This book mainly focuses on the theoretical and experimental study of non-Fourier heat conduction behavior. A novel thermomass theory is used as the theoretical basis, which provides a general heat conduction equation for the accurate prediction of non-Fourier heat conduction. In order to prove the validity of this thermomass theory, a large current was used to heat the metallic nanofilm at the minimum temperature of 3 K. The measured average temperature of the nanofilm was notably higher than the prediction of Fourier's heat diffusion equation, while matching well with the general heat conduction equation. This is the first time that steady non-Fourier heat conduction has been observed. Moreover, this book concerns the role of electron-phonon interaction in metallic nanofilms, which involves the breakdown of the Wiedemann-Franz law at low temperatures and interfacial thermal resistance at femtosecond timescales. Readers will find useful information on non-Fourier heat conduction and the latest advances in the study of charge and heat transport in metallic nanofilms.

This book provides a comprehensive and up-to-date account of the HPLC technology and fingerprints of commonly-used Chinese herbs. It contains HPLC fingerprints of over 40 traditional Chinese medicinal herbs and details of their sources, production and quality control. The book provides a practical review of the techniques, relevant materials, and the particular demands for using HPLC in traditional Chinese medicinal herb applications. It also covers HPLC methods used to analyze the herbs.High-performance liquid chromatography (HPLC) is increasingly used in the field of traditional Chinese medicine for obtaining fingerprints of Chinese medicinal herbs. Advantages such as high speed, high resolution, high sensitivity, stability, accuracy, and automation make it one of the leading techniques used for quality control, standardization of planting, and new drug development in traditional Chinese medicine.To date, no other books on HPLC fingerprints of traditional Chinese medicinal herbs have been published in English. This is the first book in English devoted to providing readers with state-of-the-art information on HPLC applied in the analysis of traditional Chinese medicinal herbs.
