In recent decades, metrologyΓÇöan accurate and precise technology of high quality for automotive enginesΓÇöhas garnered a great deal of scientific interest due to its unique advanced soft engineering techniques in design and diagnostics. Used in a variety of scientific applications, these techniques are now widely regarded as safer, more efficient, and more effective than traditional ones. This book compiles and details the cutting-edge research in science and engineering from the Egyptian Metrology Institute (National Institute for Standards) that is revolutionizing advanced dimensional techniques through the development of coordinate and surface metrology.

Nanobiophysics is a new branch of science that operates at the interface of physics, biology, chemistry, material science, nanotechnology, and medicine. This book is the first one devoted to nanobiophysics and introduces this field with a focus on some selected topics related to the physics of biomolecular nanosystems, including nucleosomal DNA and model lipid membranes, nanobiohybrids involving DNA/RNA and single-walled carbon nanotubes, biomolecules deposited on nanoparticles, and nanostructured surfaces. It describes unique experimental physical methods that are used to study nanosized biostructures. It outlines the applied aspects of nanobiophysics, considering the state of art in the fabrication of two types of sensors: gas sensors, with a focus on breath gas detection, and nanophotonic sensors, with a focus on polycyclic aromatic hydrocarbon detection in water samples. It also covers the development of nanoscale scaffolds for delivery of therapeutic nucleic acids to cells, which is an important example of the possible application of nanobiophysics researches in nanomedicine.

This book bridges the gap between preparation of hydrogels, which is often discussed in books and reviews, and their characterization techniques. It aims to offer graduate students as well as researchers, including PhD students and those involved in R&D in pharmaceutical companies and academia, a valid support that can help them find appropriate keys to open the doors to the complex world of polysaccharide hydrogels. The first part of the book gives a wide overview of the most important approaches for the physicochemical characterization of hydrogels while the second one is mainly devoted to biomedical applications.

This book is for readers with some background in science, concerning the search for drugs, starting from molecular diversity in nature or molecular wilderness. It differs from those available on the subject of natural products and drugs derived therefrom in that it looks at the broad picture on how materials and organisms from nature affect our health and how we have combined our knowledge in chemistry, biology, and biodiversity to promote our wellness from resources in the "molecular wilderness," with caveats on sustainable utilization of these resources.

This book provides a comprehensive yet deep and wide description of DC-DC switching power supply circuits, to which much attention is being paid as a key technology in green IT, especially in automotive and consumer electronics industry. It covers buck converters, isolated converters, PFC converters, their modeling and analysis, several control methods, passive components, and their several recent applications (on-chip power supplies, DC-DC and AC-DC converter applications, single-inductor multi-output DC-DC converters, energy harvest applications, wireless power delivery, charge pump circuits, and power amplifiers).

Plasmonic nanoparticles (NPs) represent an outstanding class of nanomaterials that have the capability to localize light at the nanoscale by exploiting a phenomenon called "localized plasmon resonance." This book reviews recent efforts devoted to the utilization of NPs in many research fields, such as photonics, optics, and plasmonics. In this framework, a particular interest is devoted to "active plasmonics," a quite broad concept that indicates those applications in which NPs play an "active" role, such as the realization of gain-assisted means, utilization of NPs embedded in liquid crystalline and flexible materials, and exploitation of renewable solar energy. The book puts together contributions from outstanding international research groups in the field of plasmonic nanomaterials.

This book seeks to address the fundamental understanding of the structure and chemistry of sustainable polymers. It covers the fundamentals of sustainable polymers and presents guidelines in a logical and clear manner for students and researchers. The text explores the structure and chemistry of various sustainable polymers, such as cellulose, hemicellulose, lignin, chitosan, starch, guar gum, pectin, and protein, for possible development of green sustainable materials. Each chapter is authored by highly accomplished experts in the field of sustainable polymers and discusses in detail the chemistry and structure of sustainable polymers procured from different natural resources.

This book is the first text to provide a comprehensive assessment of the application of fundamental principles of dissolution and drug release testing to poorly soluble compounds and formulations. Such drug products are, vis-à-vis their physical and/or chemical properties, inherently incompatible with aqueous dissolution. However, dissolution methods are required for product development and selection, as well as to fulfill regulatory obligations with respect to biopharmaceutical assessment and product quality understanding.

The realization of the application potential of topological insulators requires a comprehensive and deep understanding of transport processes in these novel materials. This book explores the origin of the protected Dirac-like states in topological insulators and gives insight into some of their representative transport properties. These include the quantum spin¿Hall effect, nonlocal edge transport, backscattering of helical edge and surface states, weak antilocalization, unconventional triplet p-wave superconductivity, topological bound states, and emergent Majorana fermions in Josephson junctions, as well as superconducting Klein tunneling.

This book describes the innovation in technologies through the development of functionalized ceramic materials for energy, environment, and health care applications. It describes the recent and expected challenges along with potential solutions for advanced techniques for the synthesis and characterization of nanostructure ceramics and their composites. The book will benefit researchers, scientists, engineers, and technologists interested in traditional and advanced smart ceramic composites and students of smart ceramics, nanomaterials, nanoscience, and engineering.

This book introduces and discusses the basic principles of pulsed laser¿matter interaction, with a focus on its peculiarities and perspectives compared to other conventional techniques and state-of-the-art applications. The book starts with an overview of the growth topics, followed by a discussion of laser¿matter interaction depending on laser pulse duration, background conditions, materials, and combination of materials and structures. The information outlines the foundation to introduce examples of laser nanostructuring/processing of materials, pointing out the importance of pulsed laser¿based technologies in modern (nano)science.

Graphene is expected to play an important role in future nanoelectronic applications, but the only way to achieve this goal is to grow graphene directly on a semiconductor, integrating it in the chain for the production of electronic circuits and devices. This book summarizes the latest achievements in this field, with particular attention to the graphitization of SiC. Through high-temperature annealing in a controlled environment, it is possible to decompose the topmost SiC layers, obtaining quasi-ideal graphene by Si sublimation with record electronic mobilities, while selective growth on patterned structures makes possible the opening of a gap by quantum confinement.

This is the first book dedicated exclusively to epitaxial graphene on silicon carbide (EG-SiC). It addresses comprehensively all aspects relevant for the study and technology development of EG materials and their applications. It includes the state of the art on the synthesis of EG-SiC, which is profusely explained as a function of SiC substrate characteristics, such as polytype, polarity, and wafer cut, as well as both in situ and ex situ conditioning techniques, including H2 pre-deposition annealing, chemical mechanical polishing, etc.
