| 2 | Enhancement of the Photoelectric Performance of Dye-sensitized Solar Cells by Sol-gel Modified TiO_2 Films显示文摘Modified TiO2 films have been prepared by combining commercial titania powders (Degussa P25) with sol-gel made by titanium chloride (Ti-sol). The result shows that clusters are formed by nanoparticles and large pores can be seen on the surface of the TiO2 films. The short circuit photocurrent density and photoelectric conversion efficiency of the solar cells are obviously enhanced compared with those without modification. The relationship between the photoelectric conversion efficiency and the amount of Ti-sol was investigated. With the addition of 30 wt% Ti-sol, the photoelectric conversion efficiency as high as 9.75% is achieved, increasing by 28.3% compared with the solar cells without modification. | Yunfeng Zhao Xiaojie Li Qiuping Li Changsheng Deng | 2011 | Journal of Materials Science & Technology2011，27，8： | 4 |
| 3 | Atmospheric carbonyls in a heavy ozone pollution episode at a metropolis in Southwest China:Characteristics,health risk assessment,sources analysis显示文摘Ambient carbonyls were continuously observed in the field during a heavy ozone pollution episode in Chengdu, China from August 4 to August 19, 2019, and the pollution characteristics, atmospheric photochemical reactivity, human health risk, and sources of carbonyls were analyzed. Fifteen carbonyls were quantified with average total mixing ratios of 20.38 ppbv Formaldehyde(9.86 ppbv), acetone(4.41 ppbv), and acetaldehyde(3.57 ppbv) were the three most abundant carbonyls. During the heavy ozone pollution episode, the concentration of carbonyls was found to be higher on pollution days than on the clean days, and relatively higher in the daytime, especially at noon on the pollution days. This was influenced by the intensity of photochemical reactions and precipitation. The “weekend effect” with the concentration of carbonyls was higher on the weekends than on the weekdays was pointed out. Formaldehyde, acetaldehyde and hexaldehyde were the dominant oxidative species during the observation. The carcinogenic and non-carcinogenic risk values of formaldehyde and acetaldehyde were higher on pollution days than on clean days, and these values were higher compared with those of other cities in China and abroad. Long-term exposure to these compounds should therefore be avoided. Diagnostic ratios and correlation analysis together with backward trajectory analysis showed that primary emission and secondary formation accounted 66%-76% and 24%–34% of carbonyls in Chengdu, respectively, with primary emission being the main sources of carbonyls, and carbonyls from the surrounding cities and emission from natural sources also had a significant contribution to the carbonyls in Chengdu. | Jiemeng Bao Hong Li Zhenhai Wu Xin Zhang Hao Zhang Yunfeng Li Jun Qian Junhui Chen Liqun Deng | 2022 | Journal of Environmental Sciences2022，34，3： | 1 |
| 4 | Low-bandgap conjugated polymers based on benzodipyrrolidone with reliable unipolar electron mobility exceeding 1 cm^(2) V^(-1)s^(-1)显示文摘The employment of an intrinsic quinoidal building block,benzodipyrrolidone(BDP),on constructing conjugated polymers(PBDP-2F and PBDP-2CN)with high electron mobility and unipolar transport characteristic in polyethylenimine ethoxylated(PEIE)modified organic field-effect transistors(OFETs)is reported.The intrinsic quinoidal characteristic and excellent coplanarity of BDP can lower the lowest unoccupied molecular orbital(LUMO)levels and improve ordered interchain packing of the resulting polymers in solid states,which are favorable for electron-injection and transport.By using PEIE as the interlayer to block the hole injection,unipolar n-type transport characteristics with high electron mobility of 0.58 and 1.01 cm^(2) V^(-1)s^(-1)were achieved by the OFETs based on PBDP-2F and PBDP-2CN,respectively.More importantly,the extracted mobilities are highly reliable with the reliability factor of above 80%.To the best of our knowledge,PBDP-2CN is the very first quinoid-based conjugated polymer with reliable electron mobility exceeding 1 cm^(2) V^(-1)s^(-1).This work represents a significant step in exploring intrinsic quinoidal CPs for application in n-channel OFETs and logic complementary circuits. | Mingqun Yang Tian Du Xuxia Zhao Xuelong Huang Langheng Pan Shuting Pang Haoran Tang Zhongxiang Peng Long Ye Yunfeng Deng Mingliang Sun Chunhui Duan Fei Huang Yong Cao | 2021 | Science China Chemistry2021，64，7： | 1 |

