Cryogenics is the study of low temperature interactions -
temperatures well below those existing in the natural universe.
- Experiments described in technical detail
The role of the Maillard reaction in forming flavors from amino
acid and sugar precursors has been studied for many years. To
establish the basic chemistry of the reaction, researchers have
used model systems, often solutions of a single amino acid with a
single sugar. Despite the apparent simplicity of the system,
heating such a solution can generate tens if not hundreds of
compounds, which requires careful and time-consuming analysis to
identify and quantify each component.
In this second edition, Edwin Frankel has updated and extended his
now well-known book Lipid oxidation which has come to be regarded
as the standard work on the subject since the publication of the
first edition seven years previously. His main objective is to
develop the background necessary for a better understanding of what
factors should be considered, and what methods and lipid systems
should be employed, to achieve suitable evaluation and control of
lipid oxidation in complex foods and biological systems.
People are immersed in electromagnetic fields from such sources as
power lines, domestic appliances, mobile phones, and even
electrical storms. All living beings sense electric fields, but the
physical origins of the phenomenon are still unclear.
Magnetobiology considers the effects of electromagnetic fields on
living organisms. It provides a comprehensive review of relevant
experimental data and theoretical concepts, and discusses all major
modern hypotheses on the physical nature of magnetobiological
effects. It also highlights some problems that have yet to be
solved and points out new avenues for research.
Chemical Thermodynamics: Principles and Applications presents a
thorough development of the principles of thermodynamics--an
old
In this volume, inorganic, organic, and bioorganic chemistry are
represented in contributions from around the world. Pioneering work
in self-assembled structures organized by the use of transition
metals is described in chapter 1, followed by details of extensive
studies of self-assembled structures formed from various
biomolecules in chapter 2. The next two chapters describe the
formation of spherical molecular containers and their understanding
of such structures based on Platonic and Archimedean solids, and
the fascinating family of synthetic peptide receptors and the
interactions that can be explored using these host molecules. In
chapter 5 a mixture of computational chemistry, drug design, and
synthetic organic and inorganic chemistry in the development of
superoxide dismutase mimics is described. The final two chapters
discuss the bioorganic and supramolecular principles required for
the design of synthetic artificial enzymes, and the supramolecular
self-assembly and its possible role in the origin of life.
This is the fifth volume of "Advances in Sonochemistry" the first
having been published in 1990. The definition of sonochemistry has
developed to include not only the ways in which ultrsound has been
harnessed to effect chemistry but also its uses in material
processing. Subjects included range from chemical dosimetry to
ultrasound in microbiology to ultrasound in the extraction of plant
materials and in leather technology.
The progress in device technologies are surveyed in this volume. Included are Si/ (Si-Ge) heterojunctions for high-speed integrated circuits. Schottky-barrier arrays in Si and Si-Ge alloys for infrared imaging, III-V quantum-well detector structures operated in the heterodyne mode for high-data-rate communications, and III-V heterostructures and quantum-wells for infrared transmissions.
Based on the successful first edition, this book gives a general
theoretical introduction to electrochemical power cells (excluding
fuel cells) followed by a comprehensive treatment of the principle
battery types - covering chemistry, fabrication characteristics and
applications. There have been many changes in the field over the
last decade and many new systems have been commercialised. Since
the recent advent of battery powered consumer products (mobile
phones, camcorders, lap-tops etc.) advanced power sources have
become far more important. This text provides an up-to-date account
of batteries which is accessible to anyone with a basic knowledge
of chemistry and physics.
Part of a series which presents reports of efforts in all areas of supramolecular science, this volume discusses a variety of topics in the field.
This text provides a uniform and consistent approach to diversified
problems encountered in the study of dynamical processes in
condensed phase molecular systems. Given the broad
interdisciplinary aspect of this subject, the book focuses on three
themes: coverage of needed background material, in-depth
introduction of methodologies, and analysis of several key
applications. The uniform approach and common language used in all
discussions help to develop general understanding and insight on
condensed phases chemical dynamics. The applications discussed are
among the most fundamental processes that underlie physical,
chemical and biological phenomena in complex systems.
Concentrating on techniques for the detection and measurement of radioactivity, this book offers a guide to selecting the type of counter, type of source sample, duration for which the counting must be made, and the radiation emitted by the isotope for its efficient detection. It introduces a novel concept to explain not only the decay processes but also the selection of counting procedures for detecting and measuring radioactivity. The author builds up the foundation from the nature of the interaction of radiation with matter. He also highlights the differences between an ordinary chemical laboratory and a radiochemical one.
