| 1 | Full-Sized Pore Structure and Fractal Characteristics of Marine-Continental Transitional Shale: A Case Study in Qinshui Basin, North China显示文摘Based on 10 shale samples collected from 4 wells in Qinshui Basin,we investigate the full-sized pore structure and fractal characteristics of Marine-Continental transitional shale by performing organic geochemistry,mineralogical composition,Nitrogen gas adsorption(N2 adsorption)and Nuclear Magnetic Resonance(NMR)measurements and fractal analysis.Results show that the TOC content of the shale samples is relatively high,with an average value of 2.44wt%,and the thermal evolution is during the mature-over mature stage.The NMR T2 spectrum can be used to characterize the fullsized pore structure characteristics of shale.By combining N2 adsorption pore structure parameters and NMR T2 spectrums,the surface relaxivity of samples are calculated to be between 1.7877 um/s and 5.2272 um/s.On this basis,the T2 spectrums are converted to full-sized pore volume and surface area distribution curves.The statistics show that the pore volume is mainly provided by mesopore,followed by micropore,and the average percentages are 65.04%and 30.83%respectively;the surface area is mainly provided by micropore,followed by mesopore,and the average percentages are 60.8004%and 39.137%respectively;macropore contributes little to pore volume and surface area.The pore structure characteristics of shale have no relationship with TOC,but strong relationships with clay minerals content.NMR fractal dimensions Dmicro and Dmeso have strong positive relationships with the N2 adsorption fractal dimensions D1 and D2 respectively,indicating that Dmicro can be used to characterize the fractal characteristics of pore surface,and Dmeso can be used to characterize the fractal characteristics of pore structure.The shale surface relaxivity is controlled by multiple factors.The increasing of clay mineral content,pore surface area,pore surface fractal dimension and the decreasing of average pore size,will all lead to the decreasing of shale surface relaxivity. | YIN Liangliang GUO Shaobin | 2019 | Acta Geologica Sinica(English Edition)2019,93,3: | 5 |

| 3 | Interference at the single-photon level based on silica photonics robust against channel disturbance显示文摘Quantum key distribution(QKD) provides a solution for communication of unconditional security. However,the quantum channel disturbance in the field severely increases the quantum bit-error rate, degrading the performance of a QKD system. Here we present a setup comprising silica planar light wave circuits(PLCs), which is robust against the channel polarization disturbance. Our PLCs are based on the asymmetric Mach–Zehnder interferometer(AMZI), integrated with a tunable power splitter and thermo-optic phase modulators. The polarization characteristics of the AMZI PLC are investigated by a novel pulse self-interfering method to determine the operation temperature of implementing polarization insensitivity. Over a 20 km fiber channel with 30 Hz polarization scrambling, our time-bin phase-encoding QKD setup is characterized with an interference fringe visibility of 98.72%. The extinction ratio for the phase states is kept between 18 and 21 d B for 6 h without active phase correction. | XIAO LI MEIZHEN REN JIASHUN ZHANG LIANGLIANG WANG WEI CHEN YUE WANG XIAOJIE YIN YUANDA WU JUNMING AN | 2021 | Photonics Research2021,9,2: | 2 |
| 4 | Monitoring fire regimes and assessing their driving factors in Central Asia显示文摘Relatively little is known about fire regimes in grassland and cropland in Central Asia.In this study,eleven variables of fire regimes were measured from 2001 to 2019 by utilizing the burned area and active fire product,which was obtained and processed from the GEE(Google Earth Engine)platform,to describe the incidence,inter-annual variability,peak month and size of fire in four land cover types(forest,grassland,cropland and bare land).Then all variables were clustered to define clusters of fire regimes with unique fire attributes using the K-means algorithm.Results showed that Kazakhstan(KAZ)was the most affected by fire in Central Asia.Fire regimes in cropland in KAZ had the frequent,large and intense characters,which covered large burned areas and had a long duration.Fires in grassland mainly occurred in central KAZ and had the small scale and high-intensity characters with different quarterly frequencies.Fires in forest were mainly distributed in northern KAZ and eastern KAZ.Although fires in grassland underwent a shift from more to less frequent from 2001 to 2019 in Central Asia,vigilance is needed because most fires in grassland occur suddenly and cause harm to humans and livestock. | YIN Hanmin Jiapaer GULI JIANG Liangliang YU Tao Jeanine UMUHOZA LI Xu | 2021 | Journal of Arid Land2021,13,5: | 1 |

