Although supercritial fluid (SCF) technology is now widely used in extraction and purification processes (in the petrochemical, food and pharmaceuticals industries), this book is the first to address the new application of cleaning. The objective is to provide a roadmap for readers who want to know whether SCF technology can meet their own processing and cleaning needs. It is particularly helpful to those striving to balance the requirements for a clean product and a clean environment. The interdisciplinary subject matter will appeal to scientists and engineers in all specialties ranging from materials and polymer sciences to chemistry and physics. It is also useful to those developing new processes for other applications, and references given at the end of each chapter provide links to the wider body of SCF literature. The book is organized with topics progressing from the fundamental nature of the supercritical state, through process conditions and materials interactions, to economic considerations. Practical examples are included to show how the technology has been successfully applied. The first four chapters consider principles governing SCF processing, detailing issues such as solubility, design for cleanability, and the dynamics of particle removal. The next three chapters discuss surfactants and microemulsions, SCF interaction with polymers, and the use of supercritical carbon dioxide (CO2) as a cleaning solvent. The closing chapters focus on more practical considerations such as scaleup, equipment costs, and financial analysis.

As our consciousness of microbes increases, it appears that our desire to control our interactions with germs also increases in proportion. This is clearly demonstrated by examining the incredible growth in the number and sales volume of consumer products with antimicrobial claims. In the medical field as well, there is much interest in the use of antimicrobial/anti-infective materials for medical devices and general healthcare applications.Antimicrobial/Anti-Infective Materials: Principles, Applications and Devices represents the best current research and practice on ways to reduce infection caused by devices inserted into the human body. This volume presents important recent developments in the research, development, and applications of anti-infective materials for use in medical devices. It includes 15 in-depth reports by more than 40 leading specialists in biomaterials and medical devices that cover a wide range of important advances in various materials and applications. These include improved coatings and surface modifications techniques, improved materials designed for inherent infection resistance, and applications in the areas of cardiac, orthopedic, ENT, and vascular devices.This book serves the information needs of all those involved in the research, development, design, and selection of biomaterials and medical devices. It will benefit anyone who designs, uses, and monitors anti-infective materials, as well as those who develop and apply products made from these materials.
