Exploring high-performance environmental barrier coatings for rare earth silicates: A combined approach of first principles calculations and machine learning
Published 2025-05-01“…It follows that a combined approach of first principles calculations and machine learning is proposed for this problem, with establishing a comprehensive database comprising β-, γ- and δ-RE2Si2O7 (RE = La–Lu, Y, Sc) and correlating their mechanical/thermal properties on structural characteristics. It is revealed the [O3SiOSiO3] structure and polyhedron distortion affect mechanical properties of RE2Si2O7, while criteria for selecting RE2Si2O7 with low thermal conductivity are identified, including complex crystal structures, chemical bond inhomogeneity, and strong non-harmonic lattice vibrations. …”

Representative elementary volume determination and heat conduction simulation for porous geomaterials based on CT images
Published 2025-04-01“…The results indicate that: (1) the porosity REV is approximately the same size as the thermal conductivity REV; (2) the pore structure of artificial foamed concrete is relatively organized than that of natural sandstone; (3) orders of magnitude discrepancy in thermal conductivity of solid/fluid components and complex pore/particle structure have significant effect on the temperature distribution during heat conduction, which in turn leads to convergence, divergency and turning of conduction heat flow, finally causing variation of the macroscopic effective thermal conductivity (ETC) and resulting in complexity of related research efforts on the prediction of the ETC of tanglesome geomaterimals.…”
