| 1 | Flexible ITO-free organic solar cells over 10% by employing drop-coated conductive PEDOT:PSS transparent anodes显示文摘Highly conductive poly(3,4-ethylenedioxythiophene):poly(styrene-sulfonic acid)(PEDOT:PSS) has been explored to fabricate flexible and stretchable conductors. Generally, PEDOT:PSS transparent anodes are prepared by spin-coating method. In this article, we adopt a method by dropping PEDOT:PSS aqueous solution on the PET plastic substrate to fabricate flexible electrodes. Compared with spin coating, drop-coating is simple and cost-effective with large-area fabrications. Through this method, we fabricated highly transparent conductive electrodes and systematically studied their electrical, optical, morphological and mechanical properties. With dimethyl sulfoxide/methanesulfonic acid(DMSO/MSA) treated PEDOT:PSS electrode,bendable devices based on non-fullerene system displayed an open-circuit voltage of 0.925 V, a fill factor of 70.74%, and a high power conversion efficiency(PCE) of 10.23% under 100 mW cm^(-2) illumination, which retained over 80% of the initial PCE value after 1000 bending cycles. Based on the findings, drop-coated PEDOT:PSS electrodes exhibited high suitability for the development of large-area and high-efficiency printed solar cell modules in the future. | Huiqin Cui Wei Song Billy Fanady Ruixiang Peng Jianfeng Zhang Jiaming Huang Ziyi Ge | 2019 | Science China Chemistry2019，62，4： | 3 |
| 2 | Potential therapeutic effects and applications of Eucommiae Folium in secondary hypertension显示文摘Eucommiae Folium(EF),a traditional Chinese medicine,has been used to treat secondary hypertension,including renal hypertension and salt-sensitive hypertension,as well as hypertension caused by thoracic aortic endothelial dysfunction,a high-fat diet,and oxidized low-density lipoprotein.The antihypertensive components of EF are divided into four categories:flavonoids,iridoids,lignans,and phenylpropanoids,such as chlorogenic acid,geniposide acid and pinoresinol diglucoside.EF regulates the occurrence and development of hypertension by regulating biological processes,such as inhibiting inflammation,regulating the nitric oxide synthase pathway,reducing oxidative stress levels,regulating endothelial vasoactive factors,and lowering blood pressure.However,its molecular antihypertensive mechanisms are still unclear and require further investigation.In this review,by consulting the relevant literature on the antihypertensive effects of EF and using network pharmacology,we summarized the active ingredients and pharmacological mechanisms of EF in the treatment of hypertension to clarify how EF is associated with secondary hypertension,the related components,and underlying mechanisms.The results of the network pharmacology analysis indicated that EF treats hypertension through a multicomponent,multi-target and multi-pathway mechanism.In particular,we discussed the role of EF targets in the treatment of hypertension,including epithelial sodium channel,heat shock protein70,rhoassociated protein kinase 1,catalase,and superoxide dismutase.The relevant signal transduction pathways,the ras homolog family member A(RhoA)/Rho-associated protein kinase(ROCK)and nicotinamide adenine dinucleotide phosphate(NADPH)oxidase/eNOS/NO/Ca^(2+)pathways,are also discussed. | Mengyuan Li Yanchao Zheng Sha Deng Tian Yu Yucong Ma Jiaming Ge Jiarong Li Xiankuan Li Lin Ma | 2022 | Journal of Pharmaceutical Analysis2022，12，5： | 2 |
| 3 | ITO/Cu multilayer electrodes for high-brightness electrochromic displays显示文摘Fabry-Perot(F-P)nanocavity-type electrochromic devices with multicolor tunability have attracted significant interest in the past two years for their potential uses in a wide variety of applications,such as electronic display,military camouflage,and dynamic decoration.However,challenges such as insufficient brightness,lengthy switching times,and poor cycling stability have yet to be overcome.Herein,we demonstrate electrochromic electrodes based on ITO/Cu as both the current collector and the reflective layer,with WO_(3 )as the electrochromic material,forming a unique three-layered structure.The constituted WO_(3 )/ITO/Cu films present a high brightness value of about 84%before coloration,and a decent brightness value of 48%after coloration at−0.8V.Moreover,a fast switching time between different coloration states(tc=2.2s;tb=1s)is recorded,attributed to the extremely low sheet resistivity of the ITO/Cu current collector.The films also reveal excellent electrochemical cycling stability across 2000 cycles. | Xueqing Tang Zishou Hu Zhen Wang Jian Chen Xinyang Mu Ge Song Peiyan Sun Zhengji Wen Jiaming Hao Shan Cong Zhigang Zhao | 2022 | eScience2022，2，6： | 1 |
