| 1 | Generating long-wavelength absorption bands with enhanced deep red fluorescence and photothermal performance in fused carbon dots aggregates显示文摘Carbon dots(CDs)with long-wavelength absorptions and emissions are highly desired for biological applications.Herein,we report a new supra-CDs strategy to construct long-wavelength absorption bands based on fused CDs aggregates(f-CDAs)through a concentration-induced interparticle dehydration process among green emissive CDs(r-CDs)under solvothermal treatment.The obtained fused f-CDAs exhibit an obvious absorption band in 550-700 nm and significantly enhanced deep red fluorescence in N,N-dimethylformamide with photoluminescence quantum yields of 15.6% and high photothermal conversion efficiency up to 26.1%in water.Benefiting from the high photothermal performance,in vivo tumor photothermal therapy has been realized via intratumoral injection of f-CDAs under 655 nm laser irradiated at 0.5 W/cm^(2). | Jun Wu Josh Haipeng Lei Bingchen He Chu-Xia Deng Zikang Tang Songnan Qu | 2021 | Aggregate2021，2，6： | 1 |
| 2 | Polyetherimide functionalized carbon dots with enhanced red emission in aqueous solution for bioimaging显示文摘Red emissive carbon dots(CDs)are highly desired for biological applications.However,serious luminescence quenching of red emissive CDs in aqueous solution greatly hinders their application in high performance biological imaging.Herein,we reported a facile strategy to realize enhanced red emission of CDs in aqueous solution by surface modification with polyetherimide(PEI)via microwave heating method.High photoluminescence quantum yield(PLQY)of 25%was realized from the PEI functionalized CDs(CDs@PEI)in aqueous solution.The proposed PEI functionalization strategy not only protects the red emission against water molecules quenching,but also reverses the surface charges from negativity to positivity to promote cellular uptake of CDs,leading to clear cell imaging in red fluorescence region.More important,CDs@PEI exhibits much better photostability than commercial red emissive dye(MitoT racker red)in cell fluorescent imaging.Potential application of CDs@PEI on fast staining of cells for clonogenic assay has also been demonstrated. | Liming Wang Bingzhe Wang Enshan Liu Yunyang Zhao Bingchen He Chunfei Wang Guichuan Xing Zikang Tang Yinning Zhou Songnan Qu | 2022 | Chinese Chemical Letters2022，33，8： | 0 |
| 3 | Influence of Reading Behavior of Entrepreneurs on Their Entrepreneurial Performance: Empirical Study of Chongqing显示文摘In the context of economic downward and industrial structural adjustment,cultural level of entrepreneurs exerts direct influence on entrepreneurial results,while reading behavior of entrepreneurs is closed connected with cultural level of entrepreneurs. Therefore,it is of utmost importance to analyze the relation between reading behavior and entrepreneurial performance. Based on the survey data of 200 enterprises in one- hour economic circle of Chongqing,this paper analyzed three dimensions of reading behavior of entrepreneurs: reading subjects,reading media,and reading environment. It analyzed the relation between these three indicators and entrepreneurial performance. It further divided entrepreneurial performance into survival performance and financial performance. Finally,it came up with following conclusions:( i) good reading exerts significantly positive effect on survival performance of entrepreneurial enterprises;( ii) suitable reading environment plays a positive role in financial performance of entrepreneurial enterprises. | Bingchen SUN Xi HE | 2016 | Asian Agricultural Research2016，8，5： | 0 |
| 4 | Stabilizing SEI by cyclic ethers toward enhanced K^(+) storage in graphite显示文摘The poor cycling stability of graphite in traditional ester electrolyte limits its applications as anodes for potassium ion batteries(KIBs).Herein,we demonstrate that the introduction of cyclic ether co-solvents into ester electrolytes can remarkably enhance the cycling stability of graphite anodes.The graphite anode in ester electrolyte with cyclic ether could achieve a reversible capacity of 196.1 m Ah g^(-1) after 100 cycles at 0.3 C(1 C=280 m A g^(-1)),about three times higher than those in ester electrolytes with or without linear ether.Compared with the SEI formed in ester electrolytes,the addition of tetrahydrofuran promotes the generation of K_(2)CO_(3) and ethylene oxide oligomers(PEO),of which the K_(2)CO_(3) is expected to be more conductive and PEO is mechanically robust.The more uniform,conductive and stable solid electrolyte interphases(SEIs)on graphite in electrolytes with cyclic ethers contribute to the enhancement of the electrochemical performances of graphite.This work provides a novel design of commercialized electrolytes to achieve high-performance anodes for KIBs,which potentially accelerates the development of KIBs. | Jiesong Zhang Jian-Fang Wu Zixing Wang Ying Mo Wang Zhou Yufan Peng Bingchen He Kuikui Xiao Shi Chen Chaohe Xu Jilei Liu | 2022 | Journal of Energy Chemistry2022，31，8： | 0 |
