| 1 | A carbon-oxygen-bridged ladder-type building block for efficient donor and acceptor materials used in organic solar cells显示文摘A carbon-oxygen-bridged ladder-type donor unit(CO5) was invented and prepared via an ‘‘intramolecular demethanolization cyclization' approach. Its single crystal structure indicates enhanced planarity compared with the carbon-bridged analogue indacenodithiophene(IDT). Owing to the stronger electron-donating capability of CO5 than IDT, CO5-based donor and acceptor materials show narrower bandgaps. A donor-acceptor(D-A) copolymer donor(PCO5TPD) and an A-D-A nonfullerene acceptor(CO5IC) demonstrated higher performance than IDT-based counterparts, PIDTTPD and IDTIC, respectively. The better performance of CO5-based materials results from their stronger light-harvesting capability and higher charge-carrier mobilities. | Zuo Xiao Fan Liu Xinjian Geng Jianqi Zhang Shizhe Wang Yujun Xie Zhen Li Huai Yang Yongbo Yuan Liming Ding | 2017 | Science Bulletin2017，62，19： | 16 |
| 2 | Cu_2ZnSnS_4 thin films prepared by sulfurization of ion beam sputtered precursor and their electrical and optical properties显示文摘Cu2ZnSnS4 (CZTS) thin films were successfully prepared by sulfurization of ion bean sputtered precursors on soda-lime glass substrate. The single phase of stannite-type structure CZTS films were obtained as revealed in EDS and XRD analysis when the ratios of the constituents of CZTS thin films are close to stoichiometric by optimizing the conditions of precursor preparation and sulfurization. A low sheet resistivity as about 0.156 Ω·cm and a high absorption coefficient as 1×104 cm-1 were achieved in this method by Hall effect measurements and UV-VIS spectrophotometer. The optical band-gap energy of the CZTS sample is about 1.51 eV, which is very close to the optimum value for a solar-cell absorber. | ZHANG Jun SHAO Lexi FU Yujun XIE Erqing | 2006 | Rare Metals2006，25，z1： | 11 |
| 3 | Characteristics of volatile compounds removal in biogas slurry of pig manure by ozone oxidation and organic solvents extraction显示文摘Biogas slurry is not suitable for liquid fertilizer due to its high amounts of volatile materials being of complicated composition and peculiar smell. In order to remove volatiles from biogas slurry efficiently, the dynamic headspace and gas chromatography-mass spectrometry were used to clear the composition of volatiles. Nitrogen stripping and superfluous ozone were also used to remove volatiles from biogas slurry. The results showed that there were 21 kinds of volatile compounds in the biogas slurry, including sulfur compounds, organic amines, benzene, halogen generation of hydrocarbons and alkanes, some of which had strong peculiar smell. The volatile compounds in biogas slurry can be removed with the rate of 53.0% by nitrogen stripping and with rate of 81.7% by the oxidization and stripping of the superfluous ozone. On this basis, the removal rate of the volatile compounds reached 99.2% by chloroform and n-hexane extraction, and almost all of odor was eliminated. The contents of some dissolved organic compounds decreased obviously and however main plant nutrients had no significant change in the biogas slurry after being treated. | Yujun Wang Lianshuang Feng Xiaosong Zhao Xiulan Ma Jingmin Yang Huiqing Liu Sen Dou Miping Zhou Zhonglei Xie | 2013 | Journal of Environmental Sciences2013，25，9： | 7 |

In this work, six perylene bisimide-based red emitters, N,N''-bis(2-decyltetradecyl)-1-([1,1':3',1''-terphenyl]-5'-yl)perylene-3,4,9,10-diimide(STPH),N,N'-bis(2-decyltetradecyl)-1,7-bis([1,1':3',1''-terphenyl]-5'-yl)perylene-3,4,9,10-diimide(DTPH), N,N''-bis(2-decyltetradecyl)-1-(5'-phenyl-[1,1':3',1''-terphenyl]-4-yl)perylene-3,4,9,10-diimide(STRPH), N,N0-bis(2-decyltetradecyl)-1,7-bis(5'-phenyl-[1,1':3',1''-terphenyl]-4-yl)perylene-3,4,9,10-diimide(DTRPH),N,N0-bis(2-decyltetradecyl)-1-(4-(2,2-diphenylvinyl)phenyl)perylene-3,4,9,10-diimide(STTPE) and N,N'-bis(2-decyltetradecyl)-1,7-bis(4-(2,2-diphenylvinyl)phenyl)perylene-3,4,9,10-diimide(DTTPE), with the excellent chemical, thermal and photo-chemical stability, are synthesized through the convenient Suzuki coupling reaction, in which, the fluorescent properties can be modified easily from ACQ to AIE by just simply changing the bulky volume of the introduced aromatic substituents. After being fabricated into organic light-emitting diodes, STRPH exhibits the best performance with the maximum luminescence, power efficiency, current efficiency and external quantum efficiency of 1,948 cd m^(-2), 2.04 lm W^(-1), 5.85 cd A^(-1), 4.93% at Commission Internationale de L'Eclairage(CIE) coordinates of(0.56, 0.34),as the result of the high efficient energy transfer and good energy match achieved in the device. | Luyi Zong Yanbin Gong Yun Yu Yujun Xie Guohua Xie Qian Peng Qianqian Li Zhen Li | 2018 | Science Bulletin2018，63，2： | 2 |

