This companion volume to "Fundamental Polymer Science" (Gedde and
Hedenqvist, 2019) offers detailed insights from leading
practitioners into experimental methods, simulation and modelling,
mechanical and transport properties, processing, and sustainability
issues. Separate chapters are devoted to thermal analysis,
microscopy, spectroscopy, scattering methods, and chromatography.
Special problems and pitfalls related to the study of polymers are
addressed. Careful editing for consistency and cross-referencing
among the chapters, high-quality graphics, worked-out examples, and
numerous references to the specialist literature make "Applied
Polymer Science" an essential reference for advanced students and
practicing chemists, physicists, and engineers who want to solve
problems with the use of polymeric materials.
The first book to chronicle how innovation in laboratory designs
for botanical research energized the emergence of physiological
plant ecology as a vibrant subdiscipline  Laboratory
innovation since the mid-twentieth century has powered advances in
the study of plant adaptation, evolution, and ecosystem function.
The phytotron, an integrated complex of controlled-environment
greenhouse and laboratory spaces, invented by Frits W. Went in the
1950s, set off a worldwide laboratory movement and transformed the
plant sciences. Sharon Kingsland explores this revolution through a
comparative study of work in the United States, France, Australia,
Israel, the USSR, and Hungary. Â These advances in botanical
research energized physiological plant ecology. Case studies
explore the development of phytotron spinoffs such as mobile
laboratories, rhizotrons, and ecotrons. Scientific problems include
the significance of plant emissions of volatile organic compounds,
symbiosis between plants and soil fungi, and the discovery of new
pathways for photosynthesis as an adaptation to hot, dry climates.
The advancement of knowledge through synthesis is a running theme:
linking disciplines, combining laboratory and field research, and
moving across ecological scales from leaf to ecosystem. The book
also charts the history of modern scientific responses to the
emerging crisis of food insecurity in the era of global warming.
For some people with disabilities, their interest and skills are
best applied to laboratory work. Science laboratories are
environments where hazardous materials and processes are in use,
and assessments are required to mitigate risk and ensure compliance
with Occupational Safety and Health Administration (OSHA) and
Environmental Protection Agency (EPA) regulations. Accommodating
individuals in a laboratory requires balancing adherence to those
regulations, as well as the Americans with Disabilities Act (ADA)
technical access standards. Individualized assessment and
accommodation are needed to ensure that a qualified individual with
a disability can work or study effectively in the laboratory while
ensuring a safe working environment for all. This book is intended
to be a helpful guide for professionals to understand how to
provide equal access to people with disabilities in a laboratory
environment. It will review the breadth of protections that are
provided by the ADA. This book also covers the roles and
responsibilities of persons involved in laboratory oversight,
including institutional policies and their limitations with respect
to providing appropriate support for individualized assessments in
the laboratory.
The Nobel Prize of 1986 on Sc- ning Tunneling Microscopy sig- led a
new era in imaging. The sc- ning probes emerged as a new i- trument
for imaging with a pre- sion suf?cient to delineate single atoms.
At ?rst there were two - the Scanning Tunneling Microscope, or STM,
and the Atomic Force Mic- scope, or AFM. The STM relies on
electrons tunneling between tip and sample whereas the AFM depends
on the force acting on the tip when it was placed near the sample.
These were quickly followed by the - gneticForceMicroscope,MFM,and
the Electrostatic Force Microscope, EFM. The MFM will image a
single magnetic bit with features as small as 10nm. With the EFM
one can monitor the charge of a single electron. Prof. Paul Hansma
at Santa Barbara opened the door even wider when he was able to
image biological objects in aqueous environments. At this point the
sluice gates were opened and a multitude of different instruments
appeared. There are signi?cant differences between the Scanning
Probe Microscopes or SPM, and others such as the Scanning Electron
Microscope or SEM. The probe microscopes do not require preparation
of the sample and they operate in ambient atmosphere, whereas, the
SEM must operate in a vacuum environment and the sample must be
cross-sectioned to expose the proper surface. However, the SEM can
record 3D image and movies, features that are not available with
the scanning probes.
