1SHRIMP zircon U-Pb dating for volcanic rocks of the Dasi Formation in southeast Hubei Province,middle-lower reaches of the Yangtze River and its implications显示文摘The Jinniu Basin in southeast Hubei,located at the westernmost part of middle-lower val-ley of the Yangtze River,is one of the important vol-canic basins in East China. Volcanic rocks in the Jin-niu Basin are distributed mainly in the Majiashan Formation,the Lingxiang Formation and the Dasi Formation,consisting of rhyolite,basalt and basaltic andesite,(trachy)-basalt and basaltic trachy-andesite and (trachy)-andesite and (trachy)-dacite and rhyolite respectively,in which the Dasi volcanism is volumet-rically dominant and widespread. The Dasi volcanic rocks were selected for SHRIMP zircon U-Pb dating to confirm the timing of volcanism. The results indi-cate that there exist a large amount of magmatic zir-cons characterized by high U and Th contents in the volcanic rocks. The concordia ages for 13 points are 128 ± 1Ma (MSWD = 3.0). On account of the shape of zircons and Th/U ratios,this age is considered to represent the crystallization time of the Dasi volcan-ism. The volcanic rocks in the Dasi,Majiashan and Lingxiang Formations share similar trace elementand REE partition patterns as well as Sr-Nd isotopic compositions. In combination with the regional geol-ogy,it is proposed that the southeast Hubei volcanic rocks were formed mainly during the Early Creta-ceous,just like other volcanic basins in middle-lower Yangtze valley. A lithospheric extension is also sug-gested for tectonic regime in this region in the Cre-taceous Period.XIE Guiqing MAO Jingwen LI Ruiling ZHOU Shaodong YE Huishou YAN Quanren ZHANG Zusong 2006Chinese Science Bulletin2006,51,24:38
2Plantlet regeneration of adult Pinus massoniana Lamb. trees using explants collected in March and thidiazuron in culture medium显示文摘A protocol for micropropagation using nodal explants from mature Pinus massoniana trees has been developed. Time of explant collection is crucial for the initial success of aseptic culture. Explants collected in early March gave the highest percentage of explant survival(64.5%) and shoot-forming percentage(52.3%). Thidiazuron(TDZ) concentration significantly influenced shoot formation; 4 μM TDZ was optimum, with 4.8 shoots produced per explant with a mean length of 7.1 cm after 120 days of culture. Regenerated shoots rooted for 60 days in basic medium with 1μM NAA were ready for growth in pots. This is the first report on plantlet regeneration in vitro from mature trees of P. massoniana that provides a reliable method for propagating selected elites.Yin Wang Ruiling Yao 2017Journal of Forestry Research2017,28,6:12
3Jurassic Intra-plate Basaltic Magmatism in Southeast China:Evidence from Geological and Geochemical Characteristics of the Chebu Gabbroite in Southern Jiangxi Province显示文摘Geochemical and isotopic investigations have been carried out on the Chebu gabbroite in southern Jiangxi Province, southeast China and these results are compared with gabbro bodies along the coast of Fujian Province in order to understand their magma sources and tectonic implications. The Chebu intrusion formed at the beginning of the Middle Jurassic (172±4.3 Ma). These rocks are Ti-rich and Al-poor in major elements, characterized by strong enrichment in large-ion lithophile elements (LILE) and moderate enrichment in high field strength elements (HFSE) and light rare-earth elements (LREE), without pronounced Nb or Ta anomalies. Age-correlated Sr-Nd isotope ratios show moderately high ranges of (87Sr/86Sr)i from 0.7065 to 0.7086 and 0.5124 to 0.5125 of (143Nd/144Nd)i. The geochemical characteristics of the Chebu gabbroite suggest that it is notably different from island-arc basalt and similar to intra-plate basaltic rocks. By combining interpretations of its geological and geochemical characteristics and the regional geological development history, the Chebu gabbroitic intrusion is thought to be the product of asthenosphere upwelling and rapid lithosphere extension during a transition of tectonic systems in southeast