Chemical Composition And Structure of Materials

Nanoporous materials are critical to various fields of research, including ion exchange, separation, catalysis, sensor applications, biological molecular isolation, and purification. In addition, they offer new opportunities in such areas as inclusion chemistry, guest-host synthesis, and molecular manipulations and reactions at the nanoscale.

The aim of this book is to provide an overview on the importance of stoichiometry in the materials science field. It presents a collection of selected research articles and reviews providing up-to-date information related to stoichiometry at various levels. Though specifically addressed to readers with a background in physical science, this book will be of interest to researchers working in materials science, engineering and technology.

In this book we explore new approaches to understanding the physical and chemical properties of emergent complex functional materials, revealing a close relationship between their structures and properties at the molecular level.

This book, edited by Potyrailo and Amis, addresses a new paradigm-shifting approach in the search for new materials-Combinatorial Materials Science. One way to consider such an approach is to imagine an adventurous chef who decides to look for new entrees by cooking food ingredients in many pots using different combinations in every pot, and boil­ ing, steaming, or frying them in various ways. Although most of the pots will not have the tastiest food ever devised, some recipes will taste intriguing, and some eventually will lead to a discovery of a new fascinating cuisine. Of course, having a skilled chef design the com­ binatorial formulation will certainly be helpful in ensuring a successful outcome. Similar to food, each engineering material is a complex product of its chemical composition, structure, and processing. Generally, each of these components matters–-change one and you get another material. Most of these "new" materials will be less good than ones we use now since existing materials have been refined with the extensive work of scientists and engi­ neers. At the same time if one prepares diverse materials like our adventurous chef, chang­ ing material composition, processing conditions and time, etc. , some of these materials will be superior to existing ones and a few might represent breakout technology.

Supplementary cementing materials (SCMs), such as fly ash, slag, silica fume, and natural pozzolans, make a significant difference to the properties of concrete but are rarely understood in any detail. SCMs can influence the mechanical properties of concrete and improve its durability in aggressive environments.
