Design of new processes that avoid the use of toxic reagents has been the focus of intense research of late. Catalysis by metals and non-metals offers diverse opportunities for the development of new organic reactions with promising range of selectivities-chemoselectivity, regioselectivity, diastereoselectivity, and enantioselectivity. Furthermore, these transformations frequently occur under mild conditions, tolerate a broad array of functional groups, and proceed with high stereoselectivity. The area of catalysis is sometimes referred to as a 'foundational pillar' of green chemistry. Catalytic reactions often reduce energy requirements and decrease separations because of increased selectivity; they are also capable of permitting the use of renewable feedstocks of less toxic reagents or minimizing the quantities of reagents needed. New catalytic organic synthesis methodologies have, thus, offered several possibilities for considerable improvement in the eco-compatibility of fine chemical production. Hence, these catalytic methodologies have emerged as powerful tools for the efficient and chemoselective synthesis of heterocyclic molecules. Key Features: Presents the synthesis of different five-membered heterocycles. Contains the most up-to-date information in this fast-moving field. Covers novel catalytic approaches used in the study and application of catalysts in synthetic organic reactions. Presents new methodologies for the synthesis of heterocycles.

Aluminium, magnesium and titanium are alloys of special interest for engineering applications in a wide range of sectors such as aeronautics, automotive and medical. Their low density, along with sufficient mechanical properties, makes them especially adequate for sectors such as transportation allowing diminishing weight less fuel consumption and emissions to the atmosphere.

Advanced high strength steels (AHSSs) for auto-making are primarily produced by rolling, plus heat treatment technologies if necessary. However, due to the metallurgical complexity of AHSSs, it is impossible to roll all of the AHSS grades in a rolling mill with the same rolling technology. Each of AHSSs has unique applications in vehicles, and specified rolling technologies are required to produce high quality AHSS products where they might be the best employed to meet performance demands of the automotive parts. Such background has prompted the publication of this scholarly book in the area of rolling of AHSSs with a purpose of providing readers with a valuable technical document that can be used in the research and development of AHSSs for automotive and other manufacturing industries. With contributors from USA, Germany, Poland, Italy, Spain, Austria, Australia, China, India and Iran, the book highlights the latest advances in rolling technologies of AHSSs. It focuses on the theory, simulation and practice of the rolling of AHSSs: The book introduces the history, types and advances of AHSSs and their processes; proposes new theory that is applicable to the rolling of AHSSs, presents mathematical and numerical modelling of AHSSs in rolling; covers thermomechanical processing technologies of AHSSs; provides case studies on the rolling practice of the most popular AHSSs and includes other rolling-related technologies of AHSSs. The book will be useful for both theoretical and applied research aimed at AHSSs rolling technologies, and will be a scientific and valuable literature for the metallurgists, engineers, materials scientists, academics and graduate students who are studying and working with AHSSs and their rolling technologies worldwide.

'Great characters, fine writing, totally engrossing' STEPHEN KING It might have been the end of days. Instead it was the beginning of something shockingly new. They called the comet Cain, after the astronomer who discovered it. It passed 500,000 miles from Earth. We were spared planetary destruction and granted a light show like no other. But, one year later, Earth span into the debris field left by the comet and a meteor storm struck. Roads, buildings and even a small town were annihilated. The meteors impacted heavily around the dying mining town of Northfall, Minnesota. It was the night of a mysterious double murder, the deed overshadowed by the discovery that the burning remains of the rock contained an unknown substance more precious than gold: the Ninth Metal. And with that discovery, everything changed. Benjamin Percy is an award-winning novelist, celebrated comic books writer and author of the Wolverine podcast. The Ninth Metal is the first of a cycle of novels set in a shared universe. Praise for The Ninth Metal: 'Whether you choose to think of him as the Elmore Leonard of rural Minnesota or the Stephen King of Science Fiction, Percy - with his extraordinary and unrelenting eye - dishes up humanity like some kind of otherworldly blue plate special, at once deeply familiar and wildly new' Margaret Stohl, No. 1 New York Times Bestselling Author 'Take one part dystopia, one part sci-fi, two parts apocalypse, then ride them roughshod through a bleak and bloody western, and it still wouldn't get close to what Ben Percy does here, which is blow open the core of humanity's dark heart' Marlon James, Booker Prize winning author of Black Leopard, Red Wolf 'The Ninth Metal continues his streak of thrilling, incisive genre bending goodness. It's a sci-fi novel, a crime novel and a super-hero novel, too. Audacious and intelligent and exactly what I was dying to read' Victor LaValle, author of The Changeling

Duplex Stainless Steels (DSSs) are chromium-nickel-molybdenum-iron alloys that are usually in proportions optimized for equalizing the volume fractions of austenite and ferrite. Due to their ferritic-austenitic microstructure, they possess a higher mechanical strength and a better corrosion resistance than standard austenitic steels. This type of steel is now increasing its application and market field due to its very good properties and relatively low cost.

This book is a review of the most recent progress achieved in the last 10 years on microstructure, corrosion resistance and mechanical strength properties, as well as applications, due to the development of new grades. Special attention will be given to fatigue and fracture behavior and to proposed models to account for mechanical behavior. Each subject will be developed in chapters written by experts recognized around the international industrial and scientific communities.

The use of duplex stainless steels has grown rapidly in the last 10 years, particularly in the oil and gas industry, chemical tankers, pulp and paper as well as the chemical industry. In all these examples, topics like welding, corrosion resistance and mechanical strength properties (mainly in the fatigue domain) are crucial. Therefore, the update of welding and corrosion properties and the introduction of topics like texture effects, fatigue and fracture strength properties, and mechanical behavior modeling give this book specific focus and character.

Diffusionsvorg{nge legen Zeugnis ab von den {u erst komplizierten energetischen und strukturellen Zusammenh{ngen in Festk-rpern, welche eine fast perfekte Ordnung mit Elementen einer Fehlordnung verbinden, die f}r ihrVerhalten oft entscheidend sind. Auch wenn der Diffusion und den diffusionsgesteuerten Umwandlungen, Grenzfl{chenreaktionen und Verformungsvorg{ngen in vielen Lehr- und Fachb}chern Beachtung zuteil wird, so hat es doch seit mehr als 30 Jahren keine deutschsprachige Monographie gegeben, welche dieses wichtige Gebiet umfassend und detailliertdarstellt. Der Autor, der Jahrzehnte hindurch den einschl{gigen wissenschaftlichen Fortschritt mitgepr{gt hat, hilft nun diesem Mangel ab. Er hat ein grundlegendes Werk verfa t, das Wissenschaftlern nicht nur bei der Erforschung modernster - u.a. keramischer oder hochpolymerer - Werkstoffe oder metallischer Schmelzen, sondern auch Studenten bei Vorlesungen, Seminar und Diplomarbeit unterst}tzt.
