Homogeneous asymmetric catalysis offers reliable results and the possibility to 'tune' the catalysis on a rational basis. A pitfall, however, is that the separation of the catalyst from the starting material and products is difficult and often results in the loss of the catalytic material. Immobilization offers a potential solution for the user of enantioselective catalysts in industrial processes and laboratories. Heterogeneous catalysis allows continuous operations, recycling of the catalyst, and an easy separation of the reaction products, reducing both waste and costs. Chemists in academia and industry will welcome this careful selection of topics in this handbook that provides readers with practical and detailed information about the technical requirements for the immobilization of chiral catalysts, their application in synthesis, and methods for recycling.

Your First Leadership Job. How Catalyst Leaders Bring Out the Best in Others
Автор: Tacy Byham M.
Год издания:
Becoming the Very Best First-Time Leader Congratulations! You’re now in charge. Perhaps it’s your first time as a leader, or maybe you want to fine-tune your skills. Either way, you’ve begun one of the most rewarding chapters of your career. But, like many beginnings, the first few years can be challenging. Fortunately, you don’t have to tackle this challenge on your own. Your First Leadership Job gives you practical advice straight from others who have walked in your shoes. Not only does it include dozens of tools to ensure your success, but it’s also based on the authors’ and DDI’s extensive experience and research, which ultimately has led to the development of millions of leaders around the world. In fact, a quarter-million leaders will be developed this year alone via DDI training. Your First Leadership Job is divided into two sections. Part 1 introduces the concept of catalyst leader—one who sparks energy, passion, and commitment in others. Your transition to catalyst leader is a major step in your leadership journey. This book provides essential tips to put you on the catalyst path. Ultimately, leadership is about the many conversations—frequent, clear, authentic, and occasionally difficult—that you will have daily. Your First Leadership Job builds awareness of the fundamental skills you’ll come to rely on to make every one of these interactions successful. Part 2 devotes 13 chapters to critical core leadership competencies, including coaching for success, hiring the best employees, turning dreaded appraisals into discussions that propel performance, and handling difficult employees. It also includes a chapter for first-time female leaders. Look at Your First Leadership Job as an indispensable companion to becoming an awesome leader—one who will make a positive, lasting impact on your team, family, and career.

Corporate Catalyst. A Chronicle of the (Mis)Management of Canadian Business from a Veteran Insider
Автор: Tony Griffiths
Год издания:
An inside look at the real business world In Corporate Catalyst, Tony Griffiths gives readers a ringside seat on the many boardroom and corporate battles that he both fought and witnessed through the nearly six decades of his productive and colorful career. Among other stories, Griffiths replays his two stints as the CEO of Canada's darling of the telecom industry, Mitel Corporation. The first was in the late 1980s, a time when he helped staunch the flow of red ink and returned the company to profitability. The second was in the early 1990s, when he steered the company through its majority ownership by British Telecom and then its sale to Schroder Ventures. As Griffiths relates it, he had to learn how to deal with the bureaucratic style of the former and the power-hungry moves of the latter. Corporate Catalyst includes the author's blow-by-blow account of what went on inside Confederation Life in the 1980s and early 1990s—a story that should have prevented the failure of the likes of Lehman Brothers in the recent Great Recession. Griffiths, who had his hands full at the time with challenges at Mitel, also sat on Confed's board. He tried to warn Confederation Life's executives and his fellow board members of the financial dangers the company was facing. No one but a few other board members would listen-and even they did not do so consistently. The fall of Confed Life became one of the largest failures of a major finance company in corporate history. Griffiths takes the reader on a dramatic tour of the trickery, betrayal, and politicking that the world of business seems to attract. He introduces readers to the biggest and boldest names in Canadian business, including Jake Moore of Brascan, Robert Campeau of Campeau Corporation, Terry Mathews of Mitel, Ted Rogers of Rogers Communications, Conrad Black of Hollinger, Adam Zimmerman of Noranda, Pat Burns of Confederation Life, and Christopher Ondaatje of The Ondaatje Corporation. In the book's many cautionary tales, Griffiths warns against mixing the roles of governance and management and shows the marked tendency of executives to take up residence far from reality when times get tough. «We don't listen. We don't plan. We don't act,» he wrote in frustration to the board and management of Confederation Life after months of trying to get someone to address the financial mess they were in. Full of hard-won wisdom, Corporate Catalyst is a must-read for anyone working in business or interested in what the business world is really like.

Mirror-Image Asymmetry. An Introduction to the Origin and Consequences of Chirality
Автор: James Riehl P.
Год издания:
An overview of the importance and consequences of asymmetry from molecules to the macroscopic world As scientists have become more capable of probing the structure of three-dimensional objects at the molecular level, the need to understand the concept and the consequences of mirror-image asymmetry—chirality—has increased enormously. Written at an introductory level, Mirror-Image Asymmetry provides an overview of the importance and effects of asymmetry from the atomic and molecular world of physics and chemistry to the organisms and structures that we see and use in our everyday life. The reader will develop a broad appreciation of three-dimensional asymmetry from the microscopic molecular world to the macroscopic world of handedness, automobile driving, windmills, sports, and similar phenomena. The book features: An introduction to basic definitions and the nomenclature of asymmetric and dissymmetric molecules Up-to-date examples of the importance and consequences of asymmetry in modern drug applications, current theories of the origin of asymmetry in nature, and examples of molecular asymmetry in smell, taste, and insect communication Many illustrations, chemical structures, and photographs that enable the reader to connect the actual asymmetrical structures to the different phenomena that depend on structural asymmetry In the 150 years since Louis Pasteur discovered asymmetry in molecular structures, scientists have made great progress in understanding how interactions between chiral molecules influence biochemical processes. This knowledge is leading to very sophisticated asymmetric synthetic techniques that have greatly benefitted many research groups especially those in the pharmaceutical industry. This guide to the role of molecular and macroscopic chirality will inspire students and scientists in chemistry, biology, physics, and drug discovery.
