Summary: This study compares the thermomechanical behavior of different materials under accelerated ageing conditions, including insulation materials using recycled rubber and other comparison materials. Among them, aerogel-based materials showed superinsulation behavior and good flexibility, while extruded polystyrene exhibited permanent deformation under compression. In general, ageing conditions led to a slight increase in thermal conductivity, which disappeared after drying of the samples in an oven, and a decrease in Young's moduli.

Summary: The multicomponent rare-earth cerate (Y0.2La0.2Nd0.2Sm0.2Eu0.2)(2)Ce2O7 ceramics with a single-phase fluorite-type crystal structure were successfully synthesized. The ceramics exhibited lower thermal conductivity, higher thermal expansion coefficients, and excellent mechanical properties. These properties make them suitable for potential applications in next-generation thermal barrier coatings.

Summary: Ceramic materials in thermal barrier coatings tend to sinter during long-term service, leading to performance deterioration at high temperatures. In this study, thermal exposure experiments were conducted on the NdYbZr2O7 coating at 1300 degrees C. Results showed that multipoint connection was the predominant sintering mechanism. The sintering process was divided into two stages based on porosity evolution. The NdYbZr2O7 coating demonstrated better thermal insulation and higher sintering resistance compared to other coatings reported in previous literature.

Summary: This study investigates the effects of annealing on the properties of Buckypapers, showing that annealing improves the quality of carbon nanotubes and leads to increased Young's modulus, electrical conductivity, and thermal conductivity of BPs. The enhancements in conductivity are attributed to the enhancement of inter-tube contact after annealing.

Summary: This study presents an approach to synthesizing a mathematical model for determining the composition of geopolymer foams. The focus is on improving the accuracy of multi-criteria optimization for metakaolin-based geopolymer composite composition. The proposed model combines various mathematical models and methods to optimize the composition of foamed geopolymers, resulting in improved mechanical, thermal, and technological properties.

Summary: This study investigated the impacts of cracks in TBCs on temperature field, heat flux distribution, thermal and mechanical properties using numerical reconstruction models and thermal lattice Boltzmann method. The results showed that the effective thermal conductivity and Young's modulus decrease with the increase of crack length and opening. The energy release rate increases faster for small cracks and slows with crack growth, with crack opening further enhancing the energy release rate.

Summary: This study proposes a strategy of codoping solid fillers and liquid metal fillers into polymer substrates to overcome the dilemma of thermal-mechanical properties of thermal interface materials. Through the synergistic effect of the solid fillers and liquid metal fillers, the thermal conductivity can be improved and Young's modulus can be kept small simultaneously. The experimental results demonstrate the stable physical performance of the developed material.

Summary: This paper presents an experimental study on the thermo-mechanical properties of talcum-based steatite ceramics with artificially introduced porosity using an organic pore-forming agent. The material parameters are represented by homogenization schemes from effective medium/effective field theory. The thermal conductivity and elastic properties exhibit a linear relationship with porosity, while the strength properties show a higher-order power-law dependency due to the localization of the failure mechanism in the quasi-brittle material.

Summary: In this study, first-principles calculations were performed to investigate the thermal-mechanical properties of LnTa(2)O(6) ceramics. The results showed that LnTa(2)O(6) has excellent fracture toughness and thermal conductivity, lower Young's modulus and comparable hardness compared to YSZ. These characteristics make LnTa(2)O(6) ceramics a promising material for next-generation turbine engines.

Summary: In this study, wave-selective emitter coolers were fabricated using glass bubbles and barium sulfate, and polyacrylonitrile nanofibers were electrospun on these coolers. The optical properties and cooling power were analyzed based on the ratio of glass bubbles and barium sulfate, as well as the electrospinning conditions. The cooler with the added electrospinning layer showed higher reflectivity and cooling power compared to the cooler containing only polydimethylsiloxane/glass bubbles and barium sulfate. This study improves the performance of previously studied passive radiative cooling.

Summary: This study evaluated the thermal and mechanical properties of nanoscale amorphous silicon carbide thin films using the femtosecond pump-probe technique. The results showed that the thermal conductivity of the films was lower than bulk crystalline SiC, and a decrease in mass density resulted in a reduced Young's modulus. The scale effect on these properties was not significant.

Summary: This study investigates the differences in effective thermal conductivity and Young's modulus between strut-based and surface-based unit cell geometries, and examines the impact of material distribution on these properties. It is found that material distribution on the unit cell wall improves thermal conductivity and Young's modulus, while a narrow cross-sectional area reduces these properties.

Summary: Open-cell metamaterials prepared by additive manufacturing or replica techniques may have processing defects such as limited resolution, strut cross-section variations or internal strut porosity, leading to deviations from the ideal microstructures and properties. This study quantitatively investigates these effects and finds that porosity, resolution, and strut thinning all have significant impacts on the material's thermal conductivity and elastic constants.

Summary: This study investigates the relationship between morphological characteristics and mechanical stimuli in the human mesenchymal stem cell (hMSC) constructed biohybrid surfaces of nitrogen and zirconia composites. The results showed that these biohybrid materials have high tolerance to mechanical stimuli and blood flow, which explains why there are various degrees of peripheral mechanical deformation in the in vitro baseline properties of this biological sponge. When mechanical stimuli were applied to the sediment of cultured hMSCs, the trend of pseudobone stimulation became more apparent.

Summary: This study investigates the stabilization of oil/water emulsions with the addition of a biopolymer (scleroglucan) by analyzing rheological properties and visualizing interactions through cryo transmission electron microscopy. The results suggest that the concentration of scleroglucan and its interactions with surfactants play a crucial role in emulsion stabilization.
