| 1 | Review of blue perovskite light emitting diodes with optimization strategies for perovskite film and device structure显示文摘Perovskite light emitting diodes(PeLEDs)have attracted considerable research attention because of their external quantum efficiency(EQE)of>20%and have potential scope for further improvement.However,compared to red and green PeLEDs,blue PeLEDs have not been extensively investigated,which limits their commercial applications in the fields of luminance and full-color displays.In this review,blue-PeLED-related research is categorized by the composition of perovskite.The main challenges and corresponding optimization strategies for perovskite films are summarized.Next,the novel strategies for the design of device structures of blue PeLEDs are reviewed from the perspective of transport layers and interfacial layers.Accordingly,future directions for blue PeLEDs are discussed.This review can be a guideline for optimizing perovskite film and device structure of blue PeLEDs,thereby enhancing their development and application scope. | Zongtao Li Kai Cao Jiasheng Li Yong Tang Xinrui Ding Binhai Yu | 2021 | Opto-Electronic Advances2021，4，2： | 3 |
| 2 | Intra-abdominal aortic balloon occlusion in the management of placenta percreta显示文摘Background:Massive bleeding is the main concern for the management of placenta percreta(PP).Intra-abdominal aortic balloon occlusion(IABO)is one method for pelvic devascularization,but the efficacy of IABO is uncertain.This study aims to investigate the outcomes of IABO in PP patients.Methods:We retrospectively reviewed the clinical data of PP cases from six tertiary centers in China between January 2011 and December 2015.PP cases with/without the use of IABO were analyzed.Propensity score matching analysis was performed to reduce the effect of selection bias.Postpartum hemorrhage(PPH)and the rate of hysterectomy,as well as neonatal outcomes,were analyzed.Results:One hundred and thirty-two matched pairs of patients were included in the final analysis.Compared with the control group,maternal outcomes,including PPH(68.9%vs.87.9%,χ^(2)=13.984,P<0.001),hysterectomy(8.3%vs.65.2%,χ^(2)=91.672,P<0.001),and repeated surgery(1.5%vs.12.1%,χ^(2)=11.686,P=0.001)were significantly reduced in the IABO group.For neonatal outcomes,Apgar scores at 1 minute(8.67±1.79vs.8.53±1.68,t=-0.638,P=0.947)and 5 minutes(9.43±1.55vs.9.53±1.26,t=0.566,P=0.293)were not significantly different between the two groups.Conclusions:IABO can significantly reduce blood loss,hysterectomies,and repeated surgeries.This procedure has not shown harmful effects on neonatal outcomes. | Weiran Zheng Ruochong Dou Jie Yan Xinrui Yang Xianlan Zhao Dunjin Chen Yuyan Ma Weishe Zhang Yiling Ding Ling Fan Huixia Yang | 2022 | Chinese Medical Journal2022，，4： | 2 |
| 3 | Enhanced optical and thermal performance of white light-emitting diodes with horizontally layered quantum dots phosphor nanocomposites显示文摘Due to their good color rendering ability, white light-emitting diodes(WLEDs) with conventional phosphor and quantum dots(QDs) are gaining increasing attention. However, their optical and thermal performances are still limited especially for the ones with QDs-phosphor mixed nanocomposites. In this work, we propose a novel packaging scheme with horizontally layered QDs-phosphor nanocomposites to obtain an enhanced optical and thermal performance for WLEDs. Three different WLEDs, including QDs-phosphor mixed type, QDsoutside type, and QDs-inside type, were fabricated and compared. With 30 wt. % phosphor and 0.15 wt. % QDs nanocomposite, the QDs-outside type WLED shows a 21.8% increase of luminous efficiency, better color rendering ability, and a 27.0% decrease of the maximum nanocomposite temperature at 400 mA, compared with the mixed-type WLED. The reduced re-absorption between phosphor and QDs is responsible for the performance enhancement when they are separated. However, such reduced absorption can be traded off by the improper layered configuration, which is demonstrated by the worst performance of the QDs-inside type. Further, we demonstrate that the higher energy transfer efficiency between excitation light and nanocomposite in the QDs-outside type WLED is the key reason for its enhanced optical and thermal performance. | SHUDONG Yu YONG TANG ZONGTAO LI KAIHANG CHEN XINRUI DING AND BINHAI Yu | 2018 | Photonics Research2018，6，2： | 2 |