| 6 | Crosstalk between adipose-derived stem cells and chondrocytes:when growth factors matter显示文摘Adipose-derived stem cells(ASCs)and mesenchymal stem cells are promising for tissue repair because of their multilineage differentiation capacity.Our previous data confirmed that the implantation of mixed ASCs and chondrocytes into cartilage defects induced desirable in vivo healing outcomes.However,the paracrine action of ASCs on chondrocytes needs to be further elucidated.In this study,we established a co-culture system to achieve cell-to-cell and cell-to-tissue crosstalk and explored the soluble growth factors in both ASCs and chondrocytes supplemented with 1%fetal bovine serum to mimic the physiological microenvironment.In ASCs,we screened for growth factors by semi-quantitative PCR and quantitative real-time PCR and found that the expression of bone morphogenetic protein 2(BMP-2),vascular endothelial growth factor B(VEGFB),hypoxia inducible factor-1α(HIF-1α),fibroblast growth factor-2(FGF-2),and transforming growth factor-β1 significantly increased after co-culture in comparison with mono-culture.In chondrocytes,VEGFA was significantly enhanced after co-culture.Unexpectedly,the expression of collagen II and aggrecan was significantly down-regulated in the co-culture group compared with the mono-culture group.Meanwhile,among all the growth factors screened,we found that the BMP family members BMP-2,BMP-4,and BMP-5 were down-regulated and that VEGFB,HIF-1α,FGF-2,and PDGF were significantly decreased after co-culture.These results suggest that crosstalk between ASCs and chondrocytes is a pathway through the regulated growth factors that might have potential in cartilage repair and regeneration and could be useful for tissue engineering. | Juan Zhong Bin Guo Jing Xie Shuwen Deng Na Fu Shiyu Lin Guo Li Yunfeng Lin Xiaoxiao Cai | 2015 | Bone Research2015，3，4： | 1 |
| 7 | Calculation aided miscibility manipulation enables highly efficient polythiophene:nonfullerene photovoltaic cells显示文摘Polythiophenes,with merits of low cost and high scalability of synthesis,have received growing interest in organic solar cells.To date,the best-performing polythiophene:nonfullerene solar cells exhibit typical power conversion efficiencies (PCEs) of 10%–12%,which is much lower than those employing PM6-and D18-type polymers.This inferior performance is mostly limited by the improper miscibility between polythiophene and acceptors.Efforts on engineering the molecular structure to systematically tune the miscibility are required.With the aid of group contribution calculations,the miscibility of polythiophene:nonfullerene blend system was finely tuned by varying the ratios of siloxane-terminated chains and alkyl chains in ester-substituted polythiophenes through random copolymerization.Based on a series of the polythiophene and nonfullerene acceptors,the detailed analysis of blend miscibility and performance reveals a surprising anticorrelation between the Flory-Huggins interaction parameter (χ_(aa)) and the optimal time of solvent vapor annealing for device performance across these systems.Primarily due to the slightly higher χ_(aa),the blend of PDCBT-Cl-Si5 and ITIC-Th1 results in a record-high PCE of 12.85%in polythiophene:nonfullerene solar cells.The results not only provide a calculation-guided approach for molecular design but also prove that precise control of the miscibility is an effective way to design high-performance polythiophene:nonfullerene blends and beyond. | Qi Wang Miaomiao Li Zhongxiang Peng Nigel Kirby Yunfeng Deng Long Ye Yanhou Geng | 2021 | Science China Chemistry2021，64，3： | 1 |
