Download and read online ebook Cellular Effects of Heavy Metals write by Gaspar Banfalvi. This book was released on 2011-03-02. Cellular Effects of Heavy Metals available in PDF, EPUB and Kindle. The term “heavy metals” is used as a group name of toxic metals and metalloids (semimetals) causing contaminations and ecotoxicity. In strict chemical sense the density of heavy metals is higher than 5 g/cm3. From biological point of view as microelements they can be divided into two major groups. a. For their physiological function organisms and cells require essential microelements such as iron, chromium (III), cobalt, copper, manganese, molidenium, zinc. b. The other group of heavy metals is toxic to the health or environment. Of highest concern are the emissions of As, Cd, Co, Cu, Hg, Mn, Ni, Pb, Sn, Tl. The toxicity of heavy metals is well known at organizational level, while less attention has been paid to their cellular effects. This book describes the toxicity of heavy metals on microorganisms, yeast, plant and animal cells. Other chapters of the book deal with their genotoxic, mutagenic and carcinogenic effects. The toxicity of several metals touch upon the aspects of environmental hazard, ecosystems and human health. Among the cellular responses of heavy metals irregularities in cellular mechanisms such as gene expression, protein folding, stress signaling pathways are among the most important ones. The final chapters deal with biosensors and removal of heavy metals. As everybody is eating, drinking and exposed to heavy metals on a daily basis, the spirit of the book will attract a wide audience.

Download and read online ebook Handbook of Cellular Metals write by Hans Peter Degischer. This book was released on 2002. Handbook of Cellular Metals available in PDF, EPUB and Kindle. The past few years have seen an increasing interest in porous metallic materials, especially in foams made of aluminum or aluminum alloys. The stimulus for this lies in recent process developments which promise materials with better quality and lower cost. Moreover, the environment for the application of new materials has greatly changed. Nowadays higher demands for passenger safety in automobiles or for easy materials recycling make metal foams attractive where, a few years ago, the same material would have been ruled out for technical or economical reasons. This handbook gives any materials scientist and engineer involved in the research, development and application of metal foams an overview on the most recent results on new production processes, applications and industrial uses as well as the important topic of characterization and properties of these advanced materials.

Download and read online ebook Thermo-Fluid Behaviour of Periodic Cellular Metals write by Tian Jian Lu. This book was released on 2015-04-29. Thermo-Fluid Behaviour of Periodic Cellular Metals available in PDF, EPUB and Kindle. Thermo-Fluid Behaviour of Periodic Cellular Metals introduces the study of coupled thermo-fluid behaviour of cellular metals with periodic structure in response to thermal loads, which is an interdisciplinary research area that requires a concurrent-engineering approach. The book, for the first time, systematically adopts experimental, numerical, and analytical approaches, presents the fluid flow and heat transfer in periodic cellular metals under forced convection conditions, aiming to establish structure-property relationships for tailoring material structures to achieve properties and performance levels that are customized for defined multifunctional applications. The book, as a textbook and reference book, is intended for both academic and industrial people, including graduate students, researchers and engineers. Dr. Tian Jian Lu is a professor at the School of Aerospace, Xi’an Jiaotong University, Xi’an, China. Dr. Feng Xu is a professor at the Key Laboratory of Biomedical Information Engineering of Ministry of Education, School of Life Science and Technology, Xi’an Jiaotong University. Dr. Ting Wen is now an engineer at Shell Global Solutions Inc. Dr. Lu and Dr. Xu are also affiliated with Biomedical Engineering and Biomechanics Center, Xi’an Jiaotong University.
Cellular Metals and Polymers

Download and read online ebook Cellular Metals and Polymers write by R.F. Singer. This book was released on 2005-06-15. Cellular Metals and Polymers available in PDF, EPUB and Kindle. This collection constitutes an essential sourcebook for researchers, producers and users seeking technical information on materials with foam-like structures. The collection is unique, in that it brings together people from the fields of metals and polymers. Both material types derive their advantageous properties from a cellular structure. These properties include: low weight, high specific stiffness and strength, excellent energy absorption capacity, as well as damping and insulation properties. On the other hand, the processing of metals is far more difficult due to the higher temperatures involved. Another important factor is the faster decay of metal foam structures, at the end of the foaming process, because of their combination of high surface tension and low viscosity. The differences in foamability, between metals and polymers, explain why cellular plastics have been widely used for some time whereas cellular metals have only recently found their first applications.

Download and read online ebook Processing and Properties of Lightweight Cellular Metals and Structures write by Amit Kumar Ghosh. This book was released on 2002. Processing and Properties of Lightweight Cellular Metals and Structures available in PDF, EPUB and Kindle. Cellular metals and designed porous structures are attractive, lightweight structural materials with potential applications in the transportation, electronics, biomedical, defense, building, and energy-based industries. Metal foams, sponge-like metals, and periodic geometry core structures are increasingly being considered as solutions to problems such as lightweight construction, heat exchangers, passive safety, sound dampening, filtering, and thermal stability. Momentum for the widespread use of cellular metal technology has been rising, but the field still remains at an early developmental stage. Processing and Properties of Lightweight Cellular Metals and Structures captures the current status of this emerging enabling technology. This book underscores the scientific community's enthusiasm in the outstanding potential of this unique group of materials and structures and hopes to stimulate even greater interest among research sponsors and industry. Papers cover a variety of key areas of development, such as new design concepts and functional properties, new processing technologies, microstructure and property characterization, reinforcement of foam metals, modeling of properties, component fabrication, and applications.
