2Efficient Carbon-Based CsPbBr_3 Inorganic Perovskite Solar Cells by Using Cu-Phthalocyanine as Hole Transport Material显示文摘Metal halide perovskite solar cells(PSCs) have attracted extensive research interest for next-generation solution-processed photovoltaic devices because of their high solar-to-electric power conversion efficiency(PCE)and low fabrication cost. Although the world's best PSC successfully achieves a considerable PCE of over 20% within a very limited timeframe after intensive efforts, the stability, high cost, and up-scaling of PSCs still remain issues. Recently, inorganic perovskite material, CsPbBr_3, is emerging as a promising photo-sensitizer with excellent durability and thermal stability, but the efficiency is still embarrassing. In this work, we intend to address these issues by exploiting CsPbBr_3 as light absorber, accompanied by using Cu-phthalocyanine(CuPc) as hole transport material(HTM) and carbon as counter electrode. The optimal device acquires a decent PCE of 6.21%, over 60% higher than those of the HTM-free devices. The systematic characterization and analysis reveal a more effective charge transfer process and a suppressed charge recombination in PSCs after introducing CuPc as hole transfer layer. More importantly, our devices exhibit an outstanding durability and a promising thermal stability, making it rather meaningful in future fabrication and application of PSCs.Zhiyong Liu Bo Sun Xingyue Liu Jinghui Han Haibo Ye Tielin Shi Zirong Tang Guanglan Liao 2018Nano-Micro Letters2018,10,2:5

4Surface modification with ionic liquid for efficient CsPbI2Br perovskite solar cells显示文摘The presence of numerous trap states on the perovskite surface severely affects the performance of inorganic CsPbI_(2)Br perovskite solar cells.Surface modification has been proven to be an effective strategy to passivate the surface trap states of CsPbI_(2)Br perovskite.However,most modifiers behave high volatility and insulation,not enough to further develop the CsPbI_(2)Br solar cells.Herein,an ionic liquid of 1-viny-3-propionate ethyl imidazolium chloride([PEVIM]Cl)is applied to modify the CsPbI_(2)Br film surface,yielding a compact film with enhanced crystallinity.The surface trap states of CsPbI_(2)Br film are effectively passivated via the interaction between carbonyl group of[PEVIM]Cl and uncoordinated metal cations of CsPbI_(2)Br perovskite,leading to charge recombination suppression and charge transport enhancement.Consequently,the power conversion efficiency(PCE)of[PEVIM]Cl modified CsPbI_(2)Br device is obviously enhanced from 12.49% to 14.19% with an improved open-circuit voltage of 1.160 V.Moreover,the non-encapsulated device presents excellent thermal stability,still maintaining 91%PCE when heated at 85℃ in nitrogen atmosphere for 360 h.Meanwhile,the non-encapsulated device degrades only 11% PCE after stored at 50% relative humidity for 960 h.This simple and efficient approach provides a promising direction to fabricate high-efficiency and stable inorganic perovskite devices.Xingyu Pu Jian Han Shuangjie Wang Hui Zhou Qi Cao Jiabao Yang Ziwei He Xuanhua Li 2021Journal of Materiomics2021,7,5:3
5Photosynthesis and metabolite responses of Isatis indigotica Fortune to elevated [CO2]显示文摘Climate change is affecting global crop productivity, food quality, and security. However,few studies have addressed the mechanism by which elevated CO_2 may affect the growth of medicinal plants. Isatis indigotica Fortune is a widely used Chinese medicinal herb with multiple pharmacological properties. To investigate the physiological mechanism of I.indigotica response to elevated [CO_2], plants were grown at either ambient [CO_2](385 μmol mol^(-1)) or elevated [CO_2] (590 μmol mol^(-1)) in an open-top chamber (OTC)experimental facility in North China. A significant reduction in transpiration rate (T_r) and stomatal conductance (g_s) and a large increase in water-use efficiency contributed to an increase in net photosynthetic rate (Pn) under elevated [CO_2] 76 days after sowing. Leaf non-photochemical quenching (NPQ) was decreased, so that more energy was used in effective quantum yield of PSII