| 8 | Enhanced n-Type Thermoelectric Performance of Conjugated Polymers Based on an Indandione-Terminated Quinoidal Unit through Comonomer Optimization显示文摘Comprehensive Summary Conjugated polymers(CPs)containing quinoidal units are promising in n-type organic thermoelectric materials because of their deep-positioned lowest unoccupied molecular orbital(LUMO)energy levels and planar conjugated backbones.Herein,three CPs have been synthesized by copolymerizing an indandione-terminated quinoidal unit with bithiophene derivatives.Owning to the high electron affinity of the indandione-terminated quinoidal unit,all polymers showed deep LUMO energy levels below-4.10 eV.Incorporating electron-withdrawing substituents(F or CN)on the bithiophene comonomer can further downshift the LUMO energy levels.As a result,a more efficient n-doping process can be realized when employing 4-(2,3-dihydro-1,3-dimethyl-1H-benzimidazol-2-yl)-N,N-dimethylbenzenamine(N-DMBI)as the dopant.Ultimately,the polymer with CN substituents delivered the best thermoelectric performance with a power factor of up to 2.14μW·m^(−1)·K^(−2),because it possessed the lowest LUMO energy level among the three CPs.This work highlights that the modulation of LUMO energy level is an effective strategy to optimize the thermoelectric performance of CPs. | Tian Du Yingying Liu Yunfeng Deng Yanhou Geng | 2023 | Chinese Journal of Chemistry2023，41，7： | 1 |

| 11 | Climate warming restructures seasonal dynamics of grassland soil microbial communities显示文摘Soil microbial community's responses to climate warming alter the global carbon cycle.In temperate ecosystems,soil microbial communities function along seasonal cycles.However,little is known about how the responses of soil microbial communities to warming vary when the season changes.In this study,we investigated the seasonal dynamics of soil bacterial community under experimental warming in a temperate tall‐grass prairie ecosystem.Our results showed that warming significantly(p=0.001)shifted community structure,such that the differences of microbial communities between warming and control plots increased nonlinearly(R^(2)=0.578,p=0.021)from spring to winter.Also,warming significantly(p<0.050)increased microbial network complexity and robustness,especially during the colder seasons,despite large variations in network size and complexity in different seasons.In addition,the relative importance of stochastic processes in shaping the microbial community decreased by warming in fall and winter but not in spring and summer.Our study indicates that climate warming restructures the seasonal dynamics of soil microbial community in a temperate ecosystem.Such seasonality of microbial responses to warming may enlarge over time and could have significant impacts on the terrestrial carbon cycle. | Xue Guo Mengting Yuan Jiesi Lei Zhou Shi Xishu Zhou Jiabao Li Ye Deng Yunfeng Yang Liyou Wu Yiqi Luo James MTiedje Jizhong Zhou | 2022 | mLife2022，1，3： | 1 |

| 13 | Semi-interpenetrating polymer networks toward sulfonated poly(ether ether ketone) membranes for high concentration direct methanol fuel cell显示文摘Low methanol permeability of proton exchange membranes (PEMs) is greatly important for direct methanol fuel cells (DMFCs). Here, sulfonated poly (ether ether ketone) (SPEEK) based semiinterpenetrating polymer networks (semi-IPNs) are successfully prepared by interpenetrating SPEEK into the in-situ synthesized crosslinking networks. The polymeric networks are formed by the covalent bonds between bromobenzyl groups of bro mo methylated poly (phenylene oxide) and amine groups of diamine linkers as well as the ionic bonds between amine species and sulfonated groups. Two linkers without and with sulfonated groups are applied to fabricate the semi-IPNs. The core properties of the membranes, like phase separation, water uptake, proton conductivity and methanol permeability, are systematically studied and compared. The DMFCs assembled by using the semi-IPN membranes display better performance than Nafion 117 in high concentration methanol solutions. The present work provides a facile way to prepare PEMs with enhanced DMFC performance. | Xupo Liu Yunfeng Zhang Shaofeng Deng Cuicui Li Jiaming Dong Jiaying Wang Zehui Yang Deli Wang Hansong Cheng | 2019 | Chinese Chemical Letters2019，30，2： | 1 |

