This edition of our book on thermal conductivity is geared specifically to the needs and background of research students. In reviewing different comments, we have made modifica‐ tions in some parts of the book to enhance reader understanding of the material. This book focuses on the thermal properties in different materials using novel experimental and com‐ putational methods and discloses the exact nature and origin of different approaches of sys‐ tems. New methods for investigating thermal properties in various devices are required for improving device design and for understanding device physics and technology. Such meth‐ ods are also required for studying new thermal phenomena in micro- to nano-scale devices made up of novel nanostructures, such as carbon electronics or semiconductor nanowires, nanometer size sensors to detect proteins or single DNA and nanolevel fluidic flow, nano‐ powder production, nanocrystalline solar cells, and polymer coatings with embedded nano particles. Thermal conductivity, heat process, and their nonlinear effects (non-Newtonian behaviors) are the basic elements of the transport property of complex liquids and are ap‐ plied for studying their flow, heat, and mass transfer characteristics. Among the changes we have made in this edition are the following. In the first section "Thermal Conductivity of Complex Systems," we have explained the discussion of the thermal conductivity of com‐ plex dusty plasma system and discussed the thermal conductivity of non-Newtonian fluid with particle suspension, ionic fluids, and synthetic and regenerated fiber assemblies. In the second section "Thermal Conductivity of Solid and Fluid Systems," we have incorporated material on liquid metals, molten systems at high temperatures, hydrate-bearing porous sediments, and vacuum glazing systems. In the third section "Thermal Conductivity of Nano Systems," we explained the structural and thermoelectric properties of single crystal‐ line nanowire, nonlinear heat transfer of nano particles, and graphite-based polymer.

I hope this book will fulfill all the needs of the research students of different universities and
