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.
Climate change is a major challenge facing modern society. The
chemistry of air and its influence on the climate system forms the
main focus of this book. Vol. 2 of Chemistry of the Climate System
takes a problem-based approach to presenting global atmospheric
processes, evaluating the effects of changing air compositions as
well as possibilities for interference with these processes through
the use of chemistry.
Environmental Fate and Safety Management of Agrochemicals discusses
residue analysis, environmental fate and safety management,
environmental risk assessment, metabolism, resistance and
management, and advances in formulation and application technology
from the academic, government, and industry perspective.
Meaningful ecological and environmental risk assessment of pest
control agents is possible only when accurate and credible
metabolic and environmental fate data is available. The advent of
affordable and sensitive liquid chromatography/mass spectrometry
(LC/MS) has greatly increased our ability to detect environmentally
relevant metabolites and degradation products following the
application of these materials. Furthermore, ecological risk
assessment and monitoring of pesticide resistance in field
populations has become more feasible and cost effective by
employing hig-hroughout molecular diagnostic techniques on the
genetic leve3l and LC/MS techniques on the proteomic and meabolomic
levels.
Efficient formulations and application technologies have greatly
reduced the amount of materials that are required to achieve
effective pest control and hence reduce their ecological and
environmental impacts. Controlled release, stabilization and
dispersion technologies have provided the pest manager with new
tools that allow them to use necessary pest control options in
"best management strategies."
The book gives an overview of the current state-of-the-art
concerning the activation and dissolution of cellulose in a broad
variety of solvents. Research on this topic can lead to new
pathways for the utilization of the most abundant terrestrial
biomolecule and may therefore be the basis for new green strategies
towards advanced materials. Leading scientists in the field show
different conceptions for the solubilization of cellulose. The long
history and groundbreaking developments in the field of polymer
chemistry, which are related to this subject, have lead to timely
alternatives to already established methods. In addition to
discussing attempts for the optimization of known dissolving
procedures, this book also details new solvent systems. New
solvents include inorganic and organic salt melts (ionic liquids),
new aqueous media, multi-component organic solvents and the
dissolution under partial derivatization of the polysaccharide. The
opportunities and the limitations of the solvents are demonstrated,
with a particular emphasis on the stability of the solutions and a
possible recycling of the solvent components.
This book illustrates that the new procedures for cellulose
dissolution can lead to a huge number of unconventional
superstructures of regenerated cellulose material, such as fibers
and polymer layers with a thickness in the nanometer range or
aerogels, i.e. regenerates with a highly porous character and a
large surface. Moreover, cellulose blends can be generated via
solutions. The book also contains chapters that show the amazing
potential of solvents for defined modification reactions on the
cellulose backbone. On one hand, it is possible to synthesize known
cellulose derivatives with new substitution patterns both on the
basis of the repeating unit and along the polymer chain. On the
other hand, completely new derivatives are presented which are
hardly accessible via heterogeneous reactions. Consequently, the
book is intended to give a comprehensive overview of procedures for
dissolution of cellulose. It is of interest for scientists new in
the field but is also a timely summary of trends for experts who
are looking for new approaches for problems related to cellulose
shaping or chemical modification.
One of the great challenges of the 21st century is that of
sustainability. This book aims to provide examples of
sustainability in a wide variety of chemical contexts, in hope of
laying the groundwork for cross-divisional work that might be
possible in the future to address the important issue of
sustainability. In doing so, the editors look at both the questions
chemistry is asking right now related to sustainability as well as
the questions chemistry SHOULD be asking about sustainability. The
world is facing interrelated global challenges of energy, food,
water, and human health. Solving these daunting challenges will
require global systems thinking and proactive local action. No ONE
company, academic institution, non-profit or government agency can
accomplish this task alone, but it starts with education at all
levels. This book addresses the need for better chemical education
on the subject of sustainability.
Unlike some other reproductions of classic texts (1) We have not
used OCR(Optical Character Recognition), as this leads to bad
quality books with introduced typos. (2) In books where there are
images such as portraits, maps, sketches etc We have endeavoured to
keep the quality of these images, so they represent accurately the
original artefact. Although occasionally there may be certain
imperfections with these old texts, we feel they deserve to be made
available for future generations to enjoy.
Challenges and Recent Advances in Sustainable Oil and Gas Recovery
and Transportation delivers a critical tool for today’s petroleum
and reservoir engineers to learn the latest research in EOR and
solutions toward more SDG-supported practices. Packed with methods
and case studies, the reference starts with the latest advances
such as EOR with polymers and EOR with CCS. Advances in shale
recovery and methane production are also covered before layering on
sustainability methods on critical topics such as oilfield produced
water. Supported by a diverse group of contributors, this book
gives engineers a go-to source for the future of oil and gas. The
oil and gas industry are utilizing enhanced oil recovery (EOR)
methods frequently, but the industry is also tasked with making
more sustainable decisions in their future operations.