China. The tectonic environment and source characteristics of the intrusion are different from Cretaceous gabbro bodies along the coast of Fujian Province, The former formed in a tectonic environment of rapid intra-plate lithospheric extension and the source characteristics were of a weakly enriched primitive mantle, whereas the latter originated mainly in a volcanic-magmatic arc extensional tectonic environment and the nature of the source was an enriched mantle with more subduct subducted components.XIE Guiqing MAO Jingwen HU Ruizhong LI Ruiling JIANG Guohao CAO Jinjian ZHAO Junhong 2005Acta Geologica Sinica(English Edition)2005,79,5:10
4Effect of Intermetallic Phases on Corrosion Initiation of AZ91 Alloy With Rare Earth Y Addition显示文摘The effect of the rare earth(RE) element Y on the microstructure of AZ91 Mg alloy is investigated.A detailed description of the procedure of identifying the intermetallic phases containing Y in the AZ91 Mg alloy with 0.9 wt%Y addition is presented.The results shows that there are two different kinds of RE phases in scanning electron microscopy(SEM) images.Energy dispersive spectrum(EDS) analysis shows that one is rich in Y element and the other is rich in Mn element.According to the element mapping of electron probe microanalysis(EPMA).the element Al can be found not only in the β-Mg_(17)Al_(12) phase but also in these two RE phases.X-ray diffraction(XRD) and transmission electron microscopy(TEM) results further confirm one of the two RE phases is AI2Y;the phase of Al_(10)Mn_2Y has just been determined by transmission electron microscopy(TEM) instead of XRD probably because it is scarce.The shapes of these two RE intermetallic phases are pretty similar.The 3D digital microscopy is employed to observe in-situ the effect of the(5 phase and the above two RE intermetallic phases on the corrosion initiation of the alloys.The results show that the corrosion attack of AZ91 Mg alloy without Y addition starts around the eutectic phase β-Mg_(17)Al_(12).With the addition of 0.9 wt%Y,the two kinds of Y-rich intermetallic phases act as cathodic effect and a phase in the adjacent of them was activated and cathodic effect of the β-Mg_(17)Al_(12)phase was inhibited.Li-na Zhang Ruiling Jia Dan Li Wei Zhang Feng Guo 2015Journal of Materials Science & Technology2015,31,5:8
5Enhanced antitumor efficacy on hepatoma-bearing rats with adriamycin-loaded nanoparticles administered into hepatic artery显示文摘AIM: To investigate the antitumor activity of adriamycin (ADR) encapsulated in nanoparticles (NADR) and injected into the hepatic artery of hepatoma-bearing rats.METHODS: NADR was prepared by the interfacial polymerization method. Walker-256 carcinosarcomas were surgically implanted into the left liver lobes of 60 male Wistar rats, which were divided into 4 groups at random (15 rats per group). On the 7th day after implantation, normal saline (NS), free ADR (FADR), NADR, or ADR mixed with unloaded nanoparticles (ADR+NP) was respectively injected via the hepatic artery (i.a.) of rats in different groups. The dose of ADR in each formulation was 2.0 mg/kg body weight and the concentration was 1.0 mg/mL. Survival time, tumor enlargement ratio, and tumor necrosis degree were compared between each group.RESULTS: Compared with the rats that received NS i.a.,the rats that received FADR or ADR+NP acquired apparent inhibition on tumor growth, as well as prolonged their life span. Further significant anticancer efficacy was observed in rats that received i.a. administration of NADR. Statistics indicated that NADR brought on a more significant tumor inhibition and more extensive tumor necrosis, as compared to FADR or ADR+NP. The mean tumor enlargement ratio on the 7th day after NADR i.a. was 1.106. The mean tumorbearing survival time was 39.50 days. Prolonged life span ratio was 109.22% as compared with rats that accepted NS.CONCLUSION: Therapeutic effect of ADR on liver malignancy can be significantly enhanced by its nanopaticle formulation and administration via hepatic artery.Jiang-HaoChen RuiLing QingYao LingWang ZhongMa YuLi ZheWang HuXu 2004World Journal of Gastroenterology2004,10,13:8
