Summary: Dielectric nanofluids, specifically SiO2 nanoparticle suspensions in mineral oil, have been investigated for their improved dielectric and thermal properties. The addition of nanoparticles leads to an enhancement in AC breakdown voltage and thermal conductivity, but it also results in a decrease in AC breakdown voltage and an increase in viscosity when the critical volume fraction is exceeded.

Summary: We present an approach combining multiple probe wavelengths' nanosecond transient thermoreflectance technique with a transient temperature rise model to study the linear relation between reflectance change and temperature change. This method enables fast and accurate determination of the temperature range and the thermoreflectance coefficient. Our findings show that the linear relationships of commonly used metal transducers may become nonlinear at elevated temperatures. This method provides a reliable platform to characterize thermoreflectance properties and understand the mechanism of thermoreflectance linear relationship.

Summary: This study investigated and modeled the effects of biochar particle size, biochar rate, and soil moisture content on the thermal properties of a sandy loam soil. The results showed that a higher biochar application rate significantly altered soil physical and chemical properties, while biochar particle sizes had a remarkable effect on soil thermal properties. Soil moisture had a more robust effect on thermal properties than biochar amendment. Mathematical models were able to estimate thermal conductivity, heat capacity, and thermal diffusivity accurately.

Summary: The experimental study showed that the incorporation of supplementary cementitious materials significantly affects the heat transfer properties of concrete, especially in NWC. The impact of different cement types on volume heat capacities was less significant in LWAC compared to NWC. Furthermore, optimizing the physical properties of fly ash and bottom ash from waste disposal can lead to LWAC with low heat conductivity and high compressive strength.

Summary: This study conducted in-situ thermal transport measurements on the newly discovered semiconductor crystal boron arsenide under high hydrostatic pressure and observed anomalous pressure dependence of the thermal conductivity. By using ultrafast optics, Raman spectroscopy, and inelastic X-ray scattering measurements, as well as atomistic theory calculations, the researchers revealed the mechanism behind this anomalous behavior and verified the accuracy of the theoretical calculations. The study also showed phonon dynamics beyond classical models, providing fundamental insights into microscopic energy transport in materials of extreme properties.

Summary: Recent studies on Co3Sn2S2 have mainly focused on its electrical and magnetic properties as a Weyl semimetal, half metal, and anisotropic ferromagnet. This study investigates the low-temperature thermal characteristics of Fe-doped Co3Sn2S2, including heat capacity, Seebeck coefficient, and thermal conductivity. The results show that Fe-doping affects the Debye temperature and density of states at the Fermi level, as well as increases the Seebeck coefficient and suppresses the thermal conductivity. The study also explores the influence of an external magnetic field on the Seebeck coefficient and thermal conductivity of pristine Co3Sn2S2.

Summary: The room-temperature thermal diffusivity of high T-c materials is dominated by phonons, allowing the scattering of phonons by electrons to be discerned. The temperature derivative of the resistivity of strongly overdoped cuprates shows a kink at a little below 200 K, which is argued to be the onset of a high-temperature Planckian T-linear scattering of electrons by classical phonons. This kink continuously disappears toward optimal doping, highlighting the lack of a feature in the T-linear resistivity at optimal doping associated with the onset of phonon scattering.

Summary: The temperature and thermal properties of shelf sediments from the East Siberian, Laptev, and Kara Seas were determined, revealing the widespread presence of subsea permafrost. The thermal conductivity of unfrozen cryotic sediments was predominantly influenced by the contents of silt and clay. Frozen sediments exhibited higher thermal conductivities, with salinity, ice content, and unfrozen water also playing roles in thermal conductivity.

Summary: In order to improve quality of life, people nowadays try to maintain internal spaces that are free from external environmental influences. This paper focuses on the application of thermal insulations, particularly the use of super insulation materials such as aerogel and vacuum insulation panels, to reduce heat loss in buildings. The researchers performed temperature-induced investigations on nanostructured graphite expanded polystyrene to study its thermal stability after long-term and short-term thermal annealing. The results reveal changes in thermal properties, structure, and surface of the material, as well as variations in thermal conductivity and compressive property induced by thermal annealing.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.

Summary: Demand-side management is crucial to smart energy systems. This paper proposes a data-driven approach to understand the relationship between energy consumption patterns and household characteristics for better DSM services. The proposed method uses a clustering algorithm to generate optimal customer groups for DSM and a deep learning model for training. The model can predict the possibility of DSM membership for a given household. The results demonstrate the usefulness of weekly energy consumption data and household socio-demographic information for distinguishing consumer groups and the potential for targeted DSM strategies.
