This book provides an introduction to topological matter with a
focus on insulating bulk systems. A number of prerequisite concepts
and tools are first laid out, including the notion of symmetry
transformations, the band theory of semiconductors and aspects of
electronic transport. The main part of the book discusses realistic
models for both time-reversal-preserving and -violating topological
insulators, as well as their characteristic responses to external
perturbations. Special emphasis is given to the study of the
anomalous electric, thermal, and thermoelectric transport
properties, the theory of orbital magnetisation, and the polar Kerr
effect. The topological models studied throughout this book become
unified and generalised by means of the tenfold
topological-classification framework and the respective systematic
construction of topological invariants. This approach is further
extended to topological superconductors and topological semimetals.
This book covers a wide range of topics and aims at the transparent
presentation of the technical aspects involved. For this purpose,
homework problems are also provided in dedicated Hands-on sections.
Given its structure and the required background level of the
reader, this book is particularly recommended for graduate students
or researchers who are new to the field.
Luftschall uberstreicht nicht nur den Bereich menschlicher
Sprachkommunikation, sondern belegt als Infraschall und Ultraschall
Bereiche, die auch intensiv technisch oder medizinisch genutzt
werden. Diese Nutzung setzt die Kenntnis seiner Eigenschaften
voraus, die mit dem zeitlichen und raumlichenVerlauf der
Druckanderungen im Schallfeld beschrieben werden koennen. Fur die
Wandlung der Schallparameter in registrierbare Werte stehen
verschiedene Moeglichkeiten zur Verfugung. Die Umsetzung in
elektrische Spannungen mit Mikrofonen steht dabei weit an der
Spitze. Je nach erforderlicher Genauigkeit werden hierbei
Konstruktionen auf unterschiedlicher Basis verwendet. Dieser Band
befasst sich mit den Eigenschaften und Moeglichkeiten der
verschiedenen Loesungen, den damit verbundenen Grenzen der
Schallgroessenerfassung sowie einem Ausblick auf zukunftige
Entwicklungen.
Hyperbolic metamaterials were originally introduced to overcome the
diffraction limit of optical imaging. Soon thereafter it was
realized that hyperbolic metamaterials demonstrate a number of
novel phenomena resulting from the broadband singular behavior of
their density of photonic states. These novel phenomena and
applications include super resolution imaging, new stealth
technologies, enhanced quantum-electrodynamic effects, thermal
hyperconductivity, superconductivity, and interesting gravitation
theory analogs. Here I review typical material systems, which
exhibit hyperbolic behavior and outline important new applications
of hyperbolic metamaterials, such as imaging experiments with
plasmonic hyperbolic metamaterials and novel VCSEL geometries, in
which the Bragg mirrors may be engineered in such a way that they
exhibit hyperbolic properties in the long wavelength infrared
range, so that they may be used to efficiently remove excess heat
from the laser cavity. I will also discuss potential applications
of self-assembled photonic hypercrystals. This system bypasses 3D
nanofabrication issues, which typically limit hyperbolic
metamaterial applications. Photonic hypercrystals combine the most
interesting features of hyperbolic metamaterials and photonic
crystals.
Measurement and Instrumentation: Theory and Application, Second
Edition, introduces undergraduate engineering students to
measurement principles and the range of sensors and instruments
used for measuring physical variables. This updated edition
provides new coverage of the latest developments in measurement
technologies, including smart sensors, intelligent instruments,
microsensors, digital recorders, displays, and interfaces, also
featuring chapters on data acquisition and signal processing with
LabVIEW from Dr. Reza Langari. Written clearly and comprehensively,
this text provides students and recently graduated engineers with
the knowledge and tools to design and build measurement systems for
virtually any engineering application.
Photoemission (also known as photoelectron) spectroscopy refers to
the process in which an electron is removed from a specimen after
the atomic absorption of a photon. The first evidence of this
phenomenon dates back to 1887 but it was not until 1905 that
Einstein offered an explanation of this effect, which is now
referred to as ""the photoelectric effect"".Quantitative Core Level
Photoelectron Spectroscopy: A Primer tackles the pragmatic aspects
of the photoemission process with the aim of introducing the reader
to the concepts and instrumentation that emerge from an
experimental approach. The basic elements implemented for the
technique are discussed and the geometry of the instrumentation is
explained. The book covers each of the features that have been
observed in the X-ray photoemission spectra and provides the tools
necessary for their understanding and correct identification.
Charging effects are covered in the penultimate chapter with the
final chapter bringing closure to the basic uses of the X-ray
photoemission process, as well as guiding the reader through some
of the most popular applications used in current research.
