiety to think differently.

Starting from a broad overview of heat transport based on the Boltzmann Transport Equation, this book presents a comprehensive analysis of heat transport in bulk and nanomaterials based on a kinetic-collective model (KCM). This has become key to understanding the field of thermal transport in semiconductors, and represents an important stride. The book describes how heat transport becomes hydrodynamic at the nanoscale, propagating very much like a viscous fluid and manifesting vorticity and friction-like behavior. It introduces a generalization of Fourier's law including a hydrodynamic term based on collective behavior in the phonon ensemble. This approach makes it possible to describe in a unifying way recent experiments that had to resort to unphysical assumptions in order to uphold the validity of Fourier's law, demonstrating that hydrodynamic heat transport is a pervasive type of behavior in semiconductors at reduced scales.

This book provides essential insights into designing a localized DNA circuit to promote the rate of desired hybridization reactions over undesired leak reactions in the bulk solution. The area of dynamic DNA nanotechnology, or DNA circuits, holds great promise as a highly programmable toolbox that can be used in various applications, including molecular computing and biomolecular detection. However, a key bottleneck is the recurring issue of circuit leakage. The assembly of the localized circuit is dynamically driven by the recognition of biomolecules - a different approach from most methods, which are based on a static DNA origami assembly. The design guidelines for individual reaction modules presented here, which focus on minimizing circuit leakage, are established through NUPACK simulation and tested experimentally - which will be useful for researchers interested in adapting the concepts for other contexts. In the closing section, the design concepts are successfully applied to the biomolecular sensing of a broad range of targets including the single nucleotide mutations, proteins, and cell surface receptors.

This thesis focuses on the transport and magneto-transport properties of graphene p-n-p junctions, such as the pronounced quantum Hall effect, a well-defined plateau-plateau transition point, and scaling behavior. In addition, it demonstrates persistent photoconductivity (PPC) in the monolayer MoS2 devices, an effect that can be attributed to random localized potential fluctuations in the devices. Further, it studies scaling behavior at zeroth Landau level and high performance of fractional values of quantum Hall plateaus in these graphene p-n-p devices. Moreover, it demonstrates a unique and efficient means of controlling the PPC effect in monolayer MoS2. This PPC effect may offer novel functionalities for MoS2-based optoelectronic applications in the future.

This book deals with mathematical modeling, namely, it describes the mathematical model of heat transfer in a silicon cathode of small (nano) dimensions with the possibility of partial melting taken into account. This mathematical model is based on the phase field system, i.e., on a contemporary generalization of Stefan-type free boundary problems. The approach used is not purely mathematical but is based on the understanding of the solution structure (construction and study of asymptotic solutions) and computer calculations. The book presents an algorithm for numerical solution of the equations of the mathematical model including its parallel implementation. The results of numerical simulation concludes the book. The book is intended for specialists in the field of heat transfer and field emission processes and can be useful for senior students and postgraduates.

This book presents research dedicated to solving scientific and technological problems in many areas of electronics, photonics and renewable energy. Energy and information are interconnected and are essential elements for the development of human society. Transmission, processing and storage of information requires energy consumption, while the efficient use and access to new energy sources requires new information (ideas and expertise) and the design of novel systems such as photovoltaic devices, fuel cells and batteries. Semiconductor physics creates the knowledge base for the development of information (computers, cell phones, etc.) and energy (photovoltaic) technologies. The exchange of ideas and expertise between these two technologies is critical and expands beyond semiconductors. Continued progress in information and renewable energy technologies requires miniaturization of devices and reduction of costs, energy and material consumption. The latest generation of electronic devices is now approaching nanometer scale dimensions, new materials are being introduced into electronics manufacturing at an unprecedented rate, and alternative technologies to mainstream CMOS are evolving. Nanotechnology is widely accepted as a source of potential solutions in securing future progress for information and energy technologies. Semiconductor Nanotechnology features chapters that cover the following areas: atomic scale materials design, bio- and molecular electronics, high frequency electronics, fabrication of nanodevices, magnetic materials and spintronics, materials and processes for integrated and subwave optoelectronics, nanoCMOS, new materials for FETs and other devices, nanoelectronics system architecture, nano optics and lasers, non-silicon materials and devices, chemical and biosensors, quantum effects in devices, nano science and technology applications in the development of novel solar energy devices, and fuel cells and batteries.

This book provides a comprehensive introduction to ferroics and frustrated materials. Ferroics comprise a range of materials classes with functionalities such as magnetism, polarization, and orbital degrees of freedom and strain. Frustration, due to geometrical constraints, and disorder, due to chemical and/or structural inhomogeneities, can lead to glassy behavior, which has either been directly observed or inferred in a range of materials classes from model systems such as artificial spin ice, shape memory alloys, and ferroelectrics to electronically functional materials such as manganites. Interesting and unusual properties are found to be associated with these glasses and have potential for novel applications. Just as in prototypical spin glass and structural glasses, the elements of frustration and disorder lead to non-ergodocity, history dependence, frequency dependent relaxation behavior, and the presence of inhomogeneous nano clusters or domains. In addition, there are new states of matter, such as spin ice; however, it is still an open question as to whether these systems belong to the same family or universality class. The purpose of this work is to collect in a single volume the range of materials systems with differing functionalities that show many of the common characteristics of geometrical frustration, where interacting degrees of freedom do not fit in a lattice or medium, and glassy behavior is accompanied by additional presence of disorder. The chapters are written by experts in their fields and span experiment and theory, as well as simulations. Frustrated Materials and Ferroic Glasses will be of interest to a wide range of readers in condensed matter physics and materials science.