| 15 | Efficient TurboID-based proximity labelling method for identifying terminal sialic acid glycosylation in living cells显示文摘TurboID,a proximity labelling method based on mutant biotin ligase,is an efficient new technique for recognizing protein-protein interactions and has been successfully applied to living cells.Sialic acid is typically the terminal monosaccharide attached to many glycoproteins and plays many important roles in many biological processes.However,the lack of enrichment methods for terminal sialic acid glycosylation in vivo hinders the identification and analysis of this glycosylation.Here,we introduce TurboID to identify terminal sialic acid glycosylation in living cells.SpCBM,the carbohydrate-binding domain of sialidase from Streptococcus pneumoniae,is fused with TurboID and overexpressed in HeLa cells.After streptavidin-based purification and detection by mass spectrometry,31 terminal sialic acid N-glycosylated sites and 1359 putative terminal sialic acid glycosylated proteins are identified,many of which are located in the cytoplasm and nucleus. | Wu Liu Yunfeng Long Yongfen Bao Yang Li Mengxue Deng Xiuyi Yang He Zhu Yanting Su | 2022 | Acta Biochimica et Biophysica Sinica2022，54，12： | 0 |
| 16 | Fine Individual Selection of Camellia pitardii in Pengshui County显示文摘In order to select improved varieties, a study on the fine individual selection was carried out in Pengshui County, Chongqing Province. For 14 fine individuals with high and stable yield preliminarily screened, eight factors(fruit height, fruit diameter, pericarp thickness, fresh fruit weight, fresh seed weight, dry seed weight, dry seed yield and fresh seed yield) related to yield were selected to perform principal component analysis, and based on comprehensive scores and oil contents, five fine individuals(Longshe Town 7, 8, 12, 17 and Shaoqing Street 2) of Camellia pitardii were determined. These fine individuals have a better performance. | Xiaomei TAN Rong ZHANG Yunfeng GUAN Xiangshun DENG Ya WANG | 2019 | Agricultural Biotechnology2019，8，2： | 0 |
| 17 | High T_(g) Polymer Insulator Yields Organic Photovoltaic Blends with Superior Thermal Stability at 150℃显示文摘Record-breaking organic solar cells(OSCs)based on blends of polymer donors and small molecule acceptors often show undesirable degradati on,which severely precludes their practical use.Herei n,we demonstrate a facile and cost-effective approach to con struct thermally stable OSCs at 150℃ by incorporating a small amount of a polymer insulator polyacenaphthylene(PAC)with high glass-transition temperature over 230℃ into polymer:acceptor blends.The model PTB7-Th:EH-IDTBR blend with 10 wt%PAC maintained above 85%of its initial efficiency upon continuous heating at 150℃ for over 800 h,while the efficiency of the blend without PAC sharply dropped by 70%after-300 h.Owing to high miscibility with acceptors,PAC confines the motion of the acceptor molecules and suppresses the acceptor crystallization at elevated temperatures,leading to significantly improved stability.Importantly,the effectiveness of this blending approach was also validated in many other OSC systems,showing great potential for achieving high-performance thermally stable electronics. | Fei Chen Ying Zhang Qi Wang Mengyuan Gao Nigel Kirby Zhongxiang Peng Yunfeng Deng Miaomiao Li Long Ye | 2021 | Chinese Journal of Chemistry2021，39，9： | 0 |
| 18 | Dithienocarbazole- and benzothiadiazole-based donor-acceptor conjugated polymers for bulk heterojunction polymer solar cells显示文摘Donor-acceptor(D-A)-conjugated polymers P(BT-C1)and P(BT-C2),with dithieno[2,3-b;7,6-b]carbazole(C1)or dithieno[3,2-b;6,7-b]carbazole(C2)as D-unit and benzothiadiazole(BT)as A-unit,were synthesized.The optical bandgaps of the polymers are similar(1.84 and 1.88 e V,respectively).The structures of donor units noticeably influence the energy levels and backbone curvature of the polymers.P(BT-C1)shows a large backbone curvature;its highest occupied molecular orbital(HOMO)energy level is 5.18 e V,whereas P(BT-C2)displays a pseudo-straight backbone and has a HOMO energy level of 5.37 e V.The hole mobilities of the polymers without thermal annealing are 1.9×10 3 and 2.7×10 3 cm2 V 1 s 1 for P(BT-C1)and P(BT-C2),respectively,as measured by organic thin-film transistors(OTFTs).Polymer solar cells using P(BT-C1)and P(BT-C2)as the donor and phenyl-C71-butyric acid methyl ester(PC71BM)as the acceptor were fabricated.Power conversion efficiencies(PCEs)of 4.9%and 5.0%were achieved for P(BT-C1)and P(BT-C2),respectively.The devices based on P(BT-C2)exhibited a higher Voc due to the deeper HOMO level of the polymer,which led to a slightly higher PCE. | Ziqing Rong Yunfeng Deng Zhiyuan Xie Yanhou Geng Fosong Wang | 2015 | Science China Chemistry2015，58，2： | 0 |