| 7 | SNX17 regulates Notch pathway and pancreas development through the retromer-dependent recycling of Jag1显示文摘Background:Notch is one of the most important signaling pathways involved in cell fate determination.Activation of the Notch pathway requires the binding of a membrane-bound ligand to the Notch receptor in the adjacent cell which induces proteolytic cleavages and the activation of the receptor.A unique feature of the Notch signaling is that processes such as modification,endocytosis or recycling of the ligand have been reported to play critical roles during Notch signaling,however,the underlying molecular mechanism appears context-dependent and often controversial.Results:Here we identified SNX17 as a novel regulator of the Notch pathway.SNX17 is a sorting nexin family protein implicated in vesicular trafficking and we find it is specifically required in the ligand-expressing cells for Notch signaling.Mechanistically,SNX17 regulates the protein level of Jag1a on plasma membrane by binding to Jag1a and facilitating the retromer-dependent recycling of the ligand.In zebrafish,inhibition of this SNX17-mediated Notch signaling pathway results in defects in neurogenesis as well as pancreas development.Conclusions:Our results reveal that SNX17,by acting as a cargo-specific adaptor,promotes the retromer dependent recycling of Jag1a and Notch signaling and this pathway is involved in cell fate determination during zebrafish neurogenesis and pancreas development. | Wenguang Yin Dapeng Liu Nian Liu Liangliang Xu Song Li Shuo Lin Xiaodong Shu Duanqing Pei | 2012 | Cell Regeneration2012,1,1: | 1 |
| 8 | Geology,Mineralogy,and Isotopic Characteristics of the Zhonghe Ag-Pb-Zn Deposit,Western Henan Province,Central China显示文摘Located in Luoning County,western Henan Province,Central China,the Zhonghe Ag-Pb-Zn ore field,is a newly discovered deposit in the Xiaoshan District.Ore bodies controlled by NNW Faults occur as veins within the Paleoproterozoic Xiong’er Group or the Early Cretaceous porphyritic granite.Given that the Zhonghe deposit has been covered by thick Quaternary sediments,the paragenetic mineral assemblage was determined mainly by microscopic observations,including the quartzsiderite-pyrite alteration (StageⅠ),polymetallic sulfide precipitation (StageⅡ),silver mineralization(Stage Ⅲ),and quartz-carbonate stage (StageⅣ).The host minerals for silver are diverse,such as freibergite,pyrargyrite,polybasite,argyrodite,canfieldite,argentite,and native silver,whereas those for Pb and Zn are galena and sphalerite,respectively.In order to constrain the ore-forming components of the Zhonghe deposit,a combined in-situ analysis was conducted on represented sulfides from StageⅡand Stage Ⅲ.In-situ δ^(34)S values of the analyzed sulfides,including the pyrite,chalcopyrite,sphalerite,and galena,display a relatively narrow range (0.90‰-5.0‰),which is close to magmatic sulfur source.The ^(206)Pb/^(204)Pb and^(207)Pb/^(204)Pb ratios show a narrow range (17.140-17.360 and 15.385-15.490),whereas the ^(208)Pb/^(204)Pb ratios exhibit a broad variation (36.601-37.943),indicating a contamination of the Xiong’er Group.Synthesis of geochronological and geochemical data from the Xiaoshan District,we contend that the ore-forming materials of the Zhonghe Ag-Pb-Zn deposit are originated from the lower crust,which has presumably been influenced by the large-scale lithospheric delamination of the eastern North China Craton during the Early Cretaceous.In consideration of the geological setting,mineralogy,and geochemical compositions,we suggest that the Zhonghe Ag-Pb-Zn deposit is characterized as intermediate sulfidation type epithermal deposit,and may be a potential exploration target for porphyry Mo-Cu deposits. | Jiannan Xu Changqian Ma Shuo Yin Yunzhen Chang Huimin Jia Zhongjie Wang Liangliang Shi | 2022 | Journal of Earth Science2022,33,1: | 1 |

