1Abdominal applications of diffusion-weighted magnetic resonance imaging: Where do we stand?显示文摘Diffusion-weighted imaging (DWI) is one of the magnetic resonance imaging (MRI) sequences providing qualitative as well as quantitative information at a cellular level. It has been widely used for various applications in the central nervous system. Over the past decade, various extracranial applications of DWI have been increasingly explored, as it may detect changes even before signal alterations or morphological abnormalities become apparent on other pulse sequences. Initial results from abdominal MRI applications are promising, particularly in oncological settings and for the detection of abscesses. The purpose of this article is to describe the clinically relevant basic concepts of DWI, techniques to perform abdominal DWI, its analysis and applications in abdominal visceral MR imaging, in addition to a brief overview of whole body DWI MRI.Ajaykumar C Morani Khaled M Elsayes Peter S Liu William J Weadock Janio Szklaruk Jonathan Russell Dillman Asra Khan Thomas L Chenevert Hero K Hussain 2013World Journal of Radiology2013,5,3:12
211.2% Efficiency all-polymer solar cells with high open-circuit voltage显示文摘Herein,we fabricated all-polymer solar cells(all-PSCs)based on a fluorinated wide-bandgap p-type conjugated polymer PM6 as the donor,and a narrow bandgap n-type conjugated polymer PZ1 as the acceptor.In addition to the complementary absorption and matching energy levels,the optimized blend films possess high cystallinity,predominantly face-on stacking,and a suitable phase separated morphology.With this active layer,the devices exhibited a high Vocof 0.96 V,a superior Jscof 17.1 mA cm^-2,a fine fill factor(FF)of 68.2%,and thus an excellent power conversion efficiency(PCE)of 11.2%,which is the highest value reported to date for single-junction all-PSCs.Furthermore,the devices showed good storage stability.After 80 d of storage in the N2-filled glovebox,the PCE still remained over 90%of the original value.Large-area devices(1.1 cm^2)also demonstrated an outstanding performance with a PCE of 9.2%,among the highest values for the reported large-area all-PSCs.These results indicate that the PM6:PZ1 blend is a promising candidate for scale-up production of large area high-performance all-PSCs.Yuan Meng Jingnan Wu Xia Guo Wenyan Su Lei Zhu Jin Fang Zhi-Guo Zhang Feng Liu Maojie Zhang Thomas P.

4优化快速成膜工艺中的前驱体组分以制备致密、稳定的钙钛矿薄膜(英文)显示文摘快速成膜工艺提供了一种简单、高产率、无铅释放的钙钛矿薄膜制备方法.在这一方法中,低浓度的钙钛矿前驱体溶液被滴到240℃的热衬底上,伴随着溶剂在高温条件下的迅速挥发,钙钛矿在衬底表面迅速结晶,生长成一层薄膜.在此过程中,所有含铅的原材料都被沉积到钙钛矿薄膜中,含铅原材料的浪费和铅释放导致的污染都被显著降低.这种方法制备的钙钛矿薄膜的性质可以由前驱体溶液的组分调节.CH_3NH_3Cl(MACl)可以调节结晶过程,有助于提高薄膜表面覆盖率.CH(NH_2)_2I(FAI)有助于提高钙钛矿薄膜的热稳定性.当前驱体组分为PbI_2·(1-x)FAI·xMACl,x=0.75时,快速成膜工艺制备的钙钛矿膜达到最优化性质,由此制备的平面结太阳电池可以实现超过15%的能量转换效率,迟滞现象很小,并且重复性良好.刘堂昊 周圆圆 胡芹 陈科 张翼飞 杨文强 吴疆 叶冯俊 罗德映 朱凯 Nitin P.Padture 刘锋 Thomas Russell 朱瑞 龚旗煌 2017Science China Materials2017,60,7:4

7High-efficiency quaternary polymer solar cells enabled with binary fullerene additives to reduce nonfullerene acceptor optical band gap and improve carriers transport显示文摘The polymer/small-molecule electron donor and nonfullerene organic electron acceptor are of structural similarity with both donor and acceptor molecules consisting of polycyclic fused-ring backbone and being decorated with alkyl-chains.In this study,we report that the introduction of binary fullerenes(C_(60)-/C_(70)-PCBM and C_(60)-/C_(70)-ICBA)into a nonfullerene binary system PBDB-T:ITIC reduces the polymer-nonfullerene acceptor intermixing,obtaining higher crystallinity with(100)crystal coherence length from 28 to 29–33 nm for the ITIC,and from 14 to 20–24 nm for the PBDB-T,and improved electron and hole mobilities both.Unprecedentedly,such a protocol reduces the ITIC optical band gap from 1.59 to 1.55 eV.As consequences,higher short-circuit current-density(17.8–18.4 vs.15.8 m A/cm^2),open-circuit voltage(0.92 vs.0.90 V)and fill-factor(0.72–0.73 vs.0.68)are simultaneously obtained,which ultimately afford higher efficient quaternary polymer solar cells with power conversion efficiencies(PCEs)up to 12.0%–12.8%comparing to the host binary device with 9.9%efficiency.For the polymer,ITIC,and ICBA/PCBM ternary blends,11%PCEs were recorded.The use of PCBM leads to larger red-shifting in thin film absorption and external quantum efficiency(EQE)response.Such effect is more pronounced when ICBA:PCBM mixture is used.These results indicate the size and shape of C_(60)and C_(70)as well as the substituent position of the second indene unit on C_(60)-/C_(70)-ICBA affect not only the blend morphology but also the electronic coupling in BHJ mixtures:the quaternary device performance increased in sequences of C_(70)-PCBM:C_(70)-ICBA→C_(70)-PCBM:C_(60)-ICBA→C_(60)-PCBM:C_(70)-ICBA→C_(60)-PCBM:C_(60)-ICBA.The resonant soft X-ray scattering(RSoXS)data indicated the most refined phase separation in the C_(60)-PCBM:C_(60)-ICBA based blend,corresponding to its best device function among the quaternary devices.These results indicate that the using of binary fullerenes as the acceptor additives allows for tuning nonfullerene blended film’s optical properties and filmmorphologies,shedding light on the designing high-performance multi-acceptor polymer solar cells.Weiping Li Dong Yan Feng Liu Thomas Russell Chuanlang Zhan Jiannian Yao 2018Science China Chemistry2018,61,12:2