| 4 | Direct conversion of mouse astrocytes into neural progenitor cells and specific lineages of neurons显示文摘Background:Cell replacement therapy has been envisioned as a promising treatment for neurodegenerative diseases.Due to the ethical concerns of ESCs-derived neural progenitor cells(NPCs)and tumorigenic potential of iPSCs,reprogramming of somatic cells directly into multipotent NPCs has emerged as a preferred approach for cell transplantation.Methods:Mouse astrocytes were reprogrammed into NPCs by the overexpression of transcription factors(TFs)Foxg1,Sox2,and Brn2.The generation of subtypes of neurons was directed by the force expression of cell-type specific TFs Lhx8 or Foxa2/Lmx1a.Results:Astrocyte-derived induced NPCs(AiNPCs)share high similarities,including the expression of NPC-specific genes,DNA methylation patterns,the ability to proliferate and differentiate,with the wild type NPCs.The AiNPCs are committed to the forebrain identity and predominantly differentiated into glutamatergic and GABAergic neuronal subtypes.Interestingly,additional overexpression of TFs Lhx8 and Foxa2/Lmx1a in AiNPCs promoted cholinergic and dopaminergic neuronal differentiation,respectively.Conclusions:Our studies suggest that astrocytes can be converted into AiNPCs and lineage-committed AiNPCs can acquire differentiation potential of other lineages through forced expression of specific TFs.Understanding the impact of the TF sets on the reprogramming and differentiation into specific lineages of neurons will provide valuable strategies for astrocyte-based cell therapy in neurodegenerative diseases. | Kangmu Ma Xiaobei Deng Xiaohuan Xia Zhaohuan Fan Xinrui Qi Yongxiang Wang Yuju Li Yizhao Ma Qiang Chen Hui Peng Jianqing Ding Chunhong Li Yunlong Huang Changhai Tian Jialin C.Zheng | 2018 | Translational Neurodegeneration2018，7，1： | 2 |
| 5 | Plowing-Extrusion Processes and Performance of Functional Surface Structures of Copper Current Collectors for Lithium-Ion Batteries显示文摘Most copper current collectors for commercial lithium-ion batteries(LIBs)are smooth copper foils,which cannot form a stable and effective combination with electrode slurry.They are likely to deform or fall off after long-term operation,resulting in a sharp decline in battery performance.What is worse is that this condition inevitably causes internal short circuits and thus brings about security risks.In this study,a process route of fabricating the functional surface structures on the surface of a copper collector for LIBs by twice-crisscross micro-plowing(TCMP)is proposed,which provides a new idea and an efficient method to solve the above problems from the perspective of manufacturing.The finite element simulation of TCMP combined with the cutting force test and morphological characterization is conducted to verify the forming mechanism of the surface structures on a copper sheet and its relationship with the processing parameters.The influence of several key processing parameters on the surface characteristics of the copper sheet is comprehensively explored.A series of functions is tested to obtain the optimal parameters for performance improvement of the current collector.Results show that the structured copper sheet with the cutting distance of 250μm,cutting depth of 80μm,and cutting crossing angle of 90°enables the best surface features of the current collector;the contact angle reaches 0°,the slurry retention rate is up to 89.2%,and the friction coefficient reaches 0.074.The battery using the as-prepared structured copper sheet as the current collector produces a specific capacity of 318.6 mAh/g after 50 cycles at a current density of 0.2 C,which is 132.7%higher than the one based on a smooth surface.The capacity reversibility of the sample with the new current collector is much better than that of the traditional samples,yielding a lower impedance. | Chun Wang Wei Yuan Yu Chen Bote Zhao Yong Tang Shiwei Zhang Xinrui Ding Jun He Songmao Chen Baoyou Pan Mingyue Chen | 2022 | Nanomanufacturing and Metrology2022，5，4： | 2 |

| 7 | Composite Eu-MOF@CQDs“off&on”ratiometric luminescent probe for highly sensitive chiral detection of l-lysine and 2-methoxybenzaldehyde显示文摘The high amount of l-lysine can increase the potential risk of cardiovascular disease.Additionally,2-methoxy benzaldehyde(2-MB)has high toxicity and can easily pollute the environment.In this work,carbon quantum dots(CQDs)can be encapsulated into Eu-BTB(H_(3)BTB=1,3,5-tri(4-carboxyphenyl)benzene),forming the multi-emission composite material Eu-BTB@CQDs.It has two emissions peaks(617 nm for Eu and 470 nm for CQDs).Eu-BTB@CQDs can be applied as bi-functional ratiometric“off&on”luminescent sensor for l-lysine and 2-MB with high sensitivity and selectivity,the low limit of detection(LOD)for l-lysine is 3.68μmol/L and for 2-MB is 0.54μmol/L,respectively.Additionally,Eu-BTB@CQDs can quantitatively discriminate l-lysine in the mixed d-and l-lysine water solutions(five different concentrations ratio of l/d-lysine has been set)makes the chiral detection of l-lysine are more meaningful.On the other hand,Eu-BTB@CQDs also can detect 2-MB over 4-methoxybenzaldehyde(4-MB)with high selectivity.Further the detection of 2-MB and l-lysine in the lake water real samples with the reasonable recovery rate.Finally,the detection mechanisms for l-lysine and 2-MB were also investigated and discussed in detail. | Yupeng Jiang Xinhui Fang Ziqing Zhang Xiaomeng Guo Jianzhong Huo Qian Wang Yuanyuan Liu Xinrui Wang Bin Ding | 2023 | Chinese Chemical Letters2023，34，11： | 0 |

