This book was released on 2017 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clay minerals play considerable importance in geotechnical, agricultural, and pharmaceutical applications. They are made of plate-like particles with micrometer dimensions and play a critical role in problems involving swelling, deformation, and failure in geomaterials. Understanding of these phenomena and the parameters that influence them requires studies at the nanoscale.

Available in PDF, EPUB and Kindle. Book excerpt: Surface and Interface Chemistry of Clay Minerals, Volume 9, delivers a fundamental understanding of the surface and interface chemistry of clay minerals, thus serving as a valuable resource for researchers active in the fields of materials chemistry and sustainable chemistry. Clay minerals, with surfaces ranging from hydrophilic, to hydrophobic, are widely studied and used as adsorbents. Adsorption can occur at the edges and surfaces of clay mineral layers and particles, and in the interlayer region. This diversity in properties and the possibility to tune the surface properties of clay minerals to match the properties of adsorbed molecules is the basis for study. This book requires a fundamental understanding of the surface and interface chemistry of clay minerals, and of the interaction between adsorbate and adsorbent. It is an essential resource for clay scientists, geologists, chemists, physicists, material scientists, researchers, and students. - Presents scientists and engineers with a resource they can rely on for their own research and work involving clay minerals - Includes an in-depth look at ion exchange, adsorption of inorganic and organic molecules, including polymers and proteins, and catalysis occurring at the surfaces of clay minerals - Includes materials chemistry of clay minerals with chiral clay minerals, optical materials and functional films

This book was released on 1974 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous studies indicated that when water-ice phase composition curves are normalized to unit surface area, the unfrozen water content values at given temperatures for the kaolinite/water system are higher than those of other soils and soil constituents. The water-ice phase composition curve for this system has been redetermined using an improved isothermal calorimeter and the earlier curve confirmed. (Modified author abstract).

Available in PDF, EPUB and Kindle. Book excerpt: This text is a compendium of five decades of work relating to science, mechanics and improvement of highly expansive soil systems, application of improved methods to construction of stable civil engineering structures on such deposits. He has used a particulate approach incorporating thermodynamic properties of soil particles as matter to predict the behaviour of saturated expansive soil. The compiling of this massive work has been the effort of the co-authors. The behaviour of expansive soil deposits is found to be unconventional in nature. Prof. Katti has focused on the difference in behaviour by conducting identical studies on conventional soil systems. The book covers topics on basic property, swelling and swelling pressure measurements, shear strength behaviour under various conditions including depth effect, lateral earth pressure development under Ka, Ko and Kp conditions using large-scale devises, discovery of CNS technology and its field application, bearing capacity aspect with and without CNS and MSM, expansive soil improvement techniques, approach to design of rigid and flexible pavements, shallow and raft foundations; optimum length, Hd of underreamed piles, similarity between suction pressure measure approach and cohesion measure approach, use of conventional and small scale test data and simplified approach to estimate he and h, standards, and mechanics of expansive soil media and case histories. He has brought about limitations of existing conventional theories to deal with expansive soil behaviour and the need for incorporating thermodynamic parameters to predict behaviour of saturated expansive soils. This is a unique treatise covering the entire realm of behaviour of saturated expansive soil and control methods. It can act as a database for future research workers and scholars as a guide for construction for practicing engineers and as a sequentially organised scientifically based book for students.

This book was released on 2018 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clay and clay minerals have always been used since the ancient times for making ceramic materials and also as a building material. Over the past decades, there has been a growing trend in their applicability in different areas such as industries, environmental remediation and water treatment sectors. The growing trend is mainly associated with the fact that they are chemically and mechanically stable, have higher specific surface area and cation exchange capacity. Furthermore, clays can be modified to improve their functionalities in different sectors. In this chapter, we present a review of the structural, mineralogical and chemical properties of clay and the effect of surface modification in their structures. We further looked at their applicability in arsenic and fluoride removal in their raw and also in their modified form. Although the literature showed that modified clay minerals yields higher adsorption capacity as compared to raw clays little nothing has been reported yet in relation to the cost of modifying clays with chemical species. As such new studies should also elaborate on the cost effectiveness of modifying clay minerals with chemical species.

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive review of environmental remediation is presented with an emphasis on the role of clay minerals in water purification. In the first chapter, important aspects of environmental problems and possible solutions are discussed. In the second chapter, the application of natural clay minerals as environmental cleaning agents are explained. The discussion is focused on the role of different types of clay materials in hazardous substance removal from air, aqueous solutions, wastewater, aquaculture, ground water, etc. In the next chapter, the modification of clay materials is explored including the preparation of clay composite materials for environmental remediation. Various aspects of clay material modifications and the effects of clay surface chemistry on the removal of hazardous material is also discussed. Next, the equilibrium and kinetics of hazardous substance adsorption is presented. This chapter summarizes recent studies on the removal of hazardous substances from aqueous solutions and the environment using various types of clay minerals. The brief also includes various models used in adsorption studies and touches on the characterization of clay minerals.

Download or read book Multiscale Experimental and Numerical Study of the Structure and the Dynamics of Water Confined in Clay Minerals written by Emmanuel Guillaud and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clay are complex minerals with a multiscale porosity and a remarkable ability to swell under humid atmosphere. These materials have many applications in catalysis, waste management, construction industry... However, the properties of confined water are still not fully understood, due in particular to the complexity of water itself. The aim of this work is, using mainly molecular simulations and vibrational spectroscopy, to understand the structure and the dynamics of water confined in clay minerals. To evaluate the accuracy of numerical models to describe water confined in clay minerals, and to understand the origin of its structural and dynamical properties, a large part of the work was devoted to the building blocks of clays: pure bulk water, water at the surface of a solid, and salt water. To this extent, the viscoelastic properties of water from the deeply supercooled regime to the boiling temperature were investigated using classical molecular dynamics. The evolution of the friction properties of water on a prototypical solid surface was also analyzed, and the accuracy of ab initio approaches and empirical salt models was studied.In a second part, those results were confronted to the properties of water confined in clay minerals at low and room temperature, studied both experimentally and numerically. Experimental work consisted mostly in extensive far- and -mid infrared absorption spectrometry measurements, whereas numerical work mainly consisted in empirical molecular dynamics simulations. Especially, the existence of confinement- or temperature-induced phase transitions of confined water was investigated.