photochemistry (Φ_(PSⅡ)) under elevated [CO_2]. High ΦPSII,meaning high electron transfer efficiency, also increased Pn. The [CO_2]-induced increase in photosynthesis significantly increased biomass by 36.8%. Amounts of metabolic compounds involved in sucrose metabolism, pyrimidine metabolism, flavonoid biosynthesis, and other processes in leaves were reduced under elevated [CO_2]. These results showed that the fertilization effect of elevated [CO_2] is conducive to increasing dry weight but not secondary metabolism in I. indigotica.Ping Li Hongying Li Yuzheng Zong Frank Yonghong Li Yuanhuai Han Xingyu Hao 2017The Crop Journal2017,5,4:2
6Experimental Study on the Distribution of Velocity and Pressure near a Submarine Pipeline显示文摘As a transport means of oil and gas the submarine pipeline has many merits, such as continuous delivery, large conveying capacity, convenient management, etc. A tube was chosen in our study to simulate the submarine pipeline in the experiments. A high accuracy instrument ADV and high precision point-type pressure sensors were used to measure the parameters of the flow field, including the pressure distribution, velocities at seven cross sections near the submarine pipeline with five different clearance ratios, and twelve dynamic pressure values around the pipeline. The pressure distributions and velocity changes around the pipe under dif- ferent flow velocities and clearance ratios were analyzed. These results might be useful for further study of submarine pipeline ero- sion and protection.HAN Yan SHI Bing REN Xingyue JING Xiaodong 2009Journal of Ocean University of China2009,8,4:2

8Co_(2)N Nanoparticles Anchored on N-Doped Active Carbon as Catalyst for Oxygen Reduction Reaction in Zinc–Air Battery显示文摘The development of efficient catalytic electrode toward oxygen reduction reaction(ORR)is still a great challenge for the wide use of zinc–air batteries.Herein,Co_(2)N nanoparticles(NPs)anchored on N-doped carbon from cattail were verified with excellent catalytic performances for ORR.The onset and half-wave potentials over the optimal catalyst reach to 0.96 V and 0.84 V,respectively.Current retention rates of 96.8%after 22-h test and 98.8%after running 1600 s were obtained in 1 M methanol solution.Density functional theory simulation proposes an apparently increased electronic states of Co_(2)N in N-doped carbon layer close to the Fermi level.Higher charge density,favorable adsorption,and charge transfer of intermediates originate from the coexistence of Co_(2)N NPs and N atoms in carbon skeleton.The superior catalytic activity of composites also was confirmed in zinc–air batteries.This novel catalytic property and controllable preparation approach of Co_(2)Ncarbon composites provide a promising avenue to fabricate metal-containing catalytically active carbon from biomass.Xianli Wu Guosheng Han Hao Wen Yanyan Liu Lei Han Xingyu Cui Jiajing Kou Baojun Li Jianchun Jiang 2022Energy & Environmental Materials2022,5,3:1
9Tailoring the mercaptan ligands for high performance inverted perovskite solar cells with efficiency exceeding 21%显示文摘Interface passivation engineering has been recognized as an effective way to simultaneously contribute to the optoelectronic characteristic and stability of perovskite solar cells(PSCs). Herein, a p-conjugated dual-ligand 1,4-phenylmercaptan(PHMT) is explored to rationally tailor the surface of perovskite film.The experimental and theoretical results show that the PHMT presents planar structure and obvious electron delocalization characteristics, which allow it to anchor on the surface of perovskite with a certain orientation, thereby promoting the transport of interface charge. Moreover, the two sulfhydryl groups in PHMT reduce the trap density of the perovskite film by passivating under-coordinated lead ions.Consequently, the PHMT-modified inverted device based on MAPbI_(3)(MA: methylammonium) achieves enhanced efficiency from 18.11%(control) to 21.11%, along with the ambient stability up to 3500 h.After being placed at 85 °C for 500 h or illuminated for 600 h, the modified device remains over 89%or 86% of initial efficiency. This discovery opens a new window for the choice of passivators to improve the performance of PSCs.Shuangjie Wang Ziwei He Jiabao Yang Tongtong Li Xingyu Pu Jian Han Qi Cao Bingyu Gao Xuanhua Li 2021Journal of Energy Chemistry2021,30,9:1