6Zacopride selectively activates the Kir2.1 channel via a PKA signaling pathway in rat cardiomyocytes显示文摘We recently reported that zacopride is a selective inward rectifier potassium current (IK1 ) channel agonist, suppressing ventricular arrhythmias without affecting atrial arrhythmias. The present study aimed to investigate the unique pharmacological properties of zacopride. The whole-cell patch-clamp technique was used to study IK1 currents in rat atrial myocytes and Kir2.x currents in human embryonic kidney (HEK)-293 cells transfected with inward rectifier potassium channel (Kir)2.1, Kir2.2, Kir2.3, or mutated Kir2.1 (at phosphorylation site S425L). Western immunoblots were performed to estimate the relative protein expression levels of Kir2.x in rat atria and ventricles. Results showed that zacopride did not affect the IK1 and transmembrane potential of atrial myocytes. In HEK293 cells, zacopride increased Kir2.1 homomeric channels by 40.7%±9.7% at 50 mV, but did not affect Kir2.2 and Kir2.3 homomeric channels, and Kir2.1-Kir2.2, Kir2.1-Kir2.3 and Kir2.2-Kir2.3 heteromeric channels. Western immunoblots showed that similar levels of Kir2.3 protein were expressed in rat atria and ventricles, but atrial Kir2.1 protein level was only 25% of that measured in the ventricle. In addition, 5-hydroxytryptamine (5-HT) 3 receptor was undetectable, whereas 5-HT 4 receptor was weakly expressed in HEK293 cells. The Kir2.1-activating effect of zacopride in these cells was abolished by inhibition of protein kinase A (PKA), but not PKC or PKG. Furthermore, zacopride did not activate the mutant Kir2.1 channel in HEK293 cells but selectively activated the Kir2.1 homomeric channel via a PKA-dependent pathway, independent to that of the 5-HT receptor.ZHANG Li LIU QingHua LIU ChengFang ZHAI XuWen FENG QiLong XU RuiLing CUI XiangLi ZHAO ZhiQing CAO JiMin WU BoWei 2013Science China(Life Sciences)2013,56,9:7
7Alginate oligosaccharide improves resistance to postharvest decay and quality in kiwifruit(Actinidia deliciosa cv. Bruno)显示文摘Kiwifruit is an extremely perishable fruit;postharvest disease and senescence during storage can reduce the fruit quality,resulting in economic loss.Considerable research effort has focused on identifying safe and cost-effective ways to preserve fresh kiwifruit.To this end,the present study investigated the effects of alginate oligosaccharide(AOS)soaking treatment on postharvest quality and disease in the‘Bruno’variety of kiwifruit.The involved physiological mechanisms were further explored.The results showed that AOS did not inhibit the growth of Botrytis cinerea in vitro,the causal agent of gray mold in kiwifruit,but reduced the incidence of gray mold and diameter of lesions of kiwifruit during storage.Kiwifruit treated with 50 mg·L-1 AOS showed a higher degree of firmness and lower soluble solid content than control fruit treated with distilled water.Moreover,AOS treatment inhibited the activity of polygalacturonase and pectinesterase,while enhancing the activity of polyphenoloxidase,l-phenylalanine ammonia lyase andβ-1,3-glucanase related to pathogen defense,and also improved total antioxidant capacity determined by the DPPH,FRAP,and ABTS methods in kiwifruit.These results indicate that 50 mg·L-1 AOS can confer disease resistance in kiwifruit during storage.Ruiling Zhuo Boqiang Li Shiping Tian 2022Horticultural Plant Journal2022,8,1:6
8Arabidopsis ANAC092 regulates auxin-mediated root development by binding to the ARF8 and PIN4 promoters显示文摘Auxin is an important plant hormone that is essential for growth and development due to its effects on organogenesis, morphogenesis, tropisms, and apical dominance. The functional diversity of auxin highlights the importance of its biosynthesis, transport, and associated responses. In this study, we show that a NAC transcription factor, ANAC092(also named At NAC2 and ORESARA1),known to positively regulate leaf senescence and contribute to abiotic stress responses, also affects primary root development. Plants overexpressing ANAC092 