| 1 | Distribution and Ecological Risk Assessment of HCHs and DDTs in Surface Seawater and Sediment of the Mariculture Area of Jincheng Bay,China显示文摘The distribution of hexachlorocyclohexanes(HCHs) and dichlorodiphenyltrichloroethanes(DDTs) in the surface seawater and sediment of Jincheng Bay mariculture area were investigated in the present study. The concentration of total HCHs and DDTs ranged from 2.98 to 14.87 ng L-1 and were < 0.032 ng L-1, respectively, in surface seawater, and ranged from 5.52 to 9.43 and from 4.11 to 6.72 ng g-1, respectively, in surface sediment. It was deduced from the composition profile of HCH isomers and DDT congeners that HCH residues derived from a mixture of technical-grade HCH and lindane whereas the DDT residues derived from technical-grade DDT and dicofol. Moreover, both HCH and DDT residues may mainly originate from historical inputs. The hazard quotient of α-HCH, β-HCH, γ-HCH and δ-HCH to marine species was 0.030, 0.157, 3.008 and 0.008, respectively. It was estimated that the overall probability of adverse biological effect from HCHs was less than 5%, indicating that its risk to seawater column species was low. The threshold effect concentration exceeding frequency of γ-HCH, p,p'-DDD, p,p'-DDE and p,p'-DDT in sediment ranged from 8.3% to 100%, and the relative concentration of the HCH and DDT mixture exceeded their probable effect level in sediment. These findings indicated that the risk to marine benthos was high and potentially detrimental to the safety of aquatic products, e.g., sea cucumber and benthic shellfish. | HU Yanbing SUN Shan SONG Xiukai MA Jianxin RU Shaoguo | 2015 | Journal of Ocean University of China2015，14，2： | 7 |
| 2 | Accuracy Analysis and Design of A3 Parallel Spindle Head显示文摘As functional components of machine tools, parallel mechanisms are widely used in high efficiency machining of aviation components, and accuracy is one of the critical technical indexes. Lots of researchers have focused on the accuracy problem of parallel mechanisms, but in terms of controlling the errors and improving the accuracy in the stage of design and manufacturing, further efforts are required. Aiming at the accuracy design of a 3-DOF parallel spindle head(A3 head), its error model, sensitivity analysis and tolerance allocation are investigated. Based on the inverse kinematic analysis, the error model of A3 head is established by using the first-order perturbation theory and vector chain method. According to the mapping property of motion and constraint Jacobian matrix, the compensatable and uncompensatable error sources which affect the accuracy in the end-effector are separated. Furthermore, sensitivity analysis is performed on the uncompensatable error sources. The sensitivity probabilistic model is established and the global sensitivity index is proposed to analyze the influence of the uncompensatable error sources on the accuracy in the end-effector of the mechanism. The results show that orientation error sources have bigger effect on the accuracy in the end-effector. Based upon the sensitivity analysis results, the tolerance design is converted into the issue of nonlinearly constrained optimization with the manufacturing cost minimum being the optimization objective. By utilizing the genetic algorithm, the allocation of the tolerances on each component is finally determined. According to the tolerance allocation results, the tolerance ranges of ten kinds of geometric error sources are obtained. These research achievements can provide fundamental guidelines for component manufacturing and assembly of this kind of parallel mechanisms. | NI Yanbing ZHANG Biao SUN Yupeng ZHANG Yuan | 2016 | Chinese Journal of Mechanical Engineering2016，29，2： | 6 |

| 4 | Orbital ordering and fluctuations in a kagome superconductor CsV_(3)Sb_(5)显示文摘Recently,competing electronic instabilities,including superconductivity and density-wave-like order,have been discovered in vanadium-based kagome metals AV_(3)Sb_(5)(A=K,Rb,Cs)with a nontrivial band topology.This finding stimulates considerable interest to study the interplay of these competing electronic orders and possible exotic excitations in the superconducting state.Here,we performed51V and133Cs nuclear magnetic resonance(NMR)measurements on a CsV_(3)Sb_(5)single crystal to clarify the nature of density-wave-like transition in these kagome superconductors.A first-order structural transition is unambiguously revealed below T_(s)~94 K by observing the sudden splitting of Knight shift in^(51)V NMR spectrum.Moreover,combined with^(133)Cs NMR spectrum,the present result confirms a three-dimensional structural modulation.By further analyzing the anisotropy of Knight shift and 1/T_(1)T at^(51)V nuclei,we proposed that the orbital order is the primary electronic order induced by the firstorder structural transition,which is supported by further analysis on electric field gradient at^(51)V nuclei.In addition,the evidence for possible orbital fluctuations is also revealed above T_(s).The present work sheds light on a rich orbital physics in kagome superconductors AV_(3)Sb_(5). | DianWu Song LiXuan Zheng FangHang Yu Jian Li LinPeng Nie Min Shan Dan Zhao ShunJiao Li BaoLei Kang ZhiMian Wu YanBing Zhou KuangLv Sun Kai Liu XiGang Luo ZhenYu Wang JianJun Ying XianGang Wan Tao Wu XianHui Chen | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，4： | 2 |

