Encapsulation Nanotechnologies

by Vikas Mittal

This unique and comprehensive book covers all the recent physical, chemical, and mechanical advancements in encapsulation nanotechnologies.Encapsulation is prevalent in the evolutionary processes of nature, where nature protects the materials from the environment by engulfing them in a suitable shell. These natural processes are well known and have been adopted and applied in the pharmaceutical, food, agricultural, and cosmetics industries.In recent years, because of the increased understanding of the material properties and behaviors at nanoscale, research in the encapsulation field has also moved to the generation of nanocapsules, nanocontainers, and other nano devices. One such example is the generation of self-healing nanocontainers holding corrosion inhibitors that can be used in anti-corrosion coatings. The processes used to generate such capsules have also undergone significant developments. Various technologies based on chemical, physical, and physico-chemical synthesis methods have been developed and applied successfully to generate encapsulated materials.Because of the increasing potential and value of the new nanotechnologies and products being used in a large number of commercial processes, the need for compiling one comprehensive volume comprising the recent technological advancements is also correspondingly timely and significant. This volume not only introduces the subject of encapsulation and nanotechnologies to scientists new to the field, but also serves as a reference for experts already working in this area.Encapsulation Nanotechnologies details in part:The copper encapsulation of carbon nanotubesVarious aspects of the application of fluid-bed technology for the coating and encapsulation processesThe use of the electrospinning technique for encapsulationThe concept of microencapsulation by interfacial polymerizationOverviews of encapsulation technologies for organic thin-film transistors (OTFTs), polymer capsule technology, the use of supercritical fluids (such as carbon dioxide), iCVD process for large-scale applications in hybrid gas barriersReadershipEncapsulation Nanotechnologiesis of prime interest to a wide range of materials scientists and engineers, both in industry and academia.

Encapsulation Technologies for Active Food Ingredients and Food Processing

by N. J. Zuidam Viktor Nedovic

Consumers prefer food products that are tasty, healthy, and convenient. Encapsulation is an important way to meet these demands by delivering food ingredients at the right time and right place. For example, encapsulates may allow flavor retention, mask bad tasting or bad smelling components, stabilize food ingredients, and increase their bioavailability. Encapsulation may also be used to immobilize cells or enzymes in the production of food materials or products, such as fermentation or metabolite production. This book provides a detailed overview of the encapsulation technologies available for use in food products, food processing, and food production. The book aims to inform those who work in academia or R&D about both the delivery of food compounds via encapsulation and food processing using immobilized cells or enzymes. The structure of the book is according to the use of encapsulates for a specific application. Emphasis is placed on strategy, since encapsulation technologies may change. Most chapters include application possibilities of the encapsulation technologies in specific food products or processes. The first part of the book reviews general technologies, food-grade materials, and characterization methods for encapsulates. The second part discusses encapsulates of active ingredients (e.g., aroma, fish oil, minerals, vitamins, peptides, proteins, probiotics) for specific food applications. The last part describes immobilization technologies of cells and enzymes for use within food fermentation processes (e.g., beer, wine, dairy, meat), and food production (e.g., sugar conversion, production of organic acids or amino acids, hydrolysis of triglycerides). Edited by two leading experts in the field, Encapsulation Technologies for Food Active Ingredients and Food Processing will be a valuable reference source for those working in the academia or food industry. The editors work in both industry or academia, and they have brought together in this book contributions from both fields.

Enchanted by Daphne: The Life of an Evolutionary Naturalist

by Peter R. Grant

The extraordinary life story of the celebrated naturalist who transformed our understanding of evolutionEnchanted by Daphne is legendary ecologist Peter Grant’s personal account of his remarkable life and career. In this revelatory book, Grant takes readers from his childhood in World War II–era Britain to his ongoing research today in the Galápagos archipelago, vividly describing what it's like to do fieldwork in one of the most magnificent yet inhospitable places on Earth. This is also the story of two brilliant and courageous biologists raising a family together while balancing the demands of professional lives that would take them to the far corners of the globe.In 1973, Grant and his wife, Rosemary, embarked on a journey that would fundamentally change how we think about evolution. Over the next four decades, they visited the Galápagos every year to observe Darwin’s famous finches on the remote, uninhabited island of Daphne Major. Documenting how eighteen species have diversified from a single ancestral species, they demonstrated that we could actually see and measure evolution in a natural setting. Grant recounts the blind alleys and breathtaking triumphs of this historic research as he and Rosemary followed in Darwin’s footsteps—and ushered in a new era in ecology.A wonderfully absorbing portrait of a life in science, Enchanted by Daphne is an unforgettable chronicle of the travels and discoveries of one of the world’s most influential naturalists.