| 10 | Extracellular polymeric substances-antibiotics interaction in activated sludge:A review显示文摘Antibiotics,the most frequently prescribed drugs,have been widely applied to prevent or cure human and veterinary diseases and have undoubtedly led to massive releases into sewer networks and wastewater treatment systems,a hotspot where the occurrence and transformation of antibiotic resistance take place.Extracellular polymeric substances(EPS),biopolymers secreted via microbial activity,play an important role in cell adhesion,nutrient retention,and toxicity resistance.However,the potential roles of sludge EPS related to the resistance and removal of antibiotics are still unclear.This work summarizes the composition and physicochemical characteristics of state-of-the-art microbial EPS,highlights the critical role of EPS in antibiotics removal,evaluates their defense performances under different antibiotics exposures,and analyzes the typical factors that could affect the sorption and biotransformation behavior of antibiotics.Next,interactions between microbial EPS and antibiotic resistance genes are analyzed.Future perspectives,especially the engineering application of microbial EPS for antibiotics toxicity detection and defense,are also emphatically stressed. | Weixin Zhao Jia You Shilei Yin Haizhou Yang Shufei He Likui Feng Jianju Li Qingliang Zhao Liangliang Wei | 2023 | Environmental Science and Ecotechnology2023,,1: | 0 |
| 11 | Two types of coumarins-specific enzymes complete the last missing steps in pyran- and furanocoumarins biosynthesis显示文摘Pyran-and furanocoumarins are key representatives of tetrahydropyrans and tetrahydrofurans,respectively,exhibiting diverse physiological and medical bioactivities.However,the biosynthetic mechanisms for their core structures remain poorly understood.Here we combined multiomics analyses of biosynthetic enzymes in Peucedanum praeruptorum and in vitro functional verification and identified two types of key enzymes critical for pyran and furan ring biosynthesis in plants.These included three distinct P.praeruptorum prenyltransferases(PpPT1e3)responsible for the prenylation of the simple coumarin skeleton 7 into linear or angular precursors,and two novel CYP450 cyclases(PpDC and PpOC)crucial for the cyclization of the linear/angular precursors into either tetrahydropyran or tetrahydrofuran scaffolds.Biochemical analyses of cyclases indicated that acid/base-assisted epoxide ring opening contributed to the enzyme-catalyzed tetrahydropyran and tetrahydrofuran ring refactoring.The possible acid/base-assisted catalytic mechanisms of the identified cyclases were theoretically investigated and assessed using site-specific mutagenesis.We identified two possible acidic amino acids Glu303 in PpDC and Asp301 in PpOC as vital in the catalytic process.This study provides new enzymatic tools in the epoxide formation/epoxide-opening mediated cascade reaction and exemplifies how plants become chemically diverse in terms of enzyme function and catalytic process. | Yucheng Zhao Yuedong He Liangliang Han Libo Zhang Yuanzheng Xia Fucheng Yin Xiaobing Wang Deqing Zhao Sheng Xu Fei Qiao Yibei Xiao Lingyi Kong | 2024 | Acta Pharmaceutica Sinica B2024,14,2: | 0 |
| 12 | Enhancement of morphological and emission stability of deep-blue small molecular emitter via a universal side-chain coupling strategy for optoelectronic device显示文摘Film morphology of emissive layers is crucial to the performance and stability of solution-processable organic light-emitting diodes(OLEDs). Compared to the interpenetration of conjugated polymer chain,small molecular emitter with a flexible side chain always presents easily aggregation upon external treatment, and caused π-electronic coupling, which is undesirable for the efficiency and stability of deep-blue OLEDs. Herein, we proposed a side-chain coupling strategy to enhance the film morphological an emission stability of solution-processable small molecular deep-blue emitter. In contrary to “parent” MC8 TPA,the crosslinkable styryl and vinyl units were introduced as ended unit at the side-chain of Cm TPA and OEYTPA. Interestingly, Cm TPA and OEYTPA films present a relatively stable morphology and uniform deep-blue emission after thermal annealing(160 ℃) in the atmosphere, different to the discontinuous MC8 TPA annealed film. Besides, compared to the Cm TPA and OEYTPA ones, serious polaron formation in the MC8 TPA annealed film also negative to the deep-blue emission, according to transient absorption analysis. Therefore, both Cm TPA and OEYTPA annealed film obtained at 140 ℃ present an excellent deep-blue ASE behavior with a 445 nm, but absence for MC8 TPA ones, associated with the disruption of annealed films. Finally, enhancement of device performance based on Cm TPA and OEYTPA film(~40%)after thermal annealing with a similar performance curves also confirmed the assumption above. Therefore, these results also supported the effectiveness of our side-chain coupling strategy for optoelectronic applications. | Ning Sun Han Gao Lili Sun Jingxi An Man Xu Chen Sun Yamin Han Jinyi Lin Jiangli Cai Mingjian Ni Liangliang He Jinghao Yang Zhoulu Wang Lubing Bai Xinwen Zhang Qi Wei Xuehua Ding Chengrong Yin Linghai Xie Wei Huang | 2022 | Chinese Chemical Letters2022,33,2: | 0 |
