Book Description
Clay Nanoparticles: Properties and Applications sets out the major properties of clay nanoparticles and their technological applications. The first part of the book focuses on the characterization of nanoclays, including layered, fibrous and tubular clay minerals. The second part illustrates the current and potential applications of nanoclays within material science and biotechnology. These include the development of geopolymers and bionanocomposites based on sustainable polymers filled with ecocompatible nanoclay. The potential use of nanoclays as flame retardants is also discussed, along with the correlation between the properties and potential applications of several nanoclay types. In particular, the applications explored include nanoclays as drug delivery systems and for environmental protection. The book provides a complete and multidisciplinary exploration of nanoclays, highlighting a range of perspectives within current nanotechnology research. Assesses the advantages of using nanoclays instead of conventional clay materials in product design Describes the major characterization techniques - both experimental and computational - for nanoclays Explores new fabrication techniques based on pristine and modified clay nanoparticles that are being used both in materials science and biotechnology

Book Description
El presente trabajo, objeto de esta memoria de tesis doctoral, se ha realizado para profundizar en el conocimiento del comportamiento y mecanismo de las reacciones de las Adiciones Puzolanicas que tradicionalmente se utilizan en las industrias del cemento y del hormigon, frente al ataque de los iones [SO(4)](2-) en forma de yeso, CaSO(4).2 H(2)O.Por ello se ha realizado un estudio global de las mismas (merced a la eleccion adecuada de varias de ellas, D,N,O,A,C,M,CV-10 y CV-19, para tal fin), en forma de cementos de mezcla constituidos unicamente por cemento Portland, P o PY, y Puzolana, hasta un 40% en peso de estas ultimas, respectivamente. A continuacion, a cada cemento de mezcla citado, se le ha añadido la cantidades oportunas de yeso, CaSO(4).2 H(2)O,como agresivo (15.03%, 33.33% y 45.16% en peso, respectivamente) para tratar de ...

Book Description
The subject of mineralogy is moving away from the traditional systematic treatment of mineral groups toward the study of the behaviour of minerals in relation to geological processes. A knowledge of how minerals respond to a changing geological environment is fundamental to our understanding of many dynamic earth processes. By adopting a materials science approach, An Introduction to Mineral Sciences explains the principles underlying the modern study of minerals, discussing the behaviour of crystalline materials with changes in temperature, pressure and chemical environment. The concepts required to understand mineral behaviour are often complex, but are presented here in simple, non-mathematical terms for undergraduate mineralogy students. After introductory chapters describing the principles of diffraction, imaging and the spectroscopic methods used to study minerals, the structure and behaviour of the main groups of rock-forming minerals are covered, and the role of defects in the deformation and transformation of a mineral are explained. The energy changes and the rate of transformation processes are introduced using a descriptive approach rather than attempting a complete and rigorous treatment of the thermodynamics and kinetics. Examples and case histories from a range of mineral groups are set in an earth science context, such that the emphasis of this book is to allow the student to develop an intuitive understanding of the structural principles controlling the behaviour of minerals.
