| 1 | Quantitative estimation of climate change effects on potential evapotranspiration in Beijing during 1951-2010显示文摘Climate change is likely to affect hydrological cycle through precipitation,evapotranspiration,soil moisture etc.In the present study,an attempt has been made to study the climate change and the sensitivity of estimated evapotranspiration to each climatic variable for a semi-arid region of Beijing in North China using data set from 1951 to 2010.Penman-Monteith method was used to calculate reference crop evapotranspiration(ETo).Changes of ETo to each climatic variable was estimated using a sensitivity analysis method proposed in this study.Results show that in the past 60 years,mean temperature and vapor pressure deficit(VPD) were significantly increasing,relative humidity and sunshine hours were significantly decreasing,and wind speed greatly oscillated without a significant trend.Total precipitation was significantly decreasing in corn season(from June to September),but it was increasing in wheat season(from October to next May).The change rates of temperature,relative humidity,VPD,wind speed,annual total precipitation,sunshine hours and solar radiation were 0.42℃,1.47%,0.04 kPa,0.05 m·s–1,25.0 mm,74.0 hours and 90.7 MJ·m–2per decade,respectively.In the past 60 years,yearly ETo was increasing with a rate of 19.5 mm per decade,and total ETos in wheat and corn seasons were increasing with rates of 13.1 and 5.3 mm per decade,respectively.Sensitivity analysis showed that mean air temperature was the first key factor for ETo change in the past 60 years,causing an annual total ETo increase of 7.4%,followed by relative humidity(5.5%) and sunshine hours(–3.1%);the less sensitivity factors were wind speed(0.7%),minimum temperature(–0.3%) and maximum temperature(–0.2%).A greater reduction of total ETo(12.3%) in the past 60 years was found in wheat season,mainly because of mean temperature(8.6%) and relative humidity(5.4%),as compared to a reduction of 6.0% in ETo during corn season due to sunshine hours(–6.9%),relative humidity(4.7%) and temperature(4.5%).Increasing precipitation in the wheat season will improve crop growth,while decreasing precipitation and increasing ETo in the corn season induces a great pressure for local government and farmers to use water more efficiently by widely adopting water-saving technologies in the future. | LIU Haijun LI Yan JOSEF Tanny ZHANG Ruihao HUANG Guanhua | 2014 | Journal of Geographical Sciences2014，24，1： | 10 |
| 2 | Indocyanine Green-Conjugated Magnetic Prussian Blue Nanoparticles for Synchronous Photothermal/Photodynamic Tumor Therapy显示文摘Indocyanine green(ICG) is capable of inducing a photothermal effect and the production of cytotoxic reactive oxygen species for cancer therapy. However, the major challenge in applying ICG molecules for antitumor therapy is associated with their instability in aqueous conditions and rapid clearance from blood circulation,which causes insufficient bioavailability at the tumor site.Herein, we conjugated ICG molecules with Prussian blue nanoparticles enclosing a Fe_3O_4 nanocore, which was facilitated by cationic polyethyleneimine via electrostatic adsorption. The nanocarrier-loaded ICG formed stable aggregates that enhanced cellular uptake and prevented fluorescence quenching. Moreover, the strong superparamagnetism of the Fe_3O_4 core in the obtained nanocomposites further improved cellular internalization of the drugs guided by a localized magnetic field. The therapeutic efficacy of this nanoplatform was evaluated using tumor models established in nude mice, which demonstrated remarkable tumor ablation in vivo due to strong photothermal/photodynamic effects. This study provides promising evidence that this multifunctional nanoagent might function as an efficient mediator for combining photothermal and photodynamic cancer therapy. | Peng Xue Ruihao Yang Lihong Sun Qian Li Lei Zhang Zhigang Xu Yuejun Kang | 2018 | Nano-Micro Letters2018，10，4： | 3 |
