| 1 | In situ SIMS oxygen isotope analyses: Evidence for the formation of aluminum-rich chondrules from ordinary chondrites显示文摘Aluminum-rich chondrules(ARCs),which share mineralogic and chemical properties with both Ca,Al-rich inclusions(CAIs)and ferromagnesian chondrules,play an important role in revealing their temporal and petrogenetic relationships.In this work,seven ARCs were found in three ordinary chondrites GRV 022410(H4),GRV 052722(H3.7)and Julesburg(L3.6).They contain bulk Al2O3~17%-33%and exhibit igneous textures composed of olivine,high-and low-Ca pyroxene,plagioclase,spinel and glass.In situ SIMS analyses show that ARCs have oxygen isotopic compositions(δ18O=–6.1‰–7.1‰;δ17O=–4.5‰–5.1‰)close to ferromagnesian chondrules but far more depleted in 16O than CAIs(δ18O=-40‰;δ17O=-40‰).Most ARCs plot close to the terrestrial mass fractionation(TF)line,and a few between the TF and carbonaceous chondrite anhydrous mixing(CCAM)lines.Plagioclase,nepheline and glass suffered O-isotopic exchanges during the metamorphism processes in the parent body.Spinel,olivine and pyroxene represent the primary O-isotopic compositions of ARCs,and define a fitted line with a slope of^0.7±0.1.Compared with the results of previous studies,shallower slope as well as more depleted16O compositions further demonstrates that ARCs in ordinary chondrites are not a simple mixing product of ferromagnesian chondrules and CAIs.Instead,they probably experienced higher-degree oxygen isotope exchange with a 16O-poor nebular gas reservoir during multiple melting episodes. | JIANG Yun HSU WeiBiao GUAN YunBin WANG Ying | 2015 | Science China Earth Sciences2015，58，10： | 4 |
| 2 | Randomized,multicenter,open-label trial of autologous cytokine-induced killer cell immunotherapy plus chemotherapy for squamous non-small-cell lung cancer:NCT01631357显示文摘Dear Editor,Cytokine-induced killer(CIK)cells have been recognized as a new type of anti-tumor effector cells.CIK cells are a mixture of T lymphocytes.Among them,CD3+/CD56+T cells,which are rare in uncultured peripheral blood,are the main effector cells.CIK cells can proliferate rapidly in vitro,with stronger antitumor activity,broader target tumor spectrum,and lower adverse effect than other reported antitumor effector cells.1 Their ease of production in vitro and antitumor potential have made them suitable candidates for cell therapy regimens in solid and hematopoietic tumor treatments.1,2 Our previous retrospective study showed that the median progression-free survival(PFS)and overall survival(OS)in untreated,advanced non-small-cell lung cancer(NSCLC)patients who received CIK cell immunotherapy plus chemotherapy(13 and 24 months,respectively)were significantly longer than in those who received chemotherapy alone(6 and 10 months,respectively).2 But so far,there is no prospective,multicenter clinical study in lung cancer.Based on our previous study,we designed this randomized,multicenter,open-label trial to further evaluate the clinical efficacy of CIK cell immunotherapy plus chemotherapy in patients with advanced squamous NSCLC(ClinicalTrials.gov number,NCT01631357). | Liang Liu Quanli Gao Jingting Jiang Junping Zhang Xin Song Jiuwei Cui Yunbin Ye Zhiyu Wang Xinwei Zhang Xiubao Ren | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 2 |
| 3 | Realizing simultaneously excellent energy storage and discharge properties in AgNbO_(3)based antiferroelectric ceramics via La^(3t)and Ta^(5+)co-substitution strategy显示文摘AgNbO_(3)based antiferroelectric(AFE)ceramics have large maximum polarization and low remanent polarization,and thus are important candidates for fabricating dielectric capacitors.However,their energy storage performances have been still large difference with those of lead-based AFEs because of their room-temperature ferrielectric(FIE)behavior.In this study,novel La^(3+)and Ta^(5+)co-substituted AgNbO_(3)ceramics are designed and developed.The introduction of La^(3+)and Ta^(5+)decreases the tolerance factor,reduces the polarizability of B-site cations and increases local structure heterogeneity of AgNbO_(3),which enhance AFE phase stability and refine polarization-electric field(PeE)loops.Besides,adding La^(3+)and Ta^(5+)into