| 1 | A comparative study of Mn/CeO_2,Mn/ZrO_2 and Mn/Ce-ZrO_2 for low temperature selective catalytic reduction of NO with NH_3 in the presence of SO_2 and H_2O显示文摘Ce-ZrO2 is a widely used three-way catalyst support.Because of the large surface area and excellent redox quality,Ce-ZrO2 may have potential application in selective catalytic reduction(SCR) systems.In the present work,Ce-ZrO2 was introduced into a low-temperature SCR system and CeO2 and ZrO2 supports were also introduced to make a contrastive study.Mn/CeO2,Mn/ZrO2 and Mn/Ce-ZrO2 were prepared by impregnating these supports with Mn(NO3)2 solution,and have been characterized by N2-BET,XRD,TPR,TPD,XPS,FT-IR and TG.The activity and resistance to SO2 and H2O of the catalysts were investigated.Mn/Ce-ZrO2 and Mn/CeO2 were proved to have better low-temperature activities than Mn/ZrO2,and yielded 98.6% and 96.8% NO conversion at 180°C,respectively.This is mainly because Mn/Ce-ZrO2 and Mn/CeO2 had higher dispersion of manganese oxides,better redox properties and more weakly adsorbed oxygen species than Mn/ZrO2.In addition,Mn/Ce-ZrO2 showed a good resistance to SO2 and H2O and presented 87.1% NO conversion,even under SO2 and H2O treatment for 6 hours,and the activity of Mn/Ce-ZrO2 was almost restored to its original level after cutting off the injection of SO2 and H2O.This was due to the weak water absorption and weak sulfation process on the surface of the catalyst. | Boxiong Shen Xiaopeng Zhang Hongqing Ma Yan Yao Ting Liu | 2013 | Journal of Environmental Sciences2013，25，4： | 30 |
| 2 | Comparative analysis of the complete chloroplast genome among Prunus mume,P.armeniaca,and P.salicina显示文摘Prunus mume Sieb.et Zucc.,P.armeniaca L.,and P.salicina L.are economically important fruit trees in temperate regions.These species are taxonomically perplexing because of shared interspecific morphological traits and variation,which are mainly attributed to hybridization.The chloroplast is cytoplasmically inherited and often used for evolutionary studies.We sequenced the complete chloroplast genomes of P.mume,P.armeniaca,and P.salicina using Illumina sequencing followed by de novo assembly.The three chloroplast genomes exhibit a typical quadripartite structure with conserved genome arrangement,structure,and moderate divergence.The lengths of the genomes are 157,815,157,797,and 157,916 bp,respectively.The length of the large single-copy region(LSC)region is 86,113,86,283,and 86,122 bp,and the length of the SSC region is 18,916,18,734,and 19,028 bp;the IR region is 26,393,26,390,and 26,383 bp,respectively.Each of the three chloroplast genomes encodes 133 genes,including 94 protein-coding,31 tRNA,and eight rRNA genes.Differential gene analysis for the three species revealed that trnY-ATA is a unique gene in P.armeniaca;in contrast,the gene trnI-TAT is only present in P.mume and P.salicina,though the position of the gene in these chloroplast genomes differs.Further comparative analysis of the complete chloroplast genome sequences revealed that the ORF genes and the sequences of linked regions rps16 and atpA,atpH and atpI,trnc-GCA and psbD,ycf3 and atpB,and rpL32 and ndhD are significantly different and may be used as molecular markers in taxonomic studies.Phylogenetic evolution analysis of the three species suggests that P.mume has a closer genetic relationship to P.armeniaca than to P.salicina. | Song Xue Ting Shi Wenjie Luo Xiaopeng Ni Shahid Iqbal Zhaojun Ni Xiao Huang Dan Yao Zhijun Shen Zhihong Gao | 2019 | Horticulture Research2019，6，1： | 10 |

| 5 | A proposed direct measurement of cross section at Gamow window for key reaction 19F(p,α) 16O in Asymptotic Giant Branch stars with a planned accelerator in CJPL显示文摘In 2014, the National Natural Science Foundation of China(NSFC) approved the Jinping Underground Nuclear Astrophysics laboratory(JUNA) project, which aims at direct cross-section measurements of four key stellar nuclear reactions right down to the Gamow windows. In order to solve the observed fluorine overabundances in Asymptotic Giant Branch(AGB) stars, measuring the key ^(19)F( p,α)^(16)O reaction at effective burning energies(i.e., at Gamow window) is established as one of the scientific research sub-projects.

