| 1 | Advanced hydrogels for the repair of cartilage defects and regeneration显示文摘Cartilage defects are one of the most common symptoms of osteoarthritis(OA),a degenerative disease that affects millions of people world-wide and places a significant socio-economic burden on society.Hydrogels,which are a class of biomaterials that are elastic,and display smooth surfaces while exhibiting high water content,are promising candidates for cartilage regeneration.In recent years,various kinds of hydrogels have been developed and applied for the repair of cartilage defects in vitro or in vivo,some of which are hopeful to enter clinical trials.In this review,recent research findings and developments of hydrogels for cartilage defects repair are summarized.We discuss the principle of cartilage regeneration,and outline the requirements that have to be fulfilled for the deployment of hydrogels for medical applications.We also highlight the development of advanced hydrogels with tailored properties for different kinds of cartilage defects to meet the requirements of cartilage tissue engineering and precision medicine. | Wei Wei Yuanzhu Ma Xudong Yao Wenyan Zhou Xiaozhao Wang Chenglin Li Junxin Lin Qiulin He Sebastian Leptihn Hongwei Ouyang | 2021 | Bioactive Materials2021，6，4： | 8 |

| 3 | Monte-Carlo simulation of pinhole collimator of a small field of view gamma camera for small animal imaging显示文摘Needs in scintimammography applications,especially for small animal cardiac imaging,lead to develop a small field of view,high spatial resolution gamma camera with a pinhole collimator.However the ideal pinhole collimator must keep a compromise between spatial resolution and sensitivity.In order to design a pinhole collimator with an optimized sensitivity and spatial resolution,the spatial resolution and the geometric sensitivity response as a function of the source to collimator distance has been obtained by means of Monte-Carlo simulation for a small field of view gamma camera with a pinhole collimator of various-hole diameters.The results show that the camera with pinhole of 1 mm,1.5 mm and 2 mm diameter has respectively spatial resolution of 1.5 mm,2.25 mm and 3 mm and geometric sensitivity of 0.016%,0.022%and 0.036%,while the source to collimator distance is 3 cm.We chose the pinhole collimator with hole diameter size of 1.2 mm for our the gamma camera designed based on the trade-off between sensitivity and resolution. | ZHU Jie MA Wenyan ZHU Yufeng MA Hongguang WU Yuelei HU Huasi ZHANG Boping HUO Yonggang LIU Silu JIAN Bin WANG Zhaomin | 2009 | Nuclear Science and Techniques2009，20，1： | 4 |
| 4 | High-performance all-polymer solar cells enabled by a novel low bandgap non-fully conjugated polymer acceptor显示文摘The non-fully conjugated polymer as a new class of acceptor materials has shown some advantages over its small molecular counterpart when used in photoactive layers for all-polymer solar cells(all-PSCs),despite a low power conversion efficiency(PCE)caused by its narrow absorption spectra.Herein,a novel non-fully conjugated polymer acceptor PFY-2TS with a low bandgap of~1.40 eV was developed,via polymerizing a largeπ-fused small molecule acceptor(SMA)building block(namely YBO)with a non-conjugated thioalkyl linkage.Compared with its precursor YBO,PFY-2TS retains a similar low bandgap but a higher LUMO level.Moreover,compared with the structural analog of YBO-based fully conjugated polymer acceptor PFY-DTC,PFY-2TS shows a similar absorption spectrum and electron mobility,but significantly different molecular crystallinity and aggregation properties,which results in optimal blend morphology with a polymer donor PBDB-T and physical processes of the device in all-PSCs.As a result,PFY-2TS-based all-PSCs achieved a PCE of 12.31%with a small energy loss of 0.56 eV enabled by the reduced non-radiative energy loss(0.24 eV),which is better than that of 11.08%for the PFY-DTC-based ones.Our work clearly demonstrated that non-fully conjugated polymers as a new class of acceptor materials are very promising for the development of high-performance all-PSCs. | Qunping Fan Ruijie Ma Tao Liu Jianwei Yu Yiqun Xiao Wenyan Su Guilong Cai Yuxiang Li Wenhong Peng Tao Guo Zhenghui Luo Huiliang Sun Lintao Hou Weiguo Zhu Xinhui Lu Feng Gao Ellen Moons Donghong Yu He Yan Ergang Wang | 2021 | Science China Chemistry2021，64，8： | 3 |