| 13 | Mn-mediated reductive C(sp3)–Si coupling of activated secondary alkyl bromides with chlorosilanes显示文摘The construction of secondary alkylsilanes is a challenging subject in the synthetic community.The cross-coupling provides a practical solution to address this problem,but it typically relies on organometallic species.Herein,we report an Mn-mediated reductive C(sp^(3))-Si coupling to synthesize these compounds from alkyl and silyl electrophiles.This approach avoids the requirement for activation of Si-Cl by transition metals and thus allows for the coupling of various common chlorosilanes.The reaction proceeds under mild conditions and shows good functional group compatibility.The method offers access toα-silylated organophosphorus and sulfones with a scope that is complementary to those obtained from the established methods. | Liangliang Qi Xiaobo Pang Kai Yin Qiu-Quan Pan Xiao-Xue Wei Xing-Zhong Shu | 2022 | Chinese Chemical Letters2022,33,12: | 0 |
| 14 | Determination of thorium in the hair and urine of workers and the public in a rare earth mining area显示文摘Objective:To assess the thorium exposure of the mine workers and the public to a typical rare earth mine and estimate the resultant committed effective dose to them.Methods:A total of 79 volunteers were selected in this survey,including 69 mine workers and 10 local residents living about 4 km away from the mine site.Urinary samples were collected from 79 volunteers,with 65 hair samples from 57 workers and 8 local residents.The thorium concentrations in urinary and hair samples were determined by using inductively coupled plasma mass spectrometry.The committed effective doses were estimated based on the urinary samples collected and the parameters as recommended by ICRP Publication 137.Results:Thorium concentrations in the samples from the workers ranged from 19.0 to 2388.8 ng/g in hair with median of 149.8 ng/g,and in urine 18.3–906.1 ng/L with median of 59.6 ng/L,respectively.The median values of thorium concentrations were 11.8 ng/g in hair and 32.40 ng/L in urine for the public respectively.The thorium concentrations in urinary and hair samples of the workers were not only higher than those of the residents in the local area,but also than those of non-occupationally exposed populations as reported.The median values of committed effective dose were estimated to be 1.51 mSv for the workers and 781μSv for the local residents,respectively.Conclusions:The residents in the local area,and especially the workers,have been subject to long term thorium exposure.More attention should be paid to the radiological hazards of thorium to the workers and local residents. | Yao Zhang Xianzhang Shao Xiangyin Kong Liangliang Yin Chengguo Wang Liang Lin Yanqin Ji | 2022 | Radiation Medicine and Protection2022,3,2: | 0 |
| 15 | Coupled autotransformer and magneticcontrol soft-start method for super-largecapacity high-voltage motors显示文摘The large current generated by a direct start of the super-large-capacity high-voltage induction motor would have a huge impact on the power grid as well as the motor itself.Traditional soft starters have the shortcomings of discontinuous adjustment,voltage sags,sudden torque mutation,secondary current impact and high cost.To resolve this issue,the authors propose a novel coupled autotransformer and magnetic-control(CATMC)soft-start method.The structure of the new CATMC soft starter combines the functions of the autotransformer and magnetic control reactor via an innovative electric and magnetic circuit design.In this study,the authors analyse the magnetic circuit structure and working principles of the CATMC soft starter.Then,to validate its principle and performance,the authors conduct a simulation study using ANSYS software and design and test an 18 MW/10 kV CATMC soft starter prototype.The simulation results demonstrate that the CATMC soft starter effectively avoids secondary current impact and constrains the motor starting current to<2.5 times the rated current.The public connection point bus voltage also meets the voltage sag requirement of the IEEE standard and reduces the impact on the power grid. | Jiaxin Yuan Chuansheng Wang Shan Yin Liangliang Wei Kazuhiro Muramatsu Baichao Chen | 2020 | High Voltage2020,5,1: | 0 |
