| 1 | An energy efficiency clustering routing protocol for WSNs in confined area显示文摘Wireless sensor networks (WSNs) are important application for safety monitoring in underground coal mines, which are difficult to monitor due to natural conditions. Based on the characteristic of limited energy for WSNs in confined underground area such as coal face and laneway, we presents an energy- efficient clustering routing protocol based on weight (ECRPW) to prolong the lifetime of networks. ECRPW takes into consideration the nodes' residual energy during the election process of cluster heads. The constraint of distance threshold is used to optimize cluster scheme. Furthermore, the protocol also sets up a routing tree based on cluster heads' weight. The results show that ECRPW had better perfor- mance in energy consumption, death ratio of node and network lifetime. | Sun Yanjing He Yanjun Zhang Beibei Liu Xue | 2011 | Mining Science and Technology2011,21,6: | 9 |

| 3 | Application of Avaatech X-ray fluorescence core-scanning in Sr/Ca analysis of speleothems显示文摘Application of X-ray fluorescence core-scanning(XRF-CS) on both marine and lake sediments has achieved remarkable results. However, its application has not been widely extended to the research on speleothems. In this study, we measure the Sr abundance and the Sr/Ca ratios of three stalagmites(two aragonite stalagmites, one calcite stalagmite) using the state-of-the-art fourth-generation Avaatech high-resolution XRF core scanner. Through comparisons among different scan paths and among different scan resolutions, as well as comparisons with inductively coupled plasma optical emission spectrometer(ICP-OES), Itrax XRF, and Artax XRF results, we confirm that the Avaatech XRF core scanner could precisely, quickly, and nondestructively analyze the high-resolution Sr abundance of speleothems. Furthermore, we combine the stalagmite δ^(18)O records to explore the paleoclimatic significance of the measured stalagmite Sr/Ca. | Dong LI Liangcheng TAN Fei GUO Yanjun CAI Youbin SUN Gang XUE Xing CHENG Hong YAN Hai CHENG R.Lawrence EDWARDS Yongli GAO Jessica KELLEY | 2019 | Science China Earth Sciences2019,62,6: | 7 |
| 4 | Nonselective etching of GaN/AlGaN heterostructures by Cl2/Ar/BCl3 inductively coupled plasmas显示文摘A systematic study of the nonselective and smooth etching of GaN/AIGaN het-erostructures was performed using C12/Ar/BCI3 inductively coupled plasmas (ICR).Nonselective etching can be realized by adjusting the BCI3 ratio in the Cl2/Ar/BCI3 mixture (20%—60%), increasing the ICR power and dc bias, and decreasing the chamber pressure. Surface morphology of the etched heterostructures strongly depends on the gas chemistry and the chamber pressure. Specifically, with the addition of 20% BCI3 to Cl2/Ar (4:1) gas mixture, nonselective etching of GaN/Al0.28Ga0.72N heterostructures at high etch rate is maintained and the surface root-mean-square (rms) roughness is reduced from 10.622 to 0.495 nm, which is smoother than the as-grown sample. Auger electron spectroscopy (AES) analysis shows that the effective removal of residual oxygen from the surface of AIGaN during the etching process is crucial to the nonselective and smooth etching of GaN/AIGaN herterostructures at high etch rate. | HAN Yanjun XUE Song WU Tong WU Zhen GUO Wenping LUO Yi HAO Zhibiao SUN Changzheng | 2004 | Science China(Technological Sciences)2004,47,2: | 6 |
| 5 | Epigenetics in the pathogenesis of diabetic nephropathy显示文摘Diabetic nephropathy(DN),which is a common microvascular complication with a high incidence in diabetic patients,greatly increases the mortality of patients.With further study on DN,it is found that epigenetics plays a crucial role in the pathophysiological process of DN.Epigenetics has an important impact on the development of DN through a variety of mechanisms,and promotes the generation and maintenance of metabolic memory,thus ultimately leading to a poor prognosis.In this review we discuss the methylation of DNA,modification of histone,and regulation of non-coding RNA involved in the progress of cell dysfunction,inflammation and fibrosis in the kidney,which ultimately lead to the deterioration of DN. | Xue Li Lihong Lu Wenting Hou Ting Huang Xiangyuan Chen Jie Qi Yanjun Zhao Minmin Zhu | 2022 | Acta Biochimica et Biophysica Sinica2022,54,2: | 6 |