| 6 | A redox-active conjugated microporous polymer cathode for highperformance lithium/potassium-organic batteries显示文摘Organic redox-active materials have emerged as a class of electrode materials for rechargeable batteries due to their high redox activity,low cost,structure diversity and flexibility.However,the high solubility of organic small molecules in organic electrolytes commonly leads to the fast capacity decay with cycling.Herein,we report a redox-active conjugated microporous polymer of poly(pyrene-co-anthraquinone)(Py Aq)cathode material consisting of pyrene and anthraquinone units.Benefiting from the highly cross-linked polymer structure with insoluble nature in organic electrolytes,the high surface area and the plentiful redox-active carbonyl groups,the Py Aq cathode demonstrates outstanding electrochemical performances for both lithium-ion batteries(LIBs)and potassium-ion batteries(KIBs).Specifically,the Py Aq cathode for LIBs delivers a high reversible capacity of 169 m Ah g^-1 at the current density of 20 m A g^-1,a high rate capability(142 m Ah g^-1 at 1000 m A g^-1)and an excellent cycling stability for 4000 cycles.Additionally,the Py Aq cathode for KIBs also exhibits a high reversible capacity of143 m Ah g^-1 with a long cycling life over 800 cycles.The excellent electrochemical performance demonstrates that the newly developed Py Aq could be an attractive cathode material for the advanced energy storage technologies. | Lian-Wei Luo Chong Zhang Peixun Xiong Yongbo Zhao Wenyan Ma Yu Chen Jing Hui Zeng Yunhua Xu Jia-Xing Jiang | 2021 | Science China Chemistry2021，64，1： | 3 |
| 7 | The source and transport of bioaerosols in the air:A review显示文摘Recent pandemic outbreak of the corona-virus disease 2019(COVID-19)has raised widespread concerns about the importance of the bioaerosols.They are atmospheric aerosol particles of biological origins,mainly including bacteria,fungi,viruses,pollen,and cell debris.Bioaerosols can exert a substantial impact on ecosystems,climate change,air quality,and public health.Here,we review several relevant topics on bioaerosols,including sampling and detection techniques,characterization,effects on health and air quality,and control methods.However,very few studies have focused on the source apportionment and transport of bioaerosols.The knowledge of the sources and transport pathways of bioaerosols is essential for a comprehensive understanding of the role microorganisms play in the atmosphere and control the spread of epidemic diseases associated with them.Therefore,this review comprehensively summarizes the up to date progress on the source characteristics,source identification,and diffusion and transport process of bioaerosols.We intercompare three types of diffusion and transport models,with a special emphasis on a widely used mathematical model.This review also highlights the main factors affecting the source emission and transport process,such as biogeographic regions,land-use types,and environmental factors.Finally,this review outlines future perspectives on bioaerosols. | Wenwen Xie Yanpeng Li Wenyan Bai Junli Hou Tianfeng Ma Xuelin Zeng Liyuan Zhang Taicheng An | 2021 | Frontiers of Environmental Science & Engineering2021，15，3： | 2 |
| 8 | Development of a compact high resolution gamma-ray detector for E-CT applications显示文摘A compact gamma-ray detector with good spatial resolution for emission computed tomography (E-CT) applications has been developed. The detector is composed of NaI(Tl) scintillation pixels array and Hamamastu R2486-05 PSPMT. Having a pixel size of 2 mm × 2 mm and an overall dimension of 48.2 mm × 48.2mm × 5 mm, it has 484 pixels in a 22×22 matrix. An average spatial resolution of 2.5mm (FWHM) was achieved. The slope of position linearity is constant within 10% in a range of 40mm. After corrections, the average value of differential non-linearity and absolute non-linearity were 0.16mm and 0.535mm respectively, and a 17% at FWHM of total energy resolution for 241Am was obtained. | ZHU Jie MA Hongguang MA Wenyan ZENG Hui WANG Zhaomin XU Zizhong | 2007 | Nuclear Science and Techniques2007，18，5： | 2 |