12^(235)U enrichment detection system for nuclear fuel rod based on compact D–D neutron generator显示文摘A reliable ^(235)U enrichment uniformity detection system based on a compact D–D neutron generator is developed to detect the ^(235)U enrichment uniformity of different fuel elements in the same nuclear fuel rod. The high-yield compact D–D neutron generator provides 2.45 MeV D–D neutrons, decelerated by a moderator to thermal neutrons or epithermal neutrons, thereby inducing ^(235)U fission to produce highly excited state fission fragments that undergo de-excitation via γ-ray emission. The system detects the ^(235)U enrichment uniformity of a nuclear fuel rod by measuring γ-rays and establishing a relationship between the γ-ray count rate and ^(235)U enrichment in nuclear fuel. The proposed system yields a confidence probability of 99.99% for a relative ^(235)U enrichment deviation of 10% and a neutron yield of 5 × 10^(8) n/s, and the detection accuracy increases with increasing neutron yield. Furthermore, the developed system can satisfy quality control requirements for nuclear fuel production to promote the safe development of nuclear power.WU Kang LIU XingYu YANG Xu LIU ChangQi HUO DongYing BAI XiaoHou HAN Chao JIANG QiaoYue ZHANG Hang PENG JinQiu ZHANG Yu WANG JunRun YAO ZeEn WEI Zheng 2021Science China(Technological Sciences)2021,64,9:1
13USP21 deubiquitylates Nanog to regulate protein stability and stem cell pluripotency显示文摘The homeobox transcription factor Nanog has a vital role in maintaining pluripotency and self-renewal of embryonic stem cells(ESCs).Stabilization of Nanog proteins is essential for ESCs.The ubiquitin–proteasome pathway mediated by E3 ubiquitin ligases and deubiquitylases is one of the key ways to regulate protein levels and functions.Although ubiquitylation of Nanog catalyzed by the ligase FBXW8 has been demonstrated,the deubiquitylase that maintains the protein levels of Nanog in ESCs yet to be defined.In this study,we identify the ubiquitin-specific peptidase 21(USP21)as a deubiquitylase for Nanog,but not for Oct4 or Sox2.USP21 interacts with Nanog protein in ESCs in vivo and in vitro.The C-terminal USP domain of USP21 and the C-domain of Nanog are responsible for this interaction.USP21 deubiquitylates the K48-type linkage of the ubiquitin chain of Nanog,stabilizing Nanog.USP21-mediated Nanog stabilization is enhanced in mouse ESCs and this stabilization is required to maintain the pluripotential state of the ESCs.Depletion of USP21 in mouse ESCs leads to Nanog degradation and ESC differentiation.Overall,our results demonstrate that USP21 maintains the stemness of mouse ESCs through deubiquitylating and stabilizing Nanog.Xingyu Liu Yuying Yao Huiguo Ding Chuanchun Han Yuhan Chen Yuan Zhang Chanjuan Wang Xin Zhang Yiling Zhang Yun Zhai Ping Wang Wenyi Wei Jing Zhang Lingqiang Zhang 2016Signal Transduction and Targeted Therapy2016,1,1:1
14A common variant in AAK1 reduces risk of noise-induced hearing loss显示文摘Noise-induced hearing loss(NIHL)is one of the most common types of hearing loss and contributes to significant morbidity worldwide,as well as being the major cause of age-related hearing loss and tinnitus.The World Health Organization(WHO)estimates that 10%of the world's population is exposed to sound levels that could potentially cause NIHL[1].It has been widely accepted that NIHL is a multifactorial genetic disorder with estimated heritability of 36%to 40%[2].Ideally,identification of the modifying genetic variants would help protect individuals at high risk of NIHL.For decades,many geneticists have searched for genes that either predispose or protect from NIHL.Howeve r,the majority of genetic studies for NIHL were conducted in independent known candidate genes[3].Qixuan Wang Xueling Wang Tao Yang Lu Yang Huihui Liu Yihang Zheng Guixian Jiang Hongchao Liu Chenhui Huang Juan Chen Zhentao Wang Zhaoyan Wang Wei Zhao Jiannan Lin Xuejie Zhang Junbo Shi Kun Han Xingyu Le Yan Ren Yun Li Yingying Hong Wentao Shi Dongqi Cui Minfei Qian Jun Xu Xiaofei Zheng Yunge Gao Chen Li James Lin Zhiwu Huang Hao Wu 2023National Science Review2023,10,7:0