| 6 | Research on Data Fusion of Adaptive Weighted Multi-Source Sensor显示文摘Data fusion can effectively process multi-sensor information to obtain more accurate and reliable results than a single sensor.The data of water quality in the environment comes from different sensors,thus the data must be fused.In our research,self-adaptive weighted data fusion method is used to respectively integrate the data from the PH value,temperature,oxygen dissolved and NH3 concentration of water quality environment.Based on the fusion,the Grubbs method is used to detect the abnormal data so as to provide data support for estimation,prediction and early warning of the water quality. | Donghui Li Cong Shen Xiaopeng Dai Xinghui Zhu Jian Luo Xueting Li Haiwen Chen Zhiyao Liang | 2019 | Computers, Materials & Continua2019，，9： | 2 |
| 7 | Snow and ice thicknesses derived from Fast Ice Prediction System Version 2.0(FIPS V2.0)in Prydz Bay,East Antarctica:comparison with in-situ observations显示文摘In this paper,snow and ice thickness products derived from an updated Fast Ice Prediction System Version 2.0(FIPS V2.0)in Prydz Bay,East Antarctica,are introduced and compared with in-situ obser-vations.FIPS V2.0 is comprised of a newly-developed snowdrift parameterization compared to the original FIPS V1.0.The simulation domain covers the entire fast ice region in Prydz Bay and is config-ured to 720 grid cells,with a spatial resolution of 0.125°.The ERAInterim reanalysis from the European Centre for Medium-Range Weather Forecasting(ECMWF)were used as the atmospheric forcing.The in-situ observations were obtained near Zhongshan Station by the wintering team,and the measurement frequency of the snow and ice thicknesses was around one week.Both the FIPS V2.0 pro-ducts and in-situ observations introduced in this paper cover the time periods from 2012 to 2016.The primary assessments based on the in-situ observations show that FIPS V2.0 has mean biases of 0.01±0.07 m and 0.23±0.09 m for snow and ice thickness simula-tions,respectively.The results indicate that the updated FIPS V2.0 produces a reasonable snow thickness due to the newly-developed snowdrift parameterization,but it overestimates the ice thickness due to the cold bias in the air temperature forcing.These 2-D snow and ice thickness distributions provide important references for sea ice thermodynamic studies,remote sensing validations,and ice-breaker navigation assessments in this region.The dataset is avail-able at http://gffzza4c772bdab62464fhup9p9v5bfppx6nb6.ffgz.tsg.suse.edu.cn/10.11922/sciencedb.j00076.00066. | Jiechen Zhao Jingjing Cheng Zhongxiang Tian Xiaopeng Han Hui Shen Guanghua Hao Honglin Guo Qi Shu | 2022 | Big Earth Data2022，6，4： | 2 |

| 14 | Thermal detection of surface plasmons on gold nanohole arrays显示文摘We used a thin-film thermocouple to detect the thermal effect of surface plasmons excited in Au nanohole array structures.We found that the thermal electromotive force of Au film with periodic nanohole structures is three times greater than that of a bare Au film for 785-nm laser excitation at a given power.This effect is caused by the resonant excitation of localized surface plas- mons in the nanoholes.In addition,we found that the thermal electromotive force(EMF)of the Au film with dumbbell-like na- nohole arrays depends strongly on the incident polarization.The thermal EMF is the greatest when the excitation light is polarized perpendicular to the long axis of the dumbbell. | ZHANG Wei LI ZhiPeng GUAN ZhiQiang SHEN Hao YU WenBo He WeiDong YAN XiaoPeng LI Ping XU HongXing | 2012 | Chinese Science Bulletin2012，57，1： | 0 |
| 15 | Constraining self-interacting dark matter with the full dataset of PandaX-II显示文摘Self-interacting dark matter(SIDM)is a leading candidate proposed to solve discrepancies between predictions of the prevailing cold dark matter theory and observations of galaxies.Many SIDM models predict the existence of a light force carrier that mediates strong dark matter self-interactions.If the mediator couples to the standard model particles,it could produce characteristic signals in dark matter direct detection experiments.We report searches for signals of SIDM models with a light mediator using the full dataset of the PandaX-II experiment,basing on a total exposure of 132 tonne-days.No significant excess over background is found,and our likelihood analysis leads to a strong