had altered root meristem lengths and shorter primary roots compared with the wild-type control. Additionally, expression of the pro ANAC092::GUS was strongly induced by indole-3-acetic acid. Quantitative real-time RT-PCR(q RT-PCR) analysis revealed that the YUCCA2, PIN, and ARF expression levels were downregulated in ANAC092-overexpressing plants. Moreover, yeast one-hybrid and chromatin immunoprecipitation assays confirmed that ANAC092 binds to the promoters of AUXIN RESPONSE FACTOR 8(ARF8) and PIN-FORMED 4(PIN4). Furthermore, a dual-luciferase assay indicated that ANAC092 decreases ARF8 and PIN4 promoter activities. We also applied a CRISPR/Cas9 system to mutate ANAC092. The roots of three of the analyzed mutants were longer than normal. Collectively, our findings indicate that ANAC092 negatively affects root development by controlling the auxin pathway.Dandan Xi Xu Chen Yuxia Wang Ruiling Zhong Jianmei He Jiabin Shen Feng Ming 2019Journal of Integrative Plant Biology2019,61,9:6
9Tectonic and Environmental Evolutions of the Northern Tibetan Plateau Prior to the Collision of India with Asia显示文摘Tectonic and environmental patterns and evolution of the present North Tibetan Plateau(NTP) prior to the India collision with Asia is significant to understand the formation of the Tibetan Plateau and its influence on the environment. In this study, we integrated and analyzed the tectonostratigraphy and the special sedimentary layers whose climatic implications are clear in the NTP. Additionally, we stressed the tectonic and environmental events and their evolutions from the Mesozoic to the Early Cenozoic. Our results show that four tectonic phases, which sequentially took place during the Triassic, Jurassic, Cretaceous and Paleogene, played an important role on the formation of the North Tibet. The climate was basically dry and hot from the Triassic to the Eocene and became dry and cool since the Oligocene in this region. The climatic evolution was characterized by a transition from a wet and hot phase during the Triassic- Middle Jurassic, to a dry and hot phase during the Late Jurassic- Eocene. Both phases encompassed 5 wet and hot periods followed by 5 dry and hot climate events, respectively. In addition, we found that the tectonic deformation and the climatic conditions were spatially and temporally different. In detail, in the regions north of the PaleoTian Shan and Paleo-Qilian Mts. the tectonic deformation and climatic condition were stronger and wetter than in regions south of the Paleo-Tian Shan and Paleo-Qilian Mts. during the Late Triassic – Jurassic. Whereas in the Cretaceous, the tectonic movement was intensive in the west but steady in the east, and climate was dry in the south but wet in the north of NTP. The formation of the tectonic and climatic patterns in NTP were the consequence of either global climate change or regional tectonics, including the Paleo-Asian Ocean closure and the Qiangtang block, Lhasa block and India plate collision subsequently to Asia. Furthermore, the regional tectonic events occurred before any global climate change and drove the climatic change in the NTP.DAI Shuang ZHANG Mingzhen PENG Dongxiang WANG Huawei WU Maoxian CHEN Ruiling ZHANG Xiang 2014Acta Geologica Sinica(English Edition)2014,88,2:6
10Regulation of phenylpropanoid biosynthesis by MdMYB88 and MdMYB124 contributes to pathogen and drought resistance in apple显示文摘MdMYB88 and MdMYB124 have been demonstrated to be responsible for lignin accumulation in apple under drought stress.In this study,using a metabolomic approach,we identified differentially accumulated phenylpropanoid and flavonoid metabolites in MdMYB88/124 transgenic RNAi plants under control and long-term drought stress conditions in apple roots.We confirmed the regulation of phenylalanine by MdMYB88 and MdMYB124 via UPLC-MS in apple roots under both control and drought conditions.Using Electrophoretic Mobility Shift Assay(EMSA)and ChIPquantitative PCR(qPCR)analyses,we found that MdMYB88 positively regulates the MdCM2 gene,which is responsible for phenylalanine biosynthesis,through