1Progress of the key materials for organic solar cells显示文摘Organic solar cells have attracted academic and industrial interests due to the advantages like lightweight,flexibility and roll-to-roll fabrication.Nowadays,18%power conversion efficiency has been achieved in the state-of-the-art organic solar cells.The recent rapid progress in organic solar cells relies on the continuously emerging new materials and device fabrication technologies,and the deep understanding on film morphology,molecular packing and device physics.Donor and acceptor materials are the key materials for organic solar cells since they determine the device performance.The past 25 years have witnessed an odyssey in developing high-performance donors and acceptors.In this review,we focus on those star materials and milestone work,and introduce the molecular structure evolution of key materials.These key materials include homopolymer donors,D-A copolymer donors,A-D-A small molecular donors,fullerene acceptors and nonfullerene acceptors.At last,we outlook the challenges and very important directions in key materials development.Yang Tong Zuo Xiao Xiaoyan Du Chuantian Zuo Yuelong Li Menglan Lv Yongbo Yuan Chenyi Yi Feng Hao Yong Hua Ting Lei Qianqian Lin Kuan Sun Dewei Zhao Chunhui Duan Xiangfeng Shao Wei Li Hin-Lap Yip Zhengguo Xiaol Bin Zhang Qingzhen Bian Yuanhang Cheng Shengjian Liu Ming Cheng Zhiwen Jin Shangfeng Yang Liming Ding 2020Science China Chemistry2020,63,6:15
2Removal of formaldehyde over Mn_xCe_(1- x)O_2 catalysts: Thermal catalytic oxidation versus ozone catalytic oxidation显示文摘MnxCe1-xO2(x:0.3–0.9)prepared by Pechini method was used as a catalyst for the thermal catalytic oxidation of formaldehyde(HCHO).At x=0.3 and 0.5,most of the manganese was incorporated in the fluorite structure of Ce O2to form a solid solution.The catalytic activity was best at x=0.5,at which the temperature of 100%removal rate is the lowest(270°C).The temperature for 100%removal of HCHO oxidation is reduced by approximately 40°C by loading 5 wt.%Cu Oxinto Mn0.5Ce0.5O2.With ozone catalytic oxidation,HCHO(61 ppm)in gas stream was completely oxidized by adding 506 ppm O3over Mn0.5Ce0.5O2catalyst with a GHSV(gas hourly space velocity)of 10,000 hr-1at 25°C.The effect of the molar ratio of O3to HCHO was also investigated.As O3/HCHO ratio was increased from 3 to 8,the removal efficiency of HCHO was increased from 83.3%to 100%.With O3/HCHO ratio of 8,the mineralization efficiency of HCHO to CO2was 86.1%.At 25°C,the p-type oxide semiconductor(Mn0.5Ce0.5O2)exhibited an excellent ozone decomposition efficiency of 99.2%,which significantly exceeded that of n-type oxide semiconductors such as Ti O2,which had a low ozone decomposition efficiency(9.81%).At a GHSV of 10,000 hr-1,[O3]/[HCHO]=3 and temperature of 25°C,a high HCHO removal efficiency(≥81.2%)was maintained throughout the durability test of 80 hr,indicating the long-term stability of the catalyst for HCHO removal.Jia Wei Li Kuan Lun Pan Sheng Jen Yu Shaw Yi Yan Moo Been Chang 2014Journal of Environmental Sciences2014,26,12:9
3Paired related homeobox 1 transactivates dopamine D2 receptor to maintain propagation and tumorigenicity of glioma-initiating cells显示文摘Glioblastoma multiforme (GBM ) 是有有限治疗学的工具和差的预后的一个高度侵略的大脑肿瘤。最近的研究显示开始 glioma cells/glioma 干细胞(GICs/GSCs ) 可能为肿瘤开始,渗入,和复发负责。GIC 能异常地采用平衡胚胎的神经先锋的自强和区别的分子的机械。这里,我们发现那配对的相关 homeobox 1 (PRRX1 ) ,以前是的一个 homeodomain 抄写因素报导了控制骨胳的开发,在外皮的神经祖先被表示并且为他们的自强和合适的区别被要求。进一步, PRRX1 是在 glioma 样品和标签 GIC 的 overrepresented。Glioma 房间和 GIC 与 PRRX1 弄空不能在 vitro 宣传或在异种皮移植老鼠模型形成肿瘤。PRRX1 调整的 GIC 自强功能被多巴胺 D2 受体(DRD2 ) 调停。PRRX1 直接在 GIC 把它的表示绑在 DRD2 倡导者和 transactivates。发信号的 DRD2 的阻塞妨碍 GIC 自强,而它的 overexpression 恢复宣传和弄空 PRRX1 的 GIC 的 tumorigenic 潜力。最后, PRRX1 加强经由调停 DRD2 的细胞外的信号相关的 kinase (英皇家空军之阶级最低之兵) 和 AKT 的 GIC 激活。因此,我们的学习建议那治疗学的指向在 GIC 的 PRRX1DRD2ERK/AKT 轴是为对待 GBM 的有希望的策略。Yamu Li Wen Wang Fangyu Wang Qiushuang Wu Wei Li Xiaoling Zhong Kuan Tian Tao Zeng Liang Gao Ying Liu Shu Li Xiaobing Jiang Guangwei Du Yan Zhou 2017Journal of Molecular Cell Biology2017,9,4:5
