| 1 | Mesozoic contraction deformation in the Yanshan and northern Taihang mountains and its implications to the destruction of the North China Craton显示文摘Mesozoic contraction deformation in the Yanshan and Taihang mountains is characterized by basement-involved thrust tectonics,basement-cored buckling anticlines and ductile thrust and nappe tectonics.Most of these deformations are orientated west-east,west-northwest and northeast to north-northeast.The contraction deformations began in the Permian,continued through the Triassic and Jurassic and terminated in the Early Cretaceous,and constitute an important part of the destruction of the North China Craton.It is estimated,from balanced cross-section reconstructions,that the north-south shortening of the central part of the Yanshan belt before 135 Ma was around 38%.The initial crust thickness,pre-dating the major contraction deformation in late Paleozoic and early Mesozoic,was estimated to be around 35 km based on paleogeographic characteristics.Assuming that the inferred depth of ductile thrusting deformation,20-25 km,was the crust thickness involved in the contraction deformation,and also assuming that the N-S contraction deformation was accommodated by vertical crust thickening,the thickness of the crust after the contraction deformation was expected to be around 47-50 km.This was the approximate crust thickness required for the eclogitization of the lower crust for delamination.The gravity potential accumulated by the isostatic uplift of the thickened crust,together with the decrease in crustal strength caused by the coeval magmatisms associated with the contraction deformation,led to the subsequent extensional collapse of the middle and upper crust although the regional stress regime associated with the plate interactions remained constant.It is inferred that the Mesozoic contraction deformations in the Yanshan and Taihang mountains were not only a significant tectonic process contributing to the destruction of the craton in middle and upper crust but also stimulated delamination at a deep level and the extension of the shallow crust.In other words,both the suspected delamination of the lower crust and upper mantle and the well constrained extension deformations of the shallow crust in the eastern North China Craton during the late Mesozoic are a consequence of crust thickening due to previous contractions.Extensional deformations could be expected to occur independently in the shallow crust,and are not necessarily associated with or responding to delamination at a deep level. | ZHANG ChangHou LI ChengMing DENG HongLing LIU Yang LIU Lei WEI Bo LI HanBin LIU Zi | 2011 | Science China Earth Sciences2011,54,6: | 40 |
| 2 | Strength and Stability Analysis of Deep Sea Drilling Risers显示文摘In order to analyze the influence of vortex-induced vibration on the strength and stability of marine drilling risers, a simplified analytical model was established and a method for calculating vortex-induced dynamic response was developed. A case study indicated that at primary resonance, first-order dynamic displacement response is greater than higher-order mode responses, but the influence of dynamic moment and shearing force of higher-order modes cannot be ignored. The natural frequency of risers decreased sharply with increasing length of the riser, but increased with increasing top tension. Various factors should be considered to avoid vortex-induced vibration in practical application, and the influence of vortex-induced vibration could be estimated by calculating the fatigue lifetime of riser. | Yang Jin Liu Caihong Liu Hanbin Xie Renjun Cao Shijing | 2007 | Petroleum Science2007,4,2: | 5 |
