| 1 | Retrieval of global terrestrial solar-induced chlorophyll fluorescence from TanSat satellite显示文摘The first Chinese Carbon Dioxide Observation Satellite Mission(TanSat), which was launched on December 21, 2016, is intended to measure atmospheric CO_2 concentration.The high spectral resolution(0.044 nm) and high SNR(360 at 15.2 mW m^(-1) sr^(-1) nm^(-1)) measurements in the region of the O_2-A band of the Atmospheric Carbon dioxide Grating Spectroradiometer(AGCS) module onboard TanSat make it possible to retrieve solar-induced chlorophyll fluorescence(SIF) from TanSat observations at the global scale.This paper aims to explore the potential of the TanSat data for global SIF retrieval.A singular vector decomposition(SVD) statistical method was employed to retrieve SIF using radiance over a micro spectral window(~2 nm) around the Fe Fraunhofer lines(centered at 758.8 nm).The global SIF at 758.8 nm was successfully retrieved with a low residual error of 0.03 mW m^(-1) sr^(-1) nm^(-1).The results show that the spatial and temporal patterns of the retrieved SIF agree well with the global terrestrial vegetation pattern.The monthly SIF products retrieved from the TanSat data were compared with other remote sensing datasets, including OCO-2 SIF, MODIS NDVI, EVI and GPP.The overall consistency between TanSat and OCO-2 SIF products(R^2= 0.86) and the consistency of the spatial patterns and temporal variations between the TanSat SIF and MODIS vegetation indices and GPP enhance our confidence in the potential and feasibility of TanSat data for SIF retrieval.TanSat, therefore, provides a new opportunity for global sampling of SIF at fine spatial resolution(2 km × 2 km), thus improving photosynthesis observations from space. | Shanshan Du Liangyun Liu Xinjie Liu Xiao Zhang Xingying Zhang Yanmeng Bi Lianchong Zhang | 2018 | Science Bulletin2018,63,22: | 29 |
| 2 | Supercritical water oxidation of polyvinyl alcohol and desizing wastewater: Influence of NaOH on the organic decomposition显示文摘Polyvinyl alcohol is a refractory compound widely used in industry. Here we report supercritical water oxidation of polyvinyl alcohol solution and desizing wastewater with and without sodium hydroxide addition. However, it is difficult to implement complete degradation of organics even though polyvinyl alcohol can readily crack under supercritical water treatment. Sodium hydroxide had a significant catalytic effect during the supercritical water oxidation of polyvinyl alcohol. It appears that the OH ion participated in the C-C bond cleavage of polyvinyl alcohol molecules, the CO2-capture reaction and the neutralization of intermediate organic acids, promoting the overall reactions moving in the forward direction. Acetaldehyde was a typical intermediate product during reaction. For supercritical water oxidation of desizing wastewater, a high destruction rate (98.25%) based on total organic carbon was achieved. In addition, cases where initial wastewater was alkaline were favorable for supercritical water oxidation treatment, but salt precipitation and blockage issues arising during the process need to be taken into account seriously. | Jie Zhang Shuzhong Wang Yang Guo Donghai Xu Yanmeng Gong Xingying Tang | 2013 | Journal of Environmental Sciences2013,25,8: | 15 |
| 3 | Responses of Saline Soil Properties and Cotton Growth to Different Organic Amendments显示文摘Application of organic waste to saline alkaline soils is considered to be a good practice for soil remediation. The effects of applying different organic amendments(e.g., cattle dung, vermicompost, biofertilizer) and earthworm inoculations(Eisenia fetida) on saline soils and cotton growth were investigated during 1 year of cotton cultivation. Compared to the control(applied with inorganic NPK fertilizer), applying organic amendments improved soil physicochemical properties. Biofertilizer application improved available nutrient content, reduced short-term soil electrical conductivity, and produced the highest cotton yield, whereas cattle dung and vermicompost applications resulted in higher soil organic matter content. Application of organic amendments significantly increased soil microbial biomass carbon during the flowering period, which sharply declined at harvest. This was especially true for the biofertilizer treatment,which also exhibited lower nematode abundance compared with the other organic materials. Earthworm inoculation following cattle dung application failed to significantly change soil physicochemical properties when compared to the treatments without earthworm inoculation. Results suggest that biofertilizer application to saline soil would improve soil nutrient status in the short-term, whereas cattle dung application would improve soil organic matter content and increase soil organism abundance to a greater extent. However,different strategies might be required for long-term saline soil remediation. | WU Yupeng LI Yufei ZHANG Yi BI Yanmeng SUN Zhenjun | 2018 | Pedosphere2018,28,3: | 13 |
