    The title is composed of two subjects that frequently appear in the discussion about the periodic heating method. The former part of the title means the minimum knowledge required to use the periodic heating method. Meaning of the latter part is clear but it should be noted that for development in future advantage of the periodic heating method has to be understood correctly by many researchers. The advantage will be explained by suitable authors in the following papers. In this short paper a few things considered to belong to the periodic heating method minimum are described.

    AC calorimetry allows one to measure the heat capacity of a small sample with a high precision. On the other hand, it is difficult to measure latent heat with AC calorimetry. The current status of its advantages and disadvantages is reviewed and the possible development of the method is discussed.

  • Photo-acoustic Method

    The characteristics, basic principle, experimental system and measured examples of a non-contact photo-acoustic method are introduced in order to measure the thermophysical properties of thin solid materials on the basis of my recent studies. The relation among light, heat and sound in relation to the photo-acoustic method is described briefly. The phase lag of the photo-acoustic signal for the incident modulated light expressed as a function of some properties such as the thermophysical properties of sample is derived from the RG (Rosencwaig and Gersho) theory. The thermal diffusivity of sample is obtained from the measured phase lag versus the modulated frequency of incident light, even if the thermophysical properties of backing material are unknown. The relation between the modulated frequency of incident light and the obtained vertical information of sample, and the analytical point in accordance with the transparency of sample for the incident light are also explained to some extent.

  • 3ω Method
    Simultaneous Measurements of Heat Capacity Spectroscopy and Dielectric Spectroscopy
    Hitoshi Kawaji, Takeo Tojo, Tooru Atake

    It is possible to perform the high frequency measurements of the frequency dependence of heat capacity using so-called 3ω method, in which a thin metal film is used as a heater and a thermometer. The method has been applied to heat capacity spectroscopy with a wide frequency range up to 10kHz. In this paper, the development of the system for simultaneous measurements of the heat capacity spectroscopy and dielectric susceptibility is reported. It is shown that the simultaneous measurements provide the useful information to investigate the correlation between the motions of the dipole moments and the enthalpy relaxation phenomena.

  • Temperature-Modulated DSC
    Akihiko Toda

    The method of temperature-modulated DSC is reviewed in terms of its applicability and valuable characteristics. This method is frequently employed as a convenient tool for the measurement of heat capacity and its relaxation phenomena. T-M DSC can differentiate processes sensitive to temperature modulation, and hence the application is also valuable for the separation of different processes taking place simultaneously and for the examination of kinetics of phase transitions and chemical reactions.

    Temperature wave analysis (TWA) is a technique to observe the phase shift and the amplitude decay of temperature wave which is generated by a. c. Joule heating and propagating in the thickness direction of specimen by using a sensitive temperature sensor with negligible heat capacity. In this study a new application method of TWA to obtain thermal conductivity of liquid with a probe sensor was introduced. The theoretical background and the experimental set-up were shown. Thermal property of liquid at 25°C by TWA was in good agreement with the literature value.

    Several e-mails were exchanged between Prof. Schick and I (YS) about our views of the periodic heating method. Prof. Schick has been working on the periodic heating method extensively and organized Lähnwitzseminar known as the leading conference in this field. I believe that the most suitable person gave contribution to this special issue. I hope that the readers will enjoy this discussion and I thank for the recent surprising development of the communication technology that enabled this discussion.
