1Reaction environment self-modification on low-coordination Ni^(2+)octahedra atomic interface for superior electrocatalytic overall water splitting显示文摘Large scale synthesis of high-efficiency bifunctional electrocatalyst based on cost-effective and earth-abundant transition metal for overall water splitting in the alkaline environment is indispensable for renewable energy conversion.In this regard,meticulous design of active sites and probing their catalytic mechanism on both cathode and anode with different reaction environment at molecular-scale are vitally necessary.Herein,a coordination environment inheriting strategy is presented for designing low-coordination Ni^(2+)octahedra(L-Ni-8)atomic interface at a high concentration(4.6 at.%).Advanced spectroscopic techniques and theoretical calculations reveal that the self-matching electron delocalization and localization state at L-Ni-8 atomic interface enable an ideal reaction environment at both cathode and anode.To improve the efficiency of using the self-modification reaction environment at L-Ni-8,all of the structural features,including high atom economy,mass transfer,and electron transfer,are integrated together from atomic-scale to macro-scale.At high current density of 500 mA/cm2,the samples synthesized at gram-scale can deliver low hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)overpotentials of 262 and 348 mV,respectively.Kaian Sun Lei Zhao Lingyou Zeng Shoujie Liu Houyu Zhu Yanpeng Li Zheng Chen Zewen Zhuang Zhaoling Li Zhi Liu Dongwei Cao Jinchong Zhao Yunqi Liu Yuan Pan Chen Chen 2020Nano Research2020,13,11:12
2Assessment of potential dermal and inhalation exposure of workers to the insecticide imidacloprid using whole-body dosimetry in China显示文摘In China, although improvements to the pesticide registration process have been made in la thirty years, no occupational exposure data are required to obtain a commercial license for pesticide product. Consequently, notably little research has been conducted to establish a exposure assessment procedure in China. The present study monitored the potential derm operator exposure from knapsack electric sprayer wheat field application of imidacloprid Liaocheng City, Shandong Province and in Xinxiang City, Henan Province, China, usin whole-body dosimetry. The potential inhalation exposure was determined using a person air pump and XAD-2 sample tubes. The analytical method was developed and validate including such performance parameters as limits of detection and quantification, linear rang recovery and precision. The total potential dermal and inhalation exposures were 14.20, 16.815.39 and 20.78 m L/hr, respectively, for the four operators in Liaocheng and Xinxian corresponding to 0.02% to 0.03% of the applied volume of spray solution. In all trials, the low part(thigh, lower leg) of the body was the most contaminated, accounting for approximate76% to 88% of the total exposure. The inhalation exposure was less than 1% of the tot exposure. Such factors as the application pattern, crop type, spray equipment, operat experience and climatic conditions have been used to explain the exposure distribution ov the different parts of the body. As indicated by the calculated Margin of Exposure, the typic wheat treatment scenarios when a backpack sprayer was used are considered to be safe terms of imidacloprid exposure.Lidong Cao Bo Chen Li Zheng Dongwei Wang Feng Liu Qiliang Huang 2015Journal of Environmental Sciences2015,27,1:4

5Structural optimization design of semi-rigid base asphalt pavement using modulus matching criterion and multi-indicator range analysis显示文摘Damage to semi-rigid base asphalt pavement is related to improper matching of the pavement structure moduli.This study mainly focused on the modulus matching of structural layers and the development of a pavement structure optimization method.First,the modulus loss of existing pavement structures was analysed,and a three-dimensional finite element model was established based on the existing pavement.Second,the influence of the modulus of each structural layer on the mechanical response indicators and fatigue life was analysed.Based on the results,a pavement structure design method using the smoothness of the stress-strain curve as the modulus matching criterion of the structural layers was proposed.And it was found that a strain convex point was present and that the stress mutation between the structural layers was significant when the modulus matching of the pavement structure was reasonable.Further,the evaluation indicators were divided into two groups,namely,mechanical indicators and fatigue life indicators.And it was proposed an optimized pavement structure design method based on modulus matching and multi-indicator range analysis.Finally,the optimal modulus combination of pavement structure was determined by this method.The research systematically studied the influence of the modulus of each structural layer on the mechanical response and fatigue life of the pavement,and proposed the concept and specific executive criteria of modulus matching for the first time.Meanwhile,it also provided an effective optimization method for pavement structure design.Zhihao Yang Linbing Wang Dongwei Cao Yinghao Miao Hailu Yang 2024Journal of Traffic and Transportation Engineering(English Edition)2024,11,1:0

7Liver X receptorβis required for the survival of single-positive thymocytes by regulating IL-7Rαexpression显示文摘Liver X receptors(LXRs)are known as key transcription factors in lipid metabolism and have been reported to play an important role in T-cell proliferation.However,whether LXRs play a role in thymocyte development remains largely unknown.Here,we demonstrated that LXRβdeficiency caused a reduction in single-positive(SP)thymocytes,whereas the transitions from the double-negative to SP stage were normal.Meanwhile,LXRβ-null SP thymocytes exhibited increased apoptosis and impairment of the IL-7Rα-Bcl2 axis.In addition,the LXR agonist T0901317 promoted the survival of SP thymocytes with enhanced IL-7Rαexpression in wild-type mice but not in LXRβ-deficient mice.Mechanistically,LXRβpositively regulated the expression of IL-7Rαvia direct binding to the Il7r allele in SP thymocytes,and forced expression of IL-7Rαor Bcl2 restored the survival of LXRβ-defective SP thymocytes.Thus,our results indicate that LXRβfunctions as an important transcription factor upstream of IL-7Rαto promote the survival of SP thymocytes.Huang Huang Xiaoping Wu Dongwei Meng Yizhou Feng Lan Zhou Zhenyu Liu Shupei Tang Xueqin Li Yi Cao Haiyang He Zhunyi Xie Jingbo Zhang Yongwen Chen Tingting Zhao Yuzhang Wu Xinyuan Zhou 2021Cellular & Molecular Immunology2021,18,8:0