| 3 | 8.0% Efficient all-polymer solar cells based on novel starburst polymer acceptors显示文摘The polymer N2200, with its π-conjugated backbone composed of alternating naphthalene diimide(NDI) and bithiophene(DT)units, has been widely used as an acceptor for all-polymer solar cells(all-PSCs) owing to its high electron mobility and suitable ionization potential and electron affinity. Here, we developed two naphthalene diimide derivatives by modifying the molecular geometry of N2200 through the incorporation of a truxene unit as the core and NDI-DTas the branches. These starburst polymers exhibited absorption spectra and molecular orbital energy levels that were comparable to N2200. These copolymers were paired with the wide-bandgap polymer donor PTz BI-O to fabricate all-polymer solar cells(all-PSCs), which displayed impressive power conversion efficiencies up to 8.00%. The improved photovoltaic performances of all-PSCs based on these newly developed starburst acceptors can be ascribed to the combination of increased charge carrier mobilities, reduced bimolecular recombination, and formation of more favorable film morphology. These findings demonstrate that the construction of starburst polymer acceptors is a feasible strategy for the fabrication of high-performance all-PSCs. | Kang Li Ruihao Xie Wenkai Zhong Kaiwen Lin Lei Ying Fei Huang Yong Cao | 2018 | Science China Chemistry2018，61，5： | 2 |
| 4 | Homogeneous-like Alkyne Selective Hydrogenation Catalyzed by Cationic Nickel Confined in Zeolite显示文摘The selective hydrogenation of alkynes to their corresponding alkenes is an important type of organic transformation,which is currently accomplished by modified palladium catalysts.Herein,we report that coordinatively unsaturated Ni(II)sites confined in faujasite zeolite,that is,Ni@Y,can efficiently catalyze the selective hydrogenation of various alkynes in both gas-and liquid phase.Spectroscopic and kinetic analyses explicitly reveal that alkyne hydrogenation over Ni@Y follows the homogeneous associative mechanism instead of the classic heterogeneous Horiuti–Polanyi mechanism.Density functional theory calculations confirm that the preferential adsorption of alkynes on coordinatively unsaturated Ni(II)sites is crucial to initiate dihydrogen activation for the subsequent hydrogenation.Ni@Y represents a true heterogeneous catalyst acting as a homogeneous catalyst and shares the advantages of both heterogeneous and homogeneous catalysis.These findings may shed light on the rational design of robust catalysts and new catalytic routes by linking heterogeneous and homogeneous catalysis. | Xin Deng Ruihao Bai Yuchao Chai Zhenpeng Hu Naijia Guan Landong Li | 2022 | CCS Chemistry2022，4，3： | 1 |
| 5 | Scalable spray coated high performance sulfurized electron transporter for efficient and stable perovskite solar modules显示文摘The stability issue has been acknowledged as the bottleneck in the practical application of perovskite photovoltaics,while the stabilized interface between the perovskites and charge transport layers dominates their stability performance under different stresses.Here,we developed a high-performance sulfurized zinc-titanium mixed oxide(ZTO-S)electron transport layer(ETL)to fabricate large-area efficient and long-term 85℃/85%RH stable perovskite solar modules.The scalably prepared ZTO-S using the facile spray coating method demonstrates excellent electron mobility close to that of Zn O,in addition to promoting the uniform crystallization of perovskite film across the entire module via the interaction between surface S and Pb^(2+).Furthermore,this novel coordination stabilized the interface and reduced the interfacial non-radiative recombination defects within the devices,yielding an efficient and stable performance for the modules.High efficiency of 21.73%and 17.50%was achieved for blade-coated 36 cm^(2)and 100 cm^(2)perovskite solar modules,respectively.In addition,the encapsulated module(36 cm^(2))shows an attractive humidity and heat stability(85℃/85%RH)performance with a maintained 93.5%of the initial PCE over 1000 h. | Siqing Nie Qifan Feng Ziheng Tang Yaolin Hou Xiaofeng Huang Ruihao Chen Fang Cao Binghui Wu Jun Yin Jing Li Nanfeng Zheng | 2022 | Journal of Energy Chemistry2022，，12： | 1 |