| 3 | Shugan Huoxue Huayu Fang(疏肝活血化瘀方)attenuates carbon tetrachloride-induced hepatic fibrosis in rats by inhibiting transforming growth factor-β1/Smad signaling显示文摘OBJECTIVE:To investigate the potential mechanism by which Shugan Huoxue Huayu Fang(疏肝活血化瘀方,SGHXHYF)ameliorates liver fibrosis.METHODS:Liver fibrosis was induced in rats by intraperitoneal injection of carbon tetrachloride(CCl_(4))in peanut oil solution(40%,3 m L/kg body weight)twice a week for 8 weeks.A normal control group received the same volume of peanut oil alone.During weeks 5-8,the CCl_(4)-injected rat groups were administered saline(vehicle control),colchicine(0.1 mg/mL,1 mg/kg,positive control),or SGHXHYF(0.1 mg/mL;0.3,0.6 and 1.2 mg/kg)once daily by oral gavage.Rats were sacrificed 24 h after the last treatment.Blood samples were collected for measurement of serum alanine aminotransferase(ALT),aspartate aminotransferase(AST),alkaline phosphatase(ALP),albumin(ALB),collagenⅠ,and collagenⅢlevels.Liver samples were analyzed by histopathological staining,Masson's staining of extracellular matrix proteins,and immune-ohistochemical staining ofα-smooth muscle actin(α-SMA).TGF-β1/Smad protein and mRNA levels were analyzed by Western blot and quantitative reverse transcription-polymerase chain reaction analysis,respectively.In vitro experiments were also performed using rat hepatic stellate cells(HSCs).RESULTS:Compared with the control animals,CCl_(4)-exposed rats exhibited elevated serum levels of ALT,AST,ALP,collagenⅠ,and collagenⅢ;reduced serum levels of ALB;and increased collagen deposition andα-SMA expression in liver sections,reflecting liver fibrosis.CCl_(4) also increased expression of TGF-β1 and the activated(phosphorylated)forms of Smad2 and Smad3 but reduced expression of the negative regulator Smad7 in the liver.Notably,concomitant administration of SGHXHYF to CCl_(4)-exposed rats was found to significantly reverse or abolish the pro-fibrotic effects of CCl_(4) in the liver and reduced serum transferase levels.Analysis of HSCs in vitro confirmed that,mechanistically,SGHXHYF inhibited activation of the TGF-β1/Smad signaling pathway by downregulating phosphorylated Smad2 and Smad3 and upregulating Smad7 levels.CONCLUSION:SGHXHYF ameliorated CCl_(4)-induced liver fibrosis by inhibiting the TGF-β1/Smad signaling pathway.These findings suggest that SGHXHYF may have clinical utility for the treatment or prevention of liver fibrosis. | LIU Lei GUO Hanbin SHAO Cuiping WANG Lin XU Youqing ZHOU Yiming | 2022 | Journal of Traditional Chinese Medicine2022,42,1: | 2 |
| 4 | Green flexible electronics based on starch显示文摘Flexible electronics(FEs)with excellent flexibility or foldability may find widespread applications in the wearable devices,artificial intelligence(AI),Internet of Things(IoT),and other areas.However,the widely utilization may also bring the concerning for the fast accumulation of electronic waste.Green FEs with good degradability might supply a way to overcome this problem.Starch,as one of the most abundant natural polymers,has been exhibiting great potentials in the development of environmental-friendly FEs due to its inexpensiveness,good processability,and biodegradability.Lots of remarks were made this field but no summary was found.In this review,we discussed the preparation and applications of starch-based FEs,highlighting the role played by the starch in such FEs and the impacts on the properties.Finally,the challenge was discussed and the outlook for the further development was also presented. | Huacui Xiang Zhijian Li Hanbin Liu Tao Chen Hongwei Zhou Wei Huang | 2022 | npj Flexible Electronics2022,6,1: | 1 |

| 9 | MAA-modified and luminescence properties of ZnO quantum dots显示文摘The precursor of ZnO has been prepared by refluxing in ethanol at 70℃ for 4 h using ZnAc2·H2O as the initial agent. Then ZnO has been prepared from the reaction of LiOH·H2O and the precursor. The ZnO is modified by mercaptoacetic acid (MAA) and detected by SEM and XRD. These ZnO particles have single phase,like-sphere and size of 4.6 nm. The modified effectivity of MAA for the quantum dots (QDs) has been investigated with UV-visible and fluorescence analysis,and the mechanism and property of ZnO light emitting have been discussed under given conditions. The reasons why the fluorescent emission peak of surface defects disappear and the exciton emission peak increase are that MAA effectively covers the surface defects of ZnO and stably coats ZnO particles. At the same time,the effect of the added amount of the MAA,temperature and electrolyte on light-emitting properties of modified product has also been studied. The result shows that the modified ZnO QDs have good fluorescence property,stability and suitable capability of resisting electrolyte. These results are important for biological analysis. | ZHUANG Jia LIU Meng LIU HanBin | 2009 | Science China Chemistry2009,52,12: | 1 |