upper limit on the dark matter-nucleon coupling strength.We further combine the PandaX-II constraints and those from observations of the light element abundances in the early universe,and show that direct detection and cosmological probes can provide complementary constraints on dark matter models with a light mediator. | Jijun Yang Abdusalam Abdukerim Wei Chen Xun Chen Yunhua Chen Chen Cheng Xiangyi Cui Yingjie Fan Deqing Fang Changbo Fu Mengting Fu Lisheng Geng Karl Giboni Linhui Gu Xuyuan Guo Ke Han Changda He Shengming He Di Huang Yan Huang Ran Huo Yanlin Huang Zhou Huang Xiangdong Ji Yonglin Ju Shuaijie Li Qing Lin Huaxuan Liu Jianglai Liu Xiaoying Lu Wenbo Ma Yugang Ma Yajun Mao Yue Meng Nasir Shaheed Kaixiang Ni Jinhua Ning Xuyang Ning Xiangxiang Ren Changsong Shang Guofang Shen Lin Si Andi Tan Anqing Wang Hongwei Wang Meng Wang QiuHong Wang Siguang Wang Wei Wang Xiuli Wang Zhou Wang Mengmeng Wu Shiyong Wu Weihao Wu Jingkai Xia Mengjiao Xiao Xiang Xiao Pengwei Xie Binbin Yan Yong Yang Chunxu Yu Hai-Bo Yu Jumin Yuan Ying Yuan Xinning Zeng Dan Zhang Tao Zhang Li Zhao Qibin Zheng Jifang Zhou Ning Zhou Xiaopeng Zhou | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，11： | 0 |
| 16 | Economics analysis of food waste treatment in China and its influencing factors显示文摘This study examines the economic benefits of food waste treatment projects in China and factors affecting them.National-level pilot projects for food waste treatment located in 29 cities were selected as samples.The economics of food waste recycling from the investors’perspective,in terms of investment during the construction phase and cost and benefit during the operation phase,was assessed.Results indicate that the average tonnage investment of food waste treatment projects was RMB 700.0±188.9 thousand yuan,with a profit to cost ratio of 0.08±0.37.This ratio increased to 0.95±0.57 following the application of government subsidies.It highlights the limited economic benefits of food waste treatment facilities,which rely on government subsidies to maintain their operations in China.Further analysis using a multi-factor analysis model revealed that regional location,service population size,processing technique,and urban income exerted varying impacts on the economy of food waste treatment.Population size exerted the highest impact(P=0.016)during the construction stage,and processing techniques notably influenced the project economy during the operation stage.The study highlights the need to prioritize service population size and processing techniques during economic decision-making and management of food waste recycling projects.The results of this study can serve as a valuable practical reference for guiding future policies regarding food waste treatment and related planning. | Ting Chen Yingying Zhao Xiaopeng Qiu Xiaoyan Zhu Xiaojie Liu Jun Yin Dongsheng Shen Huajun Feng | 2021 | Frontiers of Environmental Science & Engineering2021，15，2： | 0 |
| 17 | Broadband omnidirectional visible spectral metamaterials显示文摘Optical metamaterials offer the possibility of controlling the behavior of photons similarly to what has been done about electrons in semiconductors.However,most optical metamaterials are narrowband,and they achieve negative refraction within a small window of incident angles,making them impractical for common visible light systems that operate effectively over a wide range of frequencies and directions.Considerable resistive loss at the resonant frequency of these metamaterials further prevents them from being deployed in the real world.Here,we develop a novel metamaterial randomly assembled by a list of narrowband,omnidirectional,and ultralow-loss meta-cluster systems using a bottom-up approach.Weak interactions among numerous meta-cluster sets greatly broaden the effective bandwidth of the overall structure,exhibiting frequency selectivity and spatial modulation when responding to white-light illumination.We observe negative refraction in the 490–730 nm band,and observe an inverse Doppler effect at green,yellow,and red frequencies,across most of the visible spectrum.Our method allows for low-cost fabrication of sizable broadband omnidirectional three-dimensional metamaterial samples,which opens the door to the rapid development of optical metamaterials,micro–nano assembly and preparation,tunable optical device engineering,etc. | JING ZHAO XIANFENG WU DI CAO MINGCHAO ZHOU ZHIJIE SHEN XIAOPENG ZHAO | 2023 | Photonics Research2023，11，7： | 0 |