| 6 | Investigation of electronic excited states in single-molecule junctions显示文摘The investigation of electronic excited states in single-molecule junctions not only provides platforms to reveal the photophysical and photochemical processes at the molecular level,but also brings opportunities for the development of single-molecule optoelectronic devices.Understanding the interaction mechanisms between molecules and nanocavities is essential to obtain ondemand properties in devices by artificial design,since molecules in junctions exhibit unique behaviors of excited states benefited from the structures of metallic nanocavities.Here,we review the excitation mechanisms involved in the interplay between molecules and plasmonic nanocavities,and reveal the influence of nanostructures on excited-state properties by demonstrating the differences in excited state decay processes.Furthermore,vibronic transitions of molecules between nanoelectrodes are also discussed,offering a new single-molecule characterization method.Finally,we provide the potential applications and challenges in single-molecule optoelectronic devices and the possible directions in exploring the underlying mechanisms of photophysical and photochemical processes. | Wei Xu Ruihao Li Chenhao Wang Jiahe Zhong Junyang Liu Wenjing Hong | 2022 | Nano Research2022，15，6： | 1 |

| 8 | Microbial and metabolomic mechanisms mediating the effects of dietary inulin and cellulose supplementation on porcine oocyte and uterine development显示文摘Background:Dietary fiber(DF)is often eschewed in swine diet due to its anti-nutritional effects,but DF is attracting growing attention for its reproductive benefits.The objective of this study was to investigate the effects of DF intake level on oocyte maturation and uterine development,to determine the optimal DF intake for gilts,and gain microbial and metabolomic insight into the underlying mechanisms involved.Methods:Seventy-six Landrace×Yorkshire(LY)crossbred replacement gilts of similar age(92.6±0.6 d;mean±standard deviation[SD])and body weight(BW,33.8±3.9 kg;mean±SD)were randomly allocated to 4 dietary treatment groups(n=19);a basal diet without extra DF intake(DF 1.0),and 3 dietary groups ingesting an extra50%(DF 1.5),75%(DF 1.75),and 100%(DF 2.0)dietary fiber mixture consisting of inulin and cellulose(1:4).Oocyte maturation and uterine development were assessed on 19 d of the 2nd oestrous cycle.Microbial diversity of faecal samples was analysed by high-throughput pyrosequencing(16S r RNA)and blood samples were subjected to untargeted metabolomics.Results:The rates of oocytes showing first polar bodies after in vitro maturation for 44 h and uterine development increased linearly with increasing DF intake;DF 1.75 gilts had a 19.8%faster oocyte maturation rate and a 48.9 cm longer uterus than DF 1.0 gilts(P<0.05).Among the top 10 microbiota components at the phylum level,8increased linearly with increasing DF level,and the relative abundance of 30 of 53 microbiota components at the genus level(>0.1%)increased linearly or quadratically with increasing DF intake.Untargeted metabolic analysis revealed significant changes in serum metabolites that were closely associated with microbiota,including serotonin,a gut-derived signal that stimulates oocyte maturation.Conclusions:The findings provide evidence of the benefits of increased DF intake by supplementing inulin and cellulose on oocyte maturation and uterine development in gilts,and new microbial and metabolomic insight into the mechanisms mediating the effects of DF on reproductive performance of replacement gilts. | Zhaoyue Men Meng Cao Yuechan Gong Lun Hua Ruihao Zhang Xin Zhu Lianchao Tang Xuemei Jiang Shengyu Xu Jian Li Lianqiang Che Yan Lin Bin Feng Zhengfeng Fang De Wu Yong Zhuo | 2022 | Journal of Animal Science and Biotechnology2022，13，3： | 1 |
