1Inverted polymer solar cells with a solution-processed zinc oxide thin film as an electron collection layer显示文摘A solution-processed zinc oxide (ZnO) thin film as an electron collection layer for polymer solar cells (PSCs) with an inverted device structure was investigated. Power conversion efficiencies (PCEs) of PSCs made with a blend of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C61-butyric acid methyl ester (PCBM) are 3.50% and 1.21% for PSCs with and without the ZnO thin film, respectively. Light intensity dependence of the photocurrent and the capacitance-voltage measurement demonstrate that the increased PCEs are due to the restriction of the strong bimolecular recombination in the interface when a thin ZnO layer is inserted between the polymer active layer and the ITO electrode. These results demonstrate that the ZnO thin film plays an important role in the performance of PSCs with an inverted device structure.YANG TingBin QIN DongHuan LAN LinFeng HUANG WenBo GONG Xiong PENG JunBiao CAO Yong 2012Science China Chemistry2012,55,5:10
2Very-High Color Rendering Index Hybrid White Organic Light-Emitting Diodes with Double Emitting Nanolayers显示文摘A very-high color rendering index white organic light-emitting diode(WOLED) based on a simple structure was successfully fabricated. The optimized device exhibits a maximum total efficiency of 13.1 and 5.4 lm/W at 1,000 cd/m2. A peak color rendering index of 90 and a relatively stable color during a wide range of luminance were obtained. In addition, it was demonstrated that the 4,40,400-tri(9-carbazoyl) triphenylamine host influenced strongly the performance of this WOLED.These results may be beneficial to the design of both material and device architecture for high-performance WOLED.Baiquan Liu Miao Xu Lei Wang Hong Tao Yueju Su Dongyu Gao Linfeng Lan Jianhua Zou Junbiao Peng 2014Nano-Micro Letters2014,6,4:4
3Li4-xSbxSn1-xS4 solid solutions for air-stable solid electrolytes显示文摘The sulfide solid electrolytes have the characteristics of high ionic conductivity and low grain boundary resistance, which make them suitable for bulk-type all-solid-state batteries. However, most of them suffer from poor stability in air. Here, we explore the air stable sulfide solid electrolytes in Li4-xSbxSn1-xS4 system. The solid solutions of Li4-xSbxSn1-xS4(0 ≤ x ≤ 0.5) can be formed in Li4-xSbxSn1-xS4 system. Li3.8 Sb0.2 Sn0.8 S4 achieves the highest ionic conductivity of 3.5 × 10-4 S cm-1 in this system,which is 5 times as that of Li4 Sn S4 and 3 orders of magnitude higher than that of Li3 Sb S4, respectively. Li3.8 Sb0.2 Sn0.8 S4 crystallizes into the same structure with high ionic conductivity phase of β-Li3 PS4. Moreover, Li3.8 Sb0.2 Sn0.8 S4 owns good stability in humid air. Matching with LiCoO2 and Li4 Ti5 O12,Li3.8 Sb0.2 Sn0.8 S4 exhibits the potential to be applied in all-solid-state batteries.Zhuoran Zhang Jianxing Zhang Yulong Sun Huanhuan Jia Linfeng Peng Yunyang Zhang Jia Xie 2020Journal of Energy Chemistry2020,29,2:2
4Numerical study of mono-crystalline silicon solar cells with passivated emitter and rear contact configuration for the efficiency beyond 24% based on mass production technology显示文摘Mono-crystalline silicon solar cells with a passivated emitter rear contact(PERC)configuration have attracted extensive attention from both industry and scientific communities.A record efficiency of 24.06%on p-type silicon wafer and mass production efficiency around 22%have been demonstrated,mainly due to its superior rear side passivation.In this work,the PERC solar cells with a p-type silicon wafer were numerically studied in terms of the surface passivation,quality of silicon wafer and metal electrodes.A rational way to achieve a 24%mass-production efficiency was proposed.Free energy loss analyses were adopted to address the loss sources with respect to the limit efficiency of 29%,which provides a guideline for the design and manufacture of a high-efficiency PERC solar cell.Peng Wang Gaofei Li Miao Wang Hong Li Jing Zheng Liyou Yang Yigang Chen Dongdong Li Linfeng Lu 2020Journal of Semiconductors2020,41,6:2