| 4 | All-optical manipulation of micrometer-sized metallic particles显示文摘Optical traps use focused laser beams to generate forces on targeted objects ranging in size from nanometers to micrometers. However, for their high coefficients of scattering and absorption, micrometer-sized metallic particles were deemed non-trappable in three dimensions using a single beam. This barrier is now removed. We demonstrate, both in theory and experiment, three-dimensional(3D) dynamic all-optical manipulations of micrometersized gold particles under high focusing conditions. The force of gravity is found to balance the positive axial optical force exerted on particles in an inverted optical tweezers system to form two trapping positions along the vertical direction. Both theoretical and experimental results confirm that stable 3D manipulations are achievable for these particles regardless of beam polarization and wavelength. The present work opens up new opportunities for a variety of in-depth research requiring metallic particles. | YUQUAN ZHANG XIUJIE Dou YANMENG DAI XIANYOU WANG CHANGJUN MIN AND XIAOCONG YUAN | 2018 | Photonics Research2018,6,2: | 6 |
| 5 | Enhancing plasmonic trapping with a perfect radially polarized beam显示文摘Strong plasmonic focal spots, excited by radially polarized light on a smooth thin metallic film, have been widely applied to trap various micro-and nano-sized objects. However, the direct transmission part of the incident light leads to the scattering force exerted on trapped particles, which seriously affects the stability of the plasmonic trap.Here we employ a novel perfect radially polarized beam to solve this problem. Both theoretical and experimental results verify that such a beam could strongly suppress the directly transmitted light to reduce the piconewton scattering force, and an enhanced plasmonic trapping stiffness that is 2.6 times higher is achieved in experiments.The present work opens up new opportunities for a variety of research requiring the stable manipulations of particles. | xianyou wang yuquan zhang yanmeng dai changjun min xiaocong yuan | 2018 | Photonics Research2018,6,9: | 5 |
| 6 | Embryoid bodies formation and differentiation from mouse embryonic stem cells in collagen/Matrigel scaffolds显示文摘Embryonic stem (ES) cells have the potential to develop into any type of tissue and are considered as a promising source of seeding cells for tissue engineering and transplantation therapy.The main catalyst for ES cells differentiation is the growth into embryoid bodies (EBs),which are utilized widely as the trigger of in vitro differentiation.In this study,a novel method for generating EBs from mouse ES cells through culture in collagen/Matrigel scaffolds was successfully established.When single ES cells were seeded in three dimensional collagen/Matrigel scaffolds,they grew into aggregates gradually and formed simple EBs with circular structures.After 7 days' culture,they formed into cystic EBs that would eventually differentiate into the three embryonic germ layers.Evaluation of the EBs in terms of morphology and potential to differentiate indicated that they were typical in structure and could generate various cell types;they were also able to form into tissue-like structures.Moreover,with introduction of ascorbic acid,ES cells differentiated into cardiomyocytes efficiently and started contracting synchronously at day 19.The results demonstrated that collagen/Matrigel scaffolds supported EBs formation and their subsequent differentiation in a single three dimensional environment. | Jin Zhou Ye Zhang Qiuxia Lin Zhiqiang Liu Haibin Wang Cuimi Duan Yanmeng Wang Tong Hao Kmwu Wu Changyong Wang | 2010 | Journal of Genetics and Genomics2010,37,7: | 4 |