Thermodynamic property data are important in many engineering applications in the chemical processing and petroleum refining industries. The "Handbook of Thermodynamic Diagrams" series presents volume and enthalpy diagrams (graphs) for the major organic chemicals and hydrocarbons, as well as the major inorganic compounds and elements. The graphs, arranged by carbon number and chemical formula, cover a wide range of pressures and temperatures to enable engineers to determine quickly values at various points. This volume covers inorganic compounds and elements.
This series provides engineers with vapor pressure data for process design, production, and environmental applications.
This book focuses on broadly defined areas of chemical information science- with special emphasis on chemical informatics- and computer-aided molecular design. The computational and cheminformatics methods discussed, and their application to drug discovery, are essential for sustaining a viable drug development pipeline. It is increasingly challenging to identify new chemical entities and the amount of money and time invested in research to develop a new drug has greatly increased over the past 50 years. The average time to take a drug from clinical testing to approval is currently 7.2 years. Therefore, the need to develop predictive computational techniques to drive research more efficiently to identify compounds and molecules, which have the greatest likelihood of being developed into successful drugs for a target, is of great significance. New methods such as high throughput screening (HTS) and techniques for the computational analysis of hits have contributed to improvements in drug discovery efficiency. The SARMs developed by Jurgen and colleagues have enabled display of SAR data in a more transparent scaffold/functional SAR table. There are many tools and databases available for use in applied drug discovery techniques based on polypharmacology. The cheminformatics approaches and methodologies presented in this volume and at the Skolnik Award Symposium will pave the way for improved efficiency in drug discovery. The lectures and the chapters also reflect the various aspects of scientific enquiry and research interests of the 2015 Herman Skolnik award recipient.
This book presents the SPH method (Smoothed-Particle Hydrodynamics)
for fluid modelling from a theoretical and applied viewpoint. It
comprises two parts that refer to each other. The first one,
dealing with the fundamentals of Hydraulics, is based on the
elementary principles of Lagrangian and Hamiltonian Mechanics. The
specific laws governing a system of macroscopic particles are
built, before large systems involving dissipative processes are
explained. The continua are discussed, and a fairly exhaustive
account of turbulence is given. The second part discloses the bases
of the SPH Lagrangian numerical method from the continuous
equations, as well as from discrete variational principles, setting
out the method's specific properties of conservativity and
invariance. Various numerical schemes are compared, permanently
referring to the physics as dealt with in the first part.
Applications to schematic instances are discussed, and, ultimately,
practical applications to the dimensioning of coastal and fluvial
structures are considered.
Low-Energy Nuclear Reactions and New Energy is a summary of
selected experimental and theoretical research performed over the
last 19 years that gives profound and unambiguous evidence for low
energy nuclear reaction (LENR), historically known as cold fusion.
Chemometrics and Chemoinformatics gives chemists and other scientists an introduction to the field of chemometrics and chemoinformatics. Chemometrics is an approach to analytical chemistry based on the idea of indirect observation. Measurements related to the chemical composition of a substance are taken, and the value of a property of interest is inferred from them through some mathematical relation. Basically, chemometrics is a process. Measurements are made, data is collected, and information is obtained to periodically assess and acquire knowledge. This, in turn, has led to a new approach for solving scientific problems: (1) measure a phenomenon or process using chemical instrumentation that generates data inexpensively, (2) analyze the multivariate data, (3) iterate if necessary, (4) create and test the model, and (5) develop fundamental multivariate understanding of the process. Chemoinformatics is a subfield of chemometrics, which encompasses the analysis, visualization, and use of chemical structural information as a surrogate variable for other data or information. The boundaries of chemoinformatics have not yet been defined. Only recently has this term been coined. Chemoinformatics takes advantage of techniques from many disciplines such as molecular modeling, chemical information, and computational chemistry. The reason for the interest in chemoinformatics is the development of experimental techniques such as combinatorial chemistry and high-throughput screening, which require a chemist to analyze unprecedented volumes of data. Access to appropriate algorithms is crucial if such experimental techniques are to be effectively exploited for discovery. Many chemists want to use chemoinformatic methods in their work but lack the knowledge required to decide which techniques are the most appropriate.
Following Ionic Liquids: Industrial Applications to Green Chemistry, SS #818, by the same editors, this book focuses on exciting new developments in ionic liquids.