| 10 | Covalently tethering disulfonic acid moieties onto polyoxometalate boosts acid strength and catalytic performance for hydroxyalkylation/alkylation reaction显示文摘Solid acid catalysts are widely used in the production of various high-value added and industrially important chemicals.Although the use of organosilicon compounds to modify the vacancy site has been extensively studied,the covalent tethering-SO_(3)H functionalized organosilicon modified polyoxometalates(POMs)has been rarely reported.In this work,two catalysts(TBA_(4)[SiW_(11)O_(39)(O(SiC_(3)H_(6)SO_(3)H)_(2))](compound 2)and TBA_(4)[SiW_(11)O_(39)(O(SiC_(8)H_(8)SO_(3)H)_(2))](compound 3))were synthesized successfully through covalently grafting different sulfonic acid(-SO_(3)H)groups onto[SiW_(11)O_(39)]^(8−)cluster,respectively.Compound 2 was achieved by surface grafting and in situ oxidation(3-mercaptopropyl)-trimethoxysilane,while compound 3 was achieved by surface grafting of 2-(4-chlorosulfonylphenyl)ethyltrimethoxysilane.Strong Brønsted acid strength of compounds 2 and 3 can be demonstrated by different methods including potentiometric titration,pyridine adsorption studies,and the ^(31)P trimethylphosphine oxides(TMPO)nuclear magnetic resonance(NMR).The systematic investigation of the relationship among POM structures,acid strength,and electron density was carried out based on density functional theory(DFT)calculation and experimental results,which revealed that covalent modification of compounds 2 and 3 decreased the electron density of the O-H bond,and promoted the release of H^(+).When applied in hydroxyalkylation/alkylation(HAA)reaction of 2-methylfuran(2-MF)with cyclohexanone,compound 2 exhibited better catalytic performance with conversion of ~93%,monocyclic fuel precursors(1a)yield of 79.9% and selectivity of 85.7% than compound 3,which can be attributed to strong Brønsted acid and the intramolecular hydrogen-bonding interactions between the neighboring -SO_(3)H moieties in compound 2.Finally,compound 2 also showed excellent catalytic activity in the HAA reaction of 2-MF with several different aldehydes and ketones(e.g.,furfuraldehyde,5-methylfurfuraldehyde,acetone,butyraldehyde and 4-methoxybenzaldehyde).This result opens a new pathway for design and fabrication of novel solid acid catalysts. | Lifei Lian Yubing Liu Xianfeng Yi Hanbin Hu Xiang Chen Hongqiang Li Wei Chen Anming Zheng Yu-Fei Song | 2022 | Science China Chemistry2022,65,4: | 1 |

| 13 | Mid-infrared active metasurface based on Si/VO_(2) hybrid meta-atoms显示文摘Active metasurfaces whose optical properties can be tuned by an external stimulus have attracted great research interest recently. Introduction of VO_(2)phase change material in all-dielectric metasurfaces has been demonstrated to modulate the resonance wavelength and amplitude in the visible to near-infrared wavelength range. In this study, we report a mid-infrared active metasurface based on Si∕VO_(2)hybrid meta-atoms. By incorporating VO_(2)thin films in different locations of Si∕VO_(2)all-dielectric nanodisks, we demonstrate different modulation amplitude of the electric or magnetic resonance scattering cross sections, leading to drastically different transmission spectrum upon VO_(2)insulator to metal phase transition. The physical mechanism is originated from the field profiles of the resonance modes, which interact with VO_(2)differently depending on its locations. Based on this mechanism, we experimentally demonstrated a large modulation of the transmittance from 82% to 28% at the 4.6 μm wavelength. Our work demonstrates a promising potential of VO_(2)-based active all-dielectric metasurface for mid-infrared photonic applications such as infrared camouflage, chemical/biomedical sensing, optical neuromorphic computing, and multispectral imaging. | Tongtong Kang Boyu Fan Jun Qin Weihao Yang Shuang Xia Zheng Peng Bo Liu Sui Peng Xiao Liang Tingting Tang Longjiang Deng Yi Luo Hanbin Wang Qiang Zhou Lei Bi | 2022 | Photonics Research2022,10,2: | 1 |