| 4 | Sub-nanometer ultrathin epitaxy of AlGaN and its application in efficient doping显示文摘Solving the doping asymmetry issue in wide gap semiconductors is a key dificulty and long-standing challenge for device applications.Here,a desorption-tailoring strategy is proposed to juggle the carrier concentration and transport.Specific to the p-doping issue in Al-rich AlGaN,self-assembled p-AlGaN superlattices with an average Al composition of over 50%are prepared by adopting this approach.The hole concentration as high as 8.1×10^(18)cm^(-3)is thus realized at room temperature,which is attributed to the signifcant reduction of effective Mg activation energy to 17.5 meV through modulating the activating path,as well as the highlighted Mg surface-incorporation by an intentional interruption for desorption.More importantly,benefting from the constant ultrathin barrier thickness of only three monolayers via this approach,vertical miniband transport of holes is verifed in the p-AlGaN superlattices,greatly satisfying the demand of hole injection in device application.280 nm deep-ultraviolet light emitting diodes are then fabricated as a demo with the desorption-tailored Al-rich p-AlGaN superlattices,which exhibit a great improvement of the carrier injection efficiency and light extraction efficiency,thus leading to a 55.7%increase of the light output power.This study provides a solution for p-type doping of Al-rich AlGaN,and also sheds light on solving the doping asymmetry issue in general for wide-gap semiconductors. | Jiaming Wang Mingxing Wang Fujun Xu Baiyin Liu Jing Lang Na Zhang Xiangning Kang Zhixin Qin Xuelin Yang Xinqiang Wang Weikun Ge Bo Shen | 2022 | Light(Science & Applications)2022，11，4： | 1 |
| 5 | Recent progress and future perspectives of flexible metal‐air batteries显示文摘With the rapid development of wearable and intelligent flexible electronic devices(FEDs),the demand for flexible energy storage/conversion devices(ESCDs)has also increased.Rechargeable flexible metal‐air batteries(MABs)are expected to be one of the most ideal ESCDs due to their high theoretical energy density,cost advantage,and strong deformation adaptability.With the improvement of the device design,material assemblies,and manufacturing technology,the research on the electrochemical performance of flexible MABs has made significant progress.However,achieving the high mechanical flexibility,high safety,and wearable comfortability required by FEDs while maintaining the high performance of flexible MABs are still a daunting challenge.In this review,flexible Zn‐air and Li‐air batteries are mainly exemplified to describe the most recent progress and challenges of flexible MABs.We start with an overview of the structure and configuration of the flexible MABs and discuss their impact on battery performance and function.Then it focuses on the research progress of flexible metal anodes,gel polymer electrolytes,and air cathodes.Finally,the main challenges and future research perspectives involving flexible MABs for FEDs are proposed. | Tingzhen Li Xinwen Peng Peng Cui Ge Shi Wu Yang Zehong Chen Yongfa Huang Yongkang Chen Jinyuan Peng Ren Zou Xiaoyan Zeng Jian Yu Jianyun Gan Zhiyuan Mu Yuling Chen Jiaming Zeng Juan Liu Yunyi Yang Yujia Wei Jun Lu | 2021 | SmartMat2021，2，4： | 1 |
| 6 | Recombinant chimpanzee adenovirus vector vaccine expressing the spike protein provides effective and lasting protection against SARS-CoV-2 infection in mice显示文摘SARS-CoV-2 infection is a global public health threat.Vaccines are considered amongst the most important tools to control the SARS-CoV-2 pandemic.As expected,deaths from SARS-CoV-2 infection have dropped dramatically with widespread vaccination.However,there are concerns over the duration of vaccine-induced protection,as well as their effectiveness against emerging variants of concern.Here,we constructed a recombinant chimpanzee adenovirus vectored vaccine expressing the full-length spike of SARS-CoV-2(Ad C68-S).Rapid and high levels of humoral and cellular immune responses were observed after immunization of C57BL/6J mice with one or two doses of Ad C68-S.Notably,neutralizing antibodies were observed up to at least six months after vaccination,without substantial decline.Single or double doses Ad C68-S immunization resulted in lower viral loads in lungs of mice against SARS-CoV-2 challenge both in the short term(21 days)and long-term(6 months).Histopathological examination of Ad C68-S immunized mice lungs showed mild histological abnormalities after SARS-CoV-2 infection.Taken together,this study demonstrates the efficacy and durability of the Ad C68-S vaccine and constitutes a promising candidate for clinical evaluation. | Mingqing Lu Kunpeng Liu Yun Peng Zhe Ding Yingwen Li Alexander Tendu Xue Hu Ge Gao Weiwei Guo Hang Liu Juhong Rao Jiaxuan Zhao Miaoyu Chen Zhiming Yuan Gary Wong Chao Shan Yanfeng Yao Jiaming Lan | 2022 | Virologica Sinica2022，37，4： | 0 |
