Optical properties, particularly in the infrared range of wavelengths, continue to be of enormous interest to both material scientists and device engineers. The need for the development of standards for data of optical properties in the infrared range of wavelengths is very timely considering the on-going transition of nano-technology from fundamental R&D to manufacturing. Radiative properties play a critical role in the processing, process control and manufacturing of semiconductor materials, devices, circuits and systems. The design and implementation of real-time process control methods in manufacturing requires the knowledge of the radiative properties of materials. Sensors and imagers operate on the basis of the radiative properties of materials. This book reviews the optical properties of various semiconductors in the infrared range of wavelengths. Theoretical and experimental studies of the radiative properties of semiconductors are presented. Previous studies, potential applications and future developments are outlined. In Chapter 1, an introduction to the radiative properties is presented. Examples of instrumentation for measurements of the radiative properties is described in Chapter 2. In Chapters 3-11, case studies of the radiative properties of several semiconductors are elucidated. The modeling and applications of these properties are explained in Chapters 12 and 13, respectively. In Chapter 14, examples of the global infrastructure for these measurements are illustrated.

Driving evolution forward, the Earth's physical environment has challenged the very survival of organisms and ecosystems throughout the ages. With a fresh new perspective, Evolution on Planet Earth shows how these physical realities and hurdles shaped the primary phases of life on the planet. The book's thorough coverage also includes chapters on more proximate factors and paleoenvironmental events that influenced the diversity of life. A team of notable ecologists, evolutionary biologists, and paleontologists join forces to describe drifting continents, extinction events, and climate change -- important topics that continue to shape Earth's inhabitants to this very day. In a world where global change has become an international issue, this book provides a several billion-year evolutionary perspective on what the environment and environmental change means to life.* Provides thorough background information on each topic while introducing cutting-edge research* Features original material solicited from the leading minds in evolutionary biology and geology today* Emphasizes the influence of massive geological forces - continental drift, volcanic activity, sea and tides

This book is part of a series on sustainability. Specifically, it deals with the issue of sustainable water use. Fresh sources of potable water are being depleted across the world. Pure water is the goal of water utilities as well as several industries. Well past the experimental stage, membrane processes are now a proven and reliable method of providing high-quality, cost-effective water. Membrane technologies have immediate applications to treatment of fresh, brackish and sea waters, as well as wastewater reclamation. With innovative module design and engineering, micro- and ultra-filtrations have become effective and economical for drinking water production, particularly for removal of microorganisms. Membrane bioreactors are being developed for municipal and industrial water recycling. Various membrane processes are also used to remove contaminants from industrial wastewaters.This book covers the fundamental and practical concepts and issues regarding the application of membrane technologies for sustainable water treatment. It describes and compares the effectiveness of desalination versus water recycling for long-term sustainable water use. - Describes the global water situation with respect to sustainability - Emphasizes the role of membrane technologies - Compares the strategies of water recycling and desalination
