The second law of thermodynamics states that entropy in nature always increases, with temperature being the conjugate variable associated with entropy. Temperature gradients act as driving forces, generating heat fluxes governed by thermal conductivity. As a result, thermal conductivity is fundamental to understanding entropy and heat transfer processes. On this foundation, this book focuses on recent advancements in the study of thermal conductivity and its role in applications such as nanofluids, nanocomposites, and nuclear fusion technologies. Readers will discover how innovations in thermal conductivity are transforming these fields and expanding the frontiers of science and engineering. This book, written for researchers and engineers, offers insights into the key mechanisms and challenges driving modern thermal applications.