| 15 | Continuous video electroencephalogram for herpes simplex encephalitis:a case report and literature review显示文摘Background:Electroencephalogram(EEG)is an important tool for the diagnosis of herpes simplex virus encephalitis(HSE).However,the diagnosis of non-convulsive status epilepticus(NCSE)in HSE is challenging without the help of continuous video EEG(CVEEG),and whether EEG is a predictor of outcome remains controversial.Case presentation:A 63-year-old woman presented with a 5 day history of fever,coma and seizures.Results of EEG,magnetic resonance imaging and polymerase chain reaction(PCR)in cerebrospinal fluid(CSF)were suggestive of herpes simplex encephalitis-1(HSE-1).Preliminary EEG showed periodic discharges at the prefrontal and temporal lobes,which were particularly synchronized with intermittent lip smacking movements,and the discharges were terminated by diazepam.After 2-week treatment with acyclovir,high-dose hormone pulse therapy and high-dose immunoglobulin therapy,the CSF was improved,but the patient’s consciousness became worsen,consistent with the diffuse slow waves in the delta range and low voltage of EEG activity.In the following 1 month,the patient had non-responsiveness to pain and sound as shown by CVEEG with diffuse slow waves.Sometimes paroxysmal very slow waves(0.5–1 Hz)were synchronized with intermittent paroxysmal eye movements,pupil abnormality,and sweating in the frontal area.After 2 months of treatment,the EEG abnormalities improved to have alpha rhythm.Conclusion:The CVEEG not only helps identify NCSE but can also be used to monitor HSE progression. | Wanhui Lin Shenggen Chen Hanbin Lin Changyun Liu Huapin Huang | 2020 | Acta Epileptologica2020,2,1: | 0 |
| 16 | Experimental evidence for field-induced metamagnetic transition of EuCd_(2)As_(2)显示文摘Recent studies have shown that layered compound EuCd_(2)As_(2) could exhibit diverse topological states depending on the different magnetic structures,such as Weyl semimetal,Dirac semimetal and topological insulato r.In order to further study the interplay between magnetism and topology of EuCd_(2)As_(2),it is necessary to figure out its magnetic structure.Here,by magnetization(M) measurements and negative magnetostriction(λ) along the [001] direction measured by scanning tunneling microscopy on EuCd_(2)As_(2) single crystals,we observe field-induced metamagnetic phase transition from A-type antiferromagnetic(AFM) ground state to field-polarized state,with canted AFM(CAFM) state in between.Magnetization and magnetostriction are more sensitive to the in-plane field than the out-of-plane field,indicating the magnetic moments lying in the ab plane.The absence of abrupt jump on M-H and λ-H curves demonstrates that the phase transition is a second-order type.In CAFM state,M increases linearly with the field and λ is proportional to M~2.Tunneling conductance spectra show the field-induced evolution of the electronic density of states.Our results provide experimental evidence for understanding the magnetic structure of EuCd_(2)As_(2). | Yingkai Sun Yong Li Shuaishuai Li Changjiang Yi Hanbin Deng Xin Du Limin Liu Changjiang Zhu Yuan Li Zheng Wang Hanqing Mao Youguo Shi Rui Wu | 2022 | Journal of Rare Earths2022,40,10: | 0 |
| 17 | Favorable anion adsorption/desorption of high rate NiSe_(2) nanosheets/hollow mesoporous carbon for battery-supercapacitor hybrid devices显示文摘High-rate battery-type cathode materials have attracted wide attention for advanced battery-supercapacitor hybrid(BSH)devices.Herein,a core-shell structure of the hollow mesoporous carbon spheres(HMCS)supported NiSe2 nanosheets(HMCS/NiSe2)is constructed through two-step reactions.The HMCS/NiSe_(2)shows a max specific capacity of 1,153.5 C·g^(-1) at the current density of 1 A·g^(-1),and can remain at 774.5 C·g^(-1) even at 40 A·g^(-1)(the retention rate as high as 67.1%)and then the HMCS/NiSe_(2) electrode can keep 80.5%specific capacity after 5,000 cycles at a current density of 10 A·g^(-1).Moreover,the density functional theory(DFT)calculation confirmed that the introduction HMCS into NiSe_(2) made adsorption/desorption of OH-easier,which can achieve higher rate capability.The HMCS/NiSe_(2)//6 M KOH//HMCS hybrid device has energy density of 47.15 Wh·kg^(-1) and power density of 801.8 W·kg^(-1).This work provides a feasible electrode material with a high rate and its preparation method for high energy density and power density energy storage devices. | Xiaojuan Zhao Houzhao Wan Pei Liang Nengze Wang Cong Wang Yi Gan Xu Chen Qiuyang Tan Xiang Liu Jun Zhang Yi Wang Hanbin Wang Hao Wang | 2021 | Nano Research2021,14,8: | 0 |