| 10 | Molecular dynamics simulation of the deposition process of hydrogenated diamond-like carbon (DLC) films显示文摘The deposition process of hydrogenated diamond-like carbon (DLC) film greatly affects its frictional properties. In this study, CH3 radicals are selected as source species to deposit hydrogenated DLC films for molecular dynamics simulation. The growth and structural properties of hydrogenated DLC films are investigated and elucidated in detail. By comparison and statistical analysis, the authors find that the ratio of carbon to hydrogen in the films generally shows a monotonously increasing trend with the increase of impact energy. Carbon atoms are more reactive during deposition and more liable to bond with substrate atoms than hydrogen atoms. In addition, there exists a peak value of the number of hydrogen atoms deposited in hydrogenated DLC films. The trends of the variation are opposite on the two sides of this peak point, and it becomes stable when impact energy is greater than 80 eV. The average relative density also indicates a rising trend along with the increment of impact energy, while it does not reach the saturation value until impact energy comes to 50 eV. The hydrogen content in source species is a key factor to determine the hydrogen content in hydrogenated DLC films. When the hydrogen content in source species is high, the hydrogen content in hydrogenated DLC films is accordingly high. | ZHANG Yujun DONG GuangNeng MAO JunHong XIE YouBai | 2008 | Chinese Science Bulletin2008，53，7： | 2 |
| 11 | Formative pluripotent stem cells show features of epiblast cells poised for gastrulation显示文摘The pluripotency of mammalian early and late epiblast could be recapitulated by naïve embryonic stem cells(ESCs)and primed epiblast stem cells(EpiSCs),respectively.However,these two states of pluripotency may not be sufficient to reflect the full complexity and developmental potency of the epiblast during mammalian early development.Here we report the establishment of self-renewing formative pluripotent stem cells(fPSCs)which manifest features of epiblast cells poised for gastrulation.fPSCs can be established from different mouse ESCs,pre-/early-gastrula epiblasts and induced PSCs.Similar to pre-/early-gastrula epiblasts,fPSCs show the transcriptomic features of formative pluripotency,which are distinct from naïve ESCs and primed EpiSCs.fPSCs show the unique epigenetic states of E6.5 epiblast,including the super-bivalency of a large set of developmental genes.Just like epiblast cells immediately before gastrulation,fPSCs can efficiently differentiate into three germ layers and primordial germ cells(PGCs)in vitro.Thus,fPSCs highlight the feasibility of using PSCs to explore the development of mammalian epiblast. | Xiaoxiao Wang Yunlong Xiang Yang Yu Ran Wang Yu Zhang Qianhua Xu Hao Sun Zhen-Ao Zhao Xiangxiang Jiang Xiaoqing Wang Xukun Lu Dandan Qin Yujun Quan Jiaqi Zhang Ng Shyh-Chang Hongmei Wang Naihe Jing Wei Xie Lei Li | 2021 | Cell Research2021，31，5： | 2 |
| 12 | Blue AIEgens bearing triphenylethylene peripheral:adjustable intramolecular conjugation and good device performance显示文摘The new approaches to construct deep blue aggregation-induced emission(AIE) materials have been explored, which control the conjugation by two different strategies, to make a great step for the commercialization of organic light-emitting diodes. In order to shorten the intramolecular conjugation length, triphenylethylene(t PE)was utilized to construct blue AIEgens as peripheral groups,instead of tetraphenylethylene(TPE), the famous AIE star molecule, to yield three blue AIEgens of 3,4-Bt PE-PI, 4,4-Bt PE-PI and 4,4-Bt PE-PPI. Nondoped electroluminescence devices are fabricated by using these three AIEgens as the emitting material layer, the best performance of 3.8 cd/A as the maximum current efficiency achieved at the commission internationale de l'Eclairage coordinates of(0.17, 0.18). | Can Wang Le Li Xuejun Zhan Zhijun Ruan Yujun Xie Quanyuan Hu Shanghui Ye Qianqian Li Zhen Li | 2016 | Science Bulletin2016，61，22： | 2 |
