Sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs) have been considered as attractive alternatives for next-generation battery systems, which have promising application potential due to their earth abundance of potassium and sodium, high capacity and suitable working potential, however, the design and application of bi-functional high-performance anode still remain a great challenge up to date. Bismuth sulfide is suitable as anode owing to its unique laminar structure with relatively large interlayer distance to accommodate larger radius ions, high theoretical capacity and high volumetric capacity etc. In this study, dandelion-like Bi_(2)S_(3)/rGO hierarchical microspheres as anode material for PIBs displayed reversible capacity, and 206.91 mAh·g^(−1) could be remained after 1,200 cycles at a current density of 100 mA·g^(−1). When applied as anode materials for SIBs, 300 mAh·g^(−1) could be retained after 300 cycles at 2 A·g^(−1) and its initial Coulombic efficiency is as high as 97.43%. Even at high current density of 10 A·g^(−1), 120.3 mAh·g^(−1) could be preserved after 3,400 cycles. The Na_(3)V_(2)(PO_(4))_(3)@rGO//Bi_(2)S_(3)/rGO sodium ion full cells were successfully assembled which displays stable performance after 60 cycles at 100 mA·g^(−1). The above results demonstrate that Bi2S3/rGO has application potential as high performance bi-functional anode for PIBs and SIBs.

A series of zinc oxide(ZnO) nano-/micro-rods had been synthesized via solution-based routes. In the hydrothermal route, the obtained ZnO nano-/micro-rods had two topographics. In refluxing procedures, spindly ZnO nanorods were obtained in the presence of poly(vinyl-pyrrolidone)(PVP) and ellipsoid-like nanorods were obtained in the absence of PVP. The products were characterized using X-ray powder diffraction(XRD),scanning electron microscope(SEM), transmission electron microscope(TEM), and electron diffraction(ED)analysis. Room temperature photoluminescence(PL)spectra of the ZnO products demonstrated a weak UV emission and a broad visible emission for each of the sample. The growth mechanism of 1-D ZnO crystals was discussed briefly.

A Hoffa fracture is an uncommon clinical entity typically seen in adults after high-energy trauma. Nonunion ofa Hoffa fracture appears to be even more uncommon. To our knowledge, only three cases of nonunion ofa Hoffa fracture have been documented in the literature to date, including two children and one adult. This article presents a case of an adult who had nonunion of a Hoffa fracture for 27 years and was treated by open reduction and internal fixation, and the varus deformity corrected with xenogenous bone graft. An excellent result has been achieved to date. This unusual case reminds us that we cannot neglect the possibility of nonunion of a cancellous hone fracture, especially the Hoffa fractures of the medial femoral condyle if they are treated nonoperatively. It also demonstrates that internal fixation with bone graft is effective, even for the 27-year Hoffa fracture.

出口信用保险项下的贸易融资可以实现出口企业、保险公司、银行三方共赢,但近年来出现了信息不对称状况恶化、银行融资政策收紧、业务规模下滑等问题。现行机制下,保险公司的加入并未缓解传统信贷关系中银行与融资企业之间的信息不对称状态,反而滋生了新的逆向选择和道德风险。通过三方博弈分析可知,出口企业出于"理性"会选择不诚信行为,甚至与保险公司合谋骗取银行融资,特别是在银行管控无效的情况下。基于博弈过程及均衡结果,认为出口企业应积极向银行和保险公司传递降低信息不对称的信号,保险公司制度设计上要建立与银行的风险信息共享与有效互动合作机制,银行应加强对出口企业贷前贷中贷后的全过程风险管控。
