R10,412 Discovery Miles 104 120 Ships in 12 - 19 working days

This book provides a comprehensive and authoritative review of the chemical analysis of UV filters in coastal waters and their impact on the marine environment. The sun care is today the most important sector within the cosmetics industry, with annual increases in sales. The main components of sunscreens, organic and inorganic UV filters, have been detected in many coastal regions, with the highest concentrations in coastal areas under high anthropogenic pressure. Moreover, these compounds have been found to be bioaccumulated in aquatic biota causing biological and toxicological responses; some organic UV filters act as endocrine disruptors in aquatic biota, affecting survival, behavior, growth, development and reproduction. On the other hand, inorganic UV filters, mainly based on nanoparticles, have been demonstrated to have various impacts on marine organisms, such as inducing oxidative stress in abalones, accumulating in microalgae, affecting the immune response in mussels, bleaching corals, and genotoxicity in fish, among others. All these effects of sunscreens on the marine environment highlight the need for more stringent and environmentally friendly regulations. This book covers the latest analytical methodologies used in assessing the impact of UV filters impact on marine waters, especially on marine biota, and also critiques the global regulation of UV filters and the environmental risk of using sunscreens. Featuring specific case studies of the environmental effects of sunscreens in the Mediterranean Sea and Hawaii, which highlight the importance of balancing human health with environmental health of coastal ecosystems, it will appeal not only to scientists and students from various disciplines (environmental chemistry, biology, ecology, biogeochemistry, fisheries and climate change among others), but also to environmental managers wanting to promote new restrictive regulations on the use of UV filters, and to professionals from the cosmetic industry interested in the development of eco-friendly sunscreens.

Social Drivers In Food Technology (Hardcover, 1st ed. 2020): Vivian-Lara Silva Social Drivers In Food Technology (Hardcover, 1st ed. 2020)
Vivian-Lara Silva
R1,521 Discovery Miles 15 210 Ships in 10 - 15 working days

This unique and timely text is designed to help food science students learn to perform critical analysis of food processing technology and consider the incorporation of elements that touch on contemporary technological developments in the food sector. As the food industry adjusts to new consumer demands for safe and low processed foods, the time has come to harmonize product and process engineering with 'relationship engineering' from farm to fork. This increasingly allows the opportunity for food sector professionals to consider the existence of new drivers of food consumption. These newly discovered drivers are explored in great detail over the course of this book from industrial, economic and human resource viewpoints. Social Drivers In Food Technology presents a series of helpful case studies are presented covering six important food sectors: chocolate, coffee, yogurt, juice, baby food and snacks. These cases have been chosen in order to illustrate dynamic and innovative advances in food processing technology. The information provided over the course of this book has been gained through the thorough study of both scientific literature and organizational reports from food processing companies. The major economic aspects related to food technology are also outlined throughout the text. This multidisciplinary approach is motivated by the opportunity to contextualize the technological debate in strategy and organizational economics, contributing to the formation of human resources. This text is informed by the concept that one must look beyond the technology of the food processing sector and discuss opportunities that involve re-thinking product innovation and process, knowledge generation and human resource training. These innovations have been highlighted in food science & technology literature, but their economic and managerial implications have remained unexplored until now. With its informative case studies, helpful illustrations and quizzes and comprehensive, well-organized scope, Social Drivers In Food Technology is a much-needed textbook that will allow students to look at food processing technology from both industrial and economic perspectives and to consider the important human resource elements involved.

In this book, the development of next-generation batteries is introduced. Included are reports of investigations to realize high energy density batteries: Li-air, Li-sulfur, and all solid-state and metal anode (Mg, Al, Zn) batteries. Sulfide and oxide solid electrolytes are also reviewed.A number of relevant aspects of all solid-state batteries with a carbon anode or Li-metal anode are discussed and described: The formation of the cathode; the interface between the cathode (anode) and electrolyte; the discharge and charge mechanisms of the Li-air battery; the electrolyte system for the Li-air battery; and cell construction. The Li-sulfur battery involves a critical problem, namely, the dissolution of intermediates of sulfur during the discharge process. Here, new electrolyte systems for the suppression of intermediate dissolution are discussed. Li-metal batteries with liquid electrolytes also present a significant problem: the dendrite formation of lithium. New separators and electrolytes are introduced to improve the safety and rechargeability of the Li-metal anode. Mg, Al, and Zn metal anodes have been also applied to rechargeable batteries, and in this book, new metal anode batteries are introduced as the generation-after-next batteries.This volume is a summary of ALCA-SPRING projects, which constitute the most extensive research for next-generation batteries in Japan. The work presented in this book is highly informative and useful not only for battery researchers but also for researchers in the fields of electric vehicles and energy storage.

Peter Schwerdtfeger
R8,287 Discovery Miles 82 870 Ships in 12 - 19 working days

The field of relativistic electronic structure theory is generally not part of theoretical chemistry education, and is therefore not covered in most quantum chemistry textbooks. This is due to the fact that only in the last two decades have we learned about the importance of relativistic effects in the chemistry of heavy and superheavy elements. Developments in computer hardware together with sophisticated computer algorithms make it now possible to perform four-component relativistic calculations for larger molecules. Two-component and scalar all-electron relativistic schemes are also becoming part of standard ab-initio and density functional program packages for molecules and the solid state. The second volume of this two-part book series is therefore devoted to applications in this area of quantum chemistry and physics of atoms, molecules and the solid state. Part 1 was devoted to fundamental aspects of relativistic electronic structure theory whereas Part 2 covers more of the applications side. This volume opens with a section on the Chemistry of the Superheavy Elements and contains chapters dealing with Accurate Relativistic Fock-Space Calculations for Many-Electron Atoms, Accurate Relativistic Calculations Including QED, Parity-Violation Effects in Molecules, Accurate Determination of Electric Field Gradients for Heavy Atoms and Molecules, Two-Component Relativistic Effective Core Potential Calculations for Molecules, Relativistic Ab-Initio Model Potential Calculations for Molecules and Embedded Clusters, Relativistic Pseudopotential Calculations for Electronic Excited States, Relativistic Effects on NMR Chemical Shifts, Relativistic Density Functional Calculations on Small Molecules, Quantum Chemistry with the Douglas-Kroll-Hess Approach to Relativistic Density Functional Theory, and Relativistic Solid State Calculations.
- Comprehensive publication which focuses on new developments in relativistic quantum electronic structure theory
- Many leaders from the field of theoretical chemistry have contributed to the TCC series
- Will no doubt become a standard text for scientists in this field.

R2,873 Discovery Miles 28 730 Ships in 10 - 15 working days

This book presents the theoretical and experimental investigations on antiferromagnetically coupled ferrimagnets and reveals new aspects of ferrimagnetic dynamics in terms of the role of angular momentum. The purpose of this book is to show readers that antiferromagnets/ferrimagnets are useful in spintronic devices in that (1) The non adiabatic spin transfer torque in antiferromagnets acts as a staggered magnetic field, which can drive the magnetic domain walls, and (2) The Gilbert damping parameter , the energy dissipation rate associated with the magnetic dynamics of ferrimagnets, is insensitive to temperature in contrast to the conventional understanding that the effective of ferrimagnets diverges at the angular momentum compensation temperature. This book provides readers with a scientific platform of ferrimagnetic dynamics, which serves as a useful basis for realizing the next generation of spintronic devices.
