Book Description
Nanoscale ionic materials (NIMS) are a hybrid organic-inorganic liquid-like material consisting of a hard inorganic nanocore and an organic canopy. The high nanoparticle content, zero vapor pressure and inexpensive mass production capabilities give NIMS the ability to develop into sustainable metamaterials that outperform traditional nanofluids in cost and efficiency. Current heat transfer materials are limited by nanoparticle saturation. NIMS, with their superior nanoparticle concentration and stability, may be a more effective and environmentally friendly substitution for these products. Investigation of this requires a reliable method of determining the thermal diffusivity of NIMS. The laser flash analysis (LFA) method of experimentally determining the thermal properties of nanofluids was applied to NIMS of varying compositions at room temperature. Despite promising preliminary results, LFA is not yet a reliable method of characterizing the thermal properties of NIMS. In spite of obstacles in experimental measurement, LFA still appears to be the most viable method for thermal measurement of NIMS. Further improvements to experimental techniques may lead to standardization of thermal diffusivity of NIMS.

Book Description
Thermal measurement is a critical part of determining the thermal properties of materials. Conventional steady-state thermal conductivity measurements have strict requirements on the sample dimensions and states, making it hard to measure most unconventional samples. Laser flash analysis (LFA) is a convenient and reliable method of determining different materials' thermal diffusivity and thermal conductivity. Apart from LFA, FDTR (Frequency Domain Thermoreflectance) is a much more powerful tool for thermal measurements, where samples with almost all dimensions and states can be measured. FDTR is thermal property microscopy that utilizes two lasers (pump and probe lasers) to measure the samples' thermal properties. The periodically modulated pump laser locally heats the sample. The probe laser detects the surface reflectivity of the sample, which can be used to calculate the thermal properties of the sample with models. Instead of only measuring the sample's thermal conductivity, the FDTR system can measure up to two properties at once - including volumetric heat capacity, thermal conductivity, thickness, interfacial conductivity, and the anisotropic ratio of thermal conductivity of the sample. This thesis demonstrates how LFA works and how it conducts measurements for polymeric composites and polymer blend samples. Also, this thesis concludes on how to set up an FDTR system and how it works on thermal measurements.

Book Description
This volume offers a comprehensive examination of the subject of heat and mass transfer with nanofluids as well as a critical review of the past and recent research projects in this area. Emphasis is placed on the fundamentals of the transport processes using particle-fluid suspensions, such as nanofluids. The nanofluid research is examined and presented in a holistic way using a great deal of our experience with the subjects of continuum mechanics, statistical thermodynamics, and non-equilibrium thermodynamics of transport processes. Using a thorough database, the experimental, analytical, and numerical advances of recent research in nanofluids are critically examined and connected to past research with medium and fine particles as well as to functional engineering systems. Promising applications and technological issues of heat/mass transfer system design with nanofluids are also discussed. This book also: Provides a deep scientific analysis of nanofluids using classical thermodynamics and statistical thermodynamics to explain and interpret experimental observations Presents the theory and experimental results for both thermodynamic and transport properties Examines all transport properties and transport processes as well as their relationships through the pertinent macroscopic coefficients Combines recent knowledge pertaining to nanofluids with the previous fifty years of research on particulate flows, including research on transient flow and heat transfer of particulate suspensions Conducts an holistic examination of the material from more than 500 archival publications

Book Description
Organized nanoassemblies of inorganic nanoparticles and organic molecules are building blocks of nanodevices, whether they are designed to perform molecular level computing, sense the environment or improve the catalytic properties of a material. The key to creation of these hybrid nanostructures lies in understanding the chemistry at a fundamental level. This book serves as a reference book for researchers by providing fundamental understanding of many nanoscopic materials.

Book Description
It has been almost thirty years since the publication of a book that is entirely dedicated to the theory, description, characterization and measurement of the thermal conductivity of solids. The recent discovery of new materials which possess more complex crystal structures and thus more complicated phonon scattering mechanisms have brought innovative challenges to the theory and experimental understanding of these new materials. With the development of new and novel solid materials and new measurement techniques, this book will serve as a current and extensive resource to the next generation researchers in the field of thermal conductivity. This book is a valuable resource for research groups and special topics courses (8-10 students), for 1st or 2nd year graduate level courses in Thermal Properties of Solids, special topics courses in Thermal Conductivity, Superconductors and Magnetic Materials, and to researchers in Thermoelectrics, Thermal Barrier Materials and Solid State Physics.

Book Description
Introduction to Thermoelectricity is the latest work by Professor Julian Goldsmid drawing on his 55 years experience in the field. The theory of the thermoelectric and related phenomena is presented in sufficient detail to enable researchers to understand their observations and develop improved thermoelectric materials. The methods for the selection of materials and their improvement are discussed. Thermoelectric materials for use in refrigeration and electrical generation are reviewed. Experimental techniques for the measurement of properties and for the production of thermoelements are described. Special emphasis is placed on nanotechnology which promises to yield great improvements in the efficiency of thermoelectric devices. Chapters are also devoted to transverse thermoelectric effects and thermionic energy conversion, both techniques offering the promise of important applications in the future.