Enclosed Experimental Ecosystems and Scale

by W. Michael Kemp John E. Petersen William C. Dennison Victor S. Kennedy

Enclosed ecosystem experiments have gained in popularity as research tools in ecological science, particularly in the study of coastal aquatic environments. These systems provide scientists with a degree of experimental control that is not achievable through field experiments. Yet to date, techniques for systematically extrapolating results from small-scale experimental ecosystems to larger, deeper, more open, more biologically diverse, and more heterogeneous ecosystems in nature have not been well developed. Likewise, researchers have lacked methods for comparing and extrapolating information among natural ecosystems that differ in scale. Enclosed Experimental Ecosystems and Scale: Tools for Understanding and Managing Coastal Ecosystems provides scientists, managers, and policy makers with an introduction to what has been termed the "problem of scale", and presents information that will allow for improved design and interpretation of enclosed experimental aquatic ecosystems. The book integrates the results of a 10-year research project involving a multi-disciplinary team of scientists and students to explore scale-related questions in a variety of coastal habitats. Anticipating use as a reference, the book has been designed so that individual sections and individual pages can function as stand alone units.

Uma nova visão sobre a Evolução Humana De onde viemos, como vivemos ou porque temos esta aparência são algumas das questões fundamentais que nos ocorrem nalgum ponto das nossas vidas. A evolução humana é um campo em constante mudança, não havendo, por isso, respostas certas nem perguntas erradas. Neste livro fascinante, Sang-Hee Lee explora e questiona alguns dos pressupostos evolutivos a partir de novos e inesperados ângulos. A agricultura foi um passo em falso na evolução humana? Porque é o parto tão difícil para as mulheres? Porque é que os humanos adultos bebem leite? O que temos em comum com os neandertais? As histórias presentes neste livro oferecem uma nova perspetiva sobre os primeiros hominíneos, desafiando as perceções sobre a progressão tradicional da evolução. Combinando uma visão antropológica com investigação inovadora, as surpreendentes conclusões da autora lançam uma nova luz sobre os primórdiosda humanidade. À medida que avançamos na evolução, Lee ajuda-nos a determinar para onde caminhamos e aborda uma das questões científicas mais urgentes: será que a humanidade continua a evoluir? Os elogios da crítica: «Um dos melhores livros de ciências do ano.» -Instituto Smithsonian «De forma sucinta e cativante, Lee revisita as principais questões sobre a história da evolução da nossa espécie.» - Nature «Uma nova visão sobre a nossa singularidade.» - New Scientist

Encouraging Foreign Direct Investment: The key factors for long-term investment sustainability (SpringerBriefs in Energy)

by Tareq Mahbub

This book identifies and investigates the determinants that influence investment decision-making for conducting foreign direct investment (FDI) in Bangladesh’s power sector. This book is organized around six core themes. These are: Bangladesh’s vision to become a middle-income country by 2021 and have universal power for all; an overview of the benefits and costs of FDI from a host nation’s perspective; an outlook of Bangladesh’s power sector starting from the years 1994-2008 through 2011-2015 to 2016-2020 and beyond; the key factors that encourage foreign investors to conduct FDI in the Bangladeshi power sector subsumed under four broad categories of investment prospects namely, regulatory, economic and financial, political and social; the key barriers that deter FDI in the Bangladeshi power sector; and policy implications for long-term investment sustainability in the power sector.The main arguments posited in this book are: regulatory aspects are the most important for firms when conducting FDI in the power sector; land acquisition is a perineal problem that continues to hamper the development of large-scale power projects; there is a need for a transparent and competitive selection process to improve transparency and accountability in private power procurement; and more exploration of onshore and offshore gas fields with the extension of gas transmission networks be enhanced that ensure a regional balance of primary energy supply (gas) for setting up additional gas-based power plants in the country.
