Mass Spectrometry

Mass Spectrometry

It is estimated that there are about 10 million organic chemicals known and about 100 000 new organic compounds are produced each year. Some of these new chemicals are made in the laboratory and some are isolated from natural products. The structural determination of these compounds is the job of the chemist. There are several instrumental techniques used to determine the structures of organic compounds. These include NMR UV/visible infrared spectroscopy mass spectrometry and X-ray crystallography. Of all the instrumental techniques listed infrared spectroscopy and mass spectrometry are the two most popular techniques mainly because they tend to be less expensive and give us the most structural information. This book is an introductory text designed to acquaint undergraduate and graduate students with the basic theory and interpretative techniques of mass spectrometry. Much of the material in this text has been used over a period of several years for teaching courses in materials characterization and chemical analysis. It presents the mass spectra of the major classes of organic compounds and correlates the fragmentation pattern of each spectrum with the structural features of the compound it represents. This has been done for hydrocarbons organic acids ketones aldehydes esters anhydrides phenols amines and amides. The text discusses the origin of the fragments techniques innovations and applications in mass spectrometry. It is interspersed with many illustrations examples an adequate but not overwhelming bibliography and problems for students. It will serve as a lecture text for a one-semester course in mass spectrometry or can be used to teach the mass spectra portion of a broader course in material characterization and chemical analysis.

Fundamentals of Solar Radiation

Fundamentals of Solar Radiation

The sun radiates a tremendous amount of energy called solar energy or solar radiation which is the main natural source of energy on the Earth by far. Because solar radiation is the almost unique supplier of energy to the Earth it has a primary influence on life and activities on the Earth. The climate is a first example but there are many others such as plant growth or human health or even the design of buildings the production of energy notably electrical and thermal or even aging materials. This book aims to provide simple answers to anyone who has questions about solar radiation. Its ambition is to help by presenting the fundamental elements of the solar radiation received on the ground. The book includes many examples and numerous illustrations as well as some simple but fairly precise equations to calculate the various elements covered and to reproduce the figures and graphs. The first of the three parts of this book is devoted to the relative geometry between the direction of the sun and an observer on the ground as well as to the solar radiation emitted by the sun and received at the top of the atmosphere. The orbit of the Earth around the sun and the solar declination are described. The concept of time is introduced which is closely linked to the solar cycle and the rotation of the Earth on itself. Equations are given to calculate the solar radiation received on a horizontal or inclined surface located at the top of the atmosphere. The spectral distribution of the extraterrestrial solar radiation is described. The second part of this book addresses how the solar radiation incident at the top of the atmosphere is attenuated and modified in its downward path to the ground. The reflection of the radiation by the ground is presented. The solar radiation received on the ground by a horizontal or inclined collector plane such as a natural slope or a rooftop is discussed as well as its spectral distribution. The variability of the radiation is addressed in relation to the properties of solar radiation estimated from the measurements. The third part deals with direct or indirect measurements of the solar radiation received on the ground over a given integration time (minute hour day or month) whether for total radiation or radiation in a spectral range such as ultraviolet (UV) or daylight or photosynthetically active radiation (PAR). It also explains how to check the plausibility of the measurements. Fundamentals of Solar Radiation will be a valuable resource to all professionals engineers researchers students and other practitioners that seek an understanding of solar radiation.

Biology and Biotechnology of Environmental Stress Tolerance in Plants 3-Volume Set

Biology and Biotechnology of Environmental Stress Tolerance in Plants 3-Volume Set

This new 3-volume set provides a comprehensive understanding of the mechanisms that mediate biosynthesis accumulation and degradation of plant metabolites so as to employ novel strategies to improve crop production and enhance abiotic stress tolerance in plants. Abiotic stresses such as drought high salt cold heat UV radiation heavy metal pollution etc. are increasingly responsible for restricting plant growth and agricultural production and are becoming more alarming due to threats from global climate change. To combat these threats it is imperative to study the underlying mechanisms of stress tolerance from diverse metabolites and the biosynthesis pathways for metabolite production to maintain osmotic balance under diverse environmental stresses. Biology and Biotechnology of Environmental Stress Tolerance in Plants provides that understanding. Volume 1: Secondary Metabolites in Environmental Stress Tolerance focuses exclusively on the diverse secondary metabolites that play a major role in the adaptation of plants to the environment and in overcoming stress conditions as well as their implications in enhancing tolerance mechanisms. The chapters in this section review and integrate the currently available information on the protective role rendered by a wide array of antioxidative secondary metabolites and their regulation during diverse environmental stress. Volume 2: Trace Elements in Environmental Stress Tolerance throws light on the different inorganic trace elements including metal nanoparticles that help to deal with various environmental stresses. While these elements at high level create considerable phytotoxicity and halt metabolic and enzymatic activity they also promote growth and development in limited quantity so that they have significant potential in revamping plant morphology and physiology under stressed conditions. Hence optimum concentration management of these elements can help to mitigate world hunger and contribute toward sustainable agriculture and food security under challenging environments. Volume 3: Sustainable Approaches for Enhancing Environmental Stress Tolerance focuses on the agronomic and biochemical approaches as well as biotechnological and high-throughput technologies including the prospects of genetic engineering epigenetics and the latest CRISPR/Cas technology in generating stress-tolerant plants. The volume provides a clear road map for the implementation of techniques for improving abiotic stress tolerance in plants for better sustenance. Key features: Provides an advanced understanding of the mechanisms of action of secondary metabolites and trace elements in environmental stress tolerance as well as the different agronomic and biotechnological methods that enhances stress tolerance Looks at the overall metabolic pathways and genetic engineering giving a holistic view of plant-level studies of diverse abiotic stresses affecting different metabolic pathways Provides the groundwork to help researchers in designing future programs for identifying novel genes and proteins and targeting proper pathways to develop climate-resilient plants Altogether the three-volume Biology and Biotechnology of Environmental Stress Tolerance in Plants will enhance our understanding of plant responses to environmental stresses and enable implementation of programs and practices that can help us to develop climate-resilient plants with better performance for better yield and quality. | Biology and Biotechnology of Environmental Stress Tolerance in Plants 3-Volume Set