AgNbO_(3)ceramics causes the decrease of the grain sizes and the increase of the band gap,which contribute to increased Eb.As a consequence,a high recoverable energy density of 6.79 J/cm3 and large efficiency of 82.1%,which exceed those of many recently reported AgNbO_(3)based ceramics in terms of overall energy storage properties,are obtained in(Ag0.88La0.04)(Nb0.96Ta0.04)O_(3)ceramics.Furthermore,the discharge properties of the ceramic with discharge time of 16 ns and power density of 145.03 MW/cm3 outperform those of many lead-free dielectric ceramics. | Yuqi Zhou Shuaibing Gao Jie Huang Meng Shen Shenglin Jiang Yunbin He Qingfeng Zhang | 2023 | Journal of Materiomics2023，9，2： | 0 |
| 4 | Lignocellulosic fraction-induced niche differentiation within dissimilatory iron reducing bacterial groups in a paddy soil显示文摘Responses of soil DIRB to lignocellulosic fractions during a 6-week microcosm incubation were investigated.Anaeromyxobacter,Bacillus,and Clostridium maintained their domi-nance throughout the incubation.Distinct DIRB groups proliferated under specific lignocellulosic fraction amendments.Limits of insufficient ferric iron on the proliferation varied by DIRB group.Dissimilatory iron reducing bacteria(DIRB)are phylogenetically and physi-ologically diverse in paddy soils,where iron reduction closely couples with the oxidation of rice straw-derived carbon in the straw returning scenarios.However,few studies have addressed the niche differentiation within DIRB groups during the degradation of lignocellulosic fractions of rice straw.This study conducted a 6-week microcosm incubation experiment to reveal the distinct responses of DIRB groups under specific lignocellulosic fraction amendments with and without ferrihydrite(Fh)addition in a flooded paddy Ultisol.Results showed that the total absolute abundance of the 19 detected DIRB groups did not vary significantly during the incubation.Anaeromyxobacter,Bacillus,and Clostridium were the dominant DIRB groups for all lignocellulosic treatments whereas Thermincola was dominant but only under xylan amendment with Fh addition.DIRB-nodes in the co-occurrence networks of bacterial community mainly belonged to Anaeromyxobacter and Bacillus.Clostridium and Thermincola,Alkaliphilus and Anaeromyxobacter,and Alicyclobacillus,Desulfobulbus,and Desulfosporosinus were specifically proliferated under xylan,cellulose,and lignin amendments,respectively.Whether the proliferation was limited by insufficient ferric iron varied by bacterial group.These findings suggested the lignocellulosic fraction-induced niche differentiation within DIRB groups,which advanced our understanding of the ecology of DIRB in paddy soils under straw returning. | Yunbin Jiang Wenting Hu Kailou Liu Shangshu Huang Fengwu Zhou Cheng Han Huan Deng Wenhui Zhong | 2024 | Soil Ecology Letters2024，6，1： | 0 |
| 5 | Indication of Soil Microbial Activity by Electrical Signals of Microbial Fuel Cells with Re-Vegetated Red Soils显示文摘Electrical signals generated by microbial fuel cells(MFCs)may potentially indicate overall soil microbial activity.This study aimed to validate whether a significant correlation existed between soil microbial activity and electrical signals in different soils.Re-vegetated red soils with four vegetation types and unplanted eroded red soil were collected and packed into MFCs.The voltage of the MFCs was recorded during operation.Electrical signals including start-up time(ST),peak voltage,and coulomb quantity were extracted from the voltage curves.Soil dehydrogenase activity(DHA) was determined as a reference method to verify the reliability of the electrical signals.After MFC operation,the anodic bacterial community was analyzed by Illumina sequencing based on the 16S rRNA gene.The results indicated that ST was significantly correlated with DHA,along with soil organic carbon content.The linear regression model described the optimal relationships for ST and DHA.Clostridium and Acinetobacter constituted the dominant genera on the anode of the MFCs.The results demonstrated that ST may indicate soil microbial activity in re-vegetated red soils. | JIANG Yunbin DENG Huan QIN Hongyi HAN Cheng ZHONG Wenhui | 2018 | Pedosphere2018，28，2： | 0 |