4The strategies of advanced cathode composites for lithium-sulfur batteries显示文摘Lithium-sulfur batteries have been widely nominated as one of the most promising next-generation electrochemical storage systems due to its low cost, high capacity and energy density. However, its practical application is still hindered by poor cycling lifetime, low Coulombic efficiency, instability and small scales. In the last decade, the electrochemical performances of the lithium-sulfur batteries have been improved by developing various novel nanoarchitectures as qualified hosts, and enhancing the sulfur loading with effective encapsulating strategies. The review summarizes the major sulfur cooperating strategies of cathodes based on background and latest progress of the lithium-sulfur batteries. The novel cooperating strategies of physical techniques and chemical synthesis techniques are discussed in detail. Based on the rich chemistry of sulfur, we paid more attention to the highlights of sulfur encapsulating strategies. Furthermore, the critical research directions in the coming future are proposed in the conclusion and outlook section.ZHOU Kuan FAN XiaoJing WEI XiangFeng LIU JieHua 2017Science China(Technological Sciences)2017,60,2:5
5Anatomical variation of infra-pyloric artery origination: A prospective multicenter observational study (IPA-Origin)显示文摘Objective: Infra-pyloric artery(IPA) is an important anatomical landmark in treatment of gastric cancer and is the key vessel for pylorus-preserving gastrectomy and subgroup of infra-pyloric lymph nodes. However, its anatomical variation is not thoroughly understood. Our study aimed to clarify the origination of the IPA.Methods: We did this prospective, multicenter, open-label, observational study at gastric surgery departments of34 hospitals in China. Gastric cancer patients aged 18 years or older and scheduled to undergo elective total or distal gastrectomy were assigned. During the surgery, IPA dissecting and exposing the origination point with photographs or video clips were required. The primary outcome was the origination of the IPA. Analysis of variance, χ~2 tests and Fisher's tests were used to analyze the differences between groups. The study is registered at Clinicaltrials.gov(No. NCT03071237).Results: Between May 8 and July 31, 2017, 429 patients were assigned for the study, and 419(97.7%) patients had the IPA dissected and recorded through photograph or video and were included in the primary outcome analysis. The median age was 62 years old, and 73.7% were male. Among the patients, 78.5% received laparoscopic surgery. Single IPA origination was identified in 398(95.0%) patients, including gastroduodenal artery(GDA) in154(36.8%) patients, anterior superior pancreaticoduodenal artery(ASPDA) in 130(31.0%) patients, and right gastroepiploic artery(RGEA) in 114(27.2%) patients. Fifteen(3.6%) patients were identified with multiple IPA and 6(1.4%) patients were identified as IPA absence. The differences in the distribution of surgical approach(P=0.003) and geographic area(P=0.030) were statistically significant. No difference was shown in sex, age,gastrectomy type, tumor location, and clinical T, N and M stage.Conclusions: Our study found that the IPA originates from GDA, ASPDA and RGEA in similar proportions.Laparoscopic surgery may be more helpful in dissection of the IPA than open surgery.Rulin Miao Jianjun Qu Zhengrong Li Daguang Wang Jiang Yu Weidong Zang Yong Li Fenglin Liu Jian Zhang Wu Song Kai Ye Su Yan Wei Wang Shuangyi Ren Lu Zang Changqing Jing Li Zhang Kuan Wang Weihua Fu Lin Fan Bin Liang Gang Zhao Jun Cai Li Yang Jiaming Zhu Jun You Kun Yang Qingxing Huang Zhaojian Niu Ning Ning Xingfeng Qiu Gang Ji Feng Liang Hua Huang Chao Gao Fei Shan Shuangxi Li Yongning Jia Lianhai Zhang Xiangji Ying Yan Zhang Zhaode Bu Xiangqian Su Gang Zhao Ziyu Li Jiafu Ji 2018Chinese Journal of Cancer Research2018,30,5:5