| 6 | Au nanorods decorated TiO_(2)nanobelts with enhanced full solar spectrum photocatalytic antibacterial activity and the sterilization file cabinet application显示文摘TiO_(2)photocatalysts have been widely studied and applied for removing bacteria,but its antibacterial efficiency is limited to the ultraviolet(UV)range of the solar spectrum.In this work,we use the gold(Au)nanorods to enhance the visible and near-infrared(NIR)light absorption of TiO_(2)NBs,a typical UV light photocatalyst,thus the enhancement of its full solar spectrum(UV,visible and NIR)photocatalytic antibacterial properties is achieved.Preliminary surface plasmon resonance(SPR)enhancement photocatalytic antibacterial mechanism is suggested.On one hand,transverse and longitudinal SPR of Au NRs is beneficial for visible and NIR light utilization.On the other hand,Au NRs combined with TiO_(2)NBs to form the heterostructure,which can improve the photogenerated carrier separation and direct electron transfer increases the hot electron concentration while Au NRs as the electron channel can well restrain charge recombination.finally produces the high yield of radical oxygen species and exhibits a superior antibacterial efficiency.Furthermore,we design a sterilization file cabinet with Au NR/TiO_(2)NB heterostructures as the photocatalytic coating plates.Our study reveals that Au NR/TiO_(2)NB heterostructure is a potential candidate for sterilization of bacteria and archives protection. | Yingying Qin Yichen Guo Zhangqian Liang Yanjun Xue Xiaoli Zhang Lei Yang Jian Tian | 2021 | Chinese Chemical Letters2021,32,4: | 6 |
| 7 | The cotton WRKY transcription factor GhWRKY70 negatively regulates the defense response against Verticillium dahliae显示文摘WRKY transcription factors (TFs) play important roles in the regulation of biotic and abiotic stresses. However, the functions of most WRKY TFs in upland cotton (Gossypium hirsutum) are still unknown. In this study, we functionally identified a group Ⅲ WRKY transcription factor, GhWRKY70, in upland cotton. Reverse transcription-quantitative PCR analysis showed that GhWRKY70 expression was induced by Verticillium dahliae, salicylic acid (SA) and methyl jasmonate. Virus-induced gene silencing of GhWRKY70 increased the resistance of cotton to V. dahliae. Specifically, jasmonic acid (JA) response-associated genes were upregulated and SA-related genes were downregulated in GhWRKY70-silenced cotton plants. Overexpression of GhWRKY70 reduced tolerance to V. dahliae in Arabidopsis thaliana. Transgenic Arabidopsis plants showed increased expression of SA-associated genes and reduced expression of JA response-associated genes. These results suggest that GhWRKY70 negatively regulates tolerance to V. dahliae in at least two ways: (ⅰ) by upregulating the expression of SA-associated genes and (ⅱ) by reducing the expression of JA-associated genes. | Xianpeng Xiong Shichao Sun Yanjun Li Xinyu Zhang Jie Sun Fei Xue | 2019 | The Crop Journal2019,7,3: | 5 |
| 8 | Corrosion Behavior about Tubing Steel in Environment with High H_2S and CO_2 Content显示文摘The corrosion behavior of C100 steel in simulated environments with high H2S and CO2 content was studied through high-temperature and high-pressure autoclave,and the H2S stress corrosion cracking(SSC) resistance of C100 steel was evaluated by SSC tests.Scanning electron microscopy(SEM),transmission electron microscope(TEM) and X-ray diffraction(XRD) technique were employed to characterize the corrosion products and the metal matrix.The results indicate that all of the corrosion products in this investigation are mainly composed of different types of iron sulfide such as Fe 0.95 S,FeS 0.9,Fe 0.985 S,Fe7S8 and FeS,and the absence of iron carbonate in the corrosion scales suggests that the corrosion process is governed by H2S corrosion.The corrosion rate decreases in the initial stage and then increases with the enhancement of the temperature.There exists a minimum corrosion rate at about 110 ℃.Under the partial pressure of H2S lower than 9 MPa,the corrosion rate decreases with the increase of.While over 9 MPa,a higher will result in a faster corrosion process.When the applied stress is 72%,80% and 85% of actual yield strength(AYS),all tested specimens show no crack,which reveals a superior SSC resistance. | 李文飞 ZHOU Yanjun XUE Yan | 2013 | Journal of Wuhan University of Technology(Materials Science)2013,28,5: | 5 |
