The discovery of multiwalled carbon nanotubes(CNTs) in 1991 and the subsequent discovery of single-walled CNTs in 1993 have led to a worldwide excitement to explore their fundamental properties and potential device applications. A sing- walled CNT is structurally a sheet of graphene rolled into a seamless tube, which possesses a diameter of the order of a nanometer but a length thousands of times greater. The large aspect ratio and small cross section size make it nearly an ideal, quasi-one-dimensionalsystem, which has provided a concrete context for chemists, physicists,andengineersto collaborativelyworktogetherin the?eld ofnanoscience and nanotechnology. As a result of such efforts in the last two decades, superior electrical, optical, and mechanical properties of CNTs have been theoretically p- dicted and experimentally demonstrated. The unique material properties of CNTs have made it interesting for a variety of applications. For example, depending on the orientation of its graphene lattice relative to the nanotube axis, the CNT can be either metallic or semiconducting. This property makes the material interesting for developing not only nanoscale semiconductor devices but also a new interc- nect technologyto competewith the state-of-theart copperinterconnecttechnology. The property has also imposed yet-solved challenges in the ?eld. For example, one of the major challenges that holds CNTs back from electronic application is how to produce pure all-semiconducting CNTs, based on which a device that can be effectively turned off can be built.

This book discusses the theoretical foundations of the structural modeling method applied to metamaterials. This method takes into account the parameters of the crystal lattice, the size of the medium particles, as well as their shape and constants of force interactions between them. It provides mathematical models of metamaterials that offer insights into the qualitative influence of the local structure on the effective elastic moduli of the considered medium and into performing theoretical estimations of these quantities. This book is useful for researchers working in the fields of solid mechanics, physical acoustics, and condensed matter physics, as well as for graduate and postgraduate students studying mathematical modeling methods.
This book was conceived from a simple question as to why cancer is so difficult to treat. Ultimately we want to find ways to cure cancers, but that may be an elusive dream at least with the technologies we have now and expect to have in the near future. This leads the question of whether it is possible to improve current cancer treatment methods, especially from the perspective of enhancing targeted drug delivery to tumors. This volume is designed to provide information related to the difficulties in treating cancers through targeted drug delivery, our current understanding of cancer biology, and potential technologies that might be used to achieve enhanced drug delivery to tumors. An ideal drug delivery system for treating cancers would maximize the therapeutic efficacy with minimal side effects in clinical applications. The seemingly improved anticancer efficacy of the current nanoparticle-based formulations needs to be viewed from the context of very poor success rates for translation to human applications. The results of in vitro cell culture models and small animal in vivo experiments have not been extrapolated to clinical applications. Finding the reasons for the lack of successful translation is required if we are to discover approaches to substantially extend the survival time of cancer patients, and hopefully identify cures. Cancer Targeted Drug Delivery: Elusive Dream describes some answers of achieving the so far elusive dream of treating cancers like other chronic diseases with therapies that focus using improved drug delivery systems designed to better align with the unique biological and physiological properties of cancer.
Development of new-generation vaccines is now more challenging than ever, as identifying, purifying and evaluating vaccine antigens is a complex undertaking. Most importantly, once the relevant antigens have been identified, key focus then shifts to the development of suitable delivery systems and formulations to achieve maximum in vivo potency with minimum potential side effects. These novel formulations-many of which will be nanoparticulates-can deliver the antigens to the desired site, to the relevant antigen presenting cells, and prevent systemic exposure of the immune potentiators. The proposed book will outline all the critical steps that need to be considered for successful development of various types of nanoparticulate delivery systems for vaccine antigens. These contributions from leading experts in the area of vaccine formulation and delivery systems will tie in what is the most current status, including clinical evaluations with these novel vaccine technologies.

The decision to invest in oil field development is an extremely complex problem, even in the absence of uncertainty, due to the great number of technological alternatives that may be used, to the dynamic complexity of oil reservoirs - which involves mul- phase flows (oil, gas and water) in porous media with phase change, and to the c- plicated combinatorial optimization problem of choosing the optimal oil well network, that is, choosing the number and types of wells (horizontal, vertical, directional, m- tilateral) required for draining oil from a field with a view to maximizing its economic value. This problem becomes even more difficult when technical uncertainty and e- nomic uncertainty are considered. The former are uncertainties regarding the existence, volume and quality of a reservoir and may encourage an investment in information before the field is developed, in order to reduce these uncertainties and thus optimize the heavy investments required for developing the reservoir. The economic or market uncertainties are associated with the general movements of the economy, such as oil prices, gas demand, exchange rates, etc. , and may lead decision-makers to defer - vestments and wait for better market conditions. Choosing the optimal investment moment under uncertainty is a complex problem which traditionally involves dynamic programming tools and other techniques that are used by the real options theory.