binding to its promoter region.Under long-term drought conditions,MdMYB88/124 RNAi plants consistently accumulated increased amounts of H2O2 and MDA,while MdMYB88 and MdMYB124 overexpression plants accumulated decreased amounts of H2O2 and MDA.We also examined the accumulation of metabolites in the phenylpropanoid biosynthesis pathway in the leaves of MdMYB88 and MdMYB124 transgenic apple plants after long-term drought stress.We found that metabolites responsible for plant defense,including phenylpropanoids and flavonoids,accumulated less in the RNAi plants but more in the overexpression plants under both control and drought conditions.We further demonstrated that MdMYB88/124 RNAi plants were more sensitive to Alternaria alternata f.sp.mali and Valsa mali,two pathogens that currently severely threaten apple production.In contrast,MdMYB88 and MdMYB124 overexpression plants were more tolerant to these pathogens.The cumulative results of this study provided evidence for secondary metabolite regulation by MdMYB88 and MdMYB124,further explained the molecular roles of MdMYB88 and MdMYB124 in drought resistance,and provided information concerning molecular aspects of their roles in disease resistance.Dali Geng Xiaoxia Shen Yinpeng Xie Yusen Yang Ruiling Bian Yuqi Gao Pengmin Li Liying Sun Hao Feng Fengwang Ma Qingmei Guan 2020Horticulture Research2020,7,1:5
11Spatial-temporal Evolution Characteristics and Decoupling Analysis of Influencing Factors of China’s Aviation Carbon Emissions显示文摘The aviation industry has become one of the top ten greenhouse gas emission industries in the world. China’s aviation carbon emissions continue to increase, but the analysis of its influencing factors at the provincial level is still incomplete. This paper firstly uses Stochastic Impacts by Regression on Population, Affluence and Technology model(STIRPAT) model to analyze the time series evolution of China’s aviation carbon emissions from 2000 to 2019. Secondly, it uses the Logarithmic Mean Divisia Index(LDMI) model to analyze the influencing characteristics and degree of four factors on China’s aviation carbon emissions, which are air transportation revenue, aviation route structure, air transportation intensity and aviation energy intensity. Thirdly, it determines the various factors’ influencing direction and evolution trend of 31 provinces’ aviation carbon emissions in China(not including Hong Kong, Macao, Taiwan of China due to incomplete data). Finally, it derives the decoupling effort model and analyzes the decoupling relationship and decoupling effort degree between air carbon emissions and air transportation revenue in different provinces. The study found that from 2000 to2019, China’s total aviation carbon emissions continued to grow, while the growth rate of aviation carbon emissions showed a fluctuating downward trend. Air transportation revenue and aviation route structure promote the growth of total aviation carbon emissions, and air transportation intensity and aviation energy intensity have a restraining effect on the growth of total aviation carbon emissions. The scope of negative driving effect of air transportation revenue and air transportation intensity on total aviation carbon emissions in various provinces has increased. While the scope of positive driving influence of aviation route structure on total aviation carbon emissions of various provinces has increased, aviation energy intensity mainly has negative driving influence on total aviation carbon emissions of each province. Overall, the emission reduction trend in the areas to the west and north of the Qinling-Huaihe River Line is obvious. The decoupling mode between air carbon emissions and air transportation revenue in 31 provinces is mainly expansion negative decoupling.The air transportation intensity effect shows strong decoupling efforts in most provinces, the decoupling effort of aviation route structure effect and aviation energy intensity effect is not prominent.HAN Ruiling LI Lingling ZHANG Xiaoyan LU Zi ZHU Shaohua 2022Chinese Geographical Science2022,32,2:5
