: Conventional ac-calorimetry method could accurately measure the in-plane thermal diffusivity of suspended thin films but cannot be applied to small-scale samples due to the large sample size required by this method. This work proposes a novel optical-based ac-calorimetry method that circumvents the limitations of the conventional ac-calorimetry method. This new method uses a modulated continuous-wave laser to heat the sample periodically, and another continuous-wave laser to detect the sample’s temperature response on the surface at different distances from the heating spot via the principle of thermoreflectance. Since this method uses highly focused laser beams with micrometer-scale spot diameters for optical heating and temperature sensing, and this method uses the state-of-the-art thermal model of 3D anisotropic multilayers for signal processing, this method can accurately measure the in-plane thermal conductivity of suspended and supported thin films and bulk materials with sub-millimeter-scale lateral sizes, with a typical

: In view of China’s existing problems in the preservation and redevelopment of historical buildings in China, the concept of green rehabilitation of historical buildings is proposed, and its development process of is briefly summarized explaining the advantages and developmental necessities of green rehabilitation of historical buildings. From the perspective of WRS, the strength and weakness of the green rehabilitation of historical buildings in China currently, as well as external opportunities and threats, are sorted out. The AHP analysis is used to optimize the element structure of development. And it abstracts social consensus, professional technology, standard implementation system, financial support and social capital as the five core elements and their interaction in the development of green regeneration of historical buildings in China. Combined with the characteristics of five utilization types of Chinese historical buildings, this paper classifies and analyzes the corresponding important development factors, and further puts forward the corresponding development suggestions of two modes in combination with the cases of domestic historical buildings with better green regeneration.

: With the implementation of the national carbon neutralization and carbon peak strategy, the technology of shipping energy conservation and emission reduction has also been concerned by the public. As there are high-power engines and generator sets in the engine room of the ship, the waste heat temperature of waste gas generated during equipment operation is extremely high, which can be as high as thousands of degrees Celsius. The device first converts waste gas waste heat into mechanical energy through Stirling machine, and then converts it into electrical energy through external generator. The whole working process produces electric energy while reducing the ambient temperature, and improves the utilization efficiency of waste heat. According to the preliminary experiment, about 3.3v electric energy can be generated when the temperature is 433 °C . The device has simple structure, no complex mechanical structure, high safety and strong reliability. If multiple equipment can be used in the marine engine room at the same time, it will have a positive help to achieve the goals of carbon neutralization and carbon peak.