| 9 | Synthesis of Mg-Al-carbonate layered double hydroxide by an atom-economic reaction显示文摘A clean method for preparing layered double hydroxides (LDHs) has been developed, featured by using the hydroxides of two different metals as starting materials by atom-economic reactions. The reactions were carried out under hydrothermal conditions in either a high pressure autoclave or a microwave digester. The compositions, structural parameters and thermal behavior of the resulting LDHs are very similar to those of materials produced by using the separate nucleation and aging steps (SNAS) method. The major advantage of the new method is that no by-product is produced, so that filtration and washing processes are unnecessary. The consequent reduction in water consumption is beneficial to the environment. | Xiangyu Xu Dianqing Li Jiaqing Song Yanjun Lin Zhi Lv Min Wei Xue Duan | 2010 | Particuology2010,8,3: | 4 |
| 10 | Photocatalytic H2 Evolution on TiO2 Assembled with Ti3C2 MXene and Metallic 1T-WS2 as Co-catalysts显示文摘The biggest challenging issue in photocatalysis is efficient separation of the photoinduced carriers and the aggregation of photoexcited electrons on photocatalyst’s surface.In this paper,we report that double metallic co-catalysts Ti3C2 MXene and metallic octahedral(1T)phase tungsten disulfide(WS2)act pathways transferring photoexcited electrons in assisting the photocatalytic H2 evolution.TiO2 nanosheets were in situ grown on highly conductive Ti3C2 MXenes and 1T-WS2 nanoparticles were then uniformly distributed on TiO2@Ti3C2 composite.Thus,a distinctive 1T-WS2@TiO2@Ti3C2 composite with double metallic co-catalysts was achieved,and the content of 1T phase reaches 73%.The photocatalytic H2 evolution performance of 1T-WS2@TiO2@Ti3C2 composite with an optimized 15 wt%WS2 ratio is nearly 50 times higher than that of TiO2 nanosheets because of conductive Ti3C2 MXene and 1T-WS2 resulting in the increase of electron transfer efficiency.Besides,the 1T-WS2 on the surface of TiO2@Ti3C2 composite enhances the Brunauer–Emmett–Teller surface area and boosts the density of active site. | Yujie Li Lei Ding Shujun Yin Zhangqian Liang Yanjun Xue Xinzhen Wang Hongzhi Cui Jian Tian | 2020 | Nano-Micro Letters2020,12,1: | 4 |
| 11 | Searching for the Nano-Hertz Stochastic Gravitational Wave Background with the Chinese Pulsar Timing Array Data ReleaseⅠ显示文摘Observing and timing a group of millisecond pulsars with high rotational stability enables the direct detection of gravitational waves(GWs).The GW signals can be identified from the spatial correlations encoded in the times-of-arrival of widely spaced pulsar-pairs.The Chinese Pulsar Timing Array(CPTA)is a collaboration aiming at the direct GW detection with observations carried out using Chinese radio telescopes.This short article serves as a“table of contents”for a forthcoming series of papers related to the CPTA Data Release 1(CPTA DR1)which uses observations from the Five-hundred-meter Aperture Spherical radio Telescope.Here,after summarizing the time span and accuracy of CPTA DR1,we report the key results of our statistical inference finding a correlated signal with amplitude logA_(c)=-14.4_(-2.8)^(+1.0)for spectral index in the range ofα∈[-1.8,1.5]assuming a GW background(GWB)induced quadrupolar correlation.The search for the Hellings–Downs(HD)correlation curve is also presented,where some evidence for the HD correlation has been found that a 4.6σstatistical significance is achieved using the discrete frequency method around the frequency of 14 n Hz.We expect that the future International Pulsar Timing Array data analysis and the next CPTA data release will be more sensitive to the n Hz GWB,which could verify the current results. | Heng Xu Siyuan Chen Yanjun Guo Jinchen Jiang Bojun Wang Jiangwei Xu Zihan Xue RNicolas Caballero Jianping Yuan Yonghua Xu Jingbo Wang Longfei Hao Jingtao Luo Kejia Lee Jinlin Han Peng Jiang Zhiqiang Shen Min Wang Na Wang Renxin Xu Xiangping Wu Richard Manchester Lei Qian Xin Guan Menglin Huang Chun Sun Yan Zhu | 2023 | Research in Astronomy and Astrophysics2023,23,7: | 3 |