15Multidentate anchoring through additive engineering for highly efficient Sb_(2)S_(3)planar thin film solar cells显示文摘Sb_(2)S_(3)is a promising candidate for the flexible solar cells or the top subcells in tandem solar cells due to its wide-bandgap,less toxic,acceptable cost and progressive power conversion efficiency(PCE).However,the poor quality and high trap states of Sb_(2)S_(3)films limit the device performance further enhancement.Herein,we adopt a multidentate ionic liquid,tetramethylammonium hexafluorophosphate([TMA][PF_(6)])as a novel additive to address this issue.The octahedral[PF_(6)]~-contains six different oriented fluorine atoms with the lone pair electrons,which could coordinate with Sb atoms due to the multidentate anchoring.Thus,the high-quality Sb_(2)S_(3)film with low trap states has been achieved.Moreover,the Fermi level of the Sb_(2)S_(3)film has been upshifted,thereby showing an effective charge transfer.As a result,all photovoltaic parameters of the optimized Sb_(2)S_(3)devices are obviously enhanced,boosting the final PCE from 4.43(control device)to 6.83%.Our study about the multidentate anchoring is manifested to be an effective method to enhance the Sb_(2)S_(3)device performance.Jian Han Xingyu Pu Hui Zhou Qi Cao Shuangjie Wang Jiabao Yang Junsong Zhao Xuanhua Li 2021Journal of Materials Science & Technology2021,,30:0
16Effective additive for enhancing the performance of Sb_(2)S_(3) planar thin film solar cells显示文摘Sb_(2)S_(3) is a promising photovoltaic absorber with appropriate bandgap,excellent light absorption coefficient and great stability.However,the power conversion efficiency(PCE)of Sb_(2)S_(3) planar thin film solar cells is unsatisfactory for further commercial application due to low crystallinity and high resistivity of Sb_(2)S_(3) film.Here,we introduce an additive of 4-Chloro-3-nitrobenzenesulfonyl Chloride(CSCl)to alleviate these problems.The CSCl molecular contains two terminal Cl with lone pair electrons,which have the interaction with Sb atoms.Thus,the Sb_(2)S_(3) film with enhanced crystallization and low trap states has been obtained and the resistivity is also decreased.Furthermore,CSCl additive raises the Fermi level of the Sb_(2)S_(3) film,thereby enhancing the transport of electron from Sb_(2)S_(3) to TiO_(2).Consequently,the optimal PCE of Sb_(2)S_(3) solar cells is raised from 4.20%(control device)to 5.84%.Our research demonstrates a novel additive to enhance the photoelectric performance of Sb_(2)S_(3) solar cells.Hui Zhou Jian Han Xingyu Pu Xuanhua Li 2021Journal of Materiomics2021,7,5:0
17Exploring the nature of black hole and gravity with an imminent merging binary of supermassive black holes显示文摘A supermassive binary black-hole candidate SDSS J1430+2303 reported recently motivates us to investigate an imminent binary of supermassive black holes as potential gravitational wave source, and the radiated gravitational waves at the end of the merger are shown to be in the band of space-borne detectors. We provide a general analysis on the required detecting sensitivity needed for probing such type gravitational wave sources and make a full discussion by considering two typically designed configurations of space-borne antennas. If a source is so close, it is possible to be detected with Taiji pathfinder-plus which is proposed to be an extension for the planned Taiji pathfinder by just adding an additional satellite to the initial two satellites. The gravitational wave detection on such kind of source enables us to explore the properties of supermassive black holes and the nature of gravity.Xingyu Zhong Wen-Biao Han Ziren Luo Yueliang Wu 2023Science China(Physics,Mechanics & Astronomy)2023,66,3:0