| 7 | Multifunctional geometric phase optical element for high-efficiency full Stokes imaging polarimetry显示文摘Polarization imaging finds applications in many areas, such as photoelasticity, ellipsometry, and biomedical imaging. A compact, snapshot, and high-efficiency imaging polarimeter is highly desirable for many applications.Here, based on a single multifunctional geometric phase optical element(GPOE), a new method is proposed for high-efficiency snapshot imaging polarimetry. With tailored spatially varying orientation of each anisotropic unit cell, the GPOE works highly efficiently as both a spin sorter and a half-wave plate, enabling snapshot retrieving of a full Stokes vector of incident light. The designed GPOE is implemented in the form of liquid crystal fabricated with a photo-alignment technology, and its application in imaging polarimetry is experimentally demonstrated by retrieving full Stokes parameters of a cylinder vector beam. This method can also work in the form of plasmonic or dielectric metasurfaces, enabling ultra-compact polarization detection systems by monolithic integration with other devices such as metalenses. | YANMENG DAI YUQUAN ZHANG YOUPENG XIE DAPENG WANG XIANYOU WANG ITING LEI CHANGJUN MIN XIAOCONG YUAN | 2019 | Photonics Research2019,7,9: | 3 |
| 8 | Validation results of NmF2 and hmF2 derived from ionospheric density profiles of GNOS on FY-3C satellite显示文摘The first Global Navigation Satellite System Occultation Sounder(GNOS) which is compatible of both Bei Dou System(BDS)and Global Positioning System(GPS) was successfully launched into orbit onboard the Feng Yun 3 C satellite(FY-3 C) on September 23, 2013, and it has already gathered a large amount of ionosphere radio occultation(RO) data so far. However, the detailed analysis and validation of GPS ionosphere RO data have not been done up to now. Therefore, this paper discusses the configuration of the FY-3 C GNOS, the methods and results of GPS ionosphere occultation processment, the quality analysis of the GPS ionosphere RO products, and the precision consistency between the GNOS GPS ionosphere RO product and ionosonde data. The peak electron density(Nm F2) correlation coefficient is 0.97, the corresponding standard deviation is 16.08%. The peak value altitude(hm F2) correlation coefficient is 0.89, and the corresponding standard deviation is 23.79 km. The in-orbit operation of GNOS provides a basis data set for the monitoring, forecasting and research of ionosphere's space weather. | YANG GuangLin SUN YueQiang BAI WeiHua ZHANG XiaoXin LIU CongLiang MENG XiangGuang BI YanMeng WANG DongWei ZHAO DanYang | 2018 | Science China(Technological Sciences)2018,61,9: | 2 |
| 9 | Enhanced perovskite electronic properties via A-site cation engineering显示文摘Organic-inorganic halide perovskites have emerged as excellent candidates for low-cost photovoltaics and optoelectronics.While the predominant recent trend in designing perovskites for efficient and stable solar cells has been to mix different A-site cations,the role of A-site cations is still limited to tune the lattice and bandgap of perovskites.Herein we compare the optoelectronic properties of acetamidinum(Ace)and guanidinium(Gua)mixed methylammonium lead iodide perovskites and shed a light on the hidden role of A-site cation on the carrier mobility of mixed-cation lead iodide perovskites.The cations do not affect the bandgap of the perovskites since the orbitals from Ace and Gua do not contribute to the band edges of the material.However,the mobility of the Ace mixed perovskite is significantly enhanced to be an order of magnitude higher than that of the pristine perovskite.We apply the Ace mixed perovskite in hole-conductor-free printable mesoscopic perovskite solar cells and obtain a stabilized PCE of over 18%(certified 17.7%),which is the highest certified efficiency so far. | Xufeng Xiao Yanmeng Chu Chunyu Zhang Zhihui Zhang Zexiong Qiu Cheng Qiu Huaixing Wang Anyi Mei Yaoguang Rong Gengzhao Xu Yue Hu Hongwei Han | 2021 | Fundamental Research2021,1,4: | 2 |