6m6A promotes R-loop formation to facilitate transcription termination显示文摘R-loops are three-stranded nucleic acid structures consisting of a DNA:RNA heteroduplex and a displaced single DNA strand.They constitute a prevalent genomic feature with important functions in all kingdoms of eukaryotes.1,2,3 For example,R-loops have been found over unmethylated CpG island promoters,G-rich terminators,and many other regulatory chromosomal loci.2,3 Moreover,they are essential for diverse cellular processes,such as immunoglobulin class switching,mitotic chromosome segregation,4 DNA replication and repair,genome stability regulation,5 as well as in multiple steps during transcription.6,7 R-loops can be formed both in cis and in trans;cis R-loops are formed between a nascent RNA and its DNA template following transcribing RNA polymerases and exert co-transcriptional regulatory effects.3,8 Therefore,it is important to control their formation and resolution,and many external factors have already been identified for this process.7 However,it is still unknown whether the intrinsic properties of the RNA itself,such as various modifications,can modulate the formation of DNA:RNA hybrids.Xin Yang Qian-Lan Liu Wei Xu Yi-Chang Zhang Ying Yang Lin-Fang Ju Jing Chen Yu-Sheng Chen Kuan Li Jie Ren Qianwen Sun Yun-Gui Yang 2019Cell Research2019,29,12:5
7Nonlinear Parametric Vibration of a Fluid-Conveying Pipe Flexibly Restrained at the Ends显示文摘In this paper,the nonlinear parametric vibration of fluid-conveying pipes flexibly restrained at both ends and subjected to the pulsation flow excitation is investigated.The nonlinear equation of motion is derived using Hamilton^principle by considering the Kevin-Voigt viscoelastic damping,the geometric nonlinearity and the translational and rotational springs supported at the ends.The mode functions and eigen-frequencies are determined by the assumed mode method according to the elastic boundary conditions.The Galerkin method is implemented to obtain the natural frequencies and mode shapes of the pipe conveying fluid with different flow velocities.The effects of flexibly restrained conditions on stability of the pipe are analyzed.The nonlinear responses of the pipe under pulsating flow excitation are solved by the direct numerical method.The vibration behaviors are discussed in details,such as time history,frequency spectrum,phase-plane portrait,Poincare map and motion trajectory.The results show that the responses of sub-harmonic resonance and combination resonance can also be reflected in the rigidly supported pipes.The 1/5,1/8 and 1/13 sub-harmonic resonances can occur at certain excitation frequencies of the nonlinear parametric vibration system.The steady-state response amplitudes increase by a large margin and significantly affect the stability of the pipe.The effects of different spring stiffness coefficients on the parametric resonance responses are presented.For larger translational springs and rotational stiffness coefficients,the resonance frequencies shift to higher regions and the resonance amplitudes may reduce by a certain extent in accordance with the rigid-body motion.This study can provide helpful guidance on the analysis and design of piping systems subject to vibrations.Qian Li Wei Liu Kuan Lu Zhufeng Yue 2020Acta Mechanica Solida Sinica2020,33,3:4
8Turbulent characteristics and rotation correction of wall function in rotating channel with high local rotation parameter显示文摘The turbulent fluctuation and the rotation correction of wall function law are investigated in the entrance section of a rotating channel. The one-dimensional hot wire probe and the X-type probe are utilized to measure the boundary layer at four streamwise stations. Through the analysis on the boundary layer near the leading side and trailing side, it is found that the turbulent fluctuation is promoted in the trailing side whereas suppressed in the leading side. This difference is attributed to the Coriolis instability near the trailing