Porous media exist in different modern materials. It presents great surface areas with small pore size distribution. These types of materials with controllable and adjustable pore diameters are given considerable attention due to their suitable properties and applications in several fields. Porous materials have many applications in our daily life. We use different types of porous materials to clean our drinking water, for instance. This new research-oriented volume focuses on exploring the wide range of porous materials. In this new volume, original contributions from international authors along with case studies on the synthesis, design, characterization, and applications of different types of porous materials and solids are presented in detail. The book covers different types of porous materials in the broad sense by considering experimental and theoretical aspects of materials science related to porous materials and solids. The book aims to help approach characterizing a particular types of materials for more in-depth analysis. This book is divided into three parts to determine the best techniques for solving particular porous materials problems, and in each part, the fabrication and characterization of porous materials are explored with applications, describing new methodologies to gain the required information along with limitations of various methods. To make this new title a practical reference book for research students and for engineers and scientists of different disciplines working with porous materials and solids, the editors have selected a very comprehensive range of case studies as well, designed to cover the basic concepts of porosity. These case studies also describe different types of pores and surfaces for readers.

For a large number of applications involving surface interactions, there is an ever growing demand for materials with high specific surface area (surface area to volume ratio). Porous materials and nanomaterials offer higher specific surface area (SSA) each with their respective advantages and disadvantages. This research program is focused on bringing the two approaches together to create truly "hierarchical" materials that combine advantages of both while minimizing their disadvantages. In this study, various carbon based porous geometries were fabricated by grafting carbon nanotubes (CNT) onto highly porous reticulated carbon foams. These structures were further modified by functionalizing metal nanoparticles such as silver (Ag). Carbon as the base material provides desirable structural, thermal and electrical properties combined with environmental inertness. Silver nanoparticles have important anti-bacterial applications as well as future potential as sensors and electro-active devices. Mathematical models and fluid permeability tests were performed to enable comparison and adaptation of hierarchical porous structures for potential water treatment devices. Surface wettability was modified via liquid phase sol-gel method. Carbon nanotube grafted surfaces were coated with silica and influence of these coatings on surface wettability, fluid permeability, nanoparticle growth, and antibacterial efficiency were studied. Microstructure characterization of CNT grafted surfaces, silica modification, and nanoparticle deposition of these structures was studied using secondary (SE), backscatter (BE), and scanning transmission (STEM) electron microscopy. Chemical composition and surface chemistry of these structures were studied using energy dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS) respectively. Crystallographic studies were done using X-ray diffraction (XRD) studies. Influence of CNT grafting and silica coatings on surface wettability was studied via static contact angle measurements. The anti-bacterial performance of these materials under different types of water flow configurations were tested with gram negative E. Coli K12 bacteria. Water permeability measurements of the different surface modifications on hierarchical porous structures were performed and correlated with porous structure at micro and nano scales. This study provides a comprehensive ground work for next generation functional hierarchical materials suitable for water purification devices.
