A double-layered protective film based on zinc-based coordination compound and ZnF2-rich solid electrolyte interphase layer has been successfully fabricated on the zinc metal anode via electrode/electrolyte synergistic *** double-layered architecture can effectively modulate Zn2+ flux and suppress the zinc dendrite growth, thus facilitating the uniform zinc *** as-developed zinc-(dual) halogen batteries based on double-layered protective film can present high areal capacity and satisfactory cycling stability. Aqueous zinc-halogen batteries are promising candidates for large-scale energy storage due to their abundant resources, intrinsic safety, and high theoretical capacity. Nevertheless, the uncontrollable zinc dendrite growth and spontaneous shuttle effect of active species have prohibited their practical implementation. Herein, a double-layered protective film based on zinc-ethylenediamine tetramethylene phosphonic acid (ZEA) artificial film and ZnF2-rich solid electrolyte interphase (SEI) layer has been successfully fabricated on the zinc metal anode via electrode/electrolyte synergistic optimization. The ZEA-based artificial film shows strong affinity for the ZnF2-rich SEI layer, therefore effectively suppressing the SEI breakage and facilitating the construction of double-layered protective film on the zinc metal anode. Such double-layered architecture not only modulates Zn2+ flux and suppresses the zinc dendrite growth, but also blocks the direct contact between the metal anode and electrolyte, thus mitigating the corrosion from the active species. When employing optimized metal anodes and electrolytes, the as-developed zinc-(dual) halogen batteries present high areal capacity and satisfactory cycling stability. This work provides a new avenue for developing aqueous zinc-(dual) halogen batteries.

Mooring system failure can lead to largely different dynamic response of floating structures when compared to the response under the condition of intact mooring *** a semi-submersible platform with taut mooring system under extreme environmental conditions,the typical mooring system failure includes anchor line breaking failure due to the broken anchor line,and the anchor dragging failure caused by the anchor failure in the seabed soil due to the shortage of the anchor bearing ***,study on the mooring failure caused by anchor failure is *** current work investigates the effect of three failure modes of taut mooring system on dynamic response of a semi-submersible platform,including one line breaking failure,two lines breaking failure,and one line breaking with one line attached anchor dragging *** nonlinear polynomial mooring line model in AQWA was used with integrating the load and displacement curve from the anchor pulling study to characterize the anchor dragging behavior for mooring system failure caused by the anchor *** offsets of the platform and the tension of mooring lines were analyzed for mooring system failure with 100-year return *** is found that the mooring failure of one line breaking with one line attached anchor dragging is a case between the other two mooring *** traditional mooring analysis considering only the damaged condition with one line breaking is not safe *** the simple way of mooring analysis of two lines breaking is too conservative for the costly offshore engineering.

目的探讨透明角膜切口白内障超声乳化术对角膜波前像差的影响。方法方便选取2016年3—10月该院收治的150例(162眼)年龄相关性白内障患者为研究对象,全部患者均行白内障超声乳化术,依据切口位置不同分为实验组(最大角膜屈光度子午线方位透明角膜切口,100例112眼)和对照组(135度方位透明角膜切口,50例50眼)。对比观察两组最佳矫正视力及治疗前后角膜散光量和波前像差。结果实验组术后8周最佳矫正logMAR视力(0.044±0.05)与对照组差异无统计学意义(t=0.106,P>0.05);实验组术后8周角膜散光量(0.53±0.42)D与对照组比较差异有统计学意义(t=4.290,P<0.05);实验组术后1周角膜球差(0.17±0.13)μm与术前比较差异有统计学意义(t=3.410,P<0.05)。结论白内障超声乳化手术采用最大角膜屈光度子午线方位透明角膜切口有助于减少术后角膜散光,但可引起术后早期角膜波前像差改变,后经康复可基本恢复至术前水平。
