Abstract
In this study, we enhanced the flexural strength of cordierite ceramics by incorporating h-BN (hexagonal boron nitride) nanoparticles, facilitated by the slip casting process. Initially, commercial cordierite powder with an average particle size of 10 mm underwent a ball-milling process to reduce the size to 2.5 mm and simultaneously achieve..... More

Abstract
Herein we report the optimized processing conditions of hot extrusion for fabricating an n-type Bi₂Te_2.7Se_0.3 thermoelectric compound, with high electronic transport properties as well as improved mechanical reliability. We fabricated a Bi₂Te_2.7Se_0.3 extrudate that was 3.8 mm in diameter and 700 mm in length by controlling the processing parameters of..... More

Abstract
La/Ce-partially double-filled and Co-charge-compensated (La_1−zCe_z)_0.8Fe_4−xCo_xSb₁₂ skutterudites were synthesized, and their thermoelectric properties were studied by varying the filling ratio and charge compensation. X-ray diffraction analysis revealed that the matrix phase was skutterudite and a secondary phase was determined to the marcasite FeSb₂. However, the formation of marcasite could be inhibited.....

Abstract
Assuming that many of the materials produced in a non-equilibrium state remain unchanged, an extended space–energy conservation law was proposed based on the existing energy conservation law. In the present study, by analyzing the well developed equilibrium binary phase diagram of iron (Fe) – carbon (C), we show that energy..... More