Scientific techniques developed in materials science offer
invaluable information to archaeology, art history, and
conservation. A rapidly growing number of innovative methods, as
well as many established techniques, are constantly being improved
and optimized for the analysis of cultural heritage materials. The
result is that on the one hand more complex problems and questions
can be confronted, but on the other hand the required level of
technical competence is widening the existing cultural gap between
scientists and end users, such as archaeologists, museum curators,
art historians, and many managers of cultural heritage who have a
purely humanistic background.
The book is intended as an entry-level introduction to the methods
and rationales of scientific investigation of cultural heritage
materials, with emphasis placed on the analytical strategies, modes
of operation, and resulting information rather than on
technicalities. The extensive and updated reference list should be
a useful starting point for further reading. Students and
researchers from the humanities approaching scientific
investigations should find it useful, as well as scientists
applying familiar techniques and methods to unfamiliar problems
related to cultural heritage.

Acoustic microscopy enables the elastic properties of materials to
be imaged and measured with the resolution of a good microscope. By
using frequencies in the microwave regime, it is possible to make
the acoustic wavelength comparable with the wavelength of light,
and hence to achieve a resolution comparable with an optical
microscope. Solids can support both longitudinal and transverse
acoustic waves. At surfaces a unique combination of the two known
as Raleigh waves can propagate, and in many circumstances these
dominate the contrast in acoustic microscopy. Following the
invention of scanning probe microscopes, it is now possible to use
an atomic force microscope to detect the acoustic vibration of a
surface with resolution in the nanometre range, thus beating the
diffraction limit by operating in the extreme near-field. This
second edition of Acoustic Microscopy has a major new chapter on
the technique and applications of acoustically excited probe
microscopy.
Most cells will survive removal from the natural mic- environment
of their in vivo tissue and placement into a sterile culture dish
under optimal conditions. Not only do they survive, but they also
multiply and express differen- ated properties in such a culture
dish. A few cells do this in suspension, but most will need some
kind of mechanical support substituting for their natural
connections with other cells. The surface of a culture dish that
might have to be coated is usually sufficient. The recent trend to
standa- ization of conditions and the existence of commercial ent-
prises with adequate funds and specializing in the needs of
scientists were responsible for the tremendous proliferation of
cell culture techniques in all fields of research in the last 20
years. No longer does a scientist have to concentrate all his/her
efforts on that technology; the new trends make it feasible to
employ cell culture techniques as only one of the many methods
available in a small corner of a larger research laboratory. Some
areas of research depend more heavily than others on cell culture
techniques. Neuroscience is one of the areas that has developed
hand in hand with the prol- eration of cell culture methodology.
Molecular biological aspects, cell differentiation and development,
neurophy- ological and neurochemical studies, as well as
investigations into the nature of various diseases are now to a
large extent dependent on the use of cell cultures.
Mammalian cells have evolved a complex multicomponent machinery
that enables them to sense and respond to a wide variety of
potentially toxic agents present in their environment. These stress
responses are often associated with an increased cellular capacity
to tolerate normally lethal levels of an insult. The realization
that the mammalian stress response may be intimately linked with
many human diseases, including rheumatoid arthritis, ischemia,
fever, infection, and cancer, has led to an explosion of interest
in this research area. Stress Response: Methods and Protocols
brings together a diverse array of practical methodologies that may
be employed to address various aspects of the response of mammalian
cells to environmental stress. The p- tocols are carefully
described by authors who have both devised and succe- fully
employed them, and they represent a mixture not only of
well-established techniques, but also new technologies at the
leading edge of research. The areas covered include the detection
and assay of stress-induced damage, the acti- tion of signal
transduction pathways, stress-inducible gene expression, and stress
protein function. Although no volume of this size can be
comprehensive and the topics covered reflect a personal choice, it
is hoped that it will prove of subst- tial interest and use to a
wide range of research workers in the field.