side. In addition, considering the local rotation parameter Rc, whose maximum absolute value is 0.014, is larger than that in previous research, whose maximum value is 0.007, the whole process of the relaminarization is captured. To understand this phenomenon better, the effects of the generation term and the Coriolis term in the transport equation of the Reynolds stress are discussed. In addition, the rotation correction of the viscous-Coriolis region and the Coriolis region are discussed, a new revising method for the wall function is proposed.Zhi TAO Huijie WU Ruquan YOU Haiwang LI Kuan WEI 2018Chinese Journal of Aeronautics2018,31,10:4

11CsPb(I_(x)Br_(1-x))_(3) solar cells显示文摘Owing to its nice performance, low cost, and simple solution-processing, organic-inorganic hybrid perovskite solar cell(PSC) becomes a promising candidate for next-generation high-efficiency solar cells.The power conversion efficiency(PCE) has boosted from 3.8% to 25.2% over the past ten years. Despite the rapid progress in PCE, the device stability is a key issue that impedes the commercialization of PSCs. Recently, all-inorganic cesium lead halide perovskites have attracted much attention due to their better stability compared with their organic-inorganic counterpart. In this progress report, we summarize the properties of CsPb(IxBr1-x)3 and their applications in solar cells. The current challenges and corresponding solutions are discussed. Finally, we share our perspectives on CsPb(IxBr1-x)3 solar cells and outline possible directions to further improve the device performance.Xue Jia Chuantian Zuo Shuxia Tao Kuan Sun Yixin Zhao Shangfeng Yang Ming Cheng Mingkui Wang Yongbo Yuan Junliang Yang Feng Gao Guichuan Xing Zhanhua Wei Lijun Zhang Hin-Lap Yip Mingzhen Liu Qing Shen Longwei Yin Liyuan Han Shengzhong Liu Lianzhou Wang Jingshan Luo Hairen Tan Zhiwen Jin Liming Ding 2019Science Bulletin2019,64,20:2

14Long non-coding RNA LncKdm2b regulates cortical neuronal differentiation by cis-activating Kdm2b显示文摘The mechanisms underlying spatial and temporal control of cortical neurogenesis of the brain are largely elusive.Long non-coding RNAs(lncRNAs)have emerged as essential cell fate regulators.Here we found LncKdm2b(also known as Kancr),a lncRNA divergently transcribed from a bidirectional promoter of Kdm2b,is transiently expressed during early differentiation of cortical projection neurons.Interestingly,Kdm2b’s transcription is positively regulated in cis by LncKdm2b,which has intrinsic-activating function and facilitates a permissive chromatin environment at the Kdm2b’s promoter by associating with hnRNPAB.Lineage tracing experiments and phenotypic analyses indicated LncKdm2b and Kdm2b are crucial in proper differentiation and migration of cortical projection neurons.These observations unveiled a lncRNA-dependent machinery in regulating cortical neuronal differentiation.Wei Li Wenchen Shen Bo Zhang Kuan Tian Yamu Li Lili Mu Zhiyuan Luo Xiaoling Zhong Xudong Wu Ying Liu Yan Zhou 2020Protein & Cell2020,11,3:2
15Ballistic impact properties of woven bamboo-woven E-glass-unsaturated polyester hybrid composites显示文摘In this study, a laminated woven bamboo/woven E glass/unsaturated polyester composite is developed to combat a ballistic impact from bullet under shooting test. The aim of this study is to understand the fundamental effects of the woven bamboo arrangement towards increasing ballistic resistance properties. The work focusses on the ballistic limit test known as NIJ V50, which qualifies materials to be registered for use in combat armor panels. The results show that the composites withstood 482.5 m/s ± 5 limit of bullet velocity, satisfying the NIJ test at level II. The findings give a strong sound basis decision to engineers whether or not green composites are qualified to replace synthetic composites in certain engineering applications.Aidy Ali Rabiatun Adawiyah Kannan Rassiah Wei Kuan Ng Faiz Arifin Faiz Othman Muhammad Shauqi Hazin M.K.
