Скачать книгу - Selective Nanocatalysts and Nanoscience



Filling a gap in the catalysis and nano literature, this monograph is unique in focusing on both nanostructured heterogeneous and homogeneous catalysis. As such, it describes a selection of heterogeneous catalysts in use, showing that the dimension of the relevant portions of the catalysts are always in the 1-100 nm range, and so may be properly understood as nanomachines for the chemical manipulation of molecules to perform high precision selective synthesis. The prominent international authors then go on to show that the concept of nanoscience can be equally applied to artificial homogeneous catalysts whose active sites are generally considered as «single-sites» having a «molecular» dimension. The result is an excellent overview of such hot topics as nanoparticles, MOFs and more, making this indispensable reading for catalytic and organic chemists, as well as those working on organometallics.

Stereoselective Organocatalysis. Bond Formation Methodologies and Activation Modes Stereoselective Organocatalysis. Bond Formation Methodologies and Activation Modes

Автор: Ramon Torres Rios

Год издания: 

Sets forth an important group of environmentally friendly organic reactions With contributions from leading international experts in organic synthesis, this book presents all the most important methodologies for stereoselective organocatalysis, fully examining both the activation mode as well as the type of bond formed. Clear explanations guide researchers through all the most important methods used to form key chemical bonds, including carbon-carbon (C–C), carbon-nitrogen (C–N), and carbon-halogen (C–X) bonds. Moreover, readers will discover how the use of non-metallic catalysts facilitates a broad range of important reactions that are environmentally friendly and fully meet the standards of green chemistry. Stereoselective Organocatalysis begins with an historical overview and a review of activation modes in asymmetric organocatalysis. The next group of chapters is organized by bond type, making it easy to find bonds according to their applications. The first of these chapters takes a detailed look at the many routes to C–C bond formation. Next, the book covers: Organocatalytic C–N bond formation C–O bond formation C–X bond formation C–S, C–Se, and C–B bond formation Enantioselective organocatalytic reductions Cascade reactions forming both C–C bonds and C–heteroatom bonds The final chapter is devoted to the use of organocatalysis for the synthesis of natural products. All the chapters in the book are extensively referenced, serving as a gateway to the growing body of original research reports and reviews in the field. Based on the most recent findings and practices in organic synthesis, Stereoselective Organocatalysis equips synthetic chemists with a group of organocatalytic reactions that will help them design green reactions and overcome many challenges in organic synthesis.


Directed Evolution of Selective Enzymes. Catalysts for Organic Chemistry and Biotechnology Directed Evolution of Selective Enzymes. Catalysts for Organic Chemistry and Biotechnology

Автор: Manfred Reetz T.

Год издания: 

Authored by one of the world's leading organic chemists, this authoritative reference provides an overview of basic strategies in directed evolution and introduces common gene mutagenesis, screening and selection methods. Throughout the text, emphasis is placed on methodology development to maximize efficiency, reliability and speed of the experiments and to provide guidelines for efficient protein engineering. Professor Reetz highlights the application of directed evolution experiments to address limitations in the field of enzyme selectivity, substrate scope, activity and robustness. He critically reviews recent developments and case studies, takes a look at future applications in the field of organic synthesis, and concludes with lessons learned from previous experiments.


Surface Science. Foundations of Catalysis and Nanoscience Surface Science. Foundations of Catalysis and Nanoscience

Автор: Kurt W. Kolasinski

Год издания: 

Surface science has evolved from being a sub-field of chemistry or physics, and has now established itself as an interdisciplinary topic. Knowledge has developed sufficiently that we can now understand catalysis from a surface science perspective. No-where is the underpinning nature of surface science better illustrated than with nanoscience. Now in its third edition, this successful textbook aims to provide students with an understanding of chemical transformations and the formation of structures at surfaces. The chapters build from simple to more advanced principles with each featuring exercises, which act not only to demonstrate concepts arising in the text but also to form an integral part of the book, with the last eight chapters featuring worked solutions. This completely revised and expanded edition features: More than 100 new pages of extensive worked solutions New topics, including: Second harmonic generation (SHG), Sum Frequency Generation (SFG) at interfaces and capillary waves An expanded treatment of charge transfer and carbon-based materials including graphene Extended ‘Frontiers and Challenges’ sections at the end of each chapter. This text is suitable for all students taking courses in surface science in Departments of Chemistry, Physics, Chemical Engineering and Materials Science, as well as for researchers and professionals requiring an up-to-date review of the subject.