This book discusses fundamentally new biomedical imaging methods,
such as holography, holographic and resonant interferometry, and
speckle optics. It focuses on the development of holographic
interference microscopy and its use in the study of phase objects
such as nerve and muscle fibers subjected to the influence of laser
radiation, magnetic fields, and hyperbaric conditions. The book
shows how the myelin sheath and even the axon itself exhibit
waveguide properties, enabling a fresh new look at the mechanisms
of information transmission in the human body. The book presents
theoretically and experimentally tested holographic and
speckle-optical methods and devices used for investigating complex,
diffusely scattering surfaces such as skin and muscle tissue.
Additionally, it gives broad discussion of the authors' own
original fundamental and applied research dedicated to helping
physicians introduce new contact-less methods of diagnosis and
treatment of diseases of the cardiovascular and neuromuscular
systems into medical practice. The book is aimed at a broad
spectrum of scientific specialists in the fields of speckle optics,
holography, laser physics, morphology and cytochemistry, as well as
medical professionals such as physiologists, neuropathologists,
neurosurgeons, cardiologists and dentists.
Microcharacterization of materials is a rapidly advancing field.
Among the many electron and ion probe techniques, the
cathodoluminescence mode of an electron probe instrument has
reached a certain maturity, which is reflected by an increas ing
number of publications in this field. The rapid rate of progress in
applications of cathodoluminescence techniques in characterizing
inorganic solids has been especially noticeable in recent years.
The main purpose of the book is to outline the applications of cath
odoluminescence techniques in the assessment of optical and
electronic proper ties of inorganic solids, such as semiconductors,
phosphors, ceramics, and min erals. The assessment provides, for
example, information on impurity levels derived from
cathodoluminescence spectroscopy, analysis of dopant concentra
tions at a level that, in some cases, is several orders of
magnitude lower than that attainable by x-ray microanalysis, the
mapping of defects, and the determination of carrier lifetimes and
the charge carrier capture cross sections of impurities. In order
to make the book self-contained, some basic concepts of solid-state
phys ics, as well as various cathodoluminescence techniques and the
processes leading to luminescence phenomena in inorganic solids,
are also described. We hope that this book will be useful to both
scientists and graduate students interested in
microcharacterization of inorganic solids. This book, however, was
not intended as a definitive account of cathodoluminescence
analysis of in organic solids. In considering the results presented
here, readers should re member that many materials have properties
that vary widely as a function of preparation conditions."
A superb collection of time-tested, key techniques for
investigating nervous system function, as well as the actions of
drugs on the nervous system. The methods range from authoritative
treatment of such well-established techniques as recording
electrical activity in the brain, to practical coverage of
state-of-the-art methods, including neural transplantation and
antisense technology. The techniques described are particularly
suitable for studying the mechanisms of action of psychotropic
drugs and drugs of abuse, as well as the etiology and
pharmacotherapy of neuropsychiatric diseases and neurodegenerative
disorders. Several of the methods detailed are highly useful in
screening potential drugs for the treatment of depression, anxiety
disorders, schizophrenia, and Parkinson's and Alzheimer's disease.
Algae are simple, primitive, heterogeneous, autotrophic, eukaryotic
or prokaryotic organisms that lead a symbiotic, parasitic or
free-living mode of life. Microalgae and macroalgae possess great
potential in various fields of application. Microalgae are
ubiquitous and extremely diverse microorganisms that can accumulate
toxic contaminants and heavy metals from wastewater, making them a
superior candidate to become a powerful nanofactory. Algae were
discovered to reduce the presence of metal ions, and afterwards aid
in the biosynthesis of nanoparticles. Since algae-mediated biogenic
nanoparticles are eco-friendly, cost-effective, high-yielding,
speedy and energy-efficient, a large number of studies have been
published on them in the last few years. This book focuses on
recent progress on the utilization of algae for the synthesis of
nanoparticles, their characterization and the possible mechanisms
involved. Bioprospecting Algae for Nanosized Materials describes
the synthesis of algal nanomaterials and its application in various
fields for sustainable development. This book outlines the
procedures to prepare phyconanomaterials, techniques to utilize the
nanomaterials, and applications in agriculture, environment and
medicine.
Micro-Raman Spectroscopy introduces readers to the theory and