12Research progress in electrospinning engineering for all-solid-state electrolytes of lithium metal batteries显示文摘Owing to safety issue and low energy density of liquid lithium-ion batteries(LIBs),all-solid-state lithium metal batteries(ASLMBs)with unique all-solid-state electrolytes(SEs)have attracted wide attentions.This arises mainly from the advantages of the SEs in the suppression of lithium dendrite growth,long cycle life,and broad working temperature range,showing huge potential applications in electronic devices,electric vehicles,smart grids,and biomedical devices.However,SEs suffer from low lithiumion conductivity and low mechanical integrity,slowing down the development of practical ASLMBs.Nanostructure engineering is of great efficiency in tuning the structure and composition of the SEs with improved lithium-ion conductivity and mechanical integrity.Among various available technologies for nanostructure engineering,electrospinning is a promising technique because of its simple operation,cost-effectiveness,and efficient integration with different components.In this review,we will first give a simple description of the electrospinning process.Then,the use of electrospinning technique in the synthesis of various SEs is summarized,for example,organic nanofibrous matrix,organic/inorganic nanofibrous matrix,and inorganic nanofibrous matrix combined with other components.The current development of the advanced architectures of SEs through electrospinning technology is also presented to provide references and ideas for designing high-performance ASLMBs.Finally,an outlook and further challenges in the preparation of advanced SEs for ASLMBs through electrospinning engineering are given.Manxi Wang Yaling Wu Min Qiu Xuan Li Chuanping Li Ruiling Li Jiabo He Ganggang Lin Qingrong Qian Zhenhai Wen Xiaoyan Li Ziqiang Wang Qi Chen Qinghua Chen Jinhyuk Lee Yiu-Wing Mai Yuming Chen 2021Journal of Energy Chemistry2021,30,10:4
13Damage of hippocampal neurons in rats with chronic alcoholism显示文摘Chronic alcoholism can damage the cytoskeleton and aggravate neurological deficits. However, the effect of chronic alcoholism on hippocampal neurons remains unclear. In this study, a model of chronic alcoholism was established in rats that were fed with 6% alcohol for 42 days. Endogenous hydrogen sulfide content and cystathionine-beta-synthase activity in the hippocampus of rats with chronic alcoholism were significantly increased, while F-actin expression was decreased. Hippocampal neurons in rats with chronic alcoholism appeared to have a fuzzy nuclear membrane, mitochondrial edema, and ruptured mitochondrial crista. These findings suggest that chronic alcoholism can cause learning and memory decline in rats, which may be associated with the hydrogen sulfide/cystathionine-beta-synthase system, mitochondrial damage and reduced expression of F-actin.Ailin Du Hongbo Jiang Lei Xu Na An Hui Liu Yinsheng Li Ruiling Zhang 2014Neural Regeneration Research2014,9,17:3
14Histone acetylation of the htr3a gene in the prefrontal cortex of Wistar rats regulates ethanol-seeking behavior显示文摘Previous reports showed that decreased histone deacetylase activity significantly potentiated the rewarding effects of psychostimulants,and that encoding of the 5-HT3 receptor by the htr3a gene was related to ethanol-seeking behavior.However,the effects of a histone deacetylase inhibitor on ethanol-seeking behavior and epigenetic regulation of htr3a mRNA expression after chronic ethanol exposure are not fully understood.Using quantitative reverse transcription-polymerase chain reaction and chromatin immunoprecipitation analysis,we investigated the effects of chronic ethanol exposure and its interaction with a histone deacetylase inhibitor on histone-acetylation-mediated changes in htr3a mRNA expression in the htr3a promoter region.The conditioned place preference procedure was used to evaluate ethanol-seeking behavior.Chronic exposure to ethanol effectively elicited place conditioning.In the prefrontal cortex,the acetylation of H3K9 and htr3a mRNA expression in the htr3a promoter region were significantly higher in the ethanol group than in the saline group.The histone deacetylase inhibitor sodium butyrate potentiated the effects of ethanol on htr3a mRNA expression and enhanced ethanol-induced conditioned place preferences.These results suggest that ethanol upregulates htr3a levels through mechanisms involving H3K9 acetylation,and that histone acetylation may be a therapeutic target for treating ethanol abuse.Yahui Xu Xuebing Liu Xiaojie Zhang Guanbai Zhang Ruiling Zhang Tieqiao Liu Wei Hao 2012Neural Regeneration Research2012,7,13:3