Developing innovative efficient and sensitive spectroscopic and optical techniques for studying biomedically relevant molecules, structures and processes in vitro and in vivo is a field of rapidly growing interest. This symposium book covers novel and exciting approaches in biomedical spectroscopy. Several chapters deal with infrared and Raman spectroscopy. These complimentary vibrational spectroscopic techniques are capable of monitoring molecular structures as well as structural changes. Such studies are of interest for understanding diseases at a molecular level as well as for developing techniques for efficient early diagnosis based on molecular structural information. The chapters demonstrate also applications vibrational spectroscopy in proteomics and the characterization of micro organisms. The second section of the book introduces surface enhanced Raman scattering (SERS), demonstrates the application of the effect in the biomedical field and develops the concept of multifunctional nanosensors. The measurement of intrinsic optical signals from biological objects such as nerve tissue are discussed in the next section of the book. Chapters deal also with Coherent anti-Stokes Raman scattering (CARS) and fluorescence fluctuation spectroscopy. Other chapters illustrate how photons of very different energies, in the Terahertz and in the ultra violet range, can be used to retrieve molecular structural information from native biomolecules. The electrical properties of protein molecules adsorbed onto a gold substrate are studied by using a scanning Kelvin nanoprobe in a microarray format. The final chapters in the book demonstrate the powerful combination of different spectroscopic techniques for the characterization of biomolecules as well as native and engineered biomaterials. These chapters combine information from Raman and Inelastic Neutron Scattering, optical absorbance and energy dispersive X-ray analysis, positron annihilation lifetime spectroscopy (PALS), 1H NMR, and 129Xe NMR X-ray diffraction and fluorescence resonance energy transfer.
The interactions of microbes with surfaces are important to many
natural and engineered processes, affecting a wide range of
applications from decontamination of surfaces or drinking water,
prevention of microbial colonization of biomaterials, and bacterial
processes in the environment. Therefore, there is great interest in
understanding the fundamental behavior of microbes at surfaces.
Topics are included that address interactions of cells with a
number of surfaces for antifouling and microbial cell-based sensor
applications; mechanistic studies of antimicrobial peptides and
quorum sensing; exploration of experimental and theoretical models
of a cell surface; cell surface display of peptides and enzymes as
biofabrication techniques; the fate and transport of bacteria in
the natural environment, as well as new experimental tools or
modeling techniques to study interactions at the microbial
surface.
The purpose of this book is to provide an update on some of the latest research and applications in the broad field of ionic liquids. This volume spans research and development activities ranging from fundamental and experimental investigations to commercial applications. A brief history of the field is included, as well as both new developments and reviews organized in the general topical areas of applications, materials, biomass processing, and fundamental studies. This book attempts to propel the field forward by bringing together contributions from some of the foremost researchers on ionic liquids. Recent products and new large-scale processes using ionic liquids, both in operation and being announced, indicate that an exciting new chapter in this field is about to begin. The authors summarize some of the history, applications, conferences, books, databases, issues related to data quality and toxicity for researchers working in the field of ionic liquids and includes an overview for each proceeding chapter with an introduction about the authors.
This book offers a broad discussion of the concepts required to
understand the thermodynamic stability of molecules and bonds and a
description of the most important condensed-phase techniques that
have been used to obtain that information. Above all, this book
attempts to provide useful guidelines on how to choose the "best"
data and how to use it to understand chemistry. Although the book
assumes some basic knowledge on physical-chemistry, it has been
written in a "textbook" style and most topics are addressed in a
way that is accessible to advanced undergraduate students. Many
examples are given throughout the text, involving a variety of
molecules.
The field of quantum chemistry has grown so immensely that the importance of some of the earliest work and the earliest pioneers of quantum chemistry is unfamiliar to many of today's youngest scientists in the field. Thus, this book is an attempt to preserve some of the very valuable, early history of quantum chemistry, providing the reader with not only a perspective of the science, but a perspective of the early pioneers themselves, some of whom were quite interesting characters. The symposium on which this book is based came about because one of the co-editors (ETS) came to a conviction that the contributions such as those by George Wheland to quantum chemistry and Otto Schmidt to free electron theory should be better appreciated and known. He organized a symposium in which quantum chemistry pioneers, both those celebrated by everyone and those seemingly overlooked by posterity, would be recognized. While this volume is certainly not a history of quantum chemistry, it does cover many highlights over a period of about sixty years. This volume consists of chapters based upon ten of the presentations at the symposium "Pioneers of Quantum Chemistry" held March 28, 2011, at the 241st ACS National Meeting in Anaheim, CA.
Starting from a clear, concise introduction, the powerful finite element and boundary element methods of engineering are developed for application to quantum mechanics. The reader is led through illustrative examples displaying the strengths of these methods using applications to fundamental quantum mechanical problems and to the design/simulation of quantum nanoscale devices. |