| 18 | Chemo-Biocascade Reactions Enabled by Metal-Organic Framework Micro-Nanoreactor显示文摘The one-pot combination of biocatalytic and chemocatalytic reactions represents an economically and ecologically attractive concept in the emerging cascade processes for manufacturing.The mutual incompatibility of biocatalysis and chemocatalysis,however,usually causes the deactivation of catalysts,the mismatching of reaction dynamic,and further challenges their integration into concurrent chemo-biocascades.Herein,we have developed a convenient strategy to construct versatile functional metal-organic framework micro-nanoreactors(MOF-MNRs),which can realize not only the encapsulation and protection of biocatalysts but also the controllable transmission of substances and the mutual communication of the incompatible chemo-biosystems.Importantly,the MOFs serving as the shell of MNRs have the capability of enriching the chemocatalysts on the surface and improving the activity of the chemocatalysts to sufficiently match the optimum aqueous reaction system of biocatalysts,which greatly increase the efficiency in the combined concurrent chemo-biocatalysis.Such strategy of constructing MOF-MNRs provides a unique platform for connecting the“two worlds”of chemocatalysis and biocatalysis. | Jing Zhang Yu Shen Na Jin Xiaopeng Zhao Hongfeng Li Ning Ji Yingjie Li Baoli Zha Lin Li Xikuang Yao Suoying Zhang Fengwei Huo Weina Zhang | 2023 | Research2023，，1： | 0 |
| 19 | Unidirectional transport in amorphous topological photonic crystals显示文摘Many works on topological insulators have focused on periodic lattice systems,where short-and long-range order is considered.Here we construct a two-dimensional amorphous photonic crystal with short-range order and a controllable level of long-range order and experimentally investigate the transport of topological edge states in this amorphous system.We demonstrate that topology properties remain constant with unidirectional edge state propagation,immune to specific disorder strength.The partition phenomena of edge states are also observed at the intersection of four topological channels in microwave experiments.This proposed amorphous configuration provides new opportunities to explore the relationship between short-range order and topology and may alleviate the fabrication difficulties of topological optical devices for practical applications. | Yuting Yang Xinyue Qian Liwei Shi Xiaopeng Shen Zhi Hong Hang | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，7： | 0 |
| 20 | Proteomic analysis of acute radiation-induced rectal injury in rats显示文摘Objective:To comprehensively elucidate overall protein alterations associated with acute radiation-induced rectal injury in rats.Methods:A rat model of acute radiation-induced rectal injury was established by irradiating rectal segments with a single dose of 17.5 Gy X-rays.These segments were then collected at 7 d and 10 d post-irradiation.Tandem mass tag-based quantitative proteomic analysis was then performed.Results:65,526 peptides were identified,corresponding to 8,088 proteins.Hematoxylin-eosin staining revealed characteristic epithelial cell degeneration and necrosis,intestinal gland atrophy and dilatation,and interstitial inflammatory cell infiltration.Inflammation was more pronounced in the 10 d irradiation group than in the 7 d irradiation group.Overall,127 up-and 108 downregulated proteins were identified at 7 d post-irradiation,and 122 up-and 44 downregulated proteins were identified at 10 d post-irradiation.Notably,17 up-and 6 downregulated proteins were consistently co-expressed at both time points.The expression of three of these proteins was validated via real-time quantitative PCR:polypeptide YY(Pyy),thymidylate synthase(Tyms),and tetraspanin(CD9).Tyms transcript levels were significantly higher in irradiated rectal tissues(P<0.05).Pyy transcript levels were significantly higher at both time points(P<0.05).Finally,CD9 mRNA expression was significantly lower in both the 7 d and 10 d irradiation groups(P<0.05).Conclusions:The potential targets were found to prevent and treat acute radiation-induced rectal injury in clinical practice. | Yue Zhu Jun Dai Xiaopeng Xu Yi Gao Weidong Shen Shuyu Zhang Pengfei Liu | 2023 | Radiation Medicine and Protection2023，4，3： | 0 |
