In 1984 a doomsday vault was constructed on a remote island in the Arctic Ocean. Its purpose was to preserve Earth's genetic history in the event of a global catastrophe. Now, decades later, a second vault has been uncovered. This one resting where no one ever expected. And the problem is...it's not ours. Yet even more curious than the vault itself, is what lies inside. Seeds. Millions of seeds. Each with a genetic embryo untouched and perfectly preserved. Waiting. No one knows who built it. Or when. What we have managed to figure out is that whoever it was traveled an immense distance. For the sole purpose of hiding their genetic blueprints on Earth. But why? Now a small group of marine biologists and navy investigators have been assigned to find out. Before anyone else does. But Alison Shaw and John Clay are not prepared for what they are about to uncover. Beginning with the truth behind our own evolution.

PROTON EXCHANGE MEMBRANE FUEL CELLS Edited by one of the most well-respected and prolific engineers in the world and his team, this book provides a comprehensive overview of hydrogen production, conversion, and storage, offering the scientific literature a comprehensive coverage of this important fuel. Proton exchange membrane fuel cells (PEMFCs) are among the most anticipated stationary clean energy devices in renewable and alternative energy. Despite the appreciable improvement in their cost and durability, which are the two major commercialization barriers, their availability has not matched demand. This is mainly due to the use of expensive metal-catalyst, less durable membranes, and poor insight into the ongoing phenomena inside proton exchange membrane fuel cells. Efforts are being made to optimize the use of precious metals as catalyst layers or find alternatives that can be durable for more than 5000 hours. Computational models are also being developed and studied to get an insight into the shortcomings and provide solutions. The announcement by various companies that they will be producing proton exchange membrane fuel cells-based cars by 2025 has accelerated the current research on proton exchange membrane fuel cells. The breakthrough is urgently needed. The membranes, catalysts, polymer electrolytes, and especially the understanding of diffusion layers, need thorough revision and improvement to achieve the target. This exciting breakthrough volume explores these challenges and offers solutions for the industry. Whether for the student, veteran engineer, new hire, or other industry professionals, this is a must-have for any library.

This Symposium on Catalyst Deactivation ensues those held at Berkeley (1985), Antwerp (1980) and Berkeley (1978). The three main topics emphasised at this most recent symposium were: the techniques used in deactivation studies, the mechanisms of catalyst deactivation, and modelling. With respect to the first, it became apparent that the study of deactivation faces even more difficulties than the characterization of fresh catalysts and the measurement of activity or selectivity, due to the multiplicity of interacting processes occurring during deactivation. Quite substantial progress has been made recently in the understanding of the mechanisms of various deactivation processes, particularly coking, and extra time was accorded to these topics at the symposium. The third topic corresponds to a problem which is very central to development studies and to the chemical engineering aspect of catalysis: it deals with the representativity of accelerated tests and the modelling of the deactivation phenomena.

Transition metal catalysis belongs to the most important chemical research areas because a ubiquitous number of chemical reactions are catalyzed by transition metal compounds. Many efforts are being made by industry and academia to find new and more efficient catalysts for chemical processes. Transition metals play a prominent role in catalytic research because they have been proven to show an enormous diversity in lowering the activation barrier for chemical reactions. For many years, the search for new catalysts was carried out by trial and error, which was costly and time consuming. The understanding of the mechanism of the catalytic process is often not very advanced because it is difficult to study the elementary steps of the catalysis with experimental techniques. The development of modern quantum chemical methods for calculating possible intermediates and transition states was a breakthrough in gaining an understanding of the reaction pathways of transition metal catalyzed reactions. This volume, organized into eight chapters written by leading scientists in the field, illustrates the progress made during the last decade. The reader will obtain a deep insight into the present state of quantum chemical research in transition metal catalysis.

Brokenness has become a buzzword. We wear it like a badge, proudly showing off the shattered pieces of our lives--while still fighting the same desperate battles. But brokenness was never meant to be the destination. Or your identity. It was meant to be the catalyst for breakthrough. Inspiring, vulnerable, and powerful, this new book from Jennifer Watson helps you take your eyes off the idol of brokenness and experience the God of breakthrough. She shows how breakthrough is really hope moving forward, even when life hurts. And she gives you practical, uncomplicated ways to: · stop feeling shame and emptiness · leave the victim mentality behind · experience lasting restoration in your story and your soul · and more It's okay to not be okay for a little while. But Jesus has a plan to see your scars become success stories that reflect his glory to the people around you.

Handbook of Spent Hydroprocessing Catalysts, Second Edition, covers all aspects of spent hydroprocessing catalysts, both regenerable and non-regenerable. It contains detailed information on hazardous characteristics of spent and regenerated catalysts. The information forms a basis for determining processing options to make decisions on whether spent catalysts can be either reused on refinery site after regeneration or used as the source of new materials. For non-regenerable spent catalysts, attention is paid to safety and ecological implications of utilizing landfill and other waste handling and storage options to ensure environmental acceptance. As such, this handbook can be used as a benchmark document to develop threshold limits of regulated species. Includes experimental results and testing protocols which serve as a basis for the development of methodologies for the characterization of solid wastes Presents a database which assists researchers in selecting/designing research projects on spent catalysts, i.e., regeneration vs. rejuvenation and metal reclamation Provides the environmental laws, acts, and liabilities to raise awareness in safety and health issues in all aspects of spent catalysts Contains solid waste management procedures specific to hydroprocessing that serve as a model for designing research projects in other solid waste areas

This book offers an overview of the state of the art in the field of DeNOx catalysis in order to focus novel orientations, new technological developments, from laboratory to industrial scale. A particular attention has been paid towards the implementation of catalytic processes for minimising NOx emissions either from stationary or mobile sources under lean condition to meet future standard regulations of NOx emissions. In the first part of this book, critical aspects reported in the literature which usually make difficult the achievement of efficient catalytic technologies in those conditions are summarised and analysed in order two separate new perspectives. The second part deals with fundamental aspects at molecular level. A better understanding of the reactions involved under unsteady-state conditions is probably a pre-requisite step for improving the performances of the actual processes or developing original ones. The development of powerful in situ spectroscopic techniques is of fundamental interest for kinetic modelling. Correlations between spectroscopic and kinetic data with those obtained from theoretical calculations are reported. Some illustrations emphasise the fact that these comparisons may help in determining the nature of the catalytic active sites and building predictive tools for simulations under running conditions. The latter part of this book will be illustrated by different practical approaches covering various aspects related to the catalysts preparation and the development of alternative technologies which include industrial considerations. - New technological developments for investigating catalytic reactions in transient conditions (in situ and operando spectroscopic techniques) - Concerted approaches in DeNOx catalysis - How academic aspects (kinetic, in situ spectroscopic measurements) can provide useful information for practical applications - Comparison of different approaches provided by academic and industrial partners
