| 1 | Sulfur speciation and bioaccumulation in camphor tree leaves as atmospheric sulfur indicator analyzed by synchrotron radiation XRF and XANES显示文摘Analyzing and understanding the effects of ambient pollution on plants is getting more and more attention as a topic of environmental biology.A method based on synchrotron radiation X-ray fluorescence and X-ray absorption near edge structure spectroscopy was established to analyze the sulfur concentration and speciation in mature camphor tree leaves (CTLs),which were sampled from 5 local fields in Shanghai,China.Annual SO2 concentration,SO42-concentration in atmospheric particulate,SO42-and sulfur concentration in soil were also analyzed to explore the relationship between ambient sulfur sources and the sulfur nutrient cycling in CTLs.Total sulfur concentration in mature camphor tree leaves was 766-1704 mg/kg.The mainly detected sulfur states and their corresponding compounds were +6 (sulfate,include inorganic sulfate and organic sulfate),+5.2 (sulfonate),+2.2 (suloxides),+0.6 (thiols and thiothers),+0.2 (organic sulfides).Total sulfur concentration was strongly correlated with sulfate proportion with a linear correlation coefficient up to 0.977,which suggested that sulfur accumulated in CTLs as sulfate form.Reduced sulfur compounds (organic sulfides,thiols,thioethers,sulfoxide and sulfonate) assimilation was sufficed to meet the nutrient requirement for growth at a balanced level around 526 mg/kg.The sulfate accumulation mainly caused by atmospheric sulfur pollution such as SO2 and airborne sulfate particulate instead of soil contamination.From urban to suburb place,sulfate in mature CTLs decreased as the atmospheric sulfur pollution reduced,but a dramatic increase presented near the seashore,where the marine sulfate emission and maritime activity pollution were significant.The sulfur concentration and speciation in mature CTLs effectively represented the long-term biological accumulation of atmospheric sulfur pollution in local environment. | Jianrong Zeng Guilin Zhang Liangman Bao Shilei Long Mingguang Tan Yan Li Chenyan Ma Yidong Zhao | 2013 | Journal of Environmental Sciences2013，25，3： | 9 |
| 2 | Folate receptor-mediated boron-10 containing carbon nanoparticles as potential delivery vehicles for boron neutron capture therapy of nonfunctional pituitary adenomas显示文摘Invasive nonfunctional pituitary adenomas(NFPAs) are difficult to completely resect and often develop tumor recurrence after initial surgery.Currently,no medications are clinically effective in the control of NFPA.Although radiation therapy and radiosurgery are useful to prevent tumor regrowth,they are frequently withheld because of severe complications.Boron neutron capture therapy(BNCT) is a binary radiotherapy that selectively and maximally damages tumor cells without harming the surrounding normal tissue.Folate receptor(FR)-targeted boron-10 containing carbon nanoparticles is a novel boron delivery agent that can be selectively taken up by FR-expressing cells via FR-mediated endocytosis.In this study,FR-targeted boron-10 containing carbon nanoparticles were selectively taken up by NFPAs cells expressing FR but not other types of non-FR expressing pituitary adenomas.After incubation with boron-10 containing carbon nanoparticles and following irradiation with thermal neutrons,the cell viability of NFPAs was significantly decreased,while apoptotic cells were simultaneously increased.However,cells administered the same dose of FR-targeted boron-10 containing carbon nanoparticles without neutron irradiation or received the same neutron irradiation alone did not show significant decrease in cell viability or increase in apoptotic cells.The expression of Bcl-2 was down-regulated and the expression of Bax was up-regulated in NFPAs after treatment with FR-mediated BNCT.In conclusion,FR-targeted boron-10 containing carbon nanoparticles may be an ideal delivery system of boron to NFPAs cells for BNCT.Furthermore,our study also provides a novel insight into therapeutic strategies for invasive NFPA refractory to conventional therapy,while exploring these new applications of BNCT for tumors,especially benign tumors. | DAI CongXin CAI Feng HWANG Kuo Chu ZHOU YongMao ZHANG ZiZhu LIU XiaoHai MA SiHai YANG YaKun YAO Yong FENG Ming BAO XinJie LI GuiLin WEI JunJi JIAO YongHui WEI ZhenQing MA WenBin WANG RenZhi | 2013 | Science China(Life Sciences)2013，56，2： | 8 |

| 4 | Microstructure and strength of a tantalum-tungsten alloy after cold rolling from small to large strains显示文摘Microstructural evolution of a refractory tantalum-tungsten alloy(Ta-4%W)after cold rolling from small to large von-Mises strains(0.12-2.7)was quantitatively studied using transmission electron microscopy.Grain subdivision was observed to take place at two levels.Geometrically necessary boundaries nearly paralleling to slip planes enclosed volumes further divided by diffuse cells and by remnants of Taylor lattices.With increasing strain,the diffuse cells evolved into clear incidental dislocation boundaries enclosing cells,while the Taylor lattices disappeared.Grain subdivision was thus intermediate between those observed in cell forming and in non-cell forming alloys.Meanwhile,the average misorientation angle across all boundaries increased while the average boundary spacing decreased.Distributions of the microstructural parameters at each strain level were found to exhibit universal scaling laws.The microstructural evolution was found closely linking to the observed high strength and strain hardening of this alloy.Based on measured microstructural parameters,the flow stress was calculated utilizing linearly addition of the strengthening by solutes,incidental dislocation boundaries(Taylor strengthening)and geometrically necessary boundaries(Hall-Petch equation).The relative contribution of each strength mechanism evolved with increasing strain and with microstructural evolution:solutes and friction stress dominated at small strains while boundaries dominated at larger strains.Calculated strengths were in close agreement with experimental tension tests and demonstrated an unexpectedly high and continuous parabolic hardening without transition across this large strain range. | Guoqiang Ma Darcy A.Hughes Andrew W.Godfrey Qiang Chen Niels Hansena Guilin Wu | 2021 | Journal of Materials Science & Technology2021，，24： | 3 |
