  • In the last decade, we have witnessed a rapid growth in research and development of nanotechnology, especially nanostructured materials. Nanoporous materials as an important class of nanostructured materials possess high specific surface area, large pore volume, uniform pore size, and rich surface chemistry. These materials present great promises and opportunities for a new generation of functional materials with improved and tailorable properties for applications in adsorption, membranes, sensors, energy storage, catalysis and photocatalysis, and biotechnology, etc.

  • Enzymes are proteins that catalyze chemical reactions. A protein is simply a polypeptide composed of amino acids linked by a peptide bond, and the term generally, but not always, refers to the folded conformation. To understand how an enzyme functions, including its binding and functional properties, it is necessary to know the properties of the amino acids and how the amino acids are linked together, including the torsion angles of the bonds and the space occupied, and the interactions of the atoms leading to the final conformations of the folded protein.

  • With the rapid development of nanoscience and nanotechnology over the last decades, great progress has been made not only in the preparation and characterization of nanomaterials, but also in their functional applications. As an important one- dimensional nanomaterial, nanofibers have extremely high specific surface area because of their small diameters, and nanofiber membranes are highly porous with excellent pore interconnectivity.

  • This book focuses on the Fourier transform applications in the analysis of some types of materials. The field of Fourier transform has seen explosive growth during the past decades, as phenomenal advances both in research and application have been made. During the preparation of this book, we found that almost all the textbooks on materials analysis have a section devoted to the Fourier transform theory. Most of those describe some formulas and algorithms, but one can easily be lost in seemingly incomprehensible mathematics....

  • Until relatively recent times, most periods of technological development have been linked to changes in the use of materials (eg the stone, bronze and iron ages). In more recent years the driving force for technological change in many respects has shifted towards information technology. This is amply illustrated by the way the humble microprocessor has built intelligence into everyday domestic appliances.

  • Advanced Topics in Biomineralization is a compendium of current topics focusing on processes of formation, organization, as well as mineralization of novel structural materials. From enchondral ossification to the application of biomineralized cement, the subject of biomineralization encompasses a range of diverse disciplines including molecular biology, supramolecular chemistry, materials science and engineering. A common theme in all these areas of research in biomineralization is the ability to utilize strategies from Nature to create functional materials.

  • The possible impact of nanomaterials on future products and services is enormous. This has led to a tremendous expansion in research and development efforts related to nanoscale materials and devices. It has also raised new questions as to how these products will influence the environment, human health, business, education, and other areas of society. As with any emerging field, a vast amount of disconnected information is emerging, often spread across multiple disciplines.

  • In later eras, new materials have been closely associated with radical change. The development of paper was as important as the printing press in revolutionising communications. The introduction of gunpowder into Europe transformed warfare. In more modern times, gas lighting only became demonstrably superior to oil and candles with the introduction of the gas mantle, composed of novel materials such as thorium and cerium oxides. A hundred years ago electric filament lamps were made possible by other novel and fairly unusual materials, osmium and tungsten.

  • Just as human operators must be protected from extreme environments, so must the electronics that operate and control a functional system. When the environment proves too warm, the electronics must be insulated, refrigerated, or simply moved to cooler locations. This last option is sometimes very difficult, or impossible, and the perceived fragility of electronics must then be reconsidered. Vacuum-tube technology provides a historical example of this process.

  • Faster incorporation of new technologies into complex products and systems holds the possibility of ever-increasing advantages in cost, performance, durability, and new functionalities. A general perception on the part of many investigators is that incorporation of change is more difficult, expensive, and slow than it need be. The management of change in complex products and systems, however, does require an understanding of the significance of those changes as well as their consequences in terms of product performance and safety.
