| 1 | Sensitive and Selective Fluorescent and Colorimetric Sensor for Ag^+ Based on the Supramolecular Self-Assembly in Semi-Water显示文摘在用超级快方法的半水的离子的 ultratrace 层次的特定的识别仍然是为环境监视的挑战。此处,我们报导一荧光灯并且 colormetric 传感器(ZH ) 基于超分子自己组装,其结构被银离子的 ultratrace 的增加破坏。这个过程支持了可见颜色改变的肉眼或与一个宽 pH 范围一起熄灭的荧光紧张。系统的研究揭示了很高的选择(0. | Taibao Wei Haili Zhang Wenting Li Wenjuan Qu Junxia Su Qi Lin Youming Zhang Hong Yao | 2017 | Chinese Journal of Chemistry2017，35，8： | 1 |
| 2 | Coking behaviors and kinetics on HZSM-5/SAPO-34 catalysts for conversion of ethanol to propylene显示文摘The coke deposition on HZSM-5/SAPO-34 composite catalysts has been studied in the conversion of ethanol to propylene. The HZSM-5/SAPO-34 composite catalysts were synthesized by hydrothermal method(ZS-HS) and fully blending(ZS-MM). The used catalysts were characterized by XRD, N_2 adsorption–desorption, TGA, TPO, elemental analysis, FTIR and XPS. The coking kinetics on both ZS-HS and ZS-MM has been investigated and their coking rate equations were obtained. The used ZS-MM catalyst had higher amount of coke and lower nC:nHthan the used ZS-HS. 90% of the coke was deposited in the micropores of ZS-HS, while almost 45% of the coke located in the micropores of ZS-MM. The coke deposited on ZS-HS catalyst was mainly graphite-like carbon species, whereas dehydrogenated coke species was the major on ZS-MM. The coking activation energy of ZS-MM was lower than that of ZS-HS, and the coking rate on ZS-MM was faster than on ZS-HS. In addition, the regeneration of ZS-MM catalyst showed that it had a good hydrothermal stability. The differences on coking behaviors on the two catalysts were due to their different acidic properties and textures. | Ting Bai Xin Zhang Feng Wang Wenting Qu Xiling Liu Chao Duan | 2016 | Journal of Energy Chemistry2016，25，3： | 1 |
| 3 | Enantioselective effects of imazethapyr residues on Arabidopsis thaliana metabolic profile and phyllosphere microbial communities显示文摘Imazethapyr(IM)is a widely used acetolactate synthase-inhibiting chiral herbicide.It has long-term residuals that may be absorbed by the human body through the edible parts of plants,such as vegetable leaves or fruits.Here,we selected a model plant,Arabidopsis thaliana,to determine the effects of R-IM and S-IM on its leaf structure,photosynthetic efficiency,and metabolites,as well as the structures of microorganisms in the phyllosphere,after 7 days of exposure.Our results indicated enantiomeric differences in plant growth between R-IM and S-IM;133μg/kg R-IM showed heavier inhibition of photosynthetic efficiency and greater changes to subcellular structure than S-IM.R-IM and S-IM also had different effects on metabolism and leaf microorganisms.S-IM mainly increased lipid compounds and decreased amino acids,while R-IM increased sugar accumulation.The relative abundance of Moraxellaceae human pathogenic bacteria was increased by R-IM treatment,indicating that R-IM treatment may increase leaf surface pathogenic bacteria.Our research provides a new perspective for evaluating the harmfulness of pesticide residues in soil,phyllosphere microbiome changes via the regulation of plant metabolism,and induced pathogenic bacterial accumulation risks. | Qianqiu Zhao Wanyue Liu Yan Li Mingjing Ke Qian Qu Wenting Yuan Xiangliang Pan Haifeng Qian | 2020 | Journal of Environmental Sciences2020，32，7： | 0 |
| 4 | 4-39 Identification of Flavonoids and Expression of Anthocyanin Biosynthetic Genes in Leaf Color Mutant Induced by Carbon Ion Beam in Wandering Jew(Tradescantia uminensis)显示文摘Leaf color mutants are ideal materials for studying physiological processes in plants.Here,a thermos-sensitive leaf-color mutant of Green wandering jew was isolated after carbon ions irradiation,which was designated as mt.The color of young mutant leaves was more sensitive to variations of temperature,however,the young leaves of wild type remained green under low-temperature conditions(6℃-20℃).To elucidate the characteristics of pigmentation in mutant leaves under room temperature conditions(25℃)and low-temperature conditions(7℃),the ultra-structural,pigment composition,molecular mechanisms and anthocyanin accumulation involved in this phenomenon have been investigated in four independent experiments. | Liu Ruiyuan Dong Xicun Li Wenjian Qu Ying Jin Wenjie Gu Wenting | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