| 9 | Enhancing single-molecule conductance of platinum (Ⅱ) complexes through synergistic aromaticity-assisted structural asymmetry显示文摘Seeking the strategies of designing highly conductive molecular structures is one of the core researches in molecular electronics.As asymmetric structure has manifested feasible properties in comprehensive fields, we introduce the structures of asymmetric platinum(Ⅱ) complexes into the charge transport study at single-molecule scale for the first time. The single-molecule conductance measurement results reveal that, in platinum(Ⅱ)-aryloligoynyl structures, the conductance of asymmetrically coordinated complexes is obviously higher than that of the symmetric isomers with the same molecular length, while the conductance is almost identical in symmetric and asymmetric platinum(Ⅱ)-oligoynyl complexes. Theoretical study uncovers that, upon connecting to the oligoynyl structure, the aromatic group effectively extends the π-system of the whole conductive backbone and gathers the HOMO population mainly on the longer oligoynyl ligand, which reduces the energy barrier in electron transport and enhances the conductance through HOMO energy lifting. This result provides feasible strategy for achieving high conductive molecular devices. | Ping Duan Junyang Liu Jin-Yun Wang Kai Qu Shuning Cai Fei Wang Lichuan Chen Xiaoyan Huang Ruihao Li Jia Shi Qian-Chong Zhang Wenjing Hong Zhong-Ning Chen | 2020 | Science China Chemistry2020，63，4： | 0 |
| 10 | Evaluation and modification of potential evapotranspiration methods in Beijing,China显示文摘In this study,seven widely used potential evapotranspiration(ETo)methods were evaluated by comparing with the FAO-56 Penman-Monteith method(PM method)to provide useful information for selecting appropriate ETo equations under data-limited condition in Beijing,China.Statistical methods and parameters,namely linear regression,root mean squared error(RMSE)and mean bias error(MBE),were used to evaluate the seven ETo methods.Results showed that ETo estimated using Kimberly-Penman method have fairly close agreement with the PM method(referring to standard ETo),considering the coefficient of determination(R^(2))of 0.96,RMSE of 0.42 mm/day,and a coefficient of efficiency(E)of 0.96.Locally calibrated Penman and Doorenbos-Pruitt methods also have better agreement with the PM method,correspondingly with R^(2)of 0.99 and 0.95,RMSEs of 0.24 mm/day and 0.21 mm/day,and coefficients of efficiency of 1.02 and 0.99,respectively.The ETo is the most sensitive to vapor pressure deficit(VPD)and net radiation in the Beijing area.Hence,the VPD-based and VPD-radiation combined ETo methods were developed and calibrated.Results showed that the two developed methods performed well in ETo estimation.By fully considering the data-limit situation,the calibrated Turc method,VPD-based method and VPD-radiation-combined method may be attractive alternatives to the more complex Penman−Monteith method in Beijing. | Liu Haijun Li Yan Zhang Ruihao Huang Guanhua | 2013 | International Journal of Agricultural and Biological Engineering2013，6，4： | 0 |
| 11 | Creep anisotropy behavior,deformation mechanism,and its efficient suppression method in Inconel 625 superalloy显示文摘Mill products,such as sheets,usually show obvious anisotropy in their mechanical properties,which greatly affects both their applications and workability.In this study,the orientation-dependent tensile and creep behaviors of Inconel 625 alloy sheets with weak local textures were systematically investigated at 650°C.The results showed that Inconel 625 superalloy exhibits nearly isotropic tensile properties;how-ever,obvious creep anisotropy appears when loading along different directions.Creep life in the rolling direction(150±5 h)was approximately 4.5 times longer than in the transverse direction(33±1 h).Se-vere creep anisotropy was found to be determined by two aspects:(i)the change in deformation mecha-nisms along the rolling direction(a combination of boundary sliding,dislocation slipping,and twinning)and the transverse direction(dislocation slipping).Stronger impingement of slip bands on grain bound-aries accelerated intergranular crack initiation and propagation during loading along the transverse direc-tion,which resulted in a short creep life.(ii)The differences in strain compatibility at grain boundaries(i.e.,creep loading along the transverse direction resulted in the initial grains forming strong Brass,Cu,and S textures).Creep cracks preferentially nucleated at the junctions between Cu/Brass texture grains,as these interfaces exhibit the worst strain compatibility(Luster-Morris parameter m≤0.22).Furthermore,pre-stress aging(PSA)treatment is proposed as an efficient method to suppress creep anisotropy.The discrepancy rate of creep life was found to be reduced by nearly 50%after PSA treatment. | Xudong Liu Jiangkun Fan Kai Cao Fulong Chen Ruihao Yuan Degui Liu Bin Tang Hongchao Kou Jinshan Li | 2023 | Journal of Materials Science & Technology2023，，2： | 0 |