7Facile synthesis of Li2S@C composites as cathode for Li–S batteries显示文摘Lithium sulfide (Li2S) provides a promising route for lithium storage due to high theoretical specific capacity (1166 mAh g-1). The electrochemical performance of Li2S can be significantly enhanced by forming Li2S-carbon composites with the introduction of carbon. However, the complex synthesis method of Li2S-carbon composites restrains the large-scale productivity. Herein, we propose a facile route to prepare carbon coated Li2S-carbon nanotube composites (Li2S@C-CNT) via spray drying and heat treatment, which is a low-cost and large-scale method for facile synthesis of Li2S-carbon composites. For the Li2S@C-CNT composites, Li2S nanoparticles are contacted with surrounding particles due to the 3D CNTs framework. The novel construction not only suppresses the diffusion of polysulfides during cycling, but also remarkably accelerates the transport of electron and ion, resulting in a high specific capacity (1100 mAh g^-1) and good cycling performance. The rational designed architecture and good electrochemical performance of Li2S@C-CNT will pave the avenue for realizing high energy density of Li2S-based batteries.Xin Chen Linfeng Peng Lixia Yuan Rui Zeng Jingwei Xiang Weilun Chen Kai Yuan Jie Chen Yunhui Huang Jia Xie 2019Journal of Energy Chemistry2019,28,10:1

9Aromatic inorganic acid radical显示文摘Stable radicals are challenging to prepare due to their intrinsic high reactivity.Herein,three trisphenolamine radicals were readily synthesized and exhibited unexpected thermal/electrochemical stability and semiconductor property.These three nitroxide radicals could be considered as a class of aromatized nitro groups or HNO3 derivatives.The closed-shell nitro-like and open-shell nitroxide resonance structure contribute to their outstanding stability.Furthermore,the tunable ground states,extremely low band gap and p-type charge transport properties were systematically investigated.More importantly,the work presents the concept of aromatic inorganic acid radical(AIAR)and aggregation-induced radical(AIR)mechanism to understand the intrinsic structureproperty relationship of these radicals.In addition,we provide a novel strategy for the design of stable and low bandgap radicals for organic electronics,magnetics,spintronics,etc.Jiawen Zhou Weiya Zhu Miao Zeng Qingqing Yang Ping Li Linfeng Lan Junbiao Peng Yuan Li Fei Huang Yong Cao 2019Science China Chemistry2019,62,12:1
10Enabling ultrafast lithium-ion conductivity of Li_(2)ZrCl_(6) by indium doping显示文摘Solid-state batteries with high energy density and safety are promising next-generation battery systems.However,lithium oxide and lithium sulfide electrolytes suffer low ionic conductivity and poor electrochemical stability,respectively.Lithium halide solid electrolyte shows high conductivity and good compatibility with the pristine high-voltage cathode but limited applications due to the high price of rare metal.Zr-based lithium halides with low cost and high stability possess great potential.Herein,a small amount of In^(3+)is introduced in Li_(2)ZrCl_(6) to synthesize Li_(2.25)Zr_(0.75)In_(0.25)Cl_(6) electrolytes with a high room temperature Li-ion conductivity of 1.08 mS/cm.Solid-state batteries using Li_(2.25)Zr_(0.75)In_(0.25)Cl_(6)/Li_(5.5)PS_(4.5)Cl_(1.5) bilayer solid electrolytes combined with Li-In anode and pristine LiNi_(0.7)Mn_(0.2)Co_(0.1)O_(2) cathode deliver high initial discharge capacities under different cut-off voltages.This work provides an effective strategy for enhancing the conductivity of Li2ZrCl6 electrolytes,promoting their applications in solid-state batteries.Shuai Chena Chuang Yu Shaoqing Chen Linfeng Peng Cong Liao Chaochao Wei Zhongkai Wu Shijie Cheng Jia Xie 2022Chinese Chemical Letters2022,33,10:1
11Percutaneous transhepatic intrahepatic portosystemic shunt for variceal bleeding: A series of six cases and literature review显示文摘Objectives:To present a case series of modified transjugular intrahepatic portosystemic shunts(TIPS) and percutaneous transhepatic intrahepatic portosystemic shunts(PTIPS) in cirrhotic patients with variceal bleeding(VB).In addition,the scientific literature pertaining to PTIPS was reviewed.Methods:This retrospective clinical case series included six cirrhotic patients with VB who were treated with PTIPS after the failure of endoscopic band ligation or endoscopic injection sclerotherapy combined with vasoactive drugs.The treatment was conducted between January 2017 and June 2019 at a single institution.Three patients suffered from severe atrophy of the right or left lobar of the liver as well as the main right or left branch of the portal vein.The remaining three patients showed severe atrophy of the whole liver and portal vein,resulting in widening of the liver fissure.A paired t-test was used to compare the changes in portal pressure gradient between before and after the PTIPS operation.The rebleeding rate,treatment efficacy,complications,and technical success rate were all assessed during follow-up.Results:All six PTIPS procedures were performed successfully,with no severe procedural-related complications observed.None of the patients