Book Description
The present Special Issue of Symmetry is devoted to two important areas of global Riemannian geometry, namely submanifold theory and the geometry of Lie groups and homogeneous spaces. Submanifold theory originated from the classical geometry of curves and surfaces. Homogeneous spaces are manifolds that admit a transitive Lie group action, historically related to F. Klein's Erlangen Program and S. Lie's idea to use continuous symmetries in studying differential equations. In this Special Issue, we provide a collection of papers that not only reflect some of the latest advancements in both areas, but also highlight relations between them and the use of common techniques. Applications to other areas of mathematics are also considered.

Elaboration And Applications Of Metal-organic Frameworks
Author: Shengqian Ma
Publisher: World Scientific
ISBN: 9813226749
Category : Science
Languages : en
Pages : 730
Book Description
This title takes researchers in as well as out of the field of metal-organic framework (MOF) and then guides them on a journey to rediscover and rethink how these designer coordination polymers will influence the realm of materials science. This book opens with a look at a deeply controversial issue, MOF stability, which has plagued many systems, but ultimately has led to better materials that proved to be more robust allowing them to be investigated for multiple applications. This book successfully highlights many of these useful applications that MOFs are well adapted for. Because MOF components, inorganic and organic, can combine the best of both chemical domains, MOFs will improve our environment by removing harmful contaminants from the air and water, reduce the energy required to perform chemical reactions, partition hard to separate molecular mixtures, and form the next-generation of magnetic and electronic materials. MOFs will eventually be used for everyday activities — for monitoring or reacting to changing conditions. Readers of this book can then take note and implement MOFs in their line of research.

The Non-halogenated Flame Retardant Handbook
Author: Alexander B. Morgan
Publisher: John Wiley & Sons
ISBN: 1118939204
Category : Technology & Engineering
Languages : en
Pages : 314
Book Description
A one-stop, practical handbook containing all of the current commercial non-halogenated flame retardant technologies as well as experimental systems near commercialization In response to the emphasis on replacing halogenated flame retardants with alternate technologies, this handbook focuses on existing non-halogenated flame retardants and the experimental close-to-production systems that are available today. The Non-Halogenated Flame Retardant Handbook starts with an overview of the regulations and customer perceptions driving non-halogenated flame retardant selections over older halogenated technologies. It then moves on to cover the known major classes of non-halogenated flame retardants, before concluding with the current niche-performing technologies and untried commercial contenders of the future. The Non-Halogenated Flame Retardant Handbook: Takes a practical approach to addressing the narrow subject of non-halogenated flame retardancy—placing more emphasis on flame retardant selection for specific plastics, practical considerations in flame retardant material design, and the various technologies’ strengths and limits Focuses on the proper use of non-halogenated flame retardants, rather than the mechanics of how they work Discusses important future trends in flame retardancy Features sections written by industrial and chemical experts who know how to apply the technology to polymers for fire safety needs

Chemistry and Application of H-Phosphonates
Author: Kolio D. Troev
Publisher: Elsevier
ISBN: 008047649X
Category : Science
Languages : en
Pages : 308
Book Description
Chemistry and Application of H-Phosphonates is an excellent source for those planning the synthesis of new phosphorus-containing compounds and in particular derivatives containing a phosphonate, phosphoramide or phosphonic acid diester group. The rich chemistry, low cost and easy availability of diesters of H-phosphonic acid makes them an excellent choice as synthone in a number of practically important reactions. Phosphonic acid esters are intermediates in the synthesis of important classes of compounds such as alpha-aminophosphonic acids, bisphosphonates, epoxyalkylphosphonates, alpha-hydroxyalkylphosphonates, phosphoramides, poly(alkylene H-phosphonate)s, poly(alkylene phosphate)s, nucleoside H-phosphonates. The synthesis of each of these compound classes is reviewed in detail. Alpha-Aminophosphonic acids are an important class of biologically active compounds, which have received an increasing amount of attention because they are considered to be structural analogues of the corresponding Alpha-amino acids. The utilities of alpha-aminophosphonates as peptide mimics, haptens of catalytic antibodies, enzyme inhibitors, inhibitors of cancers, tumours, viruses, antibiotics and pharmacologic agents are well documented. Alpha-Hydroxyalkanephosphonates are compounds of significant biological and medicinal applications. Dialkyl epoxyalkylphosphonates are of interest because of their use as intermediates in the synthesis of bioactive substances, and as modifiers of natural and synthetic polymers. Bisphosphonates are drugs that have been widely used in different bone diseases, and have recently been used successfully against many parasites. Poly(alkylene H-phosphonate)s and poly(alkylene phosphate)s are promising, biodegradable, water soluble, new polymer-carriers of drugs. Nucleoside H-phosphonates seem to be the most attractive candidates as starting materials in the chemical synthesis of DNA and RNA fragments. The 5'-hydrogen phosphonate-3'-azido-2',3'-dideoxythimidine is one of the most significant anti-HIV prodrug, which is currently in clinical trials. Chapters review the synthesis; physical and spectral properties (1H, 13C, 31P and 17O NMR data); characteristic reactions; important classes of compounds based on these esters of H-phosphonic acid; their application as physiologically active substances, flame retardants, catalysts, heat and light stabilizers, lubricants, scale inhibitors, polymer-carriers of drugs; preparation of H-phosphonate diesters and general procedures for conducting the most important reactions.* provides ideas for the synthesis of phosphonates, phosphoramides and diesters of phosphonic acid (new phosphorus-containing compounds)* reviews structure, spectra and biological activity of H-phosphonates and their derivatives* examines new areas of application of phosphorus-containing compounds
