Preface

The synthesis and study of clays and clay minerals are some of the widest fields of research in materials science and technology. Characterization and application of many derived clay materials with different polymers and organic and biological molecules are attracting great interest from scientists and researchers, especially with the emergence of nanotechnology. The catalytic behavior of some clay surfaces can change the properties of adsorbed or intercalated molecules. Theoretical approaches using ab initio, quantum chemical, and Monte Carlo calculations combined with new spectroscopic techniques are expanding the knowledge of clay properties. New two-dimensional materials based on clays and clay minerals are attracting attention for their outstanding properties that make them useful as hosts or supporting matrixes in applications such as pharmaceuticals, tissue engineering, environmental remediation, biosensors, filtration, wound dressings, drug delivery, enzyme immobilization, 3D printing, and more. This book is a comprehensive overview of clay science and technology, focusing on synthesis, characterization, simulation, and applications. It is divided into two parts: "Clay Properties and

Chapter 3 focuses on the thermodynamics and kinetics of removing copper (II) and methyl orange from an aqueous solution using natural clay and its composites.

Chapter 4 presents the chemical, mineralogical, and rheological characterization of samples from four clay deposits before and after fractionation. These raw clays are used in the production of ceramic tiles, bricks, blocks, and artisanal pieces in Sergipe, Brazil, for possible use in high value-added products such as cosmetics and

Chapter 5 examines one-dimensional natural clay decorated with magnetic nanoparticles of Fe3O4. The material is well characterized by different physicalchemical techniques. The chapter shows that the functionalization of one-dimensional clay minerals has potential applications in display devices, photonic switches,
