Atomic Mechanics of Solids
Author: A.K. Macpherson
Publisher: Elsevier
ISBN: 0444600345
Category : Science
Languages : en
Pages : 224
Book Description
This volume brings together some of the presently available theoretical techniques which will be useful in the design of solid-state materials. At present, it is impossible to specify the atomic composition of a material and its macroscopic physical properties. However, the future possibilities for such a science are being laid today. This is coming about due to the development of fast, cheap computers which will be able to undertake the calculations which are necessary.Since this field of science is fairly new, it is not yet quite clear which direction of analysis will eventually prove to be the most successful. In this respect the author has included the most relevant promising subject areas, based on seven years of research experience in the field. An extensive literature already exists for most of the areas covered here, thus when more detailed analysis can be found elsewhere, the assumptions made are discussed, and only an outline of the method involved is presented. Comprehensive indexes are provided to assist the reader in further studies. This is a potentially important field which is slowly getting underway and only needs a significant development to attract a broader scientific interest. The work will be of considerable interest to program managers needing to assess this new field.

Evolution's Destiny
Author: R J P Williams
Publisher: Royal Society of Chemistry
ISBN: 184973559X
Category : Science
Languages : en
Pages : 344
Book Description
This book is written as an addition to Darwin's work and that of molecular biologists on evolution so as to include views of it from the point of view of chemistry rather than just from our knowledge of the biology and genes of organisms. By concentrating on a wide range of chemical elements, not just those in traditional organic compounds, we show that there is a close relationship between the geological or environmental chemical changes from the formation of Earth and those of organisms from the time of their origin. These are considerations which Darwin or other scientists could not have explored until very recent times since sufficient analytical data were not available. They lead us to suggest that there is a combined geo- and bio-chemical evolution, that of an ecosystem, which has had a systematic chemical development. In this development the arrival of new very similar species is shown to be by random Darwinian competitive selection processes such that a huge variety of species coexist with only minor differences in chemistry and advantages. This is in agreement with previous studies. On the large scale of evolution of very different organisms, and over greater timescales, by way of contrast, we observe that groups of species have special, different, chemical features and function. It is more difficult to understand how they evolved and therefore we examine their chemical development in detail. Overall there is a cooperative evolution of a chemical system driven by capture of energy, mainly from the sun, and its degradation in which the chemistry of both the environment and organisms are facilitating intermediates. We shall suggest that the overall drive of the whole joint system is to optimise the rate of this energy degradation. Since the environmental changes are inorganic and relatively fast they move inevitably to equilibrium. The living part of the system, the organisms, under the influence of this inevitable environmental change are forced to follow but as they are increasingly energised and their reactions are slow, they move further away from equilibrium. We are able to explore the ways in which this chemical system evolved, recognising that as complexity of the chemistry of organisms increased, they had to be formed from more and more compartments and to become part of a chemically cooperative overall activity. They could not remain as isolated species. Only in the last chapter do we attempt to make a connection between the changing chemistry of organisms with the coded molecules of each cell which have to exist to explain reproduction.

Publisher: Royal Society of Chemistry
ISBN: 1782625828
Category : Technology & Engineering
Languages : en
Pages : 293
Book Description
Chemically-modified carbon nanotubes (CNTs) exhibit a wide range of physical and chemical properties which makes them an attractive starting material for the preparation of super-strong and highly-conductive fibres and films. Much information is available across the primary literature, making it difficult to obtain an overall picture of the state-of-the-art. This volume brings together some of the leading researchers in the field from across the globe to present the potential these materials have, not only in developing and characterising novel materials but also the devices which can be fabricated from them. Topics featured in the book include Raman characterisation, industrial polymer materials, actuators and sensors and polymer reinforcement, with chapters prepared by highly-cited authors from across the globe. A valuable handbook for any academic or industrial laboratory, this book will appeal to newcomers to the field and established researchers alike.

Category : Science
Languages : en
Pages : 279
Book Description
This book gives an overview of the research field of artificial cilia, a novel technology for controlling and sensing fluid flow at microscopic scales. This field is inspired by nature, namely by naturally occurring cilia which are tiny hairs covering biological cells and that are used already for over a billion years by nature to generate and sense fluid flow. The research field started less than a decade ago and has grown fast in recent years, since it offers very interesting options for flow control in lab-on-a-chip devices.

Nanoporous Gold
Author: Arne Wittstock
Publisher: Royal Society of Chemistry
ISBN: 184973528X
Category : Technology & Engineering
Languages : en
Pages : 265
Book Description
High-surface-area materials have recently attracted significant interest due to potential applications in various fields such as electrochemistry and catalysis, gas-phase catalysis, optics, sensors and actuators, energy harvesting and storage. In contrast to classical materials the properties of high-surface-area materials are no longer determined by their bulk, but by their nanoscale architecture. Nanoporous gold (np-Au) represents the fascinating class of mesoporous metals that have been intensively investigated in recent years. The current interest and the increasing number of scientific publications show that np-Au by itself is an outstanding nano-material that justifies a book devoted to all aspects of its properties and applications. The resulting publication is a discussion of this unique nano-material and is an accessible and comprehensive introduction to the field. The book provides a broad, multi-disciplinary platform to learn more about the properties of nanoporous gold from an inter-disciplinary perspective. It starts with an introduction and overview of state-of-the-art applications and techniques characterizing this material and its applications. It then covers the progress in research within the last years. The chapters are in-depth overviews written by the world's leading scientists in the particular field. Each chapter covers one technique or application so that the reader can easily target their favoured topic and will get the latest and state-of-the-art information in the field.
