"Acoustic Waves: From Microdevices to Helioseismology" ed. by Marco G. Beghi
InTeOpP | 2011 | ISBN: 9533075724 9789533075723 | 665 pages | PDF | 51 MB
This book presents several aspects of the active research ongoing in the field of Acoustic Waves. Theoretical efforts are leading to a deeper understanding of phenomena, also in complicated environments like the solar surface boundary. A whole class of widespread microdevices, including filters and sensors, is based on the behaviour of acoustic waves propagating in thin layers. The search for better performances is driving to new materials for these devices, and to more refined tools for their analysis.

FREEDownload : Atomically-Precise Methods for Synthesis of Solid Catalysts

Atomically-Precise Methods for Synthesis of Solid Catalysts by Sophie Hermans and Thierry Visart de Bocarme
English | 2014 | ISBN: 1849738297 | 316 pages | PDF | 14 MB

Atomically-Precise Methods for Synthesis of Solid Catalysts
There is much interest in preparing catalysts with specific structures for a desired catalytic activity. Although there has been a great amount of research into correlating particles sizes and microstructure to catalytic activity, knowledge about practical catalysts still remain ill-defined. The current challenge is now to understand atomic control.

provides an overview of recent developments in heterogeneous catalysts preparation which aim at controlling the microstructure of such catalysts at the atomic scale. Each chapter provides a different synthetic approach to achieve atomic-scale control along techniques to characterize the atomically-precise solids. Topics covered include bimetallic supported catalysts from single-source precursors zeolite-supported molecular metal complex catalyst, surface organometallic chemistry, atomic layer deposition and electron microscopy of catalysts.

Edited by active researchers in the area, the book aims to bridge the gap between surface science and heterogeneous catalysis. The book is suitable for graduate students as well as researchers in academia in industry from various disciplines including engineering, inorganic/organometallic chemistry, surface science and physical chemistry interested in catalyst design.

Rare-Earth Implanted MOS Devices for Silicon Photonics: Microstructural, Electrical and Optoelectronic Properties

FREEDownload : Rare-Earth Implanted MOS Devices for Silicon Photonics: Microstructural, Electrical and Optoelectronic Properties

Rare-Earth Implanted MOS Devices for Silicon Photonics: Microstructural, Electrical and Optoelectronic Properties by Lars Rebohle and Wolfgang Skorupa
English | 2010-10-21 | ISBN: 3642144462 | PDF | 220 pages | 3 MB

Rare-Earth Implanted MOS Devices for Silicon Photonics: Microstructural, Electrical and Optoelectronic Properties
The book concentrates on the microstructural, electric and optoelectronic properties of rare-earth implanted MOS structures and their use as light emitters in potential applications. It describes the structural formation processes in the gate oxide during fabrication and under operation, how this microstructure development will affect the electrical device performance and how both microstructure and electrical characteristics determine the optoelectronic features of the light emitters. However, most of the discussed physical processes as well as the described fabrication methods and device characterization techniques are of general interest and are beyond the scope of this type of light emitter. The book will be of value to engineers, physicists, and scientists dealing either with Si based photonics in particular or optoelectronic device fabrication and characterization in general.

Fractal Mechanics of Polymers: Chemistry and Physics of Complex Polymeric Materials

FREEDownload : Fractal Mechanics of Polymers: Chemistry and Physics of Complex Polymeric Materials

Fractal Mechanics of Polymers: Chemistry and Physics of Complex Polymeric Materials by G. V. Kozlov, Yu G. Yanovskii
2014 | ISBN: 1771880414 | English | 384 pages | PDF | 11 MB

Fractal Mechanics of Polymers: Chemistry and Physics of Complex Polymeric Materials
This new book explores the consideration of relationships that connect the structural and basic mechanical properties of polymeric mediums within the frameworks of fractal analysis with cluster model representations attraction. Incidentally, the choice of any structural model of medium or their combinations is defined by expediency and further usage convenience only. This book presents leading-edge research in this rapidly changing and evolving field.

The book presents descriptions of the main reactions of high-molecular substances within the frameworks of fractal analysis and irreversible aggregation models. Synergetics and percolation theory were also used. In spite of the enormous number of papers dealing with the influence of the medium on the rate of chemical reactions (including synthesis of polymers), no strict quantitative theory capable of "universal" application has been put forward up until now. It is now possible to describe the relationship between the reaction rate constants and the equilibrium constants with the nature of the medium in which the reactions take place by means of a single equation. This important book for the first time gives structural and physical grounds of polymers synthesis and curing, and the fractal analysis is used for this purpose.

This new book:

* Highlights some important areas of current interest in polymer products and chemical processes

* Focuses on topics with more advanced methods

* Emphasizes precise mathematical development and actual experimental details

* Analyzes theories to formulate and prove the physicochemical principles

* Provides an up-to-date and thorough exposition of the present state of the art of complex polymeric materials

Physical Approaches to Biological Evolution

Mikhail V. Volkenstein, "Physical Approaches to Biological Evolution"
1994 | pages: 402 | ISBN: 3642787908 | DJVU | 4,5 mb

Physical Approaches to Biological Evolution
"Mr. Wolkenstein's , whether or not it proves to give the ultimate truth on the matters with which it deals, certainly deserves, by its breadth and scope and profundity, to be considered an impor­ tant event in the philosophical world." This is a quotation from an introduction written by Bertrand Russell for Ludwig Wittgenstein's Tractatus Logico-Philosophicus. I exchanged only name and subject. As for the rest, I could continue quoting Russell, but I would rather say something myself. As Wittgenstein did with formal logic, Wolkenstein rectifies our views on how to approach the logic of life from a formal theoretical basis. Many bio­ logists do not believe that their subject lends itself to the scrutiny of physical theory. They certainly admit that one can simulate biological phenomena by models that can be expressed in a mathematical form. However, they do not believe that biology can be given a theoretical foundation that is defined within the general framework of physics. Rather, they insist on a holistic approach, banning any reduction to fundamental principles subject to physical theory.

Nonlinear Waves in Elastic Crystals

Nonlinear Waves in Elastic Crystals
English | Physics, Mathematics | January 2000 | ISBN-10: 0198534841 | 320 pages | Djvu | 3.2 mb
The mathematical modelling of changing structures in materials is of increasing importance to industry where applications of the theory are found in subjects as diverse as aerospace and medicine.

Nonlinear Waves in Elastic Crystals
This book deals with aspects of the nonlinear dynamics of deformable ordered solids (known as elastic crystals) where the nonlinear effects combine or compete with each other. Physical and mathematical models are discused and computational aspects are also included. Different models are considered – on discrete as well as continuum scales – applying heat, electricity, or magnetism to the crystal structure and these are analysed using the equations of rational mechanics. In this way the student is introduced to the important equations of nonlinear science that describe shock waves, solitons and chaos and also the non-exactly integrable systems or partial differential equations. A large number of problems and examples are included, many taken from recent research and involving both one-dimensional and two-dimensional problems as well as some coupled degress of freedom.
