Concentric Cylinders

A method is presented for calculating the conductive heat transfer through gases contained between two concentric cylinders. The method of Lees and Liu is extended to include incomplete thermal accommodation at the inner cylindrical surface, and a comparison is made between the two methods. These results are then compared to those of the low pressure and temperature jump methods. On the basis of this analysis, limits are obtained for the free-molecule, transition, temperature jump, and continuum regimes.

Lanthanum Boride

This study utilizes accurate first principle method to conduct a comparative study on he electronic structure of multiple borides. State density of the borides is also summarized. It is found that lanthanum boride has special electronic structure characteristics. Therefore, it is presumed that there is high superconducting transition temperature (Tc) in lanthanum boride. This study is able to provide asignificant theoretical reference for further experimental research.