| 10 | Effects of electric-acoustic and acoustic-electric conversions of transducers on acoustic logging signal显示文摘Based on an acoustic logging transmission network and the engineering pattern of a sliding wave in acoustic logging, analysis and calculations have been performed in a study of the effects of the electric-acoustic and acoustic-electric conversions of the transducers on the acoustic logging signal. The results show that acoustic-electric conversion through the transducer can cause not only a serious disturbance in the signal amplitude, but also an apparent transmission delay. For engineering applications, the amplitude variation and transmission delay must be accounted for in a practical analysis of the acoustic logging signal in rocks. The results also show that with enhanced understanding and proper justification, the error caused by the acoustic-electric conversion can be significantly reduced in evaluation of the cement bond quality of a cased well, and the accuracy of rock porosity calculated using the measured acoustic velocity can be increased. | FA Lin XIE WenYan TIAN Yong ZHAO MeiShan MA Li DONG DaQun | 2012 | Chinese Science Bulletin2012，57，11： | 2 |

| 13 | Green‑Solvent Processed Blade‑Coating Organic Solar Cells with an Efficiency Approaching 19%Enabled by Alkyl‑Tailored Acceptors显示文摘Power-conversion-efficiencies(PCEs)of organic solar cells(OSCs)in laboratory,normally processed by spin-coating technology with toxic halogenated solvents,have reached over 19%.However,there is usually a marked PCE drop when the bladecoating and/or green-solvents toward large-scale printing are used instead,which hampers the practical development of OSCs.Here,a new series of N-alkyl-tailored small molecule acceptors named YR-SeNF with a same molecular main backbone are developed by combining selenium-fused central-core and naphthalene-fused endgroup.Thanks to the N-alkyl engineering,NIR-absorbing YR-SeNF series show different crystallinity,packing patterns,and miscibility with polymeric donor.The studies exhibit that the molecular packing,crystallinity,and vertical distribution of active layer morphologies are well optimized by introducing newly designed guest acceptor associated with tailored N-alkyl chains,providing the improved charge transfer dynamics and stability for the PM6:L8-BO:YRSeNF-based OSCs.As a result,a record-high PCE approaching 19%is achieved in the blade-coating OSCs fabricated from a greensolvent o-xylene with high-boiling point.Notably,ternary OSCs offer robust operating stability under maximum-power-point tracking and well-keep>80%of the initial PCEs for even over 400 h.Our alkyl-tailored guest acceptor strategy provides a unique approach to develop green-solvent and blade-coating processed high-efficiency and operating stable OSCs,which paves a way for industrial development. | Hairui Bai Ruijie Ma Wenyan Su Top Archie Dela Pea Tengfei Li Lingxiao Tang Jie Yang Bin Hu Yilin Wang Zhaozhao Bi Yueling Su Qi Wei Qiang Wu Yuwei Duan Yuxiang Li Jiaying Wu Zicheng Ding Xunfan Liao Yinjuan Huang Chao Gao Guanghao Lu Mingjie Li Weiguo Zhu Gang Li Qunping Fan Wei Ma | 2023 | Nano-Micro Letters2023，15，12： | 1 |

| 15 | Approaching 19%efficiency and stable binary polymer solar cells enabled by a solidification strategy of solvent additive显示文摘Additives play a crucial role in enhancing the photovoltaic performance of polymer solar cells(PSCs).However,the typical additives used to optimize blend morphology of PSCs are still high boiling-point solvents,while their trace residues may reduce device stability.Herein,an effective strategy of“solidification of solvent additive(SSA)”has been developed to convert additive from liquid to solid,by introducing a covalent bond into low-cost solvent diphenyl sulfide(DPS)to synthesize solid dibenzothiophene(DBT)in one-step,which achieves optimized morphology thus promoting efficiency and device stability.Owing to the fine planarity and volatilization of DBT,the DBT-processed films achieve ordered molecular crystallinity and suitable phase separation compared to the additive-free or DPS-treated ones.Importantly,the DBT-processed device also possesses improved light absorption,enhanced charge transport,and thus a champion efficiency of 17.9%is achieved in the PM6:Y6-based PSCs with an excellent additive component tolerance,reproducibility,and stability.Additionally,the DBT-processed PM6:L8-BO-based PSCs are further fabricated to study the universality of SSA strategy,offering an impressive efficiency approaching19%as one of the highest values in binary PSCs.In conclusion,this article developed a promising strategy named SSA to boost efficiency and improve stability of PSCs. | Manjun Xiao Longfei Liu Yongdie Meng Baobing Fan Wenyan Su Conggui Jin Luocheng Liao Fan Yi Chao Xu Rui Zhang Alex K.-Y.Jen Wei Ma Qunping Fan | 2023 | Science China Chemistry2023，66，5： | 1 |
