Supercritical fluid technology can be seen as a green and environmentally friendly alternative to conventional. Current information on these topics is spread through different publications in different peer-reviewed journals. The editors were therefore of
Active implants are actually drug or protein-eluting implants that induce healing effects, in addition to their regular task, such as support. This effect is achieved by controlled release of the active agent to the surrounding tissue. This book will give a broad overview of biomaterial platforms used as basic elements of drug-eluting implants. It will include mainly coatings for vascular stents with controlled release of antiproliferative agents, wound dressings with controlled release of antibacterial agents, drug-eluting vascular grafts, protein-eluting scaffolds for tissue regeneration, drug-eluting platforms for dental and other applications. Thus, both internal and external implants ar...
Supercritical Fluid Technology for Energy and Environmental Applications covers the fundamental principles involved in the preparation and characterization of supercritical fluids (SCFs) used in the energy production and other environmental applications. Energy production from diversified resources — including renewable materials — using clean processes can be accomplished using technologies like SCFs. This book is focused on critical issues scientists and engineers face in applying SCFs to energy production and environmental protection, the innovative solutions they have found, and the challenges they need to overcome. The book also covers the basics of sub- and supercritical fluids, li...
This book is a comprehensive treatise on the current status of nematology in South Asia, covering major field problems and their solutions through “nematode-crop-region” modules conducted in the region by renowned experts, and the emerging scenario of nematode problems and the development of new management technologies. It includes the practical field experiences of renowned experts, supported by original images. The book will be of particular interest to plant protection and extension workers, undergraduate and postgraduate students, researchers, and those involved with the pesticide industry. It will also serve as a handbook for students preparing for competitive examinations.
Esta obra apresenta contribuições que cobrem o estado-da-arte de vários tópicos científicos e técnicos e que foram desenvolvidos no âmbito das actividades científicas e de formação de um projecto-em-rede CYTED, intitulado RIMADEL - Rede Ibero-Americana de Nuevos Materiales para el Diseño de Sistemas Avanzados de Liberación de Fármacos en Enfermidades de Alto Impacto Socioeconómico. Este projecto pretendeu criar uma plataforma Ibero-Americana de intercâmbio de investigadores, de conhecimento e de recursos científicos e tecnológicos, orientada para o desenvolvimento de novos biomateriais com aplicações em sistemas avançados de libertação de agentes terapêuticos, e em sup...
Nanotechnology offers great potential to revolutionize conventional food science and the food industry. The use of nanotechnology in the food industry promises improved taste, flavor, color, texture, and consistency of foodstuffs and increased absorption and bioavailability of nutraceuticals. Food Nanotechnology: Principles and Applications examines the current state of nanoscale phenomena and processes, benefits and risks of nanotechnology. This work contains 18 chapters particularly focused on the design, production, and utilization of nanoparticles, with specific applications for the food industry. Through several studies, it has been proven that nanotechnology can offer distinct advantag...
José Tomás de Sousa Martins, nascido em 1843 em Alhandra (Vila Franca de Xira), marca a medicina e a sociedade portuguesa da segunda metade do século XIX. Médico e professor de Medicina, orador brilhante dotado de humor e inteligência, homem de atividade inesgotável e praticante incansável da caridade aos mais desfavorecidos, exerce forte influência nos colegas de profissão, nos alunos, nos pacientes... Esta influência desenvolve-se, transforma-se e ultrapassa os grilhões do tempo. A figura de Sousa Martins é modelada, assumindo contornos de santo laico, num culto atual, visível no Campo dos Mártires, em Lisboa, em torno da sua estátua, e no cemitério de Alhandra, onde está ...
O livro "Química de Polímeros" resultou de uma necessidade, há muito sentida, de apresentar, num livro de texto, o desenvolvimento que a química polimérica possui em Portugal. Este campo, ausente de livros portugueses, embora não diminuísse o reconhecimento, impacto e grande qualidade da área em Portugal, parecia não relevar a sua projeção interna (e quiçá externa). O livro, lançado por ocasião do XIX Encontro da Sociedade Portuguesa de Química, que decorreu nos passados dias 15-17 de Abril de 2004, tem, a ajuizar pela recetividade mostrada, sucesso garantido. Este livro resulta da contribuição de 68 cientistas, nas sua grande maioria portugueses, de reconhecido mérito na ...