| 13 | Combined molecular docking, homology modeling and DFTmethod for the modification of bovine serum albumin (BSA) toimprove fluorescence spectroscopy for phthalate acid esterschelated with BSA显示文摘While phthalate acid esters(PAEs)cannot fluoresce alone,they can be detected by fluorescence spectroscopy after chelation with bovine serum albumin(BSA).In this study,the types of amino acid residues at the active site of PAEs chelated with BSA were determined using molecular docking technology.A modification scheme of BSA with higher detection sensitivity fluorescence spectroscopy for PAEs was proposed based on the docking results and constructed for a novel BSA structure with a higher detection sensitivity of fluorescence spectroscopy using a homologous modeling method.Density functional theory(DFT)was employed to explore the influence before and after BSA modification on PAEs’detection through fluorescence spectroscopy.The results showed that the docking scores between BSAs and dimethyl phthalate(DMP),dibutyl phthalate(DBP)and di-n-octyl phthalate(DNOP)were increased up to 26.45%,16.82%and 16.30%,respectively,indicating that the active site modification of BSA could enhance the binding affinity between BSA and PAEs.The fluorescence intensity of PAEs chelated with modified BSAs were calculated.The fluorescence intensity of fluorescence spectroscopy for DMP,DBP and DNOP chelated with BSAs after modification was increased up to 2.8-,104.51-and 62.43-fold,respectively,which achieved the purpose of theoretically modifying BSA to improve the detection sensitivity of fluorescence spectroscopy for PAEs. | MINGHAO LI YOULI QIU WENHUI ZHANG RUIHAO SUN MEIJIN DU LUZE YANG YU LI | 2020 | BIOCELL2020，44，2： | 0 |
| 14 | XMe - Xiamen Molecular Electronics Code:An Intelligent and Open-Source Data Analysis Tool for Single-Molecule Conductance Measurements显示文摘Charge transport characterization of single-molecule junctions is essential for the fundamental research of single-molecule physical chemistry and the development towards single-molecule electronic devices and circuits. Among the single-molecule conductance characterization techniques,the single-molecule break junction technique is widely used in tens of worldwide research laboratories which can generate a large amount of experimental data from thousands of individual measurement cycles. However,data interpretation is a challenging task for researchers with different research backgrounds,and the different data analysis approaches sometimes lead to the misunderstanding of the measurement data and even reproducibility issues of the measurement. It is thus a necessity to develop a user-friendly all-in-one data analysis tool that automatizes the basic data analysis in a standard and widely accepted way. In this work,we present the XMe Code (Xiamen Molecular Electronics Code),an intelligent all-in-one data analysis tool for the comprehensive analysis of single-molecule break junction data. XMe code provides end-to-end data analysis that takes in the original experimental data and returns electronic characteristics and even charge transport mechanisms. We believe that XMe Code will promote the transparency of the data analysis in single-molecule electronics and the collaborations among scientists with different research backgrounds. | Zhichao Pan Gang Dong Chi Shang Ruihao Li Tengyang Gao Luchun Lin Huicong Duan Xiaohui Li Jie Bai Yilin Lai Wenfeng Wu Jia Shi Junyang Liu Wenjing Hong | 2024 | Chinese Journal of Chemistry2024，42，3： | 0 |