| 12 | Synthesis of porous few-layer carbon nitride with excellent photocatalytic nitrogen fixation显示文摘The porous few-layer g-C_(3)N_(4)(PFL-g-C_(3)N_(4))is prepared by a simple molecular self-assembly method.Compared with pure g-C_(3)N_(4),the as-prepared PFL-g-C_(3)N_(4) is ultrathin,the surface is rich in pores,and the photocatalytic nitrogen fixation activity is greatly increased to 8.20 mM h^(-1) gCat^(-1).Few-layer and ultrathin nature of PFL-g-C_(3)N_(4) can provide a larger specific surface area,expose more active sites,and reduce the diffusion path of charges and protons from the inside to the surface.In addition,the porous structure can narrow the band gap,thereby increasing the light absorption range and enhancing the light absorption capability.Meanwhile,the presence of nitrogen vacancies causes PFL-g-C_(3)N_(4) to move to a more negative conductive band value.More importantly,the isotopic experiments using ^(15)N_(2) as nitrogen source confirm the ammonia production originating from N2 rather than the decomposition of g-C_(3)N_(4).Therefore,PFL-g-C_(3)N_(4) can greatly improve the efficiency of visible light photocatalytic nitrogen fixation. | Yanjun Xue Xiangkun Kong Yichen Guo Zhangqian Liang Hongzhi Cui Jian Tian | 2020 | Journal of Materiomics2020,6,1: | 3 |
| 13 | The development road of ammonium phosphate fertilizer in China显示文摘Ammonium phosphate fertilizer is the compounds containing nitrogen and phosphorus that are usually produced through the neutralization reaction of phosphoric acid and ammonia.At present,there are a variety of products,such as slurry monoammonium phosphate(MAP),diammonium phosphate(DAP),industrial grade MAP,water soluble MAP,water soluble ammonium polyphosphate(APP)and so on.After more than 60 years of development,China’s ammonium phosphate fertilizer industry has experienced the road of from scratch and from weak to strong.The successful development of the slurry MAP technology ended the history that the high concentration phosphate fertilizer cannot be produced by using the medium and low grade phosphate ore.The continuous,stable and large-scale production of DAP plant provides sufficient guarantee for DAP products in China.The development of new ammonium phosphate fertilizer products,such as industrial grade MAP,water soluble MAP,water soluble APP,provides technical support for the transformation and upgrading of phosphorus chemical enterprises.In this paper,the production methods,the development history and the latest research progress of ammonium phosphate fertilizers were reviewed. | Dehua Xu Benhe Zhong Xinlong Wang Xue Li Yanjun Zhong Zhengjuan Yan Jingxu Yang Xiaobin Li Yumei Wang Xiaohou Zhou | 2022 | Chinese Journal of Chemical Engineering2022,35,1: | 3 |
| 14 | Smoke suppressant in flame retarded thermoplastic polyurethane composites: Synergistic effect and mechanism study显示文摘Considerable smoke and toxic volatiles generation has compromised the application of thermoplastic polyurethane (TPU) and caused a great threat to human life. Here, nano-MgFe layered double hydroxide (MgFe-LDH) with uniform particle size was synthesized to reduce smoke density and toxic gases of TPU composites using ammonium polyphosphate (APP) as a flame retardant agent. The results show that the combination of 16 wt.% APP and 4 wt.% MgFe-LDH greatly decreased the smoke density (D20min and Ds, max), smoke production rate (SPR) and heat release rate (HRR) of TPU composites. Furthermore, the MgFe-LDH synergist demonstrated high efficiency in decreasing total volatiled products and toxic volatiles evolved, such as the CO, HCN and isocyanates. The reason was mainly attributed to the chemical reaction between MgFe-LDH and APP, which can promote the compactness of char layers with fine microstructure formed in the decomposition process of MgFe-LDH/APP/TPU composites. The protective char layers could act as barriers between combustion zone and matrix to protect the unburned substrate and promote smoke suppression effect. | Hongyuan Ren Kelan Qing Ying Chen Yanjun Lin Xue Duan | 2021 | Nano Research2021,14,11: | 2 |
