Memoir 36 – The Geological Record of Neoproterozoic Glaciations
In recent years, interest in Neoproterozoic glaciations has grown as their pivotal role in Earth system evolution has become increasingly clear. One of the main goals of the IGCP Project number 512 was to produce a synthesis of newly available information on Neoproterozoic successions worldwide similar in format to Hambrey & Harlands (1981) Earths pre Pleistocene Glacial Record. This Memoir therefore consists of a series of overview chapters followed by site-specific chapters. The overview chapters cover key topics including the history of research on Neoproterozoic glaciations, identification of glacial deposits, chemostratigraphic techniques and datasets, palaeomagnetism, biostratigraphy, geochronology and climate modelling. The site specific chapters for 60 successions worldwide include reviews of the history of research on these rocks and up-to-date syntheses of the structural framework, tectonic setting, palaeomagnetic and geochronological constraints, physical, biological, and chemical stratigraphy, and descriptions of the glaciogenic and associated strata, including economic deposits.

Ecotoxicology of Amphibians and Reptiles, Second Edition by Greg Linder
English | June 2, 2010 | ISBN: 1420064169 | 944 Pages | PDF | 17 MB

Ecotoxicology of Amphibians and Reptiles, Second Edition by Greg Linder
Building on the success of its popular predecessor, the second edition of Ecotoxicology of Amphibians and Reptiles presents newly available findings on the species that are important environmental indicators. This new edition covers nearly twice as many topics as the first, including recent developments in the ecotoxicology of amphibians and reptiles, the current status of these animals, and intrinsic factors that affect their susceptibility to contaminants. The book also provides the latest information on specific groups of contaminants and their effects and body burdens in herpetafauna. After a review of how contaminants interact with other ecological factors, the text explores concerns for the future.

New in the second edition:

– New research on the effects of pesticides, heavy metals, endocrine disrupting chemicals, and UVB
– Increased focus on the effects of contaminants rather than merely reporting residue information
– A synthesis of information on atrazine and its effects on gonads at low concentrations
– Coverage of the potentially alarming new cadre of chemicals that have recently or are about to come on the market for which there is very little or no information
– Important advances in surveying and monitoring

One of the major factors behind the writing of the first edition was the worldwide phenomenon of declining amphibian populations. Although this decline has not abated, the breadth of research into its causes has expanded significantly. With chapter contributors carefully selected by the team of editors as leaders in their fields, this book provides an authoritative compendium of the most recent information on effects and residues coupled with a syntheses of what these numbers mean to science and policy.

New Trends in Cross-Coupling: Theory and Applications
Palladium-catalysed cross-coupling reactions constitute a powerful class of chemical methods for the creation of carbon-carbon and carbon-heteroatom bonds used in organic synthesis, famously recognized by the 2010 Nobel Prize awarded to Richard F. Heck, Ei-ichi Negishi and Akira Suzuki 'for palladium-catalysed cross-couplings in organic synthesis.' These methods have become ubiquitous in academic and industrial settings alike, as applications span from industrial production of pharmaceuticals, agrochemicals, polymers, and dyes to the synthesis of complex natural products. New Trends in Cross-Coupling provides the reader with the history and basic, concepts of cross-coupling up to the state of the art in modern coupling reactions from both technology and applied perspectives. A wide breadth of topics including selecting prominent ligand types; advances in Pd-phosphine precatalysts and Pd N-heterocyclic carbene complexes; new reactions such as carboiodination; implementation of new technologies such as continuous flow and advanced metal detection methods; greener approaches to cross-coupling; as well as large-scale applications in the syntheses of pharmaceutical materials are covered. Edited by Thomas J. Colacot, an Industrial expert on cross coupling, the book contains contributions from academic and industrial world leaders in the field as well as a Forewords from Professor Barry M. Trost, Gregory C. Fu and 2010 Nobel Laureate in Chemistry Professor Ei-ichi Negishi. New Trends in Cross-Coupling serves as a reference guide for both undergraduate and graduate students as well as those who are experts in the area. '…this compilation, a "Must" for anyone interested in learning and using newer trends in cross-coupling.'

Carbohydrate Chemistry: Proven Synthetic Methods, Volume 2 by Gijsbert van der Marel and Jeroen Codee
English | 2014 | ISBN: 1439875944 | 333 pages | PDF | 6 MB
Long gone are the days when synthetic publications included parallel preparative experiments to document reproducibility of the experimental protocols and when journals required such documentation.

Carbohydrate Chemistry: Proven Synthetic Methods, Volume 2
The new Proven Synthetic Methods Series addresses concerns to chemists regarding irreproducibility of synthetic protocols, lack of characterization data for new compounds, and inflated yields reported in many chemical communications-trends that have recently become a serious problem.
Volume One of Carbohydrate Chemistry: Proven Synthetic Methods includes more detailed versions of protocols previously published for the synthesis of oligosaccharides, C-glycosyl compounds, sugar nucleotides, click chemistry, thioglycosides, and thioimidates, among others. The compilation of protocols covers both common and less frequently used synthetic methods as well as examples of syntheses of selected carbohydrate intermediates with general utility. The major focus of this book is devoted to the proper practice of state-of-the-art preparative procedures, including:
* References to the starting materials used, reaction setup, work-up and isolation of products, followed by identification and proof of purity of the final material
* General information regarding convenience of operation and comments on safety issues
* Versatile and practically useful methods that have not received deserved, long-lasting recognition or that are difficult to access from their primary sources
* Copies of 1D NMR spectra of compounds prepared, showing purity of materials readers can expect
Exploring carbohydrate chemistry from the academic points of view, the Carbohydrate Chemistry: Proven Synthetic Methods Series provides a compendium of preparatively useful procedures checked by chemists from independent research groups.

Microwave-Assisted Organic Synthesis: A Green Chemical Approach

FREEDownload : Microwave-Assisted Organic Synthesis: A Green Chemical Approach

Suresh C. Ameta and Pinki B. Punjabi, "Microwave-Assisted Organic Synthesis: A Green Chemical Approach"
English | ISBN: 1771880392 | 2015 | 412 pages | PDF | 34 MB

Microwave-Assisted Organic Synthesis: A Green Chemical Approach
The large-scale production of chemicals to meet various societal needs has created environmental pollution, including pollution from byproducts and improper disposal of waste. With the world facing adverse consequences due to this pollution, green chemistry is increasingly being viewed as a means to address this concern.

Since most organic syntheses require toxic solvents, more reaction time, and drastic conditions of temperature, conventional methods of organic synthesis are less preferred. Microwave-assisted organic synthesis is considered to be a promising green chemical approach because it reduces reaction time from days or hours to minutes or even seconds, and has many other advantages. It helps reduce side reactions and increase yields, uses fewer solvents or is almost solvent-free, has solid supported reactions, and improves purity.

This book’s main focus is microwave-assisted organic synthesis processes, particularly various reactions such as cycloaddition, rearrangement, elimination, substitution, oxidation, reduction, condensation, coupling, polymerization, nanomaterials, synthesis of heterocycles, and industrial applications under microwave irradiation. The time is not far off when this methodology will virtually replace existing and cumbersome methods of organic synthesis.
