摘要：It is a great challenge to finely tune the morphology of iron oxides for energy storage. In this work, we introduced a facile hydrothermal method to obtain single crystalline hematite （α-Fe2O3） nano-coffee beans （NCBs） with the assistance of acetic acid. Interestingly, α-Fe2O3 nanos- tructures with this special morphology were formed under the effect of Ostwald ripening and oriented etching of H^＋ ions along [001] direction, which could be proved by the scanning electron microscope/transmission electron microscope and X-ray diffraction. After calcination at high temperature, the as-prepared α-Fe2O3 NCBs were used as potential anode ma- terials, showing a very high reversible capacity of 810 mA h g^-1 （0.2 C）, excellent cycling stability, and high-rate performance for lithium storage. Hence, in virtue of the good performances, the structural design of nanomaterials would be promoted in the fabrication of electrode materials for lithiumion batteries.

摘要：Projections of potential submerged area due to sea level rise are helpful for improving understanding of the influence of ongoing global warming on coastal areas. The Ensemble Empirical Mode Decomposition method is used to adaptively decompose the sea level time series in order to extract the secular trend component. Then the linear relationship between the global mean sea level （GMSL） change and the Zhujiang （Pearl） River Delta （PRD） sea level change is calculated： an increase of 1.0 m in the GMSL corresponds to a 1.3 m （uncertainty interval from 1.25 to 1.46 m） increase in the PRD. Based on this relationship and the GMSL rise projected by the Coupled Model Intercomparison Project Phase 5 under three greenhouse gas emission scenarios （representative concentration pathways, or RCPs, from low to high emission scenarios RCP2.6, RCP4.5, and RCP8.5）, the PRD sea level is calculated and projected for the period 2006-2100. By around the year 2050, the PRD sea level will rise 0.29 （0.21 to 0.40） m under RCP2.6, 0.31 （0.22 to 0.42） m under RCP4.5, and 0.34 （0.25 to 0.46） m under RCP8.5, respectively. By 2100, it will rise 0.59 （0.36 to 0.88） m, 0.71 （0.47 to 1.02） m, and 1.0 （0.68 to 1.41） m, respectively. In addition, considering the extreme value of relative sea level due to land subsidence （i.e., 0.20 m） and that obtained from intermonthly variability （i.e., 0.33 m）, the PRD sea level will rise 1.94 m by the year 2100 under the RCP8.5 scenario with the upper uncertainty level （i.e., 1.41 m）. Accordingly, the potential submerged area is 8.57x103 km2 for the PRD, about 1.3 times its present area.

摘要：钙钛矿太阳能电池的表界面性质是影响器件效率和稳定性的关键性因素.本文中,我们首次发现空穴传输层中的添加剂4-叔丁基吡啶(tBP)可以将钙钛矿非晶态和缺陷表面层进行重结晶,并且钝化晶粒表面的缺陷位点.该重构可使钙钛矿的表面功函数增大,降低了钙钛矿与空穴传输层之间的界面能级失配,提高了器件的光电压.进一步地,我们通过化学键合强度设计,开发了更有效的空穴传输层添加剂4-叔丁基哌啶(tBPp),它比tBP具有与钙钛矿表面缺陷位点更强的相互作用.得益于吸附能的增强,经tBPp重构的钙钛矿表面缺陷态密度降低,且在热、光、湿度的作用下稳定性更好.基于tBPp作为添加剂的钙钛矿电池最高效率达到了24.2%.在氮气气氛中进行最大功率点跟踪测试,未封装的设备在连续光照超过1200小时后几乎可以保持其初始效率.本工作全面揭示了空穴传输层中添加剂对于钙钛矿电池的效率和稳定性的重要性,并提供了系统和基础性理解.