| 15 | HvWRKY2 acts as an immunity suppressor and targets HvCEBiP to regulate powdery mildew resistance in barley显示文摘Plants use a sophisticated immune system to perceive pathogen infection and activate immune responses in a tightly controlled manner.In barley,Hv WRKY2 acts as a repressor in barley disease resistance to the powdery mildew fungus,Blumeria graminis f.sp.hordei(Bgh).However,the molecular features of Hv WRKY2 in its DNA-binding and repressor functions,as well as its target genes,are uncharacterized.We show that the W-box binding of Hv WRKY2 requires an intact WRKY domain and an upstream sequence of~75 amino acids,and the Hv WRKY2 W-box binding activity is linked to its repressor function in disease resistance.Chromatin immunoprecipitation(ChIP)-seq analysis identified HvCEBiP,a putative chitin receptor gene,as a target gene of Hv WRKY2 in overexpressing transgenic barley plants.ChIP-qPCR and Electrophoretic Mobility Shift Assay(EMSA)verified the direct binding of Hv WRKY2 to a W-boxcontaining sequence in the HvCEBiP promoter.Hv CEBiP positively regulates resistance against Bgh in barley.Our findings suggest that Hv WRKY2 represses barley basal immunity by directly targeting pathogen-associated molecular pattern(PAMP)recognition receptor genes,suggesting that Hv CEBiP and likely chitin signaling function in barley PAMP-triggered immune responses to Bgh infection. | Deshui Yu Renchun Fan Ling Zhang Pengya Xue Libing Liao Meizhen Hu Yanjun Cheng Jine Li Ting Qi Shaojuan Jing Qiuyun Wang Arvind Bhatt Qian-Hua Shen | 2023 | The Crop Journal2023,11,1: | 1 |

| 17 | The metallic 1T-WS_(2)as cocatalysts for promoting photocatalytic N_(2) fixation performance of Bi_(5)O_(7)Br nanosheets显示文摘Recently,widespread attention has been devoted to the typical layered BiOCl or BiOBr because of the suitable nanostructure and band structure.However,owing to the fast carrier recombination,the photocatalytic performance of BiOX materials is not so satisfactory.Loading 1T phase WS_(2)nanosheets(NSs)onto Bi_(5)O_(7)Br NSs can improve the photocatalytic N_(2)fixation activity.Among these,the obtained 1T-WS_(2)@Bi_(5)O_(7)Br composites with optimum 5%1T-WS_(2)NSs display a significantly improved photocatalytic N_(2)fixation rate(8.43 mmol L^(−1)h^(−1)g^(−1)),2.51 times higher than pure Bi_(5)O_(7)Br(3.36 mmol L^(−1)h^(−1)g^(−1)).And the outstanding stability of 1T-WS_(2)@Bi_(5)O_(7)Br-5 composites is also achieved.Exactly,the photoexcited electrons from Bi_(5)O_(7)Br NSs are quickly transferred to conductive 1T phase WS_(2)as electron acceptors,which can promote the separation of carriers.In addition,1T-WS_(2)NSs can provide abundant active sites on the basal and edge planes,which can promote the efficiency of photocatalytic N_(2)fixation.This work offers a novel solution to improve the photocatalytic performance of Bi_(5)O_(7)Br NSs. | Pengyuan Qiu Jianwei Wang Zhangqian Liang Yanjun Xue Yanli Zhou Xiaoli Zhang Hongzhi Cui Guiqing Cheng Jian Tian | 2021 | Chinese Chemical Letters2021,32,11: | 1 |

| 20 | Visible light assisted enzyme-photocatalytic cascade degradation of organophosphorus pesticides显示文摘The worldwide application of organophosphorus pesticides(OPs)has promoted agricultural development,but their gradual accumulation in soil and water can seriously affect the central nervous system of humans and other mammals.Organophosphorus hydrolase(OPH)is an effective enzyme that can catalyze the degradation of the residual OPs.However,the degradation products such as p-nitrophenol(p-NP)is still toxic.Thus,it is of great significance to develop a multi-functional support that can be simultaneously used for the immobilization of OPH and the further degradation of p-NP.Herein,a visible light assisted enzyme-photocatalytic integrated catalyst was constructed by immobilizing OPH on hollow structured Au-TiO_(2)(named OPH@H-Au-TiO_(2))for the degradation of OPs.The obtained OPH@H-Au-TiO_(2)can degrade methyl parathion to p-NP by OPH and then degrade p-NP to hydroquinone with low toxicity by using H-Au-TiO_(2)under visible light.OPH molecules were immobilized on HAu-TiO_(2)through adsorption method to prepare OPH@H-Au-TiO_(2).After 2.5 h of reaction,methyl parathion is completely degraded,and about 82.64%of the generated p-NP is further degraded into hydroquinone.After reused for 4 times,the OPH@H-Au-TiO_(2)retains more than 80%of the initial degradation activity.This research presents a new insight in designing and constructing multi-functional biocatalyst,which greatly expands the application scenarios and industrial value of enzyme catalysis. | Ying Zhang Xue Cao Yufeng Yang Sumin Guan Xiaotian Wang Heyu Li Xiaobing Zheng Liya Zhou Yanjun Jiang Jing Gao | 2023 | Green Chemical Engineering2023,4,1: | 1 |
