“…Combined with the measured density and thermal diffusion coefficients, the thermal conductivity of the sample can be calculated as:

\begin{equation} \lambda = \rho \alpha C, \end{equation}

where λ is the thermal conductivity, ρ is the density, α is the thermal diffusion coefficient, and C is the heat capacity. Due to the anisotropy caused by the layered microstructure, the thermal conductivity of the sample along the out‐of‐plane direction and the in‐plane direction is different 14 . Figure 7C shows the thermal conductivity in the out‐of‐plane direction and the in‐plane direction.…”

“…The polymer‐induced mineral growth combined with the layer‐by‐layer deposition of calcium carbonate in porous organic films was used to prepare the nacre‐like material. In our earlier study, 14 a glass microflake‐gelatin nacre‐like material with a “brick‐wall” microstructure was prepared, the glass‐microflakes were well aligned by applying an applied electric field, and the resulting composites showed promising thermal, electrical, and mechanical properties.…”

Natural nacre has attracted a lot of attention due to its superior mechanical properties. It is generally made up of 95% flake calcium carbonate and 5% organic matter. In this work, we prepared the bionic nacre material using the “freezing‐mineralization” method. The bionic material exhibits a microstructure that is quite similar to that of natural material and shows a high dielectric constant. The thermal conductivity in the in‐plane direction reaches 1.15 W/(m•K) at ambient temperature, which is 2.25 times higher than the out‐of‐plane direction's, clearly demonstrating an anisotropic behavior. Additionally, the mechanical performance of the biomimetic material can be on par with that of natural materials with a maximum breakdown stress of 51.4 MPa. Our results prove that the “freezing‐mineralization” method is essential to developing bionic nacre materials.

The effects of fluxes with different activators (sebacic acid and diethylamine hydrochlcoride) on the wetting behavior of Sn-Zn lead-free solders were investigated. The wettability tests showed that fluxes with the addition of single sebacic acid or diethylamine hydrochlcoride significantly improved wettability of Sn-Zn solder on Cu substrate. However, fluxes with combined additions of above activators promoted wetting performance of the solder further. Thermal analysis (thermal-gravimetry analyzer and differential scanning calorimeter) results demonstrated that the effective temperature range of diethylamine hydrochlcoride is higher than that of sebacic acid. So diethylamine hydrochlcoride could react with oxides on the solder and substrate surfaces at a wider temperature range which resulted in an enhanced spreading of solders. Scanning electron microscopy (SEM) image showed that two kinds of diffusion layers were formed between Sn-Zn solder and Cu substrate, indicating fluxes with binary activators markedly improved welding quality of Sn-Zn solder.