| 19 | Mapping a stable adult-plant stripe rust resistance QTL on chromosome 6AL in Chinese wheat landrace Yibinzhuermai显示文摘Stripe rust,caused by Puccinia striiformis f.sp.tritici(Pst),is one of the most important diseases threatening the yield and stability of wheat production in China and many other countries.Identification and utilization of new genes for durable stripe rust resistance are important for ongoing control of this disease.The objectives of this study were to identify quantitative trait loci(QTL)associated with adult-plant stripe rust resistance in the Chinese wheat landrace Yibinzhuermai(YBZR)and to provide wheat breeders with new sources of potentially durable resistance.A total of 117 recombinant inbred lines(RILs)(F5:8)derived from a cross between YBZR and highly susceptible cultivar Taichung 29(TC29)were assessed for stripe rust severity in field experiments at Wenjiang in 2016 and 2017 and Chongzhou in 2016,2017,2018,and 2019 in Sichuan following inoculation with a mixture of current Pst races.The RILs were genotyped using the Wheat55K single nucleotide polymorphism(SNP)array.Three QTL were identified on chromosome arms 6AL,5BL and 7DS.QYr.YBZR-6AL and QYr.YBZR-7DS conferred major effects in all field environments,explaining 10.6%to 14.7%and 11.5%to 21.2%of phenotypic variation,respectively.The QTL on 5BL and 7DS likely correspond to previously known QTL,whereas QYr.YBZR-6AL is probably novel.Haplotype analysis revealed that the resistance allele at QYr.YBZR-6AL was present in 2.8%of 324 Chinese wheat landraces.SNP markers closely linked with QYr.YBZR-6AL were converted to kompetitive allele-specific PCR markers and validated in the RIL population and a subset of 92 wheat cultivars.QYr.YBZR-6AL and its markers should be useful in breeding programs to improve the level and durability of stripe rust resistance. | Mei Deng Li Long Yukun Cheng Fangjie Yao Fangnian Guan Yuqi Wang Hao Li Zhien Pu Wei Li Qiantao Jiang Yuming Wei Jian Ma Houyang Kang Pengfei Qi Jirui Wang Youliang Zheng Yunfeng Jiang Guoyue Chen | 2022 | The Crop Journal2022，10，4： | 0 |
| 20 | Washing-free chemiluminescence immunoassay for rapid detection of cardiac troponin Ⅰ in whole blood samples显示文摘Chemiluminescence immunoassay(CLⅠA) has always been a great challenge in detecting cardiac troponin Ⅰ(c Tn Ⅰ) in whole blood samples without centrifugation because of the interference of red blood cells and low sensitivity. Ⅰn this study, the antigens and erythrocytes in the blood were captured by the antibodies immobilized on the magnetic particles, recognized by another biotinconjugated c Tn Ⅰ antibody and detected by streptavidin/acridine aster-conjugated polychloromethylstyrene microspheres(PCMS). After magnetic separation, the supernatant was transferred and measured. No significant difference was noted between the c Tn Ⅰ concentrations of the serum samples,plasma samples and whole blood. The prepared PCMS provided more functional areas to conjugate streptavidin and acridinium ester, so the immunoassay has highly sensitive, the limits of blank at0.012 ng/mL, and functional sensitivity at 0.019 ng/mL with a CV of 20%, and 0.058 ng/mL with a CV of 10%. Total precision of any sample type ranged from 2.62%~5.67%. The assay was linear over the studied range of 0.01-50.00 ng/mL, and no hook effect was found when c Tn Ⅰ concentrations reached 1900 ng/mL. No significant interference was noted with the potential endogenous interfering substances. Compared with the commercial kit(Abbott assay kit), the correlation coefficient was 0.9859. A washing-free CLⅠA was established for the rapid detection of c Tn Ⅰ in human whole blood, using erythrocyte capture antibodies-conjugated magnetic nanoparticles for eliminating the influence of erythrocytes and PCMS for signal amplification, which showed great potential in clinical application. | Huan Zhao Enben Su Li Huang Yunfeng Zai Yuan Liu Zhu Chen Song Li Lian Jin Yan Deng Nongyue He | 2022 | Chinese Chemical Letters2022，33，2： | 0 |