18Eff ects of climate change on the potential habitat distribution of swimming crab Portunus trituberculatus under the species distribution model显示文摘Over the last decades,the species distribution model(SDM)has become an essential tool for studying the potential eff ects of climate change on species distribution.In this study,an ensemble SDM was developed to predict the changes in species distribution of swimming crab Portunus trituberculatus across diff erent seasons in the future(2050s and 2100s)under the climate scenarios of Representative Concentration Pathway(RCP)4.5 and RCP8.5.Results of the ensemble SDM indicate that the distribution of this species will move northward and exhibit evident seasonal variations.Among the four seasons,the suitable habitat for this species will be signifi cantly reduced in summer,with loss rates ranging from 45.23%(RCP4.5)to 88.26%(RCP.8.5)by the 2100s.The loss of habitat will mostly occur in the East China Sea and the southern part of the Yellow Sea,while a slight increase in habitat will occur in the northern part of the Bohai Sea.These fi ndings provide an information forecast for this species in the future.Such forecast will be helpful in improving fi shery management under climate change.Xingyu LIU Xiaolu HAN Zhiqiang HAN 2022Journal of Oceanology and Limnology2022,40,4:0
19Chitosan oligosaccharide addition modifies nutrient utilization in highly-valued ornamental tree seedlings显示文摘Forestation in the increasingly urbanized area generates a huge demand for ornamental tree stocks, requiring new approach to promote the cultural efficiency of highly valued seedlings. Chitosan oligosaccharide(COS) is one of biodegradable natural plant growth modifier derived from chitin and an abundant water insoluble biopolymer. In this study, Buddhist pine(Podocarpus macrophyllus)(PM) and Northeast yew(Taxus cuspidata)(TC) were cultured with or without COS addition from 1 July to 17 November 2016. Relative to the TC seedlings, the PM seedlings had greater growth of height and biomass which was found to be negatively correlated with the changes of nitrogen(N) and phosphorus(P) concentrations in shoot during the culture. Only those TC seedlings treated without COS addition had higher proportion of decline in the initial N concentration than that in the PM seedlings. Root P concentration declined less in Buddhist pine seedlings than that in Northeast yew seedlings treated with COS. By 17 of November 2016, both N and P seemed to have been diluted in the PM seedlings and exceed the demand in the TC seedlings. In conclusion, COS had the potential to be used for the culture of ornamental tree seedlings to promote nutrient utilization for shoot biomass accumulation, but more specific effect on nutrient allocation and utilization need to be confirmed by more studies.Wang Yanjie Wei Hongxu Ge Lili Sun Naiwei Wang Ting Zhang Qichang Han Lianbin Ge Xingyu Jin Guangyu 2018林业与环境科学2018,34,3:0
20SD-RLK28 positively regulates pollen hydration on stigmas as a PCP-Bβ receptor in Arabidopsis thaliana显示文摘Pollen hydration on dry stigmas is strictly regulated by pollen–stigma interactions in Brassicaceae. Although several related molecular events have been described, the molecular mechanism underlying pollen hydration remains elusive. Multiple B-class pollen coat proteins(PCP-Bs) are involved in pollen hydration. Here, by analyzing the interactions of two PCP-Bs with three Arabidopsis thaliana stigmas strongly expressing S-domain receptor kinase(SD-RLK), we determined that SD-RLK28 directly interacts with PCP-Bβ. We investigated pollen hydration, pollen germination, pollen tube growth, and stigma receptivity in the sd-rlk28 and pcp-bβ mutants. PCP-Bβ acts in the pollen to regulate pollen hydration on stigmas. Loss of SD-RLK28 had no effect on pollen viability, and sd-rlk28 plants had normal life cycles without obvious defects. However,pollen hydration on sd-rlk28 stigmas was impaired and pollen tube growth in sd-rlk28 pistils was delayed. The defect in pollen hydration on sd-rlk28 stigmas was independent of changes in reactive oxygen species levels in stigmas. These results indicate that SD-RLK28 functions in the stigma as a PCP-Bβ receptor to positively regulate pollen hydration on dry stigmas.Li Guo Ziya Huang Xingyu Chen Min Yang Miaomiao Yang Ziwei Liu Xuejie Han Xiangjie Ma Xiaoli Wang Qiguo Gao 2023Journal of Integrative Plant Biology2023,65,10:0
