Book Description

In the early twentieth century the relevance of chirality to the pharmaceutical industry was established by the fact that one enantiomer of hyoscyamine possessed greater pharmacological activity than the other. Today, most new drugs and those under development consist of a single optically active isomer, and chirality is also becoming an issue for the agrochemical and other industries. Regulatory agencies throughout the world are currently reviewing the importance of chirality with regard to pharmaceutical and agrochemical products. New guidelines from such agencies have been key drivers for the focus on single enantiomer products in these industries.

These scientific and regulatory developments have created the need for a guide for workers in the pharmaceutical and chemical industries seeking information on chiral molecules, processes, and commercially available chiral chemicals. Chiral Intermediates presents the chemical professional with a comprehensive listing of over 4700 available chiral chemicals including specific data of interest for each entry in the listing. Its companion volume, Chiral Drugs presents the same detailed information for over 2000 chiral drugs.

The 'Chiral Pool' of readily available, relatively inexpensive chiral compounds has been expanding at a rapid rate as more and more products are produced in large quantities at economical prices. New developments in various technologies for isolating, preparing, and purifying chiral materials have greatly increased the opportunities for utilizing optically pure compounds in commercial applications. Novel techniques for classical resolution, new methodologies for developing selective enzymes for biocatalysis, advances in the application of microorganisms for chemical production, and continued progress in the area of asymmetric synthesis have all contributed to the growth of this field.

Part I contains four chapters which provide an introduction to topics relevant to the field of chiral chemistry and includes a brief overview of chirality, a short discussion on the current market drivers in the area of chiral chemistry, and a basic presentation of the various sources and methods for obtaining chiral compounds.

Part II presents entries for 4700 commercially available chiral compounds. For each main entry, the chemical name and a list of trade names and synonyms is provided; the CAS Registry Number, the European Inventory of Existing Commercial Chemical Substances (EINECS) number, and the Merck Index (12th edition) number are given when available. The physical properties, including specific rotation, of each compound are described and indicated applications are presented. The structure of nearly every compound is provided, and the manufacturers and suppliers of the compounds are also given. Indexes, including a master index of names and synonyms and an index of custom manufacturing services for production of chiral compounds, are appended.

Chiral Intermediates provides an introduction to the types of sources and methods currently in use for obtaining chiral molecules and is an invaluable resource for information on available chiral molecules. Chiral Intermediates and Chiral Drugs are the most comprehensive and detailed guides to chiral compounds available. ... Read more

Book Description

This third volume completes the first part of the project " Macromolecular Physics." The first volume dealt with the description of macromolecular crystals; the second volume dealt with crystal growth; and the third volume summarizes our knowledge of the melting of linear, flexible macromolecules. The discussion in the three volumes goes from reasonably well-established topics, such as the structure, morphology, and defects in crystals, to topics still in flux, such as crystal nucleation, detailed growth mechanisms, and annealing processes, to arrive at the present topics of equilibrium, nonequilibrium, and copolymer melting.Our knowledge is quite limited on many aspects of these latter topics. ...

Book Description

Atomic and Molecular Photoabsorption, Volume 1 describes and catalogs available spectral information relevant to how common gases interact with sunlight and other sources of electromagnetic radiation such as x-rays, flames, and plasmas. Photoabsorption is light's reduction in intensity and force when it passes through a column of gas or liquid. This book also includes a large number of data tables and figures that are invaluable to researchers because they help them select exactly which wavelengths to use in their experiments. The further distinguishing aspect of this book is its synthesis across a broad spectrum of wavelengths and compilation of data for a large number of atoms and molecules. ... Read more

Book Description

Recent advances in scanning-probe technology, in optical technology (optical "tweezers"), and in solution-phase chemistry now enable us to manipulate individual atoms and molecules. It is thus becoming possible not only to build machines at the scale of integrated electronic circuits and circuits with "wires" no thicker than an atom, but also to manipulate biological tissues and materials at the scale of individual cells, organelles, and even molecules. The implications of this technology are profound: for computer technology, for electromechanical sensors and actuators, for materials science and manufacturing, and for biomedical engineering.||The molecular machines of living organisms provide the paradigm for the discussion in this text. It thus emphasizes chemical physics, particularly solution-phase chemistry, as a basis for understanding the assembly of molecular machines. In addition, the book discusses the proximity-probe methods and bioengineering associated with understanding and designing devices at nanometer scales.||"Molecular Nantechnology " will be of interest to physicists, chemists, materials scientists, biological physicists, computer scientists, and manufacturing engineers.

||From the reviews:||"[Provides] an intuitive, scientific framework for understanding nanoscale systems . . . Rietman had organized the book around his precept that 'solution-phase chemistry and protein engineering will bootstrap us into the first phase of nanotechnology.' . . . Useful for those who might need a basic introduction to some of the important issues in nanotechnology and the influence of the chemical and biological science on the nanotechnology revolution . . . Those seeking a qualitative picture of nanoscale systems engineering will find it a useful reference."|-Physics Today

For low temperature experiments.
This is the first book, I came across, in low temperature techniques. Useful for people carrying out low temperature experiments. This book does not deal with ultra low temperatures, that is temperatures below 1K, adequately. Does not write about the modern dilution refrigeratures. However, if one needs some low temperature technique information or low temperaure material data, then one can look in to this book. The book is very clearly written and still useful, although several new books on this topic have been published. ... Read more

Book Description

Quantum Systems in Chemistry and Physics contains a refereed selection of the papers presented at the first European Workshop on this subject, held at San Miniato, near Pisa, Italy, in April 1996.The Workshop brought together leading experts in theoretical chemistry and molecular physics with an interest in the quantum mechanical many-body problem. This volume provides an insight into the latest research in this increasingly important field. Throughout the Workshop, the emphasis was on innovative theory and conceptual developments rather than on computational implementation. The various contributions presented reflect this emphasis and embrace topics such as density matrices and density functional theory, relativistic formulations, electron correlation, valence theory, nuclear motion, response theory, condensed matter, and chemical reactions.Audience: The volume will be of interest to those working in the molecular sciences and to theoretical chemists and molecular physicists in particular. ...
