Better Looking, Better Living, Better Loving: How Chemistry can Help You Achieve Life's Goals - PDF
نویسندگان: خلاصه: John Emsley has carved out quite a niche for himself in writing popular books (not textbooks) dedicated to scientific matters in general, and chemistry matters in particular. One of his more inspired titles is "Better Looking, Better Living, Better Loving", which has a very unfortunate subtitle "How Chemistry Can Help You Achieve Life's Goals". The subtitle makes the book sound like a how-to book (Make your own mascara! Better breath through home-made mouthwash!) It is NOT a how-to book, but rather a how-it-is-done book. In a wide-ranging series of short essays, Emsley covers most consumer topics that exist at the intersection of chemistry and the personal consumer, including food, plastic containers, cosmetics, pharmaceuticals, birth control, cleaning products (for humans, clothes, and dishes), etc.The beauty of this book is that it can be picked up and read starting anywhere, and is therefore an ideal bathroom book (especially since there are a lot of bathroom-related topics!) or coffee table book (again, since there are a lot of food topics!). This makes some of the topics a little repetative for someone reading the book cover-to-cover over the course of a few days or weeks, but it's a better choice for a book of this type. I think the science is readily understandable to the average person (although it might be hard for me to judge, being a chemistry teacher), and there is a glossary for more scientific terms and broadened explanations. More importantly, the science is correct and rigorous while still presented in a palatable manner.I think North American readers will notice the no-nonsense style of writing. British authors (at least, scientific ones) tend to be more forthright than their American cousins, and it's especially noticable in this book's discussions on abortion and rape - two topics that American authors would couch in more subtle terms, with at least an acknowledgement of the cultural/moral issues associated with them. Similarly, most Americans are used to hedging their bets: Emsley comes right out and tells people that they are wrong to believe that aluminum has anything to do with Alzheimers, for example, and debunks other "common knowledge" associations just as ruthlessly, if they been scientifically demonstrated to be wrong.In terms of sheer readability, I think I prefer Joe Schwarcz's books that cover similar terrain. However, Emsley's book is more focussed and logically presented. It's certainly interesting, certainly entertaining, and even the best-read chemist is likely to learn something s/he didn't know. Unfortunately, the price is excessive compared to other books of this type (even other Emsley titles) - what gives, Amazon?
High temperature strain of metals and alloys: physical fundamentals - Original PDF
نویسندگان: خلاصه: Creep and fatigue are the most prevalent causes of rupture in superalloys, which are important materials for industrial usage, e.g. in engines and turbine blades in aerospace or in energy producing industries. As temperature increases, atom mobility becomes appreciable, affecting a number of metal and alloy properties. It is thus vital to find new characterization methods that allow an understanding of the fundamental physics of creep in these materials as well as in pure metals. Here, the author shows how new in situ X-ray investigations and transmission electron microscope studies lead to novel explanations of high-temperature deformation and creep in pure metals, solid solutions and superalloys. This unique approach is the first to find unequivocal and quantitative expressions for the macroscopic deformation rate by means of three groups of parameters: substructural characteristics, physical material constants and external conditions. Creep strength of the studied up-to-date single crystal superalloys is greatly increased over conventional polycrystalline superalloys. From the contents: - Macroscopic characteristics of strain at high temperatures - Experimental equipment and technique of in situ X-ray investigations - Experimental data and structural parameters in deformed metals - Subboundaries as dislocation sources and obstacles - The physical mechanism of creep and the quantitative structural model - Simulation of the parameters evolution - System of differential equations - High-temperature deformation of industrial superalloys - Single crystals of superalloys - Effect of composition, orientation and temperature on properties - Creep of some refractory metals For materials scientists, solid state physicists, solid state chemists, researchers and practitioners from industry sectors including metallurgical, mechanical, chemical and structural engineers.
The Iron Oxides Structure, Properties, Reactions, Occurences and Uses - Original PDF
نویسندگان: خلاصه: Preface to the Second Edition Since this book first appeared, there have been hundreds of new publications on the subject of iron oxides. These have covered a wide range of disciplines including sur- face chemistry, the geosciences, mineralogy, environmental science and various branches of technology. In view of the amount of new material that is available, we decided, that once the copies of the first edition were exhausted, we would prepare a second edition that would incorporate the new developments. As before, our aim has been to bring all aspects of the information concerning iron oxides into a single, compact volume. All the chapters have been revised and up- dated and new figures and tables added. The book is structured according to topic with the same arrangement as in the first edition being followed. In view of the re- cent recognition of the impact iron oxides have on environmental processes, a chap- ter dealing with the environmental aspects of these compounds has been added. The book concludes with a considerably expanded bibliography. We hope that this new edition will continue to be of interest to all those research- ers who, in one way or another, are involved with iron oxides. Numerous persons and institutions from around the world again supplied data, figures, colour pictures and electron micrographs and technical help. These include Dr. H. Chr. Bartscherer (Mçnchen), Mr M. Burlot (Apt), Dr. R. Båumler and Dr. Be- cher (Freising), Mr H. Breuning (Stuttgart), Dr. J. M. Bigham (Columbus, USA), Dr. G. Buxbaum (Bayer), Dr. L.

Iron Oxides by Damien Faivre - PDF
نویسندگان: خلاصه: As the name of the book “Iron oxides: from nature to applications” suggests, iron oxides are not only widespread in the environment, but also widely used by mankind in a variety of applications (Figure 1.1). Both this ubiquitous presence in nature and the utilization as tools have been established for cen- turies and are still valid today. The first illustrative examples of iron oxides certainly are compass needle or rust (Figure 1.2). Iron oxides are present in solid, liquid, and gaseous environments, with respective examples such as rocks, as mineral inclusion in swimming bacteria or in aerosols. Depending on the type of use, several sources of iron oxides exist. Applications range from the heavy steel production to medicine and art. The different aspects of mineral formation and their use as well as modern characterization techniques are reviewed in this book
Synthetic Metal Containing Polymers - Original PDF
نویسندگان: خلاصه: The development of the field of synthetic metal-containing polymers - where metal atoms form an integral part of the main chain or side group structure of a polymer - aims to create new materials which combine the processability of organic polymers with the physical or chemical characteristics associated with the metallic element or complex. This book covers the major developments in the synthesis, properties, and applications of synthetic metal-containing macromolecules, and includes chapters on the preparation and characterization of metal-containing polymers, metallocene-based polymers, rigid-rod organometallic polymers, coordination polymers, polymers containing main group metals, and also covers dendritic and supramolecular systems. The book describes both polymeric materials with metals in the main chain or side group structure and covers the literature up to the end of 2002.![Quantum Mechanics, Volume 3: Fermions, Bosons, Photons, Correlations, and Entanglement (2nd Edition) [2019] - Original PDF](https://dl.libsan.ir/images/1/12/Quantum Mechanics, Volume 3_5edf205fe0f9f.jpg)