| 10 | Fast CO_(2) Retrieval Using a Semi-Physical Statistical Model for the High-Resolution Spectrometer on the Fengyun-3D Satellite显示文摘China’s Fengyun-3D meteorological satellite launched in December 2016 carries the high-resolution greenhouse-gases absorption spectrometer(GAS)aimed at providing global observations of carbon dioxide(CO_(2)).To date,GAS is one of the few instruments measuring CO_(2) from the near-infrared spectrum.On orbit,the oxygen(O_(2))A band suffers a disturbance,and the signal-to-noise ratio(SNR)is significantly lower than the nominal specification.This leads to difficulties in the retrieval of surface pressure and hence a degradation of the retrieval of the column-averaged CO_(2) dry air mole fraction(XCO_(2))if a full physics retrieval algorithm is used.Thus,a fast CO_(2) inverse method,named semi-physical statistical algorithm,was developed to overcome this deficiency.The instrument characteristics,the semi-physical statistical algorithm,and the results of comparison with ground-based measurements over land were introduced in this paper.XCO_(2) can be obtained from three bands,namely,the O_(2) A,weak CO_(2),and strong CO_(2) bands,with compensation from the Medium Resolution Spectral Imager-2(MERSI-2)products,ECMWF Reanaly-sis v5(ERA-5)data,and Total Carbon Column Observing Network(TCCON)data.The eigenvectors of covariance matrices and the least square fits were used to derive retrieval coefficients and yield cloud-free solutions.In addition to the GAS radiance,some key factors necessary for the accurate estimations of XCO_(2) were also taken as input information(e.g.,air mass,surface pressure,and a priori XCO_(2)).The global GAS XCO_(2) restricted over land was compared against the simultaneously collocated observations from TCCON.The retrieval algorithm can mitigate the issue caused by the low SNR of the O_(2) A band to a certain extent.Overall,through site-by-site comparisons,GAS XCO_(2) agreed well with the average precision(1σ)of 1.52 ppm and bias of−0.007 ppm.The seasonal variation trends of GAS XCO_(2) can be clearly seen at TCCON sites on the 1-yr timescale. | Yanmeng BI Peng ZHANG Zhongdong YANG Qian WANG Xingying ZHANG Chengbao LIU Pengmei XU Lizhou HOU Junyu KE Naiqiang ZHANG | 2022 | Journal of Meteorological Research2022,36,2: | 2 |

| 12 | An iron-dependent form of non-canonical ferroptosis induced by labile iron显示文摘Ferroptosis is a recently identified iron-dependent form of nonapoptotic cell death characterized by reactive oxygen species(ROS) generation and lipid peroxidation.Here,we report a novel iron-dependent form of ferroptosis induced by labile iron and investigate the mechanism underlying this process.We find that labile iron-induced ferroptosis is distinct from canonical ferroptosis and is linked to the mitochondrial pathway.Specifically,the mitochondrial calcium uniporter mediates the ferroptosis induced by labile iron.Interestingly,cells undergoing labile iron-induced ferroptosis exhibit cytoplasmic features of oncosis and nuclear features of apoptosis.Furthermore,labile iron-induced ferroptosis involves a unique set of genes.Finally,labile ironinduced ferroptosis was observed in liver subjected to acute iron overload in vivo.Our study reveals a novel form of ferroptosis that may be implicated in diseases caused by acute injury. | Yanmeng Li Qin Ouyang Wei Chen Ke Liu Bei Zhang Jingyi Yao Song Zhang Junying Ding Min Cong Anjian Xu | 2023 | Science China(Life Sciences)2023,66,3: | 1 |
| 13 | The Role of Dihydroresveratrol in Enhancing the Synergistic Effect of Ligilactobacillus salivarius Liol and Resveratrol in Ameliorating Colitis in Mice显示文摘Currently approved therapeutical strategies for inflammatory bowel diseases(IBD)suffer from variable efficacy and association with risk of serious side effects.Therefore,efforts have been made in searching for alternative therapeutics strategies utilizing gut microbiota manipulation.In this study,we show that the probiotic strain Ligilactobacillus salivarius Li01(Li01)and the phytochemical prebiotic resveratrol(RSV)have synergistic effect in ameliorating colitis in mice.Oral coadministration of Li01(109 CFU/d)and RSV(1.5 g/kg/d)promoted restoration of various inflammatory injuries and gut microbiota composition,exhibiting a favorable anti-inflammatory effect in DSS-induced colitis mice.The combination treatment was associated with reductions in the levels of proinflammatory cytokines IL-1βand IL-6 and increases in the levels of the anti-inflammatory cytokine IL-17A in mouse serum.Moreover,the combination treatment was found to alter the composition and metabolism of the gut microbiota,especially influencing the production of short chain fatty acids and anti-inflammatory related molecules.The mechanism underlying the improved anti-inflammatory effect from the RSV and Li01 combination treatment was found to be associated with the environmental sensor mammalian aryl hydrocarbon receptor(AHR)and tryptophan metabolism pathway.Administration of RSV in combination with Li01 in different mouse model led to enhanced conversion of RSV into metabolites,including