| 7 | Progress in efficient doping of Al-rich AlGaN显示文摘The development of semiconductors is always accompanied by the progress in controllable doping techniques.Taking AlGaN-based ultraviolet(UV)emitters as an example,despite a peak wall-plug efficiency of 15.3%at the wavelength of 275 nm,there is still a huge gap in comparison with GaN-based visible light-emitting diodes(LEDs),mainly attributed to the inefficient doping of AlGaN with increase of the Al composition.First,p-doping of Al-rich AlGaN is a long-standing challenge and the low hole concentration seriously restricts the carrier injection efficiency.Although p-GaN cladding layers are widely adopted as a compromise,the high injection barrier of holes as well as the inevitable loss of light extraction cannot be neglected.While in terms of n-doping the main issue is the degradation of the electrical property when the Al composition exceeds 80%,resulting in a low electrical efficiency in sub-250 nm UV-LEDs.This review summarizes the recent advances and outlines the major challenges in the efficient doping of Al-rich AlGaN,meanwhile the corresponding approaches pursued to overcome the doping issues are discussed in detail. | Jiaming Wang Fujun Xu Lisheng Zhang Jing Lang Xuzhou Fang Ziyao Zhang Xueqi Guo Chen Ji Chengzhi Ji Fuyun Tan Xuelin Yang Xiangning Kang Zhixin Qin Ning Tang Xinqiang Wang Weikun Ge Bo Shen | 2024 | Journal of Semiconductors2024，45，2： | 0 |
| 8 | R3-MYB proteins OsTCL1 and OsTCL2 modulate seed germination via dual pathways in rice显示文摘Salt and drought stress are common abiotic factors that exert a detrimental influence on seed germination,potentially leading to significantly impaired growth and production in rice.Gaining a comprehensive understanding of the molecular response of seeds to abiotic stress during the germination is of paramount importance.In the present study,we identified two R3-MYB genes in rice,namely OsTCL1 and OsTCL2,and characterized their roles in regulating seed germination under salt and drought stress.Plants with tcl1 and tcl2 mutant alleles exhibited delayed seed germination,particularly under stress conditions.The tcl1 tcl2 double mutant showed an even more pronounced reduction in germination during initial stages of germination,thereby indicating a redundant regulatory function of OsTCL1 and OsTCL2 in seed germination under abiotic stresses.Furthermore,we demonstrated that the transcript levels of several phospholipase D(PLD)genes were downregulated in the tcl1 tcl2 mutant,resulting in a decreased level of the phosphatidic acid(PA)product.Application of 1-butanol,a competitive substrate inhibitor of PLD-dependent production of PA,attenuated the stress response of the tcl1 tcl2 mutant.This suggests that OsTCL1 and OsTCL2 partially modulate seed germination through the PLD-PA signaling pathway.Moreover,there were alterations in the expression of genes involved in abscisic acid(ABA)biosynthesis,metabolism and signaling transduction in the double mutant.These changes affected the endogenous ABA level and ABA response,thereby influencing seed germination.Application of both 1-butanol and ABA synthesis inhibitor sodium tungstate(Na2WO4)nearly eliminated the differences in stress response between wild type and the tcl1 tcl2 mutant.This indicates that OsTCL1 and OsTCL2 synergistically coordinate seed germination under abiotic stresses through both the PLD-PA signaling and ABA-mediated pathways. | Yong Yi Chan Lin Xueyan Peng Meishan Zhang Jiaming Wu Chunmei Meng Shengchao Ge Yunfeng Liu Yuan Su | 2023 | The Crop Journal2023，11，6： | 0 |
| 9 | Efficient ternary organic solar cells based on a twin spiro-type non-fullerene acceptor显示文摘A novel small-molecule(SM) acceptor DTF-IC is designed and synthesized in this work. The power conversion efficiency(PCE) of ternary OSCs increased up to 12.14% from 10.90% by incorporating 10 wt% of DTF-IC as second acceptors into the binary OSCs consisting of PBDB-T as donor and IT-M as acceptor. This was mainly due to the large increase in short-circuit current(Jsc) from 16.18 to 17.95 mA/cm^2, without any drop in the open-circuit voltage(Voc) and fill factor(FF). The addition of DTF-IC enabled the donor and acceptor to form a distinct complementary absorption profile in the visible-light region, which boosted the photon harvesting in the range of 730–800 nm and consequently increased the Jscof the ternary system by 11%. Moreover, there was an energy transfer between the two SM acceptors, favorable for enhancing charge separation and transfer as well as reducing charge recombination at PBDB-T:IT-M and PBDB-T:DTF-IC interface. Simultaneously, HOMO and LUMO energy levels of DTF-IC were lower than those of PBDB-T, but still higher than those of IT-M. Thus, DTF-IC is able to provide a cascading energy level with the host donor and acceptor which are beneficial for efficient charge transfer between the acceptors and facilitating exciton dissociation and carrier transport. Meanwhile, the highly crystalline DTF-IC as a third component can improve the crystallization process of the active layer while maintaining proper phase separation. This work proposes a novel idea for non-fullerene acceptors achieved via twin spiro-type structure modifying by indanone and provides a new direction for the selection of ternary solar cell materials. | Lirong Wu Lingchao Xie Hanmin Tian Ruixiang Peng Jiaming Huang Billy Fanady Wei Song Songting Tan Wengang Bi Ziyi Ge | 2019 | Science Bulletin2019，64，15： | 0 |
