Download or read book Active Sites of Polymerization written by Gennady Zaikov and published by CRC Press. This book was released on 2005-03-28 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: The monograph is intended to systematize data on active sites and their kinetic and stereospecific heterogeneity (polysite phenomenon) in olefin and diene monomer ion, ion-coordination and complex radical polymerization processes. Questions of molecular-mass distribution of polymers obtained by ion and ion-coordination polymerization methods are discussed together with composition and stereo regularity distribution of olefin copolymers. Data on the influence of transition and non-transition metal origin and their ligand ambience, conditions of catalytic system preparation and polymerization are shown. Various assessment methods of polymerization active site distribution by kinetic activity and stereospecific action are considered. In particular, an assessment method for kinetic activity distribution at ion-coordination diene polymerization is described, mathematical simulation parameters for polymerization processes are shown, taking into account the polysite structure of catalytic systems. Of special attention are geometrical and electron structure of active sites in the ion-coordination polymerization by the quantum chemistry method, interrelation between reactivity of some types of active sites and stereospecificity of their action in diene polymerization. The importance of ratio between specific time elementary act duration at the diene injection, coordinated on an active site, and time of propagating macrochain end unit existence in the s-state at polydiene microstructure formation is indicated. Questions of the polysite mechanism occurrence in complex radical polymerization processes are discussed. A possibility for polymerization to proceed in both free-radical and complex related chain propagation sites is shown.

Download or read book The Value of Active Active Sites with Q Replication for IBM DB2 for z OS An Innovative IBM Client s Experience written by Serge Bourbonnais and published by IBM Redbooks. This book was released on 2015-01-23 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Any business interruption is a potential loss of revenue. Achieving business continuity involves a tradeoff between the cost of an outage or data loss with the investment required for achieving the recovery point objective (RPO) and recovery time objective (RTO). Continuous system availability requires scalability, as well as failover capability for maintenance, outages, and disasters. It also requires a shift from standby to active-active systems. Active-active sites are geographically distant transaction processing centers, each with the infrastructure to run business operations and with data synchronized by using database replication, such as the Q Replication technology that is part of IBM® InfoSphere® Data Replication software. This IBM Redbooks® publication describes preferred practices and introduces an architecture for continuous availability and disaster recovery that is used by a very large business institution that runs its core business on IBM DB2® for z/OS® databases. This paper explains the technologies and procedures that are required for the implementation of an active-active sites architecture. It also explains an innovative procedure for major IT upgrades that uses Q Replication for DB2 on z/OS, Multi-site Workload Lifeline, and Peer-to-Peer Remote Copy/Extended Distance (PPRC-XD). This paper is of value to decision makers, such as executive and IT architects, and to database administrators who are responsible for design and implementation of the solution.

Download or read book Iron and Cobalt Catalysts written by Wilson D. Shafer and published by MDPI. This book was released on 2020-06-23 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the turn of the last century when the field of catalysis was born, iron and cobalt have been key players in numerous catalysis processes. These metals, due to their ability to activate CO and CH, haev a major economic impact worldwide. Several industrial processes and synthetic routes use these metals: biomass-to-liquids (BTL), coal-to-liquids (CTL), natural gas-to-liquids (GTL), water-gas-shift, alcohol synthesis, alcohol steam reforming, polymerization processes, cross-coupling reactions, and photocatalyst activated reactions. A vast number of materials are produced from these processes, including oil, lubricants, waxes, diesel and jet fuels, hydrogen (e.g., fuel cell applications), gasoline, rubbers, plastics, alcohols, pharmaceuticals, agrochemicals, feed-stock chemicals, and other alternative materials. However, given the true complexities of the variables involved in these processes, many key mechanistic issues are still not fully defined or understood. This Special Issue of Catalysis will be a collaborative effort to combine current catalysis research on these metals from experimental and theoretical perspectives on both heterogeneous and homogeneous catalysts. We welcome contributions from the catalysis community on catalyst characterization, kinetics, reaction mechanism, reactor development, theoretical modeling, and surface science.

Download or read book Dynamic Chemical Processes on Solid Surfaces written by Ken-ichi Tanaka and published by Springer. This book was released on 2017-02-07 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, the author determines that a surface is itself a new material for chemical reaction, and the reaction of the surface provides additional new materials on that surface. The revelation of that peculiarity is what makes this book different from an ordinary textbook, and this new point of view will help to provide a new impetus when graduate students and researchers consider their results. The reaction of surface atoms provides additional new compounds, but these compounds cannot be detached from the surface. Some compounds are passive, but others work as catalysts. One superior feature of the surface is the dynamic cooperation of two or more different functional materials or sites on the same surface. This fact has been well established in the preferential oxidation of CO on platinum supported on a carbon nanotube with Ni-MgO at its terminal end. The Pt and Ni-MgO are perfectly separated, but these two are indispensable for the selective oxidation of CO in H2, where the H2O molecule plays a key role. The reader will understand that the complexity of catalysis is due to the complexity of the dynamic processes on the surface.
