“Advances in Crystallization Processes” ed. by Yitzhak Mastai
Crystallization is used at some stage in nearly all process industries as a method of production, purification or recovery of solid materials. In recent years, a number of new applications have also come to rely on crystallization processes such as the crystallization of nano and amorphous materials.

Principles and Applications of Powder Diffraction

Principles and Applications of Powder Diffraction
English | Physics | 5. September 2008 | ISBN-10: 1405162228 | 400 pages | pdf | 10 mb
Powder diffraction is one of the primary techniques used to characterize materials, providing structural information even when the crystallite size is too small for single crystal x-ray diffraction methods.

Principles and Applications of Powder Diffraction
There has been a significant increase in the application of powder diffraction in recent years, both in research and manufacturing, fuelled by improved instrumentation, data processing and awareness of the information that can be obtained. Powder diffraction allows for rapid, non-destructive analysis of multi-component mixtures without the need for extensive sample preparation. This gives laboratories the ability to quickly analyse unknown materials and perform materials characterization in such fields as chemistry, materials science, geology, mineralogy, forensics, archaeology, and the biological and pharmaceutical sciences.

This book provides a concise introduction to modern powder diffraction methods with particular emphasis on practical aspects. It covers the background theory of diffraction in a form approachable by those with an undergraduate degree. Whilst individual chapters are written as stand alone sections, the text is sufficiently focused so that it can be read in its entirety by the non-specialist who wants to gain a rapid overview of what they can do with modern powder diffraction methods.

Thermo-Gas Dynamics of Hydrogen Combustion and Explosion
by Boris E. Gelfand, Mikhail V. Silnikov, Sergey P. Medvedev, Sergey V. Khomik
English | 2012 | ISBN: 3642253512 | 345 pages | PDF | 11.02 MB

Thermo-Gas Dynamics of Hydrogen Combustion and Explosion
"The potential of hydrogen as an important future energy source has generated fresh interest in the study of hydrogenous gas mixtures. Indeed, both its high caloricity and reactivity are unique properties, the latter underscoring safety considerations when handling such mixtures. The present monograph is devoted to the various aspects of hydrogen combustion and explosion processes. In addition to theoretical and phenomenological considerations, this work also collates the results of many experiments from less well known sources. The text reviews the literature in this respect, thereby providing valuable information about the thermo-gas-dynamical parameters of combustion processes for selected experimental settings in a range of scientific and industrial applications."

Hydrogen Safety (Green Chemistry and Chemical Engineering)

Hydrogen Safety (Green Chemistry and Chemical Engineering) by Fotis Rigas and Paul Amyotte
English | 2012 | ISBN: 1439862311 | 304 pages | PDF | 19 MB
Hydrogen Safety highlights physiological, physical, and chemical hazards associated with hydrogen production, storage, distribution, and use systems. It also examines potential accident scenarios that could occur with hydrogen use under certain conditions.

Hydrogen Safety (Green Chemistry and Chemical Engineering)
The number of potential applications for hydrogen continues to grow-from cooling power station generators to widespread commercial use in hydrogen fuel-cell vehicles and other fuel-cell applications. However, this volatile substance poses unique challenges, including easy leakage, low ignition energy, a wide range of combustible fuel-air mixtures, buoyancy, and its ability to embrittle metals that are required to ensure safe operation.
Focused on providing a balanced view of hydrogen safety-one that integrates principles from physical sciences, engineering, management, and social sciences-this book is organized to address questions associated with the hazards of hydrogen and the ensuing risk associated with its industrial and public use.
* What are the properties of hydrogen that can render it a hazardous substance?
* How have these hazards historically resulted in undesired incidents?
* How might these hazards arise in the storage of hydrogen and with its use in vehicular transportation?
The authors address issues of inherently safer design, safety management systems, and safety culture. They highlight hydrogen storage facilities -which pose greater hazards because of the increased quantities stored and handled-and the dangers of using hydrogen as a fuel for transport. Presented experiments are included to verify computer simulations with the aid of computational fluid dynamics (CFD) of both gaseous and liquefied hydrogen. The book also provides an overview of the European Commission (EC) Network of Excellence for Hydrogen Safety (HySafe) and presents various case studies associated with hydrogen and constructional materials. It concludes with a brief look at future research requirements and current legal requirements for hydrogen safety.

Biological Effects of Surfactant

Biological Effects of Surfactants
English | 2005 | ISBN: 0849325269 | 304 pages | PDF | 11,7 Mb

Understanding the role of aquatic biota and the impact of pollution and chemical substances that enter aquatic ecosystems is crucial to the assessment, prevention, and remediation of damaged environments.

Biological Effects of Surfactants synthesizes the most important findings from hundreds of articles and the author’s current experiments on the biological effects of synthetic surfactants and detergents on individual organisms, populations, communities, and ecosystems. This book offers a new perspective of the hazards of pollution.
The book draws upon concepts in hydrobiology, biogeochemical cycling, and the assimilative capacity of water-beyond the self-purification capabilities of bacteria and nutrient cycling-to examine the effects of anionic, non-ionic, and cationic surfactants as well as detergent mixtures on a wide range of organisms including bacteria, cyanobacteria, flagellates, algae, higher plants, and invertebrates. The author, a distinguished member of the Russian Academy of Natural Sciences, establishes new quantitative characteristics of the effects and presents study results reflecting newly discovered phenomena. While proposing and substantiating new priorities and approaches for testing, assessing, and characterizing the biological activities and hazards of substances, he illustrates how the data obtained can be used to develop effective environmental remediation and protection measures to improve water quality.
Biological Effects of Surfactants lays an excellent foundation for scientists to explore how hazardous wastes are absorbed in aquatic and terrestrial ecosystems, determine what is required for remediation and restoring water quality, and design the best approach to counteract the toxic effects of manmade surfactants using biological methods, including phytoremediation.