| 7 | “Top-down” and “bottom-up” strategies for wafer-scaled miniaturized gas sensors design and fabrication显示文摘Manufacture of large-scale patterned nanomaterials via top-down techniques,such as printing and slurry coating,have been used for fabrication of miniaturized gas sensors.However,the reproducibility and uniformity of the sensors in wafer-scale fabrication are still a challenge.In this work,a“top-down”and“bottom-up”combined strategy was proposed to manufacture wafer-scaled miniaturized gas sensors with high-throughput by in-situ growth of Ni(OH)2 nanowalls at specific locations.First,the micro-hotplate based sensor chips were fabricated on a two-inch(2″)silicon wafer by micro-electro-mechanical-system(MEMS)fabrication techniques(“top-down”strategy).Then a template-guided controllable de-wetting method was used to assemble a porous thermoplastic elastomer(TPE)thin film with uniform micro-sized holes(relative standard deviation(RSD)of the size of micro-holes<3.5%,n>300),which serves as the patterned mask for in-situ growing Ni(OH)2 nanowalls at the micro-hole areas(“bottom-up”strategy).The obtained gas microsensors based on this strategy showed great reproducibility of electric properties(RSD<0.8%,n=8)and sensing response toward real-time H _(2)S detection(RSD<3.5%,n=8). | Lin Liu Yingyi Wang Fuqin Sun Yanbing Dai Shuqi Wang Yuanyuan Bai Lianhui Li Tie Li Ting Zhang Sujie Qin | 2020 | Microsystems & Nanoengineering2020，6，1： | 1 |

| 18 | Birefringent response of graphene oxide film structurized via femtosecond laser显示文摘In-plane birefringent materials present an effective modulation of the optical properties and more degrees of freedom for the signal detection in low dimension,and thus remain a hot topic in realizing the integrated,miniature,and flexible devices for multiple applications.Here,the artificial in-plane birefringence properties have been successfully achieved on a graphene oxide film by a novel femtosecond laser lithography method,which provides a high-speed,large-area,and regular subwavelength gratings(~380 nm)fabrication and photoreduction.The obtained sample manifests an evident optical birefringence(~0.18)and anisotropic photoresponse(~1.21)in the visible range,both of which can be significantly modulated by either the structural morphology or the degree of oxide reduction.Based on the analysis of effective-medium theory and measurements of angle-resolved polarized Raman spectroscopy,the artificial in-plane birefringence is originated from various optical responses of the periodic subwavelength structures for the incident light with different polarization states.This technique shows great advantages for the fabrication of integrated in-plane polarization-dependent devices,which is expected to solve the problems in this field,such as the deficient selection of materials,complex design of micro/nanostructure,and inflexible processing technology. | Tingting Zou Bo Zhao Wei Xin Feiyue Wang Hongbo Xie Yuhang Li Yuwei Shan Kun Li Yanbing Sun Jianjun Yang | 2022 | Nano Research2022，15，5： | 1 |

| 20 | Elodexanthones A—J, Isoprenylated Xanthone Derivatives with Diverse Skeletons and Bioactivities from Hypericum elodeoides显示文摘Elodexanthones A—J (1—10), two pairs of rearranged isoprenylated xanthone enantiomers with an unprecedent 6/6/5/6 tetracyclic core (1—2) along with seven new isoprenylated xanthones (3—9) and a pair of phenylpropanoid xanthones (10), were purified and enantio-separated from the whole plant of Hypericum elodeoides. Their structures including absolute configurations were characterized by the comprehensive analysis of NMR, HRESIMS, NMR calculations, and ECD calculations. Through Bayer-Villiger oxidation, Claisen condensation and electrophilic addition, the rearranged skeletons of elodexanthones A—B (1—2) were generated from isoprenylated xanthone precursors. The bioactivities evaluation exhibited that compounds 3, 5, 8—10 showed anti-inflammatory activity with the IC_(50) values in the range of 9.53—34.39 μmol/L, and compounds 3—7, and 9 showed notable α-glucosidase inhibitory activity (IC_(50): 6.02—257.11 μmol/L). | Yanbing Mu Yaqi Li Qiji Li Wenjun Xu Yunpeng Sun Siyuan Wang Letian Cui Lingyi Kong Jun Luo | 2022 | Chinese Journal of Chemistry2022，40，24： | 1 |
