Organikum

Der "Klassiker" zur präparativen organischen Chemie beinhaltet alles, was für das Arbeiten im Labor wichtig ist - von theoretischen Grundlagen, Arbeitstechniken und Synthesplanung, Arbeitsvorschriften zu wichtigen Reaktionen und Produkten bis zu spektroskopischen Daten sowie Gefahren- und Sicherheitshinweisen. Für die 24. Auflage wurde das Buch vollständig überarbeitet, Versuchsanleitungen und Literaturhinweise in den einzelnen Kapiteln aktualisiert und neue Entwicklungen z.B. in der Analytik und Literatur-Recherche aufgenommen. Das Herzstück des "Organikums", der organisch-präparative Teil, wurde um weitere vorher getestete Arbeitsvorschriften für neue Reaktionen und Produkte ergänzt, z.B. übergangsmetallkatalysierte und -vermittelte C-C- und C-N-Bindungsknüpfungen, u.a. zu Biarylen (Suzuki-Miyaura-Kupplung), zu substituierten Olefinen (McMurry-Kupplung), zur Ringschlussmetathese oder zur Darstellung substituierter Aniline durch Buchwald-Hartwig-Reaktion. Weiterhin wurden die Baeyer-Villiger-Oxidation, Parikh-Doering-Reaktion, Birch-Reduktion und die Organokatalyse am Beispiel der Aldolreaktion aufgenommen. Eingeführt wurde auch das neue Einstufungs- und Kennzeichnungssystem für Chemikalien nach GHS. Im Reagenzienanhang wurden die H- und P-Sätze eingefügt, und der Gefahrstoffanhang wurde unter Anwendung der CLP-Verordnung neu bearbeitet. Für jeden Chemiker, ob Anfänger oder Fortgeschrittener, ob Student oder Chemiker in der Forschung oder Industrie, ist das "Organikum" ein unentbehrliches Nachschlagewerk mit wertvollen Tipps und Informationen für die erfolgreiche Laborarbeit.

Adopt distributed technology to deliver immutable data ownership solutions KEY FEATURES ● Understand how Blockchain is the backbone of bitcoin and smart contracts.● Complete coverage across distributed systems, blockchain frameworks, smart contracts and wallet.● Includes use-cases and current trends on the adoption of blockchain across different business models. DESCRIPTION This book is about developing a comprehensive understanding of blockchain, how it works and can benefit the functioning of the organization. This book exposes you to blockchain technology and illustrates how to leverage it to create value. First, you should have a working grasp of cryptography, cypher modes, digital signatures, and digital certificates, all of which are thoroughly covered in the first chapter of this book. By gradually introducing you to Distributed Ledger Technology, you can start understanding blockchain. After that, you'll become acquainted with fundamental blockchain concepts like consensus models, algorithms, and procedures. You'll learn about blockchain platforms such as Ethereum and Hyperledger Fabric that enable the development of DApps, DeFi applications, and systems driven by blockchains. Additionally, concepts such as smart contracts, the Ethereum virtual machine, accounts, wallets, GAS, and mining are explained briefly and simplified. The book analyses current blockchain developments, various blockchain as a Service (BaaS) platforms and helps you to gain a better grasp of the technology. Throughout the book, you will understand multiple blockchain principles, procedures, tools, and platforms required to begin developing blockchain-based business networks. WHAT YOU WILL LEARN● Acquaint yourself with the blockchain's application cases and primary benefits.● Consensus models, distributed networks, and cryptography techniques are well-understood.● Recognize how smart contracts and cryptocurrencies work.● Familiarize yourself with the HyperLedger Fabric and Ethereum.● Examine the Blockchain-as-a-Service (BaaS) model, platform, user interfaces, infrastructure, and network. WHO THIS BOOK IS FORThis book is intended for prospective blockchain developers, technical consultants, and anybody who is interested in learning and exploring the principles of blockchain technology, including the distributed systems, networking, cryptography, and smart contracts. Having prior knowledge around IT systems would be preferred.