15Noncontrast-enhanced MRI-based Noninvasive Score for Portal Hypertension(CHESS1802):An International Multicenter Study显示文摘Background and Aims:This study aimed to determine the performance of the non-invasive score using noncontrastenhanced MRI(CHESS-DIS score)for detecting portal hy-pertension in cirrhosis.Methods:In this international multicenter,diagnostic study(ClinicalTrials.gov,NCT03766880),patients with cirrhosis who had hepatic venous pressure gradient(HVPG)measurement and noncontrast-enhanced MRI were prospectively recruited from four university hospitals in China(n=4)and Turkey(n=1)between December 2018 and April 2019.A cohort of patients was retrospectively recruited from a university hospital in Italy between March 2015 and November 2017.After segmentation of the liver on fat-suppressed T1-weighted MRI maps,CHESS-DIS score was calculated automatically by an in-house developed code based on the quantification of liver surface nodularity.Results:A total of 149 patients were included,of which 124 were from four Chinese hospitals(training cohort)and 25 were from two international hospitals(validation cohort).A positive correlation between CHESS-DIS score and HVPG was found with the correlation coefficients of 0.36(p<0.0001)and 0.55(p<0.01)for the training and validation cohorts,respectively.The area under the receiver operating characteristic curve of CHESS-DIS score in detection of clinically significant portal hypertension(CSPH)was 0.81 and 0.9 in the training and validation cohorts,respectively.The intra-class correlation coefficients for assessing the inter-and intra-observer agreement were 0.846 and 0.841,respectively.Conclusions:A non-invasive score using noncontrast-enhanced MRI was developed and proved to be significantly correlated with invasive HVPG.Besides,this score could be used to detect CSPH in patients with cirrhosis.Yanna Liu Tianyu Tang NecatiÖrmeci Yifei Huang Jitao Wang Xiaoguo Li Zhiwei Li Weimin An Dengxiang Liu Chunqing Zhang Changchun Liu Jinqiang Liu Chuan Liu Guangchuan Wang Cristina Mosconi Alberta Cappelli Antonio Bruno Seray Akçalar EmrecanÇelebioğlu EvrenÜstüner Sadık Bilgiç Zeynep Ellik ÖzgünÖmer Asiller Lei Li Haijun Zhang Ning Kang Dan Xu Ruiling He Yan Wang Yang Bu Ye Gu Shenghong Ju Rita Golfieri Xiaolong Qi 2021Journal of Clinical and Translational Hepatology2021,9,6:3

17Bismuth doped lead-free two-dimensional tin based halide perovskite single crystals显示文摘Heterovalent-metal doping is an efficient tool to tune the optoelectronic properties of the famous halide perovskites.Previous studies have focused on the heterovalent-doping in three-dimensional(3D) halide perovskites.However, there is a lack of such doping in two-dimensional perovskites which possess unique optoelectronic properties and improved chemical stability as compared to 3D analogues.Here, we present successful doping of Bismuth into the lattice of lead-free, two-dimensional perovskite PEA2SnBr4 single crystals.Structural characterizations demonstrate that the doped crystals possess identical crystal structure and layered morphology with the pristine one.Intriguingly, we find the PL peak and spectral shape can be tailored by tuning the concentration of Bi dopants.Femtosecond transient absorption spectroscopy is performed to understand the underlying mechanism related to tunable PL behaviors, and a clear picture of the Bismuth-doping impact is provided.Ruiling Zhang Xin Mao Pengfei Cheng Yang Yang Songqiu Yang Tuerdi Wumaier Weiqiao Deng Keli Han 2019Journal of Energy Chemistry2019,28,9:2