This book is aimed for students, researchers and engineers searching for methodologies to obtain and characterize nanostructures in details.
Open dating plays a vital role in the distribution of the food
products from the farm or place of manufacturing to the consumer's
home. One principle is that the shelf life is a function of the
distribution conditions and can be looked at as the percentage of
consumers a manufacturer is willing to displease. Thus, one purpose
of an open date is to give consumers enough time to purchase a food
product and store it at home for a reasonable period of time before
the product reaches the end of shelf-life in terms of some degree
of quality change that is still acceptable. If products are not stored or rotated properly in distribution, then older products or those of lesser quality and perhaps compromised safety because of abuse during distribution chain and causing loss of confidence in the food category. Presently, the lack of uniformity among manufacturers and across state borders has made the practice of open dating confusing and misleading for consumers, retailers and the government. This book addresses these issues, and provides scientific and legal background to both evaluate and influence federally-regulated open-dating legislation in this country
Properties of chemical compounds and their mixtures are needed in
almost every aspect of process and product design. When the use of
experimental data is not possible, one of the most widely used
options in the use of property estimation models.
This book provides an introduction to the unique and fascinating properties of alloys and composites from novel commercialized thermosetting resins based on polybenzoxazines. Their outstanding properties such as processability, thermal, mechanical, electrical properties as well as ballistic impact properties of polybenzoxazine alloys and composites make them attractive for various applications in electronic packaging encapsulation, light weight ballistic armour composites and bipolar plate in fuel cells.
Composites have many engineering advantages over traditional materials, including increased strength, lightness, chemical resistance, and more, making them ideal for use in high performance components in a range of applications from aerospace to construction, and medicine to consumer goods. However, the use of composites also drastically increases material and processing costs. Multi-functionality combines multiple properties - such as thermal stability or electrical conductivity - into a single material to make it suitable for use in applications for which normally two or more materials would be required. By embedding a material with lightweight circuitry, for example, you can eliminate support chassis, enclosures, brackets and insulation materials not only saving weight and volume, but eliminating design and production costs for every part no longer needed. Multi-functionality also allows for smart materials, including self-healing material, shape-memory polymers and piezoelectric materials. Bringing together contributions from experts in the field of multifunctionality, this book presents the state-of-the-art in this exciting and rapidly developing field. It enables engineers and materials scientists to achieve multi-functionality in their own products, using different types of polymer matrices and various nano- and micro-sized fillers and reinforcements, including but not limited to carbon nanotubes and graphene. The latest developments in a wide range of applications,
including automotive/aerospace, electronics, construction and
medicine are covered, and future trends are also discussed, making
this book an essential reference for any researcher or engineer
hoping to stay ahead of the curve in this high-potential area
Handbook of Food Fortification and Health: From Concepts to Public Health Applications Volume 1 represents a multidisciplinary approach to food fortification. This book aims to disseminate important material pertaining to the fortification of foods from strategic initiatives to public health applications. Optimal nutritional intake is an essential component of health and wellbeing. Unfortunately situations arise on a local or national scale when nutrient supply or intake is deemed to be suboptimal. As a consequence, ill health occurs affecting individual organs or causing premature death. In terms of public health, malnutrition due to micronutrient deficiency can be quite profound imposing economic and social burdens on individuals and whole communities. This comprehensive text examines the broad spectrum of food fortification in all its manifestations. Coverage includes sections on definitions of fortifications, fortified foods, beverages and nutrients, fortifications with micronutrients, biofortification, impact on individuals, public health concepts and issues, and selective methods and food chemistry. Handbook of Food Fortification and Health: From Concepts to Public Health Applications Volume 1 is an indispensable text designed for nutritionists, dietitians, clinicians and health related professionals.
Volume 2 of the updated and extended 3rd edition of this work focuses on the chemistry and technology of rigid polyurethanes. Recent developments in obtaining polyols from renewable resources and the field of rigid polyurethanes have been included. This book is of interest to chemists and engineers in industry and academia as well as anyone working with polyols for the manufacture of PUs.
Water is essential for life, a strategic resource for every country and population. Its availability and sanitary safety is highly connected with the health and economy status of population. Burden of disease due to polluted water is a major public health problem throughout the world. Many pollutants in water streams have been identified as toxic and harmful to the environment and human health, and among them arsenic, mercury and cadmium are considered as high priority ones. Providing population with safe drinking water became the priority and at the same time a big challenge for the modern society. Many funding agencies in various countries have assigned a high priority to the envir- mental security and pollution prevention. UN, being one of them, launched the "International Decade for Action: Water for life 2005-2015. " Therefore, today's political and social climate presents an important opportunity to implement principles of sustainable development and to preserve resources essential for future life. This process requires interdisciplinary approach; it is critically important to stimulate interactions between medical doctors, chemists, physicist, materials scientists, engineers and policy makers, which are already experienced in their specific areas. It is also our ethical obligation to preserve existing water resources and existing eco systems enhancing their biodiversity. The NATO Advanced Research Workshop "Water Treatment Te- nologies for the Removal of High-Toxicity Pollutants" took place on September 13-17, 2008 in Ko ice, Slovak Republic." |