dihydroresveratrol(DHR),resveratrol-sulfate,and resveratrol-glucuronide.DHR was found to be the dominant metabolite of RSV in conventional and colitis mice.An increased DHR/RSV ratio was confirmed to activate AHR and contribute to an enhanced anti-inflammatory effect.DHR is considered as a potential AHR ligand.The DHR/RSV ratio also affected the serotonin pathway by controlling the expression of Tph1,SERT,and 5-HT7R leading to amelioration of colitis in mice.Our data suggest that treatment with a combination of Li01 and RSV has potential as a therapeutic strategy for IBD;further investigation of this combination in clinical settings is warranted. | Yiqiu Fei Shuobo Zhang Shengyi Han Bo Qiu Yanmeng Lu Weixing Huang Fang Li Deying Chen Bjorn Berglund Hang Xiao Lanjuan Li Mingfei Yao | 2022 | Research2022,,4: | 1 |

| 18 | Facilitated tip-enhanced Raman scattering by focused gap-plasmon hybridization显示文摘Tip-enhanced Raman scattering(TERS)spectroscopy is a nondestructive and label-free molecular detection approach that provides high sensitivity and nanoscale spatial resolution.Therefore,it has been used in a wide array of applications.We demonstrate a gap-plasmon hybridization facilitated by a bottom-illuminated TERS configuration.The gap-plasmon hybridization effect is first performed with the finite-difference time-domain method to optimize the parameters,and experiments are then conducted to calibrate the performance.The results demonstrate an enhancement factor of 1157 and a spatial resolution of 13.5 nm.The proposed configuration shows great potential in related surface imaging applications in various fields of research. | HOUKAI CHEN YUQUAN ZHANG YANMENG DAI CHANGJUN MIN SIWEI ZHU XIAOCONG YUAN | 2020 | Photonics Research2020,8,2: | 1 |
| 19 | Influence of Texture on Hall-Petch Slope in Hot-extruded AZ31 Magnesium Alloys显示文摘To study the influence of texture on Hall-Petch slope,the Hall-Petch relationships of two hot-extruded AZ31 alloys(A117 and A189)were determined by the measurement of yield strength at room temperature.To determine the real texture difference,the texture changes were facilitated by the variation of extrusion ratio and demonstrated by the actual grain orientation distributions.The A117 alloys exhibited higher Hall-Petch slope in comparison of A187 in the condition of tension and compression,because A117 alloys had lower volume fraction of grains in the range of basal pole 75°-90°.The Hall-Petch slope differences for both alloys were analyzed and discussed by boundary obstacle against deformation propagation in grains with various orientation.Due to the higher volume fraction of grains in the range of basal pole 75°-90°in A189,the effect of hindering dislocation slip or twinning propagation by grains boundary was weaker than of A117. | 王岭 ZHAO Yiquan WANG Yanmeng SUN Chao CHEN Hongmei ZHANG Jing ZHAO Mei LIU Ying WANG Yinong | 2023 | Journal of Wuhan University of Technology(Materials Science)2023,38,4: | 0 |
| 20 | Unveiling the effect of amino acids on the crystallization pathways of methylammonium lead iodide perovskites显示文摘Multifunctional additives are widely used to improve crystallization and to passivate defects in perovskite solar cells. The roles of these additives are usually related to the various functional groups contained in such additives. Here, we introduce a serious of analogues of amino acids into methylammonium lead iodide perovskites and find they play different roles in the crystallization process despite the fact that these additives share exactly the same terminal groups, namely one amino group and one carboxyl group. The corresponding crystallization pathways are established for the first time via monitoring the time-resolved phase formation and transformation. We find that avoiding the rapid formation of perovskites from precursor solution can facilitate the uniform nucleation and growth of perovskite crystals with enhanced crystallinity and reduced defects. Further, we find the different crystallization behaviors probably arise from the inherent structural characteristic of these additives, leading to different interactions in the precursors. This study unveils the effects of amino acids on the liquid–solid crystallization process and helps better understand the role of multifunctional additives beyond their functional groups. | Wenhao Zhang Jiankang Du Weihua Zhang Yanmeng Chu Anyi Mei Yaoguang Rong Xinyu Gao Hongwei Han Yue Hu | 2022 | Journal of Energy Chemistry2022,31,6: | 0 |
