TL;DR: In this article, Li et al. demonstrated the preparation and application of porous LiMn2O4 nanorods as cathode materials for rechargeable lithium-ion batteries, which exhibited superior high-rate capability and cyclability to the counterpart nonporous nanorod and nanoparticles.
Abstract: In this paper, we demonstrated the preparation and application of porous LiMn2O4 nanorods as cathode materials for rechargeable lithium-ion batteries. Solid-state lithiation of porous Mn2O3 nanorods, resulting from thermal decomposition of MnC2O4 precursor, led to the formation of porous LiMn2O4 nanorods with high crystallinity and phase purity. Without surface modification, the as-synthesized porous nanorods exhibited superior high-rate capability and cyclability to the counterpart nonporous nanorods and nanoparticles. An initial discharge capacity of 105 mAh g−1 could be delivered at 10 C rate, and capacity retention of about 90% was obtained after 500 cycles at this high rate. The durable high-rate capability was attributed to the unique porous one-dimensional (1D) nanostructure that gave rise to fast Li-intercalation kinetics and good structural stability for the spinel electrodes. The beneficial gains from 1D porous nanoarchitecture may enlighten the design and construction of new spinel-based electrode for high power applications.

TL;DR: It was found that the crystallinity of the catalysts played an important role on their degradation capacity to Bisphenol A (BPA), and Bi2WO6 catalyst showed the highest photocatalytic activity to degrade BPA under simulated solar light irradiation.
Abstract: Bismuth tungstate (Bi2WO6) catalysts of different morphology were synthesized with a hydrothermal method by controlling the pH of the reaction solution. The properties of the synthesized catalysts were characterized and all catalysts presented high photoabsorption capacity in the range of UV light to visible light around 450 nm. The surface area of the catalysts decreased but the crystallinity increased with the pH of the hydrothermal reaction solution in the range of 4−11. It was found that the crystallinity of the catalysts played an important role on their degradation capacity to Bisphenol A (BPA). Bi2WO6 catalyst prepared at pH 11 displayed a mesoporous structure and it showed the highest photocatalytic activity to degrade BPA under simulated solar light irradiation. Nearly 100% of BPA with original concentration at 20 ppm was removed after 30 min irradiation in a solution with pH 10 and Bi2WO6 amount of 1.0 g L−1. Furthermore, 86.6 and 99.1% of the total organic carbon was eliminated after 60 and 120...

TL;DR: It is reported that domain boundaries in the basal plane of monolayer MoS2 can greatly enhance its hydrogen evolution reaction performance by serving as active sites, and it is demonstrated that such superior catalysts are feasible at a large scale by applying this multi-hierarchy design of domain boundaries to wafer-scale MonS2 films.
Abstract: Recently, monolayer molybdenum disulphide (MoS2) has emerged as a promising and non-precious electrocatalyst for hydrogen evolution reaction. However, its performance is largely limited by the low density and poor reactivity of active sites within its basal plane. Here, we report that domain boundaries in the basal plane of monolayer MoS2 can greatly enhance its hydrogen evolution reaction performance by serving as active sites. Two types of effective domain boundaries, the 2H-2H domain boundaries and the 2H-1T phase boundaries, were investigated. Superior hydrogen evolution reaction catalytic activity, long-term stability and universality in both acidic and alkaline conditions were achieved based on a multi-hierarchy design of these two types of domain boundaries. We further demonstrate that such superior catalysts are feasible at a large scale by applying this multi-hierarchy design of domain boundaries to wafer-scale monolayer MoS2 films.

TL;DR: Wang et al. as mentioned in this paper explored a comprehensive set of board characteristics (size, composition and functioning of the board) and analyzed their impacts on bank performance and bank asset quality in China.
Abstract: Using a sample of 50 largest Chinese banks during the period of 2003–2010, we explore a comprehensive set of board characteristics (size, composition and functioning of the board) and analyze their impacts on bank performance and bank asset quality in China. We find that the number of board meetings and the proportion of independent directors have significantly positive impacts on both bank performance and asset quality while board size has a significantly negative impact on bank performance. We find new evidence that the degree of bank boards’ political connection is negatively correlated with bank performance and asset quality. The findings suggest that the board of directors plays a significant role in bank governance in China.