The concept of smart drug delivery vehicles involves designing and
preparing a nanostructure (or microstructure) that can be loaded
with a cargo. This can be a therapeutic drug, a contrast agent for
imaging, or a nucleic acid for gene therapy. The nanocarrier serves
to protect the cargo from degradation by enzymes in the body, to
enhance the solubility of insoluble drugs, to extend the
circulation half-life, and to enhance its penetration and
accumulation at the target site. Importantly, smart nanocarriers
can be designed to be responsive to a specific stimulus, so that
the cargo is only released or activated when desired. In this
volume we cover smart nanocarriers that respond to internal stimuli
that are intrinsic to the target site. These stimuli are specific
to the cell type, tissue or organ type, or to the disease state
(cancer, infection, inflammation etc). pH-responsive nanostructures
can be used for cargo release in acidic endosomal compartments, in
the lower pH of tumors, and for specific oral delivery either to
the stomach or intestine. Nanocarriers can be designed to be
substrates of a wide-range of enzymes that are over-expressed at
disease sites. Oxidation and reduction reactions can be taken
advantage of in smart nanocarriers by judicious molecular design.
Likewise, nanocarriers can be designed to respond to a range of
specific biomolecules that may occur at the target site. In this
volume we also cover dual and multi-responsive systems that combine
stimuli that could be either internal or external.
This book describes modern focused ion beam microscopes and
techniques and how they can be used to aid materials metrology and
as tools for the fabrication of devices that in turn are used in
many other aspects of fundamental metrology. Beginning with a
description of the currently available instruments including the
new addition to the field of plasma-based sources, it then gives an
overview of ion solid interactions and how the different types of
instrument can be applied. Chapters then describe how these
machines can be applied to the field of materials science and
device fabrication giving examples of recent and current activity
in both these areas.

volume we cover smart nanocarriers that respond to externally
applied stimuli that usually involve application of physical
energy. This physical energy can be applied from outside the body
and can either cause cargo release, or can activate the
nanostructure to be cytotoxic, or both. The stimuli covered include
light of various wavelengths (ultraviolet, visible or infrared),
temperature (increased or decreased), magnetic fields (used to
externally manipulate nanostructures and to activate them),
ultrasound, and electrical and mechanical forces. Finally we
discuss the issue of nanotoxicology and the future scope of the
field.
This book highlights the application of Time-of-Flight Secondary
Ion Mass Spectrometry (ToF-SIMS) for high-resolution surface
analysis and characterization of materials. While providing a brief
overview of the principles of SIMS, it also provides examples of
how dual-beam ToF-SIMS is used to investigate a range of materials
systems and properties. Over the years, SIMS instrumentation has
dramatically changed since the earliest secondary ion mass
spectrometers were first developed. Instruments were once dedicated
to either the depth profiling of materials using high-ion-beam
currents to analyse near surface to bulk regions of materials
(dynamic SIMS), or time-of-flight instruments that produced complex
mass spectra of the very outer-most surface of samples, using very
low-beam currents (static SIMS). Now, with the development of
dual-beam instruments these two very distinct fields now overlap.
In the last few years, several "bottom-up" and "top-down" synthesis
routes have been developed to produce tailored hybrid nanoparticles
(HNPs). This book provides a new insight into one of the most
promising "bottom-up" techniques, based on a practical
magnetron-sputtering inert-gas-condensation method. A modified
magnetron-sputtering-based inert-gas-condensation (MS-IGC) system
is presented, and its performances under different conditions are
evaluated. Designed for graduate students, researchers in physics,
materials science, biophysics and related fields, and process
engineers, this new resource fills a critical need to understand
the fundamentals behind the design and tailoring of the
nanoparticles produced by the MS-IGC method. It shows that the
morphology, the size and the properties of the nanoparticles can be
modulated by tuning the deposition parameters such as the energy,
the cooling rate, and the collision and coalescence processes
experienced by the nanoparticles during their formation. The
mechanisms of formation of different HNPs are suggested, combining
the physico-chemical properties of the materials with the
experimental conditions. This book illustrates the potential of
MS-IGC method to synthesize multifunctional nanoparticles and
nanocomposites with accurate control on their morphology and
structure. However, for a better understanding of HNPs formation,
further improvements in characterization methods of aggregation
zone conditions are needed. In addition, the optimization of the
yield and harvesting process of HNPs is essential to make this
method sufficiently attractive for large-scale production.
In machine tools, the designed systems include many components,
such as sensors, actuators, joints and motors. It is required that
all these components work properly to ensure safety. This book
examines fault monitoring and control schemes in machine systems,
as well as detecting machines whenever a failure occurs and
accommodating the failures as soon as possible. Also discussed are
centre-less grinding machines; improving machine tool performance
through structural and process dynamics modelling and exploring the
strength of the Japanese machine tool industry.