| 9 | Water-stable CsPbBr3 perovskite quantum-dot luminous fibers fabricated by centrifugal spinning for dual white light illumination and communication显示文摘Lead halide perovskite quantum dots(PQDs)display remarkable photoelectric performance.However,defects such as weak stability in air and water environments limit the development of lead halide PQDs in solid-state light applications.Herein,centrifugal spinning is used for the fabrication of stable luminous CsPbBr3 PQD nanofibers.After immersion in water for 11 months,the PQD fibers still maintained considerable photoluminescence quantum yield,showing high stability in hostile environments.The water-stability mechanism of the fibers can be explained by the changing defect density,crystal growth of PQDs,and the molecular transformation at the fiber surface.The white LED based on the CsPbBr3 fibers exhibits satisfying color gamut performance(128%of National Television System Committee).Due to the short photoluminescence lifetime of CsPbBr3 PQDs,the communication potential is also considered.The CsPbBr3 fibers obtained by centrifugal spinning present a bandwidth of 11.2 MHz,showing promising performance for solid-state light and visible light communication applications. | BINHAI YU SHUNMING LIANG FENGYI ZHANG ZONGTAO LI BIN LIU XINRUI DING | 2021 | Photonics Research2021，9，8： | 0 |
| 10 | Rational design and low-cost fabrication of multifunctional separators enabling high sulfur utilization in long-life lithium-sulfur batteries显示文摘The lithium-sulfur(Li-S)battery with an ultrahigh theoretical energy density has emerged as a promising rechargeable battery system.However,the practical applications of Li-S batteries are severely plagued by the sluggish reaction kinetics of sulfur species and notorious shuttling of soluble lithium polysulfides(LiPSs)intermediates that result in low sulfur utilization.The introduction of functional layers on separators has been considered as an effective strategy to improve the sulfur utilization in Li-S batteries by achieving effective regulation of LiPSs.Herein,a promising self-assembly strategy is proposed to achieve the low-cost fabrication of hollow and hierarchically porous Fe_(3)O_(4)nanospheres(p-Fe_(3)O_(4)-NSs)assembled by numerous extremely-small primary nanocrystals as building blocks.The rationally-designed p-Fe_(3)O_(4)-NSs are utilized as a multifunctional layer on the separator with highly efficient trapping and conversion features toward LiPSs.Results demonstrate that the nanostructured p-Fe_(3)O_(4)-NSs provide chemical adsorption toward LiPSs and kinetically promote the mutual transformation between LiPSs and Li_(2)S_(2)/Li_(2)S during cycling,thus inhibiting the LiPSs shuttling and boosting the redox reaction kinetics via a chemisorption-catalytic conversion mechanism.The enhanced wettability of the p-Fe_(3)O_(4)-NSs-based separator with the electrolyte enables fast transportation of lithium ions.Benefitting from these alluring properties,the functionalized separator with p-Fe_(3)O_(4)-NSs endows the battery with an admirable rate performance of 877 mAh g^(−1)at 2 C,an ultra-durable cycling performance of up to 2176 cycles at 1 C,and a promising areal capacity of 4.55 mAh cm^(−2)under high-sulfur-loading and lean-electrolyte conditions(4.29 mg cm^(−2),electrolyte/ratio:8μl mg^(−1)).This study will offer fresh insights on the rational design and low-cost fabrication of multifunctional separator to strengthen electrochemical reaction kinetics by regulating LiPSs conversion for developing efficient and long-life Li-S batteries. | Xiaoqing Zhang Wei Yuan Honglin Huang Ming Xu Yu Chen Bote Zhao Xinrui Ding Shiwei Zhang Yong Tang Longsheng Lu | 2023 | International Journal of Extreme Manufacturing2023，5，1： | 0 |
| 11 | Annealing Effect of ZnO on the Performance of Inverted Organic Photovoltaic Devices显示文摘ZnO nanoparticles films were prepared via sol-gel process and incorporated into inverted organic photovoltaic devices with a structure of ITO/ZnO/P3HT:PCBM/MoO_3/Ag,in which ZnO film served as an electron selective layer.The effects of annealing temperature of ZnO film on the device performance were investigated.When the annealing temperature was 300 ℃,a well-arranged ZnO thin film was obtained,and the optimized device had doubled short circuit current density(J_(SC)) and seven-fold higher power conversion efficiency(PCE)compared to the devices without ZnO film.This improvement could be attributed to the enlarged interfacial area of ZnO/active layer and better energy band matching which causes an efficient electron extraction and a decreased interface energy barrier.At particularly high annealing temperature,dramatically increased sheet resistance of indium tin oxide(ITO) was found to cause PCE deterioration.Our finding indicates that it is highly important to investigate both morphology and electrical effects for understanding and optimizing organic photovoltaic(OPV) performance. | Wenjing Qin Guojing Ding Xinrui Xu Liying Yang Shougen Yin | 2014 | Journal of Materials Science & Technology2014，30，2： | 0 |
