As a high-performance reinforcing material, carbon fiber (C f ) has a high anisotropy, so its distribution in the matrix has a significant impact on the Thermal conductivity (TC) of the Fe-based composite. In this study, TC in the radial direction of C f -Cu was corrected by the TC calculation...

The perovskite structure materials used as an oxygen ion conductor in solid oxide fuel cells have been widely studied. Here, we report novel property of NaNbO 3 -based ceramics about oxygen ion conduction. The grain size is significantly increased as well as the structural symmetry is enhanced...

Lead selenide (PbSe) is considered to be decent candidate replacing lead telluride (PbTe) as intermediate temperature (600-900 K) thermoelectric application due to its lower intrinsic lattice thermal conductivity, higher thermal stability, and larger abundance of Se than Te. To improve the...

This paper investigates the differential responses by managers to institutional investors during site visits and to retail investors during online Q&As. We find that the gap in firms' responses to different types of investors increases the potential for comment letters to be sent to firms and...

Based on the unique corporate ownership structure in China, we document that although firms tend to release corporate social responsibility (CSR) reports to convey that they are acting in the broader interests of society, those with inherently higher legitimacy (local government-owned firms) are...

Economic policy uncertainty relates to the complexity and unpredictability of the macroeconomic policy formulation process. Such uncertainty affects firm innovation. By constructing an innovation strategic option model, we find that economic policy uncertainty will have a negative influence on...