experienced VB during a mean follow-up of 22.8(range,18.0-28.0) months.The mean portosystemic pressure gradient decreased from 28.3 ± 4.3 mmHg pre-procedure to 12.3 ± 2.6 mmHg immediately post-procedure(P <0.001).At follow-up,one patient was found to have developed grade 2 hepatic encephalopathy thrice during the first year,according to the West Haven criteria.However,this was resolved following medical treatment.Conclusions:When the patient’s portal venous anatomy is unconducive to the performance of TIPS using the transjugular approach,PTIPS can be considered as a safe,effective complementary surgical approach for patients with VB.Hang Du Binyan Zhong Peng Zhang Wansheng Wang Jian Shen Shuai Zhang Wanci Li Haohuan Tang Linfeng Zhou Weihao Yang Xiaoli Zhu 2021Journal of Interventional Medicine2021,4,1:1
12Na3.8[Sn0.67Si0.33]0.8Sb0.2S4:A quinary sodium fast ionic conductor for all-solid-state sodium battery显示文摘Strategy of Sb-substitution is carried out on the template structure Na4Sn0.67M0.33S4(M=Si,Ge),which affords a series of quinary sulfide-based sodium fast ionic conductors formulated as Na4-x[Sn0.67M0.33]1-xSbxS4(M=Si,x=0.1,0.2,0.3;M=Ge,x=0.2.).Among them,the highest ambient ionic conductivity(1.75×10^-4 S cm^-1)is achieved when M=Si and x=0.2.The new fast ionic conductor Na3.8[Sn0.67Si0.33]0.8Sb0.2S4 is isostructural to its structure template Na4Sn0.67Si0.33S4 and thus crystallizes in the space group of I41/acd.It is shown that the incorporation of Sb improves the ionic conductivity.The study of lattice parameters shows that the improvement of the ion conductivity by Sbsubstitution is mainly due to the enlarged crystal lattice.Furthermore,using Na3.8[Sn0.67Si0.33]0.8Sb0.2S4as solid electrolytes,room temperature all-solid-state sodium battery of Se0.05S0.95@pPAN/Na3Sn is realized,which proves the novel fast ionic conductor a potential candidate to apply in sodium solid state battery.This work not only extends the scope of Na4[Sn0.67Si0.33]S4,the I41/acd space group template,but also deepens the understanding of the lattice size effect on the structure and property relationship by aliovalent substitution.Huanhuan Jia Linfeng Peng Zhuoran Zhang Tao An Jia Xie 2020Journal of Energy Chemistry2020,29,9:1

18Cryo-EM structure of L-fucokinase/GDP-fucose pyrophosphorylase(FKP)in Bacteroides fragilis显示文摘Dear Editor,L-Fucose(6-deoxy-L-galactose,fucose)is the basic compone nt of a variety of glyca n structures.The fucosylated oligosaccharides participate in a variety of cellular activities,like the cell-cell recognition,selectin-mediated leukocyteendothelial adhesion and the formation of Lewis blood group antigens(Ma et al.,2006).GDP-fucose is an important fucose donor in the process of fucosylated oligosaccharides formation.Two pathways of GDP-fucose synthesis are present in the cytosol of mammalian cells,including the de novo pathway and the salvage pathway(Becker et al.,2003).In the salvage pathway,cells use fucose from the extracellular or lysosomal sources to synthesize GDP-fucose.Ying Liu Huifang Hu Jia Wang Qiang Zhou Peng Wu Nieng Yan Hong-Wei Wang Jia-Wei Wu Linfeng Sun 2019Protein & Cell2019,10,5:0
19Tuning Solid Interfaces via Varying Electrolyte Distributions Enables High-Performance Solid-State Batteries显示文摘Solid/solid interface is the major challenge for high-performance solid-state batteries.Solid electrolytes(SEs)play a crucial role in the fabrication of effective interfaces in solid-state batteries.Herein,the electrolyte distribution with varied particle sizes is tuned to construct solid-state batteries with excellent performance at different operating temperatures.Solid-state batteries with the configuration S/L(small-sized SE in composite cathode and large-sized SE in electrolyte layer)show the best performance at room temperature(168 mA h g^(−1) at 0.2 C,retention of 99%,100 cycles)and−20°C(89 mA h g^(−1) at 0.05 C),while the configuration S/S displays better performance at elevated temperature.The superior performance of S/L battery is associated with faster lithium-ion dynamics due to the better solid/solid interface between active materials and electrolytes.Moreover,the inferior performance at 60℃is caused by the formation of voids and cracks in the electrolyte layer during cycling.In contrast,the S/S battery delivers superior performance at elevated operating temperature because of the integrated structure.This work confirms that tailoring electrolyte size has significant effect on fabricating all-climate solid-state batteries.Linfeng Peng Chuang Yu Ziqi Zhang Ruonan Xu Mengjun Sun Long Zhang Shijie Cheng Jia Xie 2023Energy & Environmental Materials2023,6,2:0