Experimental Methods for Engineers, 8/e, offers the broadest range
of experimental measurement techniques available for mechanical and
general engineering applications. Offering clear descriptions of
the general behavior of different measurement techniques, such as
pressure, flow, and temperature, the text emphasizes the use of
uncertainty analysis and statistical data analysis in estimating
the accuracy of measurements. Maintaining its thorough coverage of
thermal-fluid measurement techniques, the text continues to
emphasize experimental uncertainties as essential elements in
experiment design, execution, and instrument selection.
The inclusion of an electrical measurement course in the
undergraduate curriculum of electrical engineering is important in
forming the technical and scientific knowledge of future electrical
engineers. This book explains the basic measurement techniques,
instruments, and methods used in everyday practice. It covers in
detail both analogue and digital instruments, measurements errors
and uncertainty, instrument transformers, bridges, amplifiers,
oscilloscopes, data acquisition, sensors, instrument controls and
measurement systems. The reader will learn how to apply the most
appropriate measurement method and instrument for a particular
application, and how to assemble the measurement system from
physical quantity to the digital data in a computer. The book is
primarily intended to cover all necessary topics of instrumentation
and measurement for students of electrical engineering, but can
also serve as a reference for engineers and practitioners to expand
or refresh their knowledge in this field.

chemical, oil/gas, pharmaceutical, pollution, energy, plastics,
paper, wastewater, food, etc. industries.
Measures are the subject of this unusual book, in which Robert
Tavernor offers a fascinating account of the various measuring
systems human beings have devised over two millennia. Tavernor
urges us to look beyond the notion that measuring is strictly a
scientific activity, divorced from human concerns. Instead, he sets
measures and measuring in cultural context and shows how deeply
they are connected to human experience and history.
The book explores changing attitudes toward measure, focusing on
key moments in art, sculpture, architecture, philosophy, and the
development of scientific thought. It encompasses the journey of
Western civilization from the construction of the Great Pyramid to
the first manned flight to the moon. Beginning with a review of
early measuring standards that referred to the feet and inches of
ideal bodies, the book then tracks how Enlightenment interest in a
truly scientific system of measure led to the creation of the
metric system. This "rational" approach to measure in turn has
inspired artists, architects, writers, and others to seek a balance
that takes the human story into account. Tavernor concludes with a
discussion of measure in our own time, when space travel presents
to humankind a direct encounter with the unfathomable measure of
the universe.
Fur akustische Planungen ist es unerlasslich zu wissen, wie viel
Schall eine Quelle abstrahlt. Auch die Wahl einer gerauscharmen
Maschine ist nur moeglich, wenn die jeweiligen Herstellerangaben
miteinander vergleichbar sind. Die Schallleistung ist in beiden
Fallen die passende Groesse, da sie die Schallabstrahlung einer
Quelle unabhangig vom umgebenden Raum beschreibt. Gerade diese
Ortsunabhangigkeit ist aber erforderlich, um mehrere Quellen
zuverlassig vergleichen zu koennen oder um z.B. die an einem
Arbeitsplatz in einer Werkhalle oder an einem Immissionsort in der
Nachbarschaft zu erwartenden Gerauschimmissionen prognostizieren zu
koennen. In dem Band "Schallleistung" werden die theoretischen
Grundlagen erlautert und verschiedene, grundlegende Messmethoden
vorgestellt. Damit wird die Leserin oder der Leser in die Lage
versetzt, das fur eine spezifische Messaufgabe passende
Messverfahren auszuwahlen und, falls in den einschlagigen
Regelwerken keine Vorgaben fur besondere Einzelfalle zu finden
sind, angepasste Loesungen zu erarbeiten, die mit den jeweiligen
Messprinzipien in Einklang stehen.
Biosensors are becoming increasingly important bioanalytical tools
in the pharmaceutical, biotechnology, food, and other consumer
oriented industries. The technology, though well developed in
Europe, is slowly developing and has begun to generate interest in
the United States only over the past couple of years. Research is
now being directed toward the development of biosensors that are
versatile, economical, and simple to use.
Engineering Biosensors is a comprehensive introduction to
biosensors that includes numerous illustrations to further explain
the main concepts and practical examples from existing literature.
It describes what biosensors are, where they are used, and how
their performance is affected by existing surface characteristics.
A better understanding of biosensors, as provided by this book,
will greatly assist in the design of new as well as the improvement
of existing biosensors. Readers are also provided with invaluable
and hard-to-find data on the economics of the biosensor market to
assist them in better understanding the market and where it is
heading.
