Limited empirical investigation has been devoted to understanding the multipleeffect mechanisms of moral leadership, especially the relationship between mediators. Drawing from both social learning and social exchange theories, this study examines whether value congruenee and leader-member exchange (LMX) mediate the effect of moral leadership on followers' positive work behaviors. Using two-wave survey data from 395 Chinese employees, the results indicate that both value congruence and LMX act as mediators in the relationship between moral leadership and positive work behaviors. Furthermore, a sequential mediation link from moral leadership to value congruenee, then to LMX, and finally to positive work behaviors was established. Theoretical and practical implications are further discussed. 展开更多

The multiferroicity in the RMn2O5 family remains unclear, and less attention has been paid to its dependence on high-temperature(high-T) polarized configuration. Moreover, no consensus on the high-T space group symmetry has been reached so far. In view of this consideration, one may argue that the multiferroicity of RMn2O5 in the low-T range depends on the poling sequence starting far above the multiferroic ordering temperature. In this work, we investigate in detail the variation of magnetically induced electric polarization in GdMn2O5 and its dependence on electric field poling routine in the high-T range. It is revealed that the multiferroicity does exhibit qualitatively different behaviors if the high-T poling routine changes, indicating the close correlation with the possible high-T polarized state. These emergent phenomena may be qualitatively explained by the co-existence of two low-T polarization components, a scenario that was proposed earlier.One is the component associated with the Mn3+–Mn4+–Mn3+ exchange striction that seems to be tightly clamped by the high-T polarized state, and the other is the component associated with the Gd Mn3+–Mn4+–Mn3+ exchange striction that is free of the clamping. The present findings may offer a different scheme for the electric control of the multiferroicity in RMn2O5. 展开更多

The electrode Pt-loading has an effect on the number of active sites and the thickness of catalyst layer,which has huge influence on the mass transfer and water management during dynamic process in PEMFCs. In this study, membrane electrode assemblies with different Pt-loadings were prepared, and PEMFCs were assembled using those membrane electrode assemblies with traditional solid plate and water transport plate as cathode flow-field plates, respectively. The performance and electrochemical surface area of cells were characterized to evaluate the membrane electrode assemblies degradation after rapid currentvariation cycles. Scanning electron microscope and transmission electron microscope were used to investigate the decay of catalyst layers and Pt/C catalyst. With the increase of Pt-loading, the performance degradation of membrane electrode assemblies will be mitigated. But higher Pt-loading means thicker catalyst layer, which leads to a longer pathway of mass transfer, and it may result in carbon material corrosion in membrane electrode assemblies. The decay of Pt/C catalyst in cathode is mainly caused by the corrosion of carbon support, and the degradation of anode Pt/C catalyst is a consequence of migration and aggregation of Pt particles. And using water transport plate is beneficial to alleviating the age of cathode Pt/C catalyst. 展开更多

LCO2(liquid CO2)can absorb heat and release latent heat via phase transition,which can provide considerable cooling energy and effectively solve the problem of thermal damage in deep coal mining processes.A LCO2 cycle refrigeration system is designed to continuously cool down the working face in a mine,and CO2 is cyclically utilized.Additionally,LCO2 is used not only as a cold source but also to prevent spontaneous combustion of coal in the gob.COMSOL Multiphysics simulation software is used to characterize the thermal performance of the heat exchange system,where the heat transfers between the CO2 and the airflow.For a LCO2 consumption of 13.54 m^3/h,the temperature of the airflow in the tunnel decreases by 7.72℃,and the cooling volume of the system reaches 142.99 kW/h;the cooling volume provides a latent heat release of 46.68 kW/h.The main influencing factors of the refrigeration system,such as ventilation flux,LCO2 flow,LCO2 temperature and initial tunnel temperature,are also analyzed quantitatively through the software.The temperature of the steady airflow in the tunnel is proportional to the square of the local fan ventilation flux,and it decreases linearly with an increase in the LCO2 flow but increases with both the temperature of the LCO2 and the initial temperature in the tunnel.When the temperature difference between the LCO2 and wind increases,the heat exchange between the CO2 and wind intensifies,and the cooling volume increases. 展开更多

We report a strong antiferromagnetic(AFM) interlayer coupling in ferromagnetic La0.67Sr0.33MnO3/SrRuO3(LSMO/SRO) superlattices grown on(111)-oriented SrTiO3 substrate. Unlike the(001) superlattices for which the spin alignment between LSMO and SRO is antiparallel in the in-plane direction and parallel in the out-of-plane direction, the antiparallel alignment is observed along both the in-plane and out-of-plane directions in the present sample. The low temperature hysteresis loop demonstrates two-step magnetic processes, indicating the coexistence of magnetically soft and hard components. Moreover, an inverted hysteresis loop was observed. Exchange bias tuned by the temperature and cooling field was also investigated, and positive as well as negative exchange bias was observed at the same temperature with the variation of the cooling field. A very large exchange field(HEB) was observed and both magnitude and sign of the HEBdepend on the cooling field, which can be attributed to an interplay of Zeeman energy and AFM coupling energy at the interfaces. The present work shows the great potential of tuning a spin texture through interfacial engineering for the complex oxides whose spin state is jointly determined by strongly competing mechanisms. 展开更多

Thurston [J. Amer. Math. Soc., 1988, 1(3): 647 681] studied the diameter of the associahedron, which is the polytope arising from a marked disc by flips of triangulations. They showed that every shortest path between two vertices in a face does not leave that face. We give a new method, which is different from the one used by V. Disarlo and H. Parlier [arXiv: 1411.4285] to establish the same non-leaving-face property for all unpunctured marked surfaces. 展开